The return value will +be an abstract syntax tree object as specified by the +[Mozilla Parser API][mozapi]. + +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. + +[mozapi]: https://developer.mozilla.org/en-US/docs/SpiderMonkey/Parser_API + +- **ecmaVersion**: Indicates the ECMAScript version to parse. Must be + either 3, 5, or 6. This influences support for strict mode, the set + of reserved words, and support for new syntax features. Default is 5. + +- **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`. 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 `tokenize()` returns. + + 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", + "range": ..., + "loc": ... + } + ``` + + 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 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.tokenize(str)) { + // iterate over the tokens +} + +// transform code to array of tokens: +var tokens = [...acorn.tokenize(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' +``` + +[escodegen]: https://github.com/Constellation/escodegen + +#### Using Acorn in an environment with a Content Security Policy + +Some contexts, such as Chrome Web Apps, disallow run-time code evaluation. +Acorn uses `new Function` to generate fast functions that test whether +a word is in a given set, and will trigger a security error when used +in a context with such a +[Content Security Policy](http://www.html5rocks.com/en/tutorials/security/content-security-policy/#eval-too) +(see [#90](https://github.com/marijnh/acorn/issues/90) and +[#123](https://github.com/marijnh/acorn/issues/123)). + +The `dist/acorn_csp.js` file in the distribution (which is built +by the `bin/without_eval` script) has the generated code inlined, and +can thus run without evaluating anything. + +### dist/acorn_loose.js ### + +This file implements an error-tolerant parser. It exposes a single +function. + +**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 +[Mozilla Parser API][mozapi]. 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 it 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 callbacks in the `state` 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` end `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`: Sets the ECMAScript version to parse. Default is + version 5. + +- `--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("babelify/node_modules/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 +`plugin` 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.

To use a Streams3 version use `npm install through2@1` to fetch the latest version 1.x.x. More information about Streams2 vs Streams3 and recommendations see the article **[Why I don't use Node's core 'stream' module](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html)**. + +```js +fs.createReadStream('ex.txt') + .pipe(through2(function (chunk, enc, callback) { + for (var i = 0; i < chunk.length; i++) + if (chunk[i] == 97) + chunk[i] = 122 // swap 'a' for 'z' + + this.push(chunk) + + callback() + })) + .pipe(fs.createWriteStream('out.txt')) +``` + +Or object streams: + +```js +var all = [] + +fs.createReadStream('data.csv') + .pipe(csv2()) + .pipe(through2.obj(function (chunk, enc, callback) { + var data = { + name : chunk[0] + , address : chunk[3] + , phone : chunk[10] + } + this.push(data) + + callback() + })) + .on('data', function (data) { + all.push(data) + }) + .on('end', function () { + doSomethingSpecial(all) + }) +``` + +Note that `through2.obj(fn)` is a convenience wrapper around `through2({ objectMode: true }, fn)`. + +## API + +<b><code>through2([ options, ] [ transformFunction ] [, flushFunction ])</code></b> + +Consult the **[stream.Transform](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_transform)** documentation for the exact rules of the `transformFunction` (i.e. `this._transform`) and the optional `flushFunction` (i.e. `this._flush`). + +### options + +The options argument is optional and is passed straight through to `stream.Transform`. So you can use `objectMode:true` if you are processing non-binary streams (or just use `through2.obj()`). + +The `options` argument is first, unlike standard convention, because if I'm passing in an anonymous function then I'd prefer for the options argument to not get lost at the end of the call: + +```js +fs.createReadStream('/tmp/important.dat') + .pipe(through2({ objectMode: true, allowHalfOpen: false }, + function (chunk, enc, cb) { + cb(null, 'wut?') // note we can use the second argument on the callback + // to provide data as an alternative to this.push('wut?') + } + ) + .pipe(fs.createWriteStream('/tmp/wut.txt')) +``` + +### transformFunction + +The `transformFunction` must have the following signature: `function (chunk, encoding, callback) {}`. A minimal implementation should call the `callback` function to indicate that the transformation is done, even if that transformation means discarding the chunk. + +To queue a new chunk, call `this.push(chunk)`—this can be called as many times as required before the `callback()` if you have multiple pieces to send on. + +Alternatively, you may use `callback(err, chunk)` as shorthand for emitting a single chunk or an error. + +If you **do not provide a `transformFunction`** then you will get a simple pass-through stream. + +### flushFunction + +The optional `flushFunction` is provided as the last argument (2nd or 3rd, depending on whether you've supplied options) is called just prior to the stream ending. Can be used to finish up any processing that may be in progress. + +```js +fs.createReadStream('/tmp/important.dat') + .pipe(through2( + function (chunk, enc, cb) { cb(null, chunk) }, // transform is a noop + function (cb) { // flush function + this.push('tacking on an extra buffer to the end'); + cb(); + } + )) + .pipe(fs.createWriteStream('/tmp/wut.txt')); +``` + +<b><code>through2.ctor([ options, ] transformFunction[, flushFunction ])</code></b> + +Instead of returning a `stream.Transform` instance, `through2.ctor()` returns a **constructor** for a custom Transform.

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.
