# 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.
module.exports = exports = abbrev.abbrev = abbrev
abbrev.monkeyPatch = monkeyPatch
function monkeyPatch () {
Object.defineProperty(Array.prototype, 'abbrev', {
value: function () { return abbrev(this) },
enumerable: false, configurable: true, writable: true
})
Object.defineProperty(Object.prototype, 'abbrev', {
value: function () { return abbrev(Object.keys(this)) },
enumerable: false, configurable: true, writable: true
})
}
function abbrev (list) {
if (arguments.length !== 1 || !Array.isArray(list)) {
list = Array.prototype.slice.call(arguments, 0)
}
for (var i = 0, l = list.length, args = [] ; i < l ; i ++) {
args[i] = typeof list[i] === "string" ? list[i] : String(list[i])
}
// sort them lexicographically, so that they're next to their nearest kin
args = args.sort(lexSort)
// walk through each, seeing how much it has in common with the next and previous
var abbrevs = {}
, prev = ""
for (var i = 0, l = args.length ; i < l ; i ++) {
var current = args[i]
, next = args[i + 1] || ""
, nextMatches = true
, prevMatches = true
if (current === next) continue
for (var j = 0, cl = current.length ; j < cl ; j ++) {
var curChar = current.charAt(j)
nextMatches = nextMatches && curChar === next.charAt(j)
prevMatches = prevMatches && curChar === prev.charAt(j)
if (!nextMatches && !prevMatches) {
j ++
break
}
}
prev = current
if (j === cl) {
abbrevs[current] = current
continue
}
for (var a = current.substr(0, j) ; j <= cl ; j ++) {
abbrevs[a] = current
a += current.charAt(j)
}
}
return abbrevs
}
function lexSort (a, b) {
return a === b ? 0 : a > b ? 1 : -1

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

## 3.3.0 (2016-07-25)
### Bug fixes
Fix bug in tokenizing of regexp operator after a function declaration.
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
The walker now allows defining handlers for `CatchClause` nodes.
## 3.0.4 (2016-02-25)
### Fixes
Allow update expressions as left-hand-side of the ES7 exponential
operator.
## 3.0.2 (2016-02-10)
### Fixes
Fix bug that accidentally made `undefined` a reserved word when
parsing ES7.
## 3.0.0 (2016-02-10)
### Breaking changes
The default value of the `ecmaVersion` option is now 6 (used to be 5).
Support for comprehension syntax (which was dropped from the draft
spec) has been removed.
### Fixes
`let` and `yield` are now “contextual keywords”, meaning you can
mostly use them as identifiers in ES5 non-strict code.
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.
Disallow `\00` and `\000` escapes in strict mode.
Raise an error when an import name is a reserved word.
## 2.6.4 (2015-11-12)
### Fixes
Fix crash in loose parser when parsing invalid object pattern.
### New features
Support plugins in the loose parser.
## 2.6.2 (2015-11-10)
### Fixes
Don't crash when no options object is passed.
## 2.6.0 (2015-11-09)
### Fixes
Add `await` as a reserved word in module sources.
Disallow `yield` in a parameter default value for a generator.
Forbid using a comma after a rest pattern in an array destructuring.
### New features
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
Fix tokenizer support in the command-line tool.
In the loose parser, don't allow non-string-literals as import
sources.
Stop allowing `new.target` outside of functions.
Remove legacy `guard` and `guardedHandler` properties from try nodes.
Stop allowing multiple `__proto__` properties on an object literal in
strict mode.
Don't allow rest parameters to be non-identifier patterns.
Check for duplicate paramter names in arrow functions.

// 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.

## 5.2.1 (2017-10-30)
### Bug fixes
Fix a token context corruption bug.
## 5.2.0 (2017-10-30)
### Bug fixes
Fix token context tracking for `class` and `function` in property-name position.
Make sure `%*` isn't parsed as a valid operator.
The `full` and `fullAncestor` walkers no longer visit nodes multiple times.
Allow shorthand properties `get` and `set` to be followed by default values.
Disallow `super` when not in callee or object position.
### New features
Support [`directive` property](https://github.com/estree/estree/compare/b3de58c9997504d6fba04b72f76e6dd1619ee4eb...1da8e603237144f44710360f8feb7a9977e905e0) on directive expression statements.
## 5.1.2 (2017-09-04)
### Bug fixes
Disable parsing of legacy HTML-style comments in modules.
Fix parsing of async methods whose names are keywords.
## 5.1.1 (2017-07-06)
### Bug fixes
Fix problem with disambiguating regexp and division after a class.
## 5.1.0 (2017-07-05)
### Bug fixes
Fix tokenizing of regexps in an object-desctructuring `for`/`of` loop and after `yield`.
Parse zero-prefixed numbers with non-octal digits as decimal.
Allow object/array patterns in rest parameters.
Don't error when `yield` is used as a property name.
Allow `async` as a shorthand object property.
Make the ES module version of the loose parser actually work.
### New features
Implement the [template literal revision proposal](https://github.com/tc39/proposal-template-literal-revision) for ES9.
New walker functions `full` and `fullAncestor`.
## 5.0.3 (2017-04-01)
### Bug fixes
Fix spurious duplicate variable definition errors for named functions.
## 5.0.2 (2017-03-30)
### Bug fixes
A binary operator after a parenthesized arrow expression is no longer incorrectly treated as an error.
## 5.0.0 (2017-03-28)
### Bug fixes
Raise an error for duplicated lexical bindings.
Fix spurious error when an assignement expression occurred after a spread expression.
Accept regular expressions after `of` (in `for`/`of`), `yield` (in a generator), and braced arrow functions.
Allow labels in front or `var` declarations, even in strict mode.
### Breaking changes
Parse declarations following `export default` as declaration nodes, not expressions. This means that class and function declarations nodes can now have `null` as their `id`.
## 4.0.11 (2017-02-07)
### Bug fixes
Allow all forms of member expressions to be parenthesized as lvalue.
## 4.0.10 (2017-02-07)
### Bug fixes
Don't expect semicolons after default-exported functions or classes,
even when they are expressions.
Check for use of `'use strict'` directives in non-simple parameter
functions, even when already in strict mode.
## 4.0.9 (2017-02-06)
### Bug fixes
Fix incorrect error raised for parenthesized simple assignment
targets, so that `(x) = 1` parses again.
## 4.0.8 (2017-02-03)
### Bug fixes
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.
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.
Disallow labeled declarations.
## 4.0.4 (2016-12-19)
### Bug fixes
Fix issue with loading acorn_loose.js with an AMD loader.
Fix crash when `export` was followed by a keyword that can't be
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)
### 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.
### New features
The `ecmaVersion` option now also accepts year-style version numbers
(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)
### Bug fixes
Fix bug in tokenizing of regexp operator after a function declaration.
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
The walker now allows defining handlers for `CatchClause` nodes.
## 3.0.4 (2016-02-25)
### Fixes
Allow update expressions as left-hand-side of the ES7 exponential
operator.
## 3.0.2 (2016-02-10)
### Fixes
Fix bug that accidentally made `undefined` a reserved word when
parsing ES7.
## 3.0.0 (2016-02-10)
### Breaking changes
The default value of the `ecmaVersion` option is now 6 (used to be 5).
Support for comprehension syntax (which was dropped from the draft
spec) has been removed.
### Fixes
`let` and `yield` are now “contextual keywords”, meaning you can
mostly use them as identifiers in ES5 non-strict code.
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.
Disallow `\00` and `\000` escapes in strict mode.
Raise an error when an import name is a reserved word.
## 2.6.4 (2015-11-12)
### Fixes
Fix crash in loose parser when parsing invalid object pattern.
### New features
Support plugins in the loose parser.
