+
+**babel-eslint** allows you to lint **ALL** valid Babel code with the fantastic
+[ESLint](https://github.com/eslint/eslint).
+
+### Why Use babel-eslint
+
+You only need to use babel-eslint if you are using types (Flow) or experimental features not supported in ESLint itself yet. Otherwise try the default parser (you don't have to use it just because you are using Babel).
+
+---
+
+> If there is an issue, first check if it can be reproduced with the regular parser or with the latest versions of `eslint` and `babel-eslint`!
+
+For questions and support please visit the [`#discussion`](https://babeljs.slack.com/messages/discussion/) babel slack channel (sign up [here](https://github.com/babel/notes/issues/38)) or eslint [gitter](https://gitter.im/eslint/eslint)!
+
+> Note that the `ecmaFeatures` config property may still be required for ESLint to work properly with features not in ECMAScript 5 by default. Examples are `globalReturn` and `modules`).
+
+## Known Issues
+
+Flow:
+> Check out [eslint-plugin-flowtype](https://github.com/gajus/eslint-plugin-flowtype): An `eslint` plugin that makes flow type annotations global variables and marks declarations as used. Solves the problem of false positives with `no-undef` and `no-unused-vars`.
+- `no-undef` for global flow types: `ReactElement`, `ReactClass` [#130](https://github.com/babel/babel-eslint/issues/130#issuecomment-111215076)
+  - Workaround: define types as globals in `.eslintrc` or define types and import them `import type ReactElement from './types'`
+- `no-unused-vars/no-undef` with Flow declarations (`declare module A {}`) [#132](https://github.com/babel/babel-eslint/issues/132#issuecomment-112815926)
+
+Modules/strict mode
+- `no-unused-vars: [2, {vars: local}]` [#136](https://github.com/babel/babel-eslint/issues/136)
+
+Please check out [eslint-plugin-react](https://github.com/yannickcr/eslint-plugin-react) for React/JSX issues
+- `no-unused-vars` with jsx
+
+Please check out [eslint-plugin-babel](https://github.com/babel/eslint-plugin-babel) for other issues
+
+## How does it work?
+
+ESLint allows custom parsers. This is great but some of the syntax nodes that Babel supports
+aren't supported by ESLint. When using this plugin, ESLint is monkeypatched and your code is
+transformed into code that ESLint can understand. All location info such as line numbers,
+columns is also retained so you can track down errors with ease.
+
+Basically `babel-eslint` exports an [`index.js`](/index.js) that a linter can use.
+It just needs to export a `parse` method that takes in a string of code and outputs an AST.
+
+## Usage
+
+### Supported ESLint versions
+
+ESLint | babel-eslint
+------------ | -------------
+3.x | >= 6.x
+2.x | >= 6.x
+1.x | >= 5.x
+
+### Install
+
+Ensure that you have substituted the correct version lock for `eslint` and `babel-eslint` into this command:
+
+```sh
+$ npm install eslint@3.x babel-eslint@7 --save-dev
+# or
+$ yarn add eslint@3.x babel-eslint@7 -D
+```
+
+### Setup
+
+**.eslintrc**
+
+```json
+{
+  "parser": "babel-eslint",
+  "rules": {
+    "strict": 0
+  }
+}
+```
+
+Check out the [ESLint docs](http://eslint.org/docs/rules/) for all possible rules.
+
+### Configuration
+
+`sourceType` can be set to `'module'`(default) or `'script'` if your code isn't using ECMAScript modules.
+`allowImportExportEverywhere` can be set to true to allow import and export declarations to appear anywhere a statement is allowed if your build environment supports that. By default, import and export declarations can only appear at a program's top level.
+`codeFrame` can be set to false to disable the code frame in the reporter. This is useful since some eslint formatters don't play well with it.
+
+**.eslintrc**
+
+```json
+{
+  "parser": "babel-eslint",
+  "parserOptions": {
+    "sourceType": "module",
+    "allowImportExportEverywhere": false,
+    "codeFrame": false
+  }
+}
+```
+
+### Run
+
+```sh
+$ eslint your-files-here
+```

+# @babel/code-frame
+
+> Generate errors that contain a code frame that point to source locations.
+
+## Install
+
+```sh
+npm install --save-dev @babel/code-frame
+```
+
+## Usage
+
+```js
+import { codeFrameColumns } from '@babel/code-frame';
+
+const rawLines = `class Foo {
+  constructor()
+}`;
+const location = { start: { line: 2, column: 16 } };
+
+const result = codeFrameColumns(rawLines, location, { /* options */ });
+
+console.log(result);
+```
+
+```
+  1 | class Foo {
+> 2 |   constructor()
+    |                ^
+  3 | }
+```
+
+If the column number is not known, you may omit it.
+
+You can also pass an `end` hash in `location`.
+
+```js
+import { codeFrameColumns } from '@babel/code-frame';
+
+const rawLines = `class Foo {
+  constructor() {
+    console.log("hello");
+  }
+}`;
+const location = { start: { line: 2, column: 17 }, end: { line: 4, column: 3 } };
+
+const result = codeFrameColumns(rawLines, location, { /* options */ });
+
+console.log(result);
+```
+
+```
+  1 | class Foo {
+> 2 |   constructor() {
+    |                 ^
+> 3 |     console.log("hello");
+    | ^^^^^^^^^^^^^^^^^^^^^^^^^
+> 4 |   }
+    | ^^^
+  5 | };
+```
+
+## 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`.
+
+## Upgrading from prior versions
+
+Prior to version 7, the only API exposed by this module was for a single line and optional column pointer. The old API will now log a deprecation warning.
+
+The new API takes a `location` object, similar to what is available in an AST.
+
+This is an example of the deprecated (but still available) API:
+
+```js
+import codeFrame from '@babel/code-frame';
+
+const rawLines = `class Foo {
+  constructor()
+}`;
+const lineNumber = 2;
+const colNumber = 16;
+
+const result = codeFrame(rawLines, lineNumber, colNumber, { /* options */ });
+
+console.log(result);
+```
+
+To get the same highlighting using the new API:
+
+```js
+import { codeFrameColumns } from '@babel/code-frame';
+
+const rawLines = `class Foo {
+  constructor() {
+    console.log("hello");
+  }
+}`;
+const location = { start: { line: 2, column: 16 } };
+
+const result = codeFrameColumns(rawLines, location, { /* options */ });
+
+console.log(result);
+```

+# @babel/template
+
+> Generate an AST from a string template or template literal.
+
+In computer science, this is known as an implementation of quasiquotes.
+
+## Install
+
+```sh
+npm install --save-dev @babel/template
+```
+
+## String Usage
+
+```js
+import template from "@babel/template";
+import generate from "@babel/generator";
+import * as t from "@babel/types";
+
+const buildRequire = template(`
+  var IMPORT_NAME = require(SOURCE);
+`);
+
+const ast = buildRequire({
+  IMPORT_NAME: t.identifier("myModule"),
+  SOURCE: t.stringLiteral("my-module")
+});
+
+console.log(generate(ast).code);
+```
+
+```js
+const myModule = require("my-module");
+```
+
+### `.ast`
+
+If no placeholders are in use and you just want a simple way to parse a
+string into an AST, you can use the `.ast` version of the template.
+
+```js
+const ast = template.ast(`
+  var myModule = require("my-module");
+`);
+```
+which will parse and return the AST directly.
+
+
+## Template Literal Usage
+
+```js
+import template from "@babel/template";
+import generate from "@babel/generator";
+import * as t from "@babel/types";
+
+const fn = template`
+  var IMPORT_NAME = require('${"my-module"}');
+`);
+
+const ast = fn({
+  IMPORT_NAME: t.identifier("myModule");
+});
+
+console.log(generate(ast).code);
+```
+
+Note that placeholders can be passed directly as part of the template literal
+in order to make things as readable as possible, or they can be passed into
+the template function.
+
+### `.ast`
+
+If no placeholders are in use and you just want a simple way to parse a
+string into an AST, you can use the `.ast` version of the template.
+
+```js
+const name = "my-module";
+const mod = "myModule";
+
+const ast = template.ast`
+  var ${mod} = require("${name}");
+`;
+```
+which will parse and return the AST directly. Note that unlike the string-based
+version mentioned earlier, since this is a template literal, it is still
+valid to perform replacements using template literal replacements.
+
+
+## AST results
+
+The `@babel/template` API exposes a few flexible APIs to make it as easy as
+possible to create ASTs with an expected structure. Each of these also has
+the `.ast` property mentioned above.
+
+### `template`
+
+`template` returns either a single statement, or an array of
+statements, depending on the parsed result.
+
+### `template.smart`
+
+This is the same as the default `template` API, returning either a single
+node, or an array of nodes, depending on the parsed result.
+
+### `template.statement`
+
+`template.statement("foo;")()` returns a single statement node, and throw
+an exception if the result is anything but a single statement.
+
+### `template.statements`
+
+`template.statements("foo;foo;")()` returns an array of statement nodes.
+
+### `template.expression`
+
+`template.expression("foo")()` returns the expression node.
+
+### `template.program`
+
+`template.program("foo;")()` returns the `Program` node for the template.
+
+
+## API
+
+### `template(code, [opts])`
+
+#### code
+
+Type: `string`
+
+#### options
+
+`@babel/template` accepts all of the options from [babylon](https://github.com/babel/babel/tree/master/packages/babylon), and specifies
+some defaults of its own:
+
+* `allowReturnOutsideFunction` is set to `true` by default.
+* `allowSuperOutsideMethod` is set to `true` by default.
+* `sourceType` is set to `module` by default.
+
+##### placeholderWhitelist
+
+Type: `Set<string>`
+Default: `undefined`
+
+A set of placeholder names to automatically accept. Items in this list do
+not need to match the given placeholder pattern.
+
+##### placeholderPattern
+
+Type: `RegExp | false`
+Default: `/^[_$A-Z0-9]+$/`
+
+A pattern to search for when looking for Identifier and StringLiteral
+nodes that should be considered placeholders.
+'false' will disable placeholder searching entirely, leaving only the
+'placeholderWhitelist' value to find placeholders.
+
+##### preserveComments
+
+Type: `boolean`
+Default: `false`
+
+Set this to `true` to preserve any comments from the `code` parameter.
+
+#### Return value
+
+By default `@babel/template` returns a `function` which is invoked with an
+optional object of replacements. See the usage section for an example.
+
+When using `.ast`, the AST will be returned directly.

+# @babel/traverse
+
+> @babel/traverse maintains the overall tree state, and is responsible for replacing, removing, and adding nodes.
+
+## Install
+
+```sh
+$ npm install --save @babel/traverse
+```
+
+## Usage
+
+We can use it alongside Babylon to traverse and update nodes:
+
+```js
+import * as babylon from "babylon";
+import traverse from "@babel/traverse";
+
+const code = `function square(n) {
+  return n * n;
+}`;
+
+const ast = babylon.parse(code);
+
+traverse(ast, {
+  enter(path) {
+    if (path.isIdentifier({ name: "n" })) {
+      path.node.name = "x";
+    }
+  }
+});
+```

+# 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
+```

+## Credits
+
+Heavily based on [acorn](https://github.com/marijnh/acorn) and [acorn-jsx](https://github.com/RReverser/acorn-jsx),

+
+## API
+
+### `babylon.parse(code, [options])`
+
+### `babylon.parseExpression(code, [options])`
+
+`parse()` parses the provided `code` as an entire ECMAScript program, while
+`parseExpression()` tries to parse a single Expression with performance in
+mind. When in doubt, use `.parse()`.
+
+### Options
+
+- **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.
+
+- **allowReturnOutsideFunction**: By default, a return statement at
+  the top level raises an error. Set this to `true` to accept such
+  code.
+
+- **allowSuperOutsideMethod**: TODO
+
+- **sourceType**: Indicate the mode the code should be parsed in. Can be
+  one of `"script"`, `"module"`, or `"unambiguous"`. Defaults to `"script"`. `"unambiguous"` will make Babylon attempt to _guess_, based on the presence of ES6 `import` or `export` statements. Files with ES6 `import`s and `export`s are considered `"module"` and are otherwise `"script"`.
+
+- **sourceFilename**: Correlate output AST nodes with their source filename.  Useful when generating code and source maps from the ASTs of multiple input files.
+
+- **startLine**: By default, the first line of code parsed is treated as line 1. You can provide a line number to alternatively start with. Useful for integration with other source tools.
+
+- **plugins**: Array containing the plugins that you want to enable.
+
+- **strictMode**: TODO
+
+- **ranges**: Adds a `ranges` property to each node: `[node.start, node.end]`
+
+- **tokens**: Adds all parsed tokens to a `tokens` property on the `File` node
+
+### Output
+
+Babylon generates AST according to [Babel AST format][].
+It is based on [ESTree spec][] with the following deviations:
+
+> There is now an `estree` plugin which reverts these deviations
+
+- [Literal][] token is replaced with [StringLiteral][], [NumericLiteral][], [BooleanLiteral][], [NullLiteral][], [RegExpLiteral][]
+- [Property][] token is replaced with [ObjectProperty][] and [ObjectMethod][]
+- [MethodDefinition][] is replaced with [ClassMethod][]
+- [Program][] and [BlockStatement][] contain additional `directives` field with [Directive][] and [DirectiveLiteral][]
+- [ClassMethod][], [ObjectProperty][], and [ObjectMethod][] value property's properties in [FunctionExpression][] is coerced/brought into the main method node.
+
+AST for JSX code is based on [Facebook JSX AST][] with the addition of one node type:
+
+- `JSXText`

+
+### Semver
+
+Babylon follows semver in most situations. The only thing to note is that some spec-compliancy bug fixes may be released under patch versions.
+
+For example: We push a fix to early error on something like [#107](https://github.com/babel/babylon/pull/107) - multiple default exports per file. That would be considered a bug fix even though it would cause a build to fail.
+
+### Example
+
+```javascript
+require("babylon").parse("code", {
+  // parse in strict mode and allow module declarations
+  sourceType: "module",
+
+  plugins: [
+    // enable jsx and flow syntax
+    "jsx",
+    "flow"
+  ]
+});
+```

+### FAQ
+
+#### Will Babylon support a plugin system?
+
+Previous issues: [babel/babel#1351](https://github.com/babel/babel/issues/1351), [#500](https://github.com/babel/babylon/issues/500).
+
+We currently aren't willing to commit to supporting the API for plugins or the resulting ecosystem (there is already enough work maintaining Babel's own plugin system). It's not clear how to make that API effective, and it would limit out ability to refactor and optimize the codebase.
+
+Our current recommendation for those that want to create their own custom syntax is for users to fork Babylon.
+
+To consume your custom parser, you can add to your `.babelrc` via its npm package name or require it if using JavaScript,
+
+```json
+{
+  "parserOpts": {
+    "parser": "custom-fork-of-babylon-on-npm-here"
+  }
+}
+```

+
+## 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.

+# 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.

+$ 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:

+
+#### 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.

+# 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
+    }
+});
+```

+
+[![npm version](https://img.shields.io/npm/v/eslint-visitor-keys.svg)](https://www.npmjs.com/package/eslint-visitor-keys)
+[![Downloads/month](https://img.shields.io/npm/dm/eslint-visitor-keys.svg)](http://www.npmtrends.com/eslint-visitor-keys)
+[![Build Status](https://travis-ci.org/eslint/eslint-visitor-keys.svg?branch=master)](https://travis-ci.org/eslint/eslint-visitor-keys)
+[![Dependency Status](https://david-dm.org/eslint/eslint-visitor-keys.svg)](https://david-dm.org/eslint/eslint-visitor-keys)
+
+Constants and utilities about visitor keys to traverse AST.
+
+## 💿 Installation
+
+Use [npm] to install.
+
+```bash
+$ npm install eslint-visitor-keys
+```
+
+### Requirements
+
+- [Node.js] 4.0.0 or later.
+
+## 📖 Usage
+
+```js
+const evk = require("eslint-visitor-keys")
+```
+
+### evk.KEYS
+
+> type: `{ [type: string]: string[] | undefined }`
+
+Visitor keys. This keys are frozen.
+
+This is an object. Keys are the type of [ESTree] nodes. Their values are an array of property names which have child nodes.
+
+For example:
+
+```
+console.log(evk.KEYS.AssignmentExpression) // → ["left", "right"]
+```
+
+### evk.getKeys(node)
+
+> type: `(node: object) => string[]`
+
+Get the visitor keys of a given AST node.
+
+This is similar to `Object.keys(node)` of ES Standard, but some keys are excluded: `parent`, `leadingComments`, `trailingComments`, and names which start with `_`.
+
+This will be used to traverse unknown nodes.
+
+For example:
+
+```
+const node = {
+    type: "AssignmentExpression",
+    left: { type: "Identifier", name: "foo" },
+    right: { type: "Literal", value: 0 }
+}
+console.log(evk.getKeys(node)) // → ["type", "left", "right"]
+```
+
+### evk.unionWith(additionalKeys)
+
+> type: `(additionalKeys: object) => { [type: string]: string[] | undefined }`
+
+Make the union set with `evk.KEYS` and the given keys.
+
+- The order of keys is, `additionalKeys` is at first, then `evk.KEYS` is concatenated after that.
+- It removes duplicated keys as keeping the first one.
+
+For example:
+
+```
+console.log(evk.unionWith({
+    MethodDefinition: ["decorators"]
+})) // → { ..., MethodDefinition: ["decorators", "key", "value"], ... }
+```
+
+## 📰 Change log
+
+See [GitHub releases](https://github.com/eslint/eslint-visitor-keys/releases).
+
+## 🍻 Contributing
+
+Welcome. See [ESLint contribution guidelines](https://eslint.org/docs/developer-guide/contributing/).
+
+### Development commands
+
+- `npm test` runs tests and measures code coverage.
+- `npm run lint` checks source codes with ESLint.
+- `npm run coverage` opens the code coverage report of the previous test with your default browser.
+- `npm run release` publishes this package to [npm] registory.

+### 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.

+# 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.

+# invariant
+
+[![Build Status](https://travis-ci.org/zertosh/invariant.svg?branch=master)](https://travis-ci.org/zertosh/invariant)
+
+A mirror of Facebook's `invariant` (e.g. [React](https://github.com/facebook/react/blob/v0.13.3/src/vendor/core/invariant.js), [flux](https://github.com/facebook/flux/blob/2.0.2/src/invariant.js)).
+
+A way to provide descriptive errors in development but generic errors in production.
+
+## Install
+
+With [npm](http://npmjs.org) do:
+
+```sh
+npm install invariant
+```
+
+## `invariant(condition, message)`
+
+```js
+var invariant = require('invariant');
+
+invariant(someTruthyVal, 'This will not throw');
+// No errors
+
+invariant(someFalseyVal, 'This will throw an error with this message');
+// Error: Invariant Violation: This will throw an error with this message
+```
+
+**Note:** When `process.env.NODE_ENV` is not `production`, the message is required. If omitted, `invariant` will throw regardless of the truthiness of the condition. When `process.env.NODE_ENV` is `production`, the message is optional – so they can be minified away.
+
+### Browser
+
+When used with [browserify](https://github.com/substack/node-browserify), it'll use `browser.js` (instead of `invariant.js`) and the [envify](https://github.com/hughsk/envify) transform will inline the value of `process.env.NODE_ENV`.
+
+### Node
+
+The node version is optimized around the performance implications of accessing `process.env`. The value of `process.env.NODE_ENV` is cached, and repeatedly used instead of reading `proces.env`. See [Server rendering is slower with npm react #812](https://github.com/facebook/react/issues/812)

+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).

+# 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.

+   *
+   * Explicit chain sequences, which must be unwrapped with `_#value`, may be

+   * The execution of chained methods is lazy, that is, it's deferred until

+   * 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`
+   *

+     * Creates a `lodash` object which wraps `value` to enable implicit method

+     * 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

+     * The execution of chained methods is lazy, that is, it's deferred until

+     *
+     * 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.

+ * 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:

+# loose-envify
+
+[![Build Status](https://travis-ci.org/zertosh/loose-envify.svg?branch=master)](https://travis-ci.org/zertosh/loose-envify)
+
+Fast (and loose) selective `process.env` replacer using [js-tokens](https://github.com/lydell/js-tokens) instead of an AST. Works just like [envify](https://github.com/hughsk/envify) but much faster.
+
+## Gotchas
+
+* Doesn't handle broken syntax.
+* Doesn't look inside embedded expressions in template strings.
+  - **this won't work:**
+  ```js
+  console.log(`the current env is ${process.env.NODE_ENV}`);
+  ```
+* Doesn't replace oddly-spaced or oddly-commented expressions.
+  - **this won't work:**
+  ```js
+  console.log(process./*won't*/env./*work*/NODE_ENV);
+  ```
+
+## Usage/Options
+
+loose-envify has the exact same interface as [envify](https://github.com/hughsk/envify), including the CLI.
+
+## Benchmark
+
+```
+envify:
+
+  $ for i in {1..5}; do node bench/bench.js 'envify'; done
+  708ms
+  727ms

+Use this package to easily convert various time formats to milliseconds.
+
+## Examples
+
+```js
+ms('2 days')  // 172800000
+ms('1d')      // 86400000
+ms('10h')     // 36000000

+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!
+
+As always, you can run the tests using: `npm test`

+# 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.

+# 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.

+# to-fast-properties [![Build Status](https://travis-ci.org/sindresorhus/to-fast-properties.svg?branch=master)](https://travis-ci.org/sindresorhus/to-fast-properties)
+
+> Force V8 to use fast properties for an object
+
+[Read more.](http://stackoverflow.com/questions/24987896/)
+
+Use `%HasFastProperties(object)` and `--allow-natives-syntax` to check whether an object already has fast properties.
+
+
+## Install
+
+```
+$ npm install --save to-fast-properties
+```
+
+
+## Usage
+
+```js
+const toFastProperties = require('to-fast-properties');
+
+const obj = {
+	foo: true,
+	bar: true
+};
+
+delete obj.foo;
+// `obj` now has slow properties
+
+toFastProperties(obj);
+// `obj` now has fast properties
+```
