+
+Allow labels in front or `var` declarations, even in strict mode.
+
+### Breaking changes

+
+### Bug fixes
+
+Solve spurious parenthesized pattern errors by temporarily erring on

+correctly yet.
+
+## 4.0.7 (2017-02-02)
+
+### Bug fixes
+
+Accept invalidly rejected code like `(x).y = 2` again.
+
+Don't raise an error when a function _inside_ strict code has a
+non-simple parameter list.
+
+## 4.0.6 (2017-02-02)
+
+### Bug fixes
+
+Fix exponential behavior (manifesting itself as a complete hang for
+even relatively small source files) introduced by the new 'use strict'
+check.
+
+## 4.0.5 (2017-02-02)
+
+### Bug fixes
+
+Disallow parenthesized pattern expressions.
+
+Allow keywords as export names.
+
+Don't allow the `async` keyword to be parenthesized.
+
+Properly raise an error when a keyword contains a character escape.
+
+Allow `"use strict"` to appear after other string literal expressions.

+exported.
+
+## 4.0.3 (2016-08-16)
+
+### Bug fixes
+
+Allow regular function declarations inside single-statement `if`
+branches in loose mode. Forbid them entirely in strict mode.
+
+Properly parse properties named `async` in ES2017 mode.
+
+Fix bug where reserved words were broken in ES2017 mode.
+
+## 4.0.2 (2016-08-11)
+
+### Bug fixes
+
+Don't ignore period or 'e' characters after octal numbers.
+
+Fix broken parsing for call expressions in default parameter values
+of arrow functions.
+
+## 4.0.1 (2016-08-08)
+
+### Bug fixes
+
+Fix false positives in duplicated export name errors.
+
+## 4.0.0 (2016-08-07)
+

+
+A parenthesized class or function expression after `export default` is
+now parsed correctly.
+
+### New features
+
+When `ecmaVersion` is set to 7, Acorn will parse the exponentiation

+
+## Community
+
+Acorn is open source software released under an
+[MIT license](https://github.com/acornjs/acorn/blob/master/LICENSE).
+
+You are welcome to
+[report bugs](https://github.com/acornjs/acorn/issues) or create pull
+requests on [github](https://github.com/acornjs/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, you can download the source and build acorn yourself:
+
+```sh
+git clone https://github.com/acornjs/acorn.git
+cd acorn
+npm install
+npm run build
+```
+
+## 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), 9 (2018) or 10 (2019, 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.
+  
+- **allowAwaitOutsideFunction**: By default, `await` expressions can only appear inside `async` functions. Setting this option to `true` allows to have top-level `await` expressions. They are still not allowed in non-`async` functions, though.
+
+- **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|--ecma10`: 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)
+  }
+})
+```

+// 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.

+# amdefine
+
+A module that can be used to implement AMD's define() in Node. This allows you
+to code to the AMD API and have the module work in node programs without
+requiring those other programs to use AMD.
+
+## Usage
+
+**1)** Update your package.json to indicate amdefine as a dependency:
+
+```javascript
+    "dependencies": {
+        "amdefine": ">=0.1.0"
+    }
+```
+
+Then run `npm install` to get amdefine into your project.
+
+**2)** At the top of each module that uses define(), place this code:
+
+```javascript
+if (typeof define !== 'function') { var define = require('amdefine')(module) }
+```
+
+**Only use these snippets** when loading amdefine. If you preserve the basic structure,
+with the braces, it will be stripped out when using the [RequireJS optimizer](#optimizer).
+
+You can add spaces, line breaks and even require amdefine with a local path, but
+keep the rest of the structure to get the stripping behavior.
+
+As you may know, because `if` statements in JavaScript don't have their own scope, the var
+declaration in the above snippet is made whether the `if` expression is truthy or not. If
+RequireJS is loaded then the declaration is superfluous because `define` is already already
+declared in the same scope in RequireJS. Fortunately JavaScript handles multiple `var`
+declarations of the same variable in the same scope gracefully.
+
+If you want to deliver amdefine.js with your code rather than specifying it as a dependency
+with npm, then just download the latest release and refer to it using a relative path:
+
+[Latest Version](https://github.com/jrburke/amdefine/raw/latest/amdefine.js)
+
+### amdefine/intercept
+
+Consider this very experimental.
+
+Instead of pasting the piece of text for the amdefine setup of a `define`
+variable in each module you create or consume, you can use `amdefine/intercept`
+instead. It will automatically insert the above snippet in each .js file loaded
+by Node.
+
+**Warning**: you should only use this if you are creating an application that
+is consuming AMD style defined()'d modules that are distributed via npm and want
+to run that code in Node.
+
+For library code where you are not sure if it will be used by others in Node or
+in the browser, then explicitly depending on amdefine and placing the code
+snippet above is suggested path, instead of using `amdefine/intercept`. The
+intercept module affects all .js files loaded in the Node app, and it is
+inconsiderate to modify global state like that unless you are also controlling
+the top level app.
+
+#### Why distribute AMD-style modules via npm?
+
+npm has a lot of weaknesses for front-end use (installed layout is not great,
+should have better support for the `baseUrl + moduleID + '.js' style of loading,
+single file JS installs), but some people want a JS package manager and are
+willing to live with those constraints. If that is you, but still want to author
+in AMD style modules to get dynamic require([]), better direct source usage and
+powerful loader plugin support in the browser, then this tool can help.
+
+#### amdefine/intercept usage
+
+Just require it in your top level app module (for example index.js, server.js):
+
+```javascript
+require('amdefine/intercept');
+```
+
+The module does not return a value, so no need to assign the result to a local
+variable.
+
+Then just require() code as you normally would with Node's require(). Any .js
+loaded after the intercept require will have the amdefine check injected in
+the .js source as it is loaded. It does not modify the source on disk, just
+prepends some content to the text of the module as it is loaded by Node.
+
+#### How amdefine/intercept works
+
+It overrides the `Module._extensions['.js']` in Node to automatically prepend
+the amdefine snippet above. So, it will affect any .js file loaded by your
+app.
+
+## define() usage
+
+It is best if you use the anonymous forms of define() in your module:
+
+```javascript
+define(function (require) {
+    var dependency = require('dependency');
+});
+```
+
+or
+
+```javascript
+define(['dependency'], function (dependency) {
+
+});
+```
+
+## RequireJS optimizer integration. <a name="optimizer"></name>
+
+Version 1.0.3 of the [RequireJS optimizer](http://requirejs.org/docs/optimization.html)
+will have support for stripping the `if (typeof define !== 'function')` check
+mentioned above, so you can include this snippet for code that runs in the
+browser, but avoid taking the cost of the if() statement once the code is
+optimized for deployment.
+
+## Node 0.4 Support
+
+If you want to support Node 0.4, then add `require` as the second parameter to amdefine:
+
+```javascript
+//Only if you want Node 0.4. If using 0.5 or later, use the above snippet.
+if (typeof define !== 'function') { var define = require('amdefine')(module, require) }
+```
+
+## Limitations
+
+### Synchronous vs Asynchronous
+
+amdefine creates a define() function that is callable by your code. It will
+execute and trace dependencies and call the factory function *synchronously*,
+to keep the behavior in line with Node's synchronous dependency tracing.
+
+The exception: calling AMD's callback-style require() from inside a factory
+function. The require callback is called on process.nextTick():
+
+```javascript
+define(function (require) {
+    require(['a'], function(a) {
+        //'a' is loaded synchronously, but
+        //this callback is called on process.nextTick().
+    });
+});
+```
+
+### Loader Plugins
+
+Loader plugins are supported as long as they call their load() callbacks
+synchronously. So ones that do network requests will not work. However plugins
+like [text](http://requirejs.org/docs/api.html#text) can load text files locally.
+
+The plugin API's `load.fromText()` is **not supported** in amdefine, so this means
+transpiler plugins like the [CoffeeScript loader plugin](https://github.com/jrburke/require-cs)
+will not work. This may be fixable, but it is a bit complex, and I do not have
+enough node-fu to figure it out yet. See the source for amdefine.js if you want
+to get an idea of the issues involved.
+
+## Tests
+
+To run the tests, cd to **tests** and run:
+
+```
+node all.js
+node all-intercept.js
+```

+
+Convenience wrapper for performing AST transformations with
+[browserify](http://browserify.org/) transform streams. Note that it doesn't
+handle source maps nicely, though pull requests are welcome!
+
+## Usage ##
+
+[![ast-transform](https://nodei.co/npm/ast-transform.png?mini=true)](https://nodei.co/npm/ast-transform)
+
+### `ast(transform[, opts])` ###
+
+Where `transform` is a function that takes a filename and returns a function,
+e.g.:
+
+``` javascript
+var replace = require('replace-method')
+var ast = require('ast-transform')
+var path = require('path')
+
+module.exports = ast(function (file) {
+  if (path.extname(file) !== '.js') return
+
+  return function(ast, done) {
+    // replace require calls with
+    // strings for some reason
+    replace(ast)(['require'], function(node) {
+      return { type: 'Literal', value: 'replaced!' }
+    })
+
+    done()
+  }
+})
+```
+
+Note that you can return a falsey value instead of a function to bail the
+stream early and avoid the parse/deparse overhead. Here's an example of using
+the above with browserify:
+
+``` javascript
+var browserify = require('browserify')
+var example = require('./example')
+var fs = require('fs')
+
+browserify('./index.js')
+  .transform(example)
+  .bundle()
+  .pipe(fs.createWriteStream(__filename + '/bundle.js'))
+```

+### Escodegen [![Build Status](https://secure.travis-ci.org/Constellation/escodegen.png)](http://travis-ci.org/Constellation/escodegen) [![Build Status](https://drone.io/github.com/Constellation/escodegen/status.png)](https://drone.io/github.com/Constellation/escodegen/latest)
+
+Escodegen ([escodegen](http://github.com/Constellation/escodegen)) is
+[ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
+(also popularly known as [JavaScript](http://en.wikipedia.org/wiki/JavaScript>JavaScript))
+code generator from [Parser API](https://developer.mozilla.org/en/SpiderMonkey/Parser_API) AST.
+See [online generator demo](http://constellation.github.com/escodegen/demo/index.html).
+
+
+### Install
+
+Escodegen can be used in a web browser:
+
+    <script src="escodegen.browser.js"></script>
+
+escodegen.browser.js is found in tagged-revision. See Tags on GitHub.
+
+Or in a Node.js application via the package manager:
+
+    npm install escodegen
+
+### Usage
+
+A simple example: the program
+
+    escodegen.generate({
+        type: 'BinaryExpression',
+        operator: '+',
+        left: { type: 'Literal', value: 40 },
+        right: { type: 'Literal', value: 2 }
+    });
+
+produces the string `'40 + 2'`
+
+See the [API page](https://github.com/Constellation/escodegen/wiki/API) for
+options. To run the tests, execute `npm test` in the root directory.
+
+### Building browser bundle / minified browser bundle
+
+At first, executing `npm install` to install the all dev dependencies.
+After that,
+
+    npm run-script build
+
+will generate `escodegen.browser.js`, it is used on the browser environment.
+
+And,
+
+    npm run-script build-min
+
+will generate minified `escodegen.browser.min.js`.

+**Esprima** ([esprima.org](http://esprima.org)) 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](http://en.wikipedia.org/wiki/JavaScript>JavaScript)).
+Esprima is created and maintained by [Ariya Hidayat](http://twitter.com/ariyahidayat),
+with the help of [many contributors](https://github.com/ariya/esprima/contributors).
+
+Esprima runs on web browsers (IE 6+, Firefox 1+, Safari 3+, Chrome 1+, Konqueror 4.6+, Opera 8+) as well as
+[Node.js](http://nodejs.org).
+
+### Features
+
+- Full support for [ECMAScript 5.1](http://www.ecma-international.org/publications/standards/Ecma-262.htm)(ECMA-262)
+- Sensible [syntax tree format](http://esprima.org/doc/index.html#ast) compatible with Mozilla
+[Parser AST](https://developer.mozilla.org/en/SpiderMonkey/Parser_API)
+- Heavily tested (> 550 [unit tests](http://esprima.org/test/) with solid 100% statement coverage)
+- Optional tracking of syntax node location (index-based and line-column)
+- Experimental support for ES6/Harmony (module, class, destructuring, ...)
+
+Esprima is blazing fast (see the [benchmark suite](http://esprima.org/test/benchmarks.html)).
+It is up to 3x faster than UglifyJS v1 and it is still [competitive](http://esprima.org/test/compare.html)
+with the new generation of fast parsers.
+

+### Estraverse [![Build Status](https://secure.travis-ci.org/Constellation/estraverse.png)](http://travis-ci.org/Constellation/estraverse)
+
+Estraverse ([estraverse](http://github.com/Constellation/estraverse)) is
+[ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
+traversal functions from [esmangle project](http://github.com/Constellation/esmangle).
+
+### Example Usage
+
+The following code will output all variables declared at the root of a file.
+
+```javascript
+estraverse.traverse(ast, {
+    enter: function (node, parent) {
+        if (node.type == 'FunctionExpression' || node.type == 'FunctionDeclaration')
+            return estraverse.VisitorOption.Skip;
+    },
+    leave: function (node, parent) {
+        if (node.type == 'VariableDeclarator')
+          console.log(node.id.name);
+    }
+});
+```
+
+We can use `this.skip` and `this.break` functions instead of using Skip and Break.
+
+```javascript
+estraverse.traverse(ast, {
+    enter: function (node) {
+        this.break();
+    }
+});
+```
+
+And estraverse provides `estraverse.replace` function. When returning node from `enter`/`leave`, current node is replaced with it.
+
+```javascript
+result = estraverse.replace(tree, {
+    enter: function (node) {
+        // Replace it with replaced.
+        if (node.type === 'Literal')
+            return replaced;
+    }
+});
+```

+# Change Log
+
+## 0.1.43
+
+* Performance improvements for `SourceMapGenerator` and `SourceNode`. See issue
+  #148 for some discussion and issues #150, #151, and #152 for implementations.
+
+## 0.1.42
+
+* Fix an issue where `SourceNode`s from different versions of the source-map
+  library couldn't be used in conjunction with each other. See issue #142.
+
+## 0.1.41
+
+* Fix a bug with getting the source content of relative sources with a "./"
+  prefix. See issue #145 and [Bug 1090768](bugzil.la/1090768).
+
+* Add the `SourceMapConsumer.prototype.computeColumnSpans` method to compute the
+  column span of each mapping.
+
+* Add the `SourceMapConsumer.prototype.allGeneratedPositionsFor` method to find
+  all generated positions associated with a given original source and line.
+
+## 0.1.40
+
+* Performance improvements for parsing source maps in SourceMapConsumer.
+
+## 0.1.39
+
+* Fix a bug where setting a source's contents to null before any source content
+  had been set before threw a TypeError. See issue #131.
+
+## 0.1.38
+
+* Fix a bug where finding relative paths from an empty path were creating
+  absolute paths. See issue #129.
+
+## 0.1.37
+
+* Fix a bug where if the source root was an empty string, relative source paths
+  would turn into absolute source paths. Issue #124.
+
+## 0.1.36
+
+* Allow the `names` mapping property to be an empty string. Issue #121.
+
+## 0.1.35
+
+* A third optional parameter was added to `SourceNode.fromStringWithSourceMap`
+  to specify a path that relative sources in the second parameter should be
+  relative to. Issue #105.
+
+* If no file property is given to a `SourceMapGenerator`, then the resulting
+  source map will no longer have a `null` file property. The property will
+  simply not exist. Issue #104.
+
+* Fixed a bug where consecutive newlines were ignored in `SourceNode`s.
+  Issue #116.
+
+## 0.1.34
+
+* Make `SourceNode` work with windows style ("\r\n") newlines. Issue #103.
+
+* Fix bug involving source contents and the
+  `SourceMapGenerator.prototype.applySourceMap`. Issue #100.
+
+## 0.1.33
+
+* Fix some edge cases surrounding path joining and URL resolution.
+
+* Add a third parameter for relative path to
+  `SourceMapGenerator.prototype.applySourceMap`.
+
+* Fix issues with mappings and EOLs.
+
+## 0.1.32
+
+* Fixed a bug where SourceMapConsumer couldn't handle negative relative columns
+  (issue 92).
+
+* Fixed test runner to actually report number of failed tests as its process
+  exit code.
+
+* Fixed a typo when reporting bad mappings (issue 87).
+
+## 0.1.31
+
+* Delay parsing the mappings in SourceMapConsumer until queried for a source
+  location.
+
+* Support Sass source maps (which at the time of writing deviate from the spec
+  in small ways) in SourceMapConsumer.
+
+## 0.1.30
+
+* Do not join source root with a source, when the source is a data URI.
+
+* Extend the test runner to allow running single specific test files at a time.
+
+* Performance improvements in `SourceNode.prototype.walk` and
+  `SourceMapConsumer.prototype.eachMapping`.
+
+* Source map browser builds will now work inside Workers.
+
+* Better error messages when attempting to add an invalid mapping to a
+  `SourceMapGenerator`.
+
+## 0.1.29
+
+* Allow duplicate entries in the `names` and `sources` arrays of source maps
+  (usually from TypeScript) we are parsing. Fixes github issue 72.
+
+## 0.1.28
+
+* Skip duplicate mappings when creating source maps from SourceNode; github
+  issue 75.
+
+## 0.1.27
+
+* Don't throw an error when the `file` property is missing in SourceMapConsumer,
+  we don't use it anyway.
+
+## 0.1.26
+
+* Fix SourceNode.fromStringWithSourceMap for empty maps. Fixes github issue 70.
+
+## 0.1.25
+
+* Make compatible with browserify
+
+## 0.1.24
+
+* Fix issue with absolute paths and `file://` URIs. See
+  https://bugzilla.mozilla.org/show_bug.cgi?id=885597
+
+## 0.1.23
+
+* Fix issue with absolute paths and sourcesContent, github issue 64.
+
+## 0.1.22
+
+* Ignore duplicate mappings in SourceMapGenerator. Fixes github issue 21.
+
+## 0.1.21
+
+* Fixed handling of sources that start with a slash so that they are relative to
+  the source root's host.
+
+## 0.1.20
+
+* Fixed github issue #43: absolute URLs aren't joined with the source root
+  anymore.
+
+## 0.1.19
+
+* Using Travis CI to run tests.
+
+## 0.1.18
+
+* Fixed a bug in the handling of sourceRoot.
+
+## 0.1.17
+
+* Added SourceNode.fromStringWithSourceMap.
+
+## 0.1.16
+
+* Added missing documentation.

+# Source Map
+
+This is a library to generate and consume the source map format
+[described here][format].
+
+This library is written in the Asynchronous Module Definition format, and works
+in the following environments:
+
+* Modern Browsers supporting ECMAScript 5 (either after the build, or with an
+  AMD loader such as RequireJS)
+
+* Inside Firefox (as a JSM file, after the build)
+
+* With NodeJS versions 0.8.X and higher
+
+## Node
+
+    $ npm install source-map
+
+## Building from Source (for everywhere else)
+
+Install Node and then run
+
+    $ git clone https://fitzgen@github.com/mozilla/source-map.git
+    $ cd source-map
+    $ npm link .
+
+Next, run
+
+    $ node Makefile.dryice.js
+
+This should spew a bunch of stuff to stdout, and create the following files:
+
+* `dist/source-map.js` - The unminified browser version.
+
+* `dist/source-map.min.js` - The minified browser version.
+
+* `dist/SourceMap.jsm` - The JavaScript Module for inclusion in Firefox source.
+
+## Examples
+
+### Consuming a source map
+
+    var rawSourceMap = {
+      version: 3,
+      file: 'min.js',
+      names: ['bar', 'baz', 'n'],
+      sources: ['one.js', 'two.js'],
+      sourceRoot: 'http://example.com/www/js/',
+      mappings: 'CAAC,IAAI,IAAM,SAAUA,GAClB,OAAOC,IAAID;CCDb,IAAI,IAAM,SAAUE,GAClB,OAAOA'
+    };
+
+    var smc = new SourceMapConsumer(rawSourceMap);
+
+    console.log(smc.sources);
+    // [ 'http://example.com/www/js/one.js',
+    //   'http://example.com/www/js/two.js' ]
+
+    console.log(smc.originalPositionFor({
+      line: 2,
+      column: 28
+    }));
+    // { source: 'http://example.com/www/js/two.js',
+    //   line: 2,
+    //   column: 10,
+    //   name: 'n' }
+
+    console.log(smc.generatedPositionFor({
+      source: 'http://example.com/www/js/two.js',
+      line: 2,
+      column: 10
+    }));
+    // { line: 2, column: 28 }
+
+    smc.eachMapping(function (m) {
+      // ...
+    });

+### Generating a source map
+
+In depth guide:
+[**Compiling to JavaScript, and Debugging with Source Maps**](https://hacks.mozilla.org/2013/05/compiling-to-javascript-and-debugging-with-source-maps/)
+
+#### With SourceNode (high level API)
+
+    function compile(ast) {
+      switch (ast.type) {
+      case 'BinaryExpression':
+        return new SourceNode(
+          ast.location.line,
+          ast.location.column,
+          ast.location.source,
+          [compile(ast.left), " + ", compile(ast.right)]
+        );
+      case 'Literal':
+        return new SourceNode(
+          ast.location.line,
+          ast.location.column,
+          ast.location.source,
+          String(ast.value)
+        );
+      // ...
+      default:
+        throw new Error("Bad AST");
+      }
+    }
+
+    var ast = parse("40 + 2", "add.js");
+    console.log(compile(ast).toStringWithSourceMap({
+      file: 'add.js'
+    }));
+    // { code: '40 + 2',
+    //   map: [object SourceMapGenerator] }
+
+#### With SourceMapGenerator (low level API)
+
+    var map = new SourceMapGenerator({
+      file: "source-mapped.js"
+    });
+
+    map.addMapping({
+      generated: {
+        line: 10,
+        column: 35
+      },
+      source: "foo.js",
+      original: {
+        line: 33,
+        column: 2
+      },
+      name: "christopher"
+    });
+
+    console.log(map.toString());
+    // '{"version":3,"file":"source-mapped.js","sources":["foo.js"],"names":["christopher"],"mappings":";;;;;;;;;mCAgCEA"}'
+
+## API
+
+Get a reference to the module:
+
+    // NodeJS
+    var sourceMap = require('source-map');
+
+    // Browser builds
+    var sourceMap = window.sourceMap;
+
+    // Inside Firefox
+    let sourceMap = {};
+    Components.utils.import('resource:///modules/devtools/SourceMap.jsm', sourceMap);
+
+### SourceMapConsumer
+
+A SourceMapConsumer instance represents a parsed source map which we can query
+for information about the original file positions by giving it a file position
+in the generated source.
+
+#### new SourceMapConsumer(rawSourceMap)
+
+The only parameter is the raw source map (either as a string which can be
+`JSON.parse`'d, or an object). According to the spec, source maps have the
+following attributes:
+
+* `version`: Which version of the source map spec this map is following.
+
+* `sources`: An array of URLs to the original source files.
+
+* `names`: An array of identifiers which can be referrenced by individual
+  mappings.
+
+* `sourceRoot`: Optional. The URL root from which all sources are relative.
+
+* `sourcesContent`: Optional. An array of contents of the original source files.
+
+* `mappings`: A string of base64 VLQs which contain the actual mappings.
+
+* `file`: Optional. The generated filename this source map is associated with.
+
+#### SourceMapConsumer.prototype.computeColumnSpans()
+
+Compute the last column for each generated mapping. The last column is
+inclusive.
+
+#### SourceMapConsumer.prototype.originalPositionFor(generatedPosition)
+
+Returns the original source, line, and column information for the generated
+source's line and column positions provided. The only argument is an object with
+the following properties:
+
+* `line`: The line number in the generated source.
+
+* `column`: The column number in the generated source.
+
+and an object is returned with the following properties:
+
+* `source`: The original source file, or null if this information is not
+  available.
+
+* `line`: The line number in the original source, or null if this information is
+  not available.
+
+* `column`: The column number in the original source, or null or null if this
+  information is not available.
+
+* `name`: The original identifier, or null if this information is not available.
+
+#### SourceMapConsumer.prototype.generatedPositionFor(originalPosition)
+
+Returns the generated line and column information for the original source,
+line, and column positions provided. The only argument is an object with
+the following properties:
+
+* `source`: The filename of the original source.
+
+* `line`: The line number in the original source.
+
+* `column`: The column number in the original source.
+
+and an object is returned with the following properties:
+
+* `line`: The line number in the generated source, or null.
+
+* `column`: The column number in the generated source, or null.
+
+#### SourceMapConsumer.prototype.allGeneratedPositionsFor(originalPosition)
+
+Returns all generated line and column information for the original source
+and line provided. The only argument is an object with the following
+properties:
+
+* `source`: The filename of the original source.
+
+* `line`: The line number in the original source.
+
+and an array of objects is returned, each with the following properties:
+
+* `line`: The line number in the generated source, or null.
+
+* `column`: The column number in the generated source, or null.
+
+#### SourceMapConsumer.prototype.sourceContentFor(source)
+
+Returns the original source content for the source provided. The only
+argument is the URL of the original source file.
+
+#### SourceMapConsumer.prototype.eachMapping(callback, context, order)
+
+Iterate over each mapping between an original source/line/column and a
+generated line/column in this source map.
+
+* `callback`: The function that is called with each mapping. Mappings have the
+  form `{ source, generatedLine, generatedColumn, originalLine, originalColumn,
+  name }`
+
+* `context`: Optional. If specified, this object will be the value of `this`
+  every time that `callback` is called.
+
+* `order`: Either `SourceMapConsumer.GENERATED_ORDER` or
+  `SourceMapConsumer.ORIGINAL_ORDER`. Specifies whether you want to iterate over
+  the mappings sorted by the generated file's line/column order or the
+  original's source/line/column order, respectively. Defaults to
+  `SourceMapConsumer.GENERATED_ORDER`.
+
+### SourceMapGenerator
+
+An instance of the SourceMapGenerator represents a source map which is being
+built incrementally.
+
+#### new SourceMapGenerator([startOfSourceMap])
+
+You may pass an object with the following properties:
+
+* `file`: The filename of the generated source that this source map is
+  associated with.
+
+* `sourceRoot`: A root for all relative URLs in this source map.
+
+* `skipValidation`: Optional. When `true`, disables validation of mappings as
+  they are added. This can improve performance but should be used with
+  discretion, as a last resort. Even then, one should avoid using this flag when
+  running tests, if possible.
+
+#### SourceMapGenerator.fromSourceMap(sourceMapConsumer)
+
+Creates a new SourceMapGenerator based on a SourceMapConsumer
+
+* `sourceMapConsumer` The SourceMap.
+
+#### SourceMapGenerator.prototype.addMapping(mapping)
+
+Add a single mapping from original source line and column to the generated
+source's line and column for this source map being created. The mapping object
+should have the following properties:
+
+* `generated`: An object with the generated line and column positions.
+
+* `original`: An object with the original line and column positions.
+
+* `source`: The original source file (relative to the sourceRoot).
+
+* `name`: An optional original token name for this mapping.
+
+#### SourceMapGenerator.prototype.setSourceContent(sourceFile, sourceContent)
+
+Set the source content for an original source file.
+
+* `sourceFile` the URL of the original source file.
+
+* `sourceContent` the content of the source file.
+
+#### SourceMapGenerator.prototype.applySourceMap(sourceMapConsumer[, sourceFile[, sourceMapPath]])
+
+Applies a SourceMap for a source file to the SourceMap.
+Each mapping to the supplied source file is rewritten using the
+supplied SourceMap. Note: The resolution for the resulting mappings
+is the minimium of this map and the supplied map.
+
+* `sourceMapConsumer`: The SourceMap to be applied.
+
+* `sourceFile`: Optional. The filename of the source file.
+  If omitted, sourceMapConsumer.file will be used, if it exists.
+  Otherwise an error will be thrown.
+
+* `sourceMapPath`: Optional. The dirname of the path to the SourceMap
+  to be applied. If relative, it is relative to the SourceMap.
+
+  This parameter is needed when the two SourceMaps aren't in the same
+  directory, and the SourceMap to be applied contains relative source
+  paths. If so, those relative source paths need to be rewritten
+  relative to the SourceMap.
+
+  If omitted, it is assumed that both SourceMaps are in the same directory,
+  thus not needing any rewriting. (Supplying `'.'` has the same effect.)
+
+#### SourceMapGenerator.prototype.toString()
+
+Renders the source map being generated to a string.
+
+### SourceNode
+
+SourceNodes provide a way to abstract over interpolating and/or concatenating
+snippets of generated JavaScript source code, while maintaining the line and
+column information associated between those snippets and the original source
+code. This is useful as the final intermediate representation a compiler might
+use before outputting the generated JS and source map.
+
+#### new SourceNode([line, column, source[, chunk[, name]]])
+
+* `line`: The original line number associated with this source node, or null if
+  it isn't associated with an original line.
+
+* `column`: The original column number associated with this source node, or null
+  if it isn't associated with an original column.
+
+* `source`: The original source's filename; null if no filename is provided.
+
+* `chunk`: Optional. Is immediately passed to `SourceNode.prototype.add`, see
+  below.
+
+* `name`: Optional. The original identifier.
+
+#### SourceNode.fromStringWithSourceMap(code, sourceMapConsumer[, relativePath])
+
+Creates a SourceNode from generated code and a SourceMapConsumer.
+
+* `code`: The generated code
+
+* `sourceMapConsumer` The SourceMap for the generated code
+
+* `relativePath` The optional path that relative sources in `sourceMapConsumer`
+  should be relative to.
+
+#### SourceNode.prototype.add(chunk)
+
+Add a chunk of generated JS to this source node.
+
+* `chunk`: A string snippet of generated JS code, another instance of
+   `SourceNode`, or an array where each member is one of those things.
+
+#### SourceNode.prototype.prepend(chunk)
+
+Prepend a chunk of generated JS to this source node.
+
+* `chunk`: A string snippet of generated JS code, another instance of
+   `SourceNode`, or an array where each member is one of those things.
+
+#### SourceNode.prototype.setSourceContent(sourceFile, sourceContent)
+
+Set the source content for a source file. This will be added to the
+`SourceMap` in the `sourcesContent` field.
+
+* `sourceFile`: The filename of the source file
+
+* `sourceContent`: The content of the source file
+
+#### SourceNode.prototype.walk(fn)
+
+Walk over the tree of JS snippets in this node and its children. The walking
+function is called once for each snippet of JS and is passed that snippet and
+the its original associated source's line/column location.
+
+* `fn`: The traversal function.
+
+#### SourceNode.prototype.walkSourceContents(fn)
+
+Walk over the tree of SourceNodes. The walking function is called for each
+source file content and is passed the filename and source content.
+
+* `fn`: The traversal function.
+
+#### SourceNode.prototype.join(sep)
+
+Like `Array.prototype.join` except for SourceNodes. Inserts the separator
+between each of this source node's children.
+
+* `sep`: The separator.
+
+#### SourceNode.prototype.replaceRight(pattern, replacement)
+
+Call `String.prototype.replace` on the very right-most source snippet. Useful
+for trimming whitespace from the end of a source node, etc.
+
+* `pattern`: The pattern to replace.
+
+* `replacement`: The thing to replace the pattern with.
+
+#### SourceNode.prototype.toString()
+
+Return the string representation of this source node. Walks over the tree and
+concatenates all the various snippets together to one string.
+
+#### SourceNode.prototype.toStringWithSourceMap([startOfSourceMap])
+
+Returns the string representation of this tree of source nodes, plus a
+SourceMapGenerator which contains all the mappings between the generated and
+original sources.
+
+The arguments are the same as those to `new SourceMapGenerator`.
+
+## Tests
+
+[![Build Status](https://travis-ci.org/mozilla/source-map.png?branch=master)](https://travis-ci.org/mozilla/source-map)
+
+Install NodeJS version 0.8.0 or greater, then run `node test/run-tests.js`.
+
+To add new tests, create a new file named `test/test-<your new test name>.js`
+and export your test functions with names that start with "test", for example
+
+    exports["test doing the foo bar"] = function (assert, util) {
+      ...
+    };
+
+The new test will be located automatically when you run the suite.
+
+The `util` argument is the test utility module located at `test/source-map/util`.
+
+The `assert` argument is a cut down version of node's assert module. You have
+access to the following assertion functions:
+
+* `doesNotThrow`
+
+* `equal`
+
+* `ok`
+
+* `strictEqual`
+
+* `throws`
+
+(The reason for the restricted set of test functions is because we need the
+tests to run inside Firefox's test suite as well and so the assert module is
+shimmed in that environment. See `build/assert-shim.js`.)
