tools: move eslint from tools to tools/node_modules

This is required because we need to add the babel-eslint dependency
and it has to be able to resolve "eslint".
babel-eslint is required to support future ES features such as async
iterators and import.meta.

+
+ESLint is a tool for identifying and reporting on patterns found in ECMAScript/JavaScript code. In many ways, it is similar to JSLint and JSHint with a few exceptions:
+
+* ESLint uses [Espree](https://github.com/eslint/espree) for JavaScript parsing.
+* ESLint uses an AST to evaluate patterns in code.
+* ESLint is completely pluggable, every single rule is a plugin and you can add more at runtime.
+
+## Installation and Usage
+
+Prerequisites: [Node.js](https://nodejs.org/en/) (>=4.x), npm version 2+.
+
+There are two ways to install ESLint: globally and locally.
+
+### Local Installation and Usage
+
+If you want to include ESLint as part of your project's build system, we recommend installing it locally. You can do so using npm:
+
+```
+$ npm install eslint --save-dev
+```
+
+You should then setup a configuration file:
+
+```
+$ ./node_modules/.bin/eslint --init
+```
+
+After that, you can run ESLint on any file or directory like this:
+
+```
+$ ./node_modules/.bin/eslint yourfile.js
+```
+
+Any plugins or shareable configs that you use must also be installed locally to work with a locally-installed ESLint.
+
+### Global Installation and Usage
+
+If you want to make ESLint available to tools that run across all of your projects, we recommend installing ESLint globally. You can do so using npm:
+
+```
+$ npm install -g eslint
+```
+
+You should then setup a configuration file:
+
+```
+$ eslint --init
+```
+
+After that, you can run ESLint on any file or directory like this:
+
+```
+$ eslint yourfile.js
+```
+
+Any plugins or shareable configs that you use must also be installed globally to work with a globally-installed ESLint.
+
+**Note:** `eslint --init` is intended for setting up and configuring ESLint on a per-project basis and will perform a local installation of ESLint and its plugins in the directory in which it is run. If you prefer using a global installation of ESLint, any plugins used in your configuration must also be installed globally.
+
+## Configuration
+
+After running `eslint --init`, you'll have a `.eslintrc` file in your directory. In it, you'll see some rules configured like this:
+
+```json
+{
+    "rules": {
+        "semi": ["error", "always"],
+        "quotes": ["error", "double"]
+    }
+}
+```
+
+The names `"semi"` and `"quotes"` are the names of [rules](https://eslint.org/docs/rules) in ESLint. The first value is the error level of the rule and can be one of these values:
+
+* `"off"` or `0` - turn the rule off
+* `"warn"` or `1` - turn the rule on as a warning (doesn't affect exit code)
+* `"error"` or `2` - turn the rule on as an error (exit code will be 1)
+
+The three error levels allow you fine-grained control over how ESLint applies rules (for more configuration options and details, see the [configuration docs](https://eslint.org/docs/user-guide/configuring)).

+## Releases
+
+We have scheduled releases every two weeks on Friday or Saturday.
+
+## Code of Conduct
+
+ESLint adheres to the [JS Foundation Code of Conduct](https://js.foundation/community/code-of-conduct).
+
+## Filing Issues
+
+Before filing an issue, please be sure to read the guidelines for what you're reporting:
+
+* [Bug Report](https://eslint.org/docs/developer-guide/contributing/reporting-bugs)
+* [Propose a New Rule](https://eslint.org/docs/developer-guide/contributing/new-rules)
+* [Proposing a Rule Change](https://eslint.org/docs/developer-guide/contributing/rule-changes)
+* [Request a Change](https://eslint.org/docs/developer-guide/contributing/changes)
+
+## Semantic Versioning Policy
+
+ESLint follows [semantic versioning](http://semver.org). However, due to the nature of ESLint as a code quality tool, it's not always clear when a minor or major version bump occurs. To help clarify this for everyone, we've defined the following semantic versioning policy for ESLint:
+
+* Patch release (intended to not break your lint build)
+    * A bug fix in a rule that results in ESLint reporting fewer errors.
+    * A bug fix to the CLI or core (including formatters).
+    * Improvements to documentation.
+    * Non-user-facing changes such as refactoring code, adding, deleting, or modifying tests, and increasing test coverage.
+    * Re-releasing after a failed release (i.e., publishing a release that doesn't work for anyone).
+* Minor release (might break your lint build)
+    * A bug fix in a rule that results in ESLint reporting more errors.
+    * A new rule is created.
+    * A new option to an existing rule that does not result in ESLint reporting more errors by default.
+    * An existing rule is deprecated.
+    * A new CLI capability is created.
+    * New capabilities to the public API are added (new classes, new methods, new arguments to existing methods, etc.).
+    * A new formatter is created.
+* Major release (likely to break your lint build)
+    * `eslint:recommended` is updated.
+    * A new option to an existing rule that results in ESLint reporting more errors by default.
+    * An existing formatter is removed.
+    * Part of the public API is removed or changed in an incompatible way.
+
+According to our policy, any minor update may report more errors than the previous release (ex: from a bug fix). As such, we recommend using the tilde (`~`) in `package.json` e.g. `"eslint": "~3.1.0"` to guarantee the results of your builds.

+
+## Frequently Asked Questions
+
+### How is ESLint different from JSHint?
+
+The most significant difference is that ESlint has pluggable linting rules. That means you can use the rules it comes with, or you can extend it with rules created by others or by yourself!
+
+### How does ESLint performance compare to JSHint?
+
+ESLint is slower than JSHint, usually 2-3x slower on a single file. This is because ESLint uses Espree to construct an AST before it can evaluate your code whereas JSHint evaluates your code as it's being parsed. The speed is also based on the number of rules you enable; the more rules you enable, the slower the process.
+
+Despite being slower, we believe that ESLint is fast enough to replace JSHint without causing significant pain.
+
+### I heard ESLint is going to replace JSCS?
+
+Yes. Since we are solving the same problems, ESLint and JSCS teams have decided to join forces and work together in the development of ESLint instead of competing with each other. You can read more about this in both [ESLint](https://eslint.org/blog/2016/04/welcoming-jscs-to-eslint) and [JSCS](https://medium.com/@markelog/jscs-end-of-the-line-bc9bf0b3fdb2#.u76sx334n) announcements.
+
+### So, should I stop using JSCS and start using ESLint?
+
+Maybe, depending on how much you need it. [JSCS has reached end of life](https://eslint.org/blog/2016/07/jscs-end-of-life), but if it is working for you then there is no reason to move yet. We are still working to smooth the transition. You can see our progress [here](https://github.com/eslint/eslint/milestones/JSCS%20Compatibility). We’ll announce when all of the changes necessary to support JSCS users in ESLint are complete and will start encouraging JSCS users to switch to ESLint at that time.
+
+If you are having issues with JSCS, you can try to move to ESLint. We are focusing our time and energy on JSCS compatibility issues.
+
+### Is ESLint just linting or does it also check style?
+
+ESLint does both traditional linting (looking for problematic patterns) and style checking (enforcement of conventions). You can use it for both.
+
+### Why can't ESLint find my plugins?
+
+ESLint can be [globally or locally installed](#installation-and-usage). If you install ESLint globally, your plugins must also be installed globally; if you install ESLint locally, your plugins must also be installed locally.
+
+If you are trying to run globally, make sure your plugins are installed globally (use `npm ls -g`).
+
+If you are trying to run locally:
+
+* Make sure your plugins (and ESLint) are both in your project's `package.json` as devDependencies (or dependencies, if your project uses ESLint at runtime).
+* Make sure you have run `npm install` and all your dependencies are installed.
+
+In all cases, make sure your plugins' peerDependencies have been installed as well. You can use `npm view eslint-plugin-myplugin peerDepencies` to see what peer dependencies `eslint-plugin-myplugin` has.
+
+### Does ESLint support JSX?
+
+Yes, ESLint natively supports parsing JSX syntax (this must be enabled in [configuration](https://eslint.org/docs/user-guide/configuring)). Please note that supporting JSX syntax *is not* the same as supporting React. React applies specific semantics to JSX syntax that ESLint doesn't recognize. We recommend using [eslint-plugin-react](https://www.npmjs.com/package/eslint-plugin-react) if you are using React and want React semantics.
+
+### What about ECMAScript 6 support?
+
+ESLint has full support for ECMAScript 6. By default, this support is off. You can enable ECMAScript 6 syntax and global variables through [configuration](https://eslint.org/docs/user-guide/configuring).
+
+### What about experimental features?
+
+ESLint doesn't natively support experimental ECMAScript language features. You can use [babel-eslint](https://github.com/babel/babel-eslint) to use any option available in Babel.
+
+Once a language feature has been adopted into the ECMAScript standard (stage 4 according to the [TC39 process](https://tc39.github.io/process-document/)), we will accept issues and pull requests related to the new feature, subject to our [contributing guidelines](https://eslint.org/docs/developer-guide/contributing). Until then, please use the appropriate parser and plugin(s) for your experimental feature.

+     * (
+     *     [
+     *         bar
+     *     ]
+     * )
+     *
+     * ([
+     *     bar
+     * ])
+     *
+     * Based on the first case, it's clear that the `bar` token needs to have an offset of 1 indent level (4 spaces) from
+     * the `[` token, and the `[` token has to have an offset of 1 indent level from the `(` token. Since the `(` token is
+     * the first on its line (with an indent of 0 spaces), the `bar` token needs to be offset by 2 indent levels (8 spaces)
+     * from the start of its line.
+     *
+     * However, in the second case `bar` should only be indented by 4 spaces. This is because the offset of 1 indent level
+     * between the `(` and the `[` tokens gets "collapsed" because the two tokens are on the same line. As a result, the
+     * `(` token is mapped to the `[` token with an offset of 0, and the rule correctly decides that `bar` should be indented
+     * by 1 indent level from the start of the line.
+     *
+     * This is useful because rule listeners can usually just call `setDesiredOffset` for all the tokens in the node,
+     * without needing to check which lines those tokens are on.
+     *
+     * Note that since collapsing only occurs when two tokens are on the same line, there are a few cases where non-intuitive
+     * behavior can occur. For example, consider the following cases:
+     *
+     * foo(
+     * ).
+     *     bar(
+     *         baz
+     *     )
+     *
+     * foo(
+     * ).bar(
+     *     baz
+     * )
+     *
+     * Based on the first example, it would seem that `bar` should be offset by 1 indent level from `foo`, and `baz`
+     * should be offset by 1 indent level from `bar`. However, this is not correct, because it would result in `baz`
+     * being indented by 2 indent levels in the second case (since `foo`, `bar`, and `baz` are all on separate lines, no
+     * collapsing would occur).
+     *
+     * Instead, the correct way would be to offset `baz` by 1 level from `bar`, offset `bar` by 1 level from the `)`, and
+     * offset the `)` by 0 levels from `foo`. This ensures that the offset between `bar` and the `)` are correctly collapsed
+     * in the second case.
+     *

+     * Sets the desired offset of all tokens in a range

+     * Moreover, the offset of any given token is usually updated multiple times (roughly once for each node that contains
+     * it). This means that the offset of each token is updated O(AST depth) times.
+     * It would not be performant to store and update the offsets for each token independently, because the rule would end
+     * up having a time complexity of O(number of tokens * AST depth), which is quite slow for large files.
+     *
+     * Instead, the offset tree is represented as a collection of contiguous offset ranges in a file. For example, the following
+     * list could represent the state of the offset tree at a given point:
+     *
+     * * Tokens starting in the interval [0, 15) are aligned with the beginning of the file
+     * * Tokens starting in the interval [15, 30) are offset by 1 indent level from the `bar` token

+     * * Tokens starting in the interval [43, 820) are offset by 2 indent levels from the `bar` token
+     * * Tokens starting in the interval [820, ∞) are offset by 1 indent level from the `baz` token
+     *
+     * The `setDesiredOffsets` methods inserts ranges like the ones above. The third line above would be inserted by using:
+     * `setDesiredOffsets([30, 43], fooToken, 1);`
+     *
+     * @param {[number, number]} range A [start, end] pair. All tokens with range[0] <= token.start < range[1] will have the offset applied.
+     * @param {Token} fromToken The token that this is offset from

+         * ## A variable is declared on a SwitchCase node.
+         *
+         * If this rule modifies 'var' declarations on a SwitchCase node, it

+         *
+         * ## A variable is redeclared.
+         *
+         * The language spec disallows redeclarations of `let` declarations.
+         * Those variables would cause syntax errors.
+         *
+         * ## A variable is used from outside the scope.
+         *
+         * The language spec disallows accesses from outside of the scope for
+         * `let` declarations. Those variables would cause reference errors.
+         *
+         * ## A variable is used from a closure within a loop.
+         *
+         * A `var` declaration within a loop shares the same variable instance
+         * across all loop iterations, while a `let` declaration creates a new
+         * instance for each iteration. This means if a variable in a loop is
+         * referenced by any closure, changing it from `var` to `let` would
+         * change the behavior in a way that is generally unsafe.
+         *
+         * ## A variable might be used before it is assigned within a loop.
+         *
+         * Within a loop, a `let` declaration without an initializer will be
+         * initialized to null, while a `var` declaration will retain its value
+         * from the previous iteration, so it is only safe to change `var` to
+         * `let` if we can statically determine that the variable is always
+         * assigned a value before its first access in the loop body. To keep
+         * the implementation simple, we only convert `var` to `let` within
+         * loops when the variable is a loop assignee or the declaration has an
+         * initializer.
+         *

+# Acorn-JSX
+
+[![Build Status](https://travis-ci.org/RReverser/acorn-jsx.svg?branch=master)](https://travis-ci.org/RReverser/acorn-jsx)
+[![NPM version](https://img.shields.io/npm/v/acorn-jsx.svg)](https://www.npmjs.org/package/acorn-jsx)
+
+This is plugin for [Acorn](http://marijnhaverbeke.nl/acorn/) - a tiny, fast JavaScript parser, written completely in JavaScript.
+
+It was created as an experimental alternative, faster [React.js JSX](http://facebook.github.io/react/docs/jsx-in-depth.html) parser.
+
+According to [benchmarks](https://github.com/RReverser/acorn-jsx/blob/master/test/bench.html), Acorn-JSX is 2x faster than official [Esprima-based parser](https://github.com/facebook/esprima) when location tracking is turned on in both (call it "source maps enabled mode"). At the same time, it consumes all the ES6+JSX syntax that can be consumed by Esprima-FB (this is proved by [official tests](https://github.com/RReverser/acorn-jsx/blob/master/test/tests-jsx.js)).
+
+**UPDATE [14-Apr-2015]**: Facebook implementation started [deprecation process](https://github.com/facebook/esprima/issues/111) in favor of Acorn + Acorn-JSX + Babel for parsing and transpiling JSX syntax.
+
+## Transpiler
+
+Please note that this tool only parses source code to JSX AST, which is useful for various language tools and services. If you want to transpile your code to regular ES5-compliant JavaScript with source map, check out the [babel transpiler](https://babeljs.io/) which uses `acorn-jsx` under the hood.
+
+## Usage
+
+You can use module directly in order to get Acorn instance with plugin installed:
+
+```javascript
+var acorn = require('acorn-jsx');
+```
+
+Or you can use `inject.js` for injecting plugin into your own version of Acorn like following:
+
+```javascript
+var acorn = require('acorn-jsx/inject')(require('./custom-acorn'));
+```
+
+Then, use `plugins` option whenever you need to support JSX while parsing:
+
+```javascript
+var ast = acorn.parse(code, {
+  plugins: { jsx: true }
+});
+```
+
+Note that official spec doesn't support mix of XML namespaces and object-style access in tag names (#27) like in `<namespace:Object.Property />`, so it was deprecated in `acorn-jsx@3.0`. If you still want to opt-in to support of such constructions, you can pass the following option:
+
+```javascript
+var ast = acorn.parse(code, {
+  plugins: {
+    jsx: { allowNamespacedObjects: true }
+  }
+});
+```
+
+Also, since most apps use pure React transformer, a new option was introduced that allows to prohibit namespaces completely:
+
+```javascript
+var ast = acorn.parse(code, {
+  plugins: {
+    jsx: { allowNamespaces: false }
+  }
+});
+```
+
+Note that by default `allowNamespaces` is enabled for spec compliancy.
+

+
+[![Build Status](https://travis-ci.org/ternjs/acorn.svg?branch=master)](https://travis-ci.org/ternjs/acorn)
+[![NPM version](https://img.shields.io/npm/v/acorn.svg)](https://www.npmjs.com/package/acorn)  
+[Author funding status: ![maintainer happiness](https://marijnhaverbeke.nl/fund/status_s.png?force)](https://marijnhaverbeke.nl/fund/)
+
+A tiny, fast JavaScript parser, written completely in JavaScript.
+
+## Community
+
+Acorn is open source software released under an
+[MIT license](https://github.com/ternjs/acorn/blob/master/LICENSE).
+
+You are welcome to
+[report bugs](https://github.com/ternjs/acorn/issues) or create pull
+requests on [github](https://github.com/ternjs/acorn). For questions
+and discussion, please use the
+[Tern discussion forum](https://discuss.ternjs.net).
+
+## Installation
+
+The easiest way to install acorn is with [`npm`][npm].
+
+[npm]: https://www.npmjs.com/
+
+```sh
+npm install acorn
+```
+
+Alternately, download the source.
+
+```sh
+git clone https://github.com/ternjs/acorn.git
+```
+
+## Components
+
+When run in a CommonJS (node.js) or AMD environment, exported values
+appear in the interfaces exposed by the individual files, as usual.
+When loaded in the browser (Acorn works in any JS-enabled browser more
+recent than IE5) without any kind of module management, a single
+global object `acorn` will be defined, and all the exported properties
+will be added to that.
+
+### Main parser
+
+This is implemented in `dist/acorn.js`, and is what you get when you
+`require("acorn")` in node.js.
+
+**parse**`(input, options)` is used to parse a JavaScript program.
+The `input` parameter is a string, `options` can be undefined or an
+object setting some of the options listed below. The return value will
+be an abstract syntax tree object as specified by the
+[ESTree spec][estree].
+
+When  encountering   a  syntax   error,  the   parser  will   raise  a
+`SyntaxError` object with a meaningful  message. The error object will
+have a `pos` property that indicates the character offset at which the
+error occurred,  and a `loc`  object that contains a  `{line, column}`
+object referring to that same position.
+
+[estree]: https://github.com/estree/estree
+
+- **ecmaVersion**: Indicates the ECMAScript version to parse. Must be
+  either 3, 5, 6, or 7. This influences support for strict mode, the set
+  of reserved words, and support for new syntax features. Default is 6.
+
+  **NOTE**: Only 'stage 4' (finalized) ECMAScript 7 features are being
+  implemented by Acorn. That means that most of the draft standard is
+  not yet being parsed.
+
+- **sourceType**: Indicate the mode the code should be parsed in. Can be
+  either `"script"` or `"module"`.
+
+- **onInsertedSemicolon**: If given a callback, that callback will be
+  called whenever a missing semicolon is inserted by the parser. The
+  callback will be given the character offset of the point where the
+  semicolon is inserted as argument, and if `locations` is on, also a
+  `{line, column}` object representing this position.
+
+- **onTrailingComma**: Like `onInsertedSemicolon`, but for trailing
+  commas.
+
+- **allowReserved**: If `false`, using a reserved word will generate
+  an error. Defaults to `true` for `ecmaVersion` 3, `false` for higher
+  versions. When given the value `"never"`, reserved words and
+  keywords can also not be used as property names (as in Internet
+  Explorer's old parser).
+
+- **allowReturnOutsideFunction**: By default, a return statement at
+  the top level raises an error. Set this to `true` to accept such
+  code.
+
+- **allowImportExportEverywhere**: By default, `import` and `export`
+  declarations can only appear at a program's top level. Setting this
+  option to `true` allows them anywhere where a statement is allowed.
+
+- **allowHashBang**: When this is enabled (off by default), if the
+  code starts with the characters `#!` (as in a shellscript), the
+  first line will be treated as a comment.
+
+- **locations**: When `true`, each node has a `loc` object attached
+  with `start` and `end` subobjects, each of which contains the
+  one-based line and zero-based column numbers in `{line, column}`
+  form. Default is `false`.
+
+- **onToken**: If a function is passed for this option, each found
+  token will be passed in same format as tokens returned from
+  `tokenizer().getToken()`.
+
+  If array is passed, each found token is pushed to it.
+
+  Note that you are not allowed to call the parser from the
+  callback—that will corrupt its internal state.
+
+- **onComment**: If a function is passed for this option, whenever a
+  comment is encountered the function will be called with the
+  following parameters:
+
+  - `block`: `true` if the comment is a block comment, false if it
+    is a line comment.
+  - `text`: The content of the comment.
+  - `start`: Character offset of the start of the comment.
+  - `end`: Character offset of the end of the comment.
+
+  When the `locations` options is on, the `{line, column}` locations
+  of the comment’s start and end are passed as two additional
+  parameters.
+
+  If array is passed for this option, each found comment is pushed
+  to it as object in Esprima format:
+
+  ```javascript
+  {
+    "type": "Line" | "Block",
+    "value": "comment text",
+    "start": Number,
+    "end": Number,
+    // If `locations` option is on:
+    "loc": {
+      "start": {line: Number, column: Number}
+      "end": {line: Number, column: Number}
+    },
+    // If `ranges` option is on:
+    "range": [Number, Number]
+  }
+  ```
+
+  Note that you are not allowed to call the parser from the
+  callback—that will corrupt its internal state.
+
+- **ranges**: Nodes have their start and end characters offsets
+  recorded in `start` and `end` properties (directly on the node,
+  rather than the `loc` object, which holds line/column data. To also
+  add a [semi-standardized][range] `range` property holding a
+  `[start, end]` array with the same numbers, set the `ranges` option
+  to `true`.
+
+- **program**: It is possible to parse multiple files into a single
+  AST by passing the tree produced by parsing the first file as the
+  `program` option in subsequent parses. This will add the toplevel
+  forms of the parsed file to the "Program" (top) node of an existing
+  parse tree.
+
+- **sourceFile**: When the `locations` option is `true`, you can pass
+  this option to add a `source` attribute in every node’s `loc`
+  object. Note that the contents of this option are not examined or
+  processed in any way; you are free to use whatever format you
+  choose.
+
+- **directSourceFile**: Like `sourceFile`, but a `sourceFile` property
+  will be added (regardless of the `location` option) directly to the
+  nodes, rather than the `loc` object.
+
+- **preserveParens**: If this option is `true`, parenthesized expressions
+  are represented by (non-standard) `ParenthesizedExpression` nodes
+  that have a single `expression` property containing the expression
+  inside parentheses.
+
+[range]: https://bugzilla.mozilla.org/show_bug.cgi?id=745678
+
+**parseExpressionAt**`(input, offset, options)` will parse a single
+expression in a string, and return its AST. It will not complain if
+there is more of the string left after the expression.
+
+**getLineInfo**`(input, offset)` can be used to get a `{line,
+column}` object for a given program string and character offset.
+
+**tokenizer**`(input, options)` returns an object with a `getToken`
+method that can be called repeatedly to get the next token, a `{start,
+end, type, value}` object (with added `loc` property when the
+`locations` option is enabled and `range` property when the `ranges`
+option is enabled). When the token's type is `tokTypes.eof`, you
+should stop calling the method, since it will keep returning that same
+token forever.
+
+In ES6 environment, returned result can be used as any other
+protocol-compliant iterable:
+
+```javascript
+for (let token of acorn.tokenizer(str)) {
+  // iterate over the tokens
+}
+
+// transform code to array of tokens:
+var tokens = [...acorn.tokenizer(str)];
+```
+
+**tokTypes** holds an object mapping names to the token type objects
+that end up in the `type` properties of tokens.
+
+#### Note on using with [Escodegen][escodegen]
+
+Escodegen supports generating comments from AST, attached in
+Esprima-specific format. In order to simulate same format in
+Acorn, consider following example:
+
+```javascript
+var comments = [], tokens = [];
+
+var ast = acorn.parse('var x = 42; // answer', {
+	// collect ranges for each node
+	ranges: true,
+	// collect comments in Esprima's format
+	onComment: comments,
+	// collect token ranges
+	onToken: tokens
+});
+
+// attach comments using collected information
+escodegen.attachComments(ast, comments, tokens);
+
+// generate code
+console.log(escodegen.generate(ast, {comment: true}));
+// > 'var x = 42;    // answer'
+```

+
+### dist/acorn_loose.js ###
+
+This file implements an error-tolerant parser. It exposes a single
+function. The loose parser is accessible in node.js via `require("acorn/dist/acorn_loose")`.
+
+**parse_dammit**`(input, options)` takes the same arguments and
+returns the same syntax tree as the `parse` function in `acorn.js`,
+but never raises an error, and will do its best to parse syntactically
+invalid code in as meaningful a way as it can. It'll insert identifier
+nodes with name `"✖"` as placeholders in places where it can't make
+sense of the input. Depends on `acorn.js`, because it uses the same
+tokenizer.
+
+### dist/walk.js ###
+
+Implements an abstract syntax tree walker. Will store its interface in
+`acorn.walk` when loaded without a module system.
+
+**simple**`(node, visitors, base, state)` does a 'simple' walk over
+a tree. `node` should be the AST node to walk, and `visitors` an
+object with properties whose names correspond to node types in the
+[ESTree spec][estree]. The properties should contain functions
+that will be called with the node object and, if applicable the state
+at that point. The last two arguments are optional. `base` is a walker
+algorithm, and `state` is a start state. The default walker will
+simply visit all statements and expressions and not produce a
+meaningful state. (An example of a use of state is to track scope at
+each point in the tree.)
+
+**ancestor**`(node, visitors, base, state)` does a 'simple' walk over
+a tree, building up an array of ancestor nodes (including the current node)
+and passing the array to the callbacks as a third parameter.
+
+**recursive**`(node, state, functions, base)` does a 'recursive'
+walk, where the walker functions are responsible for continuing the
+walk on the child nodes of their target node. `state` is the start
+state, and `functions` should contain an object that maps node types
+to walker functions. Such functions are called with `(node, state, c)`
+arguments, and can cause the walk to continue on a sub-node by calling
+the `c` argument on it with `(node, state)` arguments. The optional
+`base` argument provides the fallback walker functions for node types
+that aren't handled in the `functions` object. If not given, the
+default walkers will be used.
+
+**make**`(functions, base)` builds a new walker object by using the
+walker functions in `functions` and filling in the missing ones by
+taking defaults from `base`.
+
+**findNodeAt**`(node, start, end, test, base, state)` tries to
+locate a node in a tree at the given start and/or end offsets, which
+satisfies the predicate `test`. `start` and `end` can be either `null`
+(as wildcard) or a number. `test` may be a string (indicating a node
+type) or a function that takes `(nodeType, node)` arguments and
+returns a boolean indicating whether this node is interesting. `base`
+and `state` are optional, and can be used to specify a custom walker.
+Nodes are tested from inner to outer, so if two nodes match the
+boundaries, the inner one will be preferred.
+
+**findNodeAround**`(node, pos, test, base, state)` is a lot like
+`findNodeAt`, but will match any node that exists 'around' (spanning)
+the given position.
+
+**findNodeAfter**`(node, pos, test, base, state)` is similar to
+`findNodeAround`, but will match all nodes *after* the given position
+(testing outer nodes before inner nodes).
+
+## Command line interface
+
+The `bin/acorn` utility can be used to parse a file from the command
+line. It accepts as arguments its input file and the following
+options:
+
+- `--ecma3|--ecma5|--ecma6|--ecma7`: Sets the ECMAScript version to parse. Default is
+  version 5.
+
+- `--module`: Sets the parsing mode to `"module"`. Is set to `"script"` otherwise.
+
+- `--locations`: Attaches a "loc" object to each node with "start" and
+  "end" subobjects, each of which contains the one-based line and
+  zero-based column numbers in `{line, column}` form.
+
+- `--allow-hash-bang`: If the code starts with the characters #! (as in a shellscript), the first line will be treated as a comment.
+
+- `--compact`: No whitespace is used in the AST output.
+
+- `--silent`: Do not output the AST, just return the exit status.
+
+- `--help`: Print the usage information and quit.
+
+The utility spits out the syntax tree as JSON data.
+
+## Build system
+
+Acorn is written in ECMAScript 6, as a set of small modules, in the
+project's `src` directory, and compiled down to bigger ECMAScript 3
+files in `dist` using [Browserify](http://browserify.org) and
+[Babel](http://babeljs.io/). If you are already using Babel, you can
+consider including the modules directly.
+
+The command-line test runner (`npm test`) uses the ES6 modules. The
+browser-based test page (`test/index.html`) uses the compiled modules.
+The `bin/build-acorn.js` script builds the latter from the former.
+
+If you are working on Acorn, you'll probably want to try the code out
+directly, without an intermediate build step. In your scripts, you can
+register the Babel require shim like this:
+
+    require("babel-core/register")
+
+That will allow you to directly `require` the ES6 modules.
+
+## Plugins
+
+Acorn is designed support allow plugins which, within reasonable
+bounds, redefine the way the parser works. Plugins can add new token
+types and new tokenizer contexts (if necessary), and extend methods in
+the parser object. This is not a clean, elegant API—using it requires
+an understanding of Acorn's internals, and plugins are likely to break
+whenever those internals are significantly changed. But still, it is
+_possible_, in this way, to create parsers for JavaScript dialects
+without forking all of Acorn. And in principle it is even possible to
+combine such plugins, so that if you have, for example, a plugin for
+parsing types and a plugin for parsing JSX-style XML literals, you
+could load them both and parse code with both JSX tags and types.
+
+A plugin should register itself by adding a property to
+`acorn.plugins`, which holds a function. Calling `acorn.parse`, a
+`plugins` option can be passed, holding an object mapping plugin names
+to configuration values (or just `true` for plugins that don't take
+options). After the parser object has been created, the initialization
+functions for the chosen plugins are called with `(parser,
+configValue)` arguments. They are expected to use the `parser.extend`
+method to extend parser methods. For example, the `readToken` method
+could be extended like this:
+
+```javascript
+parser.extend("readToken", function(nextMethod) {
+  return function(code) {
+    console.log("Reading a token!")
+    return nextMethod.call(this, code)
+  }
+})
+```
+
+The `nextMethod` argument passed to `extend`'s second argument is the
+previous value of this method, and should usually be called through to
+whenever the extended method does not handle the call itself.
+
+Similarly, the loose parser allows plugins to register themselves via
+`acorn.pluginsLoose`.  The extension mechanism is the same as for the
+normal parser:
+
+```javascript
+looseParser.extend("readToken", function(nextMethod) {
+  return function() {
+    console.log("Reading a token in the loose parser!")
+    return nextMethod.call(this)
+  }
+})
+```

+// Acorn: Loose parser
+//
+// This module provides an alternative parser (`parse_dammit`) that
+// exposes that same interface as `parse`, but will try to parse
+// anything as JavaScript, repairing syntax error the best it can.
+// There are circumstances in which it will raise an error and give
+// up, but they are very rare. The resulting AST will be a mostly
+// valid JavaScript AST (as per the [Mozilla parser API][api], except
+// that:
+//
+// - Return outside functions is allowed
+//
+// - Label consistency (no conflicts, break only to existing labels)
+//   is not enforced.
+//
+// - Bogus Identifier nodes with a name of `"✖"` are inserted whenever
+//   the parser got too confused to return anything meaningful.
+//
+// [api]: https://developer.mozilla.org/en-US/docs/SpiderMonkey/Parser_API
+//
+// The expected use for this is to *first* try `acorn.parse`, and only
+// if that fails switch to `parse_dammit`. The loose parser might
+// parse badly indented code incorrectly, so **don't** use it as
+// your default parser.
+//
+// Quite a lot of acorn.js is duplicated here. The alternative was to
+// add a *lot* of extra cruft to that file, making it less readable
+// and slower. Copying and editing the code allowed me to make
+// invasive changes and simplifications without creating a complicated
+// tangle.

+// `yield` expression. It is set on all token types that either can
+// directly start an expression (like a quotation mark) or can
+// continue an expression (like the body of a string).

+
+A tiny, fast JavaScript parser, written completely in JavaScript.
+
+## Community
+
+Acorn is open source software released under an
+[MIT license](https://github.com/ternjs/acorn/blob/master/LICENSE).
+
+You are welcome to
+[report bugs](https://github.com/ternjs/acorn/issues) or create pull
+requests on [github](https://github.com/ternjs/acorn). For questions
+and discussion, please use the
+[Tern discussion forum](https://discuss.ternjs.net).
+
+## Installation
+
+The easiest way to install acorn is with [`npm`][npm].
+
+[npm]: https://www.npmjs.com/
+
+```sh
+npm install acorn
+```
+
+Alternately, download the source.
+
+```sh
+git clone https://github.com/ternjs/acorn.git
+```
+
+## Components
+
+When run in a CommonJS (node.js) or AMD environment, exported values
+appear in the interfaces exposed by the individual files, as usual.
+When loaded in the browser (Acorn works in any JS-enabled browser more
+recent than IE5) without any kind of module management, a single
+global object `acorn` will be defined, and all the exported properties
+will be added to that.
+
+### Main parser
+
+This is implemented in `dist/acorn.js`, and is what you get when you
+`require("acorn")` in node.js.
+
+**parse**`(input, options)` is used to parse a JavaScript program.
+The `input` parameter is a string, `options` can be undefined or an
+object setting some of the options listed below. The return value will
+be an abstract syntax tree object as specified by the
+[ESTree spec][estree].
+
+When  encountering   a  syntax   error,  the   parser  will   raise  a
+`SyntaxError` object with a meaningful  message. The error object will
+have a `pos` property that indicates the character offset at which the
+error occurred,  and a `loc`  object that contains a  `{line, column}`
+object referring to that same position.
+
+[estree]: https://github.com/estree/estree
+
+- **ecmaVersion**: Indicates the ECMAScript version to parse. Must be
+  either 3, 5, 6 (2015), 7 (2016), 8 (2017), or 9 (2018, partial
+  support). This influences support for strict mode, the set of
+  reserved words, and support for new syntax features. Default is 7.
+
+  **NOTE**: Only 'stage 4' (finalized) ECMAScript features are being
+  implemented by Acorn.
+
+- **sourceType**: Indicate the mode the code should be parsed in. Can be
+  either `"script"` or `"module"`. This influences global strict mode
+  and parsing of `import` and `export` declarations.
+
+- **onInsertedSemicolon**: If given a callback, that callback will be
+  called whenever a missing semicolon is inserted by the parser. The
+  callback will be given the character offset of the point where the
+  semicolon is inserted as argument, and if `locations` is on, also a
+  `{line, column}` object representing this position.
+
+- **onTrailingComma**: Like `onInsertedSemicolon`, but for trailing
+  commas.
+
+- **allowReserved**: If `false`, using a reserved word will generate
+  an error. Defaults to `true` for `ecmaVersion` 3, `false` for higher
+  versions. When given the value `"never"`, reserved words and
+  keywords can also not be used as property names (as in Internet
+  Explorer's old parser).
+
+- **allowReturnOutsideFunction**: By default, a return statement at
+  the top level raises an error. Set this to `true` to accept such
+  code.
+
+- **allowImportExportEverywhere**: By default, `import` and `export`
+  declarations can only appear at a program's top level. Setting this
+  option to `true` allows them anywhere where a statement is allowed.
+
+- **allowHashBang**: When this is enabled (off by default), if the
+  code starts with the characters `#!` (as in a shellscript), the
+  first line will be treated as a comment.
+
+- **locations**: When `true`, each node has a `loc` object attached
+  with `start` and `end` subobjects, each of which contains the
+  one-based line and zero-based column numbers in `{line, column}`
+  form. Default is `false`.
+
+- **onToken**: If a function is passed for this option, each found
+  token will be passed in same format as tokens returned from
+  `tokenizer().getToken()`.
+
+  If array is passed, each found token is pushed to it.
+
+  Note that you are not allowed to call the parser from the
+  callback—that will corrupt its internal state.
+
+- **onComment**: If a function is passed for this option, whenever a
+  comment is encountered the function will be called with the
+  following parameters:
+
+  - `block`: `true` if the comment is a block comment, false if it
+    is a line comment.
+  - `text`: The content of the comment.
+  - `start`: Character offset of the start of the comment.
+  - `end`: Character offset of the end of the comment.
+
+  When the `locations` options is on, the `{line, column}` locations
+  of the comment’s start and end are passed as two additional
+  parameters.
+
+  If array is passed for this option, each found comment is pushed
+  to it as object in Esprima format:
+
+  ```javascript
+  {
+    "type": "Line" | "Block",
+    "value": "comment text",
+    "start": Number,
+    "end": Number,
+    // If `locations` option is on:
+    "loc": {
+      "start": {line: Number, column: Number}
+      "end": {line: Number, column: Number}
+    },
+    // If `ranges` option is on:
+    "range": [Number, Number]
+  }
+  ```
+
+  Note that you are not allowed to call the parser from the
+  callback—that will corrupt its internal state.
+
+- **ranges**: Nodes have their start and end characters offsets
+  recorded in `start` and `end` properties (directly on the node,
+  rather than the `loc` object, which holds line/column data. To also
+  add a [semi-standardized][range] `range` property holding a
+  `[start, end]` array with the same numbers, set the `ranges` option
+  to `true`.
+
+- **program**: It is possible to parse multiple files into a single
+  AST by passing the tree produced by parsing the first file as the
+  `program` option in subsequent parses. This will add the toplevel
+  forms of the parsed file to the "Program" (top) node of an existing
+  parse tree.
+
+- **sourceFile**: When the `locations` option is `true`, you can pass
+  this option to add a `source` attribute in every node’s `loc`
+  object. Note that the contents of this option are not examined or
+  processed in any way; you are free to use whatever format you
+  choose.
+
+- **directSourceFile**: Like `sourceFile`, but a `sourceFile` property
+  will be added (regardless of the `location` option) directly to the
+  nodes, rather than the `loc` object.
+
+- **preserveParens**: If this option is `true`, parenthesized expressions
+  are represented by (non-standard) `ParenthesizedExpression` nodes
+  that have a single `expression` property containing the expression
+  inside parentheses.
+
+[range]: https://bugzilla.mozilla.org/show_bug.cgi?id=745678
+
+**parseExpressionAt**`(input, offset, options)` will parse a single
+expression in a string, and return its AST. It will not complain if
+there is more of the string left after the expression.
+
+**getLineInfo**`(input, offset)` can be used to get a `{line,
+column}` object for a given program string and character offset.
+
+**tokenizer**`(input, options)` returns an object with a `getToken`
+method that can be called repeatedly to get the next token, a `{start,
+end, type, value}` object (with added `loc` property when the
+`locations` option is enabled and `range` property when the `ranges`
+option is enabled). When the token's type is `tokTypes.eof`, you
+should stop calling the method, since it will keep returning that same
+token forever.
+
+In ES6 environment, returned result can be used as any other
+protocol-compliant iterable:
+
+```javascript
+for (let token of acorn.tokenizer(str)) {
+  // iterate over the tokens
+}
+
+// transform code to array of tokens:
+var tokens = [...acorn.tokenizer(str)];
+```
+
+**tokTypes** holds an object mapping names to the token type objects
+that end up in the `type` properties of tokens.
+
+#### Note on using with [Escodegen][escodegen]
+
+Escodegen supports generating comments from AST, attached in
+Esprima-specific format. In order to simulate same format in
+Acorn, consider following example:
+
+```javascript
+var comments = [], tokens = [];
+
+var ast = acorn.parse('var x = 42; // answer', {
+	// collect ranges for each node
+	ranges: true,
+	// collect comments in Esprima's format
+	onComment: comments,
+	// collect token ranges
+	onToken: tokens
+});
+
+// attach comments using collected information
+escodegen.attachComments(ast, comments, tokens);
+
+// generate code
+console.log(escodegen.generate(ast, {comment: true}));
+// > 'var x = 42;    // answer'
+```

+### dist/acorn_loose.js ###
+
+This file implements an error-tolerant parser. It exposes a single
+function. The loose parser is accessible in node.js via `require("acorn/dist/acorn_loose")`.
+
+**parse_dammit**`(input, options)` takes the same arguments and
+returns the same syntax tree as the `parse` function in `acorn.js`,
+but never raises an error, and will do its best to parse syntactically
+invalid code in as meaningful a way as it can. It'll insert identifier
+nodes with name `"✖"` as placeholders in places where it can't make
+sense of the input. Depends on `acorn.js`, because it uses the same
+tokenizer.
+
+### dist/walk.js ###
+
+Implements an abstract syntax tree walker. Will store its interface in
+`acorn.walk` when loaded without a module system.
+
+**simple**`(node, visitors, base, state)` does a 'simple' walk over
+a tree. `node` should be the AST node to walk, and `visitors` an
+object with properties whose names correspond to node types in the
+[ESTree spec][estree]. The properties should contain functions
+that will be called with the node object and, if applicable the state
+at that point. The last two arguments are optional. `base` is a walker
+algorithm, and `state` is a start state. The default walker will
+simply visit all statements and expressions and not produce a
+meaningful state. (An example of a use of state is to track scope at
+each point in the tree.)
+
+```js
+const acorn = require("acorn")
+const walk = require("acorn/dist/walk")
+
+walk.simple(acorn.parse("let x = 10"), {
+  Literal(node) {
+    console.log(`Found a literal: ${node.value}`)
+  }
+})
+```
+
+**ancestor**`(node, visitors, base, state)` does a 'simple' walk over
+a tree, building up an array of ancestor nodes (including the current node)
+and passing the array to the callbacks as a third parameter.
+
+```js
+const acorn = require("acorn")
+const walk = require("acorn/dist/walk")
+
+walk.ancestor(acorn.parse("foo('hi')"), {
+  Literal(_, ancestors) {
+    console.log("This literal's ancestors are:",
+                ancestors.map(n => n.type))
+  }
+})
+```
+
+**recursive**`(node, state, functions, base)` does a 'recursive'
+walk, where the walker functions are responsible for continuing the
+walk on the child nodes of their target node. `state` is the start
+state, and `functions` should contain an object that maps node types
+to walker functions. Such functions are called with `(node, state, c)`
+arguments, and can cause the walk to continue on a sub-node by calling
+the `c` argument on it with `(node, state)` arguments. The optional
+`base` argument provides the fallback walker functions for node types
+that aren't handled in the `functions` object. If not given, the
+default walkers will be used.
+
+**make**`(functions, base)` builds a new walker object by using the
+walker functions in `functions` and filling in the missing ones by
+taking defaults from `base`.
+
+**full**`(node, callback, base, state)` does a 'full'
+walk over a tree, calling the callback with the arguments (node, state, type)
+for each node
+
+**fullAncestor**`(node, callback, base, state)` does a 'full' walk over
+a tree, building up an array of ancestor nodes (including the current node)
+and passing the array to the callbacks as a third parameter.
+
+```js
+const acorn = require("acorn")
+const walk = require("acorn/dist/walk")
+
+walk.full(acorn.parse("1 + 1"), node => {
+  console.log(`There's a ${node.type} node at ${node.ch}`)
+})
+```
+
+**findNodeAt**`(node, start, end, test, base, state)` tries to
+locate a node in a tree at the given start and/or end offsets, which
+satisfies the predicate `test`. `start` and `end` can be either `null`
+(as wildcard) or a number. `test` may be a string (indicating a node
+type) or a function that takes `(nodeType, node)` arguments and
+returns a boolean indicating whether this node is interesting. `base`
+and `state` are optional, and can be used to specify a custom walker.
+Nodes are tested from inner to outer, so if two nodes match the
+boundaries, the inner one will be preferred.
+
+**findNodeAround**`(node, pos, test, base, state)` is a lot like
+`findNodeAt`, but will match any node that exists 'around' (spanning)
+the given position.
+
+**findNodeAfter**`(node, pos, test, base, state)` is similar to
+`findNodeAround`, but will match all nodes *after* the given position
+(testing outer nodes before inner nodes).
+
+## Command line interface
+
+The `bin/acorn` utility can be used to parse a file from the command
+line. It accepts as arguments its input file and the following
+options:
+
+- `--ecma3|--ecma5|--ecma6|--ecma7|--ecma8|--ecma9`: Sets the ECMAScript version
+  to parse. Default is version 7.
+
+- `--module`: Sets the parsing mode to `"module"`. Is set to `"script"` otherwise.
+
+- `--locations`: Attaches a "loc" object to each node with "start" and
+  "end" subobjects, each of which contains the one-based line and
+  zero-based column numbers in `{line, column}` form.
+
+- `--allow-hash-bang`: If the code starts with the characters #! (as in a shellscript), the first line will be treated as a comment.
+
+- `--compact`: No whitespace is used in the AST output.
+
+- `--silent`: Do not output the AST, just return the exit status.
+
+- `--help`: Print the usage information and quit.
+
+The utility spits out the syntax tree as JSON data.
+
+## Build system
+
+Acorn is written in ECMAScript 6, as a set of small modules, in the
+project's `src` directory, and compiled down to bigger ECMAScript 3
+files in `dist` using [Browserify](http://browserify.org) and
+[Babel](http://babeljs.io/). If you are already using Babel, you can
+consider including the modules directly.
+
+The command-line test runner (`npm test`) uses the ES6 modules. The
+browser-based test page (`test/index.html`) uses the compiled modules.
+The `bin/build-acorn.js` script builds the latter from the former.
+
+If you are working on Acorn, you'll probably want to try the code out
+directly, without an intermediate build step. In your scripts, you can
+register the Babel require shim like this:
+
+    require("babel-core/register")
+
+That will allow you to directly `require` the ES6 modules.
+
+## Plugins
+
+Acorn is designed support allow plugins which, within reasonable
+bounds, redefine the way the parser works. Plugins can add new token
+types and new tokenizer contexts (if necessary), and extend methods in
+the parser object. This is not a clean, elegant API—using it requires
+an understanding of Acorn's internals, and plugins are likely to break
+whenever those internals are significantly changed. But still, it is
+_possible_, in this way, to create parsers for JavaScript dialects
+without forking all of Acorn. And in principle it is even possible to
+combine such plugins, so that if you have, for example, a plugin for
+parsing types and a plugin for parsing JSX-style XML literals, you
+could load them both and parse code with both JSX tags and types.
+
+A plugin should register itself by adding a property to
+`acorn.plugins`, which holds a function. Calling `acorn.parse`, a
+`plugins` option can be passed, holding an object mapping plugin names
+to configuration values (or just `true` for plugins that don't take
+options). After the parser object has been created, the initialization
+functions for the chosen plugins are called with `(parser,
+configValue)` arguments. They are expected to use the `parser.extend`
+method to extend parser methods. For example, the `readToken` method
+could be extended like this:
+
+```javascript
+parser.extend("readToken", function(nextMethod) {
+  return function(code) {
+    console.log("Reading a token!")
+    return nextMethod.call(this, code)
+  }
+})
+```
+
+The `nextMethod` argument passed to `extend`'s second argument is the
+previous value of this method, and should usually be called through to
+whenever the extended method does not handle the call itself.
+
+Similarly, the loose parser allows plugins to register themselves via
+`acorn.pluginsLoose`.  The extension mechanism is the same as for the
+normal parser:
+
+```javascript
+looseParser.extend("readToken", function(nextMethod) {
+  return function() {
+    console.log("Reading a token in the loose parser!")
+    return nextMethod.call(this)
+  }
+})
+```

+// anything as JavaScript, repairing syntax error the best it can.
+// There are circumstances in which it will raise an error and give
+// up, but they are very rare. The resulting AST will be a mostly
+// valid JavaScript AST (as per the [Mozilla parser API][api], except
+// that:
+//
+// - Return outside functions is allowed
+//
+// - Label consistency (no conflicts, break only to existing labels)
+//   is not enforced.
+//
+// - Bogus Identifier nodes with a name of `"✖"` are inserted whenever
+//   the parser got too confused to return anything meaningful.
+//
+// [api]: https://developer.mozilla.org/en-US/docs/SpiderMonkey/Parser_API
+//
+// The expected use for this is to *first* try `acorn.parse`, and only
+// if that fails switch to `parse_dammit`. The loose parser might
+// parse badly indented code incorrectly, so **don't** use it as
+// your default parser.
+//
+// Quite a lot of acorn.js is duplicated here. The alternative was to
+// add a *lot* of extra cruft to that file, making it less readable
+// and slower. Copying and editing the code allowed me to make
+// invasive changes and simplifications without creating a complicated

+// anything as JavaScript, repairing syntax error the best it can.
+// There are circumstances in which it will raise an error and give
+// up, but they are very rare. The resulting AST will be a mostly
+// valid JavaScript AST (as per the [Mozilla parser API][api], except
+// that:
+//
+// - Return outside functions is allowed
+//
+// - Label consistency (no conflicts, break only to existing labels)
+//   is not enforced.
+//
+// - Bogus Identifier nodes with a name of `"✖"` are inserted whenever
+//   the parser got too confused to return anything meaningful.
+//
+// [api]: https://developer.mozilla.org/en-US/docs/SpiderMonkey/Parser_API
+//
+// The expected use for this is to *first* try `acorn.parse`, and only
+// if that fails switch to `parse_dammit`. The loose parser might
+// parse badly indented code incorrectly, so **don't** use it as
+// your default parser.
+//
+// Quite a lot of acorn.js is duplicated here. The alternative was to
+// add a *lot* of extra cruft to that file, making it less readable
+// and slower. Copying and editing the code allowed me to make

+## Install
+
+```
+npm install ajv-keywords
+```
+
+
+## Usage
+
+To add all available keywords:
+
+```javascript
+var Ajv = require('ajv');
+var ajv = new Ajv;
+require('ajv-keywords')(ajv);
+
+ajv.validate({ instanceof: 'RegExp' }, /.*/); // true
+ajv.validate({ instanceof: 'RegExp' }, '.*'); // false
+```
+
+To add a single keyword:
+
+```javascript
+require('ajv-keywords')(ajv, 'instanceof');
+```
+
+To add multiple keywords:
+
+```javascript
+require('ajv-keywords')(ajv, ['typeof', 'instanceof']);
+```
+
+To add a single keyword in browser (to avoid adding unused code):
+
+```javascript
+require('ajv-keywords/keywords/instanceof')(ajv);
+```
+
+
+## Keywords
+
+### `typeof`
+
+Based on JavaScript `typeof` operation.
+
+The value of the keyword should be a string (`"undefined"`, `"string"`, `"number"`, `"object"`, `"function"`, `"boolean"` or `"symbol"`) or array of strings.
+
+To pass validation the result of `typeof` operation on the value should be equal to the string (or one of the strings in the array).
+
+```
+ajv.validate({ typeof: 'undefined' }, undefined); // true
+ajv.validate({ typeof: 'undefined' }, null); // false
+ajv.validate({ typeof: ['undefined', 'object'] }, null); // true
+```
+
+
+### `instanceof`
+
+Based on JavaScript `instanceof` operation.
+
+The value of the keyword should be a string (`"Object"`, `"Array"`, `"Function"`, `"Number"`, `"String"`, `"Date"`, `"RegExp"` or `"Buffer"`) or array of strings.
+
+To pass validation the result of `data instanceof ...` operation on the value should be true:
+
+```
+ajv.validate({ instanceof: 'Array' }, []); // true
+ajv.validate({ instanceof: 'Array' }, {}); // false
+ajv.validate({ instanceof: ['Array', 'Function'] }, function(){}); // true
+```
+
+You can add your own constructor function to be recognised by this keyword:
+
+```javascript
+function MyClass() {}
+var instanceofDefinition = require('ajv-keywords').get('instanceof').definition;
+// or require('ajv-keywords/keywords/instanceof').definition;
+instanceofDefinition.CONSTRUCTORS.MyClass = MyClass;
+
+ajv.validate({ instanceof: 'MyClass' }, new MyClass); // true
+```
+
+
+### `range` and `exclusiveRange`
+
+Syntax sugar for the combination of minimum and maximum keywords, also fails schema compilation if there are no numbers in the range.
+
+The value of this keyword must be the array consisting of two numbers, the second must be greater or equal than the first one.
+
+If the validated value is not a number the validation passes, otherwise to pass validation the value should be greater (or equal) than the first number and smaller (or equal) than the second number in the array. If `exclusiveRange` keyword is present in the same schema and its value is true, the validated value must not be equal to the range boundaries.
+
+```javascript
+var schema = { range: [1, 3] };
+ajv.validate(schema, 1); // true
+ajv.validate(schema, 2); // true
+ajv.validate(schema, 3); // true
+ajv.validate(schema, 0.99); // false
+ajv.validate(schema, 3.01); // false
+
+var schema = { range: [1, 3], exclusiveRange: true };
+ajv.validate(schema, 1.01); // true
+ajv.validate(schema, 2); // true
+ajv.validate(schema, 2.99); // true
+ajv.validate(schema, 1); // false
+ajv.validate(schema, 3); // false
+```
+
+
+### `if`/`then`/`else`
+
+These keywords allow to implement conditional validation. Their values should be valid JSON-schemas.
+
+If the data is valid according to the sub-schema in `if` keyword, then the result is equal to the result of data validation against the sub-schema in `then` keyword, otherwise - in `else` keyword (if `else` is absent, the validation succeeds).
+
+```javascript
+require('ajv-keywords')(ajv, 'if');
+
+var schema = {
+  type: 'array',
+  items: {
+    type: 'integer',
+    minimum: 1,
+    if: { maximum: 10 },
+    then: { multipleOf: 2 },
+    else: { multipleOf: 5 }
+  }
+};
+
+var validItems = [ 2, 4, 6, 8, 10, 15, 20, 25 ]; // etc.
+
+var invalidItems = [ 1, 3, 5, 11, 12 ]; // etc.
+
+ajv.validate(schema, validItems); // true
+ajv.validate(schema, invalidItems); // false
+```
+
+This keyword is [proposed](https://github.com/json-schema-org/json-schema-spec/issues/180) for the future version of JSON-Schema standard.
+
+
+### `switch`
+
+This keyword allows to perform advanced conditional validation.
+
+The value of the keyword is the array of if/then clauses. Each clause is the object with the following properties:
+
+- `if` (optional) - the value is JSON-schema
+- `then` (required) - the value is JSON-schema or boolean
+- `continue` (optional) - the value is boolean
+
+The validation process is dynamic; all clauses are executed sequentially in the following way:
+
+1. `if`:
+    1.  `if` property is JSON-schema according to which the data is:
+        1.  valid => go to step 2.
+        2.  invalid => go to the NEXT clause, if this was the last clause the validation of `switch` SUCCEEDS.
+    2.  `if` property is absent => go to step 2.
+2. `then`:
+    1.  `then` property is `true` or it is JSON-schema according to which the data is valid => go to step 3.
+    2.  `then` property is `false` or it is JSON-schema according to which the data is invalid => the validation of `switch` FAILS.
+3. `continue`:
+    1.  `continue` property is `true` => go to the NEXT clause, if this was the last clause the validation of `switch` SUCCEEDS.
+    2.  `continue` property is `false` or absent => validation of `switch` SUCCEEDS.
+
+```javascript
+require('ajv-keywords')(ajv, 'switch');
+
+var schema = {
+  type: 'array',
+  items: {
+    type: 'integer',
+    'switch': [
+      { if: { not: { minimum: 1 } }, then: false },
+      { if: { maximum: 10 }, then: true },
+      { if: { maximum: 100 }, then: { multipleOf: 10 } },
+      { if: { maximum: 1000 }, then: { multipleOf: 100 } },
+      { then: false }
+    ]
+  }
+};
+
+var validItems = [1, 5, 10, 20, 50, 100, 200, 500, 1000];
+
+var invalidItems = [1, 0, 2000, 11, 57, 123, 'foo'];
+```
+
+__Please note__: this keyword is moved here from Ajv, mainly to preserve backward compatibility. It is unlikely to become a standard. It's preferable to use `if`/`then`/`else` keywords if possible, as they are likely to be added to the standard. The above schema is equivalent to (for example):
+
+```javascript
+{
+  type: 'array',
+  items: {
+    type: 'integer',
+    if: { minimum: 1, maximum: 10 },
+    then: true,
+    else: {
+      if: { maximum: 100 },
+      then: { multipleOf: 10 },
+      else: {
+        if: { maximum: 1000 },
+        then: { multipleOf: 100 },
+        else: false
+      }
+    }
+  }
+}
+```
+
+
+### `select`/`selectCases`/`selectDefault`
+
+These keywords allow to choose the schema to validate the data based on the value of some property in the validated data.
+
+These keywords must be present in the same schema object (`selectDefault` is optional).
+
+The value of `select` keyword should be a [$data reference](https://github.com/epoberezkin/ajv/tree/5.0.2-beta.0#data-reference) that points to any primitive JSON type (string, number, boolean or null) in the data that is validated. You can also use a constant of primitive type as the value of this keyword (e.g., for debugging purposes).
+
+The value of `selectCases` keyword must be an object where each property name is a possible string representation of the value of `select` keyword and each property value is a corresponding schema (from draft-06 it can be boolean) that must be used to validate the data.
+
+The value of `selectDefault` keyword is a schema (from draft-06 it can be boolean) that must be used to validate the data in case `selectCases` has no key equal to the stringified value of `select` keyword.
+
+The validation succeeds in one of the following cases:
+- the validation of data using selected schema succeeds,
+- none of the schemas is selected for validation,
+- the value of select is undefined (no property in the data that the data reference points to).
+
+If `select` value (in data) is not a primitive type the validation fails.
+
+__Please note__: these keywords require Ajv `$data` option to support [$data reference](https://github.com/epoberezkin/ajv/tree/5.0.2-beta.0#data-reference).
+
+
+```javascript
+require('ajv-keywords')(ajv, 'select');
+
+var schema = {
+  type: object,
+  required: ['kind'],
+  properties: {
+    kind: { type: 'string' }
+  },
+  select: { $data: '0/kind' },
+  selectCases: {
+    foo: {
+      required: ['foo'],
+      properties: {
+        kind: {},
+        foo: { type: 'string' }
+      },
+      additionalProperties: false
+    },
+    bar: {
+      required: ['bar'],
+      properties: {
+        kind: {},
+        bar: { type: 'number' }
+      },
+      additionalProperties: false
+    }
+  },
+  selectDefault: {
+    propertyNames: {
+      not: { enum: ['foo', 'bar'] }
+    }
+  }
+};
+
+var validDataList = [
+  { kind: 'foo', foo: 'any' },
+  { kind: 'bar', bar: 1 },
+  { kind: 'anything_else', not_bar_or_foo: 'any value' }
+];
+
+var invalidDataList = [
+  { kind: 'foo' }, // no propery foo
+  { kind: 'bar' }, // no propery bar
+  { kind: 'foo', foo: 'any', another: 'any value' }, // additional property
+  { kind: 'bar', bar: 1, another: 'any value' }, // additional property
+  { kind: 'anything_else', foo: 'any' } // property foo not allowed
+  { kind: 'anything_else', bar: 1 } // property bar not allowed
+];
+```
+
+__Please note__: the current implementation is BETA. It does not allow using relative URIs in $ref keywords in schemas in `selectCases` and `selectDefault` that point outside of these schemas. The workaround is to use absolute URIs (that can point to any (sub-)schema added to Ajv, including those inside the current root schema where `select` is used). See [tests](https://github.com/epoberezkin/ajv-keywords/blob/v2.0.0/spec/tests/select.json#L314).
+
+
+### `patternRequired`
+
+This keyword allows to require the presence of properties that match some pattern(s).
+
+This keyword applies only to objects. If the data is not an object, the validation succeeds.
+
+The value of this keyword should be an array of strings, each string being a regular expression. For data object to be valid each regular expression in this array should match at least one property name in the data object.
+
+If the array contains multiple regular expressions, more than one expression can match the same property name.
+
+```javascript
+var schema = { patternRequired: [ 'f.*o', 'b.*r' ] };
+
+var validData = { foo: 1, bar: 2 };
+var alsoValidData = { foobar: 3 };
+
+var invalidDataList = [ {}, { foo: 1 }, { bar: 2 } ];
+```
+
+
+### `prohibited`
+
+This keyword allows to prohibit that any of the properties in the list is present in the object.
+
+This keyword applies only to objects. If the data is not an object, the validation succeeds.
+
+The value of this keyword should be an array of strings, each string being a property name. For data object to be valid none of the properties in this array should be present in the object.
+
+```
+var schema = { prohibited: ['foo', 'bar']};
+
+var validData = { baz: 1 };
+var alsoValidData = {};
+
+var invalidDataList = [
+  { foo: 1 },
+  { bar: 2 },
+  { foo: 1, bar: 2}
+];
+```
+
+
+### `deepProperties`
+
+This keyword allows to validate deep properties (identified by JSON pointers).
+
+This keyword applies only to objects. If the data is not an object, the validation succeeds.
+
+The value should be an object, where keys are JSON pointers to the data, starting from the current position in data, and the values are JSON schemas. For data object to be valid the value of each JSON pointer should be valid according to the corresponding schema.
+
+```javascript
+var schema = {
+  type: 'object',
+  deepProperties: {
+    "/users/1/role": { "enum": ["admin"] }
+  }
+};
+
+var validData = {
+  users: [
+    {},
+    {
+      id: 123,
+      role: 'admin'
+    }
+  ]
+};
+
+var alsoValidData = {
+  users: {
+    "1": {
+      id: 123,
+      role: 'admin'
+    }
+  }
+};
+
+var invalidData = {
+  users: [
+    {},
+    {
+      id: 123,
+      role: 'user'
+    }
+  ]
+};
+
+var alsoInvalidData = {
+  users: {
+    "1": {
+      id: 123,
+      role: 'user'
+    }
+  }
+};
+```
+
+
+### `deepRequired`
+
+This keyword allows to check that some deep properties (identified by JSON pointers) are available.
+
+This keyword applies only to objects. If the data is not an object, the validation succeeds.
+
+The value should be an array of JSON pointers to the data, starting from the current position in data. For data object to be valid each JSON pointer should be some existing part of the data.
+
+```javascript
+var schema = {
+  type: 'object',
+  deepRequired: ["/users/1/role"]
+};
+
+var validData = {
+  users: [
+    {},
+    {
+      id: 123,
+      role: 'admin'
+    }
+  ]
+};
+
+var invalidData = {
+  users: [
+    {},
+    {
+      id: 123
+    }
+  ]
+};
+```
+
+See [json-schema-org/json-schema-spec#203](https://github.com/json-schema-org/json-schema-spec/issues/203#issue-197211916) for an example of the equivalent schema without `deepRequired` keyword.
+
+
+### `uniqueItemProperties`
+
+The keyword allows to check that some properties in array items are unique.
+
+This keyword applies only to arrays. If the data is not an array, the validation succeeds.
+
+The value of this keyword must be an array of strings - property names that should have unique values across all items.
+
+```javascript
+var schema = { uniqueItemProperties: [ "id", "name" ] };
+
+var validData = [
+  { id: 1 },
+  { id: 2 },
+  { id: 3 }
+];
+
+var invalidData1 = [
+  { id: 1 },
+  { id: 1 },
+  { id: 3 }
+];
+
+var invalidData2 = [
+  { id: 1, name: "taco" },
+  { id: 2, name: "taco" }, // duplicate "name"
+  { id: 3, name: "salsa" }
+];
+```
+
+This keyword is contributed by [@blainesch](https://github.com/blainesch).
+
+
+### `regexp`
+
+This keyword allows to use regular expressions with flags in schemas (the standard `pattern` keyword does not support flags).
+
+This keyword applies only to strings. If the data is not a string, the validation succeeds.
+
+The value of this keyword can be either a string (the result of `regexp.toString()`) or an object with the properties `pattern` and `flags` (the same strings that should be passed to RegExp constructor).
+
+```javascript
+var schema = {
+  type: 'object',
+  properties: {
+    foo: { regexp: '/foo/i' },
+    bar: { regexp: { pattern: 'bar', flags: 'i' } }
+  }
+};
+
+var validData = {
+  foo: 'Food',
+  bar: 'Barmen'
+};
+
+var invalidData = {
+  foo: 'fog',
+  bar: 'bad'
+};
+```
+
+
+### `formatMaximum` / `formatMinimum` and `formatExclusiveMaximum` / `formatExclusiveMinimum`
+
+These keywords allow to define minimum/maximum constraints when the format keyword defines ordering.
+
+These keywords apply only to strings. If the data is not a string, the validation succeeds.
+
+The value of keyword `formatMaximum` (`formatMinimum`) should be a string. This value is the maximum (minimum) allowed value for the data to be valid as determined by `format` keyword.
+
+When this keyword is added, it defines comparison rules for formats `"date"`, `"time"` and `"date-time". Custom formats also can have comparison rules. See [addFormat](https://github.com/epoberezkin/ajv#api-addformat) method.
+
+The value of keyword `formatExclusiveMaximum` (`formatExclusiveMinimum`) should be a boolean value. These keyword cannot be used without `formatMaximum` (`formatMinimum`). If this keyword value is equal to `true`, the data to be valid should not be equal to the value in `formatMaximum` (`formatMinimum`) keyword.
+
+```javascript
+require('ajv-keywords')(ajv, ['formatMinimum', 'formatMaximum']);
+
+var schema = {
+  format: 'date',
+  formatMinimum: '2016-02-06',
+  formatMaximum: '2016-12-27',
+  formatExclusiveMaximum: true
+}
+
+var validDataList = ['2016-02-06', '2016-12-26', 1];
+
+var invalidDataList = ['2016-02-05', '2016-12-27', 'abc'];
+```
+
+
+### `dynamicDefaults`
+
+This keyword allows to assign dynamic defaults to properties, such as timestamps, unique IDs etc.
+
+This keyword only works if `useDefaults` options is used and not inside `anyOf` keywrods etc., in the same way as [default keyword treated by Ajv](https://github.com/epoberezkin/ajv#assigning-defaults).
+
+The keyword should be added on the object level. Its value should be an object with each property corresponding to a property name, in the same way as in standard `properties` keyword. The value of each property can be:
+
+- an identifier of default function (a string)
+- an object with properties `func` (an identifier) and `args` (an object with parameters that will be passed to this function during schema compilation - see examples).
+
+The properties used in `dynamicDefaults` should not be added to `required` keyword (or validation will fail), because unlike `default` this keyword is processed after validation.
+
+There are several predefined dynamic default functions:
+
+- `"timestamp"` - current timestamp in milliseconds
+- `"datetime"` - current date and time as string (ISO, valid according to `date-time` format)
+- `"date"` - current date as string (ISO, valid according to `date` format)
+- `"time"` - current time as string (ISO, valid according to `time` format)
+- `"random"` - pseudo-random number in [0, 1) interval
+- `"randomint"` - pseudo-random integer number. If string is used as a property value, the function will randomly return 0 or 1. If object `{func: 'randomint', max: N}` is used then the default will be an integer number in [0, N) interval.
+- `"seq"` - sequential integer number starting from 0. If string is used as a property value, the default sequence will be used. If object `{func: 'seq', name: 'foo'}` is used then the sequence with name `"foo"` will be used. Sequences are global, even if different ajv instances are used.
+
+```javascript
+var schema = {
+  type: 'object',
+  dynamicDefaults: {
+    ts: 'datetime',
+    r: { func: 'randomint', max: 100 },
+    id: { func: 'seq', name: 'id' }
+  },
+  properties: {
+    ts: {
+      type: 'string',
+      format: 'datetime'
+    },
+    r: {
+      type: 'integer',
+      minimum: 0,
+      maximum: 100,
+      exclusiveMaximum: true
+    },
+    id: {
+      type: 'integer',
+      minimum: 0
+    }
+  }
+};
+
+var data = {};
+ajv.validate(data); // true
+data; // { ts: '2016-12-01T22:07:28.829Z', r: 25, id: 0 }
+
+var data1 = {};
+ajv.validate(data1); // true
+data1; // { ts: '2016-12-01T22:07:29.832Z', r: 68, id: 1 }
+
+ajv.validate(data1); // true
+data1; // didn't change, as all properties were defined
+```
+
+You can add your own dynamic default function to be recognised by this keyword:
+
+```javascript
+var uuid = require('uuid');
+
+function uuidV4() { return uuid.v4(); }
+
+var definition = require('ajv-keywords').get('dynamicDefaults').definition;
+// or require('ajv-keywords/keywords/dynamicDefaults').definition;
+definition.DEFAULTS.uuid = uuidV4;
+
+var schema = {
+  dynamicDefaults: { id: 'uuid' },
+  properties: { id: { type: 'string', format: 'uuid' } }
+};
+
+var data = {};
+ajv.validate(schema, data); // true
+data; // { id: 'a1183fbe-697b-4030-9bcc-cfeb282a9150' };
+
+var data1 = {};
+ajv.validate(schema, data1); // true
+data1; // { id: '5b008de7-1669-467a-a5c6-70fa244d7209' }
+```
+
+You also can define dynamic default that accepts parameters, e.g. version of uuid:
+
+```javascript
+var uuid = require('uuid');
+
+function getUuid(args) {
+  var version = 'v' + (arvs && args.v || 4);
+  return function() {
+    return uuid[version]();
+  };
+}
+
+var definition = require('ajv-keywords').get('dynamicDefaults').definition;
+definition.DEFAULTS.uuid = getUuid;
+
+var schema = {
+  dynamicDefaults: {
+    id1: 'uuid', // v4
+    id2: { func: 'uuid', v: 4 }, // v4
+    id3: { func: 'uuid', v: 1 } // v1
+  }
+};
+```

+__Please note__: Ajv [version 6](https://github.com/epoberezkin/ajv/tree/beta) with [JSON Schema draft-07](http://json-schema.org/work-in-progress) support is released. Use `npm install ajv@beta` to install.
+
+
+## Using version 5
+
+[JSON Schema draft-06](https://trac.tools.ietf.org/html/draft-wright-json-schema-validation-01) is published.
+
+[Ajv version 5.0.0](https://github.com/epoberezkin/ajv/releases/tag/5.0.0) that supports draft-06 is released. It may require either migrating your schemas or updating your code (to continue using draft-04 and v5 schemas).
+
+__Please note__: To use Ajv with draft-04 schemas you need to explicitly add meta-schema to the validator instance:
+
+```javascript
+ajv.addMetaSchema(require('ajv/lib/refs/json-schema-draft-04.json'));
+```

+
+## Performance
+
+Ajv generates code using [doT templates](https://github.com/olado/doT) to turn JSON schemas into super-fast validation functions that are efficient for v8 optimization.
+
+Currently Ajv is the fastest and the most standard compliant validator according to these benchmarks:
+
+- [json-schema-benchmark](https://github.com/ebdrup/json-schema-benchmark) - 50% faster than the second place
+- [jsck benchmark](https://github.com/pandastrike/jsck#benchmarks) - 20-190% faster
+- [z-schema benchmark](https://rawgit.com/zaggino/z-schema/master/benchmark/results.html)
+- [themis benchmark](https://cdn.rawgit.com/playlyfe/themis/master/benchmark/results.html)
+
+
+Performance of different validators by [json-schema-benchmark](https://github.com/ebdrup/json-schema-benchmark):
+
+[![performance](https://chart.googleapis.com/chart?chxt=x,y&cht=bhs&chco=76A4FB&chls=2.0&chbh=32,4,1&chs=600x416&chxl=-1:%7Cajv%7Cis-my-json-valid%7Cjsen%7Cschemasaurus%7Cthemis%7Cz-schema%7Cjsck%7Cjsonschema%7Cskeemas%7Ctv4%7Cjayschema&chd=t:100,68,61,22.8,17.6,6.6,2.7,0.9,0.7,0.4,0.1)](https://github.com/ebdrup/json-schema-benchmark/blob/master/README.md#performance)
+
+
+## Features
+
+- Ajv implements full JSON Schema [draft 6](http://json-schema.org/) and draft 4 standards:
+  - all validation keywords (see [JSON Schema validation keywords](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md))
+  - full support of remote refs (remote schemas have to be added with `addSchema` or compiled to be available)
+  - support of circular references between schemas
+  - correct string lengths for strings with unicode pairs (can be turned off)
+  - [formats](#formats) defined by JSON Schema draft 4 standard and custom formats (can be turned off)
+  - [validates schemas against meta-schema](#api-validateschema)
+- supports [browsers](#using-in-browser) and Node.js 0.10-8.x
+- [asynchronous loading](#asynchronous-schema-compilation) of referenced schemas during compilation
+- "All errors" validation mode with [option allErrors](#options)
+- [error messages with parameters](#validation-errors) describing error reasons to allow creating custom error messages
+- i18n error messages support with [ajv-i18n](https://github.com/epoberezkin/ajv-i18n) package
+- [filtering data](#filtering-data) from additional properties
+- [assigning defaults](#assigning-defaults) to missing properties and items
+- [coercing data](#coercing-data-types) to the types specified in `type` keywords
+- [custom keywords](#defining-custom-keywords)
+- draft-6 keywords `const`, `contains` and `propertyNames`
+- draft-6 boolean schemas (`true`/`false` as a schema to always pass/fail).
+- keywords `switch`, `patternRequired`, `formatMaximum` / `formatMinimum` and `formatExclusiveMaximum` / `formatExclusiveMinimum` from [JSON-schema extension proposals](https://github.com/json-schema/json-schema/wiki/v5-Proposals) with [ajv-keywords](https://github.com/epoberezkin/ajv-keywords) package
+- [$data reference](#data-reference) to use values from the validated data as values for the schema keywords
+- [asynchronous validation](#asynchronous-validation) of custom formats and keywords
+
+Currently Ajv is the only validator that passes all the tests from [JSON Schema Test Suite](https://github.com/json-schema/JSON-Schema-Test-Suite) (according to [json-schema-benchmark](https://github.com/ebdrup/json-schema-benchmark), apart from the test that requires that `1.0` is not an integer that is impossible to satisfy in JavaScript).
+
+
+## Install
+
+```
+npm install ajv
+```
+
+or to install [version 6](https://github.com/epoberezkin/ajv/tree/beta):
+
+```
+npm install ajv@beta
+```
+
+
+## <a name="usage"></a>Getting started
+
+Try it in the Node.js REPL: https://tonicdev.com/npm/ajv
+
+
+The fastest validation call:
+
+```javascript
+var Ajv = require('ajv');
+var ajv = new Ajv(); // options can be passed, e.g. {allErrors: true}
+var validate = ajv.compile(schema);
+var valid = validate(data);
+if (!valid) console.log(validate.errors);
+```
+
+or with less code
+
+```javascript
+// ...
+var valid = ajv.validate(schema, data);
+if (!valid) console.log(ajv.errors);
+// ...
+```
+
+or
+
+```javascript
+// ...
+var valid = ajv.addSchema(schema, 'mySchema')
+               .validate('mySchema', data);
+if (!valid) console.log(ajv.errorsText());
+// ...
+```
+
+See [API](#api) and [Options](#options) for more details.
+
+Ajv compiles schemas to functions and caches them in all cases (using schema serialized with [fast-json-stable-stringify](https://github.com/epoberezkin/fast-json-stable-stringify) or a custom function as a key), so that the next time the same schema is used (not necessarily the same object instance) it won't be compiled again.
+
+The best performance is achieved when using compiled functions returned by `compile` or `getSchema` methods (there is no additional function call).
+
+__Please note__: every time a validation function or `ajv.validate` are called `errors` property is overwritten. You need to copy `errors` array reference to another variable if you want to use it later (e.g., in the callback). See [Validation errors](#validation-errors)
+
+
+## Using in browser
+
+You can require Ajv directly from the code you browserify - in this case Ajv will be a part of your bundle.
+
+If you need to use Ajv in several bundles you can create a separate UMD bundle using `npm run bundle` script (thanks to [siddo420](https://github.com/siddo420)).
+
+Then you need to load Ajv in the browser:
+```html
+<script src="ajv.min.js"></script>
+```
+
+This bundle can be used with different module systems; it creates global `Ajv` if no module system is found.
+
+The browser bundle is available on [cdnjs](https://cdnjs.com/libraries/ajv).
+
+Ajv is tested with these browsers:
+
+[![Sauce Test Status](https://saucelabs.com/browser-matrix/epoberezkin.svg)](https://saucelabs.com/u/epoberezkin)
+
+__Please note__: some frameworks, e.g. Dojo, may redefine global require in such way that is not compatible with CommonJS module format. In such case Ajv bundle has to be loaded before the framework and then you can use global Ajv (see issue [#234](https://github.com/epoberezkin/ajv/issues/234)).
+
+
+## Command line interface
+
+CLI is available as a separate npm package [ajv-cli](https://github.com/jessedc/ajv-cli). It supports:
+
+- compiling JSON-schemas to test their validity
+- BETA: generating standalone module exporting a validation function to be used without Ajv (using [ajv-pack](https://github.com/epoberezkin/ajv-pack))
+- migrate schemas to draft-06 (using [json-schema-migrate](https://github.com/epoberezkin/json-schema-migrate))
+- validating data file(s) against JSON-schema
+- testing expected validity of data against JSON-schema
+- referenced schemas
+- custom meta-schemas
+- files in JSON and JavaScript format
+- all Ajv options
+- reporting changes in data after validation in [JSON-patch](https://tools.ietf.org/html/rfc6902) format
+
+
+## Validation keywords
+
+Ajv supports all validation keywords from draft 4 of JSON-schema standard:
+
+- [type](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#type)
+- [for numbers](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#keywords-for-numbers) - maximum, minimum, exclusiveMaximum, exclusiveMinimum, multipleOf
+- [for strings](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#keywords-for-strings) - maxLength, minLength, pattern, format
+- [for arrays](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#keywords-for-arrays) - maxItems, minItems, uniqueItems, items, additionalItems, [contains](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#contains)
+- [for objects](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#keywords-for-objects) - maxProperties, minProperties, required, properties, patternProperties, additionalProperties, dependencies, [propertyNames](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#propertynames)
+- [for all types](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#keywords-for-all-types) - enum, [const](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#const)
+- [compound keywords](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#compound-keywords) - not, oneOf, anyOf, allOf
+
+With [ajv-keywords](https://github.com/epoberezkin/ajv-keywords) package Ajv also supports validation keywords from [JSON Schema extension proposals](https://github.com/json-schema/json-schema/wiki/v5-Proposals) for JSON-schema standard:
+
+- [switch](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#switch-proposed) - conditional validation with a sequence of if/then clauses
+- [patternRequired](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#patternrequired-proposed) - like `required` but with patterns that some property should match.
+- [formatMaximum, formatMinimum, formatExclusiveMaximum, formatExclusiveMinimum](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#formatmaximum--formatminimum-and-exclusiveformatmaximum--exclusiveformatminimum-proposed) - setting limits for date, time, etc.
+
+See [JSON Schema validation keywords](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md) for more details.
+
+
+## Formats
+
+The following formats are supported for string validation with "format" keyword:
+
+- _date_: full-date according to [RFC3339](http://tools.ietf.org/html/rfc3339#section-5.6).
+- _time_: time with optional time-zone.
+- _date-time_: date-time from the same source (time-zone is mandatory). `date`, `time` and `date-time` validate ranges in `full` mode and only regexp in `fast` mode (see [options](#options)).
+- _uri_: full uri with optional protocol.
+- _url_: [URL record](https://url.spec.whatwg.org/#concept-url).
+- _uri-template_: URI template according to [RFC6570](https://tools.ietf.org/html/rfc6570)
+- _email_: email address.
+- _hostname_: host name according to [RFC1034](http://tools.ietf.org/html/rfc1034#section-3.5).
+- _ipv4_: IP address v4.
+- _ipv6_: IP address v6.
+- _regex_: tests whether a string is a valid regular expression by passing it to RegExp constructor.
+- _uuid_: Universally Unique IDentifier according to [RFC4122](http://tools.ietf.org/html/rfc4122).
+- _json-pointer_: JSON-pointer according to [RFC6901](https://tools.ietf.org/html/rfc6901).
+- _relative-json-pointer_: relative JSON-pointer according to [this draft](http://tools.ietf.org/html/draft-luff-relative-json-pointer-00).
+
+There are two modes of format validation: `fast` and `full`. This mode affects formats `date`, `time`, `date-time`, `uri`, `email`, and `hostname`. See [Options](#options) for details.
+
+You can add additional formats and replace any of the formats above using [addFormat](#api-addformat) method.
+
+The option `unknownFormats` allows changing the default behaviour when an unknown format is encountered. In this case Ajv can either fail schema compilation (default) or ignore it (default in versions before 5.0.0). You also can whitelist specific format(s) to be ignored. See [Options](#options) for details.
+
+You can find patterns used for format validation and the sources that were used in [formats.js](https://github.com/epoberezkin/ajv/blob/master/lib/compile/formats.js).
+
+
+## <a name="ref"></a>Combining schemas with $ref
+
+You can structure your validation logic across multiple schema files and have schemas reference each other using `$ref` keyword.
+
+Example:
+
+```javascript
+var schema = {
+  "$id": "http://example.com/schemas/schema.json",
+  "type": "object",
+  "properties": {
+    "foo": { "$ref": "defs.json#/definitions/int" },
+    "bar": { "$ref": "defs.json#/definitions/str" }
+  }
+};
+
+var defsSchema = {
+  "$id": "http://example.com/schemas/defs.json",
+  "definitions": {
+    "int": { "type": "integer" },
+    "str": { "type": "string" }
+  }
+};
+```
+
+Now to compile your schema you can either pass all schemas to Ajv instance:
+
+```javascript
+var ajv = new Ajv({schemas: [schema, defsSchema]});
+var validate = ajv.getSchema('http://example.com/schemas/schema.json');
+```
+
+or use `addSchema` method:
+
+```javascript
+var ajv = new Ajv;
+var validate = ajv.addSchema(defsSchema)
+                  .compile(schema);
+```
+
+See [Options](#options) and [addSchema](#api) method.
+
+__Please note__:
+- `$ref` is resolved as the uri-reference using schema $id as the base URI (see the example).
+- References can be recursive (and mutually recursive) to implement the schemas for different data structures (such as linked lists, trees, graphs, etc.).
+- You don't have to host your schema files at the URIs that you use as schema $id. These URIs are only used to identify the schemas, and according to JSON Schema specification validators should not expect to be able to download the schemas from these URIs.
+- The actual location of the schema file in the file system is not used.
+- You can pass the identifier of the schema as the second parameter of `addSchema` method or as a property name in `schemas` option. This identifier can be used instead of (or in addition to) schema $id.
+- You cannot have the same $id (or the schema identifier) used for more than one schema - the exception will be thrown.
+- You can implement dynamic resolution of the referenced schemas using `compileAsync` method. In this way you can store schemas in any system (files, web, database, etc.) and reference them without explicitly adding to Ajv instance. See [Asynchronous schema compilation](#asynchronous-schema-compilation).
+
+
+## $data reference
+
+With `$data` option you can use values from the validated data as the values for the schema keywords. See [proposal](https://github.com/json-schema/json-schema/wiki/$data-(v5-proposal)) for more information about how it works.
+
+`$data` reference is supported in the keywords: const, enum, format, maximum/minimum, exclusiveMaximum / exclusiveMinimum, maxLength / minLength, maxItems / minItems, maxProperties / minProperties, formatMaximum / formatMinimum, formatExclusiveMaximum / formatExclusiveMinimum, multipleOf, pattern, required, uniqueItems.
+
+The value of "$data" should be a [JSON-pointer](https://tools.ietf.org/html/rfc6901) to the data (the root is always the top level data object, even if the $data reference is inside a referenced subschema) or a [relative JSON-pointer](http://tools.ietf.org/html/draft-luff-relative-json-pointer-00) (it is relative to the current point in data; if the $data reference is inside a referenced subschema it cannot point to the data outside of the root level for this subschema).
+
+Examples.
+
+This schema requires that the value in property `smaller` is less or equal than the value in the property larger:
+
+```javascript
+var ajv = new Ajv({$data: true});
+
+var schema = {
+  "properties": {
+    "smaller": {
+      "type": "number",
+      "maximum": { "$data": "1/larger" }
+    },
+    "larger": { "type": "number" }
+  }
+};
+
+var validData = {
+  smaller: 5,
+  larger: 7
+};
+
+ajv.validate(schema, validData); // true
+```
+
+This schema requires that the properties have the same format as their field names:
+
+```javascript
+var schema = {
+  "additionalProperties": {
+    "type": "string",
+    "format": { "$data": "0#" }
+  }
+};
+
+var validData = {
+  'date-time': '1963-06-19T08:30:06.283185Z',
+  email: 'joe.bloggs@example.com'
+}
+```
+
+`$data` reference is resolved safely - it won't throw even if some property is undefined. If `$data` resolves to `undefined` the validation succeeds (with the exclusion of `const` keyword). If `$data` resolves to incorrect type (e.g. not "number" for maximum keyword) the validation fails.
+
+
+## $merge and $patch keywords
+
+With the package [ajv-merge-patch](https://github.com/epoberezkin/ajv-merge-patch) you can use the keywords `$merge` and `$patch` that allow extending JSON-schemas with patches using formats [JSON Merge Patch (RFC 7396)](https://tools.ietf.org/html/rfc7396) and [JSON Patch (RFC 6902)](https://tools.ietf.org/html/rfc6902).
+
+To add keywords `$merge` and `$patch` to Ajv instance use this code:
+
+```javascript
+require('ajv-merge-patch')(ajv);
+```
+
+Examples.
+
+Using `$merge`:
+
+```json
+{
+  "$merge": {
+    "source": {
+      "type": "object",
+      "properties": { "p": { "type": "string" } },
+      "additionalProperties": false
+    },
+    "with": {
+      "properties": { "q": { "type": "number" } }
+    }
+  }
+}
+```
+
+Using `$patch`:
+
+```json
+{
+  "$patch": {
+    "source": {
+      "type": "object",
+      "properties": { "p": { "type": "string" } },
+      "additionalProperties": false
+    },
+    "with": [
+      { "op": "add", "path": "/properties/q", "value": { "type": "number" } }
+    ]
+  }
+}
+```
+
+The schemas above are equivalent to this schema:
+
+```json
+{
+  "type": "object",
+  "properties": {
+    "p": { "type": "string" },
+    "q": { "type": "number" }
+  },
+  "additionalProperties": false
+}
+```
+
+The properties `source` and `with` in the keywords `$merge` and `$patch` can use absolute or relative `$ref` to point to other schemas previously added to the Ajv instance or to the fragments of the current schema.
+
+See the package [ajv-merge-patch](https://github.com/epoberezkin/ajv-merge-patch) for more information.
+
+
+## Defining custom keywords
+
+The advantages of using custom keywords are:
+
+- allow creating validation scenarios that cannot be expressed using JSON Schema
+- simplify your schemas
+- help bringing a bigger part of the validation logic to your schemas
+- make your schemas more expressive, less verbose and closer to your application domain
+- implement custom data processors that modify your data (`modifying` option MUST be used in keyword definition) and/or create side effects while the data is being validated
+
+If a keyword is used only for side-effects and its validation result is pre-defined, use option `valid: true/false` in keyword definition to simplify both generated code (no error handling in case of `valid: true`) and your keyword functions (no need to return any validation result).
+
+The concerns you have to be aware of when extending JSON-schema standard with custom keywords are the portability and understanding of your schemas. You will have to support these custom keywords on other platforms and to properly document these keywords so that everybody can understand them in your schemas.
+
+You can define custom keywords with [addKeyword](#api-addkeyword) method. Keywords are defined on the `ajv` instance level - new instances will not have previously defined keywords.
+
+Ajv allows defining keywords with:
+- validation function
+- compilation function
+- macro function
+- inline compilation function that should return code (as string) that will be inlined in the currently compiled schema.
+
+Example. `range` and `exclusiveRange` keywords using compiled schema:
+
+```javascript
+ajv.addKeyword('range', {
+  type: 'number',
+  compile: function (sch, parentSchema) {
+    var min = sch[0];
+    var max = sch[1];
+
+    return parentSchema.exclusiveRange === true
+            ? function (data) { return data > min && data < max; }
+            : function (data) { return data >= min && data <= max; }
+  }
+});
+
+var schema = { "range": [2, 4], "exclusiveRange": true };
+var validate = ajv.compile(schema);
+console.log(validate(2.01)); // true
+console.log(validate(3.99)); // true
+console.log(validate(2)); // false
+console.log(validate(4)); // false
+```
+
+Several custom keywords (typeof, instanceof, range and propertyNames) are defined in [ajv-keywords](https://github.com/epoberezkin/ajv-keywords) package - they can be used for your schemas and as a starting point for your own custom keywords.
+
+See [Defining custom keywords](https://github.com/epoberezkin/ajv/blob/master/CUSTOM.md) for more details.
+
+
+## Asynchronous schema compilation
+
+During asynchronous compilation remote references are loaded using supplied function. See `compileAsync` [method](#api-compileAsync) and `loadSchema` [option](#options).
+
+Example:
+
+```javascript
+var ajv = new Ajv({ loadSchema: loadSchema });
+
+ajv.compileAsync(schema).then(function (validate) {
+  var valid = validate(data);
+  // ...
+});
+
+function loadSchema(uri) {
+  return request.json(uri).then(function (res) {
+    if (res.statusCode >= 400)
+      throw new Error('Loading error: ' + res.statusCode);
+    return res.body;
+  });
+}
+```
+
+__Please note__: [Option](#options) `missingRefs` should NOT be set to `"ignore"` or `"fail"` for asynchronous compilation to work.
+
+
+## Asynchronous validation
+
+Example in Node.js REPL: https://tonicdev.com/esp/ajv-asynchronous-validation
+
+You can define custom formats and keywords that perform validation asynchronously by accessing database or some other service. You should add `async: true` in the keyword or format definition (see [addFormat](#api-addformat), [addKeyword](#api-addkeyword) and [Defining custom keywords](#defining-custom-keywords)).
+
+If your schema uses asynchronous formats/keywords or refers to some schema that contains them it should have `"$async": true` keyword so that Ajv can compile it correctly. If asynchronous format/keyword or reference to asynchronous schema is used in the schema without `$async` keyword Ajv will throw an exception during schema compilation.
+
+__Please note__: all asynchronous subschemas that are referenced from the current or other schemas should have `"$async": true` keyword as well, otherwise the schema compilation will fail.
+
+Validation function for an asynchronous custom format/keyword should return a promise that resolves with `true` or `false` (or rejects with `new Ajv.ValidationError(errors)` if you want to return custom errors from the keyword function). Ajv compiles asynchronous schemas to either [es7 async functions](http://tc39.github.io/ecmascript-asyncawait/) that can optionally be transpiled with [nodent](https://github.com/MatAtBread/nodent) or with [regenerator](https://github.com/facebook/regenerator) or to [generator functions](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/function*) that can be optionally transpiled with regenerator as well. You can also supply any other transpiler as a function. See [Options](#options).
+
+The compiled validation function has `$async: true` property (if the schema is asynchronous), so you can differentiate these functions if you are using both synchronous and asynchronous schemas.
+
+If you are using generators, the compiled validation function can be either wrapped with [co](https://github.com/tj/co) (default) or returned as generator function, that can be used directly, e.g. in [koa](http://koajs.com/) 1.0. `co` is a small library, it is included in Ajv (both as npm dependency and in the browser bundle).
+
+Async functions are currently supported in Chrome 55, Firefox 52, Node.js 7 (with --harmony-async-await) and MS Edge 13 (with flag).
+
+Generator functions are currently supported in Chrome, Firefox and Node.js.
+
+If you are using Ajv in other browsers or in older versions of Node.js you should use one of available transpiling options. All provided async modes use global Promise class. If your platform does not have Promise you should use a polyfill that defines it.
+
+Validation result will be a promise that resolves with validated data or rejects with an exception `Ajv.ValidationError` that contains the array of validation errors in `errors` property.
+
+
+Example:
+
+```javascript
+/**
+ * Default mode is non-transpiled generator function wrapped with `co`.
+ * Using package ajv-async (https://github.com/epoberezkin/ajv-async)
+ * you can auto-detect the best async mode.
+ * In this case, without "async" and "transpile" options
+ * (or with option {async: true})
+ * Ajv will choose the first supported/installed option in this order:
+ * 1. native async function
+ * 2. native generator function wrapped with co
+ * 3. es7 async functions transpiled with nodent
+ * 4. es7 async functions transpiled with regenerator
+ */
+
+var setupAsync = require('ajv-async');
+var ajv = setupAsync(new Ajv);
+
+ajv.addKeyword('idExists', {
+  async: true,
+  type: 'number',
+  validate: checkIdExists
+});
+
+
+function checkIdExists(schema, data) {
+  return knex(schema.table)
+  .select('id')
+  .where('id', data)
+  .then(function (rows) {
+    return !!rows.length; // true if record is found
+  });
+}
+
+var schema = {
+  "$async": true,
+  "properties": {
+    "userId": {
+      "type": "integer",
+      "idExists": { "table": "users" }
+    },
+    "postId": {
+      "type": "integer",
+      "idExists": { "table": "posts" }
+    }
+  }
+};
+
+var validate = ajv.compile(schema);
+
+validate({ userId: 1, postId: 19 })
+.then(function (data) {
+  console.log('Data is valid', data); // { userId: 1, postId: 19 }
+})
+.catch(function (err) {
+  if (!(err instanceof Ajv.ValidationError)) throw err;
+  // data is invalid
+  console.log('Validation errors:', err.errors);
+});
+```
+
+### Using transpilers with asynchronous validation functions.
+
+To use a transpiler you should separately install it (or load its bundle in the browser).
+
+Ajv npm package includes minified browser bundles of regenerator and nodent in dist folder.
+
+
+#### Using nodent
+
+```javascript
+var setupAsync = require('ajv-async');
+var ajv = new Ajv({ /* async: 'es7', */ transpile: 'nodent' });
+setupAsync(ajv);
+var validate = ajv.compile(schema); // transpiled es7 async function
+validate(data).then(successFunc).catch(errorFunc);
+```
+
+`npm install nodent` or use `nodent.min.js` from dist folder of npm package.
+
+
+#### Using regenerator
+
+```javascript
+var setupAsync = require('ajv-async');
+var ajv = new Ajv({ /* async: 'es7', */ transpile: 'regenerator' });
+setupAsync(ajv);
+var validate = ajv.compile(schema); // transpiled es7 async function
+validate(data).then(successFunc).catch(errorFunc);
+```
+
+`npm install regenerator` or use `regenerator.min.js` from dist folder of npm package.
+
+
+#### Using other transpilers
+
+```javascript
+var ajv = new Ajv({ async: 'es7', processCode: transpileFunc });
+var validate = ajv.compile(schema); // transpiled es7 async function
+validate(data).then(successFunc).catch(errorFunc);
+```
+
+See [Options](#options).
+
+
+#### Comparison of async modes
+
+|mode|transpile<br>speed*|run-time<br>speed*|bundle<br>size|
+|---|:-:|:-:|:-:|
+|es7 async<br>(native)|-|0.75|-|
+|generators<br>(native)|-|1.0|-|
+|es7.nodent|1.35|1.1|215Kb|
+|es7.regenerator|1.0|2.7|1109Kb|
+|regenerator|1.0|3.2|1109Kb|
+
+\* Relative performance in Node.js 7.x — smaller is better.
+
+[nodent](https://github.com/MatAtBread/nodent) has several advantages:
+
+- much smaller browser bundle than regenerator
+- almost the same performance of generated code as native generators in Node.js and the latest Chrome
+- much better performance than native generators in other browsers
+- works in IE 9 (regenerator does not)
+
+
+## Filtering data
+
+With [option `removeAdditional`](#options) (added by [andyscott](https://github.com/andyscott)) you can filter data during the validation.
+
+This option modifies original data.
+
+Example:
+
+```javascript
+var ajv = new Ajv({ removeAdditional: true });
+var schema = {
+  "additionalProperties": false,
+  "properties": {
+    "foo": { "type": "number" },
+    "bar": {
+      "additionalProperties": { "type": "number" },
+      "properties": {
+        "baz": { "type": "string" }
+      }
+    }
+  }
+}
+
+var data = {
+  "foo": 0,
+  "additional1": 1, // will be removed; `additionalProperties` == false
+  "bar": {
+    "baz": "abc",
+    "additional2": 2 // will NOT be removed; `additionalProperties` != false
+  },
+}
+
+var validate = ajv.compile(schema);
+
+console.log(validate(data)); // true
+console.log(data); // { "foo": 0, "bar": { "baz": "abc", "additional2": 2 }
+```
+
+If `removeAdditional` option in the example above were `"all"` then both `additional1` and `additional2` properties would have been removed.
+
+If the option were `"failing"` then property `additional1` would have been removed regardless of its value and property `additional2` would have been removed only if its value were failing the schema in the inner `additionalProperties` (so in the example above it would have stayed because it passes the schema, but any non-number would have been removed).
+
+__Please note__: If you use `removeAdditional` option with `additionalProperties` keyword inside `anyOf`/`oneOf` keywords your validation can fail with this schema, for example:
+
+```json
+{
+  "type": "object",
+  "oneOf": [
+    {
+      "properties": {
+        "foo": { "type": "string" }
+      },
+      "required": [ "foo" ],
+      "additionalProperties": false
+    },
+    {
+      "properties": {
+        "bar": { "type": "integer" }
+      },
+      "required": [ "bar" ],
+      "additionalProperties": false
+    }
+  ]
+}
+```
+
+The intention of the schema above is to allow objects with either the string property "foo" or the integer property "bar", but not with both and not with any other properties.
+
+With the option `removeAdditional: true` the validation will pass for the object `{ "foo": "abc"}` but will fail for the object `{"bar": 1}`. It happens because while the first subschema in `oneOf` is validated, the property `bar` is removed because it is an additional property according to the standard (because it is not included in `properties` keyword in the same schema).
+
+While this behaviour is unexpected (issues [#129](https://github.com/epoberezkin/ajv/issues/129), [#134](https://github.com/epoberezkin/ajv/issues/134)), it is correct. To have the expected behaviour (both objects are allowed and additional properties are removed) the schema has to be refactored in this way:
+
+```json
+{
+  "type": "object",
+  "properties": {
+    "foo": { "type": "string" },
+    "bar": { "type": "integer" }
+  },
+  "additionalProperties": false,
+  "oneOf": [
+    { "required": [ "foo" ] },
+    { "required": [ "bar" ] }
+  ]
+}
+```
+
+The schema above is also more efficient - it will compile into a faster function.
+
+
+## Assigning defaults
+
+With [option `useDefaults`](#options) Ajv will assign values from `default` keyword in the schemas of `properties` and `items` (when it is the array of schemas) to the missing properties and items.
+
+This option modifies original data.
+
+__Please note__: by default the default value is inserted in the generated validation code as a literal (starting from v4.0), so the value inserted in the data will be the deep clone of the default in the schema.
+
+If you need to insert the default value in the data by reference pass the option `useDefaults: "shared"`.
+
+Inserting defaults by reference can be faster (in case you have an object in `default`) and it allows to have dynamic values in defaults, e.g. timestamp, without recompiling the schema. The side effect is that modifying the default value in any validated data instance will change the default in the schema and in other validated data instances. See example 3 below.
+
+
+Example 1 (`default` in `properties`):
+
+```javascript
+var ajv = new Ajv({ useDefaults: true });
+var schema = {
+  "type": "object",
+  "properties": {
+    "foo": { "type": "number" },
+    "bar": { "type": "string", "default": "baz" }
+  },
+  "required": [ "foo", "bar" ]
+};
+
+var data = { "foo": 1 };
+
+var validate = ajv.compile(schema);
+
+console.log(validate(data)); // true
+console.log(data); // { "foo": 1, "bar": "baz" }
+```
+
+Example 2 (`default` in `items`):
+
+```javascript
+var schema = {
+  "type": "array",
+  "items": [
+    { "type": "number" },
+    { "type": "string", "default": "foo" }
+  ]
+}
+
+var data = [ 1 ];
+
+var validate = ajv.compile(schema);
+
+console.log(validate(data)); // true
+console.log(data); // [ 1, "foo" ]
+```
+
+Example 3 (inserting "defaults" by reference):
+
+```javascript
+var ajv = new Ajv({ useDefaults: 'shared' });
+
+var schema = {
+  properties: {
+    foo: {
+      default: { bar: 1 }
+    }
+  }
+}
+
+var validate = ajv.compile(schema);
+
+var data = {};
+console.log(validate(data)); // true
+console.log(data); // { foo: { bar: 1 } }
+
+data.foo.bar = 2;
+
+var data2 = {};
+console.log(validate(data2)); // true
+console.log(data2); // { foo: { bar: 2 } }
+```
+
+`default` keywords in other cases are ignored:
+
+- not in `properties` or `items` subschemas
+- in schemas inside `anyOf`, `oneOf` and `not` (see [#42](https://github.com/epoberezkin/ajv/issues/42))
+- in `if` subschema of `switch` keyword
+- in schemas generated by custom macro keywords
+
+
+## Coercing data types
+
+When you are validating user inputs all your data properties are usually strings. The option `coerceTypes` allows you to have your data types coerced to the types specified in your schema `type` keywords, both to pass the validation and to use the correctly typed data afterwards.
+
+This option modifies original data.
+
+__Please note__: if you pass a scalar value to the validating function its type will be coerced and it will pass the validation, but the value of the variable you pass won't be updated because scalars are passed by value.
+
+
+Example 1:
+
+```javascript
+var ajv = new Ajv({ coerceTypes: true });
+var schema = {
+  "type": "object",
+  "properties": {
+    "foo": { "type": "number" },
+    "bar": { "type": "boolean" }
+  },
+  "required": [ "foo", "bar" ]
+};
+
+var data = { "foo": "1", "bar": "false" };
+
+var validate = ajv.compile(schema);
+
+console.log(validate(data)); // true
+console.log(data); // { "foo": 1, "bar": false }
+```
+
+Example 2 (array coercions):
+
+```javascript
+var ajv = new Ajv({ coerceTypes: 'array' });
+var schema = {
+  "properties": {
+    "foo": { "type": "array", "items": { "type": "number" } },
+    "bar": { "type": "boolean" }
+  }
+};
+
+var data = { "foo": "1", "bar": ["false"] };
+
+var validate = ajv.compile(schema);
+
+console.log(validate(data)); // true
+console.log(data); // { "foo": [1], "bar": false }
+```
+
+The coercion rules, as you can see from the example, are different from JavaScript both to validate user input as expected and to have the coercion reversible (to correctly validate cases where different types are defined in subschemas of "anyOf" and other compound keywords).
+
+See [Coercion rules](https://github.com/epoberezkin/ajv/blob/master/COERCION.md) for details.
+
+
+## API
+
+##### new Ajv(Object options) -&gt; Object
+
+Create Ajv instance.
+
+
+##### .compile(Object schema) -&gt; Function&lt;Object data&gt;
+
+Generate validating function and cache the compiled schema for future use.
+
+Validating function returns boolean and has properties `errors` with the errors from the last validation (`null` if there were no errors) and `schema` with the reference to the original schema.
+
+Unless the option `validateSchema` is false, the schema will be validated against meta-schema and if schema is invalid the error will be thrown. See [options](#options).
+
+
+##### <a name="api-compileAsync"></a>.compileAsync(Object schema [, Boolean meta] [, Function callback]) -&gt; Promise
+
+Asynchronous version of `compile` method that loads missing remote schemas using asynchronous function in `options.loadSchema`. This function returns a Promise that resolves to a validation function. An optional callback passed to `compileAsync` will be called with 2 parameters: error (or null) and validating function. The returned promise will reject (and the callback will be called with an error) when:
+
+- missing schema can't be loaded (`loadSchema` returns a Promise that rejects).
+- a schema containing a missing reference is loaded, but the reference cannot be resolved.
+- schema (or some loaded/referenced schema) is invalid.
+
+The function compiles schema and loads the first missing schema (or meta-schema) until all missing schemas are loaded.
+
+You can asynchronously compile meta-schema by passing `true` as the second parameter.
+
+See example in [Asynchronous compilation](#asynchronous-schema-compilation).
+
+
+##### .validate(Object schema|String key|String ref, data) -&gt; Boolean
+
+Validate data using passed schema (it will be compiled and cached).
+
+Instead of the schema you can use the key that was previously passed to `addSchema`, the schema id if it was present in the schema or any previously resolved reference.
+
+Validation errors will be available in the `errors` property of Ajv instance (`null` if there were no errors).
+
+__Please note__: every time this method is called the errors are overwritten so you need to copy them to another variable if you want to use them later.
+
+If the schema is asynchronous (has `$async` keyword on the top level) this method returns a Promise. See [Asynchronous validation](#asynchronous-validation).
+
+
+##### .addSchema(Array&lt;Object&gt;|Object schema [, String key]) -&gt; Ajv
+
+Add schema(s) to validator instance. This method does not compile schemas (but it still validates them). Because of that dependencies can be added in any order and circular dependencies are supported. It also prevents unnecessary compilation of schemas that are containers for other schemas but not used as a whole.
+
+Array of schemas can be passed (schemas should have ids), the second parameter will be ignored.
+
+Key can be passed that can be used to reference the schema and will be used as the schema id if there is no id inside the schema. If the key is not passed, the schema id will be used as the key.
+
+
+Once the schema is added, it (and all the references inside it) can be referenced in other schemas and used to validate data.
+
+Although `addSchema` does not compile schemas, explicit compilation is not required - the schema will be compiled when it is used first time.
+
+By default the schema is validated against meta-schema before it is added, and if the schema does not pass validation the exception is thrown. This behaviour is controlled by `validateSchema` option.
+
+__Please note__: Ajv uses the [method chaining syntax](https://en.wikipedia.org/wiki/Method_chaining) for all methods with the prefix `add*` and `remove*`.
+This allows you to do nice things like the following.
+
+```javascript
+var validate = new Ajv().addSchema(schema).addFormat(name, regex).getSchema(uri);
+```  
+
+##### .addMetaSchema(Array&lt;Object&gt;|Object schema [, String key]) -&gt; Ajv
+
+Adds meta schema(s) that can be used to validate other schemas. That function should be used instead of `addSchema` because there may be instance options that would compile a meta schema incorrectly (at the moment it is `removeAdditional` option).
+
+There is no need to explicitly add draft 6 meta schema (http://json-schema.org/draft-06/schema and http://json-schema.org/schema) - it is added by default, unless option `meta` is set to `false`. You only need to use it if you have a changed meta-schema that you want to use to validate your schemas. See `validateSchema`.
+
+
+##### <a name="api-validateschema"></a>.validateSchema(Object schema) -&gt; Boolean
+
+Validates schema. This method should be used to validate schemas rather than `validate` due to the inconsistency of `uri` format in JSON Schema standard.
+
+By default this method is called automatically when the schema is added, so you rarely need to use it directly.
+
+If schema doesn't have `$schema` property, it is validated against draft 6 meta-schema (option `meta` should not be false).
+
+If schema has `$schema` property, then the schema with this id (that should be previously added) is used to validate passed schema.
+
+Errors will be available at `ajv.errors`.
+
+
+##### .getSchema(String key) -&gt; Function&lt;Object data&gt;
+
+Retrieve compiled schema previously added with `addSchema` by the key passed to `addSchema` or by its full reference (id). The returned validating function has `schema` property with the reference to the original schema.
+
+
+##### .removeSchema([Object schema|String key|String ref|RegExp pattern]) -&gt; Ajv
+
+Remove added/cached schema. Even if schema is referenced by other schemas it can be safely removed as dependent schemas have local references.
+
+Schema can be removed using:
+- key passed to `addSchema`
+- it's full reference (id)
+- RegExp that should match schema id or key (meta-schemas won't be removed)
+- actual schema object that will be stable-stringified to remove schema from cache
+
+If no parameter is passed all schemas but meta-schemas will be removed and the cache will be cleared.
+
+
+##### <a name="api-addformat"></a>.addFormat(String name, String|RegExp|Function|Object format) -&gt; Ajv
+
+Add custom format to validate strings or numbers. It can also be used to replace pre-defined formats for Ajv instance.
+
+Strings are converted to RegExp.
+
+Function should return validation result as `true` or `false`.
+
+If object is passed it should have properties `validate`, `compare` and `async`:
+
+- _validate_: a string, RegExp or a function as described above.
+- _compare_: an optional comparison function that accepts two strings and compares them according to the format meaning. This function is used with keywords `formatMaximum`/`formatMinimum` (defined in [ajv-keywords](https://github.com/epoberezkin/ajv-keywords) package). It should return `1` if the first value is bigger than the second value, `-1` if it is smaller and `0` if it is equal.
+- _async_: an optional `true` value if `validate` is an asynchronous function; in this case it should return a promise that resolves with a value `true` or `false`.
+- _type_: an optional type of data that the format applies to. It can be `"string"` (default) or `"number"` (see https://github.com/epoberezkin/ajv/issues/291#issuecomment-259923858). If the type of data is different, the validation will pass.
+
+Custom formats can be also added via `formats` option.
+
+
+##### <a name="api-addkeyword"></a>.addKeyword(String keyword, Object definition) -&gt; Ajv
+
+Add custom validation keyword to Ajv instance.
+
+Keyword should be different from all standard JSON schema keywords and different from previously defined keywords. There is no way to redefine keywords or to remove keyword definition from the instance.
+
+Keyword must start with a letter, `_` or `$`, and may continue with letters, numbers, `_`, `$`, or `-`.
+It is recommended to use an application-specific prefix for keywords to avoid current and future name collisions.
+
+Example Keywords:
+- `"xyz-example"`: valid, and uses prefix for the xyz project to avoid name collisions.
+- `"example"`: valid, but not recommended as it could collide with future versions of JSON schema etc.
+- `"3-example"`: invalid as numbers are not allowed to be the first character in a keyword
+
+Keyword definition is an object with the following properties:
+
+- _type_: optional string or array of strings with data type(s) that the keyword applies to. If not present, the keyword will apply to all types.
+- _validate_: validating function
+- _compile_: compiling function
+- _macro_: macro function
+- _inline_: compiling function that returns code (as string)
+- _schema_: an optional `false` value used with "validate" keyword to not pass schema
+- _metaSchema_: an optional meta-schema for keyword schema
+- _modifying_: `true` MUST be passed if keyword modifies data
+- _valid_: pass `true`/`false` to pre-define validation result, the result returned from validation function will be ignored. This option cannot be used with macro keywords.
+- _$data_: an optional `true` value to support [$data reference](#data-reference) as the value of custom keyword. The reference will be resolved at validation time. If the keyword has meta-schema it would be extended to allow $data and it will be used to validate the resolved value. Supporting $data reference requires that keyword has validating function (as the only option or in addition to compile, macro or inline function).
+- _async_: an optional `true` value if the validation function is asynchronous (whether it is compiled or passed in _validate_ property); in this case it should return a promise that resolves with a value `true` or `false`. This option is ignored in case of "macro" and "inline" keywords.
+- _errors_: an optional boolean indicating whether keyword returns errors. If this property is not set Ajv will determine if the errors were set in case of failed validation.
+
+_compile_, _macro_ and _inline_ are mutually exclusive, only one should be used at a time. _validate_ can be used separately or in addition to them to support $data reference.
+
+__Please note__: If the keyword is validating data type that is different from the type(s) in its definition, the validation function will not be called (and expanded macro will not be used), so there is no need to check for data type inside validation function or inside schema returned by macro function (unless you want to enforce a specific type and for some reason do not want to use a separate `type` keyword for that). In the same way as standard keywords work, if the keyword does not apply to the data type being validated, the validation of this keyword will succeed.
+
+See [Defining custom keywords](#defining-custom-keywords) for more details.
+
+
+##### .getKeyword(String keyword) -&gt; Object|Boolean
+
+Returns custom keyword definition, `true` for pre-defined keywords and `false` if the keyword is unknown.
+
+
+##### .removeKeyword(String keyword) -&gt; Ajv
+
+Removes custom or pre-defined keyword so you can redefine them.
+
+While this method can be used to extend pre-defined keywords, it can also be used to completely change their meaning - it may lead to unexpected results.
+
+__Please note__: schemas compiled before the keyword is removed will continue to work without changes. To recompile schemas use `removeSchema` method and compile them again.
+
+
+##### .errorsText([Array&lt;Object&gt; errors [, Object options]]) -&gt; String
+
+Returns the text with all errors in a String.
+
+Options can have properties `separator` (string used to separate errors, ", " by default) and `dataVar` (the variable name that dataPaths are prefixed with, "data" by default).
+
+

+```
+
+##### Validation and reporting options
+
+- _$data_: support [$data references](#data-reference). Draft 6 meta-schema that is added by default will be extended to allow them. If you want to use another meta-schema you need to use $dataMetaSchema method to add support for $data reference. See [API](#api).
+- _allErrors_: check all rules collecting all errors. Default is to return after the first error.
+- _verbose_: include the reference to the part of the schema (`schema` and `parentSchema`) and validated data in errors (false by default).
+- _jsonPointers_: set `dataPath` property of errors using [JSON Pointers](https://tools.ietf.org/html/rfc6901) instead of JavaScript property access notation.
+- _uniqueItems_: validate `uniqueItems` keyword (true by default).
+- _unicode_: calculate correct length of strings with unicode pairs (true by default). Pass `false` to use `.length` of strings that is faster, but gives "incorrect" lengths of strings with unicode pairs - each unicode pair is counted as two characters.
+- _format_: formats validation mode ('fast' by default). Pass 'full' for more correct and slow validation or `false` not to validate formats at all. E.g., 25:00:00 and 2015/14/33 will be invalid time and date in 'full' mode but it will be valid in 'fast' mode.
+- _formats_: an object with custom formats. Keys and values will be passed to `addFormat` method.
+- _unknownFormats_: handling of unknown formats. Option values:
+  - `true` (default) - if an unknown format is encountered the exception is thrown during schema compilation. If `format` keyword value is [$data reference](#data-reference) and it is unknown the validation will fail.
+  - `[String]` - an array of unknown format names that will be ignored. This option can be used to allow usage of third party schemas with format(s) for which you don't have definitions, but still fail if another unknown format is used. If `format` keyword value is [$data reference](#data-reference) and it is not in this array the validation will fail.
+  - `"ignore"` - to log warning during schema compilation and always pass validation (the default behaviour in versions before 5.0.0). This option is not recommended, as it allows to mistype format name and it won't be validated without any error message. This behaviour is required by JSON-schema specification.
+- _schemas_: an array or object of schemas that will be added to the instance. In case you pass the array the schemas must have IDs in them. When the object is passed the method `addSchema(value, key)` will be called for each schema in this object.
+- _logger_: sets the logging method. Default is the global `console` object that should have methods `log`, `warn` and `error`. Option values:
+  - custom logger - it should have methods `log`, `warn` and `error`. If any of these methods is missing an exception will be thrown.
+  - `false` - logging is disabled.
+
+
+##### Referenced schema options
+
+- _schemaId_: this option defines which keywords are used as schema URI. Option value:
+  - `"$id"` (recommended) - only use `$id` keyword as schema URI (as specified in JSON Schema draft-06), ignore `id` keyword (if it is present a warning will be logged).
+  - `"id"` - only use `id` keyword as schema URI (as specified in JSON Schema draft-04), ignore `$id` keyword (if it is present a warning will be logged).
+  - `undefined` (default) - use both `$id` and `id` keywords as schema URI. If both are present (in the same schema object) and different the exception will be thrown during schema compilation.
+- _missingRefs_: handling of missing referenced schemas. Option values:
+  - `true` (default) - if the reference cannot be resolved during compilation the exception is thrown. The thrown error has properties `missingRef` (with hash fragment) and `missingSchema` (without it). Both properties are resolved relative to the current base id (usually schema id, unless it was substituted).
+  - `"ignore"` - to log error during compilation and always pass validation.
+  - `"fail"` - to log error and successfully compile schema but fail validation if this rule is checked.
+- _extendRefs_: validation of other keywords when `$ref` is present in the schema. Option values:
+  - `"ignore"` (default) - when `$ref` is used other keywords are ignored (as per [JSON Reference](https://tools.ietf.org/html/draft-pbryan-zyp-json-ref-03#section-3) standard). A warning will be logged during the schema compilation.
+  - `"fail"` (recommended) - if other validation keywords are used together with `$ref` the exception will be thrown when the schema is compiled. This option is recommended to make sure schema has no keywords that are ignored, which can be confusing.
+  - `true` - validate all keywords in the schemas with `$ref` (the default behaviour in versions before 5.0.0).
+- _loadSchema_: asynchronous function that will be used to load remote schemas when `compileAsync` [method](#api-compileAsync) is used and some reference is missing (option `missingRefs` should NOT be 'fail' or 'ignore'). This function should accept remote schema uri as a parameter and return a Promise that resolves to a schema. See example in [Asynchronous compilation](#asynchronous-schema-compilation).
+
+
+##### Options to modify validated data
+
+- _removeAdditional_: remove additional properties - see example in [Filtering data](#filtering-data). This option is not used if schema is added with `addMetaSchema` method. Option values:
+  - `false` (default) - not to remove additional properties
+  - `"all"` - all additional properties are removed, regardless of `additionalProperties` keyword in schema (and no validation is made for them).
+  - `true` - only additional properties with `additionalProperties` keyword equal to `false` are removed.
+  - `"failing"` - additional properties that fail schema validation will be removed (where `additionalProperties` keyword is `false` or schema).
+- _useDefaults_: replace missing properties and items with the values from corresponding `default` keywords. Default behaviour is to ignore `default` keywords. This option is not used if schema is added with `addMetaSchema` method. See examples in [Assigning defaults](#assigning-defaults). Option values:
+  - `false` (default) - do not use defaults
+  - `true` - insert defaults by value (safer and slower, object literal is used).
+  - `"shared"` - insert defaults by reference (faster). If the default is an object, it will be shared by all instances of validated data. If you modify the inserted default in the validated data, it will be modified in the schema as well.
+- _coerceTypes_: change data type of data to match `type` keyword. See the example in [Coercing data types](#coercing-data-types) and [coercion rules](https://github.com/epoberezkin/ajv/blob/master/COERCION.md). Option values:
+  - `false` (default) - no type coercion.
+  - `true` - coerce scalar data types.
+  - `"array"` - in addition to coercions between scalar types, coerce scalar data to an array with one element and vice versa (as required by the schema).
+
+
+##### Asynchronous validation options
+
+- _async_: determines how Ajv compiles asynchronous schemas (see [Asynchronous validation](#asynchronous-validation)) to functions. Option values:
+  - `"*"` / `"co*"` (default) - compile to generator function ("co*" - wrapped with `co.wrap`). If generators are not supported and you don't provide `processCode` option (or `transpile` option if you use [ajv-async](https://github.com/epoberezkin/ajv-async) package), the exception will be thrown when async schema is compiled.
+  - `"es7"` - compile to es7 async function. Unless your platform supports them you need to provide `processCode` or `transpile` option. According to [compatibility table](http://kangax.github.io/compat-table/es7/)) async functions are supported by:
+    - Firefox 52,
+    - Chrome 55,
+    - Node.js 7 (with `--harmony-async-await`),
+    - MS Edge 13 (with flag).
+  - `undefined`/`true` - auto-detect async mode. It requires [ajv-async](https://github.com/epoberezkin/ajv-async) package. If `transpile` option is not passed, ajv-async will choose the first of supported/installed async/transpile modes in this order:
+    - "es7" (native async functions),
+    - "co*" (native generators with co.wrap),
+    - "es7"/"nodent",
+    - "co*"/"regenerator" during the creation of the Ajv instance.
+
+  If none of the options is available the exception will be thrown.
+- _transpile_: Requires [ajv-async](https://github.com/epoberezkin/ajv-async) package. It determines whether Ajv transpiles compiled asynchronous validation function. Option values:
+  - `"nodent"` - transpile with [nodent](https://github.com/MatAtBread/nodent). If nodent is not installed, the exception will be thrown. nodent can only transpile es7 async functions; it will enforce this mode.
+  - `"regenerator"` - transpile with [regenerator](https://github.com/facebook/regenerator). If regenerator is not installed, the exception will be thrown.
+  - a function - this function should accept the code of validation function as a string and return transpiled code. This option allows you to use any other transpiler you prefer. If you are passing a function, you can simply pass it to `processCode` option without using ajv-async.
+
+
+##### Advanced options
+
+- _meta_: add [meta-schema](http://json-schema.org/documentation.html) so it can be used by other schemas (true by default). If an object is passed, it will be used as the default meta-schema for schemas that have no `$schema` keyword. This default meta-schema MUST have `$schema` keyword.
+- _validateSchema_: validate added/compiled schemas against meta-schema (true by default). `$schema` property in the schema can either be http://json-schema.org/schema or http://json-schema.org/draft-04/schema or absent (draft-4 meta-schema will be used) or can be a reference to the schema previously added with `addMetaSchema` method. Option values:
+  - `true` (default) -  if the validation fails, throw the exception.
+  - `"log"` - if the validation fails, log error.
+  - `false` - skip schema validation.
+- _addUsedSchema_: by default methods `compile` and `validate` add schemas to the instance if they have `$id` (or `id`) property that doesn't start with "#". If `$id` is present and it is not unique the exception will be thrown. Set this option to `false` to skip adding schemas to the instance and the `$id` uniqueness check when these methods are used. This option does not affect `addSchema` method.
+- _inlineRefs_: Affects compilation of referenced schemas. Option values:
+  - `true` (default) - the referenced schemas that don't have refs in them are inlined, regardless of their size - that substantially improves performance at the cost of the bigger size of compiled schema functions.
+  - `false` - to not inline referenced schemas (they will be compiled as separate functions).
+  - integer number - to limit the maximum number of keywords of the schema that will be inlined.
+- _passContext_: pass validation context to custom keyword functions. If this option is `true` and you pass some context to the compiled validation function with `validate.call(context, data)`, the `context` will be available as `this` in your custom keywords. By default `this` is Ajv instance.
+- _loopRequired_: by default `required` keyword is compiled into a single expression (or a sequence of statements in `allErrors` mode). In case of a very large number of properties in this keyword it may result in a very big validation function. Pass integer to set the number of properties above which `required` keyword will be validated in a loop - smaller validation function size but also worse performance.
+- _ownProperties_: by default Ajv iterates over all enumerable object properties; when this option is `true` only own enumerable object properties (i.e. found directly on the object rather than on its prototype) are iterated. Contributed by @mbroadst.
+- _multipleOfPrecision_: by default `multipleOf` keyword is validated by comparing the result of division with parseInt() of that result. It works for dividers that are bigger than 1. For small dividers such as 0.01 the result of the division is usually not integer (even when it should be integer, see issue [#84](https://github.com/epoberezkin/ajv/issues/84)). If you need to use fractional dividers set this option to some positive integer N to have `multipleOf` validated using this formula: `Math.abs(Math.round(division) - division) < 1e-N` (it is slower but allows for float arithmetics deviations).
+- _errorDataPath_: set `dataPath` to point to 'object' (default) or to 'property' when validating keywords `required`, `additionalProperties` and `dependencies`.
+- _messages_: Include human-readable messages in errors. `true` by default. `false` can be passed when custom messages are used (e.g. with [ajv-i18n](https://github.com/epoberezkin/ajv-i18n)).
+- _sourceCode_: add `sourceCode` property to validating function (for debugging; this code can be different from the result of toString call).
+- _processCode_: an optional function to process generated code before it is passed to Function constructor. It can be used to either beautify (the validating function is generated without line-breaks) or to transpile code. Starting from version 5.0.0 this option replaced options:
+  - `beautify` that formatted the generated function using [js-beautify](https://github.com/beautify-web/js-beautify). If you want to beautify the generated code pass `require('js-beautify').js_beautify`.
+  - `transpile` that transpiled asynchronous validation function. You can still use `transpile` option with [ajv-async](https://github.com/epoberezkin/ajv-async) package. See [Asynchronous validation](#asynchronous-validation) for more information.
+- _cache_: an optional instance of cache to store compiled schemas using stable-stringified schema as a key. For example, set-associative cache [sacjs](https://github.com/epoberezkin/sacjs) can be used. If not passed then a simple hash is used which is good enough for the common use case (a limited number of statically defined schemas). Cache should have methods `put(key, value)`, `get(key)`, `del(key)` and `clear()`.
+- _serialize_: an optional function to serialize schema to cache key. Pass `false` to use schema itself as a key (e.g., if WeakMap used as a cache). By default [fast-json-stable-stringify](https://github.com/epoberezkin/fast-json-stable-stringify) is used.
+
+
+## Validation errors
+
+In case of validation failure, Ajv assigns the array of errors to `errors` property of validation function (or to `errors` property of Ajv instance when `validate` or `validateSchema` methods were called). In case of [asynchronous validation](#asynchronous-validation), the returned promise is rejected with exception `Ajv.ValidationError` that has `errors` property.
+
+
+### Error objects
+
+Each error is an object with the following properties:
+
+- _keyword_: validation keyword.
+- _dataPath_: the path to the part of the data that was validated. By default `dataPath` uses JavaScript property access notation (e.g., `".prop[1].subProp"`). When the option `jsonPointers` is true (see [Options](#options)) `dataPath` will be set using JSON pointer standard (e.g., `"/prop/1/subProp"`).
+- _schemaPath_: the path (JSON-pointer as a URI fragment) to the schema of the keyword that failed validation.
+- _params_: the object with the additional information about error that can be used to create custom error messages (e.g., using [ajv-i18n](https://github.com/epoberezkin/ajv-i18n) package). See below for parameters set by all keywords.
+- _message_: the standard error message (can be excluded with option `messages` set to false).
+- _schema_: the schema of the keyword (added with `verbose` option).
+- _parentSchema_: the schema containing the keyword (added with `verbose` option)
+- _data_: the data validated by the keyword (added with `verbose` option).
+
+__Please note__: `propertyNames` keyword schema validation errors have an additional property `propertyName`, `dataPath` points to the object. After schema validation for each property name, if it is invalid an additional error is added with the property `keyword` equal to `"propertyNames"`.
+
+
+### Error parameters
+
+Properties of `params` object in errors depend on the keyword that failed validation.
+
+- `maxItems`, `minItems`, `maxLength`, `minLength`, `maxProperties`, `minProperties` - property `limit` (number, the schema of the keyword).
+- `additionalItems` - property `limit` (the maximum number of allowed items in case when `items` keyword is an array of schemas and `additionalItems` is false).
+- `additionalProperties` - property `additionalProperty` (the property not used in `properties` and `patternProperties` keywords).
+- `dependencies` - properties:
+  - `property` (dependent property),
+  - `missingProperty` (required missing dependency - only the first one is reported currently)
+  - `deps` (required dependencies, comma separated list as a string),
+  - `depsCount` (the number of required dependencies).
+- `format` - property `format` (the schema of the keyword).
+- `maximum`, `minimum` - properties:
+  - `limit` (number, the schema of the keyword),
+  - `exclusive` (boolean, the schema of `exclusiveMaximum` or `exclusiveMinimum`),
+  - `comparison` (string, comparison operation to compare the data to the limit, with the data on the left and the limit on the right; can be "<", "<=", ">", ">=")
+- `multipleOf` - property `multipleOf` (the schema of the keyword)
+- `pattern` - property `pattern` (the schema of the keyword)
+- `required` - property `missingProperty` (required property that is missing).
+- `propertyNames` - property `propertyName` (an invalid property name).
+- `patternRequired` (in ajv-keywords) - property `missingPattern` (required pattern that did not match any property).
+- `type` - property `type` (required type(s), a string, can be a comma-separated list)
+- `uniqueItems` - properties `i` and `j` (indices of duplicate items).
+- `enum` - property `allowedValues` pointing to the array of values (the schema of the keyword).
+- `$ref` - property `ref` with the referenced schema URI.
+- custom keywords (in case keyword definition doesn't create errors) - property `keyword` (the keyword name).

+## Tests
+
+```
+npm install
+git submodule update --init
+npm test
+```
+
+## Contributing
+
+All validation functions are generated using doT templates in [dot](https://github.com/epoberezkin/ajv/tree/master/lib/dot) folder. Templates are precompiled so doT is not a run-time dependency.
+
+`npm run build` - compiles templates to [dotjs](https://github.com/epoberezkin/ajv/tree/master/lib/dotjs) folder.
+
+`npm run watch` - automatically compiles templates when files in dot folder change
+

+
+## FAQ
+
+### Why do you test for codes not in the ECMA 48 standard?
+
+Some of the codes we run as a test are codes that we acquired finding various lists of non-standard or manufacturer specific codes. If I recall correctly, we test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them.
+
+On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out.

+# ansi-styles [![Build Status](https://travis-ci.org/chalk/ansi-styles.svg?branch=master)](https://travis-ci.org/chalk/ansi-styles)
+
+> [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
+
+You probably want the higher-level [chalk](https://github.com/chalk/chalk) module for styling your strings.
+
+![](screenshot.png)
+
+
+## Install
+
+```
+$ npm install --save ansi-styles
+```
+
+
+## Usage
+
+```js
+var ansi = require('ansi-styles');
+
+console.log(ansi.green.open + 'Hello world!' + ansi.green.close);
+```
+
+
+## API
+
+Each style has an `open` and `close` property.
+
+
+## Styles
+
+### Modifiers
+
+- `reset`
+- `bold`
+- `dim`
+- `italic` *(not widely supported)*
+- `underline`
+- `inverse`
+- `hidden`
+- `strikethrough` *(not widely supported)*
+
+### Colors
+
+- `black`
+- `red`
+- `green`
+- `yellow`
+- `blue`
+- `magenta`
+- `cyan`
+- `white`
+- `gray`
+
+### Background colors
+
+- `bgBlack`
+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`
+
+
+## Advanced usage
+
+By default you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
+
+- `ansi.modifiers`
+- `ansi.colors`
+- `ansi.bgColors`
+
+
+###### Example
+
+```js
+console.log(ansi.colors.green.open);
+```

+argparse
+========
+
+[![Build Status](https://secure.travis-ci.org/nodeca/argparse.png?branch=master)](http://travis-ci.org/nodeca/argparse)
+[![NPM version](https://img.shields.io/npm/v/argparse.svg)](https://www.npmjs.org/package/argparse)
+
+CLI arguments parser for node.js. Javascript port of python's
+[argparse](http://docs.python.org/dev/library/argparse.html) module
+(original version 3.2). That's a full port, except some very rare options,
+recorded in issue tracker.
+
+**NB. Difference with original.**
+
+- Method names changed to camelCase. See [generated docs](http://nodeca.github.com/argparse/).
+- Use `defaultValue` instead of `default`.
+
+
+Example
+=======
+
+test.js file:
+
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse example'
+});
+parser.addArgument(
+  [ '-f', '--foo' ],
+  {
+    help: 'foo bar'
+  }
+);
+parser.addArgument(
+  [ '-b', '--bar' ],
+  {
+    help: 'bar foo'
+  }
+);
+parser.addArgument(
+  '--baz',
+  {
+    help: 'baz bar'
+  }
+);
+var args = parser.parseArgs();
+console.dir(args);
+```
+
+Display help:
+
+```
+$ ./test.js -h
+usage: example.js [-h] [-v] [-f FOO] [-b BAR] [--baz BAZ]
+
+Argparse example
+
+Optional arguments:
+  -h, --help         Show this help message and exit.
+  -v, --version      Show program's version number and exit.
+  -f FOO, --foo FOO  foo bar
+  -b BAR, --bar BAR  bar foo
+  --baz BAZ          baz bar
+```
+
+Parse arguments:
+
+```
+$ ./test.js -f=3 --bar=4 --baz 5
+{ foo: '3', bar: '4', baz: '5' }
+```
+
+More [examples](https://github.com/nodeca/argparse/tree/master/examples).
+
+
+ArgumentParser objects
+======================
+
+```
+new ArgumentParser({paramters hash});
+```
+
+Creates a new ArgumentParser object.
+
+**Supported params:**
+
+- ```description``` - Text to display before the argument help.
+- ```epilog``` - Text to display after the argument help.
+- ```addHelp``` - Add a -h/–help option to the parser. (default: true)
+- ```argumentDefault``` - Set the global default value for arguments. (default: null)
+- ```parents``` - A list of ArgumentParser objects whose arguments should also be included.
+- ```prefixChars``` - The set of characters that prefix optional arguments. (default: ‘-‘)
+- ```formatterClass``` - A class for customizing the help output.
+- ```prog``` - The name of the program (default: `path.basename(process.argv[1])`)
+- ```usage``` - The string describing the program usage (default: generated)
+- ```conflictHandler``` - Usually unnecessary, defines strategy for resolving conflicting optionals.
+
+**Not supportied yet**
+
+- ```fromfilePrefixChars``` - The set of characters that prefix files from which additional arguments should be read.
+
+
+Details in [original ArgumentParser guide](http://docs.python.org/dev/library/argparse.html#argumentparser-objects)
+
+
+addArgument() method
+====================
+
+```
+ArgumentParser.addArgument(name or flag or [name] or [flags...], {options})
+```
+
+Defines how a single command-line argument should be parsed.
+
+- ```name or flag or [name] or [flags...]``` - Either a positional name
+  (e.g., `'foo'`), a single option (e.g., `'-f'` or `'--foo'`), an array
+  of a single positional name (e.g., `['foo']`), or an array of options
+  (e.g., `['-f', '--foo']`).
+
+Options:
+
+- ```action``` - The basic type of action to be taken when this argument is encountered at the command line.
+- ```nargs```- The number of command-line arguments that should be consumed.
+- ```constant``` - A constant value required by some action and nargs selections.
+- ```defaultValue``` - The value produced if the argument is absent from the command line.
+- ```type``` - The type to which the command-line argument should be converted.
+- ```choices``` - A container of the allowable values for the argument.
+- ```required``` - Whether or not the command-line option may be omitted (optionals only).
+- ```help``` - A brief description of what the argument does.
+- ```metavar``` - A name for the argument in usage messages.
+- ```dest``` - The name of the attribute to be added to the object returned by parseArgs().
+
+Details in [original add_argument guide](http://docs.python.org/dev/library/argparse.html#the-add-argument-method)
+
+
+Action (some details)
+================
+
+ArgumentParser objects associate command-line arguments with actions.
+These actions can do just about anything with the command-line arguments associated
+with them, though most actions simply add an attribute to the object returned by
+parseArgs(). The action keyword argument specifies how the command-line arguments
+should be handled. The supported actions are:
+
+- ```store``` - Just stores the argument’s value. This is the default action.
+- ```storeConst``` - Stores value, specified by the const keyword argument.
+  (Note that the const keyword argument defaults to the rather unhelpful None.)
+  The 'storeConst' action is most commonly used with optional arguments, that
+  specify some sort of flag.
+- ```storeTrue``` and ```storeFalse``` - Stores values True and False
+  respectively. These are special cases of 'storeConst'.
+- ```append``` - Stores a list, and appends each argument value to the list.
+  This is useful to allow an option to be specified multiple times.
+- ```appendConst``` - Stores a list, and appends value, specified by the
+  const keyword argument to the list. (Note, that the const keyword argument defaults
+  is None.) The 'appendConst' action is typically used when multiple arguments need
+  to store constants to the same list.
+- ```count``` - Counts the number of times a keyword argument occurs. For example,
+  used for increasing verbosity levels.
+- ```help``` - Prints a complete help message for all the options in the current
+  parser and then exits. By default a help action is automatically added to the parser.
+  See ArgumentParser for details of how the output is created.
+- ```version``` - Prints version information and exit. Expects a `version=`
+  keyword argument in the addArgument() call.
+
+Details in [original action guide](http://docs.python.org/dev/library/argparse.html#action)
+
+
+Sub-commands
+============
+
+ArgumentParser.addSubparsers()
+
+Many programs split their functionality into a number of sub-commands, for
+example, the svn program can invoke sub-commands like `svn checkout`, `svn update`,
+and `svn commit`. Splitting up functionality this way can be a particularly good
+idea when a program performs several different functions which require different
+kinds of command-line arguments. `ArgumentParser` supports creation of such
+sub-commands with `addSubparsers()` method. The `addSubparsers()` method is
+normally called with no arguments and returns an special action object.
+This object has a single method `addParser()`, which takes a command name and
+any `ArgumentParser` constructor arguments, and returns an `ArgumentParser` object
+that can be modified as usual.
+
+Example:
+
+sub_commands.js
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse examples: sub-commands',
+});
+
+var subparsers = parser.addSubparsers({
+  title:'subcommands',
+  dest:"subcommand_name"
+});
+
+var bar = subparsers.addParser('c1', {addHelp:true});
+bar.addArgument(
+  [ '-f', '--foo' ],
+  {
+    action: 'store',
+    help: 'foo3 bar3'
+  }
+);
+var bar = subparsers.addParser(
+  'c2',
+  {aliases:['co'], addHelp:true}
+);
+bar.addArgument(
+  [ '-b', '--bar' ],
+  {
+    action: 'store',
+    type: 'int',
+    help: 'foo3 bar3'
+  }
+);
+
+var args = parser.parseArgs();
+console.dir(args);
+
+```

+
+## Options
+
+### `highlightCode`
+
+`boolean`, defaults to `false`.
+
+Toggles syntax highlighting the code as JavaScript for terminals.
+
+### `linesAbove`
+
+`number`, defaults to `2`.
+
+Adjust the number of lines to show above the error.
+
+### `linesBelow`
+
+`number`, defaults to `3`.
+
+Adjust the number of lines to show below the error.
+
+### `forceColor`
+
+`boolean`, defaults to `false`.
+
+Enable this to forcibly syntax highlight the code as JavaScript (for non-terminals); overrides `highlightCode`.

+> Terminal string styling done right
+
+[![Build Status](https://travis-ci.org/chalk/chalk.svg?branch=master)](https://travis-ci.org/chalk/chalk)
+[![Coverage Status](https://coveralls.io/repos/chalk/chalk/badge.svg?branch=master)](https://coveralls.io/r/chalk/chalk?branch=master)
+[![](http://img.shields.io/badge/unicorn-approved-ff69b4.svg)](https://www.youtube.com/watch?v=9auOCbH5Ns4)
+
+
+[colors.js](https://github.com/Marak/colors.js) used to be the most popular string styling module, but it has serious deficiencies like extending `String.prototype` which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68). Although there are other ones, they either do too much or not enough.
+
+**Chalk is a clean and focused alternative.**
+
+![](https://github.com/chalk/ansi-styles/raw/master/screenshot.png)
+
+
+## Why
+
+- Highly performant
+- Doesn't extend `String.prototype`
+- Expressive API
+- Ability to nest styles
+- Clean and focused
+- Auto-detects color support
+- Actively maintained
+- [Used by ~4500 modules](https://www.npmjs.com/browse/depended/chalk) as of July 15, 2015
+
+
+## Install
+
+```
+$ npm install --save chalk
+```
+
+
+## Usage
+
+Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
+
+```js
+var chalk = require('chalk');
+
+// style a string
+chalk.blue('Hello world!');
+
+// combine styled and normal strings
+chalk.blue('Hello') + 'World' + chalk.red('!');
+
+// compose multiple styles using the chainable API
+chalk.blue.bgRed.bold('Hello world!');
+
+// pass in multiple arguments
+chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz');
+
+// nest styles
+chalk.red('Hello', chalk.underline.bgBlue('world') + '!');
+
+// nest styles of the same type even (color, underline, background)
+chalk.green(
+	'I am a green line ' +
+	chalk.blue.underline.bold('with a blue substring') +
+	' that becomes green again!'
+);
+```
+
+Easily define your own themes.
+
+```js
+var chalk = require('chalk');
+var error = chalk.bold.red;
+console.log(error('Error!'));
+```
+
+Take advantage of console.log [string substitution](http://nodejs.org/docs/latest/api/console.html#console_console_log_data).
+
+```js
+var name = 'Sindre';
+console.log(chalk.green('Hello %s'), name);
+//=> Hello Sindre
+```
+
+
+## API
+
+### chalk.`<style>[.<style>...](string, [string...])`
+
+Example: `chalk.red.bold.underline('Hello', 'world');`
+
+Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that `Chalk.red.yellow.green` is equivalent to `Chalk.green`.
+
+Multiple arguments will be separated by space.
+
+### chalk.enabled
+
+Color support is automatically detected, but you can override it by setting the `enabled` property. You should however only do this in your own code as it applies globally to all chalk consumers.
+
+If you need to change this in a reusable module create a new instance:
+
+```js
+var ctx = new chalk.constructor({enabled: false});
+```
+
+### chalk.supportsColor
+
+Detect whether the terminal [supports color](https://github.com/chalk/supports-color). Used internally and handled for you, but exposed for convenience.
+
+Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, add an environment variable `FORCE_COLOR` with any value to force color. Trumps `--no-color`.
+
+### chalk.styles
+
+Exposes the styles as [ANSI escape codes](https://github.com/chalk/ansi-styles).
+
+Generally not useful, but you might need just the `.open` or `.close` escape code if you're mixing externally styled strings with your own.
+
+```js
+var chalk = require('chalk');
+
+console.log(chalk.styles.red);
+//=> {open: '\u001b[31m', close: '\u001b[39m'}
+
+console.log(chalk.styles.red.open + 'Hello' + chalk.styles.red.close);
+```
+
+### chalk.hasColor(string)
+
+Check whether a string [has color](https://github.com/chalk/has-ansi).
+
+### chalk.stripColor(string)
+
+[Strip color](https://github.com/chalk/strip-ansi) from a string.
+
+Can be useful in combination with `.supportsColor` to strip color on externally styled text when it's not supported.
+
+Example:
+
+```js
+var chalk = require('chalk');
+var styledString = getText();
+
+if (!chalk.supportsColor) {
+	styledString = chalk.stripColor(styledString);
+}
+```
+
+
+## Styles
+
+### Modifiers
+
+- `reset`
+- `bold`
+- `dim`
+- `italic` *(not widely supported)*
+- `underline`
+- `inverse`
+- `hidden`
+- `strikethrough` *(not widely supported)*
+
+### Colors
+
+- `black`
+- `red`
+- `green`
+- `yellow`
+- `blue` *(on Windows the bright version is used as normal blue is illegible)*
+- `magenta`
+- `cyan`
+- `white`
+- `gray`
+
+### Background colors
+
+- `bgBlack`
+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`
+
+
+## 256-colors
+
+Chalk does not support anything other than the base eight colors, which guarantees it will work on all terminals and systems. Some terminals, specifically `xterm` compliant ones, will support the full range of 8-bit colors. For this the lower level [ansi-256-colors](https://github.com/jbnicolai/ansi-256-colors) package can be used.
+
+
+## Windows
+
+If you're on Windows, do yourself a favor and use [`cmder`](http://bliker.github.io/cmder/) instead of `cmd.exe`.

+var balanced = require('balanced-match');
+
+console.log(balanced('{', '}', 'pre{in{nested}}post'));
+console.log(balanced('{', '}', 'pre{first}between{second}post'));
+console.log(balanced(/\s+\{\s+/, /\s+\}\s+/, 'pre  {   in{nest}   }  post'));
+```
+
+The matches are:
+
+```bash
+$ node example.js
+{ start: 3, end: 14, pre: 'pre', body: 'in{nested}', post: 'post' }
+{ start: 3,
+  end: 9,
+  pre: 'pre',
+  body: 'first',
+  post: 'between{second}post' }
+{ start: 3, end: 17, pre: 'pre', body: 'in{nest}', post: 'post' }
+```
+
+## API
+
+### var m = balanced(a, b, str)
+
+For the first non-nested matching pair of `a` and `b` in `str`, return an
+object with those keys:
+
+* **start** the index of the first match of `a`
+* **end** the index of the matching `b`
+* **pre** the preamble, `a` and `b` not included
+* **body** the match, `a` and `b` not included
+* **post** the postscript, `a` and `b` not included
+
+If there's no match, `undefined` will be returned.
+
+If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `['{', 'a', '']` and `{a}}` will match `['', 'a', '}']`.
+
+### var r = balanced.range(a, b, str)
+
+For the first non-nested matching pair of `a` and `b` in `str`, return an
+array with indexes: `[ <a index>, <b index> ]`.
+
+If there's no match, `undefined` will be returned.
+
+If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `[ 1, 3 ]` and `{a}}` will match `[0, 2]`.

+[Brace expansion](https://www.gnu.org/software/bash/manual/html_node/Brace-Expansion.html), 
+as known from sh/bash, in JavaScript.
+
+[![build status](https://secure.travis-ci.org/juliangruber/brace-expansion.svg)](http://travis-ci.org/juliangruber/brace-expansion)
+[![downloads](https://img.shields.io/npm/dm/brace-expansion.svg)](https://www.npmjs.org/package/brace-expansion)

+
+[![testling badge](https://ci.testling.com/juliangruber/brace-expansion.png)](https://ci.testling.com/juliangruber/brace-expansion)
+
+## Example
+
+```js
+var expand = require('brace-expansion');
+
+expand('file-{a,b,c}.jpg')
+// => ['file-a.jpg', 'file-b.jpg', 'file-c.jpg']
+
+expand('-v{,,}')
+// => ['-v', '-v', '-v']
+
+expand('file{0..2}.jpg')
+// => ['file0.jpg', 'file1.jpg', 'file2.jpg']
+
+expand('file-{a..c}.jpg')
+// => ['file-a.jpg', 'file-b.jpg', 'file-c.jpg']
+
+expand('file{2..0}.jpg')
+// => ['file2.jpg', 'file1.jpg', 'file0.jpg']
+
+expand('file{0..4..2}.jpg')
+// => ['file0.jpg', 'file2.jpg', 'file4.jpg']
+
+expand('file-{a..e..2}.jpg')
+// => ['file-a.jpg', 'file-c.jpg', 'file-e.jpg']
+
+expand('file{00..10..5}.jpg')
+// => ['file00.jpg', 'file05.jpg', 'file10.jpg']
+
+expand('{{A..C},{a..c}}')
+// => ['A', 'B', 'C', 'a', 'b', 'c']
+
+expand('ppp{,config,oe{,conf}}')
+// => ['ppp', 'pppconfig', 'pppoe', 'pppoeconf']
+```
+
+## API
+
+```js
+var expand = require('brace-expansion');
+```
+
+### var expanded = expand(str)
+
+Return an array of all possible and valid expansions of `str`. If none are
+found, `[str]` is returned.
+
+Valid expansions are:
+
+```js
+/^(.*,)+(.+)?$/
+// {a,b,...}
+```
+
+A comma seperated list of options, like `{a,b}` or `{a,{b,c}}` or `{,a,}`.
+
+```js
+/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
+// {x..y[..incr]}
+```
+
+A numeric sequence from `x` to `y` inclusive, with optional increment.
+If `x` or `y` start with a leading `0`, all the numbers will be padded
+to have equal length. Negative numbers and backwards iteration work too.
+
+```js
+/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
+// {x..y[..incr]}
+```
+
+An alphabetic sequence from `x` to `y` inclusive, with optional increment.
+`x` and `y` must be exactly one character, and if given, `incr` must be a
+number.
+
+For compatibility reasons, the string `${` is not eligible for brace expansion.
+

+
+> Get the path of the caller module
+
+You can't use [`module.parent`](http://nodejs.org/api/modules.html#modules_module_parent) as modules are cached and it will return the first caller module, not necessarily the current one.
+
+
+## Install
+
+```
+$ npm install --save caller-path
+```
+
+
+## Usage
+
+```js
+// foo.js
+var callerPath = require('caller-path');
+
+module.exports = function () {
+	console.log(callerPath());
+	//=> /Users/sindresorhus/dev/unicorn/bar.js
+}
+```
+
+```js
+// bar.js
+var foo = require('./foo');
+foo();

+# callsites [![Build Status](https://travis-ci.org/sindresorhus/callsites.svg?branch=master)](https://travis-ci.org/sindresorhus/callsites)
+
+> Get callsites from the [V8 stack trace API](https://code.google.com/p/v8/wiki/JavaScriptStackTraceApi)
+
+
+## Install
+
+```sh
+$ npm install --save callsites
+```
+
+
+## Usage
+
+```js
+var callsites = require('callsites');
+
+function unicorn() {
+	console.log(callsites()[0].getFileName());
+	//=> /Users/sindresorhus/dev/callsites/test.js
+}
+
+unicorn();
+```
+
+## API
+
+Returns an array of callsite objects with the following methods:
+
+- `getThis`: returns the value of this
+- `getTypeName`: returns the type of this as a string. This is the name of the function stored in the constructor field of this, if available, otherwise the object's [[Class]] internal property.
+- `getFunction`: returns the current function
+- `getFunctionName`: returns the name of the current function, typically its name property. If a name property is not available an attempt will be made to try to infer a name from the function's context.
+- `getMethodName`: returns the name of the property of this or one of its prototypes that holds the current function
+- `getFileName`: if this function was defined in a script returns the name of the script
+- `getLineNumber`: if this function was defined in a script returns the current line number
+- `getColumnNumber`: if this function was defined in a script returns the current column number
+- `getEvalOrigin`: if this function was created using a call to eval returns a CallSite object representing the location where eval was called
+- `isToplevel`: is this a toplevel invocation, that is, is this the global object?
+- `isEval`: does this call take place in code defined by a call to eval?
+- `isNative`: is this call in native V8 code?
+- `isConstructor`: is this a constructor call?

+# ansi-styles [![Build Status](https://travis-ci.org/chalk/ansi-styles.svg?branch=master)](https://travis-ci.org/chalk/ansi-styles)
+
+> [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
+
+You probably want the higher-level [chalk](https://github.com/chalk/chalk) module for styling your strings.
+
+![](screenshot.png)
+
+
+## Install
+
+```
+$ npm install ansi-styles
+```
+
+
+## Usage
+
+```js
+const style = require('ansi-styles');
+
+console.log(`${style.green.open}Hello world!${style.green.close}`);
+
+
+// Color conversion between 16/256/truecolor
+// NOTE: If conversion goes to 16 colors or 256 colors, the original color
+//       may be degraded to fit that color palette. This means terminals
+//       that do not support 16 million colors will best-match the
+//       original color.
+console.log(style.bgColor.ansi.hsl(120, 80, 72) + 'Hello world!' + style.bgColor.close);
+console.log(style.color.ansi256.rgb(199, 20, 250) + 'Hello world!' + style.color.close);
+console.log(style.color.ansi16m.hex('#ABCDEF') + 'Hello world!' + style.color.close);
+```
+
+## API
+
+Each style has an `open` and `close` property.
+
+
+## Styles
+
+### Modifiers
+
+- `reset`
+- `bold`
+- `dim`
+- `italic` *(Not widely supported)*
+- `underline`
+- `inverse`
+- `hidden`
+- `strikethrough` *(Not widely supported)*
+
+### Colors
+
+- `black`
+- `red`
+- `green`
+- `yellow`
+- `blue`
+- `magenta`
+- `cyan`
+- `white`
+- `gray` ("bright black")
+- `redBright`
+- `greenBright`
+- `yellowBright`
+- `blueBright`
+- `magentaBright`
+- `cyanBright`
+- `whiteBright`
+
+### Background colors
+
+- `bgBlack`
+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`
+- `bgBlackBright`
+- `bgRedBright`
+- `bgGreenBright`
+- `bgYellowBright`
+- `bgBlueBright`
+- `bgMagentaBright`
+- `bgCyanBright`
+- `bgWhiteBright`
+
+
+## Advanced usage
+
+By default, you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
+
+- `style.modifier`
+- `style.color`
+- `style.bgColor`
+
+###### Example
+
+```js
+console.log(style.color.green.open);
+```
+
+Raw escape codes (i.e. without the CSI escape prefix `\u001B[` and render mode postfix `m`) are available under `style.codes`, which returns a `Map` with the open codes as keys and close codes as values.
+
+###### Example
+
+```js
+console.log(style.codes.get(36));
+//=> 39
+```
+
+
+## [256 / 16 million (TrueColor) support](https://gist.github.com/XVilka/8346728)
+
+`ansi-styles` uses the [`color-convert`](https://github.com/Qix-/color-convert) package to allow for converting between various colors and ANSI escapes, with support for 256 and 16 million colors.
+
+To use these, call the associated conversion function with the intended output, for example:
+
+```js
+style.color.ansi.rgb(100, 200, 15); // RGB to 16 color ansi foreground code
+style.bgColor.ansi.rgb(100, 200, 15); // RGB to 16 color ansi background code
+
+style.color.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
+style.bgColor.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
+
+style.color.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color foreground code
+style.bgColor.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color background code
+```

+# supports-color [![Build Status](https://travis-ci.org/chalk/supports-color.svg?branch=master)](https://travis-ci.org/chalk/supports-color)
+
+> Detect whether a terminal supports color
+
+
+## Install
+
+```
+$ npm install supports-color
+```
+
+
+## Usage
+
+```js
+const supportsColor = require('supports-color');
+
+if (supportsColor) {
+	console.log('Terminal supports color');
+}
+
+if (supportsColor.has256) {
+	console.log('Terminal supports 256 colors');
+}
+
+if (supportsColor.has16m) {
+	console.log('Terminal supports 16 million colors (truecolor)');
+}
+```
+
+
+## API
+
+Returns an `Object`, or `false` if color is not supported.
+
+The returned object specifies a level of support for color through a `.level` property and a corresponding flag:
+
+- `.level = 1` and `.hasBasic = true`: Basic color support (16 colors)
+- `.level = 2` and `.has256 = true`: 256 color support
+- `.level = 3` and `.has16m = true`: Truecolor support (16 million colors)
+
+
+## Info
+
+It obeys the `--color` and `--no-color` CLI flags.
+
+Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, add the environment variable `FORCE_COLOR=1` to forcefully enable color or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
+
+Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.

+
+## Highlights
+
+- Expressive API
+- Highly performant
+- Ability to nest styles
+- [256/Truecolor color support](#256-and-truecolor-color-support)
+- Auto-detects color support
+- Doesn't extend `String.prototype`
+- Clean and focused
+- Actively maintained
+- [Used by ~17,000 packages](https://www.npmjs.com/browse/depended/chalk) as of June 20th, 2017
+
+
+## Install
+
+```console
+$ npm install chalk
+```
+
+
+## Usage
+
+```js
+const chalk = require('chalk');
+
+console.log(chalk.blue('Hello world!'));
+```
+
+Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
+
+```js
+const chalk = require('chalk');
+const log = console.log;
+
+// Combine styled and normal strings
+log(chalk.blue('Hello') + 'World' + chalk.red('!'));
+
+// Compose multiple styles using the chainable API
+log(chalk.blue.bgRed.bold('Hello world!'));
+
+// Pass in multiple arguments
+log(chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz'));
+
+// Nest styles
+log(chalk.red('Hello', chalk.underline.bgBlue('world') + '!'));
+
+// Nest styles of the same type even (color, underline, background)
+log(chalk.green(
+	'I am a green line ' +
+	chalk.blue.underline.bold('with a blue substring') +
+	' that becomes green again!'
+));
+
+// ES2015 template literal
+log(`
+CPU: ${chalk.red('90%')}
+RAM: ${chalk.green('40%')}
+DISK: ${chalk.yellow('70%')}
+`);
+
+// ES2015 tagged template literal
+log(chalk`
+CPU: {red ${cpu.totalPercent}%}
+RAM: {green ${ram.used / ram.total * 100}%}
+DISK: {rgb(255,131,0) ${disk.used / disk.total * 100}%}
+`);
+
+// Use RGB colors in terminal emulators that support it.
+log(chalk.keyword('orange')('Yay for orange colored text!'));
+log(chalk.rgb(123, 45, 67).underline('Underlined reddish color'));
+log(chalk.hex('#DEADED').bold('Bold gray!'));
+```
+
+Easily define your own themes:
+
+```js
+const chalk = require('chalk');
+
+const error = chalk.bold.red;
+const warning = chalk.keyword('orange');
+
+console.log(error('Error!'));
+console.log(warning('Warning!'));
+```
+
+Take advantage of console.log [string substitution](https://nodejs.org/docs/latest/api/console.html#console_console_log_data_args):
+
+```js
+const name = 'Sindre';
+console.log(chalk.green('Hello %s'), name);
+//=> 'Hello Sindre'
+```
+
+
+## API
+
+### chalk.`<style>[.<style>...](string, [string...])`
+
+Example: `chalk.red.bold.underline('Hello', 'world');`
+
+Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that `chalk.red.yellow.green` is equivalent to `chalk.green`.
+
+Multiple arguments will be separated by space.
+
+### chalk.enabled
+
+Color support is automatically detected, as is the level (see `chalk.level`). However, if you'd like to simply enable/disable Chalk, you can do so via the `.enabled` property.
+
+Chalk is enabled by default unless expicitly disabled via the constructor or `chalk.level` is `0`.
+
+If you need to change this in a reusable module, create a new instance:
+
+```js
+const ctx = new chalk.constructor({enabled: false});
+```
+
+### chalk.level
+
+Color support is automatically detected, but you can override it by setting the `level` property. You should however only do this in your own code as it applies globally to all Chalk consumers.
+
+If you need to change this in a reusable module, create a new instance:
+
+```js
+const ctx = new chalk.constructor({level: 0});
+```
+
+Levels are as follows:
+
+0. All colors disabled
+1. Basic color support (16 colors)
+2. 256 color support
+3. Truecolor support (16 million colors)
+
+### chalk.supportsColor
+
+Detect whether the terminal [supports color](https://github.com/chalk/supports-color). Used internally and handled for you, but exposed for convenience.
+
+Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, add the environment variable `FORCE_COLOR=1` to forcefully enable color or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
+
+Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.

+
+## Tagged template literal
+
+Chalk can be used as a [tagged template literal](http://exploringjs.com/es6/ch_template-literals.html#_tagged-template-literals).
+
+```js
+const chalk = require('chalk');
+
+const miles = 18;
+const calculateFeet = miles => miles * 5280;
+
+console.log(chalk`
+  There are {bold 5280 feet} in a mile.
+  In {bold ${miles} miles}, there are {green.bold ${calculateFeet(miles)} feet}.
+`);
+```
+
+Blocks are delimited by an opening curly brace (`{`), a style, some content, and a closing curly brace (`}`).
+
+Template styles are chained exactly like normal Chalk styles. The following two statements are equivalent:
+
+```js
+console.log(chalk.bold.rgb(10, 100, 200)('Hello!'));
+console.log(chalk`{bold.rgb(10,100,200) Hello!}`);
+```
+
+Note that function styles (`rgb()`, `hsl()`, `keyword()`, etc.) may not contain spaces between parameters.
+
+All interpolated values (`` chalk`${foo}` ``) are converted to strings via the `.toString()` method. All curly braces (`{` and `}`) in interpolated value strings are escaped.
+
+
+## 256 and Truecolor color support
+
+Chalk supports 256 colors and [Truecolor](https://gist.github.com/XVilka/8346728) (16 million colors) on supported terminal apps.
+
+Colors are downsampled from 16 million RGB values to an ANSI color format that is supported by the terminal emulator (or by specifying `{level: n}` as a Chalk option). For example, Chalk configured to run at level 1 (basic color support) will downsample an RGB value of #FF0000 (red) to 31 (ANSI escape for red).
+
+Examples:
+
+- `chalk.hex('#DEADED').underline('Hello, world!')`
+- `chalk.keyword('orange')('Some orange text')`
+- `chalk.rgb(15, 100, 204).inverse('Hello!')`
+
+Background versions of these models are prefixed with `bg` and the first level of the module capitalized (e.g. `keyword` for foreground colors and `bgKeyword` for background colors).
+
+- `chalk.bgHex('#DEADED').underline('Hello, world!')`
+- `chalk.bgKeyword('orange')('Some orange text')`
+- `chalk.bgRgb(15, 100, 204).inverse('Hello!')`
+
+The following color models can be used:
+
+- [`rgb`](https://en.wikipedia.org/wiki/RGB_color_model) - Example: `chalk.rgb(255, 136, 0).bold('Orange!')`
+- [`hex`](https://en.wikipedia.org/wiki/Web_colors#Hex_triplet) - Example: `chalk.hex('#FF8800').bold('Orange!')`
+- [`keyword`](https://www.w3.org/wiki/CSS/Properties/color/keywords) (CSS keywords) - Example: `chalk.keyword('orange').bold('Orange!')`
+- [`hsl`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsl(32, 100, 50).bold('Orange!')`
+- [`hsv`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsl(32, 1, 1).bold('Orange!')`
+- [`hwb`](https://en.wikipedia.org/wiki/HWB_color_model)  - Example: `chalk.hsl(32, 0, 50).bold('Orange!')`
+- `ansi16`
+- `ansi256`
+
+
+## Windows
+
+If you're on Windows, do yourself a favor and use [`cmder`](http://cmder.net/) instead of `cmd.exe`.
+
+
+## Origin story
+
+[colors.js](https://github.com/Marak/colors.js) used to be the most popular string styling module, but it has serious deficiencies like extending `String.prototype` which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68) and the package is unmaintained. Although there are other packages, they either do too much or not enough. Chalk is a clean and focused alternative.

+# character-entities-legacy [![Build Status][travis-badge]][travis]
+
+HTML legacy character entity information: for legacy reasons some
+character entities are not required to have a trailing semicolon:
+`&copy` is perfectly okay for `©`.
+
+## Installation
+
+[npm][]:
+
+```bash
+npm install character-entities-legacy
+```
+
+## Usage
+
+```js
+console.log(characterEntitiesLegacy.copy); //=> '©'
+console.log(characterEntitiesLegacy.frac34); //=> '¾'
+console.log(characterEntitiesLegacy.sup1); //=> '¹'
+```
+
+## API
+
+### `characterEntitiesLegacy`
+
+Mapping between (case-sensitive) legacy character entity names to
+replacements.
+
+## Support
+
+See [whatwg/html][html].

+chardet [![Build Status](https://travis-ci.org/runk/node-chardet.png)](https://travis-ci.org/runk/node-chardet)
+=====
+
+Chardet is a character detection module for NodeJS written in pure Javascript.
+Module is based on ICU project http://site.icu-project.org/, which uses character
+occurency analysis to determine the most probable encoding.
+
+## Installation
+
+```
+npm i chardet
+```
+
+## Usage
+
+```javascript
+var chardet = require('chardet');
+chardet.detect(new Buffer('hello there!'));
+// or
+chardet.detectFile('/path/to/file', function(err, encoding) {});
+// or
+chardet.detectFileSync('/path/to/file');
+```
+
+## Working with large data sets
+
+Sometimes, when data set is huge and you want to optimize performace (in tradeoff of less accuracy), 
+you can sample only first N bytes of the buffer:
+
+```javascript
+chardet.detectFile('/path/to/file', { sampleSize: 32 }, function(err, encoding) {});
+```
+
+## Supported Encodings:
+
+* UTF-8
+* UTF-16 LE
+* UTF-16 BE
+* UTF-32 LE
+* UTF-32 BE
+* ISO-2022-JP
+* ISO-2022-KR
+* ISO-2022-CN
+* Shift-JIS
+* Big5
+* EUC-JP
+* EUC-KR
+* GB18030
+* ISO-8859-1
+* ISO-8859-2
+* ISO-8859-5
+* ISO-8859-6
+* ISO-8859-7
+* ISO-8859-8
+* ISO-8859-9
+* windows-1250
+* windows-1251
+* windows-1252
+* windows-1253
+* windows-1254
+* windows-1255
+* windows-1256
+* KOI8-R
+
+Currently only these encodings are supported, more will be added soon.

+CircularJSON
+============
+
+![Downloads](https://img.shields.io/npm/dm/circular-json.svg) [![Build Status](https://travis-ci.org/WebReflection/circular-json.svg?branch=master)](https://travis-ci.org/WebReflection/circular-json) [![Coverage Status](https://coveralls.io/repos/github/WebReflection/circular-json/badge.svg?branch=master)](https://coveralls.io/github/WebReflection/circular-json?branch=master) [![donate](https://img.shields.io/badge/$-donate-ff69b4.svg?maxAge=2592000&style=flat)](https://github.com/WebReflection/donate)
+
+Serializes and deserializes otherwise valid JSON objects containing circular references into and from a specialized JSON format.
+
+- - -
+
+### A Working Solution To A Common Problem
+A usage example:
+
+```JavaScript
+var object = {};
+object.arr = [
+  object, object
+];
+object.arr.push(object.arr);
+object.obj = object;
+
+var serialized = CircularJSON.stringify(object);
+// '{"arr":["~","~","~arr"],"obj":"~"}'
+// NOTE: CircularJSON DOES NOT parse JS
+// it handles receiver and reviver callbacks
+
+var unserialized = CircularJSON.parse(serialized);
+// { arr: [ [Circular], [Circular] ],
+// obj: [Circular] }
+
+unserialized.obj === unserialized;
+unserialized.arr[0] === unserialized;
+unserialized.arr.pop() === unserialized.arr;
+```
+
+A quick summary:
+
+  * uses `~` as a special prefix symbol to denote which parent the reference belongs to (i.e. `~root~child1~child2`)
+  * reasonably fast in both serialization and deserialization
+  * compact serialization for easier and slimmer transportation across environments
+  * [tested and covered](test/circular-json.js) over nasty structures too
+  * compatible with all JavaScript engines
+  
+Node Installation & Usage
+============
+
+```bash
+npm install --save circular-json
+```
+
+```javascript
+'use strict';
+
+var
+  CircularJSON = require('circular-json'),
+  obj = { foo: 'bar' },
+  str
+;
+  
+obj.self = obj;
+str = CircularJSON.stringify(obj);
+```
+
+There are no dependencies.
+
+Browser Installation & Usage
+================
+
+* Global: <build/circular-json.js>
+* AMD: <build/circular-json.amd.js>
+* CommonJS: <build/circular-json.node.js>
+
+(generated via [gitstrap](https://github.com/WebReflection/gitstrap))
+
+```html
+<script src="build/circular-json.js"></script>
+```
+
+```javascript
+'use strict';
+
+var CircularJSON = window.CircularJSON
+  , obj = { foo: 'bar' }
+  , str
+  ;
+  
+obj.self = obj;
+str = CircularJSON.stringify(obj);
+```
+
+NOTE: Platforms without native JSON (i.e. MSIE <= 8) requires `json3.js` or similar.
+
+It is also *a bad idea* to `CircularJSON.parse(JSON.stringify(object))` because of those manipulation used in `CircularJSON.stringify()` able to make parsing safe and secure.
+
+As summary: `CircularJSON.parse(CircularJSON.stringify(object))` is the way to go, same is for `JSON.parse(JSON.stringify(object))`.
+
+API
+===
+
+It's the same as native JSON, except the fourth parameter `placeholder`, which circular references to be replaced with `"[Circular]"` (i.e. for logging).
+
+* CircularJSON.stringify(object, replacer, spacer, placeholder)
+* CircularJSON.parse(string, reviver)
+
+Bear in mind `JSON.parse(CircularJSON.stringify(object))` will work but not produce the expected output.
+
+Similar Libraries
+=======
+
+### Why Not the [@izs](https://twitter.com/izs) One
+The module [json-stringify-safe](https://github.com/isaacs/json-stringify-safe) seems to be for `console.log()`  but it's completely pointless for `JSON.parse()`, being latter one unable to retrieve back the initial structure. Here an example:
+
+```JavaScript
+// a logged object with circular references
+{
+  "circularRef": "[Circular]",
+  "list": [
+    "[Circular]",
+    "[Circular]"
+  ]
+}
+// what do we do with above output ?
+```
+
+Just type this in your `node` console: `var o = {}; o.a = o; console.log(o);`. The output will be `{ a: [Circular] }` ... good, but that ain't really solving the problem.
+
+However, if that's all you need, the function used to create that kind of output is probably faster than `CircularJSON` and surely fits in less lines of code.
+
+
+### Why Not {{put random name}} Solution
+So here the thing: circular references can be wrong but, if there is a need for them, any attempt to ignore them or remove them can be considered just a failure.
+
+Not because the method is bad or it's not working, simply because the circular info, the one we needed and used in the first place, is lost!
+
+In this case, `CircularJSON` does even more than just solve circular and recursions: it maps all same objects so that less memory is used as well on deserialization as less bandwidth too!
+It's able to redefine those references back later on so the way we store is the way we retrieve and in a reasonably performant way, also trusting the snappy and native `JSON` methods to iterate.

+cli-width
+=========
+
+Get stdout window width, with four fallbacks, `tty`, `output.columns`, a custom environment variable and then a default.
+
+[![npm version](https://badge.fury.io/js/cli-width.svg)](http://badge.fury.io/js/cli-width)
+[![Build Status](https://travis-ci.org/knownasilya/cli-width.svg)](https://travis-ci.org/knownasilya/cli-width)
+[![Coverage Status](https://coveralls.io/repos/knownasilya/cli-width/badge.svg?branch=master&service=github)](https://coveralls.io/github/knownasilya/cli-width?branch=master)
+
+## Usage
+
+```
+npm install --save cli-width
+```
+
+```js
+'use strict';
+
+var cliWidth = require('cli-width');
+
+cliWidth(); // maybe 204 :)
+```
+
+You can also set the `CLI_WIDTH` environment variable.
+
+If none of the methods are supported, and the environment variable isn't set,
+the default width value is going to be `0`, that can be changed using the configurable `options`.
+
+## API
+
+### cliWidth([options])
+
+`cliWidth` can be configured using an `options` parameter, the possible properties are:
+
+- **defaultWidth**\<number\> Defines a default value to be used if none of the methods are available, defaults to `0`
+- **output**\<object\> A stream to be used to read width values from, defaults to `process.stdout`
+- **tty**\<object\> TTY module to try to read width from as a fallback, defaults to `require('tty')`
+
+
+### Examples
+
+Defining both a default width value and a stream output to try to read from:
+
+```js
+var cliWidth = require('cli-width');
+var ttys = require('ttys');
+
+cliWidth({
+  defaultWidth: 80,
+  output: ttys.output
+});
+```
+
+Defines a different tty module to read width from:
+
+```js
+var cliWidth = require('cli-width');
+var ttys = require('ttys');
+
+cliWidth({
+  tty: ttys
+});
+```
+
+## Tests
+
+```bash
+npm install
+npm test
+```
+
+Coverage can be generated with `npm run coverage`.

+
+  Generator based control flow goodness for nodejs and the browser,
+  using promises, letting you write non-blocking code in a nice-ish way.
+
+## Co v4
+
+  `co@4.0.0` has been released, which now relies on promises.
+  It is a stepping stone towards [ES7 async/await](https://github.com/lukehoban/ecmascript-asyncawait).
+  The primary API change is how `co()` is invoked.
+  Before, `co` returned a "thunk", which you then called with a callback and optional arguments.
+  Now, `co()` returns a promise.
+
+```js
+co(function* () {
+  var result = yield Promise.resolve(true);
+  return result;
+}).then(function (value) {
+  console.log(value);
+}, function (err) {
+  console.error(err.stack);
+});
+```
+
+  If you want to convert a `co`-generator-function into a regular function that returns a promise,
+  you now use `co.wrap(fn*)`.
+
+```js
+var fn = co.wrap(function* (val) {
+  return yield Promise.resolve(val);
+});
+
+fn(true).then(function (val) {
+
+});
+```
+
+## Platform Compatibility
+
+  `co@4+` requires a `Promise` implementation.
+  For versions of node `< 0.11` and for many older browsers,
+  you should/must include your own `Promise` polyfill.
+
+  When using node 0.11.x or greater, you must use the `--harmony-generators`
+  flag or just `--harmony` to get access to generators.
+
+  When using node 0.10.x and lower or browsers without generator support,
+  you must use [gnode](https://github.com/TooTallNate/gnode) and/or [regenerator](http://facebook.github.io/regenerator/).
+
+  io.js is supported out of the box, you can use `co` without flags or polyfills.
+
+## Installation
+
+```
+$ npm install co
+```
+
+## Associated libraries
+
+Any library that returns promises work well with `co`.
+
+- [mz](https://github.com/normalize/mz) - wrap all of node's code libraries as promises.
+
+View the [wiki](https://github.com/visionmedia/co/wiki) for more libraries.
+
+## Examples
+
+```js
+var co = require('co');
+
+co(function *(){
+  // yield any promise
+  var result = yield Promise.resolve(true);
+}).catch(onerror);
+
+co(function *(){
+  // resolve multiple promises in parallel
+  var a = Promise.resolve(1);
+  var b = Promise.resolve(2);
+  var c = Promise.resolve(3);
+  var res = yield [a, b, c];
+  console.log(res);
+  // => [1, 2, 3]
+}).catch(onerror);
+
+// errors can be try/catched
+co(function *(){
+  try {
+    yield Promise.reject(new Error('boom'));
+  } catch (err) {
+    console.error(err.message); // "boom"
+ }
+}).catch(onerror);
+
+function onerror(err) {
+  // log any uncaught errors
+  // co will not throw any errors you do not handle!!!
+  // HANDLE ALL YOUR ERRORS!!!
+  console.error(err.stack);
+}
+```
+
+## Yieldables
+
+  The `yieldable` objects currently supported are:
+
+  - promises
+  - thunks (functions)
+  - array (parallel execution)
+  - objects (parallel execution)
+  - generators (delegation)
+  - generator functions (delegation)
+
+Nested `yieldable` objects are supported, meaning you can nest
+promises within objects within arrays, and so on!
+
+### Promises
+
+[Read more on promises!](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise)
+
+### Thunks
+
+Thunks are functions that only have a single argument, a callback.
+Thunk support only remains for backwards compatibility and may
+be removed in future versions of `co`.
+
+### Arrays
+
+`yield`ing an array will resolve all the `yieldables` in parallel.
+
+```js
+co(function* () {
+  var res = yield [
+    Promise.resolve(1),
+    Promise.resolve(2),
+    Promise.resolve(3),
+  ];
+  console.log(res); // => [1, 2, 3]
+}).catch(onerror);
+```
+
+### Objects
+
+Just like arrays, objects resolve all `yieldable`s in parallel.
+
+```js
+co(function* () {
+  var res = yield {
+    1: Promise.resolve(1),
+    2: Promise.resolve(2),
+  };
+  console.log(res); // => { 1: 1, 2: 2 }
+}).catch(onerror);
+```
+
+### Generators and Generator Functions
+
+Any generator or generator function you can pass into `co`
+can be yielded as well. This should generally be avoided
+as we should be moving towards spec-compliant `Promise`s instead.
+
+## API
+
+### co(fn*).then( val => )
+
+Returns a promise that resolves a generator, generator function,
+or any function that returns a generator.
+
+```js
+co(function* () {
+  return yield Promise.resolve(true);
+}).then(function (val) {
+  console.log(val);
+}, function (err) {
+  console.error(err.stack);
+});
+```
+
+### var fn = co.wrap(fn*)
+
+Convert a generator into a regular function that returns a `Promise`.
+
+```js
+var fn = co.wrap(function* (val) {
+  return yield Promise.resolve(val);
+});
+
+fn(true).then(function (val) {
+
+});
+```

+# color-convert
+
+[![Build Status](https://travis-ci.org/Qix-/color-convert.svg?branch=master)](https://travis-ci.org/Qix-/color-convert)
+
+Color-convert is a color conversion library for JavaScript and node.
+It converts all ways between `rgb`, `hsl`, `hsv`, `hwb`, `cmyk`, `ansi`, `ansi16`, `hex` strings, and CSS `keyword`s (will round to closest):
+
+```js
+var convert = require('color-convert');
+
+convert.rgb.hsl(140, 200, 100);             // [96, 48, 59]
+convert.keyword.rgb('blue');                // [0, 0, 255]
+
+var rgbChannels = convert.rgb.channels;     // 3
+var cmykChannels = convert.cmyk.channels;   // 4
+var ansiChannels = convert.ansi16.channels; // 1
+```
+
+# Install
+
+```console
+$ npm install color-convert
+```
+
+# API
+
+Simply get the property of the _from_ and _to_ conversion that you're looking for.
+
+All functions have a rounded and unrounded variant. By default, return values are rounded. To get the unrounded (raw) results, simply tack on `.raw` to the function.
+
+All 'from' functions have a hidden property called `.channels` that indicates the number of channels the function expects (not including alpha).
+
+```js
+var convert = require('color-convert');
+
+// Hex to LAB
+convert.hex.lab('DEADBF');         // [ 76, 21, -2 ]
+convert.hex.lab.raw('DEADBF');     // [ 75.56213190997677, 20.653827952644754, -2.290532499330533 ]
+
+// RGB to CMYK
+convert.rgb.cmyk(167, 255, 4);     // [ 35, 0, 98, 0 ]
+convert.rgb.cmyk.raw(167, 255, 4); // [ 34.509803921568626, 0, 98.43137254901961, 0 ]
+```
+
+### Arrays
+All functions that accept multiple arguments also support passing an array.
+
+Note that this does **not** apply to functions that convert from a color that only requires one value (e.g. `keyword`, `ansi256`, `hex`, etc.)
+
+```js
+var convert = require('color-convert');
+
+convert.rgb.hex(123, 45, 67);      // '7B2D43'
+convert.rgb.hex([123, 45, 67]);    // '7B2D43'
+```
+
+## Routing
+
+Conversions that don't have an _explicitly_ defined conversion (in [conversions.js](conversions.js)), but can be converted by means of sub-conversions (e.g. XYZ -> **RGB** -> CMYK), are automatically routed together. This allows just about any color model supported by `color-convert` to be converted to any other model, so long as a sub-conversion path exists. This is also true for conversions requiring more than one step in between (e.g. LCH -> **LAB** -> **XYZ** -> **RGB** -> Hex).
+
+Keep in mind that extensive conversions _may_ result in a loss of precision, and exist only to be complete. For a list of "direct" (single-step) conversions, see [conversions.js](conversions.js).
+
+# Contribute
+
+If there is a new model you would like to support, or want to add a direct conversion between two existing models, please send us a pull request.

+=======
+
+``` js
+var concatMap = require('concat-map');
+var xs = [ 1, 2, 3, 4, 5, 6 ];
+var ys = concatMap(xs, function (x) {
+    return x % 2 ? [ x - 0.1, x, x + 0.1 ] : [];

+***
+
+```
+[ 0.9, 1, 1.1, 2.9, 3, 3.1, 4.9, 5, 5.1 ]
+```
+
+methods
+=======
+
+``` js
+var concatMap = require('concat-map')
+```
+
+concatMap(xs, fn)
+-----------------
+
+Return an array of concatenated elements by calling `fn(x, i)` for each element
+`x` and each index `i` in the array `xs`.
+
+When `fn(x, i)` returns an array, its result will be concatenated with the
+result array. If `fn(x, i)` returns anything else, that value will be pushed
+onto the end of the result array.
+
+install
+=======
+
+With [npm](http://npmjs.org) do:
+
+```
+npm install concat-map

+# concat-stream
+
+Writable stream that concatenates all the data from a stream and calls a callback with the result. Use this when you want to collect all the data from a stream into a single buffer.
+
+[![Build Status](https://travis-ci.org/maxogden/concat-stream.svg?branch=master)](https://travis-ci.org/maxogden/concat-stream)
+
+[![NPM](https://nodei.co/npm/concat-stream.png)](https://nodei.co/npm/concat-stream/)
+
+### description
+
+Streams emit many buffers. If you want to collect all of the buffers, and when the stream ends concatenate all of the buffers together and receive a single buffer then this is the module for you.
+
+Only use this if you know you can fit all of the output of your stream into a single Buffer (e.g. in RAM).
+
+There are also `objectMode` streams that emit things other than Buffers, and you can concatenate these too. See below for details.
+
+## Related
+
+`concat-stream` is part of the [mississippi stream utility collection](https://github.com/maxogden/mississippi) which includes more useful stream modules similar to this one.
+
+### examples
+
+#### Buffers
+
+```js
+var fs = require('fs')
+var concat = require('concat-stream')
+
+var readStream = fs.createReadStream('cat.png')
+var concatStream = concat(gotPicture)
+
+readStream.on('error', handleError)
+readStream.pipe(concatStream)
+
+function gotPicture(imageBuffer) {
+  // imageBuffer is all of `cat.png` as a node.js Buffer
+}
+
+function handleError(err) {
+  // handle your error appropriately here, e.g.:
+  console.error(err) // print the error to STDERR
+  process.exit(1) // exit program with non-zero exit code
+}
+
+```
+
+#### Arrays
+
+```js
+var write = concat(function(data) {})
+write.write([1,2,3])
+write.write([4,5,6])
+write.end()
+// data will be [1,2,3,4,5,6] in the above callback
+```
+
+#### Uint8Arrays
+
+```js
+var write = concat(function(data) {})
+var a = new Uint8Array(3)
+a[0] = 97; a[1] = 98; a[2] = 99
+write.write(a)
+write.write('!')
+write.end(Buffer('!!1'))
+```
+
+See `test/` for more examples
+
+# methods
+
+```js
+var concat = require('concat-stream')
+```
+
+## var writable = concat(opts={}, cb)
+
+Return a `writable` stream that will fire `cb(data)` with all of the data that
+was written to the stream. Data can be written to `writable` as strings,
+Buffers, arrays of byte integers, and Uint8Arrays. 
+
+By default `concat-stream` will give you back the same data type as the type of the first buffer written to the stream. Use `opts.encoding` to set what format `data` should be returned as, e.g. if you if you don't want to rely on the built-in type checking or for some other reason.
+
+* `string` - get a string
+* `buffer` - get back a Buffer
+* `array` - get an array of byte integers
+* `uint8array`, `u8`, `uint8` - get back a Uint8Array
+* `object`, get back an array of Objects
+
+If you don't specify an encoding, and the types can't be inferred (e.g. you write things that aren't in the list above), it will try to convert concat them into a `Buffer`.
+
+If nothing is written to `writable` then `data` will be an empty array `[]`.
+
+# error handling
+
+`concat-stream` does not handle errors for you, so you must handle errors on whatever streams you pipe into `concat-stream`. This is a general rule when programming with node.js streams: always handle errors on each and every stream. Since `concat-stream` is not itself a stream it does not emit errors.
+
+We recommend using [`end-of-stream`](https://npmjs.org/end-of-stream) or [`pump`](https://npmjs.org/pump) for writing error tolerant stream code.

+
+A cross platform solution to node's spawn and spawnSync.
+
+
+## Installation
+
+`$ npm install cross-spawn`
+
+If you are using `spawnSync` on node 0.10 or older, you will also need to install `spawn-sync`:
+
+`$ npm install spawn-sync`
+
+
+## Why
+
+Node has issues when using spawn on Windows:
+
+- It ignores [PATHEXT](https://github.com/joyent/node/issues/2318)
+- It does not support [shebangs](http://pt.wikipedia.org/wiki/Shebang)
+- No `options.shell` support on node < v6
+- It does not allow you to run `del` or `dir`
+
+All these issues are handled correctly by `cross-spawn`.
+There are some known modules, such as [win-spawn](https://github.com/ForbesLindesay/win-spawn), that try to solve this but they are either broken or provide faulty escaping of shell arguments.
+
+
+## Usage
+
+Exactly the same way as node's [`spawn`](https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options) or [`spawnSync`](https://nodejs.org/api/child_process.html#child_process_child_process_spawnsync_command_args_options), so it's a drop in replacement.
+
+
+```js
+var spawn = require('cross-spawn');
+
+// Spawn NPM asynchronously
+var child = spawn('npm', ['list', '-g', '-depth', '0'], { stdio: 'inherit' });
+
+// Spawn NPM synchronously
+var results = spawn.sync('npm', ['list', '-g', '-depth', '0'], { stdio: 'inherit' });
+```
+
+
+## Caveats
+
+#### `options.shell` as an alternative to `cross-spawn`
+
+Starting from node v6, `spawn` has a `shell` option that allows you run commands from within a shell. This new option solves most of the problems that `cross-spawn` attempts to solve, but:
+
+- It's not supported in node < v6
+- It has no support for shebangs on Windows
+- You must manually escape the command and arguments which is very error prone, specially when passing user input
+
+If you are using the `shell` option to spawn a command in a cross platform way, consider using `cross-spawn` instead. You have been warned.
+
+
+#### Shebangs
+
+While `cross-spawn` handles shebangs on Windows, its support is limited: e.g.: it doesn't handle arguments after the path, e.g.: `#!/bin/bash -e`.
+
+Remember to always test your code on Windows!

+
+A tiny JavaScript debugging utility modelled after Node.js core's debugging
+technique. Works in Node.js and web browsers.
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
+
+Example [_app.js_](./examples/node/app.js):
+
+```js
+var debug = require('debug')('http')
+  , http = require('http')
+  , name = 'My App';
+
+// fake app
+
+debug('booting %o', name);
+
+http.createServer(function(req, res){
+  debug(req.method + ' ' + req.url);
+  res.end('hello\n');
+}).listen(3000, function(){
+  debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example [_worker.js_](./examples/node/worker.js):
+
+```js
+var a = require('debug')('worker:a')
+  , b = require('debug')('worker:b');
+
+function work() {
+  a('doing lots of uninteresting work');
+  setTimeout(work, Math.random() * 1000);
+}
+
+work();
+
+function workb() {
+  b('doing some work');
+  setTimeout(workb, Math.random() * 2000);
+}
+
+workb();
+```
+
+The `DEBUG` environment variable is then used to enable these based on space or
+comma-delimited names.
+
+Here are some examples:
+
+<img width="647" alt="screen shot 2017-08-08 at 12 53 04 pm" src="https://user-images.githubusercontent.com/71256/29091703-a6302cdc-7c38-11e7-8304-7c0b3bc600cd.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 38 pm" src="https://user-images.githubusercontent.com/71256/29091700-a62a6888-7c38-11e7-800b-db911291ca2b.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 25 pm" src="https://user-images.githubusercontent.com/71256/29091701-a62ea114-7c38-11e7-826a-2692bedca740.png">
+
+#### Windows note
+
+On Windows the environment variable is set using the `set` command.
+
+```cmd
+set DEBUG=*,-not_this
+```
+
+Note that PowerShell uses different syntax to set environment variables.
+
+```cmd
+$env:DEBUG = "*,-not_this"
+```
+
+Then, run the program to be debugged as usual.
+
+
+## Namespace Colors
+
+Every debug instance has a color generated for it based on its namespace name.
+This helps when visually parsing the debug output to identify which debug instance
+a debug line belongs to.
+
+#### Node.js
+
+In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
+the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
+otherwise debug will only use a small handful of basic colors.
+
+<img width="521" src="https://user-images.githubusercontent.com/71256/29092181-47f6a9e6-7c3a-11e7-9a14-1928d8a711cd.png">
+
+#### Web Browser
+
+Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+option. These are WebKit web inspectors, Firefox ([since version
+31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+and the Firebug plugin for Firefox (any version).
+
+<img width="524" src="https://user-images.githubusercontent.com/71256/29092033-b65f9f2e-7c39-11e7-8e32-f6f0d8e865c1.png">
+
+
+## Millisecond diff
+
+When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
+
+When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091956-6bd78372-7c39-11e7-8c55-c948396d6edd.png">
+
+
+## Conventions
+
+If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser".  If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable.  You can then use it for normal output as well as debug output.
+
+## Wildcards
+
+The `*` character may be used as a wildcard. Suppose for example your library has
+debuggers named "connect:bodyParser", "connect:compress", "connect:session",
+instead of listing all three with
+`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do
+`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+You can also exclude specific debuggers by prefixing them with a "-" character.
+For example, `DEBUG=*,-connect:*` would include all debuggers except those
+starting with "connect:".
+
+## Environment Variables
+
+When running through Node.js, you can set a few environment variables that will
+change the behavior of the debug logging:
+
+| Name      | Purpose                                         |
+|-----------|-------------------------------------------------|
+| `DEBUG`   | Enables/disables specific debugging namespaces. |
+| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY).  |
+| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
+| `DEBUG_DEPTH` | Object inspection depth.                    |
+| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
+
+
+__Note:__ The environment variables beginning with `DEBUG_` end up being
+converted into an Options object that gets used with `%o`/`%O` formatters.
+See the Node.js documentation for
+[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
+for the complete list.
+
+## Formatters
+
+Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting.
+Below are the officially supported formatters:
+
+| Formatter | Representation |
+|-----------|----------------|
+| `%O`      | Pretty-print an Object on multiple lines. |
+| `%o`      | Pretty-print an Object all on a single line. |
+| `%s`      | String. |
+| `%d`      | Number (both integer and float). |
+| `%j`      | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
+| `%%`      | Single percent sign ('%'). This does not consume an argument. |
+
+
+### Custom formatters
+
+You can add custom formatters by extending the `debug.formatters` object.
+For example, if you wanted to add support for rendering a Buffer as hex with
+`%h`, you could do something like:
+
+```js
+const createDebug = require('debug')
+createDebug.formatters.h = (v) => {
+  return v.toString('hex')
+}
+
+// …elsewhere
+const debug = createDebug('foo')
+debug('this is hex: %h', new Buffer('hello world'))
+//   foo this is hex: 68656c6c6f20776f726c6421 +0ms
+```
+
+
+## Browser Support
+
+You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
+or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
+if you don't want to build it yourself.
+
+Debug's enable state is currently persisted by `localStorage`.
+Consider the situation shown below where you have `worker:a` and `worker:b`,
+and wish to debug both. You can enable this using `localStorage.debug`:
+
+```js
+localStorage.debug = 'worker:*'
+```
+
+And then refresh the page.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+  a('doing some work');
+}, 1000);
+
+setInterval(function(){
+  b('doing some work');
+}, 1200);
+```
+
+
+## Output streams
+
+  By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
+
+Example [_stdout.js_](./examples/node/stdout.js):
+
+```js
+var debug = require('debug');
+var error = debug('app:error');
+
+// by default stderr is used
+error('goes to stderr!');
+
+var log = debug('app:log');
+// set this namespace to log via console.log
+log.log = console.log.bind(console); // don't forget to bind to console!
+log('goes to stdout');
+error('still goes to stderr!');
+
+// set all output to go via console.info
+// overrides all per-namespace log settings
+debug.log = console.info.bind(console);
+error('now goes to stdout via console.info');
+log('still goes to stdout, but via console.info now');
+```
+
+## Checking whether a debug target is enabled
+
+After you've created a debug instance, you can determine whether or not it is
+enabled by checking the `enabled` property:
+
+```javascript
+const debug = require('debug')('http');
+
+if (debug.enabled) {
+  // do stuff...
+}
+```
+
+You can also manually toggle this property to force the debug instance to be
+enabled or disabled.

+deep-is
+==========
+
+Node's `assert.deepEqual() algorithm` as a standalone module. Exactly like
+[deep-equal](https://github.com/substack/node-deep-equal) except for the fact that `deepEqual(NaN, NaN) === true`.
+
+This module is around [5 times faster](https://gist.github.com/2790507)
+than wrapping `assert.deepEqual()` in a `try/catch`.
+
+[![browser support](http://ci.testling.com/thlorenz/deep-is.png)](http://ci.testling.com/thlorenz/deep-is)
+
+[![build status](https://secure.travis-ci.org/thlorenz/deep-is.png)](http://travis-ci.org/thlorenz/deep-is)
+
+example
+=======
+
+``` js
+var equal = require('deep-is');
+console.dir([
+    equal(
+        { a : [ 2, 3 ], b : [ 4 ] },
+        { a : [ 2, 3 ], b : [ 4 ] }

+    equal(
+        { x : 5, y : [6] },
+        { x : 5, y : 6 }
+    )
+]);
+```
+
+methods
+=======
+
+var deepIs = require('deep-is')
+
+deepIs(a, b)
+---------------
+
+Compare objects `a` and `b`, returning whether they are equal according to a

+# del [![Build Status](https://travis-ci.org/sindresorhus/del.svg?branch=master)](https://travis-ci.org/sindresorhus/del)
+
+> Delete files and folders using [globs](https://github.com/isaacs/minimatch#usage)
+
+Pretty much [rimraf](https://github.com/isaacs/rimraf) with a Promise API and support for multiple files and globbing. It also protects you against deleting the current working directory and above.
+
+---
+
+<p align="center"><b>🔥 Want to strengthen your core JavaScript skills and master ES6?</b><br>I would personally recommend this awesome <a href="https://ES6.io/friend/AWESOME">ES6 course</a> by Wes Bos.</p>
+
+---
+
+
+## Install
+
+```
+$ npm install --save del
+```
+
+
+## Usage
+
+```js
+const del = require('del');
+
+del(['tmp/*.js', '!tmp/unicorn.js']).then(paths => {
+	console.log('Deleted files and folders:\n', paths.join('\n'));
+});
+```
+
+
+## Beware
+
+The glob pattern `**` matches all children and *the parent*.
+
+So this won't work:
+
+```js
+del.sync(['public/assets/**', '!public/assets/goat.png']);
+```
+
+You have to explicitly ignore the parent directories too:
+
+```js
+del.sync(['public/assets/**', '!public/assets', '!public/assets/goat.png']);
+```
+
+Suggestions on how to improve this welcome!
+
+
+## API
+
+### del(patterns, [options])
+
+Returns a promise for an array of deleted paths.
+
+### del.sync(patterns, [options])
+
+Returns an array of deleted paths.
+
+#### patterns
+
+Type: `string`, `array`
+
+See supported minimatch [patterns](https://github.com/isaacs/minimatch#usage).
+
+- [Pattern examples with expected matches](https://github.com/sindresorhus/multimatch/blob/master/test.js)
+- [Quick globbing pattern overview](https://github.com/sindresorhus/multimatch#globbing-patterns)
+
+#### options
+
+Type: `object`
+
+See the `node-glob` [options](https://github.com/isaacs/node-glob#options).
+
+##### force
+
+Type: `boolean`  
+Default: `false`
+
+Allow deleting the current working directory and outside.
+
+##### dryRun
+
+Type: `boolean`  
+Default: `false`
+
+See what would be deleted.
+
+```js
+const del = require('del');
+
+del(['tmp/*.js'], {dryRun: true}).then(paths => {
+	console.log('Files and folders that would be deleted:\n', paths.join('\n'));
+});
+```
+
+
+## CLI
+
+See [del-cli](https://github.com/sindresorhus/del-cli) for a CLI for this module and [trash-cli](https://github.com/sindresorhus/trash-cli) for a safe version that is suitable for running by hand.

+# Doctrine
+
+Doctrine is a [JSDoc](http://usejsdoc.org) parser that parses documentation comments from JavaScript (you need to pass in the comment, not a whole JavaScript file).
+
+## Installation
+
+You can install Doctrine using [npm](https://npmjs.com):
+
+```
+$ npm install doctrine --save-dev
+```
+
+Doctrine can also be used in web browsers using [Browserify](http://browserify.org).
+
+## Usage
+
+Require doctrine inside of your JavaScript:
+
+```js
+var doctrine = require("doctrine");
+```
+
+### parse()
+
+The primary method is `parse()`, which accepts two arguments: the JSDoc comment to parse and an optional options object. The available options are:
+
+* `unwrap` - set to `true` to delete the leading `/**`, any `*` that begins a line, and the trailing `*/` from the source text. Default: `false`.
+* `tags` - an array of tags to return. When specified, Doctrine returns only tags in this array. For example, if `tags` is `["param"]`, then only `@param` tags will be returned. Default: `null`.
+* `recoverable` - set to `true` to keep parsing even when syntax errors occur. Default: `false`.
+* `sloppy` - set to `true` to allow optional parameters to be specified in brackets (`@param {string} [foo]`). Default: `false`.
+* `lineNumbers` - set to `true` to add `lineNumber` to each node, specifying the line on which the node is found in the source. Default: `false`.
+
+Here's a simple example:
+
+```js
+var ast = doctrine.parse(
+    [
+        "/**",
+        " * This function comment is parsed by doctrine",
+        " * @param {{ok:String}} userName",
+        "*/"
+    ].join('\n'), { unwrap: true });
+```
+
+This example returns the following AST:
+
+    {
+        "description": "This function comment is parsed by doctrine",
+        "tags": [
+            {
+                "title": "param",
+                "description": null,
+                "type": {
+                    "type": "RecordType",
+                    "fields": [
+                        {
+                            "type": "FieldType",
+                            "key": "ok",
+                            "value": {
+                                "type": "NameExpression",
+                                "name": "String"
+                            }
+                        }
+                    ]
+                },
+                "name": "userName"
+            }
+        ]
+    }

+## Frequently Asked Questions
+
+### Can I pass a whole JavaScript file to Doctrine?
+
+No. Doctrine can only parse JSDoc comments, so you'll need to pass just the JSDoc comment to Doctrine in order to work.

+# eslint-plugin-markdown
+
+![Screenshot](screenshot.png)
+
+An [ESLint](http://eslint.org/) plugin to lint JavaScript in Markdown.
+
+Supported extensions are `.markdown`, `.mdown`, `.mkdn`, and `.md`.
+
+## Usage
+
+Install the plugin:
+
+```sh
+npm install --save-dev eslint eslint-plugin-markdown
+```
+
+Add it to your `.eslintrc`:
+
+```json
+{
+    "plugins": [
+        "markdown"
+    ]
+}
+```
+
+Run ESLint on `.md` files:
+
+```sh
+eslint --ext md .
+```
+
+It will lint `js`, `javascript`, `jsx`, or `node` [fenced code blocks](https://help.github.com/articles/github-flavored-markdown/#fenced-code-blocks) in your Markdown documents:
+
+    ```js
+    // This gets linted
+    var answer = 6 * 7;
+    console.log(answer);
+    ```
+
+    ```JavaScript
+    // This also gets linted
+
+    /* eslint quotes: [2, "double"] */
+
+    function hello() {
+        console.log("Hello, world!");
+    }
+    hello();
+    ```
+
+    ```jsx
+    // This gets linted too
+    var div = <div className="jsx"></div>;
+    ```
+
+    ```node
+    // And this
+    console.log(process.version);
+    ```
+
+Blocks that don't specify either `js`, `javascript`, `jsx`, or `node` syntax are ignored:
+
+    ```
+    This is plain text and doesn't get linted.
+    ```
+
+    ```python
+    print("This doesn't get linted either.")
+    ```
+
+## Configuration Comments
+
+The processor will convert HTML comments immediately preceding a code block into JavaScript block comments and insert them at the beginning of the source code that it passes to ESLint. This permits configuring ESLint via configuration comments while keeping the configuration comments themselves hidden when the markdown is rendered. Comment bodies are passed through unmodified, so the plugin supports any [configuration comments](http://eslint.org/docs/user-guide/configuring) supported by ESLint itself.
+
+This example enables the `browser` environment, disables the `no-alert` rule, and configures the `quotes` rule to prefer single quotes:
+
+    <!-- eslint-env browser -->
+    <!-- eslint-disable no-alert -->
+    <!-- eslint quotes: ["error", "single"] -->
+
+    ```js
+    alert('Hello, world!');
+    ```
+
+Each code block in a file is linted separately, so configuration comments apply only to the code block that immediately follows.
+
+    Assuming `no-alert` is enabled in `.eslintrc`, the first code block will have no error from `no-alert`:
+
+    <!-- eslint-env browser -->
+    <!-- eslint-disable no-alert -->
+
+    ```js
+    alert("Hello, world!");
+    ```
+
+    But the next code block will have an error from `no-alert`:
+
+    <!-- eslint-env browser -->
+
+    ```js
+    alert("Hello, world!");
+    ```
+
+## Skipping Blocks
+
+Sometimes it can be useful to have code blocks marked with `js` even though they don't contain valid JavaScript syntax, such as commented JSON blobs that need `js` syntax highlighting. Standard `eslint-disable` comments only silence rule reporting, but ESLint still reports any syntax errors it finds. In cases where a code block should not even be parsed, insert a non-standard `<!-- eslint-skip -->` comment before the block, and this plugin will hide the following block from ESLint. Neither rule nor syntax errors will be reported.
+
+    There are comments in this JSON, so we use `js` syntax for better
+    highlighting. Skip the block to prevent warnings about invalid syntax.
+
+    <!-- eslint-skip -->
+
+    ```js
+    {
+        // This code block is hidden from ESLint.
+        "hello": "world"
+    }
+    ```
+
+    ```js
+    console.log("This code block is linted normally.");
+    ```
+
+## Unsatisfiable Rules
+
+Since code blocks are not files themselves but embedded inside a Markdown document, some rules do not apply to Markdown code blocks, and messages from these rules are automatically suppressed:
+
+- `eol-last`

+# ESLint Scope
+
+ESLint Scope is the [ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm) scope analyzer used in ESLint. It is a fork of [escope](http://github.com/estools/escope).
+
+## Usage
+
+Install:
+
+```
+npm i eslint-scope --save
+```
+
+Example:
+
+```js
+var eslintScope = require('eslint-scope');
+var espree = require('espree');
+var estraverse = require('estraverse');
+
+var ast = espree.parse(code);
+var scopeManager = eslintScope.analyze(ast);
+
+var currentScope = scopeManager.acquire(ast);   // global scope
+
+estraverse.traverse(ast, {
+    enter: function(node, parent) {
+        // do stuff
+
+        if (/Function/.test(node.type)) {
+            currentScope = scopeManager.acquire(node);  // get current function scope
+        }
+    },
+    leave: function(node, parent) {
+        if (/Function/.test(node.type)) {
+            currentScope = currentScope.upper;  // set to parent scope
+        }
+
+        // do stuff
+    }
+});
+```

+# Espree
+
+Espree started out as a fork of [Esprima](http://esprima.org) v1.2.2, the last stable published released of Esprima before work on ECMAScript 6 began. Espree is now built on top of [Acorn](https://github.com/ternjs/acorn), which has a modular architecture that allows extension of core functionality. The goal of Espree is to produce output that is similar to Esprima with a similar API so that it can be used in place of Esprima.
+
+## Usage
+
+Install:
+
+```
+npm i espree --save
+```
+
+And in your Node.js code:
+
+```javascript
+var espree = require("espree");
+
+var ast = espree.parse(code);
+```
+
+There is a second argument to `parse()` that allows you to specify various options:
+
+```javascript
+var espree = require("espree");
+
+// Optional second options argument with the following default settings
+var ast = espree.parse(code, {
+
+    // attach range information to each node
+    range: false,
+
+    // attach line/column location information to each node
+    loc: false,
+
+    // create a top-level comments array containing all comments
+    comment: false,
+
+    // attach comments to the closest relevant node as leadingComments and trailingComments
+    attachComment: false,
+
+    // create a top-level tokens array containing all tokens
+    tokens: false,
+
+    // Set to 3, 5 (default), 6, 7, 8, or 9 to specify the version of ECMAScript syntax you want to use.
+    // You can also set to 2015 (same as 6), 2016 (same as 7), 2017 (same as 8), or 2018 (same as 9) to use the year-based naming.
+    ecmaVersion: 5,
+
+    // specify which type of script you're parsing ("script" or "module")
+    sourceType: "script",
+
+    // specify additional language features
+    ecmaFeatures: {
+
+        // enable JSX parsing
+        jsx: false,
+
+        // enable return in global scope
+        globalReturn: false,
+
+        // enable implied strict mode (if ecmaVersion >= 5)
+        impliedStrict: false,
+
+        // allow experimental object rest/spread
+        experimentalObjectRestSpread: false
+    }
+});
+```
+
+## Esprima Compatibility Going Forward
+
+The primary goal is to produce the exact same AST structure and tokens as Esprima, and that takes precedence over anything else. (The AST structure being the [ESTree](https://github.com/estree/estree) API with JSX extensions.) Separate from that, Espree may deviate from what Esprima outputs in terms of where and how comments are attached, as well as what additional information is available on AST nodes. That is to say, Espree may add more things to the AST nodes than Esprima does but the overall AST structure produced will be the same.
+
+Espree may also deviate from Esprima in the interface it exposes.

+
+## Build Commands
+
+* `npm test` - run all linting and tests
+* `npm run lint` - run all linting
+* `npm run browserify` - creates a version of Espree that is usable in a browser
+
+## Differences from Espree 2.x
+
+* The `tokenize()` method does not use `ecmaFeatures`. Any string will be tokenized completely based on ECMAScript 6 semantics.
+* Trailing whitespace no longer is counted as part of a node.
+* `let` and `const` declarations are no longer parsed by default. You must opt-in by using an `ecmaVersion` newer than `5` or setting `sourceType` to `module`.
+* The `esparse` and `esvalidate` binary scripts have been removed.
+* There is no `tolerant` option. We will investigate adding this back in the future.
+
+## Known Incompatibilities
+
+In an effort to help those wanting to transition from other parsers to Espree, the following is a list of noteworthy incompatibilities with other parsers. These are known differences that we do not intend to change.
+
+### Esprima 1.2.2
+
+* Esprima counts trailing whitespace as part of each AST node while Espree does not. In Espree, the end of a node is where the last token occurs.
+* Espree does not parse `let` and `const` declarations by default.
+* Error messages returned for parsing errors are different.
+* There are two addition properties on every node and token: `start` and `end`. These represent the same data as `range` and are used internally by Acorn.
+
+### Esprima 2.x
+
+* Esprima 2.x uses a different comment attachment algorithm that results in some comments being added in different places than Espree. The algorithm Espree uses is the same one used in Esprima 1.2.2.
+
+## Frequently Asked Questions
+
+### Why another parser
+
+[ESLint](http://eslint.org) had been relying on Esprima as its parser from the beginning. While that was fine when the JavaScript language was evolving slowly, the pace of development increased dramatically and Esprima had fallen behind. ESLint, like many other tools reliant on Esprima, has been stuck in using new JavaScript language features until Esprima updates, and that caused our users frustration.
+
+We decided the only way for us to move forward was to create our own parser, bringing us inline with JSHint and JSLint, and allowing us to keep implementing new features as we need them. We chose to fork Esprima instead of starting from scratch in order to move as quickly as possible with a compatible API.
+
+With Espree 2.0.0, we are no longer a fork of Esprima but rather a translation layer between Acorn and Esprima syntax. This allows us to put work back into a community-supported parser (Acorn) that is continuing to grow and evolve while maintaining an Esprima-compatible parser for those utilities still built on Esprima.
+
+### Have you tried working with Esprima?
+
+Yes. Since the start of ESLint, we've regularly filed bugs and feature requests with Esprima and will continue to do so. However, there are some different philosophies around how the projects work that need to be worked through. The initial goal was to have Espree track Esprima and eventually merge the two back together, but we ultimately decided that building on top of Acorn was a better choice due to Acorn's plugin support.
+
+### Why don't you just use Acorn?
+
+Acorn is a great JavaScript parser that produces an AST that is compatible with Esprima. Unfortunately, ESLint relies on more than just the AST to do its job. It relies on Esprima's tokens and comment attachment features to get a complete picture of the source code. We investigated switching to Acorn, but the inconsistencies between Esprima and Acorn created too much work for a project like ESLint.
+
+We are building on top of Acorn, however, so that we can contribute back and help make Acorn even better.
+
+### What ECMAScript 6 features do you support?
+
+All of them.
+
+### What ECMAScript 7/2016 features do you support?
+
+There is only one ECMAScript 2016 syntax change: the exponentiation operator. Espree supports this.
+
+### What ECMAScript 2017 features do you support?
+
+There are two ECMAScript 2017 syntax changes: `async` functions, and trailing commas in function declarations and calls. Espree supports both of them.
+
+### What ECMAScript 2018 features do you support?
+
+Because ECMAScript 2018 is still under development, we are implementing features as they are finalized. Currently, Espree supports:
+
+* Invalid escape sequences in tagged template literals
+
+### How do you determine which experimental features to support?
+
+In general, we do not support experimental JavaScript features. We may make exceptions from time to time depending on the maturity of the features.

+[![Build Status](https://img.shields.io/travis/jquery/esprima/master.svg)](https://travis-ci.org/jquery/esprima)
+[![Coverage Status](https://img.shields.io/codecov/c/github/jquery/esprima/master.svg)](https://codecov.io/github/jquery/esprima)
+
+**Esprima** ([esprima.org](http://esprima.org), BSD license) is a high performance,
+standard-compliant [ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
+parser written in ECMAScript (also popularly known as
+[JavaScript](https://en.wikipedia.org/wiki/JavaScript)).
+Esprima is created and maintained by [Ariya Hidayat](https://twitter.com/ariyahidayat),
+with the help of [many contributors](https://github.com/jquery/esprima/contributors).
+
+### Features
+
+- Full support for ECMAScript 2017 ([ECMA-262 8th Edition](http://www.ecma-international.org/publications/standards/Ecma-262.htm))
+- Sensible [syntax tree format](https://github.com/estree/estree/blob/master/es5.md) as standardized by [ESTree project](https://github.com/estree/estree)
+- Experimental support for [JSX](https://facebook.github.io/jsx/), a syntax extension for [React](https://facebook.github.io/react/)
+- Optional tracking of syntax node location (index-based and line-column)
+- [Heavily tested](http://esprima.org/test/ci.html) (~1500 [unit tests](https://github.com/jquery/esprima/tree/master/test/fixtures) with [full code coverage](https://codecov.io/github/jquery/esprima))
+
+### API
+
+Esprima can be used to perform [lexical analysis](https://en.wikipedia.org/wiki/Lexical_analysis) (tokenization) or [syntactic analysis](https://en.wikipedia.org/wiki/Parsing) (parsing) of a JavaScript program.
+
+A simple example on Node.js REPL:
+
+```javascript
+> var esprima = require('esprima');
+> var program = 'const answer = 42';
+
+> esprima.tokenize(program);
+[ { type: 'Keyword', value: 'const' },
+  { type: 'Identifier', value: 'answer' },
+  { type: 'Punctuator', value: '=' },
+  { type: 'Numeric', value: '42' } ]
+  
+> esprima.parseScript(program);
+{ type: 'Program',
+  body:
+   [ { type: 'VariableDeclaration',
+       declarations: [Object],
+       kind: 'const' } ],
+  sourceType: 'script' }
+```
+
+For more information, please read the [complete documentation](http://esprima.org/doc).

+ESQuery is a library for querying the AST output by Esprima for patterns of syntax using a CSS style selector system. Check out the demo:
+
+[demo](https://estools.github.io/esquery/)
+
+The following selectors are supported:
+* AST node type: `ForStatement`
+* [wildcard](http://dev.w3.org/csswg/selectors4/#universal-selector): `*`
+* [attribute existence](http://dev.w3.org/csswg/selectors4/#attribute-selectors): `[attr]`
+* [attribute value](http://dev.w3.org/csswg/selectors4/#attribute-selectors): `[attr="foo"]` or `[attr=123]`
+* attribute regex: `[attr=/foo.*/]`
+* attribute conditons: `[attr!="foo"]`, `[attr>2]`, `[attr<3]`, `[attr>=2]`, or `[attr<=3]` 
+* nested attribute: `[attr.level2="foo"]`
+* field: `FunctionDeclaration > Identifier.id`
+* [First](http://dev.w3.org/csswg/selectors4/#the-first-child-pseudo) or [last](http://dev.w3.org/csswg/selectors4/#the-last-child-pseudo) child: `:first-child` or `:last-child`
+* [nth-child](http://dev.w3.org/csswg/selectors4/#the-nth-child-pseudo) (no ax+b support): `:nth-child(2)`
+* [nth-last-child](http://dev.w3.org/csswg/selectors4/#the-nth-last-child-pseudo) (no ax+b support): `:nth-last-child(1)`
+* [descendant](http://dev.w3.org/csswg/selectors4/#descendant-combinators): `ancestor descendant`
+* [child](http://dev.w3.org/csswg/selectors4/#child-combinators): `parent > child`
+* [following sibling](http://dev.w3.org/csswg/selectors4/#general-sibling-combinators): `node ~ sibling`
+* [adjacent sibling](http://dev.w3.org/csswg/selectors4/#adjacent-sibling-combinators): `node + adjacent`
+* [negation](http://dev.w3.org/csswg/selectors4/#negation-pseudo): `:not(ForStatement)`
+* [matches-any](http://dev.w3.org/csswg/selectors4/#matches): `:matches([attr] > :first-child, :last-child)`
+* [subject indicator](http://dev.w3.org/csswg/selectors4/#subject): `!IfStatement > [name="foo"]`
+* class of AST node: `:statement`, `:expression`, `:declaration`, `:function`, or `:pattern`

+### Esrecurse [![Build Status](https://travis-ci.org/estools/esrecurse.svg?branch=master)](https://travis-ci.org/estools/esrecurse)
+
+Esrecurse ([esrecurse](https://github.com/estools/esrecurse)) is
+[ECMAScript](https://www.ecma-international.org/publications/standards/Ecma-262.htm)
+recursive traversing functionality.
+
+### Example Usage
+
+The following code will output all variables declared at the root of a file.
+
+```javascript
+esrecurse.visit(ast, {
+    XXXStatement: function (node) {
+        this.visit(node.left);
+        // do something...
+        this.visit(node.right);
+    }
+});
+```
+
+We can use `Visitor` instance.
+
+```javascript
+var visitor = new esrecurse.Visitor({
+    XXXStatement: function (node) {
+        this.visit(node.left);
+        // do something...
+        this.visit(node.right);
+    }
+});
+
+visitor.visit(ast);
+```
+
+We can inherit `Visitor` instance easily.
+
+```javascript
+class Derived extends esrecurse.Visitor {
+    constructor()
+    {
+        super(null);
+    }
+
+    XXXStatement(node) {
+    }
+}
+
+```javascript
+function DerivedVisitor() {
+    esrecurse.Visitor.call(/* this for constructor */  this  /* visitor object automatically becomes this. */);
+}
+util.inherits(DerivedVisitor, esrecurse.Visitor);
+DerivedVisitor.prototype.XXXStatement = function (node) {
+    this.visit(node.left);
+    // do something...
+    this.visit(node.right);
+};
+```
+
+And you can invoke default visiting operation inside custom visit operation.
+
+```javascript
+function DerivedVisitor() {
+    esrecurse.Visitor.call(/* this for constructor */  this  /* visitor object automatically becomes this. */);
+}
+util.inherits(DerivedVisitor, esrecurse.Visitor);
+DerivedVisitor.prototype.XXXStatement = function (node) {
+    // do something...
+    this.visitChildren(node);
+};
+```
+
+The `childVisitorKeys` option does customize the behavoir of `this.visitChildren(node)`.
+We can use user-defined node types.
+
+```javascript
+// This tree contains a user-defined `TestExpression` node.
+var tree = {
+    type: 'TestExpression',
+
+    // This 'argument' is the property containing the other **node**.
+    argument: {
+        type: 'Literal',
+        value: 20
+    },
+
+    // This 'extended' is the property not containing the other **node**.
+    extended: true
+};
+esrecurse.visit(
+    ast,
+    {
+        Literal: function (node) {
+            // do something...
+        }
+    },
+    {
+        // Extending the existing traversing rules.
+        childVisitorKeys: {
+            // TargetNodeName: [ 'keys', 'containing', 'the', 'other', '**node**' ]
+            TestExpression: ['argument']
+        }
+    }
+);
+```
+
+We can use the `fallback` option as well.
+If the `fallback` option is `"iteration"`, `esrecurse` would visit all enumerable properties of unknown nodes.
+Please note circular references cause the stack overflow. AST might have circular references in additional properties for some purpose (e.g. `node.parent`).
+
+```javascript
+esrecurse.visit(
+    ast,
+    {
+        Literal: function (node) {
+            // do something...
+        }
+    },
+    {
+        fallback: 'iteration'
+    }
+);
+```
+
+If the `fallback` option is a function, `esrecurse` calls this function to determine the enumerable properties of unknown nodes.
+Please note circular references cause the stack overflow. AST might have circular references in additional properties for some purpose (e.g. `node.parent`).
+
+```javascript
+esrecurse.visit(
+    ast,
+    {
+        Literal: function (node) {
+            // do something...
+        }
+    },
+    {
+        fallback: function (node) {
+            return Object.keys(node).filter(function(key) {
+                return key !== 'argument'
+            });
+        }
+    }
+);
+```

+### esutils [![Build Status](https://secure.travis-ci.org/estools/esutils.svg)](http://travis-ci.org/estools/esutils)
+esutils ([esutils](http://github.com/estools/esutils)) is
+utility box for ECMAScript language tools.
+
+### API
+
+### ast
+
+#### ast.isExpression(node)
+
+Returns true if `node` is an Expression as defined in ECMA262 edition 5.1 section
+[11](https://es5.github.io/#x11).
+
+#### ast.isStatement(node)
+
+Returns true if `node` is a Statement as defined in ECMA262 edition 5.1 section
+[12](https://es5.github.io/#x12).
+
+#### ast.isIterationStatement(node)
+
+Returns true if `node` is an IterationStatement as defined in ECMA262 edition
+5.1 section [12.6](https://es5.github.io/#x12.6).
+
+#### ast.isSourceElement(node)
+
+Returns true if `node` is a SourceElement as defined in ECMA262 edition 5.1
+section [14](https://es5.github.io/#x14).
+
+#### ast.trailingStatement(node)
+
+Returns `Statement?` if `node` has trailing `Statement`.
+```js
+if (cond)
+    consequent;
+```
+When taking this `IfStatement`, returns `consequent;` statement.
+
+#### ast.isProblematicIfStatement(node)
+
+Returns true if `node` is a problematic IfStatement. If `node` is a problematic `IfStatement`, `node` cannot be represented as an one on one JavaScript code.
+```js
+{
+    type: 'IfStatement',
+    consequent: {
+        type: 'WithStatement',
+        body: {
+            type: 'IfStatement',
+            consequent: {type: 'EmptyStatement'}
+        }
+    },
+    alternate: {type: 'EmptyStatement'}
+}
+```
+The above node cannot be represented as a JavaScript code, since the top level `else` alternate belongs to an inner `IfStatement`.
+
+
+### code
+
+#### code.isDecimalDigit(code)
+
+Return true if provided code is decimal digit.
+
+#### code.isHexDigit(code)
+
+Return true if provided code is hexadecimal digit.
+
+#### code.isOctalDigit(code)
+
+Return true if provided code is octal digit.
+
+#### code.isWhiteSpace(code)
+
+Return true if provided code is white space. White space characters are formally defined in ECMA262.
+
+#### code.isLineTerminator(code)
+
+Return true if provided code is line terminator. Line terminator characters are formally defined in ECMA262.
+
+#### code.isIdentifierStart(code)
+
+Return true if provided code can be the first character of ECMA262 Identifier. They are formally defined in ECMA262.
+
+#### code.isIdentifierPart(code)
+
+Return true if provided code can be the trailing character of ECMA262 Identifier. They are formally defined in ECMA262.
+
+### keyword
+
+#### keyword.isKeywordES5(id, strict)
+
+Returns `true` if provided identifier string is a Keyword or Future Reserved Word
+in ECMA262 edition 5.1. They are formally defined in ECMA262 sections
+[7.6.1.1](http://es5.github.io/#x7.6.1.1) and [7.6.1.2](http://es5.github.io/#x7.6.1.2),
+respectively. If the `strict` flag is truthy, this function additionally checks whether
+`id` is a Keyword or Future Reserved Word under strict mode.
+
+#### keyword.isKeywordES6(id, strict)
+
+Returns `true` if provided identifier string is a Keyword or Future Reserved Word
+in ECMA262 edition 6. They are formally defined in ECMA262 sections
+[11.6.2.1](https://people.mozilla.org/~jorendorff/es6-draft.html#sec-keywords) and
+[11.6.2.2](https://people.mozilla.org/~jorendorff/es6-draft.html#sec-future-reserved-words),
+respectively. If the `strict` flag is truthy, this function additionally checks whether
+`id` is a Keyword or Future Reserved Word under strict mode.
+
+#### keyword.isReservedWordES5(id, strict)
+
+Returns `true` if provided identifier string is a Reserved Word in ECMA262 edition 5.1.
+They are formally defined in ECMA262 section [7.6.1](http://es5.github.io/#x7.6.1).
+If the `strict` flag is truthy, this function additionally checks whether `id`
+is a Reserved Word under strict mode.
+
+#### keyword.isReservedWordES6(id, strict)
+
+Returns `true` if provided identifier string is a Reserved Word in ECMA262 edition 6.
+They are formally defined in ECMA262 section [11.6.2](https://people.mozilla.org/~jorendorff/es6-draft.html#sec-reserved-words).
+If the `strict` flag is truthy, this function additionally checks whether `id`
+is a Reserved Word under strict mode.
+
+#### keyword.isRestrictedWord(id)
+
+Returns `true` if provided identifier string is one of `eval` or `arguments`.
+They are restricted in strict mode code throughout ECMA262 edition 5.1 and
+in ECMA262 edition 6 section [12.1.1](https://people.mozilla.org/~jorendorff/es6-draft.html#sec-identifiers-static-semantics-early-errors).
+
+#### keyword.isIdentifierName(id)
+
+Return true if provided identifier string is an IdentifierName as specified in
+ECMA262 edition 5.1 section [7.6](https://es5.github.io/#x7.6).
+
+#### keyword.isIdentifierES5(id, strict)
+
+Return true if provided identifier string is an Identifier as specified in
+ECMA262 edition 5.1 section [7.6](https://es5.github.io/#x7.6). If the `strict`
+flag is truthy, this function additionally checks whether `id` is an Identifier
+under strict mode.
+
+#### keyword.isIdentifierES6(id, strict)
+
+Return true if provided identifier string is an Identifier as specified in
+ECMA262 edition 6 section [12.1](https://people.mozilla.org/~jorendorff/es6-draft.html#sec-identifiers).
+If the `strict` flag is truthy, this function additionally checks whether `id`
+is an Identifier under strict mode.

+# extend() for Node.js <sup>[![Version Badge][npm-version-png]][npm-url]</sup>
+
+`node-extend` is a port of the classic extend() method from jQuery. It behaves as you expect. It is simple, tried and true.
+
+Notes:
+
+* Since Node.js >= 4,
+  [`Object.assign`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/assign)
+  now offers the same functionality natively (but without the "deep copy" option).
+  See [ECMAScript 2015 (ES6) in Node.js](https://nodejs.org/en/docs/es6).
+* Some native implementations of `Object.assign` in both Node.js and many
+  browsers (since NPM modules are for the browser too) may not be fully
+  spec-compliant.
+  Check [`object.assign`](https://www.npmjs.com/package/object.assign) module for
+  a compliant candidate.
+
+## Installation
+
+This package is available on [npm][npm-url] as: `extend`
+
+``` sh
+npm install extend
+```
+
+## Usage
+
+**Syntax:** extend **(** [`deep`], `target`, `object1`, [`objectN`] **)**
+
+*Extend one object with one or more others, returning the modified object.*
+
+**Example:**
+
+``` js
+var extend = require('extend');
+extend(targetObject, object1, object2);
+```
+
+Keep in mind that the target object will be modified, and will be returned from extend().
+
+If a boolean true is specified as the first argument, extend performs a deep copy, recursively copying any objects it finds. Otherwise, the copy will share structure with the original object(s).
+Undefined properties are not copied. However, properties inherited from the object's prototype will be copied over.
+Warning: passing `false` as the first argument is not supported.
+
+### Arguments
+
+* `deep` *Boolean* (optional)
+If set, the merge becomes recursive (i.e. deep copy).
+* `target`	*Object*
+The object to extend.
+* `object1`	*Object*
+The object that will be merged into the first.
+* `objectN` *Object* (Optional)
+More objects to merge into the first.
+
+## License
+
+`node-extend` is licensed under the [MIT License][mit-license-url].
+
+## Acknowledgements
+
+All credit to the jQuery authors for perfecting this amazing utility.

+
+
+A node module to edit a string with a users preferred text editor using $VISUAL or $ENVIRONMENT.
+
+Version: 2.1.0
+
+As of version 2.0.0, node 0.10 is no longer support. Minimum node version is now 0.12.
+
+## Install
+
+`npm install external-editor --save`
+
+## Usage
+
+A simple example using the `.edit` convenience method
+
+    var ExternalEditor = require('external-editor')
+    var data = ExternalEditor.edit('\n\n# Please write your text above');
+    console.log(data);
+
+A full featured example
+
+    var ExternalEditor = require('external-editor');
+    
+    try {
+        var editor = new ExternalEditor();
+        var text = editor.run()
+        // the text is also available in editor.text
+    } catch (err) {
+        if (err instanceOf ExternalEditor.CreateFileError) {
+            console.log('Failed to create the temporary file');
+        } else if (err instanceOf ExternalEditor.ReadFileError) {
+            console.log('Failed to read the temporary file');
+        } else if (err instanceOf ExternalEditor.LaunchEditorError) {
+            console.log('Failed to launch your editor');
+        } else {
+            throw err;
+        }
+    }
+    
+    // Do things with the text
+    
+    // Eventually call the cleanup to remove the temporary file
+    try {
+        editor.cleanup();   
+    } catch (err) {
+         if (err instanceOf ExternalEditor.RemoveFileError) {
+             console.log('Failed to remove the temporary file');
+         } else {
+            throw err
+        }
+    }
+    
+    
+#### API
+**Static Methods**
+
+- `edit(text)`
+    - `text` (string) *Optional* Defaults to empty string
+    - **Returns** (string) The contents of the file
+    - Could throw `CreateFileError`, `ReadFileError`, or `LaunchEditorError`, or `RemoveFileError`
+- `editAsync(text, callback)`
+    - `text` (string) *Optional* Defaults to empty string
+    - `callback` (function (error, text))
+        - `error` could be of type `CreateFileError`, `ReadFileError`, or `LaunchEditorError`, or `RemoveFileError`
+        - `text`(string) The contents of the file     
+
+
+**Static Properties**
+
+- `CreateFileError` Error thrown if the temporary file could not be created. 
+- `ReadFileError` Error thrown if the temporary file could not be read.
+- `RemoveFileError` Error thrown if the temporary file could not be removed during cleanup.
+- `LaunchEditorError` Error thrown if the editor could not be launched.
+
+**Public Methods**
+
+- `new ExternalEditor(text)`
+    - `text` (string) *Optional* Defaults to empty string
+    - Could throw `CreateFileError`
+- `run()` Launches the editor.
+    - **Returns** (string) The contents of the file
+    - Could throw `LaunchEditorError` or `ReadFileError`
+- `runAsync(callback)` Launches the editor in an async way
+    - `callback` (function (error, text))
+        - `error` could be of type `ReadFileError` or `LaunchEditorError`
+        - `text`(string) The contents of the file
+- `cleanup()`  Removes the temporary file.
+    - Could throw `RemoveFileError`
+    
+**Public Properties**
+
+- `text` (string) *readonly* The text in the temporary file.
+- `editor.bin` (string) The editor determined from the environment.
+- `editor.args` (array) Default arguments for the bin
+- `temp_file` (string) Path to temporary file. Can be changed, but be careful as the temporary file probably already 
+    exists and would need be removed manually.
+    
+## Errors
+
+All errors have a simple message explaining what went wrong. They all also have an `original_error` property containing
+the original error thrown for debugging purposes.
+    
+## Why Synchronous?
+ 
+Everything is synchronous to make sure the editor has complete control of the stdin and stdout. Testing has shown 
+async launching of the editor can lead to issues when using readline or other packages which try to read from stdin or 
+write to stdout. Seeing as this will be used in an interactive CLI environment, I made the decision to force the package
+to be synchronous. If you know a reliable way to force all stdin and stdout to be limited only to the child_process,
+please submit a PR.
+
+If async is really needed, you can use `editAsync` or `runAsync`. If you are using readline or have anything else
+listening to the stdin or you write to stdout, you will most likely have problem, so make sure to remove any other 
+listeners on stdin, stdout, or stdin.

+# fast-json-stable-stringify
+
+Deterministic `JSON.stringify()` - a faster version of [@substack](https://github.com/substack)'s json-stable-strigify without [jsonify](https://github.com/substack/jsonify).
+
+You can also pass in a custom comparison function.
+
+[![Build Status](https://travis-ci.org/epoberezkin/fast-json-stable-stringify.svg?branch=master)](https://travis-ci.org/epoberezkin/fast-json-stable-stringify)
+[![Coverage Status](https://coveralls.io/repos/github/epoberezkin/fast-json-stable-stringify/badge.svg?branch=master)](https://coveralls.io/github/epoberezkin/fast-json-stable-stringify?branch=master)
+
+# example
+
+``` js
+var stringify = require('fast-json-stable-stringify');
+var obj = { c: 8, b: [{z:6,y:5,x:4},7], a: 3 };
+console.log(stringify(obj));
+```
+
+output:
+
+```
+{"a":3,"b":[{"x":4,"y":5,"z":6},7],"c":8}
+```
+
+
+# methods
+
+``` js
+var stringify = require('fast-json-stable-stringify')
+```
+
+## var str = stringify(obj, opts)
+
+Return a deterministic stringified string `str` from the object `obj`.
+
+
+## options
+
+### cmp
+
+If `opts` is given, you can supply an `opts.cmp` to have a custom comparison
+function for object keys. Your function `opts.cmp` is called with these
+parameters:
+
+``` js
+opts.cmp({ key: akey, value: avalue }, { key: bkey, value: bvalue })
+```
+
+For example, to sort on the object key names in reverse order you could write:
+
+``` js
+var stringify = require('fast-json-stable-stringify');
+
+var obj = { c: 8, b: [{z:6,y:5,x:4},7], a: 3 };
+var s = stringify(obj, function (a, b) {
+    return a.key < b.key ? 1 : -1;
+});
+console.log(s);
+```
+
+which results in the output string:
+
+```
+{"c":8,"b":[{"z":6,"y":5,"x":4},7],"a":3}
+```
+
+Or if you wanted to sort on the object values in reverse order, you could write:
+
+```
+var stringify = require('fast-json-stable-stringify');
+
+var obj = { d: 6, c: 5, b: [{z:3,y:2,x:1},9], a: 10 };
+var s = stringify(obj, function (a, b) {
+    return a.value < b.value ? 1 : -1;
+});
+console.log(s);
+```
+
+which outputs:
+
+```
+{"d":6,"c":5,"b":[{"z":3,"y":2,"x":1},9],"a":10}
+```
+
+### cycles
+
+Pass `true` in `opts.cycles` to stringify circular property as `__cycle__` - the result will not be a valid JSON string in this case.
+
+TypeError will be thrown in case of circular object without this option.
+
+
+# install
+
+With [npm](https://npmjs.org) do:
+
+```
+npm install fast-json-stable-stringify
+```
+
+
+# benchmark
+
+To run benchmark (requires Node.js 6+):
+```
+node benchmark
+```
+
+Results:
+```
+fast-json-stable-stringify x 17,189 ops/sec ±1.43% (83 runs sampled)
+json-stable-stringify x 13,634 ops/sec ±1.39% (85 runs sampled)

+# fast-levenshtein - Levenshtein algorithm in Javascript
+
+[![Build Status](https://secure.travis-ci.org/hiddentao/fast-levenshtein.png)](http://travis-ci.org/hiddentao/fast-levenshtein)
+[![NPM module](https://badge.fury.io/js/fast-levenshtein.png)](https://badge.fury.io/js/fast-levenshtein)
+[![NPM downloads](https://img.shields.io/npm/dm/fast-levenshtein.svg?maxAge=2592000)](https://www.npmjs.com/package/fast-levenshtein)
+[![Follow on Twitter](https://img.shields.io/twitter/url/http/shields.io.svg?style=social&label=Follow&maxAge=2592000)](https://twitter.com/hiddentao)
+
+An efficient Javascript implementation of the [Levenshtein algorithm](http://en.wikipedia.org/wiki/Levenshtein_distance) with locale-specific collator support.
+
+## Features
+
+* Works in node.js and in the browser.
+* Better performance than other implementations by not needing to store the whole matrix ([more info](http://www.codeproject.com/Articles/13525/Fast-memory-efficient-Levenshtein-algorithm)).
+* Locale-sensitive string comparisions if needed.
+* Comprehensive test suite and performance benchmark.
+* Small: <1 KB minified and gzipped
+
+## Installation
+
+### node.js
+
+Install using [npm](http://npmjs.org/):
+
+```bash
+$ npm install fast-levenshtein
+```
+
+### Browser
+
+Using bower:
+
+```bash
+$ bower install fast-levenshtein
+```
+
+If you are not using any module loader system then the API will then be accessible via the `window.Levenshtein` object.
+
+## Examples
+
+**Default usage**
+
+```javascript
+var levenshtein = require('fast-levenshtein');
+
+var distance = levenshtein.get('back', 'book');   // 2
+var distance = levenshtein.get('我愛你', '我叫你');   // 1
+```
+
+**Locale-sensitive string comparisons**
+
+It supports using [Intl.Collator](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Collator) for locale-sensitive  string comparisons:
+
+```javascript
+var levenshtein = require('fast-levenshtein');
+
+levenshtein.get('mikailovitch', 'Mikhaïlovitch', { useCollator: true});
+// 1
+```
+
+## Building and Testing
+
+To build the code and run the tests:
+
+```bash
+$ npm install -g grunt-cli
+$ npm install
+$ npm run build
+```
+
+## Performance
+
+_Thanks to [Titus Wormer](https://github.com/wooorm) for [encouraging me](https://github.com/hiddentao/fast-levenshtein/issues/1) to do this._
+
+Benchmarked against other node.js levenshtein distance modules (on Macbook Air 2012, Core i7, 8GB RAM):
+
+```bash
+Running suite Implementation comparison [benchmark/speed.js]...
+>> levenshtein-edit-distance x 234 ops/sec ±3.02% (73 runs sampled)
+>> levenshtein-component x 422 ops/sec ±4.38% (83 runs sampled)
+>> levenshtein-deltas x 283 ops/sec ±3.83% (78 runs sampled)
+>> natural x 255 ops/sec ±0.76% (88 runs sampled)
+>> levenshtein x 180 ops/sec ±3.55% (86 runs sampled)
+>> fast-levenshtein x 1,792 ops/sec ±2.72% (95 runs sampled)
+Benchmark done.
+Fastest test is fast-levenshtein at 4.2x faster than levenshtein-component
+```
+
+You can run this benchmark yourself by doing:
+
+```bash
+$ npm install
+$ npm run build
+$ npm run benchmark
+```
+
+## Contributing

+# file-entry-cache
+> Super simple cache for file metadata, useful for process that work o a given series of files
+> and that only need to repeat the job on the changed ones since the previous run of the process — Edit
+
+[![NPM Version](http://img.shields.io/npm/v/file-entry-cache.svg?style=flat)](https://npmjs.org/package/file-entry-cache)
+[![Build Status](http://img.shields.io/travis/royriojas/file-entry-cache.svg?style=flat)](https://travis-ci.org/royriojas/file-entry-cache)
+
+## install
+
+```bash
+npm i --save file-entry-cache
+```
+
+## Usage
+
+```js
+// loads the cache, if one does not exists for the given
+// Id a new one will be prepared to be created
+var fileEntryCache = require('file-entry-cache');
+
+var cache = fileEntryCache.create('testCache');
+
+var files = expand('../fixtures/*.txt');
+
+// the first time this method is called, will return all the files
+var oFiles = cache.getUpdatedFiles(files);
+
+// this will persist this to disk checking each file stats and
+// updating the meta attributes `size` and `mtime`.
+// custom fields could also be added to the meta object and will be persisted
+// in order to retrieve them later
+cache.reconcile();
+
+// use this if you want the non visited file entries to be kept in the cache
+// for more than one execution
+//
+// cache.reconcile( true /* noPrune */)
+
+// on a second run
+var cache2 = fileEntryCache.create('testCache');
+
+// will return now only the files that were modified or none
+// if no files were modified previous to the execution of this function
+var oFiles = cache.getUpdatedFiles(files);
+
+// if you want to prevent a file from being considered non modified
+// something useful if a file failed some sort of validation
+// you can then remove the entry from the cache doing
+cache.removeEntry('path/to/file'); // path to file should be the same path of the file received on `getUpdatedFiles`
+// that will effectively make the file to appear again as modified until the validation is passed. In that
+// case you should not remove it from the cache
+
+// if you need all the files, so you can determine what to do with the changed ones
+// you can call
+var oFiles = cache.normalizeEntries(files);
+
+// oFiles will be an array of objects like the following
+entry = {
+  key: 'some/name/file', the path to the file
+  changed: true, // if the file was changed since previous run
+  meta: {
+    size: 3242, // the size of the file
+    mtime: 231231231, // the modification time of the file
+    data: {} // some extra field stored for this file (useful to save the result of a transformation on the file
+  }
+}
+
+```
+
+## Motivation for this module
+
+I needed a super simple and dumb **in-memory cache** with optional disk persistence (write-back cache) in order to make
+a script that will beautify files with `esformatter` to execute only on the files that were changed since the last run.
+
+In doing so the process of beautifying files was reduced from several seconds to a small fraction of a second.
+
+This module uses [flat-cache](https://www.npmjs.com/package/flat-cache) a super simple `key/value` cache storage with
+optional file persistance.
+
+The main idea is to read the files when the task begins, apply the transforms required, and if the process succeed,
+then store the new state of the files. The next time this module request for `getChangedFiles` will return only
+the files that were modified. Making the process to end faster.
+
+This module could also be used by processes that modify the files applying a transform, in that case the result of the
+transform could be stored in the `meta` field, of the entries. Anything added to the meta field will be persisted.
+Those processes won't need to call `getChangedFiles` they will instead call `normalizeEntries` that will return the
+entries with a `changed` field that can be used to determine if the file was changed or not. If it was not changed
+the transformed stored data could be used instead of actually applying the transformation, saving time in case of only
+a few files changed.
+
+In the worst case scenario all the files will be processed. In the best case scenario only a few of them will be processed.
+
+## Important notes
+- The values set on the meta attribute of the entries should be `stringify-able` ones if possible, flat-cache uses `circular-json` to try to persist circular structures, but this should be considered experimental. The best results are always obtained with non circular values
+- All the changes to the cache state are done to memory first and only persisted after reconcile.
+- By default non visited entries are removed from the cache. This is done to prevent the file from growing too much. If this is not an issue and
+  you prefer to do a manual pruning of the cache files, you can pass `true` to the `reconcile` call. Like this:
+
+  ```javascript
+  cache.reconcile( true /* noPrune */ );
+  ```

+# flat-cache
+> A stupidly simple key/value storage using files to persist the data
+
+[![NPM Version](http://img.shields.io/npm/v/flat-cache.svg?style=flat)](https://npmjs.org/package/flat-cache)
+[![Build Status](http://img.shields.io/travis/royriojas/flat-cache.svg?style=flat)](https://travis-ci.org/royriojas/flat-cache)
+
+## install
+
+```bash
+npm i --save flat-cache
+```
+
+## Usage
+
+```js
+var flatCache = require('flat-cache')
+// loads the cache, if one does not exists for the given
+// Id a new one will be prepared to be created
+var cache = flatCache.load('cacheId');
+
+// sets a key on the cache
+cache.setKey('key', { foo: 'var' });
+
+// get a key from the cache
+cache.getKey('key') // { foo: 'var' }
+
+// fetch the entire persisted object
+cache.all() // { 'key': { foo: 'var' } }
+
+// remove a key
+cache.removeKey('key'); // removes a key from the cache
+
+// save it to disk
+cache.save(); // very important, if you don't save no changes will be persisted.
+// cache.save( true /* noPrune */) // can be used to prevent the removal of non visited keys
+
+// loads the cache from a given directory, if one does
+// not exists for the given Id a new one will be prepared to be created
+var cache = flatCache.load('cacheId', path.resolve('./path/to/folder'));
+
+// The following methods are useful to clear the cache
+// delete a given cache
+flatCache.clearCacheById('cacheId') // removes the cacheId document if one exists.
+
+// delete all cache
+flatCache.clearAll(); // remove the cache directory
+```
+
+## Motivation for this module
+
+I needed a super simple and dumb **in-memory cache** with optional disk persistance in order to make
+a script that will beutify files with `esformatter` only execute on the files that were changed since the last run.
+To make that possible we need to store the `fileSize` and `modificationTime` of the files. So a simple `key/value`
+storage was needed and Bam! this module was born.
+
+## Important notes
+- If no directory is especified when the `load` method is called, a folder named `.cache` will be created
+  inside the module directory when `cache.save` is called. If you're committing your `node_modules` to any vcs, you
+  might want to ignore the default `.cache` folder, or specify a custom directory.
+- The values set on the keys of the cache should be `stringify-able` ones, meaning no circular references
+- All the changes to the cache state are done to memory
+- I could have used a timer or `Object.observe` to deliver the changes to disk, but I wanted to keep this module
+  intentionally dumb and simple
+- Non visited keys are removed when `cache.save()` is called. If this is not desired, you can pass `true` to the save call
+  like: `cache.save( true /* noPrune */ )`.

+# flat-cache - Changelog
+## v1.3.0
+- **Other changes**
+  - Added #all method ([#16](https://github.com/royriojas/flat-cache/issues/16)) - [12293be]( https://github.com/royriojas/flat-cache/commit/12293be ), [Ozair Patel](https://github.com/Ozair Patel), 25/09/2017 16:46:38
+
+    * Added #all method

+    

+    * Added #all method test

+    

+    * Updated readme

+    

+    * Added yarn.lock

+    

+    * Added more keys for #all test

+    

+    * Beautified file

+    
+  - fix changelog title style ([#14](https://github.com/royriojas/flat-cache/issues/14)) - [af8338a]( https://github.com/royriojas/flat-cache/commit/af8338a ), [前端小武](https://github.com/前端小武), 19/12/2016 23:34:48
+
+    
+## v1.2.2
+- **Bug Fixes**
+  - Do not crash if cache file is invalid JSON. ([#13](https://github.com/royriojas/flat-cache/issues/13)) - [87beaa6]( https://github.com/royriojas/flat-cache/commit/87beaa6 ), [Roy Riojas](https://github.com/Roy Riojas), 19/12/2016 21:03:35
+
+    Fixes <a target="_blank" class="info-link" href="https://github.com/royriojas/flat-cache/issues/12"><span>#12</span></a>

+    

+    Not sure under which situations a cache file might exist that does

+    not contain a valid JSON structure, but just in case to cover

+    the possibility of this happening a try catch block has been added

+    

+    If the cache is somehow not valid the cache will be discarded an a

+    a new cache will be stored instead
+- **Other changes**
+  - Added travis ci support for modern node versions ([#11](https://github.com/royriojas/flat-cache/issues/11)) - [1c2b1f7]( https://github.com/royriojas/flat-cache/commit/1c2b1f7 ), [Amila Welihinda](https://github.com/Amila Welihinda), 11/11/2016 02:47:52
+
+    
+  - Bumping `circular-son` version ([#10](https://github.com/royriojas/flat-cache/issues/10)) - [4d5e861]( https://github.com/royriojas/flat-cache/commit/4d5e861 ), [Andrea Giammarchi](https://github.com/Andrea Giammarchi), 02/08/2016 09:13:52
+
+    As mentioned in https://github.com/WebReflection/circular-json/issues/25 `circular-json` wan't rightly implementing the license field.

+    

+    Latest version bump changed only that bit so that ESLint should now be happy.
+## v1.2.1
+- **Bug Fixes**
+  - Add missing utils.js file to the package. closes [#8](https://github.com/royriojas/flat-cache/issues/8) - [ec10cf2]( https://github.com/royriojas/flat-cache/commit/ec10cf2 ), [Roy Riojas](https://github.com/Roy Riojas), 01/08/2016 04:18:57

+
+    Since we control both writing and reading of JSON stream, there no needs 
+    to handle unicode BOM.
+  - Use circular-json to handle circular references (fix [#5](https://github.com/royriojas/flat-cache/issues/5)) - [cd7aeed]( https://github.com/royriojas/flat-cache/commit/cd7aeed ), [Jean Ponchon](https://github.com/Jean Ponchon), 25/07/2016 13:11:59

+# fs.realpath
+
+A backwards-compatible fs.realpath for Node v6 and above
+
+In Node v6, the JavaScript implementation of fs.realpath was replaced
+with a faster (but less resilient) native implementation.  That raises
+new and platform-specific errors and cannot handle long or excessively
+symlink-looping paths.
+
+This module handles those cases by detecting the new errors and
+falling back to the JavaScript implementation.  On versions of Node
+prior to v6, it has no effect.
+
+## USAGE
+
+```js
+var rp = require('fs.realpath')
+
+// async version
+rp.realpath(someLongAndLoopingPath, function (er, real) {
+  // the ELOOP was handled, but it was a bit slower
+})
+
+// sync version
+var real = rp.realpathSync(someLongAndLoopingPath)
+
+// monkeypatch at your own risk!
+// This replaces the fs.realpath/fs.realpathSync builtins
+rp.monkeypatch()
+
+// un-do the monkeypatching
+rp.unmonkeypatch()
+```

+functional-red-black-tree
+=========================
+A [fully persistent](http://en.wikipedia.org/wiki/Persistent_data_structure) [red-black tree](http://en.wikipedia.org/wiki/Red%E2%80%93black_tree) written 100% in JavaScript.  Works both in node.js and in the browser via [browserify](http://browserify.org/).
+
+Functional (or fully presistent) data structures allow for non-destructive updates.  So if you insert an element into the tree, it returns a new tree with the inserted element rather than destructively updating the existing tree in place.  Doing this requires using extra memory, and if one were naive it could cost as much as reallocating the entire tree.  Instead, this data structure saves some memory by recycling references to previously allocated subtrees.  This requires using only O(log(n)) additional memory per update instead of a full O(n) copy.
+
+Some advantages of this is that it is possible to apply insertions and removals to the tree while still iterating over previous versions of the tree.  Functional and persistent data structures can also be useful in many geometric algorithms like point location within triangulations or ray queries, and can be used to analyze the history of executing various algorithms.  This added power though comes at a cost, since it is generally a bit slower to use a functional data structure than an imperative version.  However, if your application needs this behavior then you may consider using this module.
+
+# Install
+
+    npm install functional-red-black-tree
+
+# Example
+
+Here is an example of some basic usage:
+
+```javascript
+//Load the library
+var createTree = require("functional-red-black-tree")
+
+//Create a tree
+var t1 = createTree()
+
+//Insert some items into the tree
+var t2 = t1.insert(1, "foo")
+var t3 = t2.insert(2, "bar")
+
+//Remove something
+var t4 = t3.remove(1)
+```
+
+
+# API
+
+```javascript
+var createTree = require("functional-red-black-tree")
+```

+## Tree methods
+
+### `var tree = createTree([compare])`
+Creates an empty functional tree
+
+* `compare` is an optional comparison function, same semantics as array.sort()
+
+**Returns** An empty tree ordered by `compare`
+
+### `tree.keys`
+A sorted array of all the keys in the tree
+
+### `tree.values`
+An array array of all the values in the tree
+
+### `tree.length`
+The number of items in the tree
+
+### `tree.get(key)`
+Retrieves the value associated to the given key
+
+* `key` is the key of the item to look up
+
+**Returns** The value of the first node associated to `key`
+
+### `tree.insert(key, value)`
+Creates a new tree with the new pair inserted.
+
+* `key` is the key of the item to insert
+* `value` is the value of the item to insert
+
+**Returns** A new tree with `key` and `value` inserted
+
+### `tree.remove(key)`
+Removes the first item with `key` in the tree
+
+* `key` is the key of the item to remove
+
+**Returns** A new tree with the given item removed if it exists
+
+### `tree.find(key)`
+Returns an iterator pointing to the first item in the tree with `key`, otherwise `null`.
+
+### `tree.ge(key)`
+Find the first item in the tree whose key is `>= key`
+
+* `key` is the key to search for
+
+**Returns** An iterator at the given element.
+
+### `tree.gt(key)`
+Finds the first item in the tree whose key is `> key`
+
+* `key` is the key to search for
+
+**Returns** An iterator at the given element
+
+### `tree.lt(key)`
+Finds the last item in the tree whose key is `< key`
+
+* `key` is the key to search for
+
+**Returns** An iterator at the given element
+
+### `tree.le(key)`
+Finds the last item in the tree whose key is `<= key`
+
+* `key` is the key to search for
+
+**Returns** An iterator at the given element
+
+### `tree.at(position)`
+Finds an iterator starting at the given element
+
+* `position` is the index at which the iterator gets created
+
+**Returns** An iterator starting at position
+
+### `tree.begin`
+An iterator pointing to the first element in the tree
+
+### `tree.end`
+An iterator pointing to the last element in the tree
+
+### `tree.forEach(visitor(key,value)[, lo[, hi]])`
+Walks a visitor function over the nodes of the tree in order.
+
+* `visitor(key,value)` is a callback that gets executed on each node.  If a truthy value is returned from the visitor, then iteration is stopped.
+* `lo` is an optional start of the range to visit (inclusive)
+* `hi` is an optional end of the range to visit (non-inclusive)
+
+**Returns** The last value returned by the callback
+
+### `tree.root`
+Returns the root node of the tree
+
+
+## Node properties
+Each node of the tree has the following properties:
+
+### `node.key`
+The key associated to the node
+
+### `node.value`
+The value associated to the node
+
+### `node.left`
+The left subtree of the node
+
+### `node.right`

+### `iter.key`
+The key of the item referenced by the iterator
+
+### `iter.value`
+The value of the item referenced by the iterator
+
+### `iter.node`
+The value of the node at the iterator's current position.  `null` is iterator is node valid.

+
+### `iter.remove()`
+Removes the item at the position of the iterator
+
+**Returns** A new binary search tree with `iter`'s item removed
+
+### `iter.update(value)`

+
+**Returns** A new binary search tree with the corresponding node updated
+
+### `iter.next()`
+Advances the iterator to the next position
+
+### `iter.prev()`
+Moves the iterator backward one element
+
+### `iter.hasNext`
+If true, then the iterator is not at the end of the sequence
+
+### `iter.hasPrev`

+# Glob
+
+Match files using the patterns the shell uses, like stars and stuff.
+
+[![Build Status](https://travis-ci.org/isaacs/node-glob.svg?branch=master)](https://travis-ci.org/isaacs/node-glob/) [![Build Status](https://ci.appveyor.com/api/projects/status/kd7f3yftf7unxlsx?svg=true)](https://ci.appveyor.com/project/isaacs/node-glob) [![Coverage Status](https://coveralls.io/repos/isaacs/node-glob/badge.svg?branch=master&service=github)](https://coveralls.io/github/isaacs/node-glob?branch=master)
+
+This is a glob implementation in JavaScript.  It uses the `minimatch`
+library to do its matching.
+
+![](oh-my-glob.gif)
+
+## Usage
+
+Install with npm
+
+```
+npm i glob
+```
+
+```javascript
+var glob = require("glob")
+
+// options is optional
+glob("**/*.js", options, function (er, files) {
+  // files is an array of filenames.
+  // If the `nonull` option is set, and nothing
+  // was found, then files is ["**/*.js"]
+  // er is an error object or null.
+})
+```
+
+## Glob Primer
+
+"Globs" are the patterns you type when you do stuff like `ls *.js` on
+the command line, or put `build/*` in a `.gitignore` file.
+
+Before parsing the path part patterns, braced sections are expanded
+into a set.  Braced sections start with `{` and end with `}`, with any
+number of comma-delimited sections within.  Braced sections may contain
+slash characters, so `a{/b/c,bcd}` would expand into `a/b/c` and `abcd`.
+
+The following characters have special magic meaning when used in a
+path portion:
+
+* `*` Matches 0 or more characters in a single path portion
+* `?` Matches 1 character
+* `[...]` Matches a range of characters, similar to a RegExp range.
+  If the first character of the range is `!` or `^` then it matches
+  any character not in the range.
+* `!(pattern|pattern|pattern)` Matches anything that does not match
+  any of the patterns provided.
+* `?(pattern|pattern|pattern)` Matches zero or one occurrence of the
+  patterns provided.
+* `+(pattern|pattern|pattern)` Matches one or more occurrences of the
+  patterns provided.
+* `*(a|b|c)` Matches zero or more occurrences of the patterns provided
+* `@(pattern|pat*|pat?erN)` Matches exactly one of the patterns
+  provided
+* `**` If a "globstar" is alone in a path portion, then it matches
+  zero or more directories and subdirectories searching for matches.
+  It does not crawl symlinked directories.
+
+### Dots
+
+If a file or directory path portion has a `.` as the first character,
+then it will not match any glob pattern unless that pattern's
+corresponding path part also has a `.` as its first character.
+
+For example, the pattern `a/.*/c` would match the file at `a/.b/c`.
+However the pattern `a/*/c` would not, because `*` does not start with
+a dot character.
+
+You can make glob treat dots as normal characters by setting
+`dot:true` in the options.
+
+### Basename Matching
+
+If you set `matchBase:true` in the options, and the pattern has no
+slashes in it, then it will seek for any file anywhere in the tree
+with a matching basename.  For example, `*.js` would match
+`test/simple/basic.js`.
+
+### Empty Sets
+
+If no matching files are found, then an empty array is returned.  This
+differs from the shell, where the pattern itself is returned.  For
+example:
+
+    $ echo a*s*d*f
+    a*s*d*f
+
+To get the bash-style behavior, set the `nonull:true` in the options.
+
+### See Also:
+
+* `man sh`
+* `man bash` (Search for "Pattern Matching")
+* `man 3 fnmatch`
+* `man 5 gitignore`
+* [minimatch documentation](https://github.com/isaacs/minimatch)
+
+## glob.hasMagic(pattern, [options])
+
+Returns `true` if there are any special characters in the pattern, and
+`false` otherwise.
+
+Note that the options affect the results.  If `noext:true` is set in
+the options object, then `+(a|b)` will not be considered a magic
+pattern.  If the pattern has a brace expansion, like `a/{b/c,x/y}`
+then that is considered magical, unless `nobrace:true` is set in the
+options.
+
+## glob(pattern, [options], cb)
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* `cb` `{Function}`
+  * `err` `{Error | null}`
+  * `matches` `{Array<String>}` filenames found matching the pattern
+
+Perform an asynchronous glob search.
+
+## glob.sync(pattern, [options])
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* return: `{Array<String>}` filenames found matching the pattern
+
+Perform a synchronous glob search.
+
+## Class: glob.Glob
+
+Create a Glob object by instantiating the `glob.Glob` class.
+
+```javascript
+var Glob = require("glob").Glob
+var mg = new Glob(pattern, options, cb)
+```
+
+It's an EventEmitter, and starts walking the filesystem to find matches
+immediately.
+
+### new glob.Glob(pattern, [options], [cb])
+
+* `pattern` `{String}` pattern to search for
+* `options` `{Object}`
+* `cb` `{Function}` Called when an error occurs, or matches are found
+  * `err` `{Error | null}`
+  * `matches` `{Array<String>}` filenames found matching the pattern
+
+Note that if the `sync` flag is set in the options, then matches will
+be immediately available on the `g.found` member.
+
+### Properties
+
+* `minimatch` The minimatch object that the glob uses.
+* `options` The options object passed in.
+* `aborted` Boolean which is set to true when calling `abort()`.  There
+  is no way at this time to continue a glob search after aborting, but
+  you can re-use the statCache to avoid having to duplicate syscalls.
+* `cache` Convenience object.  Each field has the following possible
+  values:
+  * `false` - Path does not exist
+  * `true` - Path exists
+  * `'FILE'` - Path exists, and is not a directory
+  * `'DIR'` - Path exists, and is a directory
+  * `[file, entries, ...]` - Path exists, is a directory, and the
+    array value is the results of `fs.readdir`
+* `statCache` Cache of `fs.stat` results, to prevent statting the same
+  path multiple times.
+* `symlinks` A record of which paths are symbolic links, which is
+  relevant in resolving `**` patterns.
+* `realpathCache` An optional object which is passed to `fs.realpath`
+  to minimize unnecessary syscalls.  It is stored on the instantiated
+  Glob object, and may be re-used.
+
+### Events
+
+* `end` When the matching is finished, this is emitted with all the
+  matches found.  If the `nonull` option is set, and no match was found,
+  then the `matches` list contains the original pattern.  The matches
+  are sorted, unless the `nosort` flag is set.
+* `match` Every time a match is found, this is emitted with the specific
+  thing that matched. It is not deduplicated or resolved to a realpath.
+* `error` Emitted when an unexpected error is encountered, or whenever
+  any fs error occurs if `options.strict` is set.
+* `abort` When `abort()` is called, this event is raised.
+
+### Methods
+
+* `pause` Temporarily stop the search
+* `resume` Resume the search
+* `abort` Stop the search forever
+
+### Options
+
+All the options that can be passed to Minimatch can also be passed to
+Glob to change pattern matching behavior.  Also, some have been added,
+or have glob-specific ramifications.
+
+All options are false by default, unless otherwise noted.
+
+All options are added to the Glob object, as well.
+
+If you are running many `glob` operations, you can pass a Glob object
+as the `options` argument to a subsequent operation to shortcut some
+`stat` and `readdir` calls.  At the very least, you may pass in shared
+`symlinks`, `statCache`, `realpathCache`, and `cache` options, so that
+parallel glob operations will be sped up by sharing information about
+the filesystem.
+
+* `cwd` The current working directory in which to search.  Defaults
+  to `process.cwd()`.
+* `root` The place where patterns starting with `/` will be mounted
+  onto.  Defaults to `path.resolve(options.cwd, "/")` (`/` on Unix
+  systems, and `C:\` or some such on Windows.)
+* `dot` Include `.dot` files in normal matches and `globstar` matches.
+  Note that an explicit dot in a portion of the pattern will always
+  match dot files.
+* `nomount` By default, a pattern starting with a forward-slash will be
+  "mounted" onto the root setting, so that a valid filesystem path is
+  returned.  Set this flag to disable that behavior.
+* `mark` Add a `/` character to directory matches.  Note that this
+  requires additional stat calls.
+* `nosort` Don't sort the results.
+* `stat` Set to true to stat *all* results.  This reduces performance
+  somewhat, and is completely unnecessary, unless `readdir` is presumed
+  to be an untrustworthy indicator of file existence.
+* `silent` When an unusual error is encountered when attempting to
+  read a directory, a warning will be printed to stderr.  Set the
+  `silent` option to true to suppress these warnings.
+* `strict` When an unusual error is encountered when attempting to
+  read a directory, the process will just continue on in search of
+  other matches.  Set the `strict` option to raise an error in these
+  cases.
+* `cache` See `cache` property above.  Pass in a previously generated
+  cache object to save some fs calls.
+* `statCache` A cache of results of filesystem information, to prevent
+  unnecessary stat calls.  While it should not normally be necessary
+  to set this, you may pass the statCache from one glob() call to the
+  options object of another, if you know that the filesystem will not
+  change between calls.  (See "Race Conditions" below.)
+* `symlinks` A cache of known symbolic links.  You may pass in a
+  previously generated `symlinks` object to save `lstat` calls when
+  resolving `**` matches.
+* `sync` DEPRECATED: use `glob.sync(pattern, opts)` instead.
+* `nounique` In some cases, brace-expanded patterns can result in the
+  same file showing up multiple times in the result set.  By default,
+  this implementation prevents duplicates in the result set.  Set this
+  flag to disable that behavior.
+* `nonull` Set to never return an empty set, instead returning a set
+  containing the pattern itself.  This is the default in glob(3).
+* `debug` Set to enable debug logging in minimatch and glob.
+* `nobrace` Do not expand `{a,b}` and `{1..3}` brace sets.
+* `noglobstar` Do not match `**` against multiple filenames.  (Ie,
+  treat it as a normal `*` instead.)
+* `noext` Do not match `+(a|b)` "extglob" patterns.
+* `nocase` Perform a case-insensitive match.  Note: on
+  case-insensitive filesystems, non-magic patterns will match by
+  default, since `stat` and `readdir` will not raise errors.
+* `matchBase` Perform a basename-only match if the pattern does not
+  contain any slash characters.  That is, `*.js` would be treated as
+  equivalent to `**/*.js`, matching all js files in all directories.
+* `nodir` Do not match directories, only files.  (Note: to match
+  *only* directories, simply put a `/` at the end of the pattern.)
+* `ignore` Add a pattern or an array of glob patterns to exclude matches.
+  Note: `ignore` patterns are *always* in `dot:true` mode, regardless
+  of any other settings.
+* `follow` Follow symlinked directories when expanding `**` patterns.
+  Note that this can result in a lot of duplicate references in the
+  presence of cyclic links.
+* `realpath` Set to true to call `fs.realpath` on all of the results.
+  In the case of a symlink that cannot be resolved, the full absolute
+  path to the matched entry is returned (though it will usually be a
+  broken symlink)
+* `absolute` Set to true to always receive absolute paths for matched
+  files.  Unlike `realpath`, this also affects the values returned in
+  the `match` event.
+
+## Comparisons to other fnmatch/glob implementations
+
+While strict compliance with the existing standards is a worthwhile
+goal, some discrepancies exist between node-glob and other
+implementations, and are intentional.
+
+The double-star character `**` is supported by default, unless the
+`noglobstar` flag is set.  This is supported in the manner of bsdglob
+and bash 4.3, where `**` only has special significance if it is the only
+thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
+`a/**b` will not.
+
+Note that symlinked directories are not crawled as part of a `**`,
+though their contents may match against subsequent portions of the
+pattern.  This prevents infinite loops and duplicates and the like.
+
+If an escaped pattern has no matches, and the `nonull` flag is set,
+then glob returns the pattern as-provided, rather than
+interpreting the character escapes.  For example,
+`glob.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
+`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
+that it does not resolve escaped pattern characters.
+
+If brace expansion is not disabled, then it is performed before any
+other interpretation of the glob pattern.  Thus, a pattern like
+`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
+**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
+checked for validity.  Since those two are valid, matching proceeds.
+
+### Comments and Negation
+
+Previously, this module let you mark a pattern as a "comment" if it
+started with a `#` character, or a "negated" pattern if it started
+with a `!` character.
+
+These options were deprecated in version 5, and removed in version 6.
+
+To specify things that should not match, use the `ignore` option.
+
+## Windows
+
+**Please only use forward-slashes in glob expressions.**
+
+Though windows uses either `/` or `\` as its path separator, only `/`
+characters are used by this glob implementation.  You must use
+forward-slashes **only** in glob expressions.  Back-slashes will always
+be interpreted as escape characters, not path separators.
+
+Results from absolute patterns such as `/foo/*` are mounted onto the
+root setting using `path.join`.  On windows, this will by default result
+in `/foo/*` matching `C:\foo\bar.txt`.
+
+## Race Conditions
+
+Glob searching, by its very nature, is susceptible to race conditions,
+since it relies on directory walking and such.
+
+As a result, it is possible that a file that exists when glob looks for
+it may have been deleted or modified by the time it returns the result.
+
+As part of its internal implementation, this program caches all stat
+and readdir calls that it makes, in order to cut down on system
+overhead.  However, this also makes it even more susceptible to races,
+especially if the cache or statCache objects are reused between glob
+calls.
+
+Users are thus advised not to use a glob result as a guarantee of
+filesystem state in the face of rapid changes.  For the vast majority
+of operations, this is never a problem.
+
+## Contributing
+
+Any change to behavior (including bugfixes) must come with a test.
+
+Patches that fail tests or reduce performance will be rejected.

+## 7.0
+
+- Raise error if `options.cwd` is specified, and not a directory
+
+## 6.0
+
+- Remove comment and negation pattern support
+- Ignore patterns are always in `dot:true` mode
+
+## 5.0
+
+- Deprecate comment and negation patterns
+- Fix regression in `mark` and `nodir` options from making all cache
+  keys absolute path.
+- Abort if `fs.readdir` returns an error that's unexpected
+- Don't emit `match` events for ignored items
+- Treat ENOTSUP like ENOTDIR in readdir
+
+## 4.5
+
+- Add `options.follow` to always follow directory symlinks in globstar
+- Add `options.realpath` to call `fs.realpath` on all results
+- Always cache based on absolute path
+
+## 4.4
+
+- Add `options.ignore`
+- Fix handling of broken symlinks
+
+## 4.3
+
+- Bump minimatch to 2.x
+- Pass all tests on Windows
+
+## 4.2
+
+- Add `glob.hasMagic` function
+- Add `options.nodir` flag
+
+## 4.1
+
+- Refactor sync and async implementations for performance
+- Throw if callback provided to sync glob function
+- Treat symbolic links in globstar results the same as Bash 4.3
+
+## 4.0
+
+- Use `^` for dependency versions (bumped major because this breaks
+  older npm versions)
+- Ensure callbacks are only ever called once
+- switch to ISC license
+
+## 3.x
+
+- Rewrite in JavaScript
+- Add support for setting root, cwd, and windows support
+- Cache many fs calls

+# globals [![Build Status](https://travis-ci.org/sindresorhus/globals.svg?branch=master)](https://travis-ci.org/sindresorhus/globals)
+
+> Global identifiers from different JavaScript environments
+
+Extracted from [JSHint](https://github.com/jshint/jshint/blob/3a8efa979dbb157bfb5c10b5826603a55a33b9ad/src/vars.js) and [ESLint](https://github.com/eslint/eslint/blob/b648406218f8a2d7302b98f5565e23199f44eb31/conf/environments.json) and merged.
+
+It's just a [JSON file](globals.json), so use it in whatever environment you like.
+
+**This module [no longer accepts](https://github.com/sindresorhus/globals/issues/82) new environments. If you need it for ESLint, just [create a plugin](http://eslint.org/docs/developer-guide/working-with-plugins#environments-in-plugins).**
+
+
+## Install
+
+```
+$ npm install globals
+```
+
+
+## Usage
+
+```js
+const globals = require('globals');
+
+console.log(globals.browser);
+/*
+{
+	addEventListener: false,
+	applicationCache: false,
+	ArrayBuffer: false,
+	atob: false,
+	...
+}
+*/
+```
+
+Each global is given a value of `true` or `false`. A value of `true` indicates that the variable may be overwritten. A value of `false` indicates that the variable should be considered read-only. This information is used by static analysis tools to flag incorrect behavior. We assume all variables should be `false` unless we hear otherwise.

+# globby [![Build Status](https://travis-ci.org/sindresorhus/globby.svg?branch=master)](https://travis-ci.org/sindresorhus/globby)
+
+> Extends [glob](https://github.com/isaacs/node-glob) with support for multiple patterns and exposes a Promise API
+
+
+## Install
+
+```
+$ npm install --save globby
+```
+
+
+## Usage
+
+```
+├── unicorn
+├── cake
+└── rainbow
+```
+
+```js
+const globby = require('globby');
+
+globby(['*', '!cake']).then(paths => {
+	console.log(paths);
+	//=> ['unicorn', 'rainbow']
+});
+```
+
+
+## API
+
+### globby(patterns, [options])
+
+Returns a Promise for an array of matching paths.
+
+### globby.sync(patterns, [options])
+
+Returns an array of matching paths.
+
+### globby.generateGlobTasks(patterns, [options])
+
+Returns an array of objects in the format `{ pattern: string, opts: Object }`, which can be passed as arguments to [`node-glob`](https://github.com/isaacs/node-glob). This is useful for other globbing-related packages.
+
+Note that you should avoid running the same tasks multiple times as they contain a file system cache. Instead, create a new tasks list to ensure that file system changes are taken in consideration.
+
+#### patterns
+
+Type: `string`, `Array`
+
+See supported `minimatch` [patterns](https://github.com/isaacs/minimatch#usage).
+
+#### options
+
+Type: `Object`
+
+See the `node-glob` [options](https://github.com/isaacs/node-glob#options).
+
+
+## Globbing patterns
+
+Just a quick overview.
+
+- `*` matches any number of characters, but not `/`
+- `?` matches a single character, but not `/`
+- `**` matches any number of characters, including `/`, as long as it's the only thing in a path part
+- `{}` allows for a comma-separated list of "or" expressions
+- `!` at the beginning of a pattern will negate the match
+
+[Various patterns and expected matches.](https://github.com/sindresorhus/multimatch/blob/master/test.js)
+
+
+## Related
+
+- [multimatch](https://github.com/sindresorhus/multimatch) - Match against a list instead of the filesystem
+- [glob-stream](https://github.com/wearefractal/glob-stream) - Streaming alternative
+- [matcher](https://github.com/sindresorhus/matcher) - Simple wildcard matching

+# graceful-fs
+
+graceful-fs functions as a drop-in replacement for the fs module,
+making various improvements.
+
+The improvements are meant to normalize behavior across different
+platforms and environments, and to make filesystem access more
+resilient to errors.
+
+## Improvements over [fs module](https://nodejs.org/api/fs.html)
+
+* Queues up `open` and `readdir` calls, and retries them once
+  something closes if there is an EMFILE error from too many file
+  descriptors.
+* fixes `lchmod` for Node versions prior to 0.6.2.
+* implements `fs.lutimes` if possible. Otherwise it becomes a noop.
+* ignores `EINVAL` and `EPERM` errors in `chown`, `fchown` or
+  `lchown` if the user isn't root.
+* makes `lchmod` and `lchown` become noops, if not available.
+* retries reading a file if `read` results in EAGAIN error.
+
+On Windows, it retries renaming a file for up to one second if `EACCESS`
+or `EPERM` error occurs, likely because antivirus software has locked
+the directory.
+
+## USAGE
+
+```javascript
+// use just like fs
+var fs = require('graceful-fs')
+
+// now go and do stuff with it...
+fs.readFileSync('some-file-or-whatever')
+```
+
+## Global Patching
+
+If you want to patch the global fs module (or any other fs-like
+module) you can do this:
+
+```javascript
+// Make sure to read the caveat below.
+var realFs = require('fs')
+var gracefulFs = require('graceful-fs')
+gracefulFs.gracefulify(realFs)
+```
+
+This should only ever be done at the top-level application layer, in
+order to delay on EMFILE errors from any fs-using dependencies.  You
+should **not** do this in a library, because it can cause unexpected
+delays in other parts of the program.
+
+## Changes
+
+This module is fairly stable at this point, and used by a lot of
+things.  That being said, because it implements a subtle behavior
+change in a core part of the node API, even modest changes can be
+extremely breaking, and the versioning is thus biased towards
+bumping the major when in doubt.
+
+The main change between major versions has been switching between
+providing a fully-patched `fs` module vs monkey-patching the node core
+builtin, and the approach by which a non-monkey-patched `fs` was
+created.
+
+The goal is to trade `EMFILE` errors for slower fs operations.  So, if
+you try to open a zillion files, rather than crashing, `open`
+operations will be queued up and wait for something else to `close`.
+
+There are advantages to each approach.  Monkey-patching the fs means
+that no `EMFILE` errors can possibly occur anywhere in your
+application, because everything is using the same core `fs` module,
+which is patched.  However, it can also obviously cause undesirable
+side-effects, especially if the module is loaded multiple times.
+
+Implementing a separate-but-identical patched `fs` module is more
+surgical (and doesn't run the risk of patching multiple times), but
+also imposes the challenge of keeping in sync with the core module.
+
+The current approach loads the `fs` module, and then creates a
+lookalike object that has all the same methods, except a few that are
+patched.  It is safe to use in all versions of Node from 0.8 through
+7.0.
+
+### v4
+
+* Do not monkey-patch the fs module.  This module may now be used as a
+  drop-in dep, and users can opt into monkey-patching the fs builtin
+  if their app requires it.
+
+### v3
+
+* Monkey-patch fs, because the eval approach no longer works on recent
+  node.
+* fixed possible type-error throw if rename fails on windows
+* verify that we *never* get EMFILE errors
+* Ignore ENOSYS from chmod/chown
+* clarify that graceful-fs must be used as a drop-in
+
+### v2.1.0
+
+* Use eval rather than monkey-patching fs.
+* readdir: Always sort the results
+* win32: requeue a file if error has an OK status
+
+### v2.0
+
+* A return to monkey patching
+* wrap process.cwd
+
+### v1.1
+
+* wrap readFile
+* Wrap fs.writeFile.
+* readdir protection
+* Don't clobber the fs builtin
+* Handle fs.read EAGAIN errors by trying again
+* Expose the curOpen counter
+* No-op lchown/lchmod if not implemented
+* fs.rename patch only for win32
+* Patch fs.rename to handle AV software on Windows
+* Close #4 Chown should not fail on einval or eperm if non-root
+* Fix isaacs/fstream#1 Only wrap fs one time
+* Fix #3 Start at 1024 max files, then back off on EMFILE
+* lutimes that doens't blow up on Linux
+* A full on-rewrite using a queue instead of just swallowing the EMFILE error
+* Wrap Read/Write streams as well
+
+### 1.0
+
+* Update engines for node 0.6
+* Be lstat-graceful on Windows
+* first

+## Pure JS character encoding conversion [![Build Status](https://travis-ci.org/ashtuchkin/iconv-lite.svg?branch=master)](https://travis-ci.org/ashtuchkin/iconv-lite)
+
+ * Doesn't need native code compilation. Works on Windows and in sandboxed environments like [Cloud9](http://c9.io).
+ * Used in popular projects like [Express.js (body_parser)](https://github.com/expressjs/body-parser), 
+   [Grunt](http://gruntjs.com/), [Nodemailer](http://www.nodemailer.com/), [Yeoman](http://yeoman.io/) and others.
+ * Faster than [node-iconv](https://github.com/bnoordhuis/node-iconv) (see below for performance comparison).
+ * Intuitive encode/decode API
+ * Streaming support for Node v0.10+
+ * [Deprecated] Can extend Node.js primitives (buffers, streams) to support all iconv-lite encodings.
+ * In-browser usage via [Browserify](https://github.com/substack/node-browserify) (~180k gzip compressed with Buffer shim included).
+ * Typescript [type definition file](https://github.com/ashtuchkin/iconv-lite/blob/master/lib/index.d.ts) included.
+ * React Native is supported (need to explicitly `npm install` two more modules: `buffer` and `stream`).
+ * License: MIT.
+
+[![NPM Stats](https://nodei.co/npm/iconv-lite.png?downloads=true&downloadRank=true)](https://npmjs.org/packages/iconv-lite/)
+
+## Usage
+### Basic API
+```javascript
+var iconv = require('iconv-lite');
+
+// Convert from an encoded buffer to js string.
+str = iconv.decode(new Buffer([0x68, 0x65, 0x6c, 0x6c, 0x6f]), 'win1251');
+
+// Convert from js string to an encoded buffer.
+buf = iconv.encode("Sample input string", 'win1251');
+
+// Check if encoding is supported
+iconv.encodingExists("us-ascii")
+```
+
+### Streaming API (Node v0.10+)
+```javascript
+
+// Decode stream (from binary stream to js strings)
+http.createServer(function(req, res) {
+    var converterStream = iconv.decodeStream('win1251');
+    req.pipe(converterStream);
+
+    converterStream.on('data', function(str) {
+        console.log(str); // Do something with decoded strings, chunk-by-chunk.
+    });
+});
+
+// Convert encoding streaming example
+fs.createReadStream('file-in-win1251.txt')
+    .pipe(iconv.decodeStream('win1251'))
+    .pipe(iconv.encodeStream('ucs2'))
+    .pipe(fs.createWriteStream('file-in-ucs2.txt'));
+
+// Sugar: all encode/decode streams have .collect(cb) method to accumulate data.
+http.createServer(function(req, res) {
+    req.pipe(iconv.decodeStream('win1251')).collect(function(err, body) {
+        assert(typeof body == 'string');
+        console.log(body); // full request body string
+    });
+});
+```
+
+### [Deprecated] Extend Node.js own encodings
+> NOTE: This doesn't work on latest Node versions. See [details](https://github.com/ashtuchkin/iconv-lite/wiki/Node-v4-compatibility).
+
+```javascript
+// After this call all Node basic primitives will understand iconv-lite encodings.
+iconv.extendNodeEncodings();
+
+// Examples:
+buf = new Buffer(str, 'win1251');
+buf.write(str, 'gbk');
+str = buf.toString('latin1');
+assert(Buffer.isEncoding('iso-8859-15'));
+Buffer.byteLength(str, 'us-ascii');
+
+http.createServer(function(req, res) {
+    req.setEncoding('big5');
+    req.collect(function(err, body) {
+        console.log(body);
+    });
+});
+
+fs.createReadStream("file.txt", "shift_jis");
+
+// External modules are also supported (if they use Node primitives, which they probably do).
+request = require('request');
+request({
+    url: "http://github.com/", 
+    encoding: "cp932"
+});
+
+// To remove extensions
+iconv.undoExtendNodeEncodings();
+```
+
+## Supported encodings
+
+ *  All node.js native encodings: utf8, ucs2 / utf16-le, ascii, binary, base64, hex.
+ *  Additional unicode encodings: utf16, utf16-be, utf-7, utf-7-imap.
+ *  All widespread singlebyte encodings: Windows 125x family, ISO-8859 family, 
+    IBM/DOS codepages, Macintosh family, KOI8 family, all others supported by iconv library. 
+    Aliases like 'latin1', 'us-ascii' also supported.
+ *  All widespread multibyte encodings: CP932, CP936, CP949, CP950, GB2312, GBK, GB18030, Big5, Shift_JIS, EUC-JP.
+
+See [all supported encodings on wiki](https://github.com/ashtuchkin/iconv-lite/wiki/Supported-Encodings).
+
+Most singlebyte encodings are generated automatically from [node-iconv](https://github.com/bnoordhuis/node-iconv). Thank you Ben Noordhuis and libiconv authors!
+
+Multibyte encodings are generated from [Unicode.org mappings](http://www.unicode.org/Public/MAPPINGS/) and [WHATWG Encoding Standard mappings](http://encoding.spec.whatwg.org/). Thank you, respective authors!
+
+
+## Encoding/decoding speed
+
+Comparison with node-iconv module (1000x256kb, on MacBook Pro, Core i5/2.6 GHz, Node v0.12.0). 
+Note: your results may vary, so please always check on your hardware.
+
+    operation             iconv@2.1.4   iconv-lite@0.4.7
+    ----------------------------------------------------------
+    encode('win1251')     ~96 Mb/s      ~320 Mb/s
+    decode('win1251')     ~95 Mb/s      ~246 Mb/s
+
+## BOM handling
+
+ * Decoding: BOM is stripped by default, unless overridden by passing `stripBOM: false` in options
+   (f.ex. `iconv.decode(buf, enc, {stripBOM: false})`).
+   A callback might also be given as a `stripBOM` parameter - it'll be called if BOM character was actually found.
+ * If you want to detect UTF-8 BOM when decoding other encodings, use [node-autodetect-decoder-stream](https://github.com/danielgindi/node-autodetect-decoder-stream) module.
+ * Encoding: No BOM added, unless overridden by `addBOM: true` option.
+
+## UTF-16 Encodings
+
+This library supports UTF-16LE, UTF-16BE and UTF-16 encodings. First two are straightforward, but UTF-16 is trying to be
+smart about endianness in the following ways:
+ * Decoding: uses BOM and 'spaces heuristic' to determine input endianness. Default is UTF-16LE, but can be 
+   overridden with `defaultEncoding: 'utf-16be'` option. Strips BOM unless `stripBOM: false`.
+ * Encoding: uses UTF-16LE and writes BOM by default. Use `addBOM: false` to override.
+
+## Other notes
+
+When decoding, be sure to supply a Buffer to decode() method, otherwise [bad things usually happen](https://github.com/ashtuchkin/iconv-lite/wiki/Use-Buffers-when-decoding).  
+Untranslatable characters are set to � or ?. No transliteration is currently supported.  
+Node versions 0.10.31 and 0.11.13 are buggy, don't use them (see #65, #77).  
+
+## Testing
+
+```bash
+$ git clone git@github.com:ashtuchkin/iconv-lite.git
+$ cd iconv-lite
+$ npm install
+$ npm test
+    
+$ # To view performance:
+$ node test/performance.js
+
+$ # To view test coverage:
+$ npm run coverage
+$ open coverage/lcov-report/index.html

+    // All japanese encodings are based on JIS X set of standards:
+    // JIS X 0201 - Single-byte encoding of ASCII + ¥ + Kana chars at 0xA1-0xDF.
+    // JIS X 0208 - Main set of 6879 characters, placed in 94x94 plane, to be encoded by 2 bytes. 
+    //              Has several variations in 1978, 1983, 1990 and 1997.
+    // JIS X 0212 - Supplementary plane of 6067 chars in 94x94 plane. 1990. Effectively dead.
+    // JIS X 0213 - Extension and modern replacement of 0208 and 0212. Total chars: 11233.
+    //              2 planes, first is superset of 0208, second - revised 0212.
+    //              Introduced in 2000, revised 2004. Some characters are in Unicode Plane 2 (0x2xxxx)
+
+    // Byte encodings are:
+    //  * Shift_JIS: Compatible with 0201, uses not defined chars in top half as lead bytes for double-byte
+    //               encoding of 0208. Lead byte ranges: 0x81-0x9F, 0xE0-0xEF; Trail byte ranges: 0x40-0x7E, 0x80-0x9E, 0x9F-0xFC.
+    //               Windows CP932 is a superset of Shift_JIS. Some companies added more chars, notably KDDI.
+    //  * EUC-JP:    Up to 3 bytes per character. Used mostly on *nixes.
+    //               0x00-0x7F       - lower part of 0201
+    //               0x8E, 0xA1-0xDF - upper part of 0201
+    //               (0xA1-0xFE)x2   - 0208 plane (94x94).
+    //               0x8F, (0xA1-0xFE)x2 - 0212 plane (94x94).
+    //  * JIS X 208: 7-bit, direct encoding of 0208. Byte ranges: 0x21-0x7E (94 values). Uncommon.
+    //               Used as-is in ISO2022 family.
+    //  * ISO2022-JP: Stateful encoding, with escape sequences to switch between ASCII, 
+    //                0201-1976 Roman, 0208-1978, 0208-1983.
+    //  * ISO2022-JP-1: Adds esc seq for 0212-1990.
+    //  * ISO2022-JP-2: Adds esc seq for GB2313-1980, KSX1001-1992, ISO8859-1, ISO8859-7.
+    //  * ISO2022-JP-3: Adds esc seq for 0201-1976 Kana set, 0213-2000 Planes 1, 2.
+    //  * ISO2022-JP-2004: Adds 0213-2004 Plane 1.
+    //
+    // After JIS X 0213 appeared, Shift_JIS-2004, EUC-JISX0213 and ISO2022-JP-2004 followed, with just changing the planes.

+
+# ignore
+
+`ignore` is a manager, filter and parser which implemented in pure JavaScript according to the .gitignore [spec](http://git-scm.com/docs/gitignore).
+
+Pay attention that [`minimatch`](https://www.npmjs.org/package/minimatch) does not work in the gitignore way. To filter filenames according to .gitignore file, I recommend this module.
+
+##### Tested on
+
+- Linux + Node: `0.8` - `7.x`
+- Windows + Node: `0.10` - `7.x`, node < `0.10` is not tested due to the lack of support of appveyor.
+
+Actually, `ignore` does not rely on any versions of node specially.
+
+## Table Of Main Contents
+
+- [Usage](#usage)
+- [Guide for 2.x -> 3.x](#upgrade-2x---3x)
+- [Contributing](#contributing)
+- Related Packages
+  - [`glob-gitignore`](https://www.npmjs.com/package/glob-gitignore) matches files using patterns and filters them according to gitignore rules.
+
+## Usage
+
+```js
+const ignore = require('ignore')
+const ig = ignore().add(['.abc/*', '!.abc/d/'])
+```
+
+### Filter the given paths
+
+```js
+const paths = [
+  '.abc/a.js',    // filtered out
+  '.abc/d/e.js'   // included
+]
+
+ig.filter(paths)        // ['.abc/d/e.js']
+ig.ignores('.abc/a.js') // true
+```
+
+### As the filter function
+
+```js
+paths.filter(ig.createFilter()); // ['.abc/d/e.js']
+```
+
+### Win32 paths will be handled
+
+```js
+ig.filter(['.abc\\a.js', '.abc\\d\\e.js'])
+// if the code above runs on windows, the result will be
+// ['.abc\\d\\e.js']
+```
+
+## Why another ignore?
+
+- `ignore` is a standalone module, and is much simpler so that it could easy work with other programs, unlike [isaacs](https://npmjs.org/~isaacs)'s [fstream-ignore](https://npmjs.org/package/fstream-ignore) which must work with the modules of the fstream family.
+
+- `ignore` only contains utility methods to filter paths according to the specified ignore rules, so
+  - `ignore` never try to find out ignore rules by traversing directories or fetching from git configurations.
+  - `ignore` don't cares about sub-modules of git projects.
+
+- Exactly according to [gitignore man page](http://git-scm.com/docs/gitignore), fixes some known matching issues of fstream-ignore, such as:
+  - '`/*.js`' should only match '`a.js`', but not '`abc/a.js`'.
+  - '`**/foo`' should match '`foo`' anywhere.
+  - Prevent re-including a file if a parent directory of that file is excluded.
+  - Handle trailing whitespaces:
+    - `'a '`(one space) should not match `'a  '`(two spaces).
+    - `'a \ '` matches `'a  '`
+  - All test cases are verified with the result of `git check-ignore`.
+
+## Methods
+
+### .add(pattern)
+### .add(patterns)
+
+- **pattern** `String|Ignore` An ignore pattern string, or the `Ignore` instance
+- **patterns** `Array.<pattern>` Array of ignore patterns.
+
+Adds a rule or several rules to the current manager.
+
+Returns `this`
+
+Notice that a line starting with `'#'`(hash) is treated as a comment. Put a backslash (`'\'`) in front of the first hash for patterns that begin with a hash, if you want to ignore a file with a hash at the beginning of the filename.
+
+```js
+ignore().add('#abc').ignores('#abc')    // false
+ignore().add('\#abc').ignores('#abc')   // true
+```
+
+`pattern` could either be a line of ignore pattern or a string of multiple ignore patterns, which means we could just `ignore().add()` the content of a ignore file:
+
+```js
+ignore()
+.add(fs.readFileSync(filenameOfGitignore).toString())
+.filter(filenames)
+```
+
+`pattern` could also be an `ignore` instance, so that we could easily inherit the rules of another `Ignore` instance.
+
+### <strike>.addIgnoreFile(path)</strike>
+
+REMOVED in `3.x` for now.
+
+To upgrade `ignore@2.x` up to `3.x`, use
+
+```js
+const fs = require('fs')
+
+if (fs.existsSync(filename)) {
+  ignore().add(fs.readFileSync(filename).toString())
+}
+```
+
+instead.
+
+
+### .ignores(pathname)
+
+> new in 3.2.0
+
+Returns `Boolean` whether `pathname` should be ignored.
+
+```js
+ig.ignores('.abc/a.js')    // true
+```
+
+### .filter(paths)
+
+Filters the given array of pathnames, and returns the filtered array.
+
+- **paths** `Array.<path>` The array of `pathname`s to be filtered.
+
+**NOTICE** that:
+
+- `pathname` should be a string that have been `path.join()`ed, or the return value of `path.relative()` to the current directory.
+
+```js
+// WRONG
+ig.ignores('./abc')
+
+// WRONG, for it will never happen.
+// If the gitignore rule locates at the root directory,
+// `'/abc'` should be changed to `'abc'`.
+// ```
+// path.relative('/', '/abc')  -> 'abc'
+// ```
+ig.ignores('/abc')
+
+// Right
+ig.ignores('abc')
+
+// Right
+ig.ignores(path.join('./abc'))  // path.join('./abc') -> 'abc'
+```
+
+- In other words, each `pathname` here should be a relative path to the directory of the git ignore rules.
+
+Suppose the dir structure is:
+
+```
+/path/to/your/repo
+    |-- a
+    |   |-- a.js
+    |
+    |-- .b
+    |
+    |-- .c
+         |-- .DS_store
+```
+
+Then the `paths` might be like this:
+
+```js
+[
+  'a/a.js'
+  '.b',
+  '.c/.DS_store'
+]
+```
+
+Usually, you could use [`glob`](http://npmjs.org/package/glob) with `option.mark = true` to fetch the structure of the current directory:
+
+```js
+const glob = require('glob')
+
+glob('**', {
+  // Adds a / character to directory matches.
+  mark: true
+}, (err, files) => {
+  if (err) {
+    return console.error(err)
+  }
+
+  let filtered = ignore().add(patterns).filter(files)
+  console.log(filtered)
+})
+```
+
+### .createFilter()
+
+Creates a filter function which could filter an array of paths with `Array.prototype.filter`.
+
+Returns `function(path)` the filter function.
+
+****
+
+## Upgrade 2.x -> 3.x
+
+- All `options` of 2.x are unnecessary and removed, so just remove them.
+- `ignore()` instance is no longer an [`EventEmitter`](nodejs.org/api/events.html), and all events are unnecessary and removed.
+- `.addIgnoreFile()` is removed, see the [.addIgnoreFile](#addignorefilepath) section for details.
+
+****
+
+## Contributing
+
+The code of `node-ignore` is based on es6 and babel, but babel and its preset is not included in the `dependencies` field of package.json, so that the installation process of test cases will not fail in older versions of node.
+
+So use `bash install.sh` to install dependencies and `bash test.sh` to run test cases in your local machine.

+iMurmurHash.js
+==============
+
+An incremental implementation of the MurmurHash3 (32-bit) hashing algorithm for JavaScript based on [Gary Court's implementation](https://github.com/garycourt/murmurhash-js) with [kazuyukitanimura's modifications](https://github.com/kazuyukitanimura/murmurhash-js).
+
+This version works significantly faster than the non-incremental version if you need to hash many small strings into a single hash, since string concatenation (to build the single string to pass the non-incremental version) is fairly costly. In one case tested, using the incremental version was about 50% faster than concatenating 5-10 strings and then hashing.
+
+Installation
+------------
+
+To use iMurmurHash in the browser, [download the latest version](https://raw.github.com/jensyt/imurmurhash-js/master/imurmurhash.min.js) and include it as a script on your site.
+
+```html
+<script type="text/javascript" src="/scripts/imurmurhash.min.js"></script>
+<script>
+// Your code here, access iMurmurHash using the global object MurmurHash3
+</script>
+```
+
+---
+
+To use iMurmurHash in Node.js, install the module using NPM:
+
+```bash
+npm install imurmurhash
+```
+
+Then simply include it in your scripts:
+
+```javascript
+MurmurHash3 = require('imurmurhash');
+```
+
+Quick Example
+-------------
+
+```javascript
+// Create the initial hash
+var hashState = MurmurHash3('string');
+
+// Incrementally add text
+hashState.hash('more strings');
+hashState.hash('even more strings');
+
+// All calls can be chained if desired
+hashState.hash('and').hash('some').hash('more');
+
+// Get a result
+hashState.result();
+// returns 0xe4ccfe6b
+```
+
+Functions
+---------
+
+### MurmurHash3 ([string], [seed])
+Get a hash state object, optionally initialized with the given _string_ and _seed_. _Seed_ must be a positive integer if provided. Calling this function without the `new` keyword will return a cached state object that has been reset. This is safe to use as long as the object is only used from a single thread and no other hashes are created while operating on this one. If this constraint cannot be met, you can use `new` to create a new state object. For example:
+
+```javascript
+// Use the cached object, calling the function again will return the same
+// object (but reset, so the current state would be lost)
+hashState = MurmurHash3();
+...
+
+// Create a new object that can be safely used however you wish. Calling the
+// function again will simply return a new state object, and no state loss
+// will occur, at the cost of creating more objects.
+hashState = new MurmurHash3();
+```
+
+Both methods can be mixed however you like if you have different use cases.
+
+---
+
+### MurmurHash3.prototype.hash (string)
+Incrementally add _string_ to the hash. This can be called as many times as you want for the hash state object, including after a call to `result()`. Returns `this` so calls can be chained.
+
+---
+
+### MurmurHash3.prototype.result ()
+Get the result of the hash as a 32-bit positive integer. This performs the tail and finalizer portions of the algorithm, but does not store the result in the state object. This means that it is perfectly safe to get results and then continue adding strings via `hash`.
+
+```javascript
+// Do the whole string at once
+MurmurHash3('this is a test string').result();
+// 0x70529328
+
+// Do part of the string, get a result, then the other part
+var m = MurmurHash3('this is a');
+m.result();
+// 0xbfc4f834
+m.hash(' test string').result();
+// 0x70529328 (same as above)
+```
+
+---
+
+### MurmurHash3.prototype.reset ([seed])
+Reset the state object for reuse, optionally using the given _seed_ (defaults to 0 like the constructor). Returns `this` so calls can be chained.

+# inflight
+
+Add callbacks to requests in flight to avoid async duplication
+
+## USAGE
+
+```javascript
+var inflight = require('inflight')
+
+// some request that does some stuff
+function req(key, callback) {
+  // key is any random string.  like a url or filename or whatever.
+  //
+  // will return either a falsey value, indicating that the
+  // request for this key is already in flight, or a new callback
+  // which when called will call all callbacks passed to inflightk
+  // with the same key
+  callback = inflight(key, callback)
+
+  // If we got a falsey value back, then there's already a req going
+  if (!callback) return
+
+  // this is where you'd fetch the url or whatever
+  // callback is also once()-ified, so it can safely be assigned
+  // to multiple events etc.  First call wins.
+  setTimeout(function() {
+    callback(null, key)
+  }, 100)
+}
+
+// only assigns a single setTimeout
+// when it dings, all cbs get called
+req('foo', cb1)
+req('foo', cb2)
+req('foo', cb3)
+req('foo', cb4)

+Browser-friendly inheritance fully compatible with standard node.js
+[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
+
+This package exports standard `inherits` from node.js `util` module in
+node environment, but also provides alternative browser-friendly
+implementation through [browser
+field](https://gist.github.com/shtylman/4339901). Alternative
+implementation is a literal copy of standard one located in standalone
+module to avoid requiring of `util`. It also has a shim for old
+browsers with no `Object.create` support.
+
+While keeping you sure you are using standard `inherits`
+implementation in node.js environment, it allows bundlers such as
+[browserify](https://github.com/substack/node-browserify) to not
+include full `util` package to your client code if all you need is
+just `inherits` function. It worth, because browser shim for `util`
+package is large and `inherits` is often the single function you need
+from it.
+
+It's recommended to use this package instead of
+`require('util').inherits` for any code that has chances to be used
+not only in node.js but in browser too.
+
+## usage
+
+```js
+var inherits = require('inherits');
+// then use exactly as the standard one
+```
+
+## note on version ~1.0
+
+Version ~1.0 had completely different motivation and is not compatible
+neither with 2.0 nor with standard node.js `inherits`.
+
+If you are using version ~1.0 and planning to switch to ~2.0, be
+careful:
+
+* new version uses `super_` instead of `super` for referencing
+  superclass
+* new version overwrites current prototype while old one preserves any
+  existing fields on it

+## Goal and Philosophy
+
+<img align="right" alt="Inquirer Logo" src="/assets/inquirer_readme.png" title="Inquirer.js"/>
+
+**`Inquirer.js`** strives to be an easily embeddable and beautiful command line interface for [Node.js](https://nodejs.org/) (and perhaps the "CLI [Xanadu](https://en.wikipedia.org/wiki/Citizen_Kane)").
+
+**`Inquirer.js`** should ease the process of
+- providing *error feedback*
+- *asking questions*
+- *parsing* input
+- *validating* answers
+- managing *hierarchical prompts*
+
+> **Note:** **`Inquirer.js`** provides the user interface and the inquiry session flow. If you're searching for a full blown command line program utility, then check out [commander](https://github.com/visionmedia/commander.js), [vorpal](https://github.com/dthree/vorpal) or [args](https://github.com/leo/args).
+
+
+## [Documentation](#documentation)
+<a name="documentation"></a>
+
+### Installation
+<a name="installation"></a>
+
+``` shell
+npm install inquirer
+```
+
+```javascript
+var inquirer = require('inquirer');
+inquirer.prompt([/* Pass your questions in here */]).then(function (answers) {
+	// Use user feedback for... whatever!!
+});
+```
+
+<a name="examples"></a>
+### Examples (Run it and see it)
+Check out the `examples/` folder for code and interface examples.
+
+``` shell
+node examples/pizza.js
+node examples/checkbox.js
+# etc...
+```
+
+
+### Methods
+<a name="methods"></a>
+#### `inquirer.prompt(questions) -> promise`
+
+Launch the prompt interface (inquiry session)
+
+- **questions** (Array) containing [Question Object](#question) (using the [reactive interface](#reactive-interface), you can also pass a `Rx.Observable` instance)
+- returns a **Promise**
+
+#### `inquirer.registerPrompt(name, prompt)`
+
+Register prompt plugins under `name`.
+
+- **name** (string) name of the this new prompt. (used for question `type`)
+- **prompt** (object) the prompt object itself (the plugin)
+
+#### `inquirer.createPromptModule() -> prompt function`
+
+Create a self contained inquirer module. If you don't want to affect other libraries that also rely on inquirer when you overwrite or add new prompt types.
+
+```js
+var prompt = inquirer.createPromptModule();
+
+prompt(questions).then(/* ... */);
+```
+
+### Objects
+<a name="objects"></a>
+
+#### Question
+<a name="questions"></a>
+A question object is a `hash` containing question related values:
+
+- **type**: (String) Type of the prompt. Defaults: `input` - Possible values: `input`, `confirm`,
+`list`, `rawlist`, `expand`, `checkbox`, `password`, `editor`
+- **name**: (String) The name to use when storing the answer in the answers hash. If the name contains periods, it will define a path in the answers hash.
+- **message**: (String|Function) The question to print. If defined as a function, the first parameter will be the current inquirer session answers.
+- **default**: (String|Number|Array|Function) Default value(s) to use if nothing is entered, or a function that returns the default value(s). If defined as a function, the first parameter will be the current inquirer session answers.
+- **choices**: (Array|Function) Choices array or a function returning a choices array. If defined as a function, the first parameter will be the current inquirer session answers.
+Array values can be simple `strings`, or `objects` containing a `name` (to display in list), a `value` (to save in the answers hash) and a `short` (to display after selection) properties. The choices array can also contain [a `Separator`](#separator).
+- **validate**: (Function) Receive the user input and answers hash. Should return `true` if the value is valid, and an error message (`String`) otherwise. If `false` is returned, a default error message is provided.
+- **filter**: (Function) Receive the user input and return the filtered value to be used inside the program. The value returned will be added to the _Answers_ hash.
+- **when**: (Function, Boolean) Receive the current user answers hash and should return `true` or `false` depending on whether or not this question should be asked. The value can also be a simple boolean.
+- **pageSize**: (Number) Change the number of lines that will be rendered when using `list`, `rawList`, `expand` or `checkbox`.
+- **prefix**: (String) Change the default _prefix_ message.
+- **suffix**: (String) Change the default _suffix_ message.
+
+`default`, `choices`(if defined as functions), `validate`, `filter` and `when` functions can be called asynchronous. Either return a promise or use `this.async()` to get a callback you'll call with the final value.
+
+``` javascript
+{
+  /* Preferred way: with promise */
+  filter: function () {
+    return new Promise(/* etc... */);
+  },
+
+  /* Legacy way: with this.async */
+  validate: function (input) {
+    // Declare function as asynchronous, and save the done callback
+    var done = this.async();
+
+    // Do async stuff
+    setTimeout(function () {
+      if (typeof input !== 'number') {
+        // Pass the return value in the done callback
+        done('You need to provide a number');
+        return;
+      }
+      // Pass the return value in the done callback
+      done(null, true);
+    }, 3000);
+  }
+}
+```
+
+### Answers
+<a name="answers"></a>
+A key/value hash containing the client answers in each prompt.
+
+- **Key** The `name` property of the _question_ object
+- **Value** (Depends on the prompt)
+  - `confirm`: (Boolean)
+  - `input` : User input (filtered if `filter` is defined) (String)
+  - `rawlist`, `list` : Selected choice value (or name if no value specified) (String)
+
+### Separator
+<a name="separator"></a>
+A separator can be added to any `choices` array:
+
+```
+// In the question object
+choices: [ "Choice A", new inquirer.Separator(), "choice B" ]
+
+// Which'll be displayed this way
+[?] What do you want to do?
+ > Order a pizza
+   Make a reservation
+   --------
+   Ask opening hours
+   Talk to the receptionist
+```
+
+The constructor takes a facultative `String` value that'll be use as the separator. If omitted, the separator will be `--------`.
+
+Separator instances have a property `type` equal to `separator`. This should allow tools façading Inquirer interface from detecting separator types in lists.
+
+<a name="prompt"></a>
+### Prompt types
+---------------------
+
+> **Note:**: _allowed options written inside square brackets (`[]`) are optional. Others are required._
+
+#### List - `{type: 'list'}`
+
+Take `type`, `name`, `message`, `choices`[, `default`, `filter`] properties. (Note that
+default must be the choice `index` in the array or a choice `value`)
+
+![List prompt](assets/screenshots/list-prompt.png)
+
+---
+
+#### Raw List - `{type: 'rawlist'}`
+
+Take `type`, `name`, `message`, `choices`[, `default`, `filter`] properties. (Note that
+default must the choice `index` in the array)
+
+![Raw list prompt](assets/screenshots/rawlist-prompt.png)
+
+---
+
+#### Expand - `{type: 'expand'}`
+
+Take `type`, `name`, `message`, `choices`[, `default`] properties. (Note that
+default must be the choice `index` in the array. If `default` key not provided, then `help` will be used as default choice)
+
+Note that the `choices` object will take an extra parameter called `key` for the `expand` prompt. This parameter must be a single (lowercased) character. The `h` option is added by the prompt and shouldn't be defined by the user.
+
+See `examples/expand.js` for a running example.
+
+![Expand prompt closed](assets/screenshots/expand-prompt-1.png)
+![Expand prompt expanded](assets/screenshots/expand-prompt-2.png)
+
+---
+
+#### Checkbox - `{type: 'checkbox'}`
+
+Take `type`, `name`, `message`, `choices`[, `filter`, `validate`, `default`] properties. `default` is expected to be an Array of the checked choices value.
+
+Choices marked as `{checked: true}` will be checked by default.
+
+Choices whose property `disabled` is truthy will be unselectable. If `disabled` is a string, then the string will be outputted next to the disabled choice, otherwise it'll default to `"Disabled"`. The `disabled` property can also be a synchronous function receiving the current answers as argument and returning a boolean or a string.
+
+![Checkbox prompt](assets/screenshots/checkbox-prompt.png)
+
+---
+
+#### Confirm - `{type: 'confirm'}`
+
+Take `type`, `name`, `message`[, `default`] properties. `default` is expected to be a boolean if used.
+
+![Confirm prompt](assets/screenshots/confirm-prompt.png)
+
+---
+
+#### Input - `{type: 'input'}`
+
+Take `type`, `name`, `message`[, `default`, `filter`, `validate`] properties.
+
+![Input prompt](assets/screenshots/input-prompt.png)
+
+---
+
+#### Password - `{type: 'password'}`
+
+Take `type`, `name`, `message`[, `default`, `filter`, `validate`] properties.
+
+![Password prompt](assets/screenshots/password-prompt.png)
+
+---
+
+#### Editor - `{type: 'editor'}`
+
+Take `type`, `name`, `message`[, `default`, `filter`, `validate`] properties
+
+Launches an instance of the users preferred editor on a temporary file. Once the user exits their editor, the contents of the temporary file are read in as the result. The editor to use is determined by reading the $VISUAL or $EDITOR environment variables. If neither of those are present, notepad (on Windows) or vim (Linux or Mac) is used.
+
+<a name="layouts"></a>
+## User Interfaces and layouts
+
+
+Along with the prompts, Inquirer offers some basic text UI.
+
+#### Bottom Bar - `inquirer.ui.BottomBar`
+
+This UI present a fixed text at the bottom of a free text zone. This is useful to keep a message to the bottom of the screen while outputting command outputs on the higher section.
+
+```javascript
+var ui = new inquirer.ui.BottomBar();
+
+// pipe a Stream to the log zone
+outputStream.pipe(ui.log);
+
+// Or simply write output
+ui.log.write('something just happened.');
+ui.log.write('Almost over, standby!');
+
+// During processing, update the bottom bar content to display a loader
+// or output a progress bar, etc
+ui.updateBottomBar('new bottom bar content');
+```
+
+<a name="reactive"></a>
+## Reactive interface
+
+
+Internally, Inquirer uses the [JS reactive extension](https://github.com/Reactive-Extensions/RxJS) to handle events and async flows.
+
+This mean you can take advantage of this feature to provide more advanced flows. For example, you can dynamically add questions to be asked:
+
+```js
+var prompts = new Rx.Subject();
+inquirer.prompt(prompts);
+
+// At some point in the future, push new questions
+prompts.onNext({ /* question... */ });
+prompts.onNext({ /* question... */ });
+
+// When you're done
+prompts.onCompleted();
+```
+
+And using the return value `process` property, you can access more fine grained callbacks:
+
+```js
+inquirer.prompt(prompts).ui.process.subscribe(
+  onEachAnswer,
+  onError,
+  onComplete
+);
+```
+
+## Support (OS Terminals)
+<a name="support"></a>
+
+You should expect mostly good support for the CLI below. This does not mean we won't
+look at issues found on other command line - feel free to report any!
+
+- **Mac OS**:
+  - Terminal.app
+  - iTerm
+- **Windows**:
+  - [ConEmu](https://conemu.github.io/)
+  - cmd.exe
+  - Powershell
+  - Cygwin
+- **Linux (Ubuntu, openSUSE, Arch Linux, etc)**:
+  - gnome-terminal (Terminal GNOME)
+  - konsole
+
+

+
+## Why not use `Buffer.isBuffer`?
+
+This module lets you check if an object is a `Buffer` without using `Buffer.isBuffer` (which includes the whole [buffer](https://github.com/feross/buffer) module in [browserify](http://browserify.org/)).
+
+It's future-proof and works in node too!
+
+## install
+
+```bash
+npm install is-buffer
+```
+
+## usage
+
+```js
+var isBuffer = require('is-buffer')
+
+isBuffer(new Buffer(4)) // true
+
+isBuffer(undefined) // false
+isBuffer(null) // false
+isBuffer('') // false
+isBuffer(true) // false
+isBuffer(false) // false
+isBuffer(0) // false
+isBuffer(1) // false
+isBuffer(1.0) // false
+isBuffer('string') // false
+isBuffer({}) // false
+isBuffer(function foo () {}) // false

+
+A [Node](https://nodejs.org/) module to check if a module ID is resolvable with [`require()`](https://nodejs.org/api/globals.html#globals_require)
+
+```javascript
+const isResolvable = require('is-resolvable');
+
+isResolvable('fs'); //=> true
+isResolvable('path'); //=> true
+
+// When `./index.js` exists
+isResolvable('./index.js') //=> true
+isResolvable('./index') //=> true
+isResolvable('.') //=> true
+```
+
+## Installation
+
+[Use npm.](https://docs.npmjs.com/cli/install)
+
+```
+npm install is-resolvable
+```
+
+## API
+
+```javascript
+const isResolvable = require('is-resolvable');
+```
+
+### isResolvable(*moduleId*)
+
+*moduleId*: `String` (module ID)  
+Return: `Boolean`
+
+It returns `true` if `require()` can load a file form a given module ID, otherwise `false`.
+
+```javascript
+const isResolvable = require('is-resolvable');
+
+// When `./foo.json` exists
+isResolvable('./foo.json'); //=> true
+isResolvable('./foo'); //=> true
+
+isResolvable('./foo.js'); //=> false
+
+
+// When `lodash` module is installed but `underscore` isn't
+isResolvable('lodash'); //=> true
+isResolvable('underscore'); //=> false
+
+// When `readable-stream` module is installed
+isResolvable('readable-stream/readable'); //=> true
+isResolvable('readable-stream/writable'); //=> true
+```

+# isexe
+
+Minimal module to check if a file is executable, and a normal file.
+
+Uses `fs.stat` and tests against the `PATHEXT` environment variable on
+Windows.
+
+## USAGE
+
+```javascript
+var isexe = require('isexe')
+isexe('some-file-name', function (err, isExe) {
+  if (err) {
+    console.error('probably file does not exist or something', err)
+  } else if (isExe) {
+    console.error('this thing can be run')
+  } else {
+    console.error('cannot be run')
+  }
+})
+
+// same thing but synchronous, throws errors
+var isExe = isexe.sync('some-file-name')
+
+// treat errors as just "not executable"
+isexe('maybe-missing-file', { ignoreErrors: true }, callback)
+var isExe = isexe.sync('maybe-missing-file', { ignoreErrors: true })
+```
+
+## API
+
+### `isexe(path, [options], [callback])`
+
+Check if the path is executable.  If no callback provided, and a
+global `Promise` object is available, then a Promise will be returned.
+
+Will raise whatever errors may be raised by `fs.stat`, unless
+`options.ignoreErrors` is set to true.
+
+### `isexe.sync(path, [options])`
+
+Same as `isexe` but returns the value and throws any errors raised.
+
+### Options
+
+* `ignoreErrors` Treat all errors as "no, this is not executable", but
+  don't raise them.
+* `uid` Number to use as the user id
+* `gid` Number to use as the group id
+* `pathExt` List of path extensions to use instead of `PATHEXT`
+  environment variable on Windows.

+Overview [![Build Status](https://travis-ci.org/lydell/js-tokens.svg?branch=master)](https://travis-ci.org/lydell/js-tokens)
+========
+
+A regex that tokenizes JavaScript.
+
+```js
+var jsTokens = require("js-tokens").default
+
+var jsString = "var foo=opts.foo;\n..."
+
+jsString.match(jsTokens)
+// ["var", " ", "foo", "=", "opts", ".", "foo", ";", "\n", ...]
+```
+
+
+Installation
+============
+
+`npm install js-tokens`
+
+```js
+import jsTokens from "js-tokens"
+// or:
+var jsTokens = require("js-tokens").default
+```
+
+
+Usage
+=====
+
+### `jsTokens` ###
+
+A regex with the `g` flag that matches JavaScript tokens.
+
+The regex _always_ matches, even invalid JavaScript and the empty string.
+
+The next match is always directly after the previous.
+
+### `var token = matchToToken(match)` ###
+
+```js
+import {matchToToken} from "js-tokens"
+// or:
+var matchToToken = require("js-tokens").matchToToken
+```
+
+Takes a `match` returned by `jsTokens.exec(string)`, and returns a `{type:
+String, value: String}` object. The following types are available:
+
+- string
+- comment
+- regex
+- number
+- name
+- punctuator
+- whitespace
+- invalid
+
+Multi-line comments and strings also have a `closed` property indicating if the
+token was closed or not (see below).
+
+Comments and strings both come in several flavors. To distinguish them, check if
+the token starts with `//`, `/*`, `'`, `"` or `` ` ``.
+
+Names are ECMAScript IdentifierNames, that is, including both identifiers and
+keywords. You may use [is-keyword-js] to tell them apart.
+
+Whitespace includes both line terminators and other whitespace.
+
+[is-keyword-js]: https://github.com/crissdev/is-keyword-js
+
+
+ECMAScript support
+==================
+
+The intention is to always support the latest stable ECMAScript version.
+
+If adding support for a newer version requires changes, a new version with a
+major verion bump will be released.
+
+Currently, [ECMAScript 2017] is supported.
+
+[ECMAScript 2017]: https://www.ecma-international.org/ecma-262/8.0/index.html
+
+
+Invalid code handling
+=====================
+
+Unterminated strings are still matched as strings. JavaScript strings cannot
+contain (unescaped) newlines, so unterminated strings simply end at the end of
+the line. Unterminated template strings can contain unescaped newlines, though,
+so they go on to the end of input.
+
+Unterminated multi-line comments are also still matched as comments. They
+simply go on to the end of the input.
+
+Unterminated regex literals are likely matched as division and whatever is
+inside the regex.
+
+Invalid ASCII characters have their own capturing group.
+
+Invalid non-ASCII characters are treated as names, to simplify the matching of
+names (except unicode spaces which are treated as whitespace).
+
+Regex literals may contain invalid regex syntax. They are still matched as
+regex literals. They may also contain repeated regex flags, to keep the regex
+simple.
+
+Strings may contain invalid escape sequences.
+
+
+Limitations
+===========
+
+Tokenizing JavaScript using regexes—in fact, _one single regex_—won’t be
+perfect. But that’s not the point either.
+
+You may compare jsTokens with [esprima] by using `esprima-compare.js`.
+See `npm run esprima-compare`!
+
+[esprima]: http://esprima.org/
+
+### Template string interpolation ###
+
+Template strings are matched as single tokens, from the starting `` ` `` to the
+ending `` ` ``, including interpolations (whose tokens are not matched
+individually).
+
+Matching template string interpolations requires recursive balancing of `{` and
+`}`—something that JavaScript regexes cannot do. Only one level of nesting is
+supported.
+
+### Division and regex literals collision ###
+
+Consider this example:
+
+```js
+var g = 9.82
+var number = bar / 2/g
+
+var regex = / 2/g
+```
+
+A human can easily understand that in the `number` line we’re dealing with
+division, and in the `regex` line we’re dealing with a regex literal. How come?
+Because humans can look at the whole code to put the `/` characters in context.
+A JavaScript regex cannot. It only sees forwards.
+
+When the `jsTokens` regex scans throught the above, it will see the following
+at the end of both the `number` and `regex` rows:
+
+```js
+/ 2/g
+```
+
+It is then impossible to know if that is a regex literal, or part of an
+expression dealing with division.
+
+Here is a similar case:
+
+```js
+foo /= 2/g
+foo(/= 2/g)
+```
+
+The first line divides the `foo` variable with `2/g`. The second line calls the
+`foo` function with the regex literal `/= 2/g`. Again, since `jsTokens` only
+sees forwards, it cannot tell the two cases apart.
+
+There are some cases where we _can_ tell division and regex literals apart,
+though.
+
+First off, we have the simple cases where there’s only one slash in the line:
+
+```js
+var foo = 2/g
+foo /= 2
+```
+
+Regex literals cannot contain newlines, so the above cases are correctly
+identified as division. Things are only problematic when there are more than
+one non-comment slash in a single line.
+
+Secondly, not every character is a valid regex flag.
+
+```js
+var number = bar / 2/e
+```
+
+The above example is also correctly identified as division, because `e` is not a
+valid regex flag. I initially wanted to future-proof by allowing `[a-zA-Z]*`
+(any letter) as flags, but it is not worth it since it increases the amount of
+ambigous cases. So only the standard `g`, `m`, `i`, `y` and `u` flags are
+allowed. This means that the above example will be identified as division as
+long as you don’t rename the `e` variable to some permutation of `gmiyu` 1 to 5
+characters long.
+
+Lastly, we can look _forward_ for information.
+
+- If the token following what looks like a regex literal is not valid after a
+  regex literal, but is valid in a division expression, then the regex literal
+  is treated as division instead. For example, a flagless regex cannot be
+  followed by a string, number or name, but all of those three can be the
+  denominator of a division.
+- Generally, if what looks like a regex literal is followed by an operator, the
+  regex literal is treated as division instead. This is because regexes are
+  seldomly used with operators (such as `+`, `*`, `&&` and `==`), but division
+  could likely be part of such an expression.
+
+Please consult the regex source and the test cases for precise information on
+when regex or division is matched (should you need to know). In short, you
+could sum it up as:
+
+If the end of a statement looks like a regex literal (even if it isn’t), it
+will be treated as one. Otherwise it should work as expected (if you write sane
+code).

+JS-YAML - YAML 1.2 parser / writer for JavaScript
+=================================================
+
+[![Build Status](https://travis-ci.org/nodeca/js-yaml.svg?branch=master)](https://travis-ci.org/nodeca/js-yaml)
+[![NPM version](https://img.shields.io/npm/v/js-yaml.svg)](https://www.npmjs.org/package/js-yaml)
+
+__[Online Demo](http://nodeca.github.com/js-yaml/)__
+
+
+This is an implementation of [YAML](http://yaml.org/), a human-friendly data
+serialization language. Started as [PyYAML](http://pyyaml.org/) port, it was
+completely rewritten from scratch. Now it's very fast, and supports 1.2 spec.
+
+
+Installation
+------------
+
+### YAML module for node.js
+
+```
+npm install js-yaml
+```
+
+
+### CLI executable
+
+If you want to inspect your YAML files from CLI, install js-yaml globally:
+
+```
+npm install -g js-yaml
+```
+
+#### Usage
+
+```
+usage: js-yaml [-h] [-v] [-c] [-t] file
+
+Positional arguments:
+  file           File with YAML document(s)
+
+Optional arguments:
+  -h, --help     Show this help message and exit.
+  -v, --version  Show program's version number and exit.
+  -c, --compact  Display errors in compact mode
+  -t, --trace    Show stack trace on error
+```
+
+
+### Bundled YAML library for browsers
+
+``` html
+<!-- esprima required only for !!js/function -->
+<script src="esprima.js"></script>
+<script src="js-yaml.min.js"></script>
+<script type="text/javascript">
+var doc = jsyaml.load('greeting: hello\nname: world');
+</script>
+```
+
+Browser support was done mostly for the online demo. If you find any errors - feel
+free to send pull requests with fixes. Also note, that IE and other old browsers
+needs [es5-shims](https://github.com/kriskowal/es5-shim) to operate.
+
+Notes:
+
+1. We have no resources to support browserified version. Don't expect it to be
+   well tested. Don't expect fast fixes if something goes wrong there.
+2. `!!js/function` in browser bundle will not work by default. If you really need
+   it - load `esprima` parser first (via amd or directly).
+3. `!!bin` in browser will return `Array`, because browsers do not support
+   node.js `Buffer` and adding Buffer shims is completely useless on practice.
+
+
+API
+---
+
+Here we cover the most 'useful' methods. If you need advanced details (creating
+your own tags), see [wiki](https://github.com/nodeca/js-yaml/wiki) and
+[examples](https://github.com/nodeca/js-yaml/tree/master/examples) for more
+info.
+
+``` javascript
+yaml = require('js-yaml');
+fs   = require('fs');
+
+// Get document, or throw exception on error
+try {
+  var doc = yaml.safeLoad(fs.readFileSync('/home/ixti/example.yml', 'utf8'));
+  console.log(doc);
+} catch (e) {
+  console.log(e);
+}
+```
+
+
+### safeLoad (string [ , options ])
+
+**Recommended loading way.** Parses `string` as single YAML document. Returns a JavaScript
+object or throws `YAMLException` on error. By default, does not support regexps,
+functions and undefined. This method is safe for untrusted data.
+
+options:
+
+- `filename` _(default: null)_ - string to be used as a file path in
+  error/warning messages.
+- `onWarning` _(default: null)_ - function to call on warning messages.
+  Loader will throw on warnings if this function is not provided.
+- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ - specifies a schema to use.
+  - `FAILSAFE_SCHEMA` - only strings, arrays and plain objects:
+    http://www.yaml.org/spec/1.2/spec.html#id2802346
+  - `JSON_SCHEMA` - all JSON-supported types:
+    http://www.yaml.org/spec/1.2/spec.html#id2803231
+  - `CORE_SCHEMA` - same as `JSON_SCHEMA`:
+    http://www.yaml.org/spec/1.2/spec.html#id2804923
+  - `DEFAULT_SAFE_SCHEMA` - all supported YAML types, without unsafe ones
+    (`!!js/undefined`, `!!js/regexp` and `!!js/function`):
+    http://yaml.org/type/
+  - `DEFAULT_FULL_SCHEMA` - all supported YAML types.
+- `json` _(default: false)_ - compatibility with JSON.parse behaviour. If true, then duplicate keys in a mapping will override values rather than throwing an error.
+
+NOTE: This function **does not** understand multi-document sources, it throws
+exception on those.
+
+NOTE: JS-YAML **does not** support schema-specific tag resolution restrictions.
+So, the JSON schema is not as strictly defined in the YAML specification.
+It allows numbers in any notation, use `Null` and `NULL` as `null`, etc.
+The core schema also has no such restrictions. It allows binary notation for integers.
+
+
+### load (string [ , options ])
+
+**Use with care with untrusted sources**. The same as `safeLoad()` but uses
+`DEFAULT_FULL_SCHEMA` by default - adds some JavaScript-specific types:
+`!!js/function`, `!!js/regexp` and `!!js/undefined`. For untrusted sources, you
+must additionally validate object structure to avoid injections:
+
+``` javascript
+var untrusted_code = '"toString": !<tag:yaml.org,2002:js/function> "function (){very_evil_thing();}"';
+
+// I'm just converting that string, what could possibly go wrong?
+require('js-yaml').load(untrusted_code) + ''
+```
+
+
+### safeLoadAll (string [, iterator] [, options ])
+
+Same as `safeLoad()`, but understands multi-document sources. Applies
+`iterator` to each document if specified, or returns array of documents.
+
+``` javascript
+var yaml = require('js-yaml');
+
+yaml.safeLoadAll(data, function (doc) {
+  console.log(doc);
+});
+```
+
+
+### loadAll (string [, iterator] [ , options ])
+
+Same as `safeLoadAll()` but uses `DEFAULT_FULL_SCHEMA` by default.
+
+
+### safeDump (object [ , options ])
+
+Serializes `object` as a YAML document. Uses `DEFAULT_SAFE_SCHEMA`, so it will
+throw an exception if you try to dump regexps or functions. However, you can
+disable exceptions by setting the `skipInvalid` option to `true`.
+
+options:
+
+- `indent` _(default: 2)_ - indentation width to use (in spaces).
+- `skipInvalid` _(default: false)_ - do not throw on invalid types (like function
+  in the safe schema) and skip pairs and single values with such types.
+- `flowLevel` (default: -1) - specifies level of nesting, when to switch from
+  block to flow style for collections. -1 means block style everwhere
+- `styles` - "tag" => "style" map. Each tag may have own set of styles.
+- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ specifies a schema to use.
+- `sortKeys` _(default: `false`)_ - if `true`, sort keys when dumping YAML. If a
+  function, use the function to sort the keys.
+- `lineWidth` _(default: `80`)_ - set max line width.
+- `noRefs` _(default: `false`)_ - if `true`, don't convert duplicate objects into references
+- `noCompatMode` _(default: `false`)_ - if `true` don't try to be compatible with older
+  yaml versions. Currently: don't quote "yes", "no" and so on, as required for YAML 1.1
+- `condenseFlow` _(default: `false`)_ - if `true` flow sequences will be condensed, omitting the space between `a, b`. Eg. `'[a,b]'`, and omitting the space between `key: value` and quoting the key. Eg. `'{"a":b}'` Can be useful when using yaml for pretty URL query params as spaces are %-encoded.
+
+The following table show availlable styles (e.g. "canonical",
+"binary"...) available for each tag (.e.g. !!null, !!int ...). Yaml
+ouput is shown on the right side after `=>` (default setting) or `->`:
+
+``` none
+!!null
+  "canonical"   -> "~"
+  "lowercase"   => "null"
+  "uppercase"   -> "NULL"
+  "camelcase"   -> "Null"
+
+!!int
+  "binary"      -> "0b1", "0b101010", "0b1110001111010"
+  "octal"       -> "01", "052", "016172"
+  "decimal"     => "1", "42", "7290"
+  "hexadecimal" -> "0x1", "0x2A", "0x1C7A"
+
+!!bool
+  "lowercase"   => "true", "false"
+  "uppercase"   -> "TRUE", "FALSE"
+  "camelcase"   -> "True", "False"
+
+!!float
+  "lowercase"   => ".nan", '.inf'
+  "uppercase"   -> ".NAN", '.INF'
+  "camelcase"   -> ".NaN", '.Inf'
+```
+
+Example:
+
+``` javascript
+safeDump (object, {
+  'styles': {
+    '!!null': 'canonical' // dump null as ~
+  },
+  'sortKeys': true        // sort object keys
+});
+```
+
+### dump (object [ , options ])
+
+Same as `safeDump()` but without limits (uses `DEFAULT_FULL_SCHEMA` by default).
+
+
+Supported YAML types
+--------------------
+
+The list of standard YAML tags and corresponding JavaScipt types. See also
+[YAML tag discussion](http://pyyaml.org/wiki/YAMLTagDiscussion) and
+[YAML types repository](http://yaml.org/type/).
+
+```
+!!null ''                   # null
+!!bool 'yes'                # bool
+!!int '3...'                # number
+!!float '3.14...'           # number
+!!binary '...base64...'     # buffer
+!!timestamp 'YYYY-...'      # date
+!!omap [ ... ]              # array of key-value pairs
+!!pairs [ ... ]             # array or array pairs
+!!set { ... }               # array of objects with given keys and null values
+!!str '...'                 # string
+!!seq [ ... ]               # array
+!!map { ... }               # object
+```
+
+**JavaScript-specific tags**
+
+```
+!!js/regexp /pattern/gim            # RegExp
+!!js/undefined ''                   # Undefined
+!!js/function 'function () {...}'   # Function
+```
+
+Caveats
+-------
+
+Note, that you use arrays or objects as key in JS-YAML. JS does not allow objects
+or arrays as keys, and stringifies (by calling `toString()` method) them at the
+moment of adding them.
+
+``` yaml
+---
+? [ foo, bar ]
+: - baz
+? { foo: bar }
+: - baz
+  - baz
+```
+
+``` javascript
+{ "foo,bar": ["baz"], "[object Object]": ["baz", "baz"] }
+```
+
+Also, reading of properties on implicit block mapping keys is not supported yet.
+So, the following YAML document cannot be loaded.
+
+``` yaml
+&anchor foo:
+  foo: bar
+  *anchor: duplicate key
+  baz: bat
+  *anchor: duplicate key
+```
+
+
+Breaking changes in 2.x.x -> 3.x.x
+----------------------------------
+
+If you have not used __custom__ tags or loader classes and not loaded yaml
+files via `require()`, no changes are needed. Just upgrade the library.
+
+Otherwise, you should:
+
+1. Replace all occurrences of `require('xxxx.yml')` by `fs.readFileSync()` +
+  `yaml.safeLoad()`.
+2. rewrite your custom tags constructors and custom loader
+  classes, to conform the new API. See
+  [examples](https://github.com/nodeca/js-yaml/tree/master/examples) and
+  [wiki](https://github.com/nodeca/js-yaml/wiki) for details.

+# json-schema-traverse
+Traverse JSON Schema passing each schema object to callback
+
+[![Build Status](https://travis-ci.org/epoberezkin/json-schema-traverse.svg?branch=master)](https://travis-ci.org/epoberezkin/json-schema-traverse)
+[![npm version](https://badge.fury.io/js/json-schema-traverse.svg)](https://www.npmjs.com/package/json-schema-traverse)
+[![Coverage Status](https://coveralls.io/repos/github/epoberezkin/json-schema-traverse/badge.svg?branch=master)](https://coveralls.io/github/epoberezkin/json-schema-traverse?branch=master)
+
+
+## Install
+
+```
+npm install json-schema-traverse
+```
+
+
+## Usage
+
+```javascript
+const traverse = require('json-schema-traverse');
+const schema = {
+  properties: {
+    foo: {type: 'string'},
+    bar: {type: 'integer'}
+  }
+};
+
+traverse(schema, cb);
+// cb is called 3 times with:
+// 1. root schema
+// 2. {type: 'string'}
+// 3. {type: 'integer'}
+```
+
+Callback function is called for each schema object (not including draft-06 boolean schemas), including the root schema. Schema references ($ref) are not resolved, they are passed as is.
+
+Callback is passed these parameters:
+
+- _schema_: the current schema object
+- _JSON pointer_: from the root schema to the current schema object
+- _root schema_: the schema passed to `traverse` object
+- _parent JSON pointer_: from the root schema to the parent schema object (see below)
+- _parent keyword_: the keyword inside which this schema appears (e.g. `properties`, `anyOf`, etc.)
+- _parent schema_: not necessarily parent object/array; in the example above the parent schema for `{type: 'string'}` is the root schema
+- _index/property_: index or property name in the array/object containing multiple schemas; in the example above for `{type: 'string'}` the property name is `'foo'`
+
+
+## Traverse objects in all unknown keywords
+
+```javascript
+const traverse = require('json-schema-traverse');
+const schema = {
+  mySchema: {
+    minimum: 1,
+    maximum: 2
+  }
+};
+
+traverse(schema, {allKeys: true}, cb);
+// cb is called 2 times with:
+// 1. root schema
+// 2. mySchema
+```
+
+Without option `allKeys: true` callback will be called only with root schema.
+

+# json-stable-stringify
+
+This is the same as https://github.com/substack/json-stable-stringify but it doesn't depend on libraries without licenses (jsonify).
+
+deterministic version of `JSON.stringify()` so you can get a consistent hash
+from stringified results
+
+You can also pass in a custom comparison function.
+
+[![browser support](https://ci.testling.com/substack/json-stable-stringify.png)](https://ci.testling.com/substack/json-stable-stringify)
+
+[![build status](https://secure.travis-ci.org/substack/json-stable-stringify.png)](http://travis-ci.org/substack/json-stable-stringify)
+
+# example
+
+``` js
+var stringify = require('json-stable-stringify');
+var obj = { c: 8, b: [{z:6,y:5,x:4},7], a: 3 };
+console.log(stringify(obj));
+```
+
+output:
+
+```
+{"a":3,"b":[{"x":4,"y":5,"z":6},7],"c":8}
+```
+
+# methods
+
+``` js
+var stringify = require('json-stable-stringify')
+```
+
+## var str = stringify(obj, opts)
+
+Return a deterministic stringified string `str` from the object `obj`.
+
+## options
+
+### cmp
+
+If `opts` is given, you can supply an `opts.cmp` to have a custom comparison
+function for object keys. Your function `opts.cmp` is called with these
+parameters:
+
+``` js
+opts.cmp({ key: akey, value: avalue }, { key: bkey, value: bvalue })
+```
+
+For example, to sort on the object key names in reverse order you could write:
+
+``` js
+var stringify = require('json-stable-stringify');
+
+var obj = { c: 8, b: [{z:6,y:5,x:4},7], a: 3 };
+var s = stringify(obj, function (a, b) {
+    return a.key < b.key ? 1 : -1;
+});
+console.log(s);
+```
+
+which results in the output string:
+
+```
+{"c":8,"b":[{"z":6,"y":5,"x":4},7],"a":3}
+```
+
+Or if you wanted to sort on the object values in reverse order, you could write:
+
+```
+var stringify = require('json-stable-stringify');
+
+var obj = { d: 6, c: 5, b: [{z:3,y:2,x:1},9], a: 10 };
+var s = stringify(obj, function (a, b) {
+    return a.value < b.value ? 1 : -1;
+});
+console.log(s);
+```
+
+which outputs:
+
+```
+{"d":6,"c":5,"b":[{"z":3,"y":2,"x":1},9],"a":10}
+```
+
+### space
+
+If you specify `opts.space`, it will indent the output for pretty-printing.
+Valid values are strings (e.g. `{space: \t}`) or a number of spaces
+(`{space: 3}`).
+
+For example:
+
+```js
+var obj = { b: 1, a: { foo: 'bar', and: [1, 2, 3] } };
+var s = stringify(obj, { space: '  ' });
+console.log(s);
+```
+
+which outputs:
+
+```
+{
+  "a": {
+    "and": [
+      1,
+      2,
+      3
+    ],
+    "foo": "bar"
+  },
+  "b": 1
+}
+```
+
+### replacer
+
+The replacer parameter is a function `opts.replacer(key, value)` that behaves
+the same as the replacer
+[from the core JSON object](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Using_native_JSON#The_replacer_parameter).

+# levn [![Build Status](https://travis-ci.org/gkz/levn.png)](https://travis-ci.org/gkz/levn) <a name="levn" />
+__Light ECMAScript (JavaScript) Value Notation__
+Levn is a library which allows you to parse a string into a JavaScript value based on an expected type. It is meant for short amounts of human entered data (eg. config files, command line arguments).
+
+Levn aims to concisely describe JavaScript values in text, and allow for the extraction and validation of those values. Levn uses [type-check](https://github.com/gkz/type-check) for its type format, and to validate the results. MIT license. Version 0.3.0.
+
+__How is this different than JSON?__ levn is meant to be written by humans only, is (due to the previous point) much more concise, can be validated against supplied types, has regex and date literals, and can easily be extended with custom types. On the other hand, it is probably slower and thus less efficient at transporting large amounts of data, which is fine since this is not its purpose.
+
+    npm install levn
+
+For updates on levn, [follow me on twitter](https://twitter.com/gkzahariev).
+
+
+## Quick Examples
+
+```js
+var parse = require('levn').parse;
+parse('Number', '2');      // 2
+parse('String', '2');      // '2'
+parse('String', 'levn');   // 'levn'
+parse('String', 'a b');    // 'a b'
+parse('Boolean', 'true');  // true
+
+parse('Date', '#2011-11-11#'); // (Date object)
+parse('Date', '2011-11-11');   // (Date object)
+parse('RegExp', '/[a-z]/gi');  // /[a-z]/gi
+parse('RegExp', 're');         // /re/
+parse('Int', '2');             // 2
+
+parse('Number | String', 'str'); // 'str'
+parse('Number | String', '2');   // 2
+
+parse('[Number]', '[1,2,3]');                      // [1,2,3]
+parse('(String, Boolean)', '(hi, false)');         // ['hi', false]
+parse('{a: String, b: Number}', '{a: str, b: 2}'); // {a: 'str', b: 2}
+
+// at the top level, you can ommit surrounding delimiters
+parse('[Number]', '1,2,3');                      // [1,2,3]
+parse('(String, Boolean)', 'hi, false');         // ['hi', false]
+parse('{a: String, b: Number}', 'a: str, b: 2'); // {a: 'str', b: 2}
+
+// wildcard - auto choose type
+parse('*', '[hi,(null,[42]),{k: true}]'); // ['hi', [null, [42]], {k: true}]
+```
+## Usage
+
+`require('levn');` returns an object that exposes three properties. `VERSION` is the current version of the library as a string. `parse` and `parsedTypeParse` are functions.
+
+```js
+// parse(type, input, options);
+parse('[Number]', '1,2,3'); // [1, 2, 3]
+
+// parsedTypeParse(parsedType, input, options);
+var parsedType = require('type-check').parseType('[Number]');
+parsedTypeParse(parsedType, '1,2,3'); // [1, 2, 3]
+```
+
+### parse(type, input, options)
+
+`parse` casts the string `input` into a JavaScript value according to the specified `type` in the [type format](https://github.com/gkz/type-check#type-format) (and taking account the optional `options`) and returns the resulting JavaScript value.
+
+##### arguments
+* type - `String` - the type written in the [type format](https://github.com/gkz/type-check#type-format) which to check against
+* input - `String` - the value written in the [levn format](#levn-format)
+* options - `Maybe Object` - an optional parameter specifying additional [options](#options)
+
+##### returns
+`*` - the resulting JavaScript value
+
+##### example
+```js
+parse('[Number]', '1,2,3'); // [1, 2, 3]
+```
+
+### parsedTypeParse(parsedType, input, options)
+
+`parsedTypeParse` casts the string `input` into a JavaScript value according to the specified `type` which has already been parsed (and taking account the optional `options`) and returns the resulting JavaScript value. You can parse a type using the [type-check](https://github.com/gkz/type-check) library's `parseType` function.
+
+##### arguments
+* type - `Object` - the type in the parsed type format which to check against
+* input - `String` - the value written in the [levn format](#levn-format)
+* options - `Maybe Object` - an optional parameter specifying additional [options](#options)
+
+##### returns
+`*` - the resulting JavaScript value
+
+##### example
+```js
+var parsedType = require('type-check').parseType('[Number]');
+parsedTypeParse(parsedType, '1,2,3'); // [1, 2, 3]
+```
+
+## Levn Format
+
+Levn can use the type information you provide to choose the appropriate value to produce from the input. For the same input, it will choose a different output value depending on the type provided. For example, `parse('Number', '2')` will produce the number `2`, but `parse('String', '2')` will produce the string `"2"`.
+
+If you do not provide type information, and simply use `*`, levn will parse the input according the unambiguous "explicit" mode, which we will now detail - you can also set the `explicit` option to true manually in the [options](#options).
+
+* `"string"`, `'string'` are parsed as a String, eg. `"a msg"` is `"a msg"`
+* `#date#` is parsed as a Date, eg. `#2011-11-11#` is `new Date('2011-11-11')`
+* `/regexp/flags` is parsed as a RegExp, eg. `/re/gi` is `/re/gi`
+* `undefined`, `null`, `NaN`, `true`, and `false` are all their JavaScript equivalents
+* `[element1, element2, etc]` is an Array, and the casting procedure is recursively applied to each element. Eg. `[1,2,3]` is `[1,2,3]`.
+* `(element1, element2, etc)` is an tuple, and the casting procedure is recursively applied to each element. Eg. `(1, a)` is `(1, a)` (is `[1, 'a']`).
+* `{key1: val1, key2: val2, ...}` is an Object, and the casting procedure is recursively applied to each property. Eg. `{a: 1, b: 2}` is `{a: 1, b: 2}`.
+* Any test which does not fall under the above, and which does not contain special characters (`[``]``(``)``{``}``:``,`) is a string, eg. `$12- blah` is `"$12- blah"`.
+
+If you do provide type information, you can make your input more concise as the program already has some information about what it expects. Please see the [type format](https://github.com/gkz/type-check#type-format) section of [type-check](https://github.com/gkz/type-check) for more information about how to specify types. There are some rules about what levn can do with the information:
+
+* If a String is expected, and only a String, all characters of the input (including any special ones) will become part of the output. Eg. `[({})]` is `"[({})]"`, and `"hi"` is `'"hi"'`.
+* If a Date is expected, the surrounding `#` can be omitted from date literals. Eg. `2011-11-11` is `new Date('2011-11-11')`.
+* If a RegExp is expected, no flags need to be specified, and the regex is not using any of the special characters,the opening and closing `/` can be omitted - this will have the affect of setting the source of the regex to the input. Eg. `regex` is `/regex/`.
+* If an Array is expected, and it is the root node (at the top level), the opening `[` and closing `]` can be omitted. Eg. `1,2,3` is `[1,2,3]`.
+* If a tuple is expected, and it is the root node (at the top level), the opening `(` and closing `)` can be omitted. Eg. `1, a` is `(1, a)` (is `[1, 'a']`).
+* If an Object is expected, and it is the root node (at the top level), the opening `{` and closing `}` can be omitted. Eg `a: 1, b: 2` is `{a: 1, b: 2}`.
+
+If you list multiple types (eg. `Number | String`), it will first attempt to cast to the first type and then validate - if the validation fails it will move on to the next type and so forth, left to right. You must be careful as some types will succeed with any input, such as String. Thus put String at the end of your list. In non-explicit mode, Date and RegExp will succeed with a large variety of input - also be careful with these and list them near the end if not last in your list.
+
+Whitespace between special characters and elements is inconsequential.
+
+## Options
+
+Options is an object. It is an optional parameter to the `parse` and `parsedTypeParse` functions.
+
+### Explicit
+
+A `Boolean`. By default it is `false`.
+
+__Example:__
+
+```js
+parse('RegExp', 're', {explicit: false});          // /re/
+parse('RegExp', 're', {explicit: true});           // Error: ... does not type check...
+parse('RegExp | String', 're', {explicit: true});  // 're'
+```
+
+`explicit` sets whether to be in explicit mode or not. Using `*` automatically activates explicit mode. For more information, read the [levn format](#levn-format) section.
+
+### customTypes
+
+An `Object`. Empty `{}` by default.
+
+__Example:__
+
+```js
+var options = {
+  customTypes: {
+    Even: {
+      typeOf: 'Number',
+      validate: function (x) {
+        return x % 2 === 0;
+      },
+      cast: function (x) {
+        return {type: 'Just', value: parseInt(x)};
+      }
+    }
+  }
+}
+parse('Even', '2', options); // 2
+parse('Even', '3', options); // Error: Value: "3" does not type check...
+```
+
+__Another Example:__
+```js
+function Person(name, age){
+  this.name = name;
+  this.age = age;
+}
+var options = {
+  customTypes: {
+    Person: {
+      typeOf: 'Object',
+      validate: function (x) {
+        x instanceof Person;
+      },
+      cast: function (value, options, typesCast) {
+        var name, age;
+        if ({}.toString.call(value).slice(8, -1) !== 'Object') {
+          return {type: 'Nothing'};
+        }
+        name = typesCast(value.name, [{type: 'String'}], options);
+        age = typesCast(value.age, [{type: 'Numger'}], options);
+        return {type: 'Just', value: new Person(name, age)};
+    }
+  }
+}
+parse('Person', '{name: Laura, age: 25}', options); // Person {name: 'Laura', age: 25}
+```
+
+`customTypes` is an object whose keys are the name of the types, and whose values are an object with three properties, `typeOf`, `validate`, and `cast`. For more information about `typeOf` and `validate`, please see the [custom types](https://github.com/gkz/type-check#custom-types) section of type-check.
+
+`cast` is a function which receives three arguments, the value under question, options, and the typesCast function. In `cast`, attempt to cast the value into the specified type. If you are successful, return an object in the format `{type: 'Just', value: CAST-VALUE}`, if you know it won't work, return `{type: 'Nothing'}`.  You can use the `typesCast` function to cast any child values. Remember to pass `options` to it. In your function you can also check for `options.explicit` and act accordingly.
+
+## Technical About
+
+`levn` is written in [LiveScript](http://livescript.net/) - a language that compiles to JavaScript. It uses [type-check](https://github.com/gkz/type-check) to both parse types and validate values. It also uses the [prelude.ls](http://preludels.com/) library.

+# lodash v4.17.4
+
+The [Lodash](https://lodash.com/) library exported as [Node.js](https://nodejs.org/) modules.
+
+## Installation
+
+Using npm:
+```shell
+$ npm i -g npm
+$ npm i --save lodash
+```
+
+In Node.js:
+```js
+// Load the full build.
+var _ = require('lodash');
+// Load the core build.
+var _ = require('lodash/core');
+// Load the FP build for immutable auto-curried iteratee-first data-last methods.
+var fp = require('lodash/fp');
+
+// Load method categories.
+var array = require('lodash/array');
+var object = require('lodash/fp/object');
+
+// Cherry-pick methods for smaller browserify/rollup/webpack bundles.
+var at = require('lodash/at');
+var curryN = require('lodash/fp/curryN');
+```
+
+See the [package source](https://github.com/lodash/lodash/tree/4.17.4-npm) for more details.
+
+**Note:**<br>
+Install [n_](https://www.npmjs.com/package/n_) for Lodash use in the Node.js < 6 REPL.
+
+## Support
+
+Tested in Chrome 54-55, Firefox 49-50, IE 11, Edge 14, Safari 9-10, Node.js 6-7, & PhantomJS 2.1.1.<br>
+Automated [browser](https://saucelabs.com/u/lodash) & [CI](https://travis-ci.org/lodash/lodash/) test runs are available.

+/**
+ * Creates a debounced function that delays invoking `func` until after `wait`
+ * milliseconds have elapsed since the last time the debounced function was
+ * invoked. The debounced function comes with a `cancel` method to cancel
+ * delayed `func` invocations and a `flush` method to immediately invoke them.
+ * Provide `options` to indicate whether `func` should be invoked on the
+ * leading and/or trailing edge of the `wait` timeout. The `func` is invoked
+ * with the last arguments provided to the debounced function. Subsequent
+ * calls to the debounced function return the result of the last `func`
+ * invocation.
+ *
+ * **Note:** If `leading` and `trailing` options are `true`, `func` is
+ * invoked on the trailing edge of the timeout only if the debounced function
+ * is invoked more than once during the `wait` timeout.
+ *
+ * If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
+ * until to the next tick, similar to `setTimeout` with a timeout of `0`.
+ *
+ * See [David Corbacho's article](https://css-tricks.com/debouncing-throttling-explained-examples/)
+ * for details over the differences between `_.debounce` and `_.throttle`.

+     * Creates a `lodash` object which wraps `value` to enable implicit method
+     * chain sequences. Methods that operate on and return arrays, collections,
+     * and functions can be chained together. Methods that retrieve a single value
+     * or may return a primitive value will automatically end the chain sequence
+     * and return the unwrapped value. Otherwise, the value must be unwrapped
+     * with `_#value`.
+     *
+     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
+     * enabled using `_.chain`.
+     *
+     * The execution of chained methods is lazy, that is, it's deferred until
+     * `_#value` is implicitly or explicitly called.
+     *
+     * Lazy evaluation allows several methods to support shortcut fusion.
+     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
+     * the creation of intermediate arrays and can greatly reduce the number of
+     * iteratee executions. Sections of a chain sequence qualify for shortcut
+     * fusion if the section is applied to an array and iteratees accept only
+     * one argument. The heuristic for whether a section qualifies for shortcut
+     * fusion is subject to change.
+     *
+     * Chaining is supported in custom builds as long as the `_#value` method is
+     * directly or indirectly included in the build.

+ * immediately invoke them. Provide `options` to indicate whether `func`

+ * Creates a `lodash` object which wraps `value` to enable implicit method
+ * chain sequences. Methods that operate on and return arrays, collections,
+ * and functions can be chained together. Methods that retrieve a single value
+ * or may return a primitive value will automatically end the chain sequence
+ * and return the unwrapped value. Otherwise, the value must be unwrapped
+ * with `_#value`.
+ *
+ * Explicit chain sequences, which must be unwrapped with `_#value`, may be
+ * enabled using `_.chain`.
+ *
+ * The execution of chained methods is lazy, that is, it's deferred until
+ * `_#value` is implicitly or explicitly called.
+ *
+ * Lazy evaluation allows several methods to support shortcut fusion.
+ * Shortcut fusion is an optimization to merge iteratee calls; this avoids
+ * the creation of intermediate arrays and can greatly reduce the number of
+ * iteratee executions. Sections of a chain sequence qualify for shortcut
+ * fusion if the section is applied to an array and iteratees accept only
+ * one argument. The heuristic for whether a section qualifies for shortcut
+ * fusion is subject to change.
+ *
+ * Chaining is supported in custom builds as long as the `_#value` method is
+ * directly or indirectly included in the build.
+ *
+ * In addition to lodash methods, wrappers have `Array` and `String` methods.
+ *
+ * The wrapper `Array` methods are:
+ * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
+ *
+ * The wrapper `String` methods are:
+ * `replace` and `split`
+ *
+ * The wrapper methods that support shortcut fusion are:
+ * `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
+ * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
+ * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
+ *
+ * The chainable wrapper methods are:
+ * `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
+ * `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,

+
+If you put more stuff in it, then items will fall out.
+
+If you try to put an oversized thing in it, then it'll fall out right
+away.
+
+## Options
+
+* `max` The maximum size of the cache, checked by applying the length
+  function to all values in the cache.  Not setting this is kind of
+  silly, since that's the whole purpose of this lib, but it defaults
+  to `Infinity`.
+* `maxAge` Maximum age in ms.  Items are not pro-actively pruned out
+  as they age, but if you try to get an item that is too old, it'll
+  drop it and return undefined instead of giving it to you.
+* `length` Function that is used to calculate the length of stored
+  items.  If you're storing strings or buffers, then you probably want
+  to do something like `function(n, key){return n.length}`.  The default is
+  `function(){return 1}`, which is fine if you want to store `max`
+  like-sized things.  The item is passed as the first argument, and
+  the key is passed as the second argumnet.
+* `dispose` Function that is called on items when they are dropped
+  from the cache.  This can be handy if you want to close file
+  descriptors or do other cleanup tasks when items are no longer
+  accessible.  Called with `key, value`.  It's called *before*
+  actually removing the item from the internal cache, so if you want
+  to immediately put it back in, you'll have to do that in a
+  `nextTick` or `setTimeout` callback or it won't do anything.
+* `stale` By default, if you set a `maxAge`, it'll only actually pull
+  stale items out of the cache when you `get(key)`.  (That is, it's
+  not pre-emptively doing a `setTimeout` or anything.)  If you set
+  `stale:true`, it'll return the stale value before deleting it.  If
+  you don't set this, then it'll return `undefined` when you try to
+  get a stale entry, as if it had already been deleted.
+* `noDisposeOnSet` By default, if you set a `dispose()` method, then
+  it'll be called whenever a `set()` operation overwrites an existing
+  key.  If you set this option, `dispose()` will only be called when a
+  key falls out of the cache, not when it is overwritten.
+
+## API
+
+* `set(key, value, maxAge)`
+* `get(key) => value`
+
+    Both of these will update the "recently used"-ness of the key.
+    They do what you think. `maxAge` is optional and overrides the
+    cache `maxAge` option if provided.
+
+    If the key is not found, `get()` will return `undefined`.
+
+    The key and val can be any value.
+
+* `peek(key)`
+
+    Returns the key value (or `undefined` if not found) without
+    updating the "recently used"-ness of the key.
+
+    (If you find yourself using this a lot, you *might* be using the
+    wrong sort of data structure, but there are some use cases where
+    it's handy.)
+
+* `del(key)`
+
+    Deletes a key out of the cache.
+
+* `reset()`
+
+    Clear the cache entirely, throwing away all values.
+
+* `has(key)`
+
+    Check if a key is in the cache, without updating the recent-ness
+    or deleting it for being stale.
+
+* `forEach(function(value,key,cache), [thisp])`
+
+    Just like `Array.prototype.forEach`.  Iterates over all the keys
+    in the cache, in order of recent-ness.  (Ie, more recently used
+    items are iterated over first.)
+
+* `rforEach(function(value,key,cache), [thisp])`
+
+    The same as `cache.forEach(...)` but items are iterated over in
+    reverse order.  (ie, less recently used items are iterated over
+    first.)
+
+* `keys()`
+
+    Return an array of the keys in the cache.
+
+* `values()`
+
+    Return an array of the values in the cache.
+
+* `length`
+
+    Return total length of objects in cache taking into account
+    `length` options function.
+
+* `itemCount`
+
+    Return total quantity of objects currently in cache. Note, that
+    `stale` (see options) items are returned as part of this item
+    count.
+
+* `dump()`
+
+    Return an array of the cache entries ready for serialization and usage
+    with 'destinationCache.load(arr)`.
+
+* `load(cacheEntriesArray)`
+
+    Loads another cache entries array, obtained with `sourceCache.dump()`,
+    into the cache. The destination cache is reset before loading new entries
+
+* `prune()`
+
+    Manually iterates over the entire cache proactively pruning old entries

+# minimatch
+
+A minimal matching utility.
+
+[![Build Status](https://secure.travis-ci.org/isaacs/minimatch.svg)](http://travis-ci.org/isaacs/minimatch)
+
+
+This is the matching library used internally by npm.
+
+It works by converting glob expressions into JavaScript `RegExp`
+objects.
+
+## Usage
+
+```javascript
+var minimatch = require("minimatch")
+
+minimatch("bar.foo", "*.foo") // true!
+minimatch("bar.foo", "*.bar") // false!
+minimatch("bar.foo", "*.+(bar|foo)", { debug: true }) // true, and noisy!
+```
+
+## Features
+
+Supports these glob features:
+
+* Brace Expansion
+* Extended glob matching
+* "Globstar" `**` matching
+
+See:
+
+* `man sh`
+* `man bash`
+* `man 3 fnmatch`
+* `man 5 gitignore`
+
+## Minimatch Class
+
+Create a minimatch object by instantiating the `minimatch.Minimatch` class.
+
+```javascript
+var Minimatch = require("minimatch").Minimatch
+var mm = new Minimatch(pattern, options)
+```
+
+### Properties
+
+* `pattern` The original pattern the minimatch object represents.
+* `options` The options supplied to the constructor.
+* `set` A 2-dimensional array of regexp or string expressions.
+  Each row in the
+  array corresponds to a brace-expanded pattern.  Each item in the row
+  corresponds to a single path-part.  For example, the pattern
+  `{a,b/c}/d` would expand to a set of patterns like:
+
+        [ [ a, d ]
+        , [ b, c, d ] ]
+
+    If a portion of the pattern doesn't have any "magic" in it
+    (that is, it's something like `"foo"` rather than `fo*o?`), then it
+    will be left as a string rather than converted to a regular
+    expression.
+
+* `regexp` Created by the `makeRe` method.  A single regular expression
+  expressing the entire pattern.  This is useful in cases where you wish
+  to use the pattern somewhat like `fnmatch(3)` with `FNM_PATH` enabled.
+* `negate` True if the pattern is negated.
+* `comment` True if the pattern is a comment.
+* `empty` True if the pattern is `""`.
+
+### Methods
+
+* `makeRe` Generate the `regexp` member if necessary, and return it.
+  Will return `false` if the pattern is invalid.
+* `match(fname)` Return true if the filename matches the pattern, or
+  false otherwise.
+* `matchOne(fileArray, patternArray, partial)` Take a `/`-split
+  filename, and match it against a single row in the `regExpSet`.  This
+  method is mainly for internal use, but is exposed so that it can be
+  used by a glob-walker that needs to avoid excessive filesystem calls.
+
+All other methods are internal, and will be called as necessary.
+
+### minimatch(path, pattern, options)
+
+Main export.  Tests a path against the pattern using the options.
+
+```javascript
+var isJS = minimatch(file, "*.js", { matchBase: true })
+```
+
+### minimatch.filter(pattern, options)
+
+Returns a function that tests its
+supplied argument, suitable for use with `Array.filter`.  Example:
+
+```javascript
+var javascripts = fileList.filter(minimatch.filter("*.js", {matchBase: true}))
+```
+
+### minimatch.match(list, pattern, options)
+
+Match against the list of
+files, in the style of fnmatch or glob.  If nothing is matched, and
+options.nonull is set, then return a list containing the pattern itself.
+
+```javascript
+var javascripts = minimatch.match(fileList, "*.js", {matchBase: true}))
+```
+
+### minimatch.makeRe(pattern, options)
+
+Make a regular expression object from the pattern.
+
+## Options
+
+All options are `false` by default.
+
+### debug
+
+Dump a ton of stuff to stderr.
+
+### nobrace
+
+Do not expand `{a,b}` and `{1..3}` brace sets.
+
+### noglobstar
+
+Disable `**` matching against multiple folder names.
+
+### dot
+
+Allow patterns to match filenames starting with a period, even if
+the pattern does not explicitly have a period in that spot.
+
+Note that by default, `a/**/b` will **not** match `a/.d/b`, unless `dot`
+is set.
+
+### noext
+
+Disable "extglob" style patterns like `+(a|b)`.
+
+### nocase
+
+Perform a case-insensitive match.
+
+### nonull
+
+When a match is not found by `minimatch.match`, return a list containing
+the pattern itself if this option is set.  When not set, an empty list
+is returned if there are no matches.
+
+### matchBase
+
+If set, then patterns without slashes will be matched
+against the basename of the path if it contains slashes.  For example,
+`a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`.
+
+### nocomment
+
+Suppress the behavior of treating `#` at the start of a pattern as a
+comment.
+
+### nonegate
+
+Suppress the behavior of treating a leading `!` character as negation.
+
+### flipNegate
+
+Returns from negate expressions the same as if they were not negated.
+(Ie, true on a hit, false on a miss.)
+
+
+## Comparisons to other fnmatch/glob implementations
+
+While strict compliance with the existing standards is a worthwhile
+goal, some discrepancies exist between minimatch and other
+implementations, and are intentional.
+
+If the pattern starts with a `!` character, then it is negated.  Set the
+`nonegate` flag to suppress this behavior, and treat leading `!`
+characters normally.  This is perhaps relevant if you wish to start the
+pattern with a negative extglob pattern like `!(a|B)`.  Multiple `!`
+characters at the start of a pattern will negate the pattern multiple
+times.
+
+If a pattern starts with `#`, then it is treated as a comment, and
+will not match anything.  Use `\#` to match a literal `#` at the
+start of a line, or set the `nocomment` flag to suppress this behavior.
+
+The double-star character `**` is supported by default, unless the
+`noglobstar` flag is set.  This is supported in the manner of bsdglob
+and bash 4.1, where `**` only has special significance if it is the only
+thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
+`a/**b` will not.
+
+If an escaped pattern has no matches, and the `nonull` flag is set,
+then minimatch.match returns the pattern as-provided, rather than
+interpreting the character escapes.  For example,
+`minimatch.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
+`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
+that it does not resolve escaped pattern characters.
+
+If brace expansion is not disabled, then it is performed before any
+other interpretation of the glob pattern.  Thus, a pattern like
+`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
+**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
+checked for validity.  Since those two are valid, matching proceeds.

+# minimist
+
+parse argument options
+
+This module is the guts of optimist's argument parser without all the
+fanciful decoration.
+
+[![browser support](https://ci.testling.com/substack/minimist.png)](http://ci.testling.com/substack/minimist)
+
+[![build status](https://secure.travis-ci.org/substack/minimist.png)](http://travis-ci.org/substack/minimist)
+
+# example
+
+``` js
+var argv = require('minimist')(process.argv.slice(2));
+console.dir(argv);
+```
+
+```
+$ node example/parse.js -a beep -b boop
+{ _: [], a: 'beep', b: 'boop' }
+```
+
+```
+$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
+{ _: [ 'foo', 'bar', 'baz' ],
+  x: 3,
+  y: 4,
+  n: 5,
+  a: true,
+  b: true,
+  c: true,
+  beep: 'boop' }
+```
+
+# methods
+
+``` js
+var parseArgs = require('minimist')
+```
+
+## var argv = parseArgs(args, opts={})
+
+Return an argument object `argv` populated with the array arguments from `args`.
+
+`argv._` contains all the arguments that didn't have an option associated with
+them.
+
+Numeric-looking arguments will be returned as numbers unless `opts.string` or
+`opts.boolean` is set for that argument name.
+
+Any arguments after `'--'` will not be parsed and will end up in `argv._`.
+
+options can be:
+
+* `opts.string` - a string or array of strings argument names to always treat as
+strings
+* `opts.boolean` - a string or array of strings to always treat as booleans
+* `opts.alias` - an object mapping string names to strings or arrays of string
+argument names to use as aliases
+* `opts.default` - an object mapping string argument names to default values

+# mkdirp
+
+Like `mkdir -p`, but in node.js!
+
+[![build status](https://secure.travis-ci.org/substack/node-mkdirp.png)](http://travis-ci.org/substack/node-mkdirp)
+
+# example
+
+## pow.js
+
+```js
+var mkdirp = require('mkdirp');
+    
+mkdirp('/tmp/foo/bar/baz', function (err) {
+    if (err) console.error(err)
+    else console.log('pow!')
+});
+```
+
+Output
+
+```
+pow!
+```
+
+And now /tmp/foo/bar/baz exists, huzzah!
+
+# methods
+
+```js
+var mkdirp = require('mkdirp');
+```
+
+## mkdirp(dir, opts, cb)
+
+Create a new directory and any necessary subdirectories at `dir` with octal
+permission string `opts.mode`. If `opts` is a non-object, it will be treated as
+the `opts.mode`.
+
+If `opts.mode` isn't specified, it defaults to `0777 & (~process.umask())`.
+
+`cb(err, made)` fires with the error or the first directory `made`
+that had to be created, if any.
+
+You can optionally pass in an alternate `fs` implementation by passing in
+`opts.fs`. Your implementation should have `opts.fs.mkdir(path, mode, cb)` and
+`opts.fs.stat(path, cb)`.
+
+## mkdirp.sync(dir, opts)
+
+Synchronously create a new directory and any necessary subdirectories at `dir`
+with octal permission string `opts.mode`. If `opts` is a non-object, it will be
+treated as the `opts.mode`.
+
+If `opts.mode` isn't specified, it defaults to `0777 & (~process.umask())`.
+
+Returns the first directory that had to be created, if any.
+
+You can optionally pass in an alternate `fs` implementation by passing in
+`opts.fs`. Your implementation should have `opts.fs.mkdirSync(path, mode)` and
+`opts.fs.statSync(path)`.
+
+# usage
+
+This package also ships with a `mkdirp` command.
+
+```
+usage: mkdirp [DIR1,DIR2..] {OPTIONS}
+
+  Create each supplied directory including any necessary parent directories that
+  don't yet exist.
+  
+  If the directory already exists, do nothing.
+
+OPTIONS are:
+
+  -m, --mode   If a directory needs to be created, set the mode as an octal
+               permission string.
+
+```
+
+# install
+
+With [npm](http://npmjs.org) do:
+
+```
+npm install mkdirp
+```
+
+to get the library, or
+
+```
+npm install -g mkdirp
+```
+
+to get the command.

+# ms
+
+[![Build Status](https://travis-ci.org/zeit/ms.svg?branch=master)](https://travis-ci.org/zeit/ms)
+[![Slack Channel](http://zeit-slackin.now.sh/badge.svg)](https://zeit.chat/)
+
+Use this package to easily convert various time formats to milliseconds.
+
+## Examples
+
+```js
+ms('2 days')  // 172800000
+ms('1d')      // 86400000
+ms('10h')     // 36000000
+ms('2.5 hrs') // 9000000
+ms('2h')      // 7200000
+ms('1m')      // 60000
+ms('5s')      // 5000
+ms('1y')      // 31557600000
+ms('100')     // 100
+```
+
+### Convert from milliseconds
+
+```js
+ms(60000)             // "1m"
+ms(2 * 60000)         // "2m"
+ms(ms('10 hours'))    // "10h"
+```
+
+### Time format written-out
+
+```js
+ms(60000, { long: true })             // "1 minute"
+ms(2 * 60000, { long: true })         // "2 minutes"
+ms(ms('10 hours'), { long: true })    // "10 hours"
+```
+
+## Features
+
+- Works both in [node](https://nodejs.org) and in the browser.
+- If a number is supplied to `ms`, a string with a unit is returned.
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`).
+- If you pass a string with a number and a valid unit, the number of equivalent ms is returned.
+
+## Caught a bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, node will now use your clone of ms!

+# mute-stream
+
+Bytes go in, but they don't come out (when muted).
+
+This is a basic pass-through stream, but when muted, the bytes are
+silently dropped, rather than being passed through.
+
+## Usage
+
+```javascript
+var MuteStream = require('mute-stream')
+
+var ms = new MuteStream(options)
+
+ms.pipe(process.stdout)
+ms.write('foo') // writes 'foo' to stdout
+ms.mute()
+ms.write('bar') // does not write 'bar'
+ms.unmute()
+ms.write('baz') // writes 'baz' to stdout
+
+// can also be used to mute incoming data
+var ms = new MuteStream
+input.pipe(ms)
+
+ms.on('data', function (c) {
+  console.log('data: ' + c)
+})
+
+input.emit('data', 'foo') // logs 'foo'
+ms.mute()
+input.emit('data', 'bar') // does not log 'bar'
+ms.unmute()
+input.emit('data', 'baz') // logs 'baz'
+```
+
+## Options
+
+All options are optional.
+
+* `replace` Set to a string to replace each character with the
+  specified string when muted.  (So you can show `****` instead of the
+  password, for example.)
+
+* `prompt` If you are using a replacement char, and also using a
+  prompt with a readline stream (as for a `Password: *****` input),
+  then specify what the prompt is so that backspace will work
+  properly.  Otherwise, pressing backspace will overwrite the prompt
+  with the replacement character, which is weird.
+
+## ms.mute()
+
+Set `muted` to `true`.  Turns `.write()` into a no-op.
+
+## ms.unmute()
+
+Set `muted` to `false`
+
+## ms.isTTY
+
+True if the pipe destination is a TTY, or if the incoming pipe source is
+a TTY.
+
+## Other stream methods...
+
+The other standard readable and writable stream methods are all
+available.  The MuteStream object acts as a facade to its pipe source
+and destination.

+Natural Compare &ndash; [![Build][]][1] [![Coverage][]][2]
+===============
+
+Compare strings containing a mix of letters and numbers
+in the way a human being would in sort order.
+This is described as a "natural ordering".
+
+```text
+Standard sorting:   Natural order sorting:
+    img1.png            img1.png
+    img10.png           img2.png
+    img12.png           img10.png
+    img2.png            img12.png
+```
+
+String.naturalCompare returns a number indicating
+whether a reference string comes before or after or is the same
+as the given string in sort order.
+Use it with builtin sort() function.
+
+
+
+### Installation
+
+- In browser
+
+```html
+<script src=min.natural-compare.js></script>
+```
+
+- In node.js: `npm install natural-compare-lite`
+
+```javascript
+require("natural-compare-lite")
+```
+
+### Usage
+
+```javascript
+// Simple case sensitive example
+var a = ["z1.doc", "z10.doc", "z17.doc", "z2.doc", "z23.doc", "z3.doc"];
+a.sort(String.naturalCompare);
+// ["z1.doc", "z2.doc", "z3.doc", "z10.doc", "z17.doc", "z23.doc"]
+
+// Use wrapper function for case insensitivity
+a.sort(function(a, b){
+  return String.naturalCompare(a.toLowerCase(), b.toLowerCase());
+})
+
+// In most cases we want to sort an array of objects
+var a = [ {"street":"350 5th Ave", "room":"A-1021"}
+        , {"street":"350 5th Ave", "room":"A-21046-b"} ];
+
+// sort by street, then by room
+a.sort(function(a, b){
+  return String.naturalCompare(a.street, b.street) || String.naturalCompare(a.room, b.room);
+})
+
+// When text transformation is needed (eg toLowerCase()),
+// it is best for performance to keep
+// transformed key in that object.
+// There are no need to do text transformation
+// on each comparision when sorting.
+var a = [ {"make":"Audi", "model":"A6"}
+        , {"make":"Kia",  "model":"Rio"} ];
+
+// sort by make, then by model
+a.map(function(car){
+  car.sort_key = (car.make + " " + car.model).toLowerCase();
+})
+a.sort(function(a, b){
+  return String.naturalCompare(a.sort_key, b.sort_key);
+})
+```
+
+- Works well with dates in ISO format eg "Rev 2012-07-26.doc".
+
+
+### Custom alphabet
+
+It is possible to configure a custom alphabet
+to achieve a desired order.
+
+```javascript
+// Estonian alphabet
+String.alphabet = "ABDEFGHIJKLMNOPRSŠZŽTUVÕÄÖÜXYabdefghijklmnoprsšzžtuvõäöüxy"
+["t", "z", "x", "õ"].sort(String.naturalCompare)
+// ["z", "t", "õ", "x"]
+
+// Russian alphabet
+String.alphabet = "АБВГДЕЁЖЗИЙКЛМНОПРСТУФХЦЧШЩЪЫЬЭЮЯабвгдеёжзийклмнопрстуфхцчшщъыьэюя"
+["Ё", "А", "Б"].sort(String.naturalCompare)
+// ["А", "Б", "Ё"]
+```

+# object-assign [![Build Status](https://travis-ci.org/sindresorhus/object-assign.svg?branch=master)](https://travis-ci.org/sindresorhus/object-assign)
+
+> ES2015 [`Object.assign()`](http://www.2ality.com/2014/01/object-assign.html) [ponyfill](https://ponyfill.com)
+
+
+## Use the built-in
+
+Node.js 4 and up, as well as every evergreen browser (Chrome, Edge, Firefox, Opera, Safari),
+support `Object.assign()` :tada:. If you target only those environments, then by all
+means, use `Object.assign()` instead of this package.
+
+
+## Install
+
+```
+$ npm install --save object-assign
+```
+
+
+## Usage
+
+```js
+const objectAssign = require('object-assign');
+
+objectAssign({foo: 0}, {bar: 1});
+//=> {foo: 0, bar: 1}
+
+// multiple sources
+objectAssign({foo: 0}, {bar: 1}, {baz: 2});
+//=> {foo: 0, bar: 1, baz: 2}
+
+// overwrites equal keys
+objectAssign({foo: 0}, {foo: 1}, {foo: 2});
+//=> {foo: 2}
+
+// ignores null and undefined sources
+objectAssign({foo: 0}, null, {bar: 1}, undefined);
+//=> {foo: 0, bar: 1}
+```
+
+
+## API
+
+### objectAssign(target, [source, ...])
+
+Assigns enumerable own properties of `source` objects to the `target` object and returns the `target` object. Additional `source` objects will overwrite previous ones.
+

+# once
+
+Only call a function once.
+
+## usage
+
+```javascript
+var once = require('once')
+
+function load (file, cb) {
+  cb = once(cb)
+  loader.load('file')
+  loader.once('load', cb)
+  loader.once('error', cb)
+}
+```
+
+Or add to the Function.prototype in a responsible way:
+
+```javascript
+// only has to be done once
+require('once').proto()
+
+function load (file, cb) {
+  cb = cb.once()
+  loader.load('file')
+  loader.once('load', cb)
+  loader.once('error', cb)
+}
+```
+
+Ironically, the prototype feature makes this module twice as
+complicated as necessary.
+
+To check whether you function has been called, use `fn.called`. Once the
+function is called for the first time the return value of the original
+function is saved in `fn.value` and subsequent calls will continue to
+return this value.
+
+```javascript
+var once = require('once')
+
+function load (cb) {
+  cb = once(cb)
+  var stream = createStream()
+  stream.once('data', cb)
+  stream.once('end', function () {
+    if (!cb.called) cb(new Error('not found'))
+  })
+}
+```
+
+## `once.strict(func)`
+
+Throw an error if the function is called twice.
+
+Some functions are expected to be called only once. Using `once` for them would
+potentially hide logical errors.
+
+In the example below, the `greet` function has to call the callback only once:
+
+```javascript
+function greet (name, cb) {
+  // return is missing from the if statement
+  // when no name is passed, the callback is called twice
+  if (!name) cb('Hello anonymous')
+  cb('Hello ' + name)
+}
+
+function log (msg) {
+  console.log(msg)
+}
+
+// this will print 'Hello anonymous' but the logical error will be missed
+greet(null, once(msg))
+
+// once.strict will print 'Hello anonymous' and throw an error when the callback will be called the second time
+greet(null, once.strict(msg))
+```

+
+## Install

+
+## Usage
+
+```js
+let i = 0;

+const foo = onetime(() => i++);
+
+foo(); //=> 0
+foo(); //=> 0
+foo(); //=> 0
+```

+foo();
+
+foo();
+//=> Error: Function `foo` can only be called once
+```
+
+
+## API
+
+### onetime(fn, [options])
+
+Returns a function that only calls `fn` once.
+
+#### fn
+
+Type: `Function`
+
+Function that should only be called once.
+
+#### options
+
+Type: `Object`
+
+##### throw
+
+Type: `boolean`<br>
+Default: `false`
+
+Throw an error when called more than once.

+# Optionator
+<a name="optionator" />
+
+Optionator is a JavaScript option parsing and help generation library used by [eslint](http://eslint.org), [Grasp](http://graspjs.com), [LiveScript](http://livescript.net), [esmangle](https://github.com/estools/esmangle), [escodegen](https://github.com/estools/escodegen), and [many more](https://www.npmjs.com/browse/depended/optionator).
+
+For an online demo, check out the [Grasp online demo](http://www.graspjs.com/#demo).
+
+[About](#about) &middot; [Usage](#usage) &middot; [Settings Format](#settings-format) &middot; [Argument Format](#argument-format)
+
+## Why?
+The  problem with other option parsers, such as `yargs` or `minimist`, is they just accept all input, valid or not.
+With Optionator, if you mistype an option, it will give you an error (with a suggestion for what you meant).
+If you give the wrong type of argument for an option, it will give you an error rather than supplying the wrong input to your application.
+
+    $ cmd --halp
+    Invalid option '--halp' - perhaps you meant '--help'?
+
+    $ cmd --count str
+    Invalid value for option 'count' - expected type Int, received value: str.
+
+Other helpful features include reformatting the help text based on the size of the console, so that it fits even if the console is narrow, and accepting not just an array (eg. process.argv), but a string or object as well, making things like testing much easier.

+
+## Usage
+`require('optionator');` returns a function. It has one property, `VERSION`, the current version of the library as a string. This function is called with an object specifying your options and other information, see the [settings format section](#settings-format). This in turn returns an object with three properties, `parse`, `parseArgv`, `generateHelp`, and `generateHelpForOption`, which are all functions.
+
+```js
+var optionator = require('optionator')({
+    prepend: 'Usage: cmd [options]',
+    append: 'Version 1.0.0',
+    options: [{
+        option: 'help',
+        alias: 'h',
+        type: 'Boolean',
+        description: 'displays help'
+    }, {
+        option: 'count',
+        alias: 'c',
+        type: 'Int',
+        description: 'number of things',
+        example: 'cmd --count 2'
+    }]
+});
+
+var options = optionator.parseArgv(process.argv);
+if (options.help) {
+    console.log(optionator.generateHelp());
+}
+...
+```
+
+### parse(input, parseOptions)
+`parse` processes the `input` according to your settings, and returns an object with the results.
+
+##### arguments
+* input - `[String] | Object | String` - the input you wish to parse
+* parseOptions - `{slice: Int}` - all options optional
+    - `slice` specifies how much to slice away from the beginning if the input is an array or string - by default `0` for string, `2` for array (works with `process.argv`)
+
+##### returns
+`Object` - the parsed options, each key is a camelCase version of the option name (specified in dash-case), and each value is the processed value for that option. Positional values are in an array under the `_` key.
+
+##### example
+```js
+parse(['node', 't.js', '--count', '2', 'positional']); // {count: 2, _: ['positional']}
+parse('--count 2 positional');                         // {count: 2, _: ['positional']}
+parse({count: 2, _:['positional']});                   // {count: 2, _: ['positional']}
+```
+
+### parseArgv(input)
+`parseArgv` works exactly like `parse`, but only for array input and it slices off the first two elements.
+
+##### arguments
+* input - `[String]` - the input you wish to parse
+
+##### returns
+See "returns" section in "parse"
+
+##### example
+```js
+parseArgv(process.argv);
+```
+
+### generateHelp(helpOptions)
+`generateHelp` produces help text based on your settings.
+
+##### arguments
+* helpOptions - `{showHidden: Boolean, interpolate: Object}` - all options optional
+    - `showHidden` specifies whether to show options with `hidden: true` specified, by default it is `false`
+    - `interpolate` specify data to be interpolated in `prepend` and `append` text, `{{key}}` is the format - eg. `generateHelp({interpolate:{version: '0.4.2'}})`, will change this `append` text: `Version {{version}}` to `Version 0.4.2`
+
+##### returns
+`String` - the generated help text
+
+##### example
+```js
+generateHelp(); /*
+"Usage: cmd [options] positional
+
+  -h, --help       displays help
+  -c, --count Int  number of things
+
+Version  1.0.0
+"*/
+```
+
+### generateHelpForOption(optionName)
+`generateHelpForOption` produces expanded help text for the specified with `optionName` option. If an `example` was specified for the option, it will be displayed,  and if a `longDescription` was specified, it will display that instead of the `description`.
+
+##### arguments
+* optionName - `String` - the name of the option to display
+
+##### returns
+`String` - the generated help text for the option
+
+##### example
+```js
+generateHelpForOption('count'); /*
+"-c, --count Int
+description: number of things
+example: cmd --count 2
+"*/
+```
+
+## Settings Format
+When your `require('optionator')`, you get a function that takes in a settings object. This object has the type:
+
+    {
+      prepend: String,
+      append: String,
+      options: [{heading: String} | {
+        option: String,
+        alias: [String] | String,
+        type: String,
+        enum: [String],
+        default: String,
+        restPositional: Boolean,
+        required: Boolean,
+        overrideRequired: Boolean,
+        dependsOn: [String] | String,
+        concatRepeatedArrays: Boolean | (Boolean, Object),
+        mergeRepeatedObjects: Boolean,
+        description: String,
+        longDescription: String,
+        example: [String] | String
+      }],
+      helpStyle: {
+        aliasSeparator: String,
+        typeSeparator: String,
+        descriptionSeparator: String,
+        initialIndent: Int,
+        secondaryIndent: Int,
+        maxPadFactor: Number
+      },
+      mutuallyExclusive: [[String | [String]]],
+      concatRepeatedArrays: Boolean | (Boolean, Object), // deprecated, set in defaults object
+      mergeRepeatedObjects: Boolean, // deprecated, set in defaults object
+      positionalAnywhere: Boolean,
+      typeAliases: Object,
+      defaults: Object
+    }
+
+All of the properties are optional (the `Maybe` has been excluded for brevities sake), except for having either `heading: String` or `option: String` in each object in the `options` array.
+
+### Top Level Properties
+* `prepend` is an optional string to be placed before the options in the help text
+* `append` is an optional string to be placed after the options in the help text
+* `options` is a required array specifying your options and headings, the options and headings will be displayed in the order specified
+* `helpStyle` is an optional object which enables you to change the default appearance of some aspects of the help text
+* `mutuallyExclusive` is an optional array of arrays of either strings or arrays of strings. The top level array is a list of rules, each rule is a list of elements - each element can be either a string (the name of an option), or a list of strings (a group of option names) - there will be an error if more than one element is present
+* `concatRepeatedArrays` see description under the "Option Properties" heading - use at the top level is deprecated, if you want to set this for all options, use the `defaults` property
+* `mergeRepeatedObjects` see description under the "Option Properties" heading - use at the top level is deprecated, if you want to set this for all options, use the `defaults` property
+* `positionalAnywhere` is an optional boolean (defaults to `true`) - when `true` it allows positional arguments anywhere, when `false`, all arguments after the first positional one are taken to be positional as well, even if they look like a flag. For example, with `positionalAnywhere: false`, the arguments `--flag --boom 12 --crack` would have two positional arguments: `12` and `--crack`
+* `typeAliases` is an optional object, it allows you to set aliases for types, eg. `{Path: 'String'}` would allow you to use the type `Path` as an alias for the type `String`
+* `defaults` is an optional object following the option properties format, which specifies default values for all options. A default will be overridden if manually set. For example, you can do `default: { type: "String" }` to set the default type of all options to `String`, and then override that default in an individual option by setting the `type` property
+
+#### Heading Properties
+* `heading` a required string, the name of the heading
+
+#### Option Properties
+* `option` the required name of the option - use dash-case, without the leading dashes
+* `alias` is an optional string or array of strings which specify any aliases for the option
+* `type` is a required string in the [type check](https://github.com/gkz/type-check) [format](https://github.com/gkz/type-check#type-format), this will be used to cast the inputted value and validate it
+* `enum` is an optional array of strings, each string will be parsed by [levn](https://github.com/gkz/levn) - the argument value must be one of the resulting values - each potential value must validate against the specified `type`
+* `default` is a optional string, which will be parsed by [levn](https://github.com/gkz/levn) and used as the default value if none is set - the value must validate against the specified `type`
+* `restPositional` is an optional boolean - if set to `true`, everything after the option will be taken to be a positional argument, even if it looks like a named argument
+* `required` is an optional boolean - if set to `true`, the option parsing will fail if the option is not defined
+* `overrideRequired` is a optional boolean - if set to `true` and the option is used, and there is another option which is required but not set, it will override the need for the required option and there will be no error - this is useful if you have required options and want to use `--help` or `--version` flags
+* `concatRepeatedArrays` is an optional boolean or tuple with boolean and options object (defaults to `false`) - when set to `true` and an option contains an array value and is repeated, the subsequent values for the flag will be appended rather than overwriting the original value - eg. option `g` of type `[String]`: `-g a -g b -g c,d` will result in `['a','b','c','d']`
+
+ You can supply an options object by giving the following value: `[true, options]`. The one currently supported option is `oneValuePerFlag`, this only allows one array value per flag. This is useful if your potential values contain a comma.
+* `mergeRepeatedObjects` is an optional boolean (defaults to `false`) - when set to `true` and an option contains an object value and is repeated, the subsequent values for the flag will be merged rather than overwriting the original value - eg. option `g` of type `Object`: `-g a:1 -g b:2 -g c:3,d:4` will result in `{a: 1, b: 2, c: 3, d: 4}`
+* `dependsOn` is an optional string or array of strings - if simply a string (the name of another option), it will make sure that that other option is set, if an array of strings, depending on whether `'and'` or `'or'` is first, it will either check whether all (`['and', 'option-a', 'option-b']`), or at least one (`['or', 'option-a', 'option-b']`) other options are set
+* `description` is an optional string, which will be displayed next to the option in the help text
+* `longDescription` is an optional string, it will be displayed instead of the `description` when `generateHelpForOption` is used
+* `example` is an optional string or array of strings with example(s) for the option - these will be displayed when `generateHelpForOption` is used
+
+#### Help Style Properties
+* `aliasSeparator` is an optional string, separates multiple names from each other - default: ' ,'
+* `typeSeparator` is an optional string, separates the type from the names - default: ' '
+* `descriptionSeparator` is an optional string , separates the description from the padded name and type - default: '  '
+* `initialIndent` is an optional int - the amount of indent for options - default: 2
+* `secondaryIndent` is an optional int - the amount of indent if wrapped fully (in addition to the initial indent) - default: 4
+* `maxPadFactor` is an optional number - affects the default level of padding for the names/type, it is multiplied by the average of the length of the names/type - default: 1.5
+
+## Argument Format
+At the highest level there are two types of arguments: named, and positional.
+
+Name arguments of any length are prefixed with `--` (eg. `--go`), and those of one character may be prefixed with either `--` or `-` (eg. `-g`).
+
+There are two types of named arguments: boolean flags (eg. `--problemo`, `-p`) which take no value and result in a `true` if they are present, the falsey `undefined` if they are not present, or `false` if present and explicitly prefixed with `no` (eg. `--no-problemo`). Named arguments with values (eg. `--tseries 800`, `-t 800`) are the other type. If the option has a type `Boolean` it will automatically be made into a boolean flag. Any other type results in a named argument that takes a value.
+
+For more information about how to properly set types to get the value you want, take a look at the [type check](https://github.com/gkz/type-check) and [levn](https://github.com/gkz/levn) pages.
+
+You can group single character arguments that use a single `-`, however all except the last must be boolean flags (which take no value). The last may be a boolean flag, or an argument which takes a value - eg. `-ba 2` is equivalent to `-b -a 2`.
+
+Positional arguments are all those values which do not fall under the above - they can be anywhere, not just at the end. For example, in `cmd -b one -a 2 two` where `b` is a boolean flag, and `a` has the type `Number`, there are two positional arguments, `one` and `two`.
+
+Everything after an `--` is positional, even if it looks like a named argument.
+
+You may optionally use `=` to separate option names from values, for example: `--count=2`.
+
+If you specify the option `NUM`, then any argument using a single `-` followed by a number will be valid and will set the value of `NUM`. Eg. `-2` will be parsed into `NUM: 2`.
+
+If duplicate named arguments are present, the last one will be taken.
+
+## Technical About
+`optionator` is written in [LiveScript](http://livescript.net/) - a language that compiles to JavaScript. It uses [levn](https://github.com/gkz/levn) to cast arguments to their specified type, and uses [type-check](https://github.com/gkz/type-check) to validate values. It also uses the [prelude.ls](http://preludels.com/) library.

+# os-tmpdir [![Build Status](https://travis-ci.org/sindresorhus/os-tmpdir.svg?branch=master)](https://travis-ci.org/sindresorhus/os-tmpdir)
+
+> Node.js [`os.tmpdir()`](https://nodejs.org/api/os.html#os_os_tmpdir) [ponyfill](https://ponyfill.com)
+
+Use this instead of `require('os').tmpdir()` to get a consistent behavior on different Node.js versions (even 0.8).
+
+
+## Install
+
+```
+$ npm install --save os-tmpdir
+```
+
+
+## Usage
+
+```js
+const osTmpdir = require('os-tmpdir');
+
+osTmpdir();
+//=> '/var/folders/m3/5574nnhn0yj488ccryqr7tc80000gn/T'
+```
+
+
+## API
+
+See the [`os.tmpdir()` docs](https://nodejs.org/api/os.html#os_os_tmpdir).

+# parse-entities [![Build Status][build-badge]][build-status] [![Coverage Status][coverage-badge]][coverage-status]
+
+Parse HTML character references: fast, spec-compliant, positional
+information.
+
+## Installation
+
+[npm][]:
+
+```bash
+npm install parse-entities
+```
+
+## Usage
+
+```js
+var decode = require('parse-entities');
+
+decode('alpha &amp bravo');
+//=> alpha & bravo
+
+decode('charlie &copycat; delta');
+//=> charlie ©cat; delta
+
+decode('echo &copy; foxtrot &#8800; golf &#x1D306; hotel');
+//=> echo © foxtrot ≠ golf 𝌆 hotel
+```
+
+## API
+
+## `parseEntities(value[, options])`
+
+###### `options`
+
+*   `additional` (`string`, optional, default: `''`)
+    — Additional character to accept when following an ampersand (without
+    error)
+*   `attribute` (`boolean`, optional, default: `false`)
+    — Whether to parse `value` as an attribute value
+*   `nonTerminated` (`boolean`, default: `true`)
+    — Whether to allow non-terminated entities, such as `&copycat` to
+    `©cat`.  This behaviour is spec-compliant but can lead to unexpected
+    results
+*   `warning` ([`Function`][warning], optional)
+    — Error handler
+*   `text` ([`Function`][text], optional)
+    — Text handler
+*   `reference` ([`Function`][reference],
+    optional) — Reference handler
+*   `warningContext` (`'*'`, optional)
+    — Context used when invoking `warning`
+*   `textContext` (`'*'`, optional)
+    — Context used when invoking `text`
+*   `referenceContext` (`'*'`, optional)
+    — Context used when invoking `reference`
+*   `position` (`Location` or `Position`, optional)
+    — Starting `position` of `value`, useful when dealing with values
+    nested in some sort of syntax tree.  The default is:
+
+    ```json
+    {
+      "start": {
+        "line": 1,
+        "column": 1,
+        "offset": 0
+      },
+      "indent": []
+    }
+    ```
+
+###### Returns
+
+`string` — Decoded `value`.
+
+### `function warning(reason, position, code)`
+
+Error handler.
+
+###### Context
+
+`this` refers to `warningContext` when given to `parseEntities`.
+
+###### Parameters
+
+*   `reason` (`string`)
+    — Reason (human-readable) for triggering a parse error
+*   `position` (`Position`)
+    — Place at which the parse error occurred
+*   `code` (`number`)

+# pify [![Build Status](https://travis-ci.org/sindresorhus/pify.svg?branch=master)](https://travis-ci.org/sindresorhus/pify)
+
+> Promisify a callback-style function
+
+
+## Install
+
+```
+$ npm install --save pify
+```
+
+
+## Usage
+
+```js
+const fs = require('fs');
+const pify = require('pify');
+
+// promisify a single function
+
+pify(fs.readFile)('package.json', 'utf8').then(data => {
+	console.log(JSON.parse(data).name);
+	//=> 'pify'
+});
+
+// or promisify all methods in a module
+
+pify(fs).readFile('package.json', 'utf8').then(data => {
+	console.log(JSON.parse(data).name);
+	//=> 'pify'
+});
+```
+
+
+## API
+
+### pify(input, [promiseModule], [options])
+
+Returns a promise wrapped version of the supplied function or module.
+
+#### input
+
+Type: `function`, `object`
+
+Callback-style function or module whose methods you want to promisify.
+
+#### promiseModule
+
+Type: `function`
+
+Custom promise module to use instead of the native one.
+
+Check out [`pinkie-promise`](https://github.com/floatdrop/pinkie-promise) if you need a tiny promise polyfill.
+
+#### options
+
+##### multiArgs
+
+Type: `boolean`  
+Default: `false`
+
+By default, the promisified function will only return the second argument from the callback, which works fine for most APIs. This option can be useful for modules like `request` that return multiple arguments. Turning this on will make it return an array of all arguments from the callback, excluding the error argument, instead of just the second argument.
+
+```js
+const request = require('request');
+const pify = require('pify');
+
+pify(request, {multiArgs: true})('https://sindresorhus.com').then(result => {
+	const [httpResponse, body] = result;
+});
+```
+
+##### include
+
+Type: `array` of (`string`|`regex`)
+
+Methods in a module to promisify. Remaining methods will be left untouched.
+
+##### exclude
+
+Type: `array` of (`string`|`regex`)  
+Default: `[/.+Sync$/]`
+
+Methods in a module **not** to promisify. Methods with names ending with `'Sync'` are excluded by default.
+
+##### excludeMain
+
+Type: `boolean`  
+Default: `false`
+
+By default, if given module is a function itself, this function will be promisified. Turn this option on if you want to promisify only methods of the module.
+
+```js
+const pify = require('pify');
+
+function fn() {
+	return true;
+}
+
+fn.method = (data, callback) => {
+	setImmediate(() => {
+		callback(data, null);
+	});
+};
+
+// promisify methods but not fn()
+const promiseFn = pify(fn, {excludeMain: true});
+
+if (promiseFn()) {
+	promiseFn.method('hi').then(data => {
+		console.log(data);
+	});
+}
+```

+> Itty bitty little widdle twinkie pinkie [ES2015 Promise](https://people.mozilla.org/~jorendorff/es6-draft.html#sec-promise-objects) implementation
+
+[![Build Status](https://travis-ci.org/floatdrop/pinkie.svg?branch=master)](https://travis-ci.org/floatdrop/pinkie)  [![Coverage Status](https://coveralls.io/repos/floatdrop/pinkie/badge.svg?branch=master&service=github)](https://coveralls.io/github/floatdrop/pinkie?branch=master)
+
+There are [tons of Promise implementations](https://github.com/promises-aplus/promises-spec/blob/master/implementations.md#standalone) out there, but all of them focus on browser compatibility and are often bloated with functionality.
+
+This module is an exact Promise specification polyfill (like [native-promise-only](https://github.com/getify/native-promise-only)), but in Node.js land (it should be browserify-able though).
+
+
+## Install
+
+```
+$ npm install --save pinkie
+```
+
+
+## Usage
+
+```js
+var fs = require('fs');
+var Promise = require('pinkie');
+
+new Promise(function (resolve, reject) {
+	fs.readFile('foo.json', 'utf8', function (err, data) {
+		if (err) {
+			reject(err);
+			return;
+		}
+
+		resolve(data);
+	});
+});
+//=> Promise
+```
+
+
+### API
+
+`pinkie` exports bare [ES2015 Promise](https://people.mozilla.org/~jorendorff/es6-draft.html#sec-promise-objects) implementation and polyfills [Node.js rejection events](https://nodejs.org/api/process.html#process_event_unhandledrejection). In case you forgot:
+
+#### new Promise(executor)
+
+Returns new instance of `Promise`.
+
+##### executor
+
+*Required*  
+Type: `function`
+
+Function with two arguments `resolve` and `reject`. The first argument fulfills the promise, the second argument rejects it.
+
+#### pinkie.all(promises)
+
+Returns a promise that resolves when all of the promises in the `promises` Array argument have resolved.
+
+#### pinkie.race(promises)
+
+Returns a promise that resolves or rejects as soon as one of the promises in the `promises` Array resolves or rejects, with the value or reason from that promise.
+
+#### pinkie.reject(reason)
+
+Returns a Promise object that is rejected with the given `reason`.
+
+#### pinkie.resolve(value)
+
+Returns a Promise object that is resolved with the given `value`. If the `value` is a thenable (i.e. has a then method), the returned promise will "follow" that thenable, adopting its eventual state; otherwise the returned promise will be fulfilled with the `value`.

+
+> Pluralize and singularize any word.
+
+## Installation
+
+```
+npm install pluralize --save
+yarn add pluralize
+bower install pluralize --save
+```
+
+### Node
+
+```javascript
+var pluralize = require('pluralize')
+```
+
+### AMD
+
+```javascript
+define(function (require, exports, module) {
+  var pluralize = require('pluralize')
+})
+```
+
+### `<script>` tag
+
+```html
+<script src="pluralize.js"></script>
+```
+
+## Why?
+
+This module uses a pre-defined list of rules, applied in order, to singularize or pluralize a given word. There are many cases where this is useful, such as any automation based on user input. For applications where the word(s) are known ahead of time, you can use a simple ternary (or function) which would be a much lighter alternative.
+
+## Usage
+
+```javascript
+pluralize('test') //=> "tests"
+pluralize('test', 1) //=> "test"
+pluralize('test', 5) //=> "tests"
+pluralize('test', 1, true) //=> "1 test"
+pluralize('test', 5, true) //=> "5 tests"
+pluralize('蘋果', 2, true) //=> "2 蘋果"
+
+pluralize.plural('regex') //=> "regexes"
+pluralize.addPluralRule(/gex$/i, 'gexii')
+pluralize.plural('regex') //=> "regexii"
+
+pluralize.singular('singles') //=> "single"
+pluralize.addSingularRule(/singles$/i, 'singular')
+pluralize.singular('singles') //=> "singular"
+
+pluralize.plural('irregular') //=> "irregulars"
+pluralize.addIrregularRule('irregular', 'regular')
+pluralize.plural('irregular') //=> "regular"
+
+pluralize.plural('paper') //=> "papers"
+pluralize.addUncountableRule('paper')
+pluralize.plural('paper') //=> "paper"
+
+pluralize.isPlural('test') //=> false
+pluralize.isSingular('test') //=> true
+```

+# prelude.ls [![Build Status](https://travis-ci.org/gkz/prelude-ls.png?branch=master)](https://travis-ci.org/gkz/prelude-ls)
+
+is a functionally oriented utility library. It is powerful and flexible. Almost all of its functions are curried. It is written in, and is the recommended base library for, <a href="http://livescript.net">LiveScript</a>.
+
+See **[the prelude.ls site](http://preludels.com)** for examples, a reference, and more.
+
+You can install via npm `npm install prelude-ls`
+
+### Development
+
+`make test` to test
+
+`make build` to build `lib` from `src`
+
+`make build-browser` to build browser versions

+Flexible ascii progress bar.
+
+## Installation
+
+```bash
+$ npm install progress
+```
+
+## Usage
+
+First we create a `ProgressBar`, giving it a format string
+as well as the `total`, telling the progress bar when it will
+be considered complete. After that all we need to do is `tick()` appropriately.
+
+```javascript
+var ProgressBar = require('progress');
+
+var bar = new ProgressBar(':bar', { total: 10 });
+var timer = setInterval(function () {
+  bar.tick();
+  if (bar.complete) {
+    console.log('\ncomplete\n');
+    clearInterval(timer);
+  }
+}, 100);
+```
+
+### Options
+
+These are keys in the options object you can pass to the progress bar along with
+`total` as seen in the example above.
+
+- `curr` current completed index
+- `total` total number of ticks to complete
+- `width` the displayed width of the progress bar defaulting to total
+- `stream` the output stream defaulting to stderr
+- `head` head character defaulting to complete character
+- `complete` completion character defaulting to "="
+- `incomplete` incomplete character defaulting to "-"
+- `renderThrottle` minimum time between updates in milliseconds defaulting to 16
+- `clear` option to clear the bar on completion defaulting to false
+- `callback` optional function to call when the progress bar completes
+
+### Tokens
+
+These are tokens you can use in the format of your progress bar.
+
+- `:bar` the progress bar itself
+- `:current` current tick number
+- `:total` total ticks
+- `:elapsed` time elapsed in seconds
+- `:percent` completion percentage
+- `:eta` estimated completion time in seconds
+- `:rate` rate of ticks per second
+
+### Custom Tokens
+
+You can define custom tokens by adding a `{'name': value}` object parameter to your method (`tick()`, `update()`, etc.) calls.
+
+```javascript
+var bar = new ProgressBar(':current: :token1 :token2', { total: 3 })
+bar.tick({
+  'token1': "Hello",
+  'token2': "World!\n"
+})
+bar.tick(2, {
+  'token1': "Goodbye",
+  'token2': "World!"
+})
+```
+The above example would result in the output below.
+
+```
+1: Hello World!
+3: Goodbye World!
+```
+
+## Examples
+
+### Download
+
+In our download example each tick has a variable influence, so we pass the chunk
+length which adjusts the progress bar appropriately relative to the total
+length.
+
+```javascript
+var ProgressBar = require('progress');
+var https = require('https');
+
+var req = https.request({
+  host: 'download.github.com',
+  port: 443,
+  path: '/visionmedia-node-jscoverage-0d4608a.zip'
+});
+
+req.on('response', function(res){
+  var len = parseInt(res.headers['content-length'], 10);
+
+  console.log();
+  var bar = new ProgressBar('  downloading [:bar] :rate/bps :percent :etas', {
+    complete: '=',
+    incomplete: ' ',
+    width: 20,
+    total: len
+  });
+
+  res.on('data', function (chunk) {
+    bar.tick(chunk.length);
+  });
+
+  res.on('end', function () {
+    console.log('\n');
+  });
+});
+
+req.end();
+```
+
+The above example result in a progress bar like the one below.
+
+```
+downloading [=====             ] 39/bps 29% 3.7s
+```
+
+### Interrupt
+
+To display a message during progress bar execution, use `interrupt()`
+```javascript
+var ProgressBar = require('progress');
+
+var bar = new ProgressBar(':bar :current/:total', { total: 10 });
+var timer = setInterval(function () {
+  bar.tick();
+  if (bar.complete) {
+    clearInterval(timer);
+  } else if (bar.curr === 5) {
+      bar.interrupt('this message appears above the progress bar\ncurrent progress is ' + bar.curr + '/' + bar.total);
+  }
+}, 1000);
+```
+
+You can see more examples in the `examples` folder.

+# pseudomap
+
+A thing that is a lot like ES6 `Map`, but without iterators, for use
+in environments where `for..of` syntax and `Map` are not available.
+
+If you need iterators, or just in general a more faithful polyfill to
+ES6 Maps, check out [es6-map](http://npm.im/es6-map).
+
+If you are in an environment where `Map` is supported, then that will
+be returned instead, unless `process.env.TEST_PSEUDOMAP` is set.
+
+You can use any value as keys, and any value as data.  Setting again
+with the identical key will overwrite the previous value.
+
+Internally, data is stored on an `Object.create(null)` style object.
+The key is coerced to a string to generate the key on the internal
+data-bag object.  The original key used is stored along with the data.
+
+In the event of a stringified-key collision, a new key is generated by
+appending an increasing number to the stringified-key until finding
+either the intended key or an empty spot.
+
+Note that because object traversal order of plain objects is not
+guaranteed to be identical to insertion order, the insertion order
+guarantee of `Map.prototype.forEach` is not guaranteed in this
+implementation.  However, in all versions of Node.js and V8 where this
+module works, `forEach` does traverse data in insertion order.
+
+## API
+
+Most of the [Map
+API](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map),
+with the following exceptions:
+
+1. A `Map` object is not an iterator.
+2. `values`, `keys`, and `entries` methods are not implemented,
+   because they return iterators.
+3. The argument to the constructor can be an Array of `[key, value]`
+   pairs, or a `Map` or `PseudoMap` object.  But, since iterators
+   aren't used, passing any plain-old iterator won't initialize the
+   map properly.
+
+## USAGE
+
+Use just like a regular ES6 Map.
+
+```javascript
+var PseudoMap = require('pseudomap')
+
+// optionally provide a pseudomap, or an array of [key,value] pairs
+// as the argument to initialize the map with
+var myMap = new PseudoMap()
+
+myMap.set(1, 'number 1')
+myMap.set('1', 'string 1')
+var akey = {}
+var bkey = {}
+myMap.set(akey, { some: 'data' })
+myMap.set(bkey, { some: 'other data' })
+```

+### Streams Working Group
+
+The Node.js Streams is jointly governed by a Working Group
+(WG)
+that is responsible for high-level guidance of the project.
+
+The WG has final authority over this project including:
+
+* Technical direction
+* Project governance and process (including this policy)
+* Contribution policy
+* GitHub repository hosting
+* Conduct guidelines
+* Maintaining the list of additional Collaborators
+
+For the current list of WG members, see the project
+[README.md](./README.md#current-project-team-members).
+
+### Collaborators
+
+The readable-stream GitHub repository is
+maintained by the WG and additional Collaborators who are added by the
+WG on an ongoing basis.
+
+Individuals making significant and valuable contributions are made
+Collaborators and given commit-access to the project. These
+individuals are identified by the WG and their addition as
+Collaborators is discussed during the WG meeting.
+
+_Note:_ If you make a significant contribution and are not considered
+for commit-access log an issue or contact a WG member directly and it
+will be brought up in the next WG meeting.
+
+Modifications of the contents of the readable-stream repository are
+made on
+a collaborative basis. Anybody with a GitHub account may propose a
+modification via pull request and it will be considered by the project
+Collaborators. All pull requests must be reviewed and accepted by a
+Collaborator with sufficient expertise who is able to take full
+responsibility for the change. In the case of pull requests proposed
+by an existing Collaborator, an additional Collaborator is required
+for sign-off. Consensus should be sought if additional Collaborators
+participate and there is disagreement around a particular
+modification. See _Consensus Seeking Process_ below for further detail
+on the consensus model used for governance.
+
+Collaborators may opt to elevate significant or controversial
+modifications, or modifications that have not found consensus to the
+WG for discussion by assigning the ***WG-agenda*** tag to a pull
+request or issue. The WG should serve as the final arbiter where
+required.
+
+For the current list of Collaborators, see the project
+[README.md](./README.md#members).
+
+### WG Membership
+
+WG seats are not time-limited.  There is no fixed size of the WG.
+However, the expected target is between 6 and 12, to ensure adequate
+coverage of important areas of expertise, balanced with the ability to
+make decisions efficiently.
+
+There is no specific set of requirements or qualifications for WG
+membership beyond these rules.
+
+The WG may add additional members to the WG by unanimous consensus.
+
+A WG member may be removed from the WG by voluntary resignation, or by
+unanimous consensus of all other WG members.
+
+Changes to WG membership should be posted in the agenda, and may be
+suggested as any other agenda item (see "WG Meetings" below).
+
+If an addition or removal is proposed during a meeting, and the full
+WG is not in attendance to participate, then the addition or removal
+is added to the agenda for the subsequent meeting.  This is to ensure
+that all members are given the opportunity to participate in all
+membership decisions.  If a WG member is unable to attend a meeting
+where a planned membership decision is being made, then their consent
+is assumed.
+
+No more than 1/3 of the WG members may be affiliated with the same
+employer.  If removal or resignation of a WG member, or a change of
+employment by a WG member, creates a situation where more than 1/3 of
+the WG membership shares an employer, then the situation must be
+immediately remedied by the resignation or removal of one or more WG
+members affiliated with the over-represented employer(s).
+
+### WG Meetings
+
+The WG meets occasionally on a Google Hangout On Air. A designated moderator
+approved by the WG runs the meeting. Each meeting should be
+published to YouTube.
+
+Items are added to the WG agenda that are considered contentious or
+are modifications of governance, contribution policy, WG membership,
+or release process.
+
+The intention of the agenda is not to approve or review all patches;
+that should happen continuously on GitHub and be handled by the larger
+group of Collaborators.
+
+Any community member or contributor can ask that something be added to
+the next meeting's agenda by logging a GitHub Issue. Any Collaborator,
+WG member or the moderator can add the item to the agenda by adding
+the ***WG-agenda*** tag to the issue.
+
+Prior to each WG meeting the moderator will share the Agenda with
+members of the WG. WG members can add any items they like to the
+agenda at the beginning of each meeting. The moderator and the WG
+cannot veto or remove items.
+
+The WG may invite persons or representatives from certain projects to
+participate in a non-voting capacity.
+
+The moderator is responsible for summarizing the discussion of each
+agenda item and sends it as a pull request after the meeting.
+
+### Consensus Seeking Process
+
+The WG follows a
+[Consensus
+Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making)
+decision-making model.
+
+When an agenda item has appeared to reach a consensus the moderator
+will ask "Does anyone object?" as a final call for dissent from the
+consensus.
+
+If an agenda item cannot reach a consensus a WG member can call for
+either a closing vote or a vote to table the issue to the next
+meeting. The call for a vote must be seconded by a majority of the WG
+or else the discussion will continue. Simple majority wins.
+
+Note that changes to WG membership require a majority consensus.  See
+"WG Membership" above.

+
+***Node-core streams for userland***
+
+This package is a mirror of the Streams2 and Streams3 implementations in
+Node-core.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.1.3/docs/api/stream.html).
+
+If you want to guarantee a stable streams base, regardless of what version of
+Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).
+
+As of version 2.0.0 **readable-stream** uses semantic versioning.
+
+# Streams Working Group
+
+`readable-stream` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+  project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+  notice of changes.

+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

+## API
+
+### `processor.use(parse)`
+
+Configure the `processor` to read markdown as input and process an
+[**MDAST**][mdast] syntax tree.
+
+#### `options`
+
+Options are passed later through [`processor.parse()`][parse],
+[`processor.process()`][process], or [`processor.pipe()`][pipe].
+The following settings are supported:
+
+*   [`gfm`][options-gfm] (`boolean`, default: `true`)
+*   [`yaml`][options-yaml] (`boolean`, default: `true`)
+*   [`commonmark`][options-commonmark] (`boolean`, default: `false`)
+*   [`footnotes`][options-footnotes] (`boolean`, default: `false`)
+*   [`pedantic`][options-pedantic] (`boolean`, default: `false`)
+*   [`breaks`][options-breaks] (`boolean`, default: `false`)
+*   [`blocks`][options-blocks] (`Array.<string>`, default: list of block HTML
+    elements)
+
+##### `options.gfm`
+
+```md
+hello ~~hi~~ world
+```
+
+GFM mode (default: `true`) turns on:
+
+*   [Fenced code blocks](https://help.github.com/articles/github-flavored-markdown/#fenced-code-blocks)
+*   [Autolinking of URLs](https://help.github.com/articles/github-flavored-markdown/#url-autolinking)
+*   [Deletions (strikethrough)](https://help.github.com/articles/github-flavored-markdown/#strikethrough)
+*   [Task lists](https://help.github.com/articles/writing-on-github/#task-lists)
+*   [Tables](https://help.github.com/articles/github-flavored-markdown/#tables)
+
+##### `options.yaml`
+
+```md
+---
+title: YAML is Cool
+---
+
+# YAML is Cool
+```
+
+YAML mode (default: `true`) enables raw YAML front matter to be detected
+at the top.
+
+##### `options.commonmark`
+
+```md
+This is a paragraph
+    and this is also part of the preceding paragraph.
+```
+
+CommonMark mode (default: `false`) allows:
+
+*   Empty lines to split blockquotes
+*   Parentheses (`(` and `)`) around for link and image titles
+*   Any escaped [ASCII-punctuation][escapes] character
+*   Closing parenthesis (`)`) as an ordered list marker
+*   URL definitions (and footnotes, when enabled) in blockquotes
+
+CommonMark mode disallows:
+
+*   Code directly following a paragraph
+*   ATX-headings (`# Hash headings`) without spacing after opening hashes
+    or and before closing hashes
+*   Setext headings (`Underline headings\n---`) when following a paragraph
+*   Newlines in link and image titles
+*   White space in link and image URLs in auto-links (links in brackets,
+    `<` and `>`)
+*   Lazy blockquote continuation, lines not preceded by a closing angle
+    bracket (`>`), for lists, code, and thematicBreak
+
+##### `options.footnotes`
+
+```md
+Something something[^or something?].
+
+And something else[^1].
+
+[^1]: This reference footnote contains a paragraph...
+
+    * ...and a list
+```
+
+Footnotes mode (default: `false`) enables reference footnotes and inline
+footnotes.  Both are wrapped in square brackets and preceded by a caret
+(`^`), and can be referenced from inside other footnotes.
+
+##### `options.breaks`
+
+```md
+This is a
+paragraph.
+```
+
+Breaks mode (default: `false`) exposes newline characters inside
+paragraphs as breaks.
+
+##### `options.blocks`
+
+```md
+<block>foo
+</block>
+```
+
+Blocks (default: a list of HTML block elements) exposes
+let’s users define block-level HTML elements.
+
+##### `options.pedantic`
+
+```md
+Check out some_file_name.txt
+```
+
+Pedantic mode (default: `false`) turns on:
+
+*   Emphasis (`_alpha_`) and importance (`__bravo__`) with underscores
+    in words
+*   Unordered lists with different markers (`*`, `-`, `+`)
+*   If `commonmark` is also turned on, ordered lists with different
+    markers (`.`, `)`)
+*   And pedantic mode removes less spaces in list-items (at most four,
+    instead of the whole indent)
+
+### `parse.Parser`
+
+Access to the [parser][], if you need it.
+
+## Extending the Parser
+
+Most often, using transformers to manipulate a syntax tree produces
+the desired output.  Sometimes, mainly when introducing new syntactic
+entities with a certain level of precedence, interfacing with the parser
+is necessary.
+
+If this plug-in is used, it adds a [`Parser`][parser] constructor to
+the `processor`.  Other plug-ins can add tokenizers to the parser’s
+prototype to change how markdown is parsed.
+
+The below plug-in adds a [tokenizer][] for at-mentions.
+
+```js
+module.exports = mentions;
+
+function mentions() {
+  var Parser = this.Parser;
+  var tokenizers = Parser.prototype.inlineTokenizers;
+  var methods = Parser.prototype.inlineMethods;
+
+  /* Add an inline tokenizer (defined in the following example). */
+  tokenizers.mention = tokenizeMention;
+
+  /* Run it just before `text`. */
+  methods.splice(methods.indexOf('text'), 0, 'mention');
+}
+```
+
+### `Parser#blockTokenizers`
+
+An object mapping tokenizer names to [tokenizer][]s.  These
+tokenizers (for example: `fencedCode`, `table`, and `paragraph`) eat
+from the start of a value to a line ending.
+
+### `Parser#blockMethods`
+
+Array of `blockTokenizers` names (`string`) specifying the order in
+which they run.
+
+### `Parser#inlineTokenizers`
+
+An object mapping tokenizer names to [tokenizer][]s.  These tokenizers
+(for example: `url`, `reference`, and `emphasis`) eat from the start
+of a value.  To increase performance, they depend on [locator][]s.
+
+### `Parser#inlineMethods`
+
+Array of `inlineTokenizers` names (`string`) specifying the order in
+which they run.
+
+### `function tokenizer(eat, value, silent)`
+
+```js
+tokenizeMention.notInLink = true;
+tokenizeMention.locator = locateMention;
+
+function tokenizeMention(eat, value, silent) {
+  var match = /^@(\w+)/.exec(value);
+
+  if (match) {
+    if (silent) {
+      return true;
+    }
+
+    return eat(match[0])({
+      type: 'link',
+      url: 'https://social-network/' + match[1],
+      children: [{type: 'text', value: match[0]}]
+    });
+  }
+}
+```
+
+The parser knows two types of tokenizers: block level and inline level.
+Block level tokenizers are the same as inline level tokenizers, with
+the exception that the latter must have a [locator][].
+
+Tokenizers _test_ whether a document starts with a certain syntactic
+entity.  In _silent_ mode, they return whether that test passes.
+In _normal_ mode, they consume that token, a process which is called
+“eating”.  Locators enable tokenizers to function faster by providing
+information on where the next entity may occur.
+
+###### Signatures
+
+*   `Node? = tokenizer(eat, value)`
+*   `boolean? = tokenizer(eat, value, silent)`
+
+###### Parameters
+
+*   `eat` ([`Function`][eat]) — Eat, when applicable, an entity
+*   `value` (`string`) — Value which may start an entity
+*   `silent` (`boolean`, optional) — Whether to detect or consume
+
+###### Properties
+
+*   `locator` ([`Function`][locator])
+    — Required for inline tokenizers
+*   `onlyAtStart` (`boolean`)
+    — Whether nodes can only be found at the beginning of the document
+*   `notInBlock` (`boolean`)
+    — Whether nodes cannot be in blockquotes, lists, or footnote
+    definitions
+*   `notInList` (`boolean`)
+    — Whether nodes cannot be in lists
+*   `notInLink` (`boolean`)
+    — Whether nodes cannot be in links
+
+###### Returns
+
+*   In _silent_ mode, whether a node can be found at the start of `value`
+*   In _normal_ mode, a node if it can be found at the start of `value`
+
+### `tokenizer.locator(value, fromIndex)`
+
+```js
+function locateMention(value, fromIndex) {
+  return value.indexOf('@', fromIndex);
+}
+```
+
+Locators are required for inline tokenization to keep the process
+performant.  Locators enable inline tokenizers to function faster by
+providing information on the where the next entity occurs.  Locators
+may be wrong, it’s OK if there actually isn’t a node to be found at
+the index they return, but they must skip any nodes.
+
+###### Parameters
+
+*   `value` (`string`) — Value which may contain an entity
+*   `fromIndex` (`number`) — Position to start searching at
+
+###### Returns
+
+Index at which an entity may start, and `-1` otherwise.
+
+### `eat(subvalue)`
+
+```js
+var add = eat('foo');
+```
+
+Eat `subvalue`, which is a string at the start of the
+[tokenize][tokenizer]d `value` (it’s tracked to ensure the correct
+value is eaten).
+
+###### Parameters
+
+*   `subvalue` (`string`) - Value to eat.
+
+###### Returns
+
+[`add`][add].
+
+### `add(node[, parent])`
+
+```js
+var add = eat('foo');
+add({type: 'text', value: 'foo'});
+```
+
+Add [positional information][location] to `node` and add it to `parent`.
+
+###### Parameters
+
+*   `node` ([`Node`][node]) - Node to patch position on and insert
+*   `parent` ([`Node`][node], optional) - Place to add `node` to in
+    the syntax tree.  Defaults to the currently processed node
+
+###### Returns
+
+The given `node`.
+
+### `add.test()`
+
+Get the [positional information][location] which would be patched on
+`node` by `add`.
+
+###### Returns
+
+[`Location`][location].
+
+### `add.reset(node[, parent])`
+
+`add`, but resets the internal location.  Useful for example in
+lists, where the same content is first eaten for a list, and later
+for list items
+
+###### Parameters
+
+*   `node` ([`Node`][node]) - Node to patch position on and insert
+*   `parent` ([`Node`][node], optional) - Place to add `node` to in
+    the syntax tree.  Defaults to the currently processed node
+
+###### Returns
+
+The given `node`.

+
+> Repeat the given string n times. Fastest implementation for repeating a string.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save repeat-string
+```
+
+## Usage
+
+### [repeat](index.js#L41)
+
+Repeat the given `string` the specified `number` of times.
+
+**Example:**
+
+**Example**
+
+```js
+var repeat = require('repeat-string');
+repeat('A', 5);
+//=> AAAAA
+```
+
+**Params**
+
+* `string` **{String}**: The string to repeat
+* `number` **{Number}**: The number of times to repeat the string
+* `returns` **{String}**: Repeated string
+
+## Benchmarks
+
+Repeat string is significantly faster than the native method (which is itself faster than [repeating](https://github.com/sindresorhus/repeating)):
+
+```sh

+
+> Resolve the path of a module like [`require.resolve()`](http://nodejs.org/api/globals.html#globals_require_resolve) but from a given path
+
+
+## Install
+
+```
+$ npm install --save resolve-from
+```
+
+
+## Usage
+
+```js
+const resolveFrom = require('resolve-from');
+
+// there's a file at `./foo/bar.js`
+
+resolveFrom('foo', './bar');
+//=> '/Users/sindresorhus/dev/test/foo/bar.js'
+```
+
+
+## API
+
+### resolveFrom(fromDir, moduleId)
+
+#### fromDir
+
+Type: `string`
+
+The directory to resolve from.
+
+#### moduleId
+
+Type: `string`
+
+What you would use in `require()`.
+
+
+## Tip
+
+Create a partial using a bound function if you want to require from the same `fromDir` multiple times:
+
+```js
+const resolveFromFoo = resolveFrom.bind(null, 'foo');
+
+resolveFromFoo('./bar');
+resolveFromFoo('./baz');
+```

+
+The [UNIX command](http://en.wikipedia.org/wiki/Rm_(Unix)) `rm -rf` for node.
+
+Install with `npm install rimraf`, or just drop rimraf.js somewhere.
+
+## API
+
+`rimraf(f, [opts], callback)`
+
+The first parameter will be interpreted as a globbing pattern for files. If you
+want to disable globbing you can do so with `opts.disableGlob` (defaults to
+`false`). This might be handy, for instance, if you have filenames that contain
+globbing wildcard characters.
+
+The callback will be called with an error if there is one.  Certain
+errors are handled for you:
+
+* Windows: `EBUSY` and `ENOTEMPTY` - rimraf will back off a maximum of
+  `opts.maxBusyTries` times before giving up, adding 100ms of wait
+  between each attempt.  The default `maxBusyTries` is 3.
+* `ENOENT` - If the file doesn't exist, rimraf will return
+  successfully, since your desired outcome is already the case.
+* `EMFILE` - Since `readdir` requires opening a file descriptor, it's
+  possible to hit `EMFILE` if too many file descriptors are in use.
+  In the sync case, there's nothing to be done for this.  But in the
+  async case, rimraf will gradually back off with timeouts up to
+  `opts.emfileWait` ms, which defaults to 1000.
+
+## options
+
+* unlink, chmod, stat, lstat, rmdir, readdir,
+  unlinkSync, chmodSync, statSync, lstatSync, rmdirSync, readdirSync
+
+    In order to use a custom file system library, you can override
+    specific fs functions on the options object.
+
+    If any of these functions are present on the options object, then
+    the supplied function will be used instead of the default fs
+    method.
+
+    Sync methods are only relevant for `rimraf.sync()`, of course.
+
+    For example:
+
+    ```javascript
+    var myCustomFS = require('some-custom-fs')
+
+    rimraf('some-thing', myCustomFS, callback)
+    ```
+
+* maxBusyTries
+
+    If an `EBUSY`, `ENOTEMPTY`, or `EPERM` error code is encountered
+    on Windows systems, then rimraf will retry with a linear backoff
+    wait of 100ms longer on each try.  The default maxBusyTries is 3.
+
+    Only relevant for async usage.
+
+* emfileWait
+
+    If an `EMFILE` error is encountered, then rimraf will retry
+    repeatedly with a linear backoff of 1ms longer on each try, until
+    the timeout counter hits this max.  The default limit is 1000.
+
+    If you repeatedly encounter `EMFILE` errors, then consider using
+    [graceful-fs](http://npm.im/graceful-fs) in your program.
+
+    Only relevant for async usage.
+
+* glob
+
+    Set to `false` to disable [glob](http://npm.im/glob) pattern
+    matching.
+
+    Set to an object to pass options to the glob module.  The default
+    glob options are `{ nosort: true, silent: true }`.
+
+    Glob version 6 is used in this module.
+
+    Relevant for both sync and async usage.
+
+* disableGlob
+
+    Set to any non-falsey value to disable globbing entirely.
+    (Equivalent to setting `glob: false`.)
+
+## rimraf.sync
+
+It can remove stuff synchronously, too.  But that's not so good.  Use
+the async API.  It's better.
+
+## CLI
+
+If installed with `npm install rimraf -g` it can be used as a global
+command `rimraf <path> [<path> ...]` which is useful for cross platform support.
+
+## mkdirp
+
+If you need to create a directory recursively, check out
+[mkdirp](https://github.com/substack/node-mkdirp).

+Run Async
+=========
+
+[![npm](https://badge.fury.io/js/run-async.svg)](http://badge.fury.io/js/run-async) [![tests](https://travis-ci.org/SBoudrias/run-async.svg?branch=master)](http://travis-ci.org/SBoudrias/run-async) [![dependencies](https://david-dm.org/SBoudrias/run-async.svg?theme=shields.io)](https://david-dm.org/SBoudrias/run-async)
+
+Utility method to run a function either synchronously or asynchronously using a series of common patterns. This is useful for library author accepting sync or async functions as parameter. `runAsync` will always run them as an async method, and normalize the multiple signature.
+
+Installation
+=========
+
+```bash
+npm install --save run-async
+```
+
+Usage
+=========
+
+Here's a simple example print the function results and three options a user can provide a function.
+
+```js
+var runAsync = require('run-async');
+
+var printAfter = function (func) {
+  var cb = function (err, returnValue) {
+    console.log(returnValue);
+  };
+  runAsync(func, cb)(/* arguments for func */);
+};
+```
+
+#### Using `this.async`
+```js
+printAfter(function () {
+  var done = this.async();
+
+  setTimeout(function () {
+    done(null, 'done running with callback');
+  }, 10);
+});
+```
+
+#### Returning a promise
+```js
+printAfter(function () {
+  return new Promise(function (resolve, reject) {
+    resolve('done running with promises');
+  });
+});
+```
+
+#### Synchronous function
+```js
+printAfter(function () {
+  return 'done running sync function';
+});
+```
+
+### runAsync.cb
+
+`runAsync.cb` supports all the function types that `runAsync` does and additionally a traditional **callback as the last argument** signature:
+
+```js
+var runAsync = require('run-async');
+
+// IMPORTANT: The wrapped function must have a fixed number of parameters.
+runAsync.cb(function(a, b, cb) {
+  cb(null, a + b);
+}, function(err, result) {
+  console.log(result)
+})(1, 2)
+```
+
+If your version of node support Promises natively (node >= 0.12), `runAsync` will return a promise. Example: `runAsync(func)(arg1, arg2).then(cb)`

+# RxJS Aggregates Module #
+
+The Reactive Extensions for JavaScript has a number of aggregation operators including those you might already know from the Array#extras and the upcoming ES6 standard such as `reduce`, `find` and `findIndex`.  This module is used exclusively for aggregation operations used on finite observable sequences.  In addition to the aforementioned operators, there are many useful operators such as `count`, `sum`, `average` and determining whether two sequences are equal via the `sequenceEqual` method.  This requires `rx.lite.js` from the [`rx-lite`](https://www.npmjs.com/package/rx-lite) NPM module.
+
+## Getting Started
+
+There are a number of ways to get started with RxJS.
+
+### Installing with [NPM](https://npmjs.org/)
+
+```bash`
+$ npm install rx-lite-aggregates
+$ npm install -g rx-lite-aggregates
+```
+
+### Using with Node.js and Ringo.js
+
+```js
+var Rx = require('rx-lite-aggregates');
+```
+
+### In a Browser:
+
+```html
+<!-- Just the core RxJS -->
+<script src="path/to/rx.lite.js"></script>
+<script src="path/to/rx.lite.aggregates.js"></script>
+```
+

+# RxJS Lite Module #
+
+The Reactive Extensions for JavaScript Lite version is a lightweight version of the Reactive Extensions for JavaScript which covers most of the day to day operators you might use all in a single library.  Functionality such as bridging to events, promises, callbacks, Node.js-style callbacks, time-based operations and more are built right in.  This comes with `rx.lite.js` which is for use in modern development environments such as > IE9 and server-side environments such as Node.js.
+
+## Getting Started
+
+There are a number of ways to get started with RxJS.
+
+### Installing with [NPM](https://npmjs.org/)
+
+```bash`
+$ npm install rx-lite
+$ npm install -g rx-lite
+```
+
+### Using with Node.js and Ringo.js
+
+```js
+var Rx = require('rx-lite');
+```
+
+### In a Browser:
+
+```html
+<!-- Just the core RxJS -->
+<script src="path/to/rx.lite.js"></script>
+```
+

+## Contributing ##
+
+There are lots of ways to contribute to the project, and we appreciate our [contributors](https://github.com/Reactive-Extensions/RxJS/wiki/Contributors).  If you wish to contribute, check out our [style guide]((https://github.com/Reactive-Extensions/RxJS/tree/master/doc/contributing)).
+
+You can contribute by reviewing and sending feedback on code checkins, suggesting and trying out new features as they are implemented, submit bugs and help us verify fixes as they are checked in, as well as submit code fixes or code contributions of your own. Note that all code submissions will be rigorously reviewed and tested by the Rx Team, and only those that meet an extremely high bar for both quality and design/roadmap appropriateness will be merged into the source.

+#### Safer Node.js Buffer API
+
+**Use the new Node.js Buffer APIs (`Buffer.from`, `Buffer.alloc`,
+`Buffer.allocUnsafe`, `Buffer.allocUnsafeSlow`) in all versions of Node.js.**
+
+**Uses the built-in implementation when available.**
+
+## install
+
+```
+npm install safe-buffer
+```
+
+## usage
+
+The goal of this package is to provide a safe replacement for the node.js `Buffer`.
+
+It's a drop-in replacement for `Buffer`. You can use it by adding one `require` line to
+the top of your node.js modules:
+
+```js
+var Buffer = require('safe-buffer').Buffer
+
+// Existing buffer code will continue to work without issues:
+
+new Buffer('hey', 'utf8')
+new Buffer([1, 2, 3], 'utf8')
+new Buffer(obj)
+new Buffer(16) // create an uninitialized buffer (potentially unsafe)
+
+// But you can use these new explicit APIs to make clear what you want:
+
+Buffer.from('hey', 'utf8') // convert from many types to a Buffer
+Buffer.alloc(16) // create a zero-filled buffer (safe)
+Buffer.allocUnsafe(16) // create an uninitialized buffer (potentially unsafe)
+```
+
+## api
+
+### Class Method: Buffer.from(array)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `array` {Array}
+
+Allocates a new `Buffer` using an `array` of octets.
+
+```js
+const buf = Buffer.from([0x62,0x75,0x66,0x66,0x65,0x72]);
+  // creates a new Buffer containing ASCII bytes
+  // ['b','u','f','f','e','r']
+```
+
+A `TypeError` will be thrown if `array` is not an `Array`.
+
+### Class Method: Buffer.from(arrayBuffer[, byteOffset[, length]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `arrayBuffer` {ArrayBuffer} The `.buffer` property of a `TypedArray` or
+  a `new ArrayBuffer()`
+* `byteOffset` {Number} Default: `0`
+* `length` {Number} Default: `arrayBuffer.length - byteOffset`
+
+When passed a reference to the `.buffer` property of a `TypedArray` instance,
+the newly created `Buffer` will share the same allocated memory as the
+TypedArray.
+
+```js
+const arr = new Uint16Array(2);
+arr[0] = 5000;
+arr[1] = 4000;
+
+const buf = Buffer.from(arr.buffer); // shares the memory with arr;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 a0 0f>
+
+// changing the TypedArray changes the Buffer also
+arr[1] = 6000;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 70 17>
+```
+
+The optional `byteOffset` and `length` arguments specify a memory range within
+the `arrayBuffer` that will be shared by the `Buffer`.
+
+```js
+const ab = new ArrayBuffer(10);
+const buf = Buffer.from(ab, 0, 2);
+console.log(buf.length);
+  // Prints: 2
+```
+
+A `TypeError` will be thrown if `arrayBuffer` is not an `ArrayBuffer`.
+
+### Class Method: Buffer.from(buffer)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `buffer` {Buffer}
+
+Copies the passed `buffer` data onto a new `Buffer` instance.
+
+```js
+const buf1 = Buffer.from('buffer');
+const buf2 = Buffer.from(buf1);
+
+buf1[0] = 0x61;
+console.log(buf1.toString());
+  // 'auffer'
+console.log(buf2.toString());
+  // 'buffer' (copy is not changed)
+```
+
+A `TypeError` will be thrown if `buffer` is not a `Buffer`.
+
+### Class Method: Buffer.from(str[, encoding])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `str` {String} String to encode.
+* `encoding` {String} Encoding to use, Default: `'utf8'`
+
+Creates a new `Buffer` containing the given JavaScript string `str`. If
+provided, the `encoding` parameter identifies the character encoding.
+If not provided, `encoding` defaults to `'utf8'`.
+
+```js
+const buf1 = Buffer.from('this is a tést');
+console.log(buf1.toString());
+  // prints: this is a tést
+console.log(buf1.toString('ascii'));
+  // prints: this is a tC)st
+
+const buf2 = Buffer.from('7468697320697320612074c3a97374', 'hex');
+console.log(buf2.toString());
+  // prints: this is a tést
+```
+
+A `TypeError` will be thrown if `str` is not a string.
+
+### Class Method: Buffer.alloc(size[, fill[, encoding]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+* `fill` {Value} Default: `undefined`
+* `encoding` {String} Default: `utf8`
+
+Allocates a new `Buffer` of `size` bytes. If `fill` is `undefined`, the
+`Buffer` will be *zero-filled*.
+
+```js
+const buf = Buffer.alloc(5);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+The `size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+If `fill` is specified, the allocated `Buffer` will be initialized by calling
+`buf.fill(fill)`. See [`buf.fill()`][] for more information.
+
+```js
+const buf = Buffer.alloc(5, 'a');
+console.log(buf);
+  // <Buffer 61 61 61 61 61>
+```
+
+If both `fill` and `encoding` are specified, the allocated `Buffer` will be
+initialized by calling `buf.fill(fill, encoding)`. For example:
+
+```js
+const buf = Buffer.alloc(11, 'aGVsbG8gd29ybGQ=', 'base64');
+console.log(buf);
+  // <Buffer 68 65 6c 6c 6f 20 77 6f 72 6c 64>
+```
+
+Calling `Buffer.alloc(size)` can be significantly slower than the alternative
+`Buffer.allocUnsafe(size)` but ensures that the newly created `Buffer` instance
+contents will *never contain sensitive data*.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### Class Method: Buffer.allocUnsafe(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* `Buffer` of `size` bytes.  The `size` must
+be less than or equal to the value of `require('buffer').kMaxLength` (on 64-bit
+architectures, `kMaxLength` is `(2^31)-1`). Otherwise, a [`RangeError`][] is
+thrown. A zero-length Buffer will be created if a `size` less than or equal to
+0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+```js
+const buf = Buffer.allocUnsafe(5);
+console.log(buf);
+  // <Buffer 78 e0 82 02 01>
+  // (octets will be different, every time)
+buf.fill(0);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+A `TypeError` will be thrown if `size` is not a number.
+
+Note that the `Buffer` module pre-allocates an internal `Buffer` instance of
+size `Buffer.poolSize` that is used as a pool for the fast allocation of new
+`Buffer` instances created using `Buffer.allocUnsafe(size)` (and the deprecated
+`new Buffer(size)` constructor) only when `size` is less than or equal to
+`Buffer.poolSize >> 1` (floor of `Buffer.poolSize` divided by two). The default
+value of `Buffer.poolSize` is `8192` but can be modified.
+
+Use of this pre-allocated internal memory pool is a key difference between
+calling `Buffer.alloc(size, fill)` vs. `Buffer.allocUnsafe(size).fill(fill)`.
+Specifically, `Buffer.alloc(size, fill)` will *never* use the internal Buffer
+pool, while `Buffer.allocUnsafe(size).fill(fill)` *will* use the internal
+Buffer pool if `size` is less than or equal to half `Buffer.poolSize`. The
+difference is subtle but can be important when an application requires the
+additional performance that `Buffer.allocUnsafe(size)` provides.
+
+### Class Method: Buffer.allocUnsafeSlow(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* and non-pooled `Buffer` of `size` bytes.  The
+`size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances,
+allocations under 4KB are, by default, sliced from a single pre-allocated
+`Buffer`. This allows applications to avoid the garbage collection overhead of
+creating many individually allocated Buffers. This approach improves both
+performance and memory usage by eliminating the need to track and cleanup as
+many `Persistent` objects.
+
+However, in the case where a developer may need to retain a small chunk of
+memory from a pool for an indeterminate amount of time, it may be appropriate
+to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then
+copy out the relevant bits.
+
+```js
+// need to keep around a few small chunks of memory
+const store = [];
+
+socket.on('readable', () => {
+  const data = socket.read();
+  // allocate for retained data
+  const sb = Buffer.allocUnsafeSlow(10);
+  // copy the data into the new allocation
+  data.copy(sb, 0, 0, 10);
+  store.push(sb);
+});
+```
+
+Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after*
+a developer has observed undue memory retention in their applications.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### All the Rest
+
+The rest of the `Buffer` API is exactly the same as in node.js.
+[See the docs](https://nodejs.org/api/buffer.html).
+
+
+## Related links
+
+- [Node.js issue: Buffer(number) is unsafe](https://github.com/nodejs/node/issues/4660)
+- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4)
+
+## Why is `Buffer` unsafe?
+
+Today, the node.js `Buffer` constructor is overloaded to handle many different argument
+types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.),
+`ArrayBuffer`, and also `Number`.
+
+The API is optimized for convenience: you can throw any type at it, and it will try to do
+what you want.
+
+Because the Buffer constructor is so powerful, you often see code like this:
+
+```js
+// Convert UTF-8 strings to hex
+function toHex (str) {
+  return new Buffer(str).toString('hex')
+}
+```
+
+***But what happens if `toHex` is called with a `Number` argument?***
+
+### Remote Memory Disclosure
+
+If an attacker can make your program call the `Buffer` constructor with a `Number`
+argument, then they can make it allocate uninitialized memory from the node.js process.
+This could potentially disclose TLS private keys, user data, or database passwords.
+
+When the `Buffer` constructor is passed a `Number` argument, it returns an
+**UNINITIALIZED** block of memory of the specified `size`. When you create a `Buffer` like
+this, you **MUST** overwrite the contents before returning it to the user.
+
+From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size):
+
+> `new Buffer(size)`
+>
+> - `size` Number
+>
+> The underlying memory for `Buffer` instances created in this way is not initialized.
+> **The contents of a newly created `Buffer` are unknown and could contain sensitive
+> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes.
+
+(Emphasis our own.)
+
+Whenever the programmer intended to create an uninitialized `Buffer` you often see code
+like this:
+
+```js
+var buf = new Buffer(16)
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### Would this ever be a problem in real code?
+
+Yes. It's surprisingly common to forget to check the type of your variables in a
+dynamically-typed language like JavaScript.
+
+Usually the consequences of assuming the wrong type is that your program crashes with an
+uncaught exception. But the failure mode for forgetting to check the type of arguments to
+the `Buffer` constructor is more catastrophic.
+
+Here's an example of a vulnerable service that takes a JSON payload and converts it to
+hex:
+
+```js
+// Take a JSON payload {str: "some string"} and convert it to hex
+var server = http.createServer(function (req, res) {
+  var data = ''
+  req.setEncoding('utf8')
+  req.on('data', function (chunk) {
+    data += chunk
+  })
+  req.on('end', function () {
+    var body = JSON.parse(data)
+    res.end(new Buffer(body.str).toString('hex'))
+  })
+})
+
+server.listen(8080)
+```
+
+In this example, an http client just has to send:
+
+```json
+{
+  "str": 1000
+}
+```
+
+and it will get back 1,000 bytes of uninitialized memory from the server.
+
+This is a very serious bug. It's similar in severity to the
+[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process
+memory by remote attackers.
+
+
+### Which real-world packages were vulnerable?
+
+#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht)
+
+[Mathias Buus](https://github.com/mafintosh) and I
+([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages,
+[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow
+anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get
+them to reveal 20 bytes at a time of uninitialized memory from the node.js process.
+
+Here's
+[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8)
+that fixed it. We released a new fixed version, created a
+[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all
+vulnerable versions on npm so users will get a warning to upgrade to a newer version.
+
+#### [`ws`](https://www.npmjs.com/package/ws)
+
+That got us wondering if there were other vulnerable packages. Sure enough, within a short
+period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the
+most popular WebSocket implementation in node.js.
+
+If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as
+expected, then uninitialized server memory would be disclosed to the remote peer.
+
+These were the vulnerable methods:
+
+```js
+socket.send(number)
+socket.ping(number)
+socket.pong(number)
+```
+
+Here's a vulnerable socket server with some echo functionality:
+
+```js
+server.on('connection', function (socket) {
+  socket.on('message', function (message) {
+    message = JSON.parse(message)
+    if (message.type === 'echo') {
+      socket.send(message.data) // send back the user's message
+    }
+  })
+})
+```
+
+`socket.send(number)` called on the server, will disclose server memory.
+
+Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue
+was fixed, with a more detailed explanation. Props to
+[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the
+[Node Security Project disclosure](https://nodesecurity.io/advisories/67).
+
+
+### What's the solution?
+
+It's important that node.js offers a fast way to get memory otherwise performance-critical
+applications would needlessly get a lot slower.
+
+But we need a better way to *signal our intent* as programmers. **When we want
+uninitialized memory, we should request it explicitly.**
+
+Sensitive functionality should not be packed into a developer-friendly API that loosely
+accepts many different types. This type of API encourages the lazy practice of passing
+variables in without checking the type very carefully.
+
+#### A new API: `Buffer.allocUnsafe(number)`
+
+The functionality of creating buffers with uninitialized memory should be part of another
+API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that
+frequently gets user input of all sorts of different types passed into it.
+
+```js
+var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory!
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### How do we fix node.js core?
+
+We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as
+`semver-major`) which defends against one case:
+
+```js
+var str = 16
+new Buffer(str, 'utf8')
+```
+
+In this situation, it's implied that the programmer intended the first argument to be a
+string, since they passed an encoding as a second argument. Today, node.js will allocate
+uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not
+what the programmer intended.
+
+But this is only a partial solution, since if the programmer does `new Buffer(variable)`
+(without an `encoding` parameter) there's no way to know what they intended. If `variable`
+is sometimes a number, then uninitialized memory will sometimes be returned.
+
+### What's the real long-term fix?
+
+We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when
+we need uninitialized memory. But that would break 1000s of packages.
+
+~~We believe the best solution is to:~~
+
+~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~
+
+~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~
+
+#### Update
+
+We now support adding three new APIs:
+
+- `Buffer.from(value)` - convert from any type to a buffer
+- `Buffer.alloc(size)` - create a zero-filled buffer
+- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size
+
+This solves the core problem that affected `ws` and `bittorrent-dht` which is
+`Buffer(variable)` getting tricked into taking a number argument.
+
+This way, existing code continues working and the impact on the npm ecosystem will be
+minimal. Over time, npm maintainers can migrate performance-critical code to use
+`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`.
+
+
+### Conclusion
+
+We think there's a serious design issue with the `Buffer` API as it exists today. It
+promotes insecure software by putting high-risk functionality into a convenient API
+with friendly "developer ergonomics".
+
+This wasn't merely a theoretical exercise because we found the issue in some of the
+most popular npm packages.
+
+Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of
+`buffer`.
+
+```js
+var Buffer = require('safe-buffer').Buffer
+```
+
+Eventually, we hope that node.js core can switch to this new, safer behavior. We believe
+the impact on the ecosystem would be minimal since it's not a breaking change.
+Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while
+older, insecure packages would magically become safe from this attack vector.

+semver(1) -- The semantic versioner for npm
+===========================================
+
+## Install
+
+```bash
+npm install --save semver
+````
+
+## Usage
+
+As a node module:
+
+```js
+const semver = require('semver')
+
+semver.valid('1.2.3') // '1.2.3'
+semver.valid('a.b.c') // null
+semver.clean('  =v1.2.3   ') // '1.2.3'
+semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
+semver.gt('1.2.3', '9.8.7') // false
+semver.lt('1.2.3', '9.8.7') // true
+```
+
+As a command-line utility:
+
+```
+$ semver -h
+
+SemVer 5.3.0
+
+A JavaScript implementation of the http://semver.org/ specification
+Copyright Isaac Z. Schlueter
+
+Usage: semver [options] <version> [<version> [...]]
+Prints valid versions sorted by SemVer precedence
+
+Options:
+-r --range <range>
+        Print versions that match the specified range.
+
+-i --increment [<level>]
+        Increment a version by the specified level.  Level can
+        be one of: major, minor, patch, premajor, preminor,
+        prepatch, or prerelease.  Default level is 'patch'.
+        Only one version may be specified.
+
+--preid <identifier>
+        Identifier to be used to prefix premajor, preminor,
+        prepatch or prerelease version increments.
+
+-l --loose
+        Interpret versions and ranges loosely
+
+Program exits successfully if any valid version satisfies
+all supplied ranges, and prints all satisfying versions.
+
+If no satisfying versions are found, then exits failure.
+
+Versions are printed in ascending order, so supplying
+multiple versions to the utility will just sort them.
+```
+
+## Versions
+
+A "version" is described by the `v2.0.0` specification found at
+<http://semver.org/>.
+
+A leading `"="` or `"v"` character is stripped off and ignored.
+
+## Ranges
+
+A `version range` is a set of `comparators` which specify versions
+that satisfy the range.
+
+A `comparator` is composed of an `operator` and a `version`.  The set
+of primitive `operators` is:
+
+* `<` Less than
+* `<=` Less than or equal to
+* `>` Greater than
+* `>=` Greater than or equal to
+* `=` Equal.  If no operator is specified, then equality is assumed,
+  so this operator is optional, but MAY be included.
+
+For example, the comparator `>=1.2.7` would match the versions
+`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
+or `1.1.0`.
+
+Comparators can be joined by whitespace to form a `comparator set`,
+which is satisfied by the **intersection** of all of the comparators
+it includes.
+
+A range is composed of one or more comparator sets, joined by `||`.  A
+version matches a range if and only if every comparator in at least
+one of the `||`-separated comparator sets is satisfied by the version.
+
+For example, the range `>=1.2.7 <1.3.0` would match the versions
+`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
+or `1.1.0`.
+
+The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
+`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
+
+### Prerelease Tags
+
+If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
+it will only be allowed to satisfy comparator sets if at least one
+comparator with the same `[major, minor, patch]` tuple also has a
+prerelease tag.
+
+For example, the range `>1.2.3-alpha.3` would be allowed to match the
+version `1.2.3-alpha.7`, but it would *not* be satisfied by
+`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
+than" `1.2.3-alpha.3` according to the SemVer sort rules.  The version
+range only accepts prerelease tags on the `1.2.3` version.  The
+version `3.4.5` *would* satisfy the range, because it does not have a
+prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
+
+The purpose for this behavior is twofold.  First, prerelease versions
+frequently are updated very quickly, and contain many breaking changes
+that are (by the author's design) not yet fit for public consumption.
+Therefore, by default, they are excluded from range matching
+semantics.
+
+Second, a user who has opted into using a prerelease version has
+clearly indicated the intent to use *that specific* set of
+alpha/beta/rc versions.  By including a prerelease tag in the range,
+the user is indicating that they are aware of the risk.  However, it
+is still not appropriate to assume that they have opted into taking a
+similar risk on the *next* set of prerelease versions.
+
+#### Prerelease Identifiers
+
+The method `.inc` takes an additional `identifier` string argument that
+will append the value of the string as a prerelease identifier:
+
+```javascript
+semver.inc('1.2.3', 'prerelease', 'beta')
+// '1.2.4-beta.0'
+```
+
+command-line example:
+
+```bash
+$ semver 1.2.3 -i prerelease --preid beta
+1.2.4-beta.0
+```
+
+Which then can be used to increment further:
+
+```bash
+$ semver 1.2.4-beta.0 -i prerelease
+1.2.4-beta.1
+```
+
+### Advanced Range Syntax
+
+Advanced range syntax desugars to primitive comparators in
+deterministic ways.
+
+Advanced ranges may be combined in the same way as primitive
+comparators using white space or `||`.
+
+#### Hyphen Ranges `X.Y.Z - A.B.C`
+
+Specifies an inclusive set.
+
+* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
+
+If a partial version is provided as the first version in the inclusive
+range, then the missing pieces are replaced with zeroes.
+
+* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
+
+If a partial version is provided as the second version in the
+inclusive range, then all versions that start with the supplied parts
+of the tuple are accepted, but nothing that would be greater than the
+provided tuple parts.
+
+* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0`
+* `1.2.3 - 2` := `>=1.2.3 <3.0.0`
+
+#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
+
+Any of `X`, `x`, or `*` may be used to "stand in" for one of the
+numeric values in the `[major, minor, patch]` tuple.
+
+* `*` := `>=0.0.0` (Any version satisfies)
+* `1.x` := `>=1.0.0 <2.0.0` (Matching major version)
+* `1.2.x` := `>=1.2.0 <1.3.0` (Matching major and minor versions)
+
+A partial version range is treated as an X-Range, so the special
+character is in fact optional.
+
+* `""` (empty string) := `*` := `>=0.0.0`
+* `1` := `1.x.x` := `>=1.0.0 <2.0.0`
+* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0`
+
+#### Tilde Ranges `~1.2.3` `~1.2` `~1`
+
+Allows patch-level changes if a minor version is specified on the
+comparator.  Allows minor-level changes if not.
+
+* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0`
+* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0` (Same as `1.2.x`)
+* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0` (Same as `1.x`)
+* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0`
+* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0` (Same as `0.2.x`)
+* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0` (Same as `0.x`)
+* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+
+#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
+
+Allows changes that do not modify the left-most non-zero digit in the
+`[major, minor, patch]` tuple.  In other words, this allows patch and
+minor updates for versions `1.0.0` and above, patch updates for
+versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
+
+Many authors treat a `0.x` version as if the `x` were the major
+"breaking-change" indicator.
+
+Caret ranges are ideal when an author may make breaking changes
+between `0.2.4` and `0.3.0` releases, which is a common practice.
+However, it presumes that there will *not* be breaking changes between
+`0.2.4` and `0.2.5`.  It allows for changes that are presumed to be
+additive (but non-breaking), according to commonly observed practices.
+
+* `^1.2.3` := `>=1.2.3 <2.0.0`
+* `^0.2.3` := `>=0.2.3 <0.3.0`
+* `^0.0.3` := `>=0.0.3 <0.0.4`
+* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4`  Note that prereleases in the
+  `0.0.3` version *only* will be allowed, if they are greater than or
+  equal to `beta`.  So, `0.0.3-pr.2` would be allowed.
+
+When parsing caret ranges, a missing `patch` value desugars to the
+number `0`, but will allow flexibility within that value, even if the
+major and minor versions are both `0`.
+
+* `^1.2.x` := `>=1.2.0 <2.0.0`
+* `^0.0.x` := `>=0.0.0 <0.1.0`
+* `^0.0` := `>=0.0.0 <0.1.0`
+
+A missing `minor` and `patch` values will desugar to zero, but also
+allow flexibility within those values, even if the major version is
+zero.
+
+* `^1.x` := `>=1.0.0 <2.0.0`
+* `^0.x` := `>=0.0.0 <1.0.0`
+
+### Range Grammar
+
+Putting all this together, here is a Backus-Naur grammar for ranges,
+for the benefit of parser authors:
+
+```bnf
+range-set  ::= range ( logical-or range ) *
+logical-or ::= ( ' ' ) * '||' ( ' ' ) *
+range      ::= hyphen | simple ( ' ' simple ) * | ''
+hyphen     ::= partial ' - ' partial
+simple     ::= primitive | partial | tilde | caret
+primitive  ::= ( '<' | '>' | '>=' | '<=' | '=' | ) partial
+partial    ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
+xr         ::= 'x' | 'X' | '*' | nr
+nr         ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
+tilde      ::= '~' partial
+caret      ::= '^' partial
+qualifier  ::= ( '-' pre )? ( '+' build )?
+pre        ::= parts
+build      ::= parts
+parts      ::= part ( '.' part ) *
+part       ::= nr | [-0-9A-Za-z]+
+```
+
+## Functions
+
+All methods and classes take a final `loose` boolean argument that, if
+true, will be more forgiving about not-quite-valid semver strings.
+The resulting output will always be 100% strict, of course.
+
+Strict-mode Comparators and Ranges will be strict about the SemVer
+strings that they parse.
+
+* `valid(v)`: Return the parsed version, or null if it's not valid.
+* `inc(v, release)`: Return the version incremented by the release
+  type (`major`,   `premajor`, `minor`, `preminor`, `patch`,
+  `prepatch`, or `prerelease`), or null if it's not valid
+  * `premajor` in one call will bump the version up to the next major
+    version and down to a prerelease of that major version.
+    `preminor`, and `prepatch` work the same way.
+  * If called from a non-prerelease version, the `prerelease` will work the
+    same as `prepatch`. It increments the patch version, then makes a
+    prerelease. If the input version is already a prerelease it simply
+    increments it.
+* `prerelease(v)`: Returns an array of prerelease components, or null
+  if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
+* `major(v)`: Return the major version number.
+* `minor(v)`: Return the minor version number.
+* `patch(v)`: Return the patch version number.
+* `intersects(r1, r2, loose)`: Return true if the two supplied ranges
+  or comparators intersect.
+
+### Comparison
+
+* `gt(v1, v2)`: `v1 > v2`
+* `gte(v1, v2)`: `v1 >= v2`
+* `lt(v1, v2)`: `v1 < v2`
+* `lte(v1, v2)`: `v1 <= v2`
+* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
+  even if they're not the exact same string.  You already know how to
+  compare strings.
+* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
+* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
+  the corresponding function above.  `"==="` and `"!=="` do simple
+  string comparison, but are included for completeness.  Throws if an
+  invalid comparison string is provided.
+* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
+  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
+* `rcompare(v1, v2)`: The reverse of compare.  Sorts an array of versions
+  in descending order when passed to `Array.sort()`.
+* `diff(v1, v2)`: Returns difference between two versions by the release type
+  (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
+  or null if the versions are the same.
+
+### Comparators
+
+* `intersects(comparator)`: Return true if the comparators intersect
+
+### Ranges
+
+* `validRange(range)`: Return the valid range or null if it's not valid
+* `satisfies(version, range)`: Return true if the version satisfies the
+  range.
+* `maxSatisfying(versions, range)`: Return the highest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minSatisfying(versions, range)`: Return the lowest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `gtr(version, range)`: Return `true` if version is greater than all the
+  versions possible in the range.
+* `ltr(version, range)`: Return `true` if version is less than all the
+  versions possible in the range.
+* `outside(version, range, hilo)`: Return true if the version is outside
+  the bounds of the range in either the high or low direction.  The
+  `hilo` argument must be either the string `'>'` or `'<'`.  (This is
+  the function called by `gtr` and `ltr`.)
+* `intersects(range)`: Return true if any of the ranges comparators intersect
+
+Note that, since ranges may be non-contiguous, a version might not be
+greater than a range, less than a range, *or* satisfy a range!  For
+example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
+until `2.0.0`, so the version `1.2.10` would not be greater than the
+range (because `2.0.1` satisfies, which is higher), nor less than the
+range (since `1.2.8` satisfies, which is lower), and it also does not
+satisfy the range.
+
+If you want to know if a version satisfies or does not satisfy a
+range, use the `satisfies(version, range)` function.

+The return value of the function is a function that will remove the
+handler.
+
+Note that the function *only* fires for signals if the signal would
+cause the proces to exit.  That is, there are no other listeners, and
+it is a fatal signal.
+
+## Options
+
+* `alwaysLast`: Run this handler after any other signal or exit
+  handlers.  This causes `process.emit` to be monkeypatched.

+# sprintf.js
+**sprintf.js** is a complete open source JavaScript sprintf implementation for the *browser* and *node.js*.
+
+Its prototype is simple:
+
+    string sprintf(string format , [mixed arg1 [, mixed arg2 [ ,...]]])
+
+The placeholders in the format string are marked by `%` and are followed by one or more of these elements, in this order:
+
+* An optional number followed by a `$` sign that selects which argument index to use for the value. If not specified, arguments will be placed in the same order as the placeholders in the input string.
+* An optional `+` sign that forces to preceed the result with a plus or minus sign on numeric values. By default, only the `-` sign is used on negative numbers.
+* An optional padding specifier that says what character to use for padding (if specified). Possible values are `0` or any other character precedeed by a `'` (single quote). The default is to pad with *spaces*.
+* An optional `-` sign, that causes sprintf to left-align the result of this placeholder. The default is to right-align the result.
+* An optional number, that says how many characters the result should have. If the value to be returned is shorter than this number, the result will be padded. When used with the `j` (JSON) type specifier, the padding length specifies the tab size used for indentation.
+* An optional precision modifier, consisting of a `.` (dot) followed by a number, that says how many digits should be displayed for floating point numbers. When used with the `g` type specifier, it specifies the number of significant digits. When used on a string, it causes the result to be truncated.
+* A type specifier that can be any of:
+    * `%` — yields a literal `%` character
+    * `b` — yields an integer as a binary number
+    * `c` — yields an integer as the character with that ASCII value
+    * `d` or `i` — yields an integer as a signed decimal number
+    * `e` — yields a float using scientific notation
+    * `u` — yields an integer as an unsigned decimal number
+    * `f` — yields a float as is; see notes on precision above
+    * `g` — yields a float as is; see notes on precision above
+    * `o` — yields an integer as an octal number
+    * `s` — yields a string as is
+    * `x` — yields an integer as a hexadecimal number (lower-case)
+    * `X` — yields an integer as a hexadecimal number (upper-case)
+    * `j` — yields a JavaScript object or array as a JSON encoded string
+
+## JavaScript `vsprintf`
+`vsprintf` is the same as `sprintf` except that it accepts an array of arguments, rather than a variable number of arguments:
+
+    vsprintf("The first 4 letters of the english alphabet are: %s, %s, %s and %s", ["a", "b", "c", "d"])
+
+## Argument swapping
+You can also swap the arguments. That is, the order of the placeholders doesn't have to match the order of the arguments. You can do that by simply indicating in the format string which arguments the placeholders refer to:
+
+    sprintf("%2$s %3$s a %1$s", "cracker", "Polly", "wants")
+And, of course, you can repeat the placeholders without having to increase the number of arguments.
+
+## Named arguments
+Format strings may contain replacement fields rather than positional placeholders. Instead of referring to a certain argument, you can now refer to a certain key within an object. Replacement fields are surrounded by rounded parentheses - `(` and `)` - and begin with a keyword that refers to a key:
+
+    var user = {
+        name: "Dolly"
+    }
+    sprintf("Hello %(name)s", user) // Hello Dolly
+Keywords in replacement fields can be optionally followed by any number of keywords or indexes:
+
+    var users = [
+        {name: "Dolly"},
+        {name: "Molly"},
+        {name: "Polly"}
+    ]
+    sprintf("Hello %(users[0].name)s, %(users[1].name)s and %(users[2].name)s", {users: users}) // Hello Dolly, Molly and Polly
+Note: mixing positional and named placeholders is not (yet) supported
+
+## Computed values
+You can pass in a function as a dynamic value and it will be invoked (with no arguments) in order to compute the value on-the-fly.
+
+    sprintf("Current timestamp: %d", Date.now) // Current timestamp: 1398005382890
+    sprintf("Current date and time: %s", function() { return new Date().toString() })
+
+# AngularJS
+You can now use `sprintf` and `vsprintf` (also aliased as `fmt` and `vfmt` respectively) in your AngularJS projects. See `demo/`.
+
+# Installation
+
+## Via Bower
+
+    bower install sprintf
+
+## Or as a node.js module
+
+    npm install sprintf-js
+
+### Usage
+
+    var sprintf = require("sprintf-js").sprintf,
+        vsprintf = require("sprintf-js").vsprintf
+
+    sprintf("%2$s %3$s a %1$s", "cracker", "Polly", "wants")
+    vsprintf("The first 4 letters of the english alphabet are: %s, %s, %s and %s", ["a", "b", "c", "d"])

+# state-toggle [![Build Status][travis-badge]][travis] [![Coverage Status][codecov-badge]][codecov]
+
+<!--lint disable heading-increment no-duplicate-headings-->
+
+Enter/exit a state.
+
+## Installation
+
+[npm][npm-install]:
+
+```bash
+npm install state-toggle
+```
+
+## Usage
+
+```javascript
+var toggle = require('state-toggle');
+var ctx = {on: false};
+var enter = toggle('on', ctx.on, ctx);
+var exit;
+
+// Entering:
+exit = enter();
+console.log(ctx.on); // true
+
+// Exiting:
+exit();
+console.log(ctx.on); // false
+```
+
+## API
+
+### `toggle(key, initial[, ctx])`
+
+Create a toggle, which when entering toggles `key` on `ctx` (or `this`,
+if `ctx` is not given) to `!initial`, and when exiting, sets `key` on
+the context back to the value it had before entering.
+
+###### Returns
+
+`Function` — [`enter`][enter].
+
+### `enter()`
+
+Enter the state.
+
+###### Context
+
+If no `ctx` was given to `toggle`, the context object (`this`) of `enter()`
+is used to toggle.
+
+###### Returns
+
+`Function` — [`exit`][exit].
+
+### `exit()`
+
+Exit the state, reverting `key` to the value it had before entering.

+# string-width [![Build Status](https://travis-ci.org/sindresorhus/string-width.svg?branch=master)](https://travis-ci.org/sindresorhus/string-width)
+
+> Get the visual width of a string - the number of columns required to display it
+
+Some Unicode characters are [fullwidth](https://en.wikipedia.org/wiki/Halfwidth_and_fullwidth_forms) and use double the normal width. [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code) are stripped and doesn't affect the width.
+
+Useful to be able to measure the actual width of command-line output.
+
+
+## Install
+
+```
+$ npm install string-width
+```
+
+
+## Usage
+
+```js
+const stringWidth = require('string-width');
+
+stringWidth('古');
+//=> 2
+
+stringWidth('\u001b[1m古\u001b[22m');
+//=> 2
+
+stringWidth('a');
+//=> 1
+```

+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v7.8.0/docs/api/).
+
+As of version 1.0.0 **string_decoder** uses semantic versioning.
+
+## Previous versions
+
+Previous version numbers match the versions found in Node core, e.g. 0.10.24 matches Node 0.10.24, likewise 0.11.10 matches Node 0.11.10.
+
+## Update
+
+The *build/* directory contains a build script that will scrape the source from the [nodejs/node](https://github.com/nodejs/node) repo given a specific Node version.

+
+## Install
+
+```
+$ npm install ansi-regex
+```
+
+
+## Usage
+
+```js
+const ansiRegex = require('ansi-regex');
+
+ansiRegex().test('\u001B[4mcake\u001B[0m');
+//=> true
+
+ansiRegex().test('cake');
+//=> false
+
+'\u001B[4mcake\u001B[0m'.match(ansiRegex());
+//=> ['\u001B[4m', '\u001B[0m']
+```
+
+
+## FAQ
+
+### Why do you test for codes not in the ECMA 48 standard?
+
+Some of the codes we run as a test are codes that we acquired finding various lists of non-standard or manufacturer specific codes. We test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them.
+
+On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out.

+# strip-json-comments [![Build Status](https://travis-ci.org/sindresorhus/strip-json-comments.svg?branch=master)](https://travis-ci.org/sindresorhus/strip-json-comments)
+
+> Strip comments from JSON. Lets you use comments in your JSON files!
+
+This is now possible:
+
+```js
+{
+	// rainbows
+	"unicorn": /* ❤ */ "cake"
+}
+```
+
+It will replace single-line comments `//` and multi-line comments `/**/` with whitespace. This allows JSON error positions to remain as close as possible to the original source.
+
+Also available as a [gulp](https://github.com/sindresorhus/gulp-strip-json-comments)/[grunt](https://github.com/sindresorhus/grunt-strip-json-comments)/[broccoli](https://github.com/sindresorhus/broccoli-strip-json-comments) plugin.
+
+
+## Install
+
+```
+$ npm install --save strip-json-comments
+```
+
+
+## Usage
+
+```js
+const json = '{/*rainbows*/"unicorn":"cake"}';
+
+JSON.parse(stripJsonComments(json));
+//=> {unicorn: 'cake'}
+```
+
+
+## API
+
+### stripJsonComments(input, [options])
+
+#### input
+
+Type: `string`
+
+Accepts a string with JSON and returns a string without comments.
+
+#### options
+
+##### whitespace
+
+Type: `boolean`  
+Default: `true`
+
+Replace comments with whitespace instead of stripping them entirely.

+
+if (supportsColor) {

+}
+```
+
+It obeys the `--color` and `--no-color` CLI flags.
+
+For situations where using `--color` is not possible, add an environment variable `FORCE_COLOR` with any value to force color. Trumps `--no-color`.

+#### Borderless Table
+
+Simply using "void" border character template creates a table with a lot of unnecessary spacing.
+
+To create a more plesant to the eye table, reset the padding and remove the joining rows, e.g.
+
+```js
+let output;
+
+output = table(data, {
+    border: getBorderCharacters(`void`),
+    columnDefault: {
+        paddingLeft: 0,
+        paddingRight: 1
+    },
+    drawJoin: () => {
+        return false
+    }
+});
+
+console.log(output);
+```
+
+```

+1A 1B 1C
+2A 2B 2C
+```
+
+<a name="table-usage-streaming"></a>
+### Streaming
+
+`table` package exports `createStream` function used to draw a table and append rows.
+
+`createStream` requires `{number} columnDefault.width` and `{number} columnCount` configuration properties.
+
+```js
+import {
+    createStream
+} from 'table';
+
+let config,
+    stream;
+
+config = {
+    columnDefault: {
+        width: 50
+    },
+    columnCount: 1
+};
+
+stream = createStream(config);
+
+setInterval(() => {
+    stream.write([new Date()]);
+}, 500);
+```
+
+![Streaming current date.](./.README/streaming.gif)
+
+`table` package uses ANSI escape codes to overwrite the output of the last line when a new row is printed.
+
+The underlying implementation is explained in this [Stack Overflow answer](http://stackoverflow.com/a/32938658/368691). 
+
+Streaming supports all of the configuration properties and functionality of a static table (such as auto text wrapping, alignment and padding), e.g.
+
+```js
+import {
+    createStream
+} from 'table';
+
+import _ from 'lodash';
+
+let config,
+    stream,
+    i;
+
+config = {
+    columnDefault: {
+        width: 50
+    },
+    columnCount: 3,
+    columns: {
+        0: {
+            width: 10,
+            alignment: 'right'
+        },
+        1: {
+            alignment: 'center',
+        },
+        2: {
+            width: 10
+        }
+    }
+};
+
+stream = createStream(config);
+
+i = 0;
+
+setInterval(() => {
+    let random;
+
+    random = _.sample('abcdefghijklmnopqrstuvwxyz', _.random(1, 30)).join('');
+
+    stream.write([i++, new Date(), random]);
+}, 500);
+```

+<a name="table-usage-text-truncation"></a>
+### Text Truncation
+
+To handle a content that overflows the container width, `table` package implements [text wrapping](#table-usage-text-wrapping). However, sometimes you may want to truncate content that is too long to be displayed in the table.
+
+`{number} config.columns[{number}].truncate` property (default: `Infinity`) truncates the text at the specified length.
+
+```js
+let config,
+    data,
+    output;
+
+data = [
+    ['Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus pulvinar nibh sed mauris convallis dapibus. Nunc venenatis tempus nulla sit amet viverra.']
+];
+
+config = {
+    columns: {
+        0: {
+            width: 20,
+            truncate: 100
+        }
+    }
+};
+
+output = table(data, config);
+
+console.log(output);
+```
+
+```
+╔══════════════════════╗
+║ Lorem ipsum dolor si ║
+║ t amet, consectetur  ║
+║ adipiscing elit. Pha ║
+║ sellus pulvinar nibh ║
+║ sed mauris conva...  ║
+╚══════════════════════╝
+```
+
+<a name="table-usage-text-wrapping"></a>
+### Text Wrapping
+
+`table` package implements auto text wrapping, i.e. text that has width greater than the container width will be separated into multiple lines, e.g.
+
+```js
+let config,
+    data,
+    output;
+
+data = [
+    ['Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus pulvinar nibh sed mauris convallis dapibus. Nunc venenatis tempus nulla sit amet viverra.']
+];
+
+config = {
+    columns: {
+        0: {
+            width: 20
+        }
+    }
+};
+
+output = table(data, config);
+
+console.log(output);
+```
+
+```
+╔══════════════════════╗
+║ Lorem ipsum dolor si ║
+║ t amet, consectetur  ║
+║ adipiscing elit. Pha ║
+║ sellus pulvinar nibh ║
+║ sed mauris convallis ║
+║ dapibus. Nunc venena ║
+║ tis tempus nulla sit ║
+║ amet viverra.        ║
+╚══════════════════════╝
+```
+
+When `wrapWord` is `true` the text is broken at the nearest space or one of the special characters ("-", "_", "\", "/", ".", ",", ";"), e.g.
+
+```js
+let config,
+    data,
+    output;
+
+data = [
+    ['Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus pulvinar nibh sed mauris convallis dapibus. Nunc venenatis tempus nulla sit amet viverra.']
+];
+
+config = {
+    columns: {
+        0: {
+            width: 20,
+            wrapWord: true
+        }
+    }
+};
+
+output = table(data, config);
+
+console.log(output);
+```

+    [ 'master', '0123456789abcdef' ],
+    [ 'staging', 'fedcba9876543210' ]

+
+```
+master   0123456789abcdef
+staging  fedcba9876543210
+```
+
+## left-right align
+
+``` js
+var table = require('text-table');
+var t = table([
+    [ 'beep', '1024' ],
+    [ 'boop', '33450' ],

+var t = table([
+    [ 'beep', '1024', 'xyz' ],
+    [ 'boop', '3388450', 'tuv' ],
+    [ 'foo', '10106', 'qrstuv' ],
+    [ 'bar', '45', 'lmno' ]
+], { align: [ 'l', 'c', 'l' ] });

+```
+
+# methods
+
+``` js
+var table = require('text-table')
+```
+
+## var s = table(rows, opts={})
+
+Return a formatted table string `s` from an array of `rows` and some options
+`opts`.
+
+`rows` should be an array of arrays containing strings, numbers, or other
+printable values.
+
+options can be:
+
+* `opts.hsep` - separator to use between columns, default `'  '`
+* `opts.align` - array of alignment types for each column, default `['l','l',...]`
+* `opts.stringLength` - callback function to use when calculating the string length
+
+alignment types are:
+
+* `'l'` - left
+* `'r'` - right
+* `'c'` - center
+* `'.'` - decimal
+
+# install
+
+With [npm](https://npmjs.org) do:
+
+```
+npm install text-table
+```
+
+# Use with ANSI-colors
+
+Since the string length of ANSI color schemes does not equal the length
+JavaScript sees internally it is necessary to pass the a custom string length
+calculator during the main function call.
+
+See the `test/ansi-colors.js` file for an example.

+[![build status](https://secure.travis-ci.org/dominictarr/through.png)](http://travis-ci.org/dominictarr/through)
+[![testling badge](https://ci.testling.com/dominictarr/through.png)](https://ci.testling.com/dominictarr/through)
+
+Easy way to create a `Stream` that is both `readable` and `writable`. 
+
+* Pass in optional `write` and `end` methods.
+* `through` takes care of pause/resume logic if you use `this.queue(data)` instead of `this.emit('data', data)`.
+* Use `this.pause()` and `this.resume()` to manage flow.
+* Check `this.paused` to see current flow state. (`write` always returns `!this.paused`).
+
+This function is the basis for most of the synchronous streams in 
+[event-stream](http://github.com/dominictarr/event-stream).
+
+``` js
+var through = require('through')
+
+through(function write(data) {
+    this.queue(data) //data *must* not be null
+  },
+  function end () { //optional
+    this.queue(null)
+  })
+```
+
+Or, can also be used _without_ buffering on pause, use `this.emit('data', data)`,
+and this.emit('end')
+
+``` js
+var through = require('through')
+
+through(function write(data) {
+    this.emit('data', data)
+    //this.pause() 
+  },
+  function end () { //optional
+    this.emit('end')
+  })
+```
+
+## Extended Options
+
+You will probably not need these 99% of the time.
+
+### autoDestroy=false
+
+By default, `through` emits close when the writable
+and readable side of the stream has ended.
+If that is not desired, set `autoDestroy=false`.
+
+``` js
+var through = require('through')
+
+//like this
+var ts = through(write, end, {autoDestroy: false})
+//or like this
+var ts = through(write, end)
+ts.autoDestroy = false
+```

+# trough [![Build Status][travis-badge]][travis] [![Coverage Status][codecov-badge]][codecov]
+
+> **trough** /trôf/ — a channel used to convey a liquid.
+
+`trough` is like [`ware`][ware] with less sugar, and middleware
+functions can change the input of the next.
+
+## Installation
+
+[npm][]:
+
+```bash
+npm install trough
+```
+
+## Usage
+
+```js
+var fs = require('fs');
+var path = require('path');
+var trough = require('trough');
+
+var pipeline = trough()
+  .use(function (fileName) {
+    console.log('Checking... ' + fileName);
+  })
+  .use(function (fileName) {
+    return path.join(process.cwd(), fileName);
+  })
+  .use(function (filePath, next) {
+    fs.stat(filePath, function (err, stats) {
+      next(err, {filePath: filePath, stats: stats});
+    });
+  })
+  .use(function (ctx, next) {
+    if (ctx.stats.isFile()) {
+      fs.readFile(ctx.filePath, next);
+    } else {
+      next(new Error('Expected file'));
+    }
+  });
+
+pipeline.run('readme.md', console.log);
+pipeline.run('node_modules', console.log);
+```
+
+Yields:
+
+```txt

+
+## API
+
+### `trough()`
+
+Create a new [`Trough`][trough].
+
+### `Trough`
+
+A pipeline.
+
+### `Trough#run([input..., ]done)`
+
+Run the pipeline (all [`use()`][use]d middleware).  Invokes [`done`][done]
+on completion with either an error or the output of the last middleware
+
+> Note! as the length of input defines whether [async][] function
+> get a `next` function, it’s recommended to keep `input` at one
+> value normally.
+
+#### `function done(err?, [output...])`
+
+The final handler passed to [`run()`][run], invoked with an error
+if a [middleware function][fn] rejected, passed, or threw one, or
+the output of the last middleware function.
+
+### `Trough#use(fn)`
+
+Add `fn`, a [middleware function][fn], to the pipeline.
+
+#### `function fn([input..., ][next])`
+
+A middleware function invoked with the output of its predecessor.
+
+##### Synchronous
+
+If `fn` returns or throws an error, the pipeline fails and `done` is
+invoked with that error.
+
+If `fn` returns a value (neither `null` nor `undefined`), the first
+`input` of the next function is set to that value (all other `input`
+is passed through).
+
+###### Example
+
+The following example shows how returning an error stops the pipeline:
+
+```js
+var trough = require('trough');
+
+trough()
+  .use(function (val) {
+    return new Error('Got: ' + val);
+  })
+  .run('some value', console.log);
+```
+
+Yields:
+
+```txt
+Error: Got: some value
+    at ~/example.js:5:12
+    ...
+```
+
+The following example shows how throwing an error stops the pipeline:
+
+```js
+var trough = require('trough');
+
+trough()
+  .use(function (val) {
+    throw new Error('Got: ' + val);
+  })
+  .run('more value', console.log);
+```
+
+Yields:
+
+```txt
+Error: Got: more value
+    at ~/example.js:5:11
+    ...
+```
+
+The following example shows how the first output can be modified:
+
+```js
+var trough = require('trough');
+
+trough()
+  .use(function (val) {
+    return 'even ' + val;
+  })
+  .run('more value', 'untouched', console.log);
+```
+
+Yields:
+
+```txt
+null 'even more value' 'untouched'
+```
+
+##### Promise
+
+If `fn` returns a promise, and that promise rejects, the pipeline fails
+and `done` is invoked with the rejected value.
+
+If `fn` returns a promise, and that promise resolves with a value
+(neither `null` nor `undefined`), the first `input` of the next function
+is set to that value (all other `input` is passed through).
+
+###### Example
+
+The following example shows how rejecting a promise stops the pipeline:
+
+```js
+var trough = require('trough');
+
+trough()
+  .use(function (val) {
+    return new Promise(function (resolve, reject) {
+      reject('Got: ' + val);
+    });
+  })
+  .run('val', console.log);
+```
+
+Yields:
+
+```txt
+Got: val
+```
+
+The following example shows how the input isn’t touched by resolving
+to `null`.
+
+```js
+var trough = require('trough');
+
+trough()
+  .use(function () {
+    return new Promise(function (resolve) {
+      setTimeout(function () {
+        resolve(null);
+      }, 100);
+    });
+  })
+  .run('Input', console.log);
+```
+
+Yields:
+
+```txt
+null 'Input'
+```
+
+##### Asynchronous
+
+If `fn` accepts one more argument than the given `input`, a `next`
+function is given (after the input).  `next` must be called, but doesn’t
+have to be called async.
+
+If `next` is given a value (neither `null` nor `undefined`) as its first
+argument, the pipeline fails and `done` is invoked with that value.
+
+If `next` is given no value (either `null` or `undefined`) as the first
+argument, all following non-nully values change the input of the following
+function, and all nully values default to the `input`.
+
+###### Example
+
+The following example shows how passing a first argument stops the
+pipeline:
+
+```js
+var trough = require('trough');
+
+trough()
+  .use(function (val, next) {
+    next(new Error('Got: ' + val));
+  })
+  .run('val', console.log);
+```
+
+Yields:
+
+```txt
+Error: Got: val
+    at ~/example.js:5:10
+```
+
+The following example shows how more values than the input are passed.
+
+```js
+var trough = require('trough');
+
+trough()
+  .use(function (val, next) {
+    setTimeout(function () {
+      next(null, null, 'values');
+    }, 100);
+  })
+  .run('some', console.log);
+```
+
+Yields:
+
+```txt
+null 'some' 'values'
+```

+# tryit
+
+Tiny module wrapping try/catch in JavaScript. 
+
+It's *literally 11 lines of code*, [just read it](tryit.js) that's all the documentation you'll need.
+
+
+## install
+
+```
+npm install tryit
+```
+
+## usage 
+
+What you'd normally do:
+```js
+try {
+    dangerousThing();
+} catch (e) {
+    console.log('something');
+}
+```
+
+With try-it (all it does is wrap try-catch)
+```js
+var tryit = require('tryit');
+
+tryit(dangerousThing);
+```
+
+You can also handle the error by passing a second function
+```js
+tryit(dangerousThing, function (e) {
+    if (e) {
+        console.log('do something');
+    }
+})
+```
+
+The second function follows error-first pattern common in node. So if you pass a callback it gets called in both cases. But will have an error as the first argument if it fails.
+
+## WHAT? WHY DO THIS!? 
+
+Primary motivation is having a clean way to wrap things that might fail, where I don't care if it fails. I just want to try it. 
+
+This includes stuff like blindly reading/parsing stuff from localStorage in the browser. If it's not there or if parsing it fails, that's fine. But I don't want to leave a bunch of empty `catch (e) {}` blocks in the code.
+
+Obviously, this is useful any time you're going to attempt to read some unknown data structure.
+
+In addition, my understanding is that it's hard for JS engines to optimize code in try blocks. By actually passing the code to be executed into a re-used try block, we can avoid having to have more than a single try block in our app. Again, this is not a primary motivation, just a potential side benefit.

+# type-check [![Build Status](https://travis-ci.org/gkz/type-check.png?branch=master)](https://travis-ci.org/gkz/type-check)
+
+<a name="type-check" />
+
+`type-check` is a library which allows you to check the types of JavaScript values at runtime with a Haskell like type syntax. It is great for checking external input, for testing, or even for adding a bit of safety to your internal code. It is a major component of [levn](https://github.com/gkz/levn). MIT license. Version 0.3.2. Check out the [demo](http://gkz.github.io/type-check/).
+
+For updates on `type-check`, [follow me on twitter](https://twitter.com/gkzahariev).
+
+    npm install type-check
+
+## Quick Examples
+
+```js
+// Basic types:
+var typeCheck = require('type-check').typeCheck;
+typeCheck('Number', 1);               // true
+typeCheck('Number', 'str');           // false
+typeCheck('Error', new Error);        // true
+typeCheck('Undefined', undefined);    // true
+
+// Comment
+typeCheck('count::Number', 1);        // true
+
+// One type OR another type:
+typeCheck('Number | String', 2);      // true
+typeCheck('Number | String', 'str');  // true
+
+// Wildcard, matches all types:
+typeCheck('*', 2) // true
+
+// Array, all elements of a single type:
+typeCheck('[Number]', [1, 2, 3]);                // true
+typeCheck('[Number]', [1, 'str', 3]);            // false
+
+// Tuples, or fixed length arrays with elements of different types:
+typeCheck('(String, Number)', ['str', 2]);       // true
+typeCheck('(String, Number)', ['str']);          // false
+typeCheck('(String, Number)', ['str', 2, 5]);    // false
+
+// Object properties:
+typeCheck('{x: Number, y: Boolean}', {x: 2, y: false});             // true
+typeCheck('{x: Number, y: Boolean}',       {x: 2});                 // false
+typeCheck('{x: Number, y: Maybe Boolean}', {x: 2});                 // true
+typeCheck('{x: Number, y: Boolean}',      {x: 2, y: false, z: 3});  // false
+typeCheck('{x: Number, y: Boolean, ...}', {x: 2, y: false, z: 3});  // true
+
+// A particular type AND object properties:
+typeCheck('RegExp{source: String, ...}', /re/i);          // true
+typeCheck('RegExp{source: String, ...}', {source: 're'}); // false
+
+// Custom types:
+var opt = {customTypes:
+  {Even: { typeOf: 'Number', validate: function(x) { return x % 2 === 0; }}}};
+typeCheck('Even', 2, opt); // true
+
+// Nested:
+var type = '{a: (String, [Number], {y: Array, ...}), b: Error{message: String, ...}}'
+typeCheck(type, {a: ['hi', [1, 2, 3], {y: [1, 'ms']}], b: new Error('oh no')}); // true
+```
+
+Check out the [type syntax format](#syntax) and [guide](#guide).
+
+## Usage
+
+`require('type-check');` returns an object that exposes four properties. `VERSION` is the current version of the library as a string. `typeCheck`, `parseType`, and `parsedTypeCheck` are functions.
+
+```js
+// typeCheck(type, input, options);
+typeCheck('Number', 2);               // true
+
+// parseType(type);
+var parsedType = parseType('Number'); // object
+
+// parsedTypeCheck(parsedType, input, options);
+parsedTypeCheck(parsedType, 2);       // true
+```
+
+### typeCheck(type, input, options)
+
+`typeCheck` checks a JavaScript value `input` against `type` written in the [type format](#type-format) (and taking account the optional `options`) and returns whether the `input` matches the `type`.
+
+##### arguments
+* type - `String` - the type written in the [type format](#type-format) which to check against
+* input - `*` - any JavaScript value, which is to be checked against the type
+* options - `Maybe Object` - an optional parameter specifying additional options, currently the only available option is specifying [custom types](#custom-types)
+
+##### returns
+`Boolean` - whether the input matches the type
+
+##### example
+```js
+typeCheck('Number', 2); // true
+```
+
+### parseType(type)
+
+`parseType` parses string `type` written in the [type format](#type-format) into an object representing the parsed type.
+
+##### arguments
+* type - `String` - the type written in the [type format](#type-format) which to parse
+
+##### returns
+`Object` - an object in the parsed type format representing the parsed type
+
+##### example
+```js
+parseType('Number'); // [{type: 'Number'}]
+```
+### parsedTypeCheck(parsedType, input, options)
+
+`parsedTypeCheck` checks a JavaScript value `input` against parsed `type` in the parsed type format (and taking account the optional `options`) and returns whether the `input` matches the `type`. Use this in conjunction with `parseType` if you are going to use a type more than once.
+
+##### arguments
+* type - `Object` - the type in the parsed type format which to check against
+* input - `*` - any JavaScript value, which is to be checked against the type
+* options - `Maybe Object` - an optional parameter specifying additional options, currently the only available option is specifying [custom types](#custom-types)
+
+##### returns
+`Boolean` - whether the input matches the type
+
+##### example
+```js
+parsedTypeCheck([{type: 'Number'}], 2); // true
+var parsedType = parseType('String');
+parsedTypeCheck(parsedType, 'str');     // true
+```
+
+<a name="type-format" />
+## Type Format
+
+### Syntax
+
+White space is ignored. The root node is a __Types__.

+
+### Guide
+
+`type-check` uses `Object.toString` to find out the basic type of a value. Specifically,
+
+```js
+{}.toString.call(VALUE).slice(8, -1)
+{}.toString.call(true).slice(8, -1) // 'Boolean'
+```
+A basic type, eg. `Number`, uses this check. This is much more versatile than using `typeof` - for example, with `document`, `typeof` produces `'object'` which isn't that useful, and our technique produces `'HTMLDocument'`.
+
+You may check for multiple types by separating types with a `|`. The checker proceeds from left to right, and passes if the value is any of the types - eg. `String | Boolean` first checks if the value is a string, and then if it is a boolean. If it is none of those, then it returns false.
+
+Adding a `Maybe` in front of a list of multiple types is the same as also checking for `Null` and `Undefined` - eg. `Maybe String` is equivalent to `Undefined | Null | String`.
+
+You may add a comment to remind you of what the type is for by following an identifier with a `::` before a type (or multiple types). The comment is simply thrown out.
+
+The wildcard `*` matches all types.
+
+There are three types of structures for checking the contents of a value: 'fields', 'tuple', and 'array'.
+
+If used by itself, a 'fields' structure will pass with any type of object as long as it is an instance of `Object` and the properties pass - this allows for duck typing - eg. `{x: Boolean}`.
+
+To check if the properties pass, and the value is of a certain type, you can specify the type - eg. `Error{message: String}`.
+
+If you want to make a field optional, you can simply use `Maybe` - eg. `{x: Boolean, y: Maybe String}` will still pass if `y` is undefined (or null).
+
+If you don't care if the value has properties beyond what you have specified, you can use the 'etc' operator `...` - eg. `{x: Boolean, ...}` will match an object with an `x` property that is a boolean, and with zero or more other properties.
+
+For an array, you must specify one or more types (separated by `|`) - it will pass for something of any length as long as each element passes the types provided - eg. `[Number]`, `[Number | String]`.
+
+A tuple checks for a fixed number of elements, each of a potentially different type. Each element is separated by a comma - eg. `(String, Number)`.
+
+An array and tuple structure check that the value is of type `Array` by default, but if another type is specified, they will check for that instead - eg. `Int32Array[Number]`. You can use the wildcard `*` to search for any type at all.
+
+Check out the [type precedence](https://github.com/zaboco/type-precedence) library for type-check.
+
+## Options
+
+Options is an object. It is an optional parameter to the `typeCheck` and `parsedTypeCheck` functions. The only current option is `customTypes`.
+
+<a name="custom-types" />
+### Custom Types
+
+__Example:__
+
+```js
+var options = {
+  customTypes: {
+    Even: {
+      typeOf: 'Number',
+      validate: function(x) {
+        return x % 2 === 0;
+      }
+    }
+  }
+};
+typeCheck('Even', 2, options); // true
+typeCheck('Even', 3, options); // false
+```
+
+`customTypes` allows you to set up custom types for validation. The value of this is an object. The keys of the object are the types you will be matching. Each value of the object will be an object having a `typeOf` property - a string, and `validate` property - a function.
+
+The `typeOf` property is the type the value should be, and `validate` is a function which should return true if the value is of that type. `validate` receives one parameter, which is the value that we are checking.
+
+## Technical About
+
+`type-check` is written in [LiveScript](http://livescript.net/) - a language that compiles to JavaScript. It also uses the [prelude.ls](http://preludels.com/) library.

+## Installation
+
+[npm][npm-install]:
+
+```bash
+npm install unherit
+```
+
+## Usage
+
+```js
+var EventEmitter = require('events').EventEmitter;
+
+/* Create a private class which acts just like
+ * `EventEmitter`. */
+var Emitter = unherit(EventEmitter);
+
+Emitter.prototype.defaultMaxListeners = 0;
+/* Now, all instances of `Emitter` have no maximum
+ * listeners, without affecting other `EventEmitter`s. */
+
+assert(new Emitter().defaultMaxListeners === 0); // true
+assert(new EventEmitter().defaultMaxListeners === undefined); // true
+assert(new Emitter() instanceof EventEmitter); // true
+```
+
+## API
+
+### `unherit(Super)`
+
+Create a custom constructor which can be modified without affecting the
+original class.
+
+###### Parameters
+
+*   `Super` (`Function`) — Super-class.
+
+###### Returns
+
+`Function` — Constructor acting like `Super`, which can be modified
+without affecting the original class.

+
+**unified** is an interface for processing text using syntax trees.  It’s what
+powers [**remark**][remark], [**retext**][retext], and [**rehype**][rehype],
+but it also allows for processing between multiple syntaxes.
+
+The website for **unified**, [`unifiedjs.github.io`][site], provides a less
+technical and more practical introduction to unified.  Make sure to visit it
+and try its introductory [Guides][].
+
+## Installation
+
+[npm][]:
+
+```bash
+npm install unified
+```
+
+## Usage
+
+```js
+var unified = require('unified');
+var markdown = require('remark-parse');
+var remark2rehype = require('remark-rehype');
+var doc = require('rehype-document');
+var format = require('rehype-format');
+var html = require('rehype-stringify');
+var report = require('vfile-reporter');
+
+unified()
+  .use(markdown)
+  .use(remark2rehype)
+  .use(doc)
+  .use(format)
+  .use(html)
+  .process('# Hello world!', function (err, file) {
+    console.error(report(err || file));
+    console.log(String(file));
+  });
+```
+
+Yields:
+
+```html
+no issues found
+<!DOCTYPE html>
+<html lang="en">
+  <head>
+    <meta charset="utf-8">
+    <meta name="viewport" content="width=device-width, initial-scale=1">
+  </head>
+  <body>
+    <h1>Hello world!</h1>
+  </body>
+</html>

+## Description
+
+**unified** is an interface for processing text using syntax trees.  Syntax
+trees are a representation understandable to programs.  Those programs, called
+[**plugin**][plugin]s, take these trees and modify them, amongst other things.
+To get to the syntax tree from input text there’s a [**parser**][parser].  To
+get from that back to text there’s a [**compiler**][compiler].  This is the
+[**process**][process] of a **processor**.
+
+```ascii
+| ....................... process() ......................... |
+| ......... parse() ..... | run() | ..... stringify() ....... |
+
+          +--------+                     +----------+
+Input ->- | Parser | ->- Syntax Tree ->- | Compiler | ->- Output
+          +--------+          |          +----------+
+                              X
+                              |
+                       +--------------+
+                       | Transformers |
+                       +--------------+
+```
+
+###### Processors
+
+Every processor implements another processor.  To create a new processor invoke
+another processor.  This creates a processor that is configured to function the
+same as its ancestor.  But when the descendant processor is configured in the
+future it does not affect the ancestral processor.
+
+When processors are exposed from a module (for example, unified itself) they
+should not be configured directly, as that would change their behaviour for all
+module users.  Those processors are [**frozen**][freeze] and they should be
+invoked to create a new processor before they are used.
+
+###### Node
+
+The syntax trees used in **unified** are [**Unist**][unist] nodes: plain
+JavaScript objects with a `type` property.  The semantics of those `type`s are
+defined by other projects.
+
+There are several [utilities][unist-utilities] for working with these nodes.
+
+###### List of Processors
+
+The following projects process different syntax trees.  They parse text to
+their respective syntax tree and they compile their syntax trees back to text.
+These processors can be used as-is, or their parsers and compilers can be mixed
+and matched with **unified** and other plugins to process between different
+syntaxes.
+
+*   [**rehype**][rehype] ([**HAST**][hast]) — HTML
+*   [**remark**][remark] ([**MDAST**][mdast]) — Markdown
+*   [**retext**][retext] ([**NLCST**][nlcst]) — Natural language
+
+###### List of Plugins
+
+The below plugins work with **unified**, unrelated to what flavour the syntax
+tree is in:
+
+*   [`unified-diff`](https://github.com/unifiedjs/unified-diff)
+    — Ignore messages for unchanged lines in Travis
+
+See [**remark**][remark-plugins], [**rehype**][rehype-plugins], and
+[**retext**][retext-plugins] for lists of their plugins.
+
+###### File
+
+When processing documents metadata is often gathered about that document.
+[**VFile**][vfile] is a virtual file format which stores data and handles
+metadata and messages for **unified** and its plugins.
+
+There are several [utilities][vfile-utilities] for working with these files.
+
+###### Configuration
+
+To configure a processor invoke its [`use`][use] method, supply it a
+[**plugin**][plugin], and optionally settings.
+
+###### Integrations
+
+**unified** can integrate with the file-system through
+[`unified-engine`][engine].  On top of that, CLI apps can be created with
+[`unified-args`][args], Gulp plugins with [`unified-engine-gulp`][gulp], and
+Atom Linters with [`unified-engine-atom`][atom].
+
+A streaming interface is provided through [`unified-stream`][stream].
+
+###### Programming interface
+
+The API gives access to processing metadata (such as lint messages) and
+supports multiple passed through files:
+
+```js
+var unified = require('unified');
+var markdown = require('remark-parse');
+var styleGuide = require('remark-preset-lint-markdown-style-guide');
+var remark2retext = require('remark-retext');
+var english = require('retext-english');
+var equality = require('retext-equality');
+var remark2rehype = require('remark-rehype');
+var html = require('rehype-stringify');
+var report = require('vfile-reporter');
+
+unified()
+  .use(markdown)
+  .use(styleGuide)

+
+###### Processing between syntaxes
+
+The processors can be combined in two modes.
+
+**Bridge** mode transforms the syntax tree from one flavour (the origin) to
+another (the destination).  Then, transformations are applied on that tree.
+Finally, the origin processor continues transforming the original syntax tree.
+
+**Mutate** mode also transforms the syntax tree from one flavour to another.
+But then the origin processor continues transforming the destination syntax
+tree.
+
+In the previous example (“Programming interface”), `remark-retext` is used in
+bridge mode: the origin syntax tree is kept after retext is done; whereas
+`remark-rehype` is used in mutate mode: it sets a new syntax tree and discards
+the original.
+

+
+## API
+
+### `processor()`
+
+Object describing how to process text.
+
+###### Returns
+
+`Function` — New [**unfrozen**][freeze] processor which is configured to
+function the same as its ancestor.  But when the descendant processor is
+configured in the future it does not affect the ancestral processor.
+
+###### Example
+
+The following example shows how a new processor can be created (from the remark
+processor) and linked to **stdin**(4) and **stdout**(4).
+
+```js
+var remark = require('remark');
+var concat = require('concat-stream');
+
+process.stdin.pipe(concat(function (buf) {
+  process.stdout.write(remark().processSync(buf).toString());
+}));
+```
+
+### `processor.use(plugin[, options])`
+
+Configure the processor to use a [**plugin**][plugin] and optionally configure
+that plugin with options.
+
+###### Signatures
+
+*   `processor.use(plugin[, options])`
+*   `processor.use(preset)`
+*   `processor.use(list)`
+
+###### Parameters
+
+*   `plugin` ([`Plugin`][plugin])
+*   `options` (`*`, optional) — Configuration for `plugin`
+*   `preset` (`Object`) — Object with an optional `plugins` (set to `list`),
+    and/or an optional `settings` object
+*   `list` (`Array`) — List of plugins, presets, and pairs (`plugin` and
+    `options` in an array)
+
+###### Returns
+
+`processor` — The processor on which `use` is invoked.
+
+###### Note
+
+`use` cannot be called on [frozen][freeze] processors.  Invoke the processor
+first to create a new unfrozen processor.
+
+###### Example
+
+There are many ways to pass plugins to `.use()`.  The below example gives an
+overview.
+
+```js
+var unified = require('unified');
+
+unified()
+  // Plugin with options:
+  .use(plugin, {})
+  // Plugins:
+  .use([plugin, pluginB])
+  // Two plugins, the second with options:
+  .use([plugin, [pluginB, {}]])
+  // Preset with plugins and settings:
+  .use({plugins: [plugin, [pluginB, {}]], settings: {position: false}})
+  // Settings only:
+  .use({settings: {position: false}});
+
+function plugin() {}
+function pluginB() {}
+```
+
+### `processor.parse(file|value)`
+
+Parse text to a syntax tree.
+
+###### Parameters
+
+*   `file` ([`VFile`][file])
+    — Or anything which can be given to `vfile()`
+
+###### Returns
+
+[`Node`][node] — Syntax tree representation of input.
+
+###### Note
+
+`parse` [freezes][freeze] the processor if not already frozen.
+
+#### `processor.Parser`
+
+Function handling the parsing of text to a syntax tree.  Used in the
+[**parse**][parse] phase in the process and invoked with a `string` and
+[`VFile`][file] representation of the document to parse.
+
+`Parser` can be a normal function in which case it must return a
+[`Node`][node]: the syntax tree representation of the given file.
+
+`Parser` can also be a constructor function (a function with keys in its
+`prototype`) in which case it’s invoked with `new`.  Instances must have a
+`parse` method which is invoked without arguments and must return a
+[`Node`][node].
+
+### `processor.stringify(node[, file])`
+
+Compile a syntax tree to text.
+
+###### Parameters
+
+*   `node` ([`Node`][node])
+*   `file` ([`VFile`][file], optional);
+    — Or anything which can be given to `vfile()`
+
+###### Returns
+
+`string` — String representation of the syntax tree file.
+
+###### Note
+
+`stringify` [freezes][freeze] the processor if not already frozen.
+
+#### `processor.Compiler`
+
+Function handling the compilation of syntax tree to a text.  Used in the
+[**stringify**][stringify] phase in the process and invoked with a
+[`Node`][node] and [`VFile`][file] representation of the document to stringify.
+
+`Compiler` can be a normal function in which case it must return a `string`:
+the text representation of the given syntax tree.
+
+`Compiler` can also be a constructor function (a function with keys in its
+`prototype`) in which case it’s invoked with `new`.  Instances must have a
+`compile` method which is invoked without arguments and must return a `string`.
+
+### `processor.run(node[, file][, done])`
+
+Transform a syntax tree by applying [**plugin**][plugin]s to it.
+
+###### Parameters
+
+*   `node` ([`Node`][node])
+*   `file` ([`VFile`][file], optional)
+    — Or anything which can be given to `vfile()`
+*   `done` ([`Function`][run-done], optional)
+
+###### Returns
+
+[`Promise`][promise] if `done` is not given.  Rejected with an error, or
+resolved with the resulting syntax tree.
+
+###### Note
+
+`run` [freezes][freeze] the processor if not already frozen.
+
+##### `function done(err[, node, file])`
+
+Invoked when transformation is complete.  Either invoked with an error or a
+syntax tree and a file.
+
+###### Parameters
+
+*   `err` (`Error`) — Fatal error

+*   `file` ([`VFile`][file])
+
+### `processor.runSync(node[, file])`
+
+Transform a syntax tree by applying [**plugin**][plugin]s to it.

+If asynchronous [**plugin**][plugin]s are configured an error is thrown.
+
+###### Parameters
+
+*   `node` ([`Node`][node])
+*   `file` ([`VFile`][file], optional)
+    — Or anything which can be given to `vfile()`
+
+###### Returns
+
+[`Node`][node] — The given syntax tree.
+
+###### Note
+
+`runSync` [freezes][freeze] the processor if not already frozen.
+
+### `processor.process(file|value[, done])`
+
+Process the given representation of a file as configured on the processor.  The
+process invokes `parse`, `run`, and `stringify` internally.
+
+###### Parameters
+
+*   `file` ([`VFile`][file])
+*   `value` (`string`) — String representation of a file
+*   `done` ([`Function`][process-done], optional)

+
+[`Promise`][promise] if `done` is not given.  Rejected with an error or
+resolved with the resulting file.
+
+###### Note
+
+`process` [freezes][freeze] the processor if not already frozen.
+
+#### `function done(err, file)`
+
+Invoked when the process is complete.  Invoked with a fatal error, if any, and
+the [`VFile`][file].
+
+###### Parameters
+
+*   `err` (`Error`, optional) — Fatal error

+  .use(remark2rehype)
+  .use(doc)
+  .use(format)
+  .use(html)
+  .process('# Hello world!')
+  .then(function (file) {
+    console.log(String(file));
+  }, function (err) {
+    console.error(String(err));
+  });
+```
+
+Yields:
+
+```html
+<!DOCTYPE html>
+<html lang="en">
+  <head>
+    <meta charset="utf-8">
+    <meta name="viewport" content="width=device-width, initial-scale=1">
+  </head>
+  <body>
+    <h1>Hello world!</h1>
+  </body>
+</html>
+```
+
+### `processor.processSync(file|value)`
+
+Process the given representation of a file as configured on the processor.  The
+process invokes `parse`, `run`, and `stringify` internally.
+
+If asynchronous [**plugin**][plugin]s are configured an error is thrown.
+
+###### Parameters
+
+*   `file` ([`VFile`][file])
+*   `value` (`string`) — String representation of a file
+
+###### Returns
+
+[`VFile`][file] — Virtual file with modified [`contents`][vfile-contents].
+
+###### Note
+
+`processSync` [freezes][freeze] the processor if not already frozen.
+
+###### Example
+
+```js
+var unified = require('unified');
+var markdown = require('remark-parse');
+var remark2rehype = require('remark-rehype');
+var doc = require('rehype-document');
+var format = require('rehype-format');
+var html = require('rehype-stringify');
+
+var processor = unified()
+  .use(markdown)
+  .use(remark2rehype)
+  .use(doc)
+  .use(format)
+  .use(html);
+
+console.log(processor.processSync('# Hello world!').toString());
+```
+
+Yields:
+
+```html
+<!DOCTYPE html>
+<html lang="en">
+  <head>
+    <meta charset="utf-8">
+    <meta name="viewport" content="width=device-width, initial-scale=1">
+  </head>
+  <body>
+    <h1>Hello world!</h1>
+  </body>
+</html>
+```
+
+### `processor.data(key[, value])`
+
+Get or set information in an in-memory key-value store accessible to all phases
+of the process.  An example is a list of HTML elements which are self-closing,
+which is needed when parsing, transforming, and compiling HTML.
+
+###### Parameters
+
+*   `key` (`string`) — Identifier
+*   `value` (`*`, optional) — Value to set.  Omit if getting `key`
+
+###### Returns
+
+*   `processor` — If setting, the processor on which `data` is invoked
+*   `*` — If getting, the value at `key`
+
+###### Note
+
+Setting information with `data` cannot occur on [frozen][freeze] processors.
+Invoke the processor first to create a new unfrozen processor.
+
+###### Example
+
+The following example show how to get and set information:
+
+```js
+var unified = require('unified');
+
+console.log(unified().data('alpha', 'bravo').data('alpha'))
+```
+
+Yields:
+
+```txt
+bravo
+```
+
+### `processor.freeze()`
+
+Freeze a processor.  Frozen processors are meant to be extended and not to be
+configured or processed directly.
+
+Once a processor is frozen it cannot be unfrozen.  New processors functioning
+just like it can be created by invoking the processor.
+
+It’s possible to freeze processors explicitly, by calling `.freeze()`, but
+[`.parse()`][parse], [`.run()`][run], [`.stringify()`][stringify], and
+[`.process()`][process] call `.freeze()` to freeze a processor too.
+
+###### Returns
+
+`Processor` — The processor on which `freeze` is invoked.
+
+###### Example
+
+The following example, `index.js`, shows how [**rehype**][rehype] prevents
+extensions to itself:
+
+```js
+var unified = require('unified');
+var parse = require('rehype-parse');
+var stringify = require('rehype-stringify');
+
+module.exports = unified().use(parse).use(stringify).freeze();
+```
+
+The below example, `a.js`, shows how that processor can be used and configured.
+
+```js
+var rehype = require('rehype');
+var format = require('rehype-format');
+// ...
+
+rehype()
+  .use(format)
+  // ...
+```
+
+The below example, `b.js`, shows a similar looking example which operates on
+the frozen [**rehype**][rehype] interface.  If this behaviour was allowed it
+would result in unexpected behaviour so an error is thrown.  **This is
+invalid**:
+
+```js
+var rehype = require('rehype');
+var format = require('rehype-format');
+// ...
+
+rehype
+  .use(format)
+  // ...
+```
+
+Yields:
+
+```txt
+~/node_modules/unified/index.js:440
+    throw new Error(
+    ^
+
+Error: Cannot invoke `use` on a frozen processor.
+Create a new processor first, by invoking it: use `processor()` instead of `processor`.
+    at assertUnfrozen (~/node_modules/unified/index.js:440:11)
+    at Function.use (~/node_modules/unified/index.js:172:5)
+    at Object.<anonymous> (~/b.js:6:4)
+```
+
+## `Plugin`
+
+**unified** plugins change the way the applied-on processor works in the
+following ways:
+
+*   They modify the [**processor**][processor]: such as changing the parser,
+    the compiler, or linking it to other processors
+*   They transform [**syntax tree**][node] representation of files
+*   They modify metadata of files
+
+Plugins are a concept.  They materialise as [`attacher`][attacher]s.
+
+###### Example
+
+`move.js`:
+
+```js
+module.exports = move;
+
+function move(options) {
+  var expected = (options || {}).extname;
+
+  if (!expected) {
+    throw new Error('Missing `extname` in options');
+  }
+
+  return transformer;
+
+  function transformer(tree, file) {
+    if (file.extname && file.extname !== expected) {
+      file.extname = expected;
+    }
+  }
+}
+```
+
+`index.js`:
+
+```js
+var unified = require('unified');
+var parse = require('remark-parse');
+var remark2rehype = require('remark-rehype');
+var stringify = require('rehype-stringify');
+var vfile = require('to-vfile');
+var report = require('vfile-reporter');
+var move = require('./move');
+
+unified()
+  .use(parse)
+  .use(remark2rehype)
+  .use(move, {extname: '.html'})
+  .use(stringify)
+  .process(vfile.readSync('index.md'), function (err, file) {
+    console.error(report(err || file));
+    if (file) {
+      vfile.writeSync(file); // Written to `index.html`.
+    }
+  });
+```
+
+### `function attacher([options])`
+
+An attacher is the thing passed to [`use`][use].  It configures the processor
+and in turn can receive options.
+
+Attachers can configure processors, such as by interacting with parsers and
+compilers, linking them to other processors, or by specifying how the syntax
+tree is handled.
+
+###### Context
+
+The context object is set to the invoked on [`processor`][processor].
+
+###### Parameters
+
+*   `options` (`*`, optional) — Configuration
+
+###### Returns
+
+[`transformer`][transformer] — Optional.
+
+###### Note
+
+Attachers are invoked when the processor is [frozen][freeze]: either when
+`.freeze()` is called explicitly, or when [`.parse()`][parse], [`.run()`][run],
+[`.stringify()`][stringify], or [`.process()`][process] is called for the first
+time.
+
+### `function transformer(node, file[, next])`
+
+Transformers modify the syntax tree or metadata of a file.  A transformer is a
+function which is invoked each time a file is passed through the transform
+phase.  If an error occurs (either because it’s thrown, returned, rejected, or
+passed to [`next`][next]), the process stops.
+
+The transformation process in **unified** is handled by [`trough`][trough], see
+it’s documentation for the exact semantics of transformers.
+
+###### Parameters
+
+*   `node` ([`Node`][node])
+*   `file` ([`VFile`][file])
+*   `next` ([`Function`][next], optional)
+
+###### Returns
+
+*   `Error` — Can be returned to stop the process
+*   [`Node`][node] — Can be returned and results in further transformations
+    and `stringify`s to be performed on the new tree
+*   `Promise` — If a promise is returned, the function is asynchronous, and
+    **must** be resolved (optionally with a [`Node`][node]) or rejected
+    (optionally with an `Error`)
+
+#### `function next(err[, tree[, file]])`
+
+If the signature of a transformer includes `next` (third argument), the
+function **may** finish asynchronous, and **must** invoke `next()`.
+
+###### Parameters
+
+*   `err` (`Error`, optional) — Stop the process
+*   `node` ([`Node`][node], optional) — New syntax tree
+*   `file` ([`VFile`][file], optional) — New virtual file
+
+## `Preset`
+
+Presets provide a potentially sharable way to configure processors.  They can
+contain multiple plugins and optionally settings as well.
+
+###### Example
+
+`preset.js`:
+
+```js
+exports.settings = {bullet: '*', fences: true};
+
+exports.plugins = [
+  require('remark-preset-lint-recommended'),
+  require('remark-comment-config'),
+  require('remark-preset-lint-markdown-style-guide'),
+  [require('remark-toc'), {maxDepth: 3, tight: true}],
+  require('remark-github')
+];
+```
+
+`index.js`:
+
+```js
+var remark = require('remark');
+var vfile = require('to-vfile');
+var report = require('vfile-reporter');
+var preset = require('./preset');
+
+remark()
+  .use(preset)
+  .process(vfile.readSync('index.md'), function (err, file) {
+    console.error(report(err || file));
+
+    if (file) {
+      vfile.writeSync(file);
+    }
+  });
+```

+# unist-util-is [![Build Status][travis-badge]][travis] [![Coverage Status][codecov-badge]][codecov]
+
+[**Unist**][unist] utility to check if a node passes a test.
+
+## Installation
+
+[npm][]:
+
+```bash
+npm install unist-util-is
+```
+
+## Usage
+
+```js
+var is = require('unist-util-is');
+
+var node = {type: 'strong'};
+var parent = {type: 'paragraph', children: [node]};
+
+function test(node, n) { return n === 5 }
+
+is(); // false
+is(null, {children: []}); // false
+is(null, node); // true
+is('strong', node); // true
+is('emphasis', node); // false
+
+is(node, node) // true
+is({type: 'paragraph'}, parent) // true
+is({type: 'strong'}, parent) // false
+
+is(test, node); // false
+is(test, node, 4, parent); // false
+is(test, node, 5, parent); // true
+```
+
+## API
+
+### `is(test, node[, index, parent[, context]])`
+
+###### Parameters
+
+*   `test` ([`Function`][test], `string`, `Object`, or `Array.<Test>`, optional)
+    —  When not given, checks if `node` is a [`Node`][node].
+    When `string`, works like passing `function (node) {return
+    node.type === test}`.
+    When `array`, checks any one of the subtests pass.
+    When `object`, checks that all keys in `test` are in `node`,
+    and that they have (strictly) equal values
+*   `node` ([`Node`][node]) — Node to check.  `false` is returned
+*   `index` (`number`, optional) — Position of `node` in `parent`
+*   `parent` (`Node`, optional) — Parent of `node`
+*   `context` (`*`, optional) — Context object to invoke `test` with
+
+###### Returns
+
+`boolean` — Whether `test` passed _and_ `node` is a [`Node`][node] (object
+with `type` set to non-empty `string`).
+
+#### `function test(node[, index, parent])`
+
+###### Parameters
+
+*   `node` (`Node`) — Node to test
+*   `index` (`number?`) — Position of `node` in `parent`
+*   `parent` (`Node?`) — Parent of `node`
+
+###### Context
+
+`*` — The to `is` given `context`.
+
+###### Returns
+
+`boolean?` — Whether `node` matches.

+# unist-util-stringify-position [![Build Status][build-badge]][build-page] [![Coverage Status][coverage-badge]][coverage-page]
+
+Stringify a [**Unist**][unist] [position][] or [location][].
+
+## Installation
+
+[npm][]:
+
+```bash
+npm install unist-util-stringify-position
+```
+
+## Usage
+
+```javascript
+var stringify = require('unist-util-stringify-position');
+
+stringify({line: 2, column: 3 }); //=> '2:3'
+
+stringify({
+  start: {line: 2},
+  end: {line: 3}
+}); //=> '2:1-3:1'
+
+stringify({
+  type: 'text',
+  value: '!',
+  position: {
+    start: {line: 5, column: 11},
+    end: {line: 5, column: 12}
+  }
+}); //=> '5:11-5:12'
+```
+
+## API
+
+### `stringifyPosition(node|location|position)`
+
+Stringify one position, a location (start and end positions), or
+a node’s location.
+
+###### Parameters
+
+*   `node` ([`Node`][node])
+    — Node whose `'position'` property to stringify
+*   `location` ([`Location`][location])
+    — Location whose `'start'` and `'end'` positions to stringify
+*   `position` ([`Position`][position])
+    — Location whose `'line'` and `'column'` to stringify
+
+###### Returns
+
+`string?` — A range `ls:cs-le:ce` (when given `node` or
+`location`) or a point `l:c` (when given `position`), where `l` stands
+for line, `c` for column, `s` for `start`, and `e` for
+end.  `null` is returned if the given value is neither `node`,
+`location`, nor `position`.

+
+[Unist][] node visitor.  Useful when working with [**remark**][remark],
+[**retext**][retext], or [**rehype**][rehype].
+
+## Installation
+
+[npm][]:
+
+```bash
+npm install unist-util-visit
+```
+
+## Usage
+
+```javascript
+var remark = require('remark');
+var visit = require('unist-util-visit');
+
+var tree = remark.parse('Some _emphasis_, **importance**, and `code`.');
+
+visit(tree, 'text', visitor);
+
+function visitor(node) {
+  console.log(node);
+}
+```
+
+Yields:
+
+```js
+{ type: 'text', value: 'Some ' }
+{ type: 'text', value: 'emphasis' }
+{ type: 'text', value: ', ' }
+{ type: 'text', value: 'importance' }
+{ type: 'text', value: ', and ' }
+{ type: 'text', value: '.' }
+```
+
+## API
+
+### `visit(node[, test], visitor[, reverse])`
+
+Visit nodes.  Optionally filtering nodes.  Optionally in reverse.
+
+###### Parameters
+
+*   `node` ([`Node`][node])
+    — Node to search
+*   `test` ([`Test`][is], optional)
+    — Node type or other [`is`][is]-compatible test
+*   `visitor` ([Function][visitor])
+    — Visitor invoked when a node is found
+*   `reverse` (`boolean`, default: `false`)
+    — When falsey, checking starts at the first child and continues
+    through to later children.  When truthy, this is reversed.
+    This **does not** mean checking starts at the deepest node and
+    continues on to the highest node
+
+#### `stop? = visitor(node, index, parent)`
+
+Invoked when a node (matching `test`, if given) is found.
+
+###### Parameters
+
+*   `node` (`Node`) — Found node
+*   `index` (`number?`) — Position of `node` in `parent`
+*   `parent` (`Node?`) — Parent of `node`
+
+###### Returns
+
+`boolean?` - When `false`, visiting is immediately stopped.
+
+## Related
+
+*   [`unist-util-visit-parents`](https://github.com/syntax-tree/unist-util-visit-parents)
+    — Like `visit`, but with a stack of parents
+*   [`unist-util-filter`](https://github.com/eush77/unist-util-filter)
+    — Create a new tree with all nodes that pass a test

+util-deprecate
+==============
+### The Node.js `util.deprecate()` function with browser support
+
+In Node.js, this module simply re-exports the `util.deprecate()` function.
+
+In the web browser (i.e. via browserify), a browser-specific implementation
+of the `util.deprecate()` function is used.
+
+
+## API
+
+A `deprecate()` function is the only thing exposed by this module.
+
+``` javascript
+// setup:
+exports.foo = deprecate(foo, 'foo() is deprecated, use bar() instead');
+
+
+// users see:
+foo();
+// foo() is deprecated, use bar() instead
+foo();
+foo();
+```

+# vfile-location [![Build Status][travis-badge]][travis] [![Coverage Status][codecov-badge]][codecov]
+
+Convert between positions (line and column-based) and offsets
+(range-based) locations in a [virtual file][vfile].
+
+## Installation
+
+[npm][]:
+
+```bash
+npm install vfile-location
+```
+
+## Usage
+
+```js
+var vfile = require('vfile');
+var vfileLocation = require('vfile-location');
+var location = vfileLocation(vfile('foo\nbar\nbaz'));
+
+location.toOffset({line: 3, column: 3}); //=> 10
+location.toPosition(offset); //=> {line: 3, column: 3, offset: 10}
+```
+
+## API
+
+### `location = vfileLocation(doc)`
+
+Get transform functions for the given `doc` (`string`) or
+[`file`][vfile].
+
+Returns an object with [`toOffset`][to-offset] and
+[`toPosition`][to-position].
+
+### `location.toOffset(position)`
+
+Get the `offset` (`number`) for a line and column-based
+[`position`][position] in the bound file.  Returns `-1`
+when given invalid or out of bounds input.
+
+### `location.toPosition(offset)`
+
+Get the line and column-based [`position`][position] for `offset` in
+the bound file.

+# vfile-message [![Build Status][travis-badge]][travis] [![Coverage Status][codecov-badge]][codecov]
+
+Create [vfile][] messages.
+
+## Installation
+
+[npm][]:
+
+```bash
+npm install vfile-message
+```
+
+## Usage
+
+```js
+var VMessage = require('vfile-message');
+
+var message = new VMessage('`braavo` is misspelt; did you mean `bravo`?', {line: 1, column: 8}, 'spell:typo');
+
+console.log(message);
+```
+
+Yields:
+
+```js
+{ [1:8: `braavo` is misspelt; did you mean `bravo`?]
+  reason: '`braavo` is misspelt; did you mean `bravo`?',
+  fatal: null,
+  line: 1,
+  column: 8,
+  location:
+   { start: { line: 1, column: 8 },
+     end: { line: null, column: null } },
+  source: 'spell',
+  ruleId: 'typo' }
+```
+
+## API
+
+### `VMessage(reason[, position][, origin])`
+
+Constructor of a message for `reason` at `position` from `origin`.  When
+an error is passed in as `reason`, copies the stack.
+
+##### Parameters
+
+###### `reason`
+
+Reason for message (`string` or `Error`).  Uses the stack and message of the
+error if given.
+
+###### `position`
+
+Place at which the message occurred in a file ([`Node`][node],
+[`Position`][position], or [`Point`][point], optional).
+
+###### `origin`
+
+Place in code the message originates from (`string`, optional).
+
+Can either be the [`ruleId`][ruleid] (`'rule'`), or a string with both a
+[`source`][source] and a [`ruleId`][ruleid] delimited with a colon
+(`'source:rule'`).
+
+##### Extends
+
+[`Error`][error].
+
+##### Returns
+
+An instance of itself.
+
+##### Properties
+
+###### `reason`
+
+Reason for message (`string`).
+
+###### `fatal`
+
+If `true`, marks associated file as no longer processable (`boolean?`).  If
+`false`, necessitates a (potential) change.  The value can also be `null` or
+`undefined`.
+
+###### `line`
+
+Starting line of error (`number?`).
+
+###### `column`
+
+Starting column of error (`number?`).
+
+###### `location`
+
+Full range information, when available ([`Position`][position]).  Has `start`
+and `end` properties, both set to an object with `line` and `column`, set to
+`number?`.
+
+###### `source`
+
+Namespace of warning (`string?`).
+
+###### `ruleId`
+
+Category of message (`string?`).
+
+###### `stack`
+
+Stack of message (`string?`).
+
+##### Custom properties
+
+It’s OK to store custom data directly on the `VFileMessage`, some of those are
+handled by [utilities][util].
+
+###### `file`
+
+You may add a `file` property with a path of a file (used throughout the
+[**VFile**][vfile] ecosystem).
+
+###### `note`
+
+You may add a `note` property with a long form description of the message
+(supported by [`vfile-reporter`][reporter]).
+
+###### `url`
+
+You may add a `url` property with a link to documentation for the message.

+# ![vfile][]
+
+[![Build Status][build-badge]][build-status]
+[![Coverage Status][coverage-badge]][coverage-status]
+
+**VFile** is a virtual file format used by [**unified**][unified],
+a text processing umbrella (it powers [**retext**][retext] for
+natural language, [**remark**][remark] for markdown, and
+[**rehype**][rehype] for HTML).  Each processors that parse, transform,
+and compile text, and need a virtual representation of files and a
+place to store [messages][] about them.  Plus, they work in the browser.
+**VFile** provides these requirements at a small size, in IE 9 and up.
+
+> **VFile** is different from the excellent [**vinyl**][vinyl]
+> in that it has a smaller API, a smaller size, and focuses on
+> [messages][].
+
+VFile can be used anywhere where files need a lightweight representation.
+For example, it’s used in:
+
+*   [`documentation`](https://github.com/documentationjs/documentation)
+    — The documentation system for modern JavaScript
+*   [`weh`](https://github.com/wehjs/weh)
+    — Declarative small site generator
+*   [`geojsonhint`](https://github.com/mapbox/geojsonhint)
+    — Complete, fast, standards-based validation for geojson
+
+## Installation
+
+[npm][]:
+
+```bash
+npm install vfile
+```

+
+```js

+
+var file = vfile({path: '~/example.txt', contents: 'Alpha *braavo* charlie.'});
+
+file.path; //=> '~/example.txt'
+file.dirname; //=> '~'
+
+file.extname = '.md';
+
+file.basename; //=> 'example.md'
+
+file.basename = 'index.text';
+
+file.history; //=> ['~/example.txt', '~/example.md', '~/index.text']
+
+file.message('`braavo` is misspelt; did you mean `bravo`?', {line: 1, column: 8});
+
+console.log(file.messages);
+```
+
+Yields:
+
+```js
+[ { [~/index.text:1:8: `braavo` is misspelt; did you mean `bravo`?]
+    message: '`braavo` is misspelt; did you mean `bravo`?',
+    name: '~/index.text:1:8',
+    file: '~/index.text',
+    reason: '`braavo` is misspelt; did you mean `bravo`?',
+    line: 1,
+    column: 8,
+    location: { start: [Object], end: [Object] },
+    ruleId: null,
+    source: null,
+    fatal: false } ]
+```
+
+## Utilities
+
+The following list of projects includes tools for working with virtual
+files.  See [**Unist**][unist] for projects working with nodes.
+
+*   [`convert-vinyl-to-vfile`](https://github.com/dustinspecker/convert-vinyl-to-vfile)
+    — Convert from [Vinyl][]
+*   [`is-vfile-message`](https://github.com/shinnn/is-vfile-message)
+    — Check if a value is a `VMessage` object

+## Reporters
+
+The following list of projects show linting results for given virtual files.
+Reporters _must_ accept `Array.<VFile>` as their first argument, and return
+`string`.  Reporters _may_ accept other values too, in which case it’s suggested
+to stick to `vfile-reporter`s interface.

+
+## API
+
+### `VFile([options])`
+
+Create a new virtual file.  If `options` is `string` or `Buffer`, treats
+it as `{contents: options}`.  If `options` is a `VFile`, returns it.
+All other options are set on the newly created `vfile`.
+
+Path related properties are set in the following order (least specific
+to most specific): `history`, `path`, `basename`, `stem`, `extname`,
+`dirname`.
+
+It’s not possible to set either `dirname` or `extname` without setting
+either `history`, `path`, `basename`, or `stem` as well.
+
+###### Example
+
+```js
+vfile();
+vfile('console.log("alpha");');
+vfile(Buffer.from('exit 1'));
+vfile({path: path.join(__dirname, 'readme.md')});
+vfile({stem: 'readme', extname: '.md', dirname: __dirname});
+vfile({other: 'properties', are: 'copied', ov: {e: 'r'}});
+```
+
+### `vfile.contents`
+
+`Buffer`, `string`, `null` — Raw value.
+
+### `vfile.cwd`
+
+`string` — Base of `path`.  Defaults to `process.cwd()`.
+
+### `vfile.path`
+
+`string?` — Path of `vfile`.  Cannot be nullified.
+
+### `vfile.basename`
+
+`string?` — Current name (including extension) of `vfile`.  Cannot
+contain path separators.  Cannot be nullified either (use
+`file.path = file.dirname` instead).
+
+### `vfile.stem`
+
+`string?` — Name (without extension) of `vfile`.  Cannot be nullified,
+and cannot contain path separators.
+
+### `vfile.extname`
+
+`string?` — Extension (with dot) of `vfile`.  Cannot be set if
+there’s no `path` yet and cannot contain path separators.
+
+### `vfile.dirname`
+
+`string?` — Path to parent directory of `vfile`.  Cannot be set if
+there’s no `path` yet.
+
+### `vfile.history`
+
+`Array.<string>` — List of file-paths the file moved between.
+
+### `vfile.messages`
+
+[`Array.<VMessage>`][message] — List of messages associated with the file.
+
+### `vfile.data`
+
+`Object` — Place to store custom information.  It’s OK to store custom
+data directly on the `vfile`, moving it to `data` gives a _little_ more
+privacy.
+
+### `VFile#toString([encoding])`
+
+Convert contents of `vfile` to string.  If `contents` is a buffer,
+`encoding` is used to stringify buffers (default: `'utf8'`).
+
+### `VFile#message(reason[, position][, origin])`
+
+Associates a message with the file, where `fatal` is set to `false`.
+Constructs a new [`VMessage`][vmessage] and adds it to
+[`vfile.messages`][messages].
+
+##### Returns
+
+[`VMessage`][vmessage].
+
+### `VFile#info(reason[, position][, origin])`
+
+Associates an informational message with the file, where `fatal` is set to
+`null`.  Calls [`#message()`][message] internally.
+
+##### Returns
+
+[`VMessage`][vmessage].
+
+### `VFile#fail(reason[, position][, origin])`
+
+Associates a fatal message with the file, then immediately throws it.
+Note: fatal errors mean a file is no longer processable.
+Calls [`#message()`][message] internally.
+
+##### Throws
+
+[`VMessage`][vmessage].

+# which
+
+Like the unix `which` utility.
+
+Finds the first instance of a specified executable in the PATH
+environment variable.  Does not cache the results, so `hash -r` is not
+needed when the PATH changes.
+
+## USAGE
+
+```javascript
+var which = require('which')
+
+// async usage
+which('node', function (er, resolvedPath) {
+  // er is returned if no "node" is found on the PATH
+  // if it is found, then the absolute path to the exec is returned
+})
+
+// sync usage
+// throws if not found
+var resolved = which.sync('node')
+
+// if nothrow option is used, returns null if not found
+resolved = which.sync('node', {nothrow: true})
+
+// Pass options to override the PATH and PATHEXT environment vars.
+which('node', { path: someOtherPath }, function (er, resolved) {
+  if (er)
+    throw er
+  console.log('found at %j', resolved)
+})
+```
+
+## CLI USAGE
+
+Same as the BSD `which(1)` binary.
+
+```
+usage: which [-as] program ...
+```
+
+## OPTIONS
+
+You may pass an options object as the second argument.
+
+- `path`: Use instead of the `PATH` environment variable.
+- `pathExt`: Use instead of the `PATHEXT` environment variable.
+- `all`: Return all matches, instead of just the first one.  Note that
+  this means the function returns an array of strings instead of a
+  single string.

+
+methods
+=======
+
+var wrap = require('wordwrap');
+
+wrap(stop), wrap(start, stop, params={mode:"soft"})
+---------------------------------------------------
+
+Returns a function that takes a string and returns a new string.
+
+Pad out lines with spaces out to column `start` and then wrap until column
+`stop`. If a word is longer than `stop - start` characters it will overflow.
+
+In "soft" mode, split chunks by `/(\S+\s+/` and don't break up chunks which are
+longer than `stop - start`, in "hard" mode, split chunks with `/\b/` and break
+up chunks longer than `stop - start`.
+
+wrap.hard(start, stop)
+----------------------
+
+Like `wrap()` but with `params.mode = "hard"`.

+
+Extend like a boss
+
+xtend is a basic utility library which allows you to extend an object by appending all of the properties from each object in a list. When there are identical properties, the right-most property takes precedence.
+
+## Examples
+
+```js
+var extend = require("xtend")
+
+// extend returns a new object. Does not mutate arguments
+var combination = extend({
+    a: "a",
+    b: 'c'
+}, {
+    b: "b"
+})
+// { a: "a", b: "b" }
+```

+# yallist
+
+Yet Another Linked List
+
+There are many doubly-linked list implementations like it, but this
+one is mine.
+
+For when an array would be too big, and a Map can't be iterated in
+reverse order.
+
+
+[![Build Status](https://travis-ci.org/isaacs/yallist.svg?branch=master)](https://travis-ci.org/isaacs/yallist) [![Coverage Status](https://coveralls.io/repos/isaacs/yallist/badge.svg?service=github)](https://coveralls.io/github/isaacs/yallist)
+
+## basic usage
+
+```javascript
+var yallist = require('yallist')
+var myList = yallist.create([1, 2, 3])
+myList.push('foo')
+myList.unshift('bar')
+// of course pop() and shift() are there, too
+console.log(myList.toArray()) // ['bar', 1, 2, 3, 'foo']
+myList.forEach(function (k) {
+  // walk the list head to tail
+})
+myList.forEachReverse(function (k, index, list) {
+  // walk the list tail to head
+})
+var myDoubledList = myList.map(function (k) {
+  return k + k
+})
+// now myDoubledList contains ['barbar', 2, 4, 6, 'foofoo']
+// mapReverse is also a thing
+var myDoubledListReverse = myList.mapReverse(function (k) {
+  return k + k
+}) // ['foofoo', 6, 4, 2, 'barbar']
+
+var reduced = myList.reduce(function (set, entry) {
+  set += entry
+  return set
+}, 'start')
+console.log(reduced) // 'startfoo123bar'
+```
+
+## api
+
+The whole API is considered "public".
+
+Functions with the same name as an Array method work more or less the
+same way.
+
+There's reverse versions of most things because that's the point.
+
+### Yallist
+
+Default export, the class that holds and manages a list.
+
+Call it with either a forEach-able (like an array) or a set of
+arguments, to initialize the list.
+
+The Array-ish methods all act like you'd expect.  No magic length,
+though, so if you change that it won't automatically prune or add
+empty spots.
+
+### Yallist.create(..)
+
+Alias for Yallist function.  Some people like factories.
+
+#### yallist.head
+
+The first node in the list
+
+#### yallist.tail
+
+The last node in the list
+
+#### yallist.length
+
+The number of nodes in the list.  (Change this at your peril.  It is
+not magic like Array length.)
+
+#### yallist.toArray()
+
+Convert the list to an array.
+
+#### yallist.forEach(fn, [thisp])
+
+Call a function on each item in the list.
+
+#### yallist.forEachReverse(fn, [thisp])
+
+Call a function on each item in the list, in reverse order.
+
+#### yallist.get(n)
+
+Get the data at position `n` in the list.  If you use this a lot,
+probably better off just using an Array.
+
+#### yallist.getReverse(n)
+
+Get the data at position `n`, counting from the tail.
+
+#### yallist.map(fn, thisp)
+
+Create a new Yallist with the result of calling the function on each
+item.
+
+#### yallist.mapReverse(fn, thisp)
+
+Same as `map`, but in reverse.
+
+#### yallist.pop()
+
+Get the data from the list tail, and remove the tail from the list.
+
+#### yallist.push(item, ...)
+
+Insert one or more items to the tail of the list.
+
+#### yallist.reduce(fn, initialValue)
+
+Like Array.reduce.
+
+#### yallist.reduceReverse
+
+Like Array.reduce, but in reverse.
+
+#### yallist.reverse
+
+Reverse the list in place.
+
+#### yallist.shift()
+
+Get the data from the list head, and remove the head from the list.
+
+#### yallist.slice([from], [to])
+
+Just like Array.slice, but returns a new Yallist.
+
+#### yallist.sliceReverse([from], [to])
+
+Just like yallist.slice, but the result is returned in reverse.
+
+#### yallist.toArray()
+
+Create an array representation of the list.
+
+#### yallist.toArrayReverse()
+
+Create a reversed array representation of the list.
+
+#### yallist.unshift(item, ...)
+
+Insert one or more items to the head of the list.
+
+#### yallist.unshiftNode(node)
+
+Move a Node object to the front of the list.  (That is, pull it out of
+wherever it lives, and make it the new head.)
+
+If the node belongs to a different list, then that list will remove it
+first.
+
+#### yallist.pushNode(node)
+
+Move a Node object to the end of the list.  (That is, pull it out of
+wherever it lives, and make it the new tail.)
+
+If the node belongs to a list already, then that list will remove it
+first.
+
+#### yallist.removeNode(node)
+
+Remove a node from the list, preserving referential integrity of head
+and tail and other nodes.
+
+Will throw an error if you try to have a list remove a node that
+doesn't belong to it.
+
+### Yallist.Node
+
+The class that holds the data and is actually the list.
+
+Call with `var n = new Node(value, previousNode, nextNode)`
+
+Note that if you do direct operations on Nodes themselves, it's very
+easy to get into weird states where the list is broken.  Be careful :)
+
+#### node.next
+
+The next node in the list.
+
+#### node.prev
+
+The previous node in the list.
+
+#### node.value
+
+The data the node contains.
+
+#### node.list
+
+The list to which this node belongs.  (Null if it does not belong to
+any list.)
