-# abbrev-js
-
-Just like [ruby's Abbrev](http://apidock.com/ruby/Abbrev).
-
-Usage:
-
- var abbrev = require("abbrev");
- abbrev("foo", "fool", "folding", "flop");
-
- // returns:
- { fl: 'flop'
- , flo: 'flop'
- , flop: 'flop'
- , fol: 'folding'
- , fold: 'folding'
- , foldi: 'folding'
- , foldin: 'folding'
- , folding: 'folding'
- , foo: 'foo'
- , fool: 'fool'
- }
-
-This is handy for command-line scripts, or other cases where you want to be able to accept shorthands.

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

-environment.
-
-Properly reject shorthand properties whose name is a keyword.
-
-Don't crash when the loose parser is called without options object.

-way non-critical errors are handled.
-
-## 2.7.0 (2016-01-04)
-
-### Fixes
-
-Stop allowing rest parameters in setters.
-
-Make sure the loose parser always attaches a `local` property to
-`ImportNamespaceSpecifier` nodes.
-
-Disallow `y` rexexp flag in ES5.
-
-Disallow `\00` and `\000` escapes in strict mode.
-
-Raise an error when an import name is a reserved word.

-Support parsing stdin in command-line tool.
-
-## 2.5.2 (2015-10-27)
-
-### Fixes
-
-Fix bug where the walker walked an exported `let` statement as an
-expression.
-
-## 2.5.0 (2015-10-27)
-
-### Fixes
-

-# Acorn
-
-[](https://travis-ci.org/ternjs/acorn)
-[](https://www.npmjs.com/package/acorn)
-[Author funding status: ](https://marijnhaverbeke.nl/fund/)
-
-A tiny, fast JavaScript parser, written completely in JavaScript.
-
-## Community
-
-Acorn is open source software released under an
-[MIT license](https://github.com/ternjs/acorn/blob/master/LICENSE).
-
-You are welcome to
-[report bugs](https://github.com/ternjs/acorn/issues) or create pull
-requests on [github](https://github.com/ternjs/acorn). For questions
-and discussion, please use the
-[Tern discussion forum](https://discuss.ternjs.net).
-
-## Installation
-
-The easiest way to install acorn is with [`npm`][npm].
-
-[npm]: https://www.npmjs.com/
-
-```sh
-npm install acorn
-```
-
-Alternately, download the source.
-
-```sh
-git clone https://github.com/ternjs/acorn.git
-```
-
-## Components
-
-When run in a CommonJS (node.js) or AMD environment, exported values
-appear in the interfaces exposed by the individual files, as usual.
-When loaded in the browser (Acorn works in any JS-enabled browser more
-recent than IE5) without any kind of module management, a single
-global object `acorn` will be defined, and all the exported properties
-will be added to that.
-
-### Main parser
-
-This is implemented in `dist/acorn.js`, and is what you get when you
-`require("acorn")` in node.js.
-
-**parse**`(input, options)` is used to parse a JavaScript program.
-The `input` parameter is a string, `options` can be undefined or an
-object setting some of the options listed below. The return value will
-be an abstract syntax tree object as specified by the
-[ESTree spec][estree].
-
-When encountering a syntax error, the parser will raise a
-`SyntaxError` object with a meaningful message. The error object will
-have a `pos` property that indicates the character offset at which the
-error occurred, and a `loc` object that contains a `{line, column}`
-object referring to that same position.

-- **ecmaVersion**: Indicates the ECMAScript version to parse. Must be
- either 3, 5, 6, or 7. This influences support for strict mode, the set
- of reserved words, and support for new syntax features. Default is 6.
-
- **NOTE**: Only 'stage 4' (finalized) ECMAScript 7 features are being
- implemented by Acorn. That means that most of the draft standard is
- not yet being parsed.
-
-- **sourceType**: Indicate the mode the code should be parsed in. Can be
- either `"script"` or `"module"`.
-
-- **onInsertedSemicolon**: If given a callback, that callback will be
- called whenever a missing semicolon is inserted by the parser. The
- callback will be given the character offset of the point where the
- semicolon is inserted as argument, and if `locations` is on, also a
- `{line, column}` object representing this position.
-
-- **onTrailingComma**: Like `onInsertedSemicolon`, but for trailing
- commas.
-
-- **allowReserved**: If `false`, using a reserved word will generate
- an error. Defaults to `true` for `ecmaVersion` 3, `false` for higher
- versions. When given the value `"never"`, reserved words and
- keywords can also not be used as property names (as in Internet
- Explorer's old parser).
-
-- **allowReturnOutsideFunction**: By default, a return statement at
- the top level raises an error. Set this to `true` to accept such
- code.
-
-- **allowImportExportEverywhere**: By default, `import` and `export`
- declarations can only appear at a program's top level. Setting this
- option to `true` allows them anywhere where a statement is allowed.
-
-- **allowHashBang**: When this is enabled (off by default), if the
- code starts with the characters `#!` (as in a shellscript), the
- first line will be treated as a comment.
-
-- **locations**: When `true`, each node has a `loc` object attached
- with `start` and `end` subobjects, each of which contains the
- one-based line and zero-based column numbers in `{line, column}`
- form. Default is `false`.
-
-- **onToken**: If a function is passed for this option, each found
- token will be passed in same format as tokens returned from
- `tokenizer().getToken()`.
-
- If array is passed, each found token is pushed to it.
-
- Note that you are not allowed to call the parser from the
- callback—that will corrupt its internal state.
-
-- **onComment**: If a function is passed for this option, whenever a
- comment is encountered the function will be called with the
- following parameters:
-
- - `block`: `true` if the comment is a block comment, false if it
- is a line comment.
- - `text`: The content of the comment.
- - `start`: Character offset of the start of the comment.
- - `end`: Character offset of the end of the comment.
-
- When the `locations` options is on, the `{line, column}` locations
- of the comment’s start and end are passed as two additional
- parameters.
-
- If array is passed for this option, each found comment is pushed
- to it as object in Esprima format:
-
- ```javascript
- {
- "type": "Line" | "Block",
- "value": "comment text",
- "start": Number,
- "end": Number,
- // If `locations` option is on:
- "loc": {
- "start": {line: Number, column: Number}
- "end": {line: Number, column: Number}
- },
- // If `ranges` option is on:
- "range": [Number, Number]
- }
- ```
-
- Note that you are not allowed to call the parser from the
- callback—that will corrupt its internal state.
-
-- **ranges**: Nodes have their start and end characters offsets
- recorded in `start` and `end` properties (directly on the node,
- rather than the `loc` object, which holds line/column data. To also
- add a [semi-standardized][range] `range` property holding a
- `[start, end]` array with the same numbers, set the `ranges` option
- to `true`.
-
-- **program**: It is possible to parse multiple files into a single
- AST by passing the tree produced by parsing the first file as the
- `program` option in subsequent parses. This will add the toplevel
- forms of the parsed file to the "Program" (top) node of an existing
- parse tree.
-
-- **sourceFile**: When the `locations` option is `true`, you can pass
- this option to add a `source` attribute in every node’s `loc`
- object. Note that the contents of this option are not examined or
- processed in any way; you are free to use whatever format you
- choose.
-
-- **directSourceFile**: Like `sourceFile`, but a `sourceFile` property
- will be added (regardless of the `location` option) directly to the
- nodes, rather than the `loc` object.
-
-- **preserveParens**: If this option is `true`, parenthesized expressions
- are represented by (non-standard) `ParenthesizedExpression` nodes
- that have a single `expression` property containing the expression
- inside parentheses.
-
-[range]: https://bugzilla.mozilla.org/show_bug.cgi?id=745678
-
-**parseExpressionAt**`(input, offset, options)` will parse a single
-expression in a string, and return its AST. It will not complain if
-there is more of the string left after the expression.
-
-**getLineInfo**`(input, offset)` can be used to get a `{line,
-column}` object for a given program string and character offset.
-
-**tokenizer**`(input, options)` returns an object with a `getToken`
-method that can be called repeatedly to get the next token, a `{start,
-end, type, value}` object (with added `loc` property when the
-`locations` option is enabled and `range` property when the `ranges`
-option is enabled). When the token's type is `tokTypes.eof`, you
-should stop calling the method, since it will keep returning that same
-token forever.
-
-In ES6 environment, returned result can be used as any other
-protocol-compliant iterable:
-
-```javascript
-for (let token of acorn.tokenizer(str)) {
- // iterate over the tokens
-}
-
-// transform code to array of tokens:
-var tokens = [...acorn.tokenizer(str)];
-```
-
-**tokTypes** holds an object mapping names to the token type objects
-that end up in the `type` properties of tokens.
-
-#### Note on using with [Escodegen][escodegen]
-
-Escodegen supports generating comments from AST, attached in
-Esprima-specific format. In order to simulate same format in
-Acorn, consider following example:
-
-```javascript
-var comments = [], tokens = [];
-
-var ast = acorn.parse('var x = 42; // answer', {
- // collect ranges for each node
- ranges: true,
- // collect comments in Esprima's format
- onComment: comments,
- // collect token ranges
- onToken: tokens
-});
-
-// attach comments using collected information
-escodegen.attachComments(ast, comments, tokens);
-
-// generate code
-console.log(escodegen.generate(ast, {comment: true}));
-// > 'var x = 42; // answer'
-```

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

-// ## Token types
-
-// The assignment of fine-grained, information-carrying type objects
-// allows the tokenizer to store the information it has about a
-// token in a way that is very cheap for the parser to look up.
-
-// All token type variables start with an underscore, to make them
-// easy to recognize.
-
-// The `beforeExpr` property is used to disambiguate between regular
-// expressions and divisions. It is set on all token types that can
-// be followed by an expression (thus, a slash after them would be a
-// regular expression).

-// and provide reference for storing '=' operator inside shorthand

-// 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

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

-
-Solve spurious parenthesized pattern errors by temporarily erring on
-the side of accepting programs that our delayed errors don't handle
-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.
-

-
-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)
-
-### Breaking changes
-
-The default `ecmaVersion` option value is now 7.
-
-A number of internal method signatures changed, so plugins might need
-to be updated.
-
-### Bug fixes
-
-The parser now raises errors on duplicated export names.
-
-`arguments` and `eval` can now be used in shorthand properties.
-
-Duplicate parameter names in non-simple argument lists now always
-produce an error.
-

-(2015, etc).
-
-Support for `async`/`await` syntax when `ecmaVersion` is >= 8.
-
-Support for trailing commas in call expressions when `ecmaVersion`
-is >= 8.
-
-## 3.3.0 (2016-07-25)

-
-Fix parser crash when parsing an array pattern with a hole.
-
-### New features
-
-Implement check against complex argument lists in functions that
-enable strict mode in ES7.
-
-## 3.2.0 (2016-06-07)
-
-### Bug fixes
-
-Improve handling of lack of unicode regexp support in host
-environment.
-
-Properly reject shorthand properties whose name is a keyword.
-
-Don't crash when the loose parser is called without options object.
-
-### New features
-
-Visitors created with `visit.make` now have their base as _prototype_,
-rather than copying properties into a fresh object.
-
-Make it possible to use `visit.ancestor` with a walk state.
-
-## 3.1.0 (2016-04-18)
-
-### Bug fixes
-
-Fix issue where the loose parser created invalid TemplateElement nodes
-for unclosed template literals.
-
-Properly tokenize the division operator directly after a function
-expression.
-
-Allow trailing comma in destructuring arrays.
-
-### New features
-

-
-### Fixes
-
-Fix bug that accidentally made `undefined` a reserved word when
-parsing ES7.
-
-## 3.0.0 (2016-02-10)
-
-### Breaking changes
-

-
-Support for comprehension syntax (which was dropped from the draft
-spec) has been removed.
-
-### Fixes

-
-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
-operator (`**`).
-
-The identifier character ranges are now based on Unicode 8.0.0.
-
-Plugins can now override the `raiseRecoverable` method to override the
-way non-critical errors are handled.
-
-## 2.7.0 (2016-01-04)
-
-### Fixes
-
-Stop allowing rest parameters in setters.
-
-Make sure the loose parser always attaches a `local` property to
-`ImportNamespaceSpecifier` nodes.
-
-Disallow `y` rexexp flag in ES5.
-

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

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