-# 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.

-
-Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
-Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
-
-In addition to negotiator, it allows:
-
-- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
-  as well as `('text/html', 'application/json')`.
-- Allows type shorthands such as `json`.
-- Returns `false` when no types match
-- Treats non-existent headers as `*`
-
-## Installation
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install accepts
-```
-
-## API
-
-<!-- eslint-disable no-unused-vars -->
-
-```js
-var accepts = require('accepts')
-```
-
-### accepts(req)
-
-Create a new `Accepts` object for the given `req`.
-
-#### .charset(charsets)
-
-Return the first accepted charset. If nothing in `charsets` is accepted,
-then `false` is returned.
-
-#### .charsets()
-
-Return the charsets that the request accepts, in the order of the client's
-preference (most preferred first).
-
-#### .encoding(encodings)
-
-Return the first accepted encoding. If nothing in `encodings` is accepted,
-then `false` is returned.
-
-#### .encodings()
-
-Return the encodings that the request accepts, in the order of the client's
-preference (most preferred first).
-
-#### .language(languages)
-
-Return the first accepted language. If nothing in `languages` is accepted,
-then `false` is returned.
-
-#### .languages()
-
-Return the languages that the request accepts, in the order of the client's
-preference (most preferred first).
-
-#### .type(types)
-
-Return the first accepted type (and it is returned as the same text as what
-appears in the `types` array). If nothing in `types` is accepted, then `false`
-is returned.
-
-The `types` array can contain full MIME types or file extensions. Any value
-that is not a full MIME types is passed to `require('mime-types').lookup`.
-
-#### .types()
-
-Return the types that the request accepts, in the order of the client's
-preference (most preferred first).
-
-## Examples
-
-### Simple type negotiation
-
-This simple example shows how to use `accepts` to return a different typed
-respond body based on what the client wants to accept. The server lists it's
-preferences in order and will get back the best match between the client and
-server.
-
-```js
-var accepts = require('accepts')
-var http = require('http')
-
-function app (req, res) {
-  var accept = accepts(req)
-
-  // the order of this list is significant; should be server preferred order
-  switch (accept.type(['json', 'html'])) {
-    case 'json':
-      res.setHeader('Content-Type', 'application/json')
-      res.write('{"hello":"world!"}')
-      break
-    case 'html':
-      res.setHeader('Content-Type', 'text/html')
-      res.write('<b>hello, world!</b>')
-      break
-    default:
-      // the fallback is text/plain, so no need to specify it above
-      res.setHeader('Content-Type', 'text/plain')
-      res.write('hello, world!')
-      break
-  }
-
-  res.end()
-}
-
-http.createServer(app).listen(3000)
-```
-
-You can test this out with the cURL program:
-```sh
-curl -I -H'Accept: text/html' http://localhost:3000/
-```

-# 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.

-// 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.
