Sometimes it's called a "filter", +// but that's not a great name for it, since that implies a thing where +// some bits pass through, and others are simply ignored. (That would +// be a valid example of a transform, of course.) +// +// While the output is causally related to the input, it's not a +// necessarily symmetric or synchronous transformation. For example, +// a zlib stream might take multiple plain-text writes(), and then +// emit a single compressed chunk some time in the future. +// +// Here's how this works: +// +// The Transform stream has all the aspects of the readable and writable +// stream classes. When you write(chunk), that calls _write(chunk,cb) +// internally, and returns false if there's a lot of pending writes +// buffered up. When you call read(), that calls _read(n) until +// there's enough pending readable data buffered up. +// +// In a transform stream, the written data is placed in a buffer. When +// _read(n) is called, it transforms the queued up data, calling the +// buffered _write cb's as it consumes chunks. If consuming a single +// written chunk would result in multiple output chunks, then the first +// outputted bit calls the readcb, and subsequent chunks just go into +// the read buffer, and will cause it to emit 'readable' if necessary. +// +// This way, back-pressure is actually determined by the reading side, +// since _read has to be called to start processing a new chunk. However, +// a pathological inflate type of transform can cause excessive buffering +// here. For example, imagine a stream where every byte of input is +// interpreted as an integer from 0-255, and then results in that many +// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in +// 1kb of data being output. In this case, you could write a very small +// amount of input, and end up with a very large amount of output. In +// such a pathological inflating mechanism, there'd be no way to tell +// the system to stop doing the transform. A single 4MB write could +// cause the system to run out of memory. +// +// However, even in such a pathological case, only a single written chunk +// would be consumed, and then the rest would wait (un-transformed) until +// the results of the previous transformed chunk were consumed. + +'use strict'; + +module.exports = Transform; + +var Duplex = require('./_stream_duplex'); + +/**/ +var util = require('core-util-is'); +util.inherits = require('inherits'); +/**/ + +util.inherits(Transform, Duplex); + +function TransformState(stream) { + this.afterTransform = function (er, data) { + return afterTransform(stream, er, data); + }; + + this.needTransform = false; + this.transforming = false; + this.writecb = null; + this.writechunk = null; + this.writeencoding = null; +} + +function afterTransform(stream, er, data) { + var ts = stream._transformState; + ts.transforming = false; + + var cb = ts.writecb; + + if (!cb) { + return stream.emit('error', new Error('write callback called multiple times')); + } + + ts.writechunk = null; + ts.writecb = null; + + if (data !== null && data !== undefined) stream.push(data); + + cb(er); + + var rs = stream._readableState; + rs.reading = false; + if (rs.needReadable || rs.length < rs.highWaterMark) { + stream._read(rs.highWaterMark); + } +} + +function Transform(options) { + if (!(this instanceof Transform)) return new Transform(options); + + Duplex.call(this, options); + + this._transformState = new TransformState(this); + + var stream = this; + + // start out asking for a readable event once data is transformed. + this._readableState.needReadable = true; + + // we have implemented the _read method, and done the other things + // that Readable wants before the first _read call, so unset the + // sync guard flag. + this._readableState.sync = false; + + if (options) { + if (typeof options.transform === 'function') this._transform = options.transform; + + if (typeof options.flush === 'function') this._flush = options.flush; + } + + // When the writable side finishes, then flush out anything remaining. + this.once('prefinish', function () { + if (typeof this._flush === 'function') this._flush(function (er, data) { + done(stream, er, data); + });else done(stream); + }); +} + +Transform.prototype.push = function (chunk, encoding) { + this._transformState.needTransform = false; + return Duplex.prototype.push.call(this, chunk, encoding); +}; + +// This is the part where you do stuff! +// override this function in implementation classes. +// 'chunk' is an input chunk. +// +// Call `push(newChunk)` to pass along transformed output +// to the readable side.

If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output. ## Wildcards - The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect.compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`. +The `*` character may be used as a wildcard.

For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:". +__Note:__ The environment variables beginning with `DEBUG_` end up being +converted into an Options object that gets used with `%o`/`%O` formatters. +See the Node.js documentation for +[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options) +for the complete list. -## Browser support +## Formatters - Debug works in the browser as well, currently persisted by `localStorage`. For example if you have `worker:a` and `worker:b` as shown below, and wish to debug both type `debug.enable('worker:*')` in the console and refresh the page, this will remain until you disable with `debug.disable()`. +Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. +Below are the officially supported formatters: + +| Formatter | Representation | +|-----------|----------------| +| `%O` | Pretty-print an Object on multiple lines. | +| `%o` | Pretty-print an Object all on a single line. | +| `%s` | String. | +| `%d` | Number (both integer and float). | +| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. | +| `%%` | Single percent sign ('%'). This does not consume an argument. | + + +### Custom formatters + +You can add custom formatters by extending the `debug.formatters` object. +For example, if you wanted to add support for rendering a Buffer as hex with +`%h`, you could do something like: + +```js +const createDebug = require('debug') +createDebug.formatters.h = (v) => { + return v.toString('hex') +} + +// …elsewhere +const debug = createDebug('foo') +debug('this is hex: %h', new Buffer('hello world')) +// foo this is hex: 68656c6c6f20776f726c6421 +0ms +``` + + +## Browser Support + +You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify), +or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest), +if you don't want to build it yourself. + +Debug's enable state is currently persisted by `localStorage`. +Consider the situation shown below where you have `worker:a` and `worker:b`, +and wish to debug both.

-# Growl for nodejs
-
-Growl support for Nodejs. This is essentially a port of my [Ruby Growl Library](http://github.com/visionmedia/growl).  Ubuntu/Linux support added thanks to [@niftylettuce](http://github.com/niftylettuce). You'll need [growlnotify(1)](http://growl.info/extras.php#growlnotify).
-
-## Installation
-
-### Mac OS X (Darwin):
-
-  Install [npm](http://npmjs.org/) and run:
-  
-      $ npm install growl
-
-### Ubuntu (Linux):
-
-  Install `notify-send` through the [libnotify-bin](http://packages.ubuntu.com/libnotify-bin) package:
-
-      $ sudo apt-get install libnotify-bin
-
-  Install [npm](http://npmjs.org/) and run:
-  
-      $ npm install growl
-
-### Windows:
-
-  Download and install [Growl for Windows](http://www.growlforwindows.com/gfw/default.aspx)
-
-  Download [growlnotify](http://www.growlforwindows.com/gfw/help/growlnotify.aspx) - **IMPORTANT :** Unpack growlnotify to a folder that is present in your path!
-
-  Install [npm](http://npmjs.org/) and run:
-  
-      $ npm install growl
-
-## Examples
-
-Callback functions are optional
-
-    var growl = require('growl')
-    growl('You have mail!')
-    growl('5 new messages', { sticky: true })
-    growl('5 new emails', { title: 'Email Client', image: 'Safari', sticky: true })
-    growl('Message with title', { title: 'Title'})
-    growl('Set priority', { priority: 2 })
-    growl('Show Safari icon', { image: 'Safari' })
-    growl('Show icon', { image: 'path/to/icon.icns' })
-    growl('Show image', { image: 'path/to/my.image.png' })
-    growl('Show png filesystem icon', { image: 'png' })
-    growl('Show pdf filesystem icon', { image: 'article.pdf' })
-    growl('Show pdf filesystem icon', { image: 'article.pdf' }, function(err){
-      // ... notified
-    })
-
-## Options
-
-  - title
-    - notification title
-  - name
-    - application name
-  - priority
-    - priority for the notification (default is 0)
-  - sticky
-    - weither or not the notification should remainin until closed
-  - image
-    - Auto-detects the context:
-      - path to an icon sets --iconpath
-      - path to an image sets --image
-      - capitalized word sets --appIcon
-      - filename uses extname as --icon
-      - otherwise treated as --icon

-# Jade
-
-  The jade template engine for node.js
-
-## Synopsis
-
-    jade [-h|--help] [-v|--version] [-o|--obj STR]
-         [-O|--out DIR] [-p|--path PATH] [-P|--pretty]
-         [-c|--client] [-D|--no-debug]
-
-## Examples
-
-  translate jade the templates dir
-
-    $ jade templates
-
-  create {foo,bar}.html
-
-    $ jade {foo,bar}.jade
-
-  jade over stdio
-
-    $ jade < my.jade > my.html
-
-  jade over s
-
-    $ echo "h1 Jade!" | jade
-
-  foo, bar dirs rendering to /tmp
-
-    $ jade foo bar --out /tmp
-
-  compile client-side templates without debugging
-  instrumentation, making the output javascript
-  very light-weight. This requires runtime.js
-  in your projects.
-
-     $ jade --client --no-debug < my.jade
-
-## Tags
-
-  Tags are simply nested via whitespace, closing
-  tags defined for you. These indents are called "blocks".
-  
-    ul
-      li
-        a Foo
-      li
-        a Bar
-
-  You may have several tags in one "block":
-  
-    ul
-      li
-        a Foo
-        a Bar
-        a Baz
-
-## Self-closing Tags
-
-  Some tags are flagged as self-closing by default, such
-  as `meta`, `link`, and so on. To explicitly self-close
-  a tag simply append the `/` character:
-
-     foo/
-     foo(bar='baz')/
-
-  Would yield:
-  
-     
-     
-
-## Attributes
-
-  Tag attributes look similar to HTML, however
-  the values are regular JavaScript, here are
-  some examples:
-  
-    a(href='google.com') Google
-    a(class='button', href='google.com') Google
-
-  As mentioned the attribute values are just JavaScript,
-  this means ternary operations and other JavaScript expressions
-  work just fine:
-  
-    body(class=user.authenticated ? 'authenticated' : 'anonymous')
-    a(href=user.website || 'http://google.com')
-
-  Multiple lines work too:
-
-    input(type='checkbox',
-      name='agreement',
-      checked)
-
-  Multiple lines without the comma work fine:
-
-    input(type='checkbox'
-      name='agreement'
-      checked)
-
-  Funky whitespace? fine:
-
-    input(
-      type='checkbox'
-      name='agreement'
-      checked)
-
-## Boolean attributes
-
-  Boolean attributes are mirrored by Jade, and accept
-  bools, aka _true_ or _false_. When no value is specified
-  _true_ is assumed. For example:
-  
-    input(type="checkbox", checked)
-    // => ""
-
-  For example if the checkbox was for an agreement, perhaps `user.agreed`
-  was _true_ the following would also output 'checked="checked"':
-  
-     input(type="checkbox", checked=user.agreed)
-
-## Class attributes
-
-  The _class_ attribute accepts an array of classes,
-  this can be handy when generated from a javascript
-  function etc:
-  
-    classes = ['foo', 'bar', 'baz']
-    a(class=classes)
-    // => ""
-
-## Class literal
-
-  Classes may be defined using a ".CLASSNAME" syntax:
-  
-     .button
-     // => "
            "
-  
-  Or chained:
-  
-     .large.button
-     // => "
            "
-
-  The previous defaulted to divs, however you
-  may also specify the tag type:
-  
-      h1.title My Title
-      // => "
            My Title
            "
-
-## Id literal
-
-  Much like the class literal there's an id literal:
-  
-    #user-1
-    // => "
            "
-
-  Again we may specify the tag as well:
-  
-    ul#menu
-      li: a(href='/home') Home
-      li: a(href='/store') Store
-      li: a(href='/contact') Contact
-
-  Finally all of these may be used in any combination,
-  the following are all valid tags:
-  
-    a.button#contact(style: 'color: red') Contact
-    a.button(style: 'color: red')#contact Contact
-    a(style: 'color: red').button#contact Contact
-
-## Block expansion
-
-  Jade supports the concept of "block expansion", in which
-  using a trailing ":" after a tag will inject a block:
-  
-    ul
-      li: a Foo
-      li: a Bar
-      li: a Baz
-
-## Text
-
-   Arbitrary text may follow tags:
-   
-     p Welcome to my site
-  
-  yields:
-  
-     
            Welcome to my site
            
-
-## Pipe text
-
-  Another form of text is "pipe" text. Pipes act
-  as the text margin for large bodies of text.
-
-    p
-      | This is a large
-      | body of text for
-      | this tag.
-      | 
-      | Nothing too
-      | exciting.
-
-  yields:
-  
-    
            This is a large
-    body of text for
-    this tag.
-
-    Nothing too
-    exciting.
-    
            
-
-  Using pipes we can also specify regular Jade tags
-  within the text:
-  
-    p
-      | Click to visit
-      a(href='http://google.com') Google
-      | if you want.
-
-## Text only tags
-
-  As an alternative to pipe text you may add
-  a trailing "." to indicate that the block
-  contains nothing but plain-text, no tags:
-
-    p.
-      This is a large
-      body of text for
-      this tag.
-
-      Nothing too
-      exciting.
-
-  Some tags are text-only by default, for example
-  _script_, _textarea_, and _style_ tags do not
-  contain nested HTML so Jade implies the trailing ".":
-  
-    script
-      if (foo) {
-        bar();
-      }
-
-    style
-      body {
-        padding: 50px;
-        font: 14px Helvetica;
-      }
-
-## Template script tags
-
-  Sometimes it's useful to define HTML in script
-  tags using Jade, typically for client-side templates.
-  
-  To do this simply give the _script_ tag an arbitrary
-  _type_ attribute such as _text/x-template_:
-  
-    script(type='text/template')
-      h1 Look!
-      p Jade still works in here!
-
-## Interpolation
-
-  Both plain-text and piped-text support interpolation,
-  which comes in two forms, escapes and non-escaped. The
-  following will output the _user.name_ in the paragraph
-  but HTML within it will be escaped to prevent XSS attacks:
-  
-    p Welcome #{user.name}
-
-  The following syntax is identical however it will _not_ escape
-  HTML, and should only be used with strings that you trust:
-  
-    p Welcome !{user.name}
-  
-## Inline HTML
-
-  Sometimes constructing small inline snippets of HTML
-  in Jade can be annoying, luckily we can add plain
-  HTML as well:
-  
-    p Welcome #{user.name}
-
-## Code
-
-  To buffer output with Jade simply use _=_ at the beginning
-  of a line or after a tag. This method escapes any HTML
-  present in the string.
-  
-    p= user.description
-    
-  To buffer output unescaped use the _!=_ variant, but again
-  be careful of XSS.
-  
-    p!= user.description
-  
-  The final way to mess with JavaScript code in Jade is the unbuffered
-  _-_, which can be used for conditionals, defining variables etc:
-  
-    - var user = { description: 'foo bar baz' }
-    #user
-      - if (user.description) {
-        h2 Description
-        p.description= user.description
-      - }
-
-   When compiled blocks are wrapped in anonymous functions, so the
-   following is also valid, without braces:
-   
-     - var user = { description: 'foo bar baz' }
-     #user
-       - if (user.description)
-         h2 Description
-         p.description= user.description
-
-   If you really want you could even use `.forEach()` and others:
-   
-    - users.forEach(function(user){
-      .user
-        h2= user.name
-        p User #{user.name} is #{user.age} years old
-    - })
-
-   Taking this further Jade provides some syntax for conditionals,
-   iteration, switch statements etc. Let's look at those next!
-
-## Assignment
-
-  Jade's first-class assignment is simple, simply use the _=_
-  operator and Jade will _var_ it for you. The following are equivalent:
-  
-    - var user = { name: 'tobi' }
-    user = { name: 'tobi' }
-
-## Conditionals
-
-  Jade's first-class conditional syntax allows for optional
-  parenthesis, and you may now omit the leading _-_ otherwise
-  it's identical, still just regular javascript:
-  
-    user = { description: 'foo bar baz' }
-    #user
-      if user.description
-        h2 Description
-        p.description= user.description
-
-  Jade provides the negated version, _unless_ as well, the following
-  are equivalent:
-  
-    - if (!(user.isAnonymous))
-      p You're logged in as #{user.name}
-
-    unless user.isAnonymous
-      p You're logged in as #{user.name}
-
-## Iteration
-
-  JavaScript's _for_ loops don't look very declarative, so Jade
-  also provides its own _for_ loop construct, aliased as _each_:
-
-    for user in users
-      .user
-        h2= user.name
-        p user #{user.name} is #{user.age} year old
-
-   As mentioned _each_ is identical:
-   
-     each user in users
-       .user
-         h2= user.name
-
-   If necessary the index is available as well:
-   
-      for user, i in users
-        .user(class='user-#{i}')
-          h2= user.name
-
-   Remember, it's just JavaScript:
-   
-      ul#letters
-        for letter in ['a', 'b', 'c']
-          li= letter
-
-## Mixins
-
-  Mixins provide a way to define jade "functions" which "mix in"
-  their contents when called. This is useful for abstracting
-  out large fragments of Jade.
-
-  The simplest possible mixin which accepts no arguments might
-  look like this:
-  
-      mixin hello
-        p Hello
-
-   You use a mixin by placing `+` before the name:
-
-      +hello
-
-   For something a little more dynamic, mixins can take
-   arguments, the mixin itself is converted to a javascript
-   function internally:
-   
-       mixin hello(user)
-         p Hello #{user}
-
-       +hello('Tobi')
-  
-   Yields:
-
-       
            Hello Tobi
            
-
-  Mixins may optionally take blocks, when a block is passed
-  its contents becomes the implicit `block` argument. For
-  example here is a mixin passed a block, and also invoked
-  without passing a block:
-
-      mixin article(title)
-        .article

-  Mixins can even take attributes, just like a tag. When
-  attributes are passed they become the implicit `attributes`
-  argument. Individual attributes can be accessed just like
-  normal object properties:
-  
-      mixin centered
-        .centered(class=attributes.class)
-          block
-      
-      +centered.bold Hello world
-      
-      +centered.red
-        p This is my
-        p Amazing article
-  
-   yields:
-   
-       
            Hello world
            
-       
            
-         
            This is my
            
-         
            Amazing article
            
-       
            
-  
-   If you use `attributes` directly, *all* passed attributes
-   get used:
-   
-      mixin link
-        a.menu(attributes)
-          block
-      
-      +link.highlight(href='#top') Top
-      +link#sec1.plain(href='#section1') Section 1
-      +link#sec2.plain(href='#section2') Section 2
-  
-   yields:
-   
-       Top
-       Section 1
-       Section 2
-   
-   If you pass arguments, they must directly follow the mixin:
-   
-      mixin list(arr)
-        if block
-          .title
-            block
-        ul(attributes)
-          each item in arr
-            li= item
-      
-      +list(['foo', 'bar', 'baz'])(id='myList', class='bold')
-  
-   yields:
-   
-       
              
-         
            • foo
              • 
-         
            • bar
              • 
-         
            • baz
              •

-mkdirp
-======
-
-Like `mkdir -p`, but in node.js!
-
-example
-=======
-
-pow.js
-------
-    var mkdirp = require('mkdirp');
-    
-    mkdirp('/tmp/foo/bar/baz', function (err) {
-        if (err) console.error(err)
-        else console.log('pow!')
-    });
-
-Output
-    pow!
-
-And now /tmp/foo/bar/baz exists, huzzah!
-
-methods
-=======
-
-var mkdirp = require('mkdirp');
-
-mkdirp(dir, mode, cb)
----------------------
-
-Create a new directory and any necessary subdirectories at `dir` with octal
-permission string `mode`.
-
-If `mode` isn't specified, it defaults to `0777 & (~process.umask())`.
-
-mkdirp.sync(dir, mode)
-----------------------
-
-Synchronously create a new directory and any necessary subdirectories at `dir`
-with octal permission string `mode`.
-
-If `mode` isn't specified, it defaults to `0777 & (~process.umask())`.
-
-install
-=======
-
-With [npm](http://npmjs.org) do:
-
-    npm install mkdirp
-
-license
-=======

-mkdirp
-======
-
-Like `mkdir -p`, but in node.js!
-
-[![build status](https://secure.travis-ci.org/substack/node-mkdirp.png)](http://travis-ci.org/substack/node-mkdirp)
-
-example
-=======
-
-pow.js
-------
-    var mkdirp = require('mkdirp');
-    
-    mkdirp('/tmp/foo/bar/baz', function (err) {
-        if (err) console.error(err)
-        else console.log('pow!')
-    });
-
-Output
-    pow!
-
-And now /tmp/foo/bar/baz exists, huzzah!
-
-methods
-=======
-
-var mkdirp = require('mkdirp');
-
-mkdirp(dir, mode, cb)
----------------------
-
-Create a new directory and any necessary subdirectories at `dir` with octal
-permission string `mode`.
-
-If `mode` isn't specified, it defaults to `0777 & (~process.umask())`.
-
-`cb(err, made)` fires with the error or the first directory `made`
-that had to be created, if any.
-
-mkdirp.sync(dir, mode)
-----------------------
-
-Synchronously create a new directory and any necessary subdirectories at `dir`
-with octal permission string `mode`.
-
-If `mode` isn't specified, it defaults to `0777 & (~process.umask())`.
-
-Returns the first directory that had to be created, if any.
-
-install
-=======
-
-With [npm](http://npmjs.org) do:
-
-    npm install mkdirp
-
-license
-=======

-- Node/Browser compatible. Published as `ms` in NPM.
-- If a number is supplied to `ms`, it returns it immediately.
-- If a string that contains the number is supplied, it returns it as
-a number (e.g: it returns `100` for `'100'`).
-- If you pass a string with a number and a valid unit, the number of
-equivalent ms is returned.

+This function is used to dynamically activate or deactivate a rule. The syntax for using this function is shown in below example.
+
+    RuleEngine.turn("OFF", {
+       "id": "one"
+    });
+
+Here `RuleEngine` is the rule engine instance. The first parameter to turn function indicates whether we need to turn the rule ON or OFF. The second parameter passed to the function is a filter. It should be a key which can be used to uniquely distinguish the targeted rule or set of rules from the other rules running in the Rule Engine. Here the above example will deactivate all the rules where the `id` attribute equals "one". 
+
+##### 2. `RuleEngine.prioritize(,)` 
+This function is used to dynamically change the priority of a rule while rule engine is running. It works similar to the Turn function and just that instead of the ON/OFF state we will be passing a priority number value to the function. See example below
+
+    RuleEngine.prioritize(10, {
+       "id": "one"
+    });
+
+The above `prioritize` call will give priority to Rule with id "one" over all the rules which are having lesser priority than 10.
+
+
+##### 3. `RuleEngine.register()`
+We know that we can pass Rules as parameter into the Rule Engine constructor while we create the Rule Engine object like below.
+
+    var RuleEngine = new RuleEngine(rules);
+
+Where `rules` can be either an array of rule objects or a single array. But what if we need to add some rules later to the Rule Engine. Register can be used any time to append new rules into the Rule Engine. It can be used like.
+
+    var RuleEngine = new RuleEngine();
+    RuleEngine.register(newrule);
+    RuleEngine.register(newrule);
+
+
+##### 4. `RuleEngine.findRules()`
+This function is used to retrieve the Rules which are registered on the Rule engine which matches the filter we pass as its parameter. A sample usage can be like below.
+
+    var rules = RuleEngine.findRules({"id": "one"});
+
+##### 5. `RuleEngine.init()`
+This function is used to remove all the rules registered on the Rule Engine. This is mostly used for rule clean up purposes by internal functions. A sample usage can be like below.
+
+    var RuleEngine = new RuleEngine();
+    RuleEngine.register(badrule);
+    RuleEngine.init();//removes the bad rule and cleans up
+    RuleEngine.register(newrule);

+This section deals with the case when you need to store the rules to an external Database or you need to load the rules stored inside an external Database.
+
+#### Export & Import Functions
+
+###### 1. toJSON()
+This function converts the Rules running inside the engine into JSON format. This is done by stringifying the condition and consequence functions internally. For details which you need to consider while using these features, please look into the "Gotchas" section below this.
+
+Find an example below
+
+    var rules = [{
+        "condition": function(R) {
+           R.when(1);
+        },
+        "consequence": function(R) {
+            R.stop();
+        },
+        "on": true
+    }];
+    var R1 = new RuleEngine(rules);
+    var store = R1.toJSON();
+
+###### 2. fromJSON()
+This function loads the stringified Rules back into the Rule engine. 
+
+:warning: **This uses eval() under the hood and should be considered dangerous!**
+
+Find an example below
+
+    var R1 = new RuleEngine();
+    R1.fromJSON(store);
+
+Where store variable is the one similar to what we get via a `toJSON()` call
+
+
+####Gotchas to consider before exporting or importing Rules
+
+###### 1. Dont directly JSON.stringify the rules array  
+
+As you can see the format of the rule we use in this engine is not exactly JSON. It is because of the fact that JSON wont allow functions to be values of keys in our Rule Object. So if we take rules array and do a `JSON.stringify`, we will just loose our functions as they will get removed in the process of stringification. So a fix for this might be to `stringify` and store the functions as strings while exporting them. This will require us to loop through each rule and do a `Function.toString()` call on both conditions and consequences. To do this you can use the `.toJSON()` function provided by this library which is explained in above section.
+
+###### 2. Dont use closures into rule objects.
+There are things that an eval cannot bring back once a JS object is stringified. One of which is the outer environment which was bound to it. So if your condition or consequence are using any variables which are outside its function level scope, then those bindings wont be  brought back when we load the stringified Rules back into the Rule engine from the store. If you dint understand this explanation or having troubles with this, you can raise an issue on the repo which we will help out.
+
+####Workaround for calling external methods from rules
+
+As a work around to allow for references to code in external modules in persisted rules here's a scheme where you can attach module references to the input fact being processed by the rules engine.
+
+First I establish 2 known fields on the input fact. The first called 'fact' contains the actual object we want to test/change inside the rules definitions. In the example below I'm getting the object as a POST to a service I've set up. The second is a field called modules which will contain references to modules containing code we may want to call from within our rules.
+
+    var inputObject = {};
+    inputObject.modules = {};
+    inputObject.fact = request.body;
+
+In order to populate the modules file I start with an array of field/module names like this:
+
+    var requiredModules = [{
+    	fieldName: "guidGenerator", 
+    	moduleName: 'uuid' 
+    },
+    {
+    	fieldName: 'sprintf',
+    	moduleName: 'sprintf'
+    }];
+
+I then populate the modules field in a loop like this:
+
+    for (var i = 0; i < rulesCollection.modules.length; i++) {
+        inputObject.modules[requiredModules[i].fieldName] = require(requiredModules[i].moduleName);
+    }
+
+I then refer to these fields in my rules. Here's an example rules consequence function:
+
+    function(R) {
+        this.fact.RecordId = this.modules.guidGenerator.v4();
+        this.fact.IPTCMetadata.Description = this.modules.sprintf.sprintf("%s Photo from user %s",
+            this.fact.IPTCMetadata.Description, this.fact.IncomingMetadata.User);
+        R.next();
+    }
+
+This seems to work fine and the main caveat is to make sure all the modules referenced in requiredModules are available.

+Facts are those input json values on which the rule engine applies its rule to obtain results. A fact can have multiple attributes as you decide.
+
+A sample Fact may look like
+
+    {
+	  "userIP": "27.3.4.5",
+	  "name":"user4",
+	  "application":"MOB2",
+	  "userLoggedIn":true,
+	  "transactionTotal":400,

+This is an object injected into the condition and consequence functions defined by the user to make it easy for the user to define the Rule Engine flow.
+
+If you look at the below rule example.
+
+    {
+		"name": "transaction minimum",
+		"priority": 3,
+		"on" : true,
+		"condition": function(R) {
+			R.when(this.transactionTotal < 500);
+		},
+		"consequence": function(R) {
+			this.result = false;
+			R.stop();
+		}
+    }
+
+The `R` object injected in both condition and consequence refers to the API we are talking about.
+
+
+Below are the functions available via the Flow Control API.
+
+#### R.when
+This function is used to pass the condition expression that we want to evaluate. In the above expression we pass the expression to check whether the transactionTotal attribute of the fact in context is below 500 or not. If the expression passed to `R.when` evaluates to true, then the condition will execute. Else the rule engine will move to next rule or may terminate if there are no rules left to apply.
+
+#### R.next
+This function is used inside consequence functions. This is used to instruct the rule engine to start applying the next rule on the fact if any.
+
+#### R.stop
+This function is used inside consequence functions to instruct the Rule Engine to stop processing the fact. If this function is called, even if rules are left to be applied, the rule engine will not apply rest of rules on the fact. It is used mostly when we arrive a conclusion on a particular fact and there is no need of any further process on it to generate a result. 
+
+As you can see above example, when the transaction is less than 500, we no longer need to process the rule. So stores false in result attribute and calls the stop immediately inside consequence.
+
+#### R.restart
+This function is used inside consequence functions to instruct the rule engine to begin applying the Rules on the fact from first. This function is also internally used by the Rule engine when the fact object is modified by a consequence function and it needs to go through all the rules once gain.

+Node-rules takes rules written in JSON friendly format as input. You can register different rules on the rule engine after initiating it. Once the rule engine is running with registered rules, you can feed it with different fact objects and the rule engine will process them with the various rules registered on it.

+A rule will consist of a condition and its corresponding consequence. If the fact you feed into the engine satisfies the condition, then the consequence will run. Also optionally user may choose to define the priority of a rule applied. The rule engine will be applying the rules on the fact according to the priority defined.
+
+Lets see how a sample rule will look like and then proceed to explain the different attributes of a rule.
+
+    {
+		"name": "transaction minimum",
+		"priority": 3,
+		"on" : true,
+		"condition": function(R) {
+			R.when(this.transactionTotal < 500);
+		},
+		"consequence": function(R) {
+			this.result = false;
+			R.stop();
+		}
+	}
+
+Above is a sample rule which has mandatory as well as optional parameters. You can choose to use which all attributes you need to use while defining your rule. Now lets look into the attributes one by one.
+
+###### 1. condition
+Condition is a function where the user can do the checks on the fact provided. The fact variable will be available in `this` context of the condition function. Lets see a sample condition below.
+
+	"condition": function(R) {
+		R.when(this.transactionTotal < 500);
+	}
+
+As you can see, the we have to pass an expression on to the `R.when` function which is a part of the [Flow Control API](https://github.com/mithunsatheesh/node-rules/wiki/Flow-Control-API). You can read more about the API [Flow Control API](https://github.com/mithunsatheesh/node-rules/wiki/Flow-Control-API). If the expression evaluates to true for a fact, the corresponding consequence will execute.
+
+Its mandatory to have this field.
+
+###### 2. consequence
+The consequence is the part where we define what happens when the condition evaluates to true for a particular fact. Just like in condition, fact variable will be available in `this` context. You may utilize it to add extra result attributes if needed.
+
+    "consequence": function(R) {
+		this.result = false;
+		R.stop();
+	}
+In the above example we use an additional parameter `result` to communicate to the code outside the rule engine that the fact has succeeded. Also the Rule API provides a number of functions here to control the flow of the rule engine. They are `R.stop()`, `R.restart()` and `R.next()`. Stop refers to stop processing the rule engine. Restart tells the rule engine to start applying all the rules again to the fact. Next is to instruct the rule engine to continue applying the rest of the rules to the fact before stopping. Check [Flow Control API](https://github.com/mithunsatheesh/node-rules/wiki/Flow-Control-API) in wiki to read more about this.
+
+You can read more about flow control API here.
+
+Its mandatory to have this field.
+
+###### 3. priority
+This field is used to specify the priority of a rule. The rules with higher priority will be applied on the fact first and then followed by lower priority rules. You can have multiple rules with same priority and the engine will not ensure the order in that case.
+
+Its not mandatory to have this field.
+
+###### 4. on
+This field is used to store the state of a rule. This is used to activate and deactivate rules at run time. Rules with `on` set to `false` will not be applied on the facts.
+
+It is not mandatory to have this field.
+
+###### 5. add a unique attribute
+It is suggested that you should add a property which can be used as a unique identifier for a rule. Why it is because when you need to dynamically turn on/off or change priority of a rule, you will need a filter to select a rule from the engine via the APIs. That time you may use the unique property as a key for the filter for selection process.
+
+Suppose that in the above example `name` is unique for each rule. Then for changing state or re prioritizing a rule at run time, you may use a filter like `{"name":"transaction minimum"}`. 
+
+Again its optional to add a unique identifier. You may ignore adding it to your rules if you are not changing rule states at run time.

+Anyone who is a core contributor (see the [Core Contributors Heading in the Readme](https://github.com/chaijs/chai#core-contributors)) can publish a release:
+
+1. Go to te [Releases page on Github](https://github.com/chaijs/chai/releases)
+2. Hit "Draft a new release" (if you can't see this, you're not a core contributor!)
+3. Write human-friendly Release Notes based on changelog.
+  - The release title is "x.x.x / YYYY-MM-DD" (where x.x.x is the version number)
+  - If breaking changes, write migration tutorial(s) and reasoning.
+  - Callouts for community contributions (PRs) with links to PR and contributing user.
+  - Callouts for other fixes made by core contributors with links to issue.
+4. Hit "Save Draft" and get other core contributors to check your work, or alternatively hit "Publish release"

+## What is Chai?
+
+Chai is an _assertion library_, similar to Node's build in `assert`. It makes testing much easier by giving you lots of assertions you can run against your code.
+
+## Installation
+
+### Node.js
+
+`chai` is available on [npm](http://npmjs.org). To install it, type:
+
+    $ npm install chai
+
+### Browsers
+
+You can also use it within the browser; install via npm and use the `chai.js` file found within the download. For example:
+
+```html
+
+```
+
+## Usage
+
+Import the library in your code, and then pick one of the styles you'd like to use - either `assert`, `expect` or `should`:
+
+```js
+var chai = require('chai');  
+var assert = chai.assert;    // Using Assert style
+var expect = chai.expect;    // Using Expect style
+var should = chai.should();  // Using Should style
+```
+
+### Pre-Native Modules Usage (_registers the chai testing style globally_)
+
+```js
+require('chai/register-assert');  // Using Assert style
+require('chai/register-expect');  // Using Expect style
+require('chai/register-should');  // Using Should style
+```
+
+### Pre-Native Modules Usage (_as local variables_)
+
+```js
+const { assert } = require('chai');  // Using Assert style
+const { expect } = require('chai');  // Using Expect style
+const { should } = require('chai');  // Using Should style
+should();  // Modifies `Object.prototype`
 
-[![Selenium Test Status](https://saucelabs.com/browser-matrix/chaijs.svg)](https://saucelabs.com/u/chaijs)
+const { expect, use } = require('chai');  // Creates local variables `expect` and `use`; useful for plugin use
+```
 
-### Plugins
+### Native Modules Usage (_registers the chai testing style globally_)
+
+```js
+import 'chai/register-assert';  // Using Assert style
+import 'chai/register-expect';  // Using Expect style
+import 'chai/register-should';  // Using Should style
+```
+
+### Native Modules Usage (_local import only_)
+
+```js
+import { assert } from 'chai';  // Using Assert style
+import { expect } from 'chai';  // Using Expect style
+import { should } from 'chai';  // Using Should style
+should();  // Modifies `Object.prototype`
+```
+
+### Usage with Mocha
+
+```bash
+mocha spec.js -r chai/register-assert  # Using Assert style
+mocha spec.js -r chai/register-expect  # Using Expect style
+mocha spec.js -r chai/register-should  # Using Should style
+```
+
+[Read more about these styles in our docs](http://chaijs.com/guide/styles/).
+

+expect('test').to.have.ownPropertyDescriptor('length', { enumerable: false, configurable: false, writable: false, value: 4 });
+expect('test').not.to.have.ownPropertyDescriptor('length', { enumerable: false, configurable: false, writable: false, value: 3 });
+expect('test').ownPropertyDescriptor('length').to.have.property('enumerable', false);
+expect('test').ownPropertyDescriptor('length').to.have.keys('value');
+```

+   *   fails.
+   *
+   * - `ssfi`: This flag stands for "start stack function indicator". It
+   *   contains a function reference that serves as the starting point for
+   *   removing frames from the stack trace of the error that's created by the
+   *   assertion when it fails. The goal is to provide a cleaner stack trace to
+   *   end users by removing Chai's internal functions. Note that it only works
+   *   in environments that support `Error.captureStackTrace`, and only when
+   *   `Chai.config.includeStack` hasn't been set to `false`.
+   *
+   * - `lockSsfi`: This flag controls whether or not the given `ssfi` flag
+   *   should retain its current value, even as assertions are chained off of
+   *   this object. This is usually set to `true` when creating a new assertion
+   *   from within another assertion. It's also temporarily set to `true` before

+   *
+   *     expect(goodFn).to.not.throw();
+   * 
+   * However, it's dangerous to negate `.throw` when providing any arguments.
+   * The problem is that it creates uncertain expectations by asserting that the
+   * target either doesn't throw an error, or that it throws an error but of a
+   * different type than the given type, or that it throws an error of the given
+   * type but with a message that doesn't include the given string. It's often
+   * best to identify the exact output that's expected, and then write an
+   * assertion that only accepts that exact output.
+   *
+   * When the target isn't expected to throw an error, it's often best to assert
+   * exactly that.
+   *
+   *     var goodFn = function () {};
+   *
+   *     expect(goodFn).to.not.throw(); // Recommended
+   *     expect(goodFn).to.not.throw(ReferenceError, 'x'); // Not recommended
+   *
+   * When the target is expected to throw an error, it's often best to assert
+   * that the error is of its expected type, and has a message that includes an
+   * expected string, rather than asserting that it doesn't have one of many
+   * unexpected types, and doesn't have a message that includes some string.
+   *
+   *     var badFn = function () { throw new TypeError('Illegal salmon!'); };
+   *
+   *     expect(badFn).to.throw(TypeError, 'salmon'); // Recommended
+   *     expect(badFn).to.not.throw(ReferenceError, 'x'); // Not recommended
+   *
+   * `.throw` changes the target of any assertions that follow in the chain to
+   * be the error object that's thrown.
+   *
+   *     var err = new TypeError('Illegal salmon!');
+   *     err.code = 42;
+   *     var badFn = function () { throw err; };
+   *
+   *     expect(badFn).to.throw(TypeError).with.property('code', 42);
+   *
+   * `.throw` accepts an optional `msg` argument which is a custom error message
+   * to show when the assertion fails. The message can also be given as the
+   * second argument to `expect`. When not providing two arguments, always use
+   * the second form.
+   *
+   *     var goodFn = function () {};
+   *
+   *     expect(goodFn).to.throw(TypeError, 'x', 'nooo why fail??');
+   *     expect(goodFn, 'nooo why fail??').to.throw();
+   *
+   * Due to limitations in ES5, `.throw` may not always work as expected when
+   * using a transpiler such as Babel or TypeScript. In particular, it may
+   * produce unexpected results when subclassing the built-in `Error` object and
+   * then passing the subclassed constructor to `.throw`. See your transpiler's
+   * docs for details:
+   *
+   * - ([Babel](https://babeljs.io/docs/usage/caveats/#classes))
+   * - ([TypeScript](https://github.com/Microsoft/TypeScript/wiki/Breaking-Changes#extending-built-ins-like-error-array-and-map-may-no-longer-work))
+   *
+   * Beware of some common mistakes when using the `throw` assertion. One common
+   * mistake is to accidentally invoke the function yourself instead of letting
+   * the `throw` assertion invoke the function for you. For example, when
+   * testing if a function named `fn` throws, provide `fn` instead of `fn()` as
+   * the target for the assertion.
+   *
+   *     expect(fn).to.throw();     // Good! Tests `fn` as desired
+   *     expect(fn()).to.throw();   // Bad! Tests result of `fn()`, not `fn`
+   *
+   * If you need to assert that your function `fn` throws when passed certain
+   * arguments, then wrap a call to `fn` inside of another function.
+   *
+   *     expect(function () { fn(42); }).to.throw();  // Function expression
+   *     expect(() => fn(42)).to.throw();             // ES6 arrow function
+   *
+   * Another common mistake is to provide an object method (or any stand-alone
+   * function that relies on `this`) as the target of the assertion. Doing so is
+   * problematic because the `this` context will be lost when the function is
+   * invoked by `.throw`; there's no way for it to know what `this` is supposed
+   * to be. There are two ways around this problem. One solution is to wrap the
+   * method or function call inside of another function. Another solution is to
+   * use `bind`.
+   *
+   *     expect(function () { cat.meow(); }).to.throw();  // Function expression
+   *     expect(() => cat.meow()).to.throw();             // ES6 arrow function
+   *     expect(cat.meow.bind(cat)).to.throw();           // Bind
+   *
+   * Finally, it's worth mentioning that it's a best practice in JavaScript to
+   * only throw `Error` and derivatives of `Error` such as `ReferenceError`,
+   * `TypeError`, and user-defined objects that extend `Error`. No other type of
+   * value will generate a stack trace when initialized. With that said, the
+   * `throw` assertion does technically support any type of value being thrown,
+   * not just `Error` and its derivatives.
+   *
+   * The aliases `.throws` and `.Throw` can be used interchangeably with
+   * `.throw`.

+ * without modification.

+ * Note that in ES6, the function's `length` property is configurable, so once

+   *   fails.
+   *
+   * - `ssfi`: This flag stands for "start stack function indicator". It
+   *   contains a function reference that serves as the starting point for

+   *   assertion when it fails. The goal is to provide a cleaner stack trace to

+   *   in environments that support `Error.captureStackTrace`, and only when
+   *   `Chai.config.includeStack` hasn't been set to `false`.
+   *
+   * - `lockSsfi`: This flag controls whether or not the given `ssfi` flag
+   *   should retain its current value, even as assertions are chained off of
+   *   this object. This is usually set to `true` when creating a new assertion

+   *
+   * When the target is a string, `.include` asserts that the given string `val`
+   * is a substring of the target.
+   *
+   *     expect('foobar').to.include('foo');
+   *
+   * When the target is an array, `.include` asserts that the given `val` is a
+   * member of the target.
+   *
+   *     expect([1, 2, 3]).to.include(2);
+   *
+   * When the target is an object, `.include` asserts that the given object
+   * `val`'s properties are a subset of the target's properties.
+   *
+   *     expect({a: 1, b: 2, c: 3}).to.include({a: 1, b: 2});
+   *
+   * When the target is a Set or WeakSet, `.include` asserts that the given `val` is a
+   * member of the target. SameValueZero equality algorithm is used.
+   *
+   *     expect(new Set([1, 2])).to.include(2);
+   *
+   * When the target is a Map, `.include` asserts that the given `val` is one of
+   * the values of the target. SameValueZero equality algorithm is used.
+   *
+   *     expect(new Map([['a', 1], ['b', 2]])).to.include(2);
+   *
+   * Because `.include` does different things based on the target's type, it's
+   * important to check the target's type before using `.include`. See the `.a`
+   * doc for info on testing a target's type.
+   *
+   *     expect([1, 2, 3]).to.be.an('array').that.includes(2);
+   *
+   * By default, strict (`===`) equality is used to compare array members and
+   * object properties. Add `.deep` earlier in the chain to use deep equality
+   * instead (WeakSet targets are not supported). See the `deep-eql` project
+   * page for info on the deep equality algorithm: https://github.com/chaijs/deep-eql.
+   *
+   *     // Target array deeply (but not strictly) includes `{a: 1}`
+   *     expect([{a: 1}]).to.deep.include({a: 1});
+   *     expect([{a: 1}]).to.not.include({a: 1});
+   *
+   *     // Target object deeply (but not strictly) includes `x: {a: 1}`
+   *     expect({x: {a: 1}}).to.deep.include({x: {a: 1}});
+   *     expect({x: {a: 1}}).to.not.include({x: {a: 1}});
+   *
+   * By default, all of the target's properties are searched when working with
+   * objects. This includes properties that are inherited and/or non-enumerable.
+   * Add `.own` earlier in the chain to exclude the target's inherited
+   * properties from the search.
+   *
+   *     Object.prototype.b = 2;
+   *
+   *     expect({a: 1}).to.own.include({a: 1});
+   *     expect({a: 1}).to.include({b: 2}).but.not.own.include({b: 2});
+   *
+   * Note that a target object is always only searched for `val`'s own
+   * enumerable properties.
    *
-   * The `include` and `contain` assertions can be used as either property
-   * based language chains or as methods to assert the inclusion of an object
-   * in an array or a substring in a string. When used as language chains,
-   * they toggle the `contain` flag for the `keys` assertion.
+   * `.deep` and `.own` can be combined.
    *
-   *     expect([1,2,3]).to.include(2);
-   *     expect('foobar').to.contain('foo');
-   *     expect({ foo: 'bar', hello: 'universe' }).to.include.keys('foo');
+   *     expect({a: {b: 2}}).to.deep.own.include({a: {b: 2}});
+   *
+   * Add `.nested` earlier in the chain to enable dot- and bracket-notation when
+   * referencing nested properties.
+   *
+   *     expect({a: {b: ['x', 'y']}}).to.nested.include({'a.b[1]': 'y'});
+   *
+   * If `.` or `[]` are part of an actual property name, they can be escaped by
+   * adding two backslashes before them.
+   *
+   *     expect({'.a': {'[b]': 2}}).to.nested.include({'\\.a.\\[b\\]': 2});
+   *
+   * `.deep` and `.nested` can be combined.
+   *
+   *     expect({a: {b: [{c: 3}]}}).to.deep.nested.include({'a.b[0]': {c: 3}});
+   *
+   * `.own` and `.nested` cannot be combined.
+   *
+   * Add `.not` earlier in the chain to negate `.include`.
+   *
+   *     expect('foobar').to.not.include('taco');
+   *     expect([1, 2, 3]).to.not.include(4);
+   * 
+   * However, it's dangerous to negate `.include` when the target is an object.
+   * The problem is that it creates uncertain expectations by asserting that the
+   * target object doesn't have all of `val`'s key/value pairs but may or may
+   * not have some of them. It's often best to identify the exact output that's
+   * expected, and then write an assertion that only accepts that exact output.
+   *
+   * When the target object isn't even expected to have `val`'s keys, it's
+   * often best to assert exactly that.
+   *
+   *     expect({c: 3}).to.not.have.any.keys('a', 'b'); // Recommended
+   *     expect({c: 3}).to.not.include({a: 1, b: 2}); // Not recommended
+   *
+   * When the target object is expected to have `val`'s keys, it's often best to
+   * assert that each of the properties has its expected value, rather than
+   * asserting that each property doesn't have one of many unexpected values.
+   *
+   *     expect({a: 3, b: 4}).to.include({a: 3, b: 4}); // Recommended
+   *     expect({a: 3, b: 4}).to.not.include({a: 1, b: 2}); // Not recommended
+   *
+   * `.include` accepts an optional `msg` argument which is a custom error
+   * message to show when the assertion fails. The message can also be given as
+   * the second argument to `expect`.
+   *
+   *     expect([1, 2, 3]).to.include(4, 'nooo why fail??');
+   *     expect([1, 2, 3], 'nooo why fail??').to.include(4);
+   *
+   * `.include` can also be used as a language chain, causing all `.members` and
+   * `.keys` assertions that follow in the chain to require the target to be a
+   * superset of the expected set, rather than an identical set. Note that
+   * `.members` ignores duplicates in the subset when `.include` is added.
+   *
+   *     // Target object's keys are a superset of ['a', 'b'] but not identical
+   *     expect({a: 1, b: 2, c: 3}).to.include.all.keys('a', 'b');
+   *     expect({a: 1, b: 2, c: 3}).to.not.have.all.keys('a', 'b');
+   *
+   *     // Target array is a superset of [1, 2] but not identical
+   *     expect([1, 2, 3]).to.include.members([1, 2]);
+   *     expect([1, 2, 3]).to.not.have.members([1, 2]);
+   *
+   *     // Duplicates in the subset are ignored
+   *     expect([1, 2, 3]).to.include.members([1, 2, 2, 2]);
+   *
+   * Note that adding `.any` earlier in the chain causes the `.keys` assertion
+   * to ignore `.include`.
+   *
+   *     // Both assertions are identical
+   *     expect({a: 1}).to.include.any.keys('a', 'b');

+   * The problem is that it creates uncertain expectations by asserting that the

+   * When the target is expected to throw an error, it's often best to assert
+   * that the error is of its expected type, and has a message that includes an
+   * expected string, rather than asserting that it doesn't have one of many
+   * unexpected types, and doesn't have a message that includes some string.
+   *
+   *     var badFn = function () { throw new TypeError('Illegal salmon!'); };
+   *
+   *     expect(badFn).to.throw(TypeError, 'salmon'); // Recommended
+   *     expect(badFn).to.not.throw(ReferenceError, 'x'); // Not recommended
+   *
+   * `.throw` changes the target of any assertions that follow in the chain to
+   * be the error object that's thrown.
+   *
+   *     var err = new TypeError('Illegal salmon!');
+   *     err.code = 42;

+   *
+   *     expect(badFn).to.throw(TypeError).with.property('code', 42);
+   *
+   * `.throw` accepts an optional `msg` argument which is a custom error message
+   * to show when the assertion fails. The message can also be given as the
+   * second argument to `expect`. When not providing two arguments, always use
+   * the second form.
+   *
+   *     var goodFn = function () {};
+   *
+   *     expect(goodFn).to.throw(TypeError, 'x', 'nooo why fail??');
+   *     expect(goodFn, 'nooo why fail??').to.throw();
+   *
+   * Due to limitations in ES5, `.throw` may not always work as expected when
+   * using a transpiler such as Babel or TypeScript. In particular, it may
+   * produce unexpected results when subclassing the built-in `Error` object and
+   * then passing the subclassed constructor to `.throw`. See your transpiler's
+   * docs for details:
+   *
+   * - ([Babel](https://babeljs.io/docs/usage/caveats/#classes))
+   * - ([TypeScript](https://github.com/Microsoft/TypeScript/wiki/Breaking-Changes#extending-built-ins-like-error-array-and-map-may-no-longer-work))
+   *
+   * Beware of some common mistakes when using the `throw` assertion. One common
+   * mistake is to accidentally invoke the function yourself instead of letting
+   * the `throw` assertion invoke the function for you. For example, when
+   * testing if a function named `fn` throws, provide `fn` instead of `fn()` as
+   * the target for the assertion.
+   *
+   *     expect(fn).to.throw();     // Good! Tests `fn` as desired
+   *     expect(fn()).to.throw();   // Bad! Tests result of `fn()`, not `fn`
+   *
+   * If you need to assert that your function `fn` throws when passed certain
+   * arguments, then wrap a call to `fn` inside of another function.
+   *
+   *     expect(function () { fn(42); }).to.throw();  // Function expression
+   *     expect(() => fn(42)).to.throw();             // ES6 arrow function
+   *
+   * Another common mistake is to provide an object method (or any stand-alone
+   * function that relies on `this`) as the target of the assertion. Doing so is
+   * problematic because the `this` context will be lost when the function is
+   * invoked by `.throw`; there's no way for it to know what `this` is supposed
+   * to be. There are two ways around this problem. One solution is to wrap the
+   * method or function call inside of another function. Another solution is to
+   * use `bind`.
+   *
+   *     expect(function () { cat.meow(); }).to.throw();  // Function expression
+   *     expect(() => cat.meow()).to.throw();             // ES6 arrow function
+   *     expect(cat.meow.bind(cat)).to.throw();           // Bind
+   *
+   * Finally, it's worth mentioning that it's a best practice in JavaScript to
+   * only throw `Error` and derivatives of `Error` such as `ReferenceError`,
+   * `TypeError`, and user-defined objects that extend `Error`. No other type of
+   * value will generate a stack trace when initialized. With that said, the
+   * `throw` assertion does technically support any type of value being thrown,
+   * not just `Error` and its derivatives.
+   *
+   * The aliases `.throws` and `.Throw` can be used interchangeably with
+   * `.throw`.

-### Rules
-
-- Strict equality for non-traversable nodes according to [egal](http://wiki.ecmascript.org/doku.php?id=harmony:egal).
-  - `eql(NaN, NaN).should.be.true;`
-  - `eql(-0, +0).should.be.false;`

-### Library
-
-A `Library` is a small constructed repository for custom type detections.
-
-```js
-var lib = new type.Library;
-```
-
-#### .of (obj)
-
-* **@param** _{Mixed}_ object to test
-* **@return** _{String}_  type
-
-Expose replacement `typeof` detection to the library.
-
-```js
-if ('string' === lib.of('hello world')) {
-  // ...
-}
-```
-
-
-#### .define (type, test)
-
-* **@param** _{String}_ type 
-* **@param** _{RegExp|Function}_ test 
-
-Add a test to for the `.test()` assertion.
-
-Can be defined as a regular expression:
-
-```js
-lib.define('int', /^[0-9]+$/);
-```
-
-... or as a function:
-
-```js
-lib.define('bln', function (obj) {
-  if ('boolean' === lib.of(obj)) return true;
-  var blns = [ 'yes', 'no', 'true', 'false', 1, 0 ];
-  if ('string' === lib.of(obj)) obj = obj.toLowerCase();
-  return !! ~blns.indexOf(obj);
-});
-```
-
-
-#### .test (obj, test)
-
-* **@param** _{Mixed}_ object 
-* **@param** _{String}_ type 
-* **@return** _{Boolean}_  result
-
-Assert that an object is of type. Will first
-check natives, and if that does not pass it will
-use the user defined custom tests.
-
-```js
-assert(lib.test('1', 'int'));
-assert(lib.test('yes', 'bln'));
-```

-# Chai Contribution Guidelines
-
-We like to encourage you to contribute to the Chai.js repository. This should be as easy as possible for you but there are a few things to consider when contributing. The following guidelines for contribution should be followed if you want to submit a pull request or open an issue.
-
-Following these guidelines helps to communicate that you respect the time of the developers managing and developing this open source project. In return, they should reciprocate that respect in addressing your issue or assessing patches and features.
-

-- [Contributing](#contributing)
-  - [Bug Reports](#bugs)

-
-## TLDR;
-
-- Creating an Issue or Pull Request requires a [GitHub](http://github.com) account.
-- Issue reports should be **clear**, **concise** and **reproducible**. Check to see if your issue has already been resolved in the [master]() branch or already reported in Chai's [GitHub Issue Tracker](https://github.com/chaijs/chai/issues).
-- Pull Requests must adhere to strict [coding style guidelines](https://github.com/chaijs/chai/wiki/Chai-Coding-Style-Guide).
-- In general, avoid submitting PRs for new Assertions without asking core contributors first. More than likely it would be better implemented as a plugin.
-- Additional support is available via the [Google Group](http://groups.google.com/group/chaijs) or on irc.freenode.net#chaijs.
-- **IMPORTANT**: By submitting a patch, you agree to allow the project owner to license your work under the same license as that used by the project.

-
-
-## Contributing
-
-The issue tracker is the preferred channel for [bug reports](#bugs),
-[feature requests](#features) and [submitting pull
-requests](#pull-requests), but please respect the following restrictions:
-
-* Please **do not** use the issue tracker for personal support requests (use
-  [Google Group](https://groups.google.com/forum/#!forum/chaijs) or IRC).
-* Please **do not** derail or troll issues. Keep the discussion on topic and
-  respect the opinions of others
-
-
-### Bug Reports
-
-A bug is a **demonstrable problem** that is caused by the code in the repository.
-
-Guidelines for bug reports:
-
-1. **Use the GitHub issue search** — check if the issue has already been reported.
-2. **Check if the issue has been fixed** — try to reproduce it using the latest `master` or development branch in the repository.
-3. **Isolate the problem** — create a test case to demonstrate your issue. Provide either a repo, gist, or code sample to demonstrate you problem.
-
-A good bug report shouldn't leave others needing to chase you up for more information. Please try to be as detailed as possible in your report. What is your environment? What steps will reproduce the issue? What browser(s) and/or Node.js versions experience the problem? What would you expect to be the outcome? All these details will help people to fix any potential bugs.
-
-Example:
-
-> Short and descriptive example bug report title
->
-> A summary of the issue and the browser/OS environment in which it occurs. If suitable, include the steps required to reproduce the bug.
->
-> 1. This is the first step
-> 2. This is the second step
-> 3. Further steps, etc.
->
-> `` - a link to the reduced test case OR
-> ```js
-> expect(a).to.equal('a');
-> // code sample
-> ```
->
-> Any other information you want to share that is relevant to the issue being reported. This might include the lines of code that you have identified as causing the bug, and potential solutions (and your opinions on their merits).
-
-
-### Feature Requests
-
-Feature requests are welcome. But take a moment to find out whether your idea fits with the scope and aims of the project. It's up to *you* to make a strong case to convince the project's developers of the merits of this feature. Please provide as much detail and context as possible.
-
-Furthermore, since Chai.js has a [robust plugin API](http://chaijs.com/guide/plugins/), we encourage you to publish **new Assertions** as plugins. If your feature is an enhancement to an **existing Assertion**, please propose your changes as an issue prior to opening a pull request. If the core Chai.js contributors feel your plugin would be better suited as a core assertion, they will invite you to open a PR in [chaijs/chai](https://github.com/chaijs/chai).
-
-
-### Pull Requests
-
-- PRs for new core-assertions are advised against.
-- PRs for core-assertion bug fixes are always welcome.
-- PRs for enhancing the interfaces are always welcome.
-- PRs that increase test coverage are always welcome.
-- PRs are scrutinized for coding-style.
-
-Good pull requests - patches, improvements, new features - are a fantastic help. They should remain focused in scope and avoid containing unrelated commits.
-
-**Please ask first** before embarking on any significant pull request (e.g. implementing features, refactoring code), otherwise you risk spending a lot of time working on something that the project's developers might not want to merge into the project.
-
-Please adhere to the coding conventions used throughout a project (indentation, accurate comments, etc.) and any other requirements (such as test coverage). Please review the [Chai.js Coding Style Guide](https://github.com/chaijs/chai/wiki/Chai-Coding-Style-Guide).
-
-Follow this process if you'd like your work considered for inclusion in the project:
-
-1. [Fork](http://help.github.com/fork-a-repo/) the project, clone your fork, and configure the remotes:
-
-```bash
-# Clone your fork of the repo into the current directory
-git clone https://github.com//
-# Navigate to the newly cloned directory
-cd 
-# Assign the original repo to a remote called "upstream"
-git remote add upstream https://github.com//
-```
-
-2. If you cloned a while ago, get the latest changes from upstream:
-
-```bash
-git checkout 
-git pull upstream 
-```
-
-3. Create a new topic branch (off the main project development branch) to contain your feature, change, or fix:
-
-```bash
-git checkout -b 
-```
-
-4. Commit your changes in logical chunks. Use Git's [interactive rebase](https://help.github.com/articles/interactive-rebase) feature to tidy up your commits before making them public.
-
-5. Run you code to make sure it works. If you're still having problems please try to run `make clean` and then test your code again.
-
-```bash
-npm test
-# when finished running tests...
-git checkout chai.js
-```
-
-6. Locally merge (or rebase) the upstream development branch into your topic branch:
-
-```bash
-git pull [--rebase] upstream 
-```
-
-7. Push your topic branch up to your fork:
-
-```bash
-git push origin 
-```
-
-8. [Open a Pull Request](https://help.github.com/articles/using-pull-requests/) with a clear title and description.
-
-**IMPORTANT**: By submitting a patch, you agree to allow the project owner to license your work under the same license as that used by the project.
-
-
-## Releasing
-
-Releases can be **prepared** by anyone with access to the code.
-
-Simply run `make release-major`, `make release-minor`, or `make-release-patch`
-and it will automatically do the following:
-
- - Build chai.js
- - Bump the version numbers accross the project
- - Make a commit within git
-
-All you need to do is push the commit up and make a pull request, one of the core contributors will merge it and publish a release.
-
-### Publishing a Release
-
-Anyone who is a core contributor (see the [Core Contributors Heading in the Readme](https://github.com/chaijs/chai#core-contributors)) can publish a release:
-
-1. Go to te [Releases page on Github](https://github.com/chaijs/chai/releases)
-2. Hit "Draft a new release" (if you can't see this, you're not a core contributor!)
-3. Write human-friendly Release Notes based on changelog.
-  - The release title is "x.x.x / YYYY-MM-DD" (where x.x.x is the version number)
-  - If breaking changes, write migration tutorial(s) and reasoning.
-  - Callouts for community contributions (PRs) with links to PR and contributing user.
-  - Callouts for other fixes made by core contributors with links to issue.
-4. Hit "Save Draft" and get other core contributors to check your work, or alternatively hit "Publish release"
-5. That's it!

-## What is Chai?
-
-Chai is an _assertion library_, similar to Node's build in `assert`. It makes testing much easier by giving you lots of assertions you can run against your code.
-
-## Installation
-
-### Node.js
-
-`chai` is available on [npm](http://npmjs.org). To install it, type:
-
-    $ npm install chai
-
-### Browsers
-
-You can also use it within the browser; install via npm and use the `chai.js` file found within the download. For example:
-
-```html
-
-```
-
-## Usage
-
-Import the library in your code, and then pick one of the styles you'd like to use - either `assert`, `expect` or `should`:
-
-```js
-var chai = require('chai');  
-var assert = chai.assert;    // Using Assert style
-var expect = chai.expect;    // Using Expect style
-var should = chai.should();  // Using Should style
-```
-
-### Pre-Native Modules Usage (_registers the chai testing style globally_)
-
-```js
-require('chai/register-assert');  // Using Assert style
-require('chai/register-expect');  // Using Expect style
-require('chai/register-should');  // Using Should style
-```
-
-### Pre-Native Modules Usage (_as local variables_)
-
-```js
-const { assert } = require('chai');  // Using Assert style
-const { expect } = require('chai');  // Using Expect style
-const { should } = require('chai');  // Using Should style
-should();  // Modifies `Object.prototype`
-
-const { expect, use } = require('chai');  // Creates local variables `expect` and `use`; useful for plugin use
-```
-
-### Native Modules Usage (_registers the chai testing style globally_)
-
-```js
-import 'chai/register-assert';  // Using Assert style
-import 'chai/register-expect';  // Using Expect style
-import 'chai/register-should';  // Using Should style
-```
-
-### Native Modules Usage (_local import only_)
-
-```js
-import { assert } from 'chai';  // Using Assert style
-import { expect } from 'chai';  // Using Expect style
-import { should } from 'chai';  // Using Should style
-should();  // Modifies `Object.prototype`
-```
-
-### Usage with Mocha
-
-```bash
-mocha spec.js -r chai/register-assert  # Using Assert style
-mocha spec.js -r chai/register-expect  # Using Expect style
-mocha spec.js -r chai/register-should  # Using Should style
-```
-
-[Read more about these styles in our docs](http://chaijs.com/guide/styles/).
-
-## Plugins
-
-Chai offers a robust Plugin architecture for extending Chai's assertions and interfaces.
-
-- Need a plugin? View the [official plugin list](http://chaijs.com/plugins).
-- Want to build a plugin? Read the [plugin api documentation](http://chaijs.com/guide/plugins/).
-- Have a plugin and want it listed? Simply add the following keywords to your package.json:
-  -  `chai-plugin`
-  -  `browser` if your plugin works in the browser as well as Node.js
-  -  `browser-only` if your plugin does not work with Node.js

-## 1.10.0 / 2014-11-10
-
-The following changes are required if you are upgrading from the previous version:
-
-- **Users:**
-  - No changes required
-- **Plugin Developers:**
-  - Review `addChainableNoop` notes below.
-- **Core Contributors:**
-  - Refresh `node_modules` folder for updated dependencies.
-
-### Noop Function for Terminating Assertion Properties
-
-The following assertions can now also be used in the function-call form:
-
-* ok
-* true
-* false
-* null
-* undefined
-* exist
-* empty
-* arguments
-* Arguments
-
-The above list of assertions are property getters that assert immediately on
-access. Because of that, they were written to be used by terminating the assertion
-chain with a property access.
-
-```js
-expect(true).to.be.true;
-foo.should.be.ok;
-```
-
-This syntax is definitely aesthetically pleasing but, if you are linting your
-test code, your linter will complain with an error something like "Expected an
-assignment or function call and instead saw an expression." Since the linter
-doesn't know about the property getter it assumes this line has no side-effects,
-and throws a warning in case you made a mistake.
-
-Squelching these errors is not a good solution as test code is getting to be
-just as important as, if not more than, production code. Catching syntactical
-errors in tests using static analysis is a great tool to help make sure that your
-tests are well-defined and free of typos.
-
-A better option was to provide a function-call form for these assertions so that
-the code's intent is more clear and the linters stop complaining about something
-looking off. This form is added in addition to the existing property access form
-and does not impact existing test code.
-
-```js
-expect(true).to.be.true();
-foo.should.be.ok();
-```
-
-These forms can also be mixed in any way, these are all functionally identical:
-
-```js
-expect(true).to.be.true.and.not.false();
-expect(true).to.be.true().and.not.false;
-expect(true).to.be.true.and.not.false;
-```
-
-#### Plugin Authors
-
-If you would like to provide this function-call form for your terminating assertion
-properties, there is a new function to register these types of asserts. Instead
-of using `addProperty` to register terminating assertions, simply use `addChainableNoop`
-instead; the arguments to both are identical. The latter will make the assertion
-available in both the attribute and function-call forms and should have no impact
-on existing users of your plugin.

-## 1.9.1 / 2014-03-19
-
-The following changes are required if you are upgrading from the previous version:
-
-- **Users:**
-  - Migrate configuration options to new interface. (see notes)
-- **Plugin Developers:**
-  - No changes required
-- **Core Contributors:**
-  - Refresh `node_modules` folder for updated dependencies.
-
-### Configuration
-
-There have been requests for changes and additions to the configuration mechanisms
-and their impact in the Chai architecture. As such, we have decoupled the
-configuration from the `Assertion` constructor. This not only allows for centralized
-configuration, but will allow us to shift the responsibility from the `Assertion`
-constructor to the `assert` interface in future releases.
-
-These changes have been implemented in a non-breaking way, but a depretiation
-warning will be presented to users until they migrate. The old config method will
-be removed in either `v1.11.0` or `v2.0.0`, whichever comes first.
-
-#### Quick Migration
-
-```js
-// change this:
-chai.Assertion.includeStack = true;
-chai.Assertion.showDiff = false;
-
-// ... to this:
-chai.config.includeStack = true;
-chai.config.showDiff = false;
-```
-
-#### All Config Options
-
-##### config.includeStack
-
-- **@param** _{Boolean}_
-- **@default** `false`
-
-User configurable property, influences whether stack trace is included in
-Assertion error message. Default of `false` suppresses stack trace in the error
-message.
-
-##### config.showDiff
-
-- **@param** _{Boolean}_
-- **@default** `true`
-
-User configurable property, influences whether or not the `showDiff` flag
-should be included in the thrown AssertionErrors. `false` will always be `false`;
-`true` will be true when the assertion has requested a diff be shown.
-
-##### config.truncateThreshold **(NEW)**
-
-- **@param** _{Number}_
-- **@default** `40`
-
-User configurable property, sets length threshold for actual and expected values
-in assertion errors. If this threshold is exceeded, the value is truncated.
-
-Set it to zero if you want to disable truncating altogether.
-
-```js
-chai.config.truncateThreshold = 0; // disable truncating
-```

-
-The following changes are required if you are upgrading from the previous version:
-
-- **Users:**
-  - See `deep.equal` notes.
-- **Plugin Developers:**
-  - No changes required
-- **Core Contributors:**
-  - Refresh `node_modules` folder for updated dependencies.
-
-### Deep Equals
-
-This version of Chai focused on a overhaul to the deep equal utility. The code for this
-tool has been removed from the core lib and can now be found at:
-[chai / deep-eql](https://github.com/chaijs/deep-eql). As stated in previous releases,
-this is part of a larger initiative to provide transparency, independent testing, and coverage for
-some of the more complicated internal tools.
-
-For the most part `.deep.equal` will behave the same as it has. However, in order to provide a
-consistent ruleset across all types being tested, the following changes have been made and _might_
-require changes to your tests.
-
-**1.** Strict equality for non-traversable nodes according to [egal](http://wiki.ecmascript.org/doku.php?id=harmony:egal).
-
-_Previously:_ Non-traversable equal via `===`.
-
-```js
-expect(NaN).to.deep.equal(NaN);
-expect(-0).to.not.deep.equal(+0);
-```
-
-**2.** Arguments are not Arrays (and all types must be equal):
-
-_Previously:_ Some crazy nonsense that led to empty arrays deep equaling empty objects deep equaling dates.
-
-```js
-expect(arguments).to.not.deep.equal([]);
-expect(Array.prototype.slice.call(arguments)).to.deep.equal([]);
-```
-
-- [#156](https://github.com/chaijs/chai/issues/156) Empty object is eql to empty array
-- [#192](https://github.com/chaijs/chai/issues/192) empty object is eql to a Date object
-- [#194](https://github.com/chaijs/chai/issues/194) refactor deep-equal utility
-
-### CI and Browser Testing
-
-Chai now runs the browser CI suite using [Karma](http://karma-runner.github.io/) directed at
-[SauceLabs](https://saucelabs.com/). This means we get to know where our browser support stands...
-and we get a cool badge:
-
-[![Selenium Test Status](https://saucelabs.com/browser-matrix/logicalparadox.svg)](https://saucelabs.com/u/logicalparadox)
-
-Look for the list of browsers/versions to expand over the coming releases.

-### Coverage Reporting
-
-Coverage reporting has always been available for core-developers but the data has never been published
-for our end users. In our ongoing effort to improve accountability this data will now be published via
-the [coveralls.io](https://coveralls.io/) service. A badge has been added to the README and the full report
-can be viewed online at the [chai coveralls project](https://coveralls.io/r/chaijs/chai). Furthermore, PRs
-will receive automated messages indicating how their PR impacts test coverage. This service is tied to TravisCI.

-

-  - No changes required.
-- **Plugin Developers:**
-  - Review AssertionError update notice.
-- **Core Contributors:**
-  - Refresh `node_modules` folder for updated dependencies.
-
-### AssertionError Update Notice
-
-Chai now uses [chaijs/assertion-error](https://github.com/chaijs/assertion-error) instead an internal
-constructor. This will allow for further iteration/experimentation of the AssertionError constructor
-independant of Chai. Future plans include stack parsing for callsite support.
-
-This update constructor has a different constructor param signature that conforms more with the standard
-`Error` object. If your plugin throws and `AssertionError` directly you will need to update your plugin
-with the new signature.
-
-```js
-var AssertionError = require('chai').AssertionError;
-
-/**
- * previous
- *
- * @param {Object} options
- */
-
-throw new AssertionError({
-    message: 'An assertion error occurred'
-  , actual: actual
-  , expect: expect
-  , startStackFunction: arguments.callee
-  , showStack: true
-});
-
-/**
- * new
- *
- * @param {String} message
- * @param {Object} options
- * @param {Function} start stack function
- */
-
-throw new AssertionError('An assertion error occurred', {
-    actual: actual
-  , expect: expect
-  , showStack: true
-}, arguments.callee);
-
-// other signatures
-throw new AssertionError('An assertion error occurred');
-throw new AssertionError('An assertion error occurred', null, arguments.callee);
-```
-
-#### External Dependencies
-
-This is the first non-developement dependency for Chai. As Chai continues to evolve we will begin adding
-more; the next will likely be improved type detection and deep equality. With Chai's userbase continually growing
-there is an higher need for accountability and documentation. External dependencies will allow us to iterate and
-test on features independent from our interfaces.
-
-Note: The browser packaged version `chai.js` will ALWAYS contain all dependencies needed to run Chai.

-### New Assertions
-
-#### Array Members Inclusion
-
-Asserts that the target is a superset of `set`, or that the target and `set` have the same members.
-Order is not taken into account. Thanks to [@NickHeiner](https://github.com/NickHeiner) for the contribution.
-
-```js
-// (expect/should) full set
-expect([4, 2]).to.have.members([2, 4]);
-expect([5, 2]).to.not.have.members([5, 2, 1]);
-
-// (expect/should) inclusion
-expect([1, 2, 3]).to.include.members([3, 2]);
-expect([1, 2, 3]).to.not.include.members([3, 2, 8]);
-
-// (assert) full set
-assert.sameMembers([ 1, 2, 3 ], [ 2, 1, 3 ], 'same members');
-
-// (assert) inclusion
-assert.includeMembers([ 1, 2, 3 ], [ 2, 1 ], 'include members');
-
-```
-
-#### Non-inclusion for Assert Interface
-
-Most `assert` functions have a negative version, like `instanceOf()` has a corresponding `notInstaceOf()`.
-However `include()` did not have a corresponding `notInclude()`. This has been added.
-
-```js
-assert.notInclude([ 1, 2, 3 ], 8);
-assert.notInclude('foobar', 'baz');
-```

-
-Thank you to all who took time to contribute!
-
-### Other Bug Fixes
-
-- [#142](https://github.com/chaijs/chai/issues/142) `assert#include` will no longer silently pass on wrong-type haystack.
-- [#158](https://github.com/chaijs/chai/issues/158) `assert#notInclude` has been added.
-- Travis-CI now tests Node.js `v0.10.x`. Support for `v0.6.x` has been removed. `v0.8.x` is still tested as before.
-
-## 1.5.0 / 2013-02-03
-
-### Migration Requirements
-
-The following changes are required if you are upgrading from the previous version:
-
-- **Users:**
-  - _Update [2013-02-04]:_ Some users may notice a small subset of deep equality assertions will no longer pass. This is the result of
-  [#120](https://github.com/chaijs/chai/issues/120), an improvement to our deep equality algorithm. Users will need to revise their assertions
-  to be more granular should this occur. Further information: [#139](https://github.com/chaijs/chai/issues/139).
-- **Plugin Developers:**
-  - No changes required.
-- **Core Contributors:**
-  - Refresh `node_modules` folder for updated developement dependencies.

-### Usage Updates
-
-#### For Users
-
-**1. Component Support:** Chai now included the proper configuration to be installed as a
-[component](https://github.com/component/component). Component users are encouraged to consult
-[chaijs.com](http://chaijs.com) for the latest version number as using the master branch
-does not gaurantee stability.
-
-```js
-// relevant component.json
-  devDependencies: {
-    "chaijs/chai": "1.5.0"
-  }
-```
-
-Alternatively, bleeding-edge is available:
-
-    $ component install chaijs/chai
-
-**2. Configurable showDiff:** Some test runners (such as [mocha](http://visionmedia.github.com/mocha/))
-include support for showing the diff of strings and objects when an equality error occurs. Chai has
-already included support for this, however some users may not prefer this display behavior. To revert to
-no diff display, the following configuration is available:
-
-```js
-chai.Assertion.showDiff = false; // diff output disabled
-chai.Assertion.showDiff = true; // default, diff output enabled
-```
-
-#### For Plugin Developers
-
-**1. New Utility - type**: The new utility `.type()` is available as a better implementation of `typeof`
-that can be used cross-browser. It handles the inconsistencies of Array, `null`, and `undefined` detection.
-
-- **@param** _{Mixed}_ object to detect type of
-- **@return** _{String}_ object type
-
-```js
-chai.use(function (c, utils) {
-  // some examples
-  utils.type({}); // 'object'
-  utils.type(null); // `null'
-  utils.type(undefined); // `undefined`
-  utils.type([]); // `array`
-});
-```
-
-#### For Core Contributors
-
-**1. Browser Testing**: Browser testing of the `./chai.js` file is now available in the command line
-via PhantomJS. `make test` and Travis-CI will now also rebuild and test `./chai.js`. Consequently, all
-pull requests will now be browser tested in this way.
-
-_Note: Contributors opening pull requests should still NOT include the browser build._
-
-**2. SauceLabs Testing**: Early SauceLab support has been enabled with the file `./support/mocha-cloud.js`.
-Those interested in trying it out should create a free [Open Sauce](https://saucelabs.com/signup/plan) account
-and include their credentials in `./test/auth/sauce.json`.

-   * Assertion Constructor
-   *
-   * Creates object for chaining.
-   *
-   * `Assertion` objects contain metadata in the form of flags. Three flags can
-   * be assigned during instantiation by passing arguments to this constructor:
-   *
-   * - `object`: This flag contains the target of the assertion. For example, in
-   *   the assertion `expect(numKittens).to.equal(7);`, the `object` flag will
-   *   contain `numKittens` so that the `equal` assertion can reference it when
-   *   needed.
-   *
-   * - `message`: This flag contains an optional custom error message to be
-   *   prepended to the error message that's generated by the assertion when it
-   *   fails.
-   *
-   * - `ssfi`: This flag stands for "start stack function indicator". It
-   *   contains a function reference that serves as the starting point for
-   *   removing frames from the stack trace of the error that's created by the
-   *   assertion when it fails. The goal is to provide a cleaner stack trace to
-   *   end users by removing Chai's internal functions. Note that it only works
-   *   in environments that support `Error.captureStackTrace`, and only when
-   *   `Chai.config.includeStack` hasn't been set to `false`.
-   *
-   * - `lockSsfi`: This flag controls whether or not the given `ssfi` flag
-   *   should retain its current value, even as assertions are chained off of
-   *   this object. This is usually set to `true` when creating a new assertion
-   *   from within another assertion. It's also temporarily set to `true` before
-   *   an overwritten assertion gets called by the overwriting assertion.

-   * ### .include(val[, msg])
-   *
-   * When the target is a string, `.include` asserts that the given string `val`
-   * is a substring of the target.
-   *
-   *     expect('foobar').to.include('foo');
-   *
-   * When the target is an array, `.include` asserts that the given `val` is a
-   * member of the target.
-   *
-   *     expect([1, 2, 3]).to.include(2);
-   *
-   * When the target is an object, `.include` asserts that the given object
-   * `val`'s properties are a subset of the target's properties.
-   *
-   *     expect({a: 1, b: 2, c: 3}).to.include({a: 1, b: 2});
-   *
-   * When the target is a Set or WeakSet, `.include` asserts that the given `val` is a
-   * member of the target. SameValueZero equality algorithm is used.
-   *
-   *     expect(new Set([1, 2])).to.include(2);
-   *
-   * When the target is a Map, `.include` asserts that the given `val` is one of
-   * the values of the target. SameValueZero equality algorithm is used.
-   *
-   *     expect(new Map([['a', 1], ['b', 2]])).to.include(2);
-   *
-   * Because `.include` does different things based on the target's type, it's
-   * important to check the target's type before using `.include`. See the `.a`
-   * doc for info on testing a target's type.
-   *
-   *     expect([1, 2, 3]).to.be.an('array').that.includes(2);
-   *
-   * By default, strict (`===`) equality is used to compare array members and
-   * object properties. Add `.deep` earlier in the chain to use deep equality
-   * instead (WeakSet targets are not supported). See the `deep-eql` project
-   * page for info on the deep equality algorithm: https://github.com/chaijs/deep-eql.
-   *
-   *     // Target array deeply (but not strictly) includes `{a: 1}`
-   *     expect([{a: 1}]).to.deep.include({a: 1});
-   *     expect([{a: 1}]).to.not.include({a: 1});
-   *
-   *     // Target object deeply (but not strictly) includes `x: {a: 1}`
-   *     expect({x: {a: 1}}).to.deep.include({x: {a: 1}});
-   *     expect({x: {a: 1}}).to.not.include({x: {a: 1}});
-   *
-   * By default, all of the target's properties are searched when working with
-   * objects. This includes properties that are inherited and/or non-enumerable.
-   * Add `.own` earlier in the chain to exclude the target's inherited
-   * properties from the search.
-   *
-   *     Object.prototype.b = 2;
-   *
-   *     expect({a: 1}).to.own.include({a: 1});
-   *     expect({a: 1}).to.include({b: 2}).but.not.own.include({b: 2});
-   *
-   * Note that a target object is always only searched for `val`'s own
-   * enumerable properties.
-   *
-   * `.deep` and `.own` can be combined.
-   *
-   *     expect({a: {b: 2}}).to.deep.own.include({a: {b: 2}});
-   *
-   * Add `.nested` earlier in the chain to enable dot- and bracket-notation when
-   * referencing nested properties.
-   *
-   *     expect({a: {b: ['x', 'y']}}).to.nested.include({'a.b[1]': 'y'});
-   *
-   * If `.` or `[]` are part of an actual property name, they can be escaped by
-   * adding two backslashes before them.
-   *
-   *     expect({'.a': {'[b]': 2}}).to.nested.include({'\\.a.\\[b\\]': 2});
-   *
-   * `.deep` and `.nested` can be combined.
-   *
-   *     expect({a: {b: [{c: 3}]}}).to.deep.nested.include({'a.b[0]': {c: 3}});
-   *
-   * `.own` and `.nested` cannot be combined.
-   *
-   * Add `.not` earlier in the chain to negate `.include`.
-   *
-   *     expect('foobar').to.not.include('taco');
-   *     expect([1, 2, 3]).to.not.include(4);
-   * 
-   * However, it's dangerous to negate `.include` when the target is an object.
-   * The problem is that it creates uncertain expectations by asserting that the
-   * target object doesn't have all of `val`'s key/value pairs but may or may
-   * not have some of them. It's often best to identify the exact output that's
-   * expected, and then write an assertion that only accepts that exact output.
-   *
-   * When the target object isn't even expected to have `val`'s keys, it's
-   * often best to assert exactly that.
-   *
-   *     expect({c: 3}).to.not.have.any.keys('a', 'b'); // Recommended
-   *     expect({c: 3}).to.not.include({a: 1, b: 2}); // Not recommended
-   *
-   * When the target object is expected to have `val`'s keys, it's often best to
-   * assert that each of the properties has its expected value, rather than
-   * asserting that each property doesn't have one of many unexpected values.
-   *
-   *     expect({a: 3, b: 4}).to.include({a: 3, b: 4}); // Recommended
-   *     expect({a: 3, b: 4}).to.not.include({a: 1, b: 2}); // Not recommended
-   *
-   * `.include` accepts an optional `msg` argument which is a custom error
-   * message to show when the assertion fails. The message can also be given as
-   * the second argument to `expect`.
-   *
-   *     expect([1, 2, 3]).to.include(4, 'nooo why fail??');
-   *     expect([1, 2, 3], 'nooo why fail??').to.include(4);
-   *
-   * `.include` can also be used as a language chain, causing all `.members` and
-   * `.keys` assertions that follow in the chain to require the target to be a
-   * superset of the expected set, rather than an identical set. Note that
-   * `.members` ignores duplicates in the subset when `.include` is added.
-   *
-   *     // Target object's keys are a superset of ['a', 'b'] but not identical
-   *     expect({a: 1, b: 2, c: 3}).to.include.all.keys('a', 'b');
-   *     expect({a: 1, b: 2, c: 3}).to.not.have.all.keys('a', 'b');
-   *
-   *     // Target array is a superset of [1, 2] but not identical
-   *     expect([1, 2, 3]).to.include.members([1, 2]);
-   *     expect([1, 2, 3]).to.not.have.members([1, 2]);
-   *
-   *     // Duplicates in the subset are ignored
-   *     expect([1, 2, 3]).to.include.members([1, 2, 2, 2]);
-   *
-   * Note that adding `.any` earlier in the chain causes the `.keys` assertion
-   * to ignore `.include`.
-   *
-   *     // Both assertions are identical
-   *     expect({a: 1}).to.include.any.keys('a', 'b');
-   *     expect({a: 1}).to.have.any.keys('a', 'b');

-   *
-   * When the target isn't expected to have a property with the given key
-   * `name`, it's often best to assert exactly that.

-   *
-   * When the target is expected to have a property with the given key `name`,
-   * it's often best to assert that the property has its expected value, rather
-   * than asserting that it doesn't have one of many unexpected values.
-   *
-   *     expect({a: 3}).to.have.property('a', 3); // Recommended
-   *     expect({a: 3}).to.not.have.property('a', 1); // Not recommended
-   *
-   * `.property` changes the target of any assertions that follow in the chain
-   * to be the value of the property from the original target object.
-   *
-   *     expect({a: 1}).to.have.property('a').that.is.a('number');
-   *
-   * `.property` accepts an optional `msg` argument which is a custom error
-   * message to show when the assertion fails. The message can also be given as
-   * the second argument to `expect`. When not providing `val`, only use the
-   * second form.
-   *
-   *     // Recommended
-   *     expect({a: 1}).to.have.property('a', 2, 'nooo why fail??');

-   *
-   *     expect({a: 1}).to.have.ownPropertyDescriptor('a');
-   *
-   * When `descriptor` is provided, `.ownPropertyDescriptor` also asserts that
-   * the property's descriptor is deeply equal to the given `descriptor`. See

-   *
-   *     expect({a: 1}).to.not.have.ownPropertyDescriptor('b');
-   * 
-   * However, it's dangerous to negate `.ownPropertyDescriptor` when providing

-   * asserting that the target either doesn't have a property descriptor with
-   * the given key `name`, or that it does have a property descriptor with the
-   * given key `name` but its not deeply equal to the given `descriptor`. It's
-   * often best to identify the exact output that's expected, and then write an
-   * assertion that only accepts that exact output.
-   *
-   * When the target isn't expected to have a property descriptor with the given
-   * key `name`, it's often best to assert exactly that.

-   *
-   * When the target is expected to have a property descriptor with the given
-   * key `name`, it's often best to assert that the property has its expected
-   * descriptor, rather than asserting that it doesn't have one of many
-   * unexpected descriptors.

-   *       writable: true,
-   *       value: 1,
-   *     });
-   *
-   * `.ownPropertyDescriptor` changes the target of any assertions that follow

-   * target object.
-   *
-   *     expect({a: 1}).to.have.ownPropertyDescriptor('a')
-   *       .that.has.property('enumerable', true);
-   *
-   * `.ownPropertyDescriptor` accepts an optional `msg` argument which is a
-   * custom error message to show when the assertion fails. The message can also
-   * be given as the second argument to `expect`. When not providing
-   * `descriptor`, only use the second form.

-   * ### .throw([errorLike], [errMsgMatcher], [msg])
-   *
-   * When no arguments are provided, `.throw` invokes the target function and
-   * asserts that an error is thrown.
-   * 
-   *     var badFn = function () { throw new TypeError('Illegal salmon!'); };
-   *
-   *     expect(badFn).to.throw();
-   *
-   * When one argument is provided, and it's an error constructor, `.throw`
-   * invokes the target function and asserts that an error is thrown that's an
-   * instance of that error constructor.
-   *
-   *     var badFn = function () { throw new TypeError('Illegal salmon!'); };
-   *
-   *     expect(badFn).to.throw(TypeError);
-   *
-   * When one argument is provided, and it's an error instance, `.throw` invokes
-   * the target function and asserts that an error is thrown that's strictly
-   * (`===`) equal to that error instance.
-   *
-   *     var err = new TypeError('Illegal salmon!');
-   *     var badFn = function () { throw err; };
-   *
-   *     expect(badFn).to.throw(err);
-   *
-   * When one argument is provided, and it's a string, `.throw` invokes the
-   * target function and asserts that an error is thrown with a message that
-   * contains that string.
-   *
-   *     var badFn = function () { throw new TypeError('Illegal salmon!'); };
-   *
-   *     expect(badFn).to.throw('salmon');
-   *
-   * When one argument is provided, and it's a regular expression, `.throw`
-   * invokes the target function and asserts that an error is thrown with a
-   * message that matches that regular expression.
-   *
-   *     var badFn = function () { throw new TypeError('Illegal salmon!'); };
-   *
-   *     expect(badFn).to.throw(/salmon/);
-   *
-   * When two arguments are provided, and the first is an error instance or
-   * constructor, and the second is a string or regular expression, `.throw`
-   * invokes the function and asserts that an error is thrown that fulfills both
-   * conditions as described above.
-   *
-   *     var err = new TypeError('Illegal salmon!');
-   *     var badFn = function () { throw err; };
-   *
-   *     expect(badFn).to.throw(TypeError, 'salmon');
-   *     expect(badFn).to.throw(TypeError, /salmon/);
-   *     expect(badFn).to.throw(err, 'salmon');
-   *     expect(badFn).to.throw(err, /salmon/);
-   *
-   * Add `.not` earlier in the chain to negate `.throw`.
-   *     
-   *     var goodFn = function () {};
-   *
-   *     expect(goodFn).to.not.throw();
-   * 
-   * However, it's dangerous to negate `.throw` when providing any arguments.
-   * The problem is that it creates uncertain expectations by asserting that the
-   * target either doesn't throw an error, or that it throws an error but of a
-   * different type than the given type, or that it throws an error of the given
-   * type but with a message that doesn't include the given string. It's often
-   * best to identify the exact output that's expected, and then write an
-   * assertion that only accepts that exact output.
-   *
-   * When the target isn't expected to throw an error, it's often best to assert
-   * exactly that.
-   *
-   *     var goodFn = function () {};
-   *
-   *     expect(goodFn).to.not.throw(); // Recommended
-   *     expect(goodFn).to.not.throw(ReferenceError, 'x'); // Not recommended
-   *
-   * When the target is expected to throw an error, it's often best to assert
-   * that the error is of its expected type, and has a message that includes an
-   * expected string, rather than asserting that it doesn't have one of many
-   * unexpected types, and doesn't have a message that includes some string.
-   *
-   *     var badFn = function () { throw new TypeError('Illegal salmon!'); };
-   *
-   *     expect(badFn).to.throw(TypeError, 'salmon'); // Recommended
-   *     expect(badFn).to.not.throw(ReferenceError, 'x'); // Not recommended
-   *
-   * `.throw` changes the target of any assertions that follow in the chain to
-   * be the error object that's thrown.
-   *
-   *     var err = new TypeError('Illegal salmon!');
-   *     err.code = 42;
-   *     var badFn = function () { throw err; };
-   *
-   *     expect(badFn).to.throw(TypeError).with.property('code', 42);
-   *
-   * `.throw` accepts an optional `msg` argument which is a custom error message
-   * to show when the assertion fails. The message can also be given as the
-   * second argument to `expect`. When not providing two arguments, always use
-   * the second form.
-   *
-   *     var goodFn = function () {};
-   *
-   *     expect(goodFn).to.throw(TypeError, 'x', 'nooo why fail??');
-   *     expect(goodFn, 'nooo why fail??').to.throw();
-   *
-   * Due to limitations in ES5, `.throw` may not always work as expected when
-   * using a transpiler such as Babel or TypeScript. In particular, it may
-   * produce unexpected results when subclassing the built-in `Error` object and
-   * then passing the subclassed constructor to `.throw`. See your transpiler's
-   * docs for details:
-   *
-   * - ([Babel](https://babeljs.io/docs/usage/caveats/#classes))
-   * - ([TypeScript](https://github.com/Microsoft/TypeScript/wiki/Breaking-Changes#extending-built-ins-like-error-array-and-map-may-no-longer-work))
-   *
-   * Beware of some common mistakes when using the `throw` assertion. One common
-   * mistake is to accidentally invoke the function yourself instead of letting
-   * the `throw` assertion invoke the function for you. For example, when
-   * testing if a function named `fn` throws, provide `fn` instead of `fn()` as
-   * the target for the assertion.
-   *
-   *     expect(fn).to.throw();     // Good! Tests `fn` as desired
-   *     expect(fn()).to.throw();   // Bad! Tests result of `fn()`, not `fn`
-   *
-   * If you need to assert that your function `fn` throws when passed certain
-   * arguments, then wrap a call to `fn` inside of another function.
-   *
-   *     expect(function () { fn(42); }).to.throw();  // Function expression
-   *     expect(() => fn(42)).to.throw();             // ES6 arrow function
-   *
-   * Another common mistake is to provide an object method (or any stand-alone
-   * function that relies on `this`) as the target of the assertion. Doing so is
-   * problematic because the `this` context will be lost when the function is
-   * invoked by `.throw`; there's no way for it to know what `this` is supposed
-   * to be. There are two ways around this problem. One solution is to wrap the
-   * method or function call inside of another function. Another solution is to
-   * use `bind`.
-   *
-   *     expect(function () { cat.meow(); }).to.throw();  // Function expression
-   *     expect(() => cat.meow()).to.throw();             // ES6 arrow function
-   *     expect(cat.meow.bind(cat)).to.throw();           // Bind
-   *
-   * Finally, it's worth mentioning that it's a best practice in JavaScript to
-   * only throw `Error` and derivatives of `Error` such as `ReferenceError`,
-   * `TypeError`, and user-defined objects that extend `Error`. No other type of
-   * value will generate a stack trace when initialized. With that said, the
-   * `throw` assertion does technically support any type of value being thrown,
-   * not just `Error` and its derivatives.
-   *
-   * The aliases `.throws` and `.Throw` can be used interchangeably with
-   * `.throw`.

- * ### .addLengthGuard(fn, assertionName, isChainable)

- * Define `length` as a getter on the given uninvoked method assertion. The
- * getter acts as a guard against chaining `length` directly off of an uninvoked
- * method assertion, which is a problem because it references `function`'s
- * built-in `length` property instead of Chai's `length` assertion. When the
- * getter catches the user making this mistake, it throws an error with a
- * helpful message.
- *
- * There are two ways in which this mistake can be made. The first way is by
- * chaining the `length` assertion directly off of an uninvoked chainable
- * method. In this case, Chai suggests that the user use `lengthOf` instead. The
- * second way is by chaining the `length` assertion directly off of an uninvoked
- * non-chainable method. Non-chainable methods must be invoked prior to
- * chaining. In this case, Chai suggests that the user consult the docs for the
- * given assertion.
- *
- * If the `length` property of functions is unconfigurable, then return `fn`
- * without modification.
- *
- * Note that in ES6, the function's `length` property is configurable, so once
- * support for legacy environments is dropped, Chai's `length` property can
- * replace the built-in function's `length` property, and this length guard will
- * no longer be necessary. In the mean time, maintaining consistency across all
- * environments is the priority.

-   * Assertion Constructor
-   *
-   * Creates object for chaining.
-   *
-   * `Assertion` objects contain metadata in the form of flags. Three flags can
-   * be assigned during instantiation by passing arguments to this constructor:
-   *
-   * - `object`: This flag contains the target of the assertion. For example, in
-   *   the assertion `expect(numKittens).to.equal(7);`, the `object` flag will
-   *   contain `numKittens` so that the `equal` assertion can reference it when
-   *   needed.
-   *
-   * - `message`: This flag contains an optional custom error message to be
-   *   prepended to the error message that's generated by the assertion when it
-   *   fails.
-   *
-   * - `ssfi`: This flag stands for "start stack function indicator". It
-   *   contains a function reference that serves as the starting point for
-   *   removing frames from the stack trace of the error that's created by the
-   *   assertion when it fails. The goal is to provide a cleaner stack trace to
-   *   end users by removing Chai's internal functions. Note that it only works
-   *   in environments that support `Error.captureStackTrace`, and only when
-   *   `Chai.config.includeStack` hasn't been set to `false`.
-   *
-   * - `lockSsfi`: This flag controls whether or not the given `ssfi` flag
-   *   should retain its current value, even as assertions are chained off of
-   *   this object. This is usually set to `true` when creating a new assertion
-   *   from within another assertion. It's also temporarily set to `true` before
-   *   an overwritten assertion gets called by the overwriting assertion.

-   * ### .include(val[, msg])
-   *
-   * When the target is a string, `.include` asserts that the given string `val`
-   * is a substring of the target.
-   *
-   *     expect('foobar').to.include('foo');
-   *
-   * When the target is an array, `.include` asserts that the given `val` is a
-   * member of the target.
-   *
-   *     expect([1, 2, 3]).to.include(2);
-   *
-   * When the target is an object, `.include` asserts that the given object
-   * `val`'s properties are a subset of the target's properties.
-   *
-   *     expect({a: 1, b: 2, c: 3}).to.include({a: 1, b: 2});
-   *
-   * When the target is a Set or WeakSet, `.include` asserts that the given `val` is a
-   * member of the target. SameValueZero equality algorithm is used.
-   *
-   *     expect(new Set([1, 2])).to.include(2);
-   *
-   * When the target is a Map, `.include` asserts that the given `val` is one of
-   * the values of the target. SameValueZero equality algorithm is used.
-   *
-   *     expect(new Map([['a', 1], ['b', 2]])).to.include(2);
-   *
-   * Because `.include` does different things based on the target's type, it's
-   * important to check the target's type before using `.include`. See the `.a`
-   * doc for info on testing a target's type.
-   *
-   *     expect([1, 2, 3]).to.be.an('array').that.includes(2);
-   *
-   * By default, strict (`===`) equality is used to compare array members and
-   * object properties. Add `.deep` earlier in the chain to use deep equality
-   * instead (WeakSet targets are not supported). See the `deep-eql` project
-   * page for info on the deep equality algorithm: https://github.com/chaijs/deep-eql.
-   *
-   *     // Target array deeply (but not strictly) includes `{a: 1}`
-   *     expect([{a: 1}]).to.deep.include({a: 1});
-   *     expect([{a: 1}]).to.not.include({a: 1});
-   *
-   *     // Target object deeply (but not strictly) includes `x: {a: 1}`
-   *     expect({x: {a: 1}}).to.deep.include({x: {a: 1}});
-   *     expect({x: {a: 1}}).to.not.include({x: {a: 1}});
-   *
-   * By default, all of the target's properties are searched when working with
-   * objects. This includes properties that are inherited and/or non-enumerable.
-   * Add `.own` earlier in the chain to exclude the target's inherited
-   * properties from the search.
-   *
-   *     Object.prototype.b = 2;
-   *
-   *     expect({a: 1}).to.own.include({a: 1});
-   *     expect({a: 1}).to.include({b: 2}).but.not.own.include({b: 2});
-   *
-   * Note that a target object is always only searched for `val`'s own
-   * enumerable properties.
-   *
-   * `.deep` and `.own` can be combined.
-   *
-   *     expect({a: {b: 2}}).to.deep.own.include({a: {b: 2}});
-   *
-   * Add `.nested` earlier in the chain to enable dot- and bracket-notation when
-   * referencing nested properties.
-   *
-   *     expect({a: {b: ['x', 'y']}}).to.nested.include({'a.b[1]': 'y'});
-   *
-   * If `.` or `[]` are part of an actual property name, they can be escaped by
-   * adding two backslashes before them.
-   *
-   *     expect({'.a': {'[b]': 2}}).to.nested.include({'\\.a.\\[b\\]': 2});
-   *
-   * `.deep` and `.nested` can be combined.
-   *
-   *     expect({a: {b: [{c: 3}]}}).to.deep.nested.include({'a.b[0]': {c: 3}});
-   *
-   * `.own` and `.nested` cannot be combined.
-   *
-   * Add `.not` earlier in the chain to negate `.include`.
-   *
-   *     expect('foobar').to.not.include('taco');
-   *     expect([1, 2, 3]).to.not.include(4);
-   * 
-   * However, it's dangerous to negate `.include` when the target is an object.
-   * The problem is that it creates uncertain expectations by asserting that the
-   * target object doesn't have all of `val`'s key/value pairs but may or may
-   * not have some of them. It's often best to identify the exact output that's
-   * expected, and then write an assertion that only accepts that exact output.
-   *
-   * When the target object isn't even expected to have `val`'s keys, it's
-   * often best to assert exactly that.
-   *
-   *     expect({c: 3}).to.not.have.any.keys('a', 'b'); // Recommended
-   *     expect({c: 3}).to.not.include({a: 1, b: 2}); // Not recommended
-   *
-   * When the target object is expected to have `val`'s keys, it's often best to
-   * assert that each of the properties has its expected value, rather than
-   * asserting that each property doesn't have one of many unexpected values.
-   *
-   *     expect({a: 3, b: 4}).to.include({a: 3, b: 4}); // Recommended
-   *     expect({a: 3, b: 4}).to.not.include({a: 1, b: 2}); // Not recommended
-   *
-   * `.include` accepts an optional `msg` argument which is a custom error
-   * message to show when the assertion fails. The message can also be given as
-   * the second argument to `expect`.
-   *
-   *     expect([1, 2, 3]).to.include(4, 'nooo why fail??');
-   *     expect([1, 2, 3], 'nooo why fail??').to.include(4);
-   *
-   * `.include` can also be used as a language chain, causing all `.members` and
-   * `.keys` assertions that follow in the chain to require the target to be a
-   * superset of the expected set, rather than an identical set. Note that
-   * `.members` ignores duplicates in the subset when `.include` is added.
-   *
-   *     // Target object's keys are a superset of ['a', 'b'] but not identical
-   *     expect({a: 1, b: 2, c: 3}).to.include.all.keys('a', 'b');
-   *     expect({a: 1, b: 2, c: 3}).to.not.have.all.keys('a', 'b');
-   *
-   *     // Target array is a superset of [1, 2] but not identical
-   *     expect([1, 2, 3]).to.include.members([1, 2]);
-   *     expect([1, 2, 3]).to.not.have.members([1, 2]);
-   *
-   *     // Duplicates in the subset are ignored
-   *     expect([1, 2, 3]).to.include.members([1, 2, 2, 2]);
-   *
-   * Note that adding `.any` earlier in the chain causes the `.keys` assertion
-   * to ignore `.include`.
-   *
-   *     // Both assertions are identical
-   *     expect({a: 1}).to.include.any.keys('a', 'b');
-   *     expect({a: 1}).to.have.any.keys('a', 'b');

-   * When the target is expected to have a property with the given key `name`,

-   * than asserting that it doesn't have one of many unexpected values.
-   *
-   *     expect({a: 3}).to.have.property('a', 3); // Recommended
-   *     expect({a: 3}).to.not.have.property('a', 1); // Not recommended
-   *
-   * `.property` changes the target of any assertions that follow in the chain
-   * to be the value of the property from the original target object.
-   *
-   *     expect({a: 1}).to.have.property('a').that.is.a('number');
-   *
-   * `.property` accepts an optional `msg` argument which is a custom error
-   * message to show when the assertion fails. The message can also be given as
-   * the second argument to `expect`. When not providing `val`, only use the
-   * second form.
-   *
-   *     // Recommended
-   *     expect({a: 1}).to.have.property('a', 2, 'nooo why fail??');

-   * ### .ownPropertyDescriptor(name[, descriptor[, msg]])
-   *
-   * Asserts that the target has its own property descriptor with the given key
-   * `name`. Enumerable and non-enumerable properties are included in the
-   * search.
-   *
-   *     expect({a: 1}).to.have.ownPropertyDescriptor('a');
-   *
-   * When `descriptor` is provided, `.ownPropertyDescriptor` also asserts that
-   * the property's descriptor is deeply equal to the given `descriptor`. See
-   * the `deep-eql` project page for info on the deep equality algorithm:
-   * https://github.com/chaijs/deep-eql.
-   *
-   *     expect({a: 1}).to.have.ownPropertyDescriptor('a', {
-   *       configurable: true,
-   *       enumerable: true,
-   *       writable: true,
-   *       value: 1,
-   *     });
-   *
-   * Add `.not` earlier in the chain to negate `.ownPropertyDescriptor`.
-   *
-   *     expect({a: 1}).to.not.have.ownPropertyDescriptor('b');
-   * 
-   * However, it's dangerous to negate `.ownPropertyDescriptor` when providing
-   * a `descriptor`. The problem is that it creates uncertain expectations by
-   * asserting that the target either doesn't have a property descriptor with
-   * the given key `name`, or that it does have a property descriptor with the
-   * given key `name` but its not deeply equal to the given `descriptor`. It's
-   * often best to identify the exact output that's expected, and then write an
-   * assertion that only accepts that exact output.
-   *
-   * When the target isn't expected to have a property descriptor with the given
-   * key `name`, it's often best to assert exactly that.
-   *
-   *     // Recommended
-   *     expect({b: 2}).to.not.have.ownPropertyDescriptor('a');

-   *       writable: true,
-   *       value: 1,
-   *     });
-   *
-   * When the target is expected to have a property descriptor with the given
-   * key `name`, it's often best to assert that the property has its expected
-   * descriptor, rather than asserting that it doesn't have one of many
-   * unexpected descriptors.
-   *
-   *     // Recommended
-   *     expect({a: 3}).to.have.ownPropertyDescriptor('a', {
-   *       configurable: true,

-   *       enumerable: true,
-   *       writable: true,
-   *       value: 1,
-   *     });
-   *
-   * `.ownPropertyDescriptor` changes the target of any assertions that follow
-   * in the chain to be the value of the property descriptor from the original
-   * target object.
-   *
-   *     expect({a: 1}).to.have.ownPropertyDescriptor('a')
-   *       .that.has.property('enumerable', true);
-   *
-   * `.ownPropertyDescriptor` accepts an optional `msg` argument which is a
-   * custom error message to show when the assertion fails. The message can also
-   * be given as the second argument to `expect`. When not providing
-   * `descriptor`, only use the second form.
-   *
-   *     // Recommended
-   *     expect({a: 1}).to.have.ownPropertyDescriptor('a', {
-   *       configurable: true,
-   *       enumerable: true,
-   *       writable: true,
-   *       value: 2,
-   *     }, 'nooo why fail??');
-   *
-   *     // Recommended
-   *     expect({a: 1}, 'nooo why fail??').to.have.ownPropertyDescriptor('a', {

-   *     expect({a: 1})
-   *       .to.have.ownPropertyDescriptor('b', undefined, 'nooo why fail??');
-   *
-   * The above assertion isn't the same thing as not providing `descriptor`.
-   * Instead, it's asserting that the target object has a `b` property

-   * ### .throw([errorLike], [errMsgMatcher], [msg])
-   *
-   * When no arguments are provided, `.throw` invokes the target function and
-   * asserts that an error is thrown.
-   * 
-   *     var badFn = function () { throw new TypeError('Illegal salmon!'); };
-   *
-   *     expect(badFn).to.throw();
-   *
-   * When one argument is provided, and it's an error constructor, `.throw`
-   * invokes the target function and asserts that an error is thrown that's an
-   * instance of that error constructor.
-   *
-   *     var badFn = function () { throw new TypeError('Illegal salmon!'); };
-   *
-   *     expect(badFn).to.throw(TypeError);
-   *
-   * When one argument is provided, and it's an error instance, `.throw` invokes
-   * the target function and asserts that an error is thrown that's strictly
-   * (`===`) equal to that error instance.
-   *
-   *     var err = new TypeError('Illegal salmon!');
-   *     var badFn = function () { throw err; };
-   *
-   *     expect(badFn).to.throw(err);
-   *
-   * When one argument is provided, and it's a string, `.throw` invokes the
-   * target function and asserts that an error is thrown with a message that
-   * contains that string.
-   *
-   *     var badFn = function () { throw new TypeError('Illegal salmon!'); };
-   *
-   *     expect(badFn).to.throw('salmon');
-   *
-   * When one argument is provided, and it's a regular expression, `.throw`
-   * invokes the target function and asserts that an error is thrown with a
-   * message that matches that regular expression.
-   *
-   *     var badFn = function () { throw new TypeError('Illegal salmon!'); };
-   *
-   *     expect(badFn).to.throw(/salmon/);
-   *
-   * When two arguments are provided, and the first is an error instance or
-   * constructor, and the second is a string or regular expression, `.throw`
-   * invokes the function and asserts that an error is thrown that fulfills both
-   * conditions as described above.
-   *
-   *     var err = new TypeError('Illegal salmon!');
-   *     var badFn = function () { throw err; };
-   *
-   *     expect(badFn).to.throw(TypeError, 'salmon');
-   *     expect(badFn).to.throw(TypeError, /salmon/);
-   *     expect(badFn).to.throw(err, 'salmon');
-   *     expect(badFn).to.throw(err, /salmon/);
-   *
-   * Add `.not` earlier in the chain to negate `.throw`.
-   *     
-   *     var goodFn = function () {};
-   *
-   *     expect(goodFn).to.not.throw();
-   * 
-   * However, it's dangerous to negate `.throw` when providing any arguments.
-   * The problem is that it creates uncertain expectations by asserting that the
-   * target either doesn't throw an error, or that it throws an error but of a
-   * different type than the given type, or that it throws an error of the given
-   * type but with a message that doesn't include the given string. It's often
-   * best to identify the exact output that's expected, and then write an
-   * assertion that only accepts that exact output.
-   *
-   * When the target isn't expected to throw an error, it's often best to assert
-   * exactly that.
-   *
-   *     var goodFn = function () {};
-   *
-   *     expect(goodFn).to.not.throw(); // Recommended
-   *     expect(goodFn).to.not.throw(ReferenceError, 'x'); // Not recommended
-   *
-   * When the target is expected to throw an error, it's often best to assert
-   * that the error is of its expected type, and has a message that includes an
-   * expected string, rather than asserting that it doesn't have one of many
-   * unexpected types, and doesn't have a message that includes some string.
-   *
-   *     var badFn = function () { throw new TypeError('Illegal salmon!'); };
-   *
-   *     expect(badFn).to.throw(TypeError, 'salmon'); // Recommended
-   *     expect(badFn).to.not.throw(ReferenceError, 'x'); // Not recommended
-   *
-   * `.throw` changes the target of any assertions that follow in the chain to
-   * be the error object that's thrown.
-   *
-   *     var err = new TypeError('Illegal salmon!');
-   *     err.code = 42;
-   *     var badFn = function () { throw err; };
-   *
-   *     expect(badFn).to.throw(TypeError).with.property('code', 42);
-   *
-   * `.throw` accepts an optional `msg` argument which is a custom error message
-   * to show when the assertion fails. The message can also be given as the
-   * second argument to `expect`. When not providing two arguments, always use
-   * the second form.
-   *
-   *     var goodFn = function () {};
-   *
-   *     expect(goodFn).to.throw(TypeError, 'x', 'nooo why fail??');
-   *     expect(goodFn, 'nooo why fail??').to.throw();
-   *
-   * Due to limitations in ES5, `.throw` may not always work as expected when
-   * using a transpiler such as Babel or TypeScript. In particular, it may
-   * produce unexpected results when subclassing the built-in `Error` object and
-   * then passing the subclassed constructor to `.throw`. See your transpiler's
-   * docs for details:
-   *
-   * - ([Babel](https://babeljs.io/docs/usage/caveats/#classes))
-   * - ([TypeScript](https://github.com/Microsoft/TypeScript/wiki/Breaking-Changes#extending-built-ins-like-error-array-and-map-may-no-longer-work))
-   *
-   * Beware of some common mistakes when using the `throw` assertion. One common
-   * mistake is to accidentally invoke the function yourself instead of letting
-   * the `throw` assertion invoke the function for you. For example, when
-   * testing if a function named `fn` throws, provide `fn` instead of `fn()` as
-   * the target for the assertion.
-   *
-   *     expect(fn).to.throw();     // Good! Tests `fn` as desired
-   *     expect(fn()).to.throw();   // Bad! Tests result of `fn()`, not `fn`
-   *
-   * If you need to assert that your function `fn` throws when passed certain
-   * arguments, then wrap a call to `fn` inside of another function.
-   *
-   *     expect(function () { fn(42); }).to.throw();  // Function expression
-   *     expect(() => fn(42)).to.throw();             // ES6 arrow function
-   *
-   * Another common mistake is to provide an object method (or any stand-alone
-   * function that relies on `this`) as the target of the assertion. Doing so is
-   * problematic because the `this` context will be lost when the function is
-   * invoked by `.throw`; there's no way for it to know what `this` is supposed
-   * to be. There are two ways around this problem. One solution is to wrap the
-   * method or function call inside of another function. Another solution is to
-   * use `bind`.
-   *
-   *     expect(function () { cat.meow(); }).to.throw();  // Function expression
-   *     expect(() => cat.meow()).to.throw();             // ES6 arrow function
-   *     expect(cat.meow.bind(cat)).to.throw();           // Bind
-   *
-   * Finally, it's worth mentioning that it's a best practice in JavaScript to
-   * only throw `Error` and derivatives of `Error` such as `ReferenceError`,
-   * `TypeError`, and user-defined objects that extend `Error`. No other type of
-   * value will generate a stack trace when initialized. With that said, the
-   * `throw` assertion does technically support any type of value being thrown,
-   * not just `Error` and its derivatives.
-   *
-   * The aliases `.throws` and `.Throw` can be used interchangeably with
-   * `.throw`.

-   * By default, members are compared using strict (`===`) equality. Add `.deep`

-   * expected members. Note that duplicates are ignored in the subset when
-   * `.include` is added.

-  - strikethrough

-  - rainbow
-  - zebra
-  - america
-  - trap
-  - random
-
-
-## Usage
-
-By popular demand, `colors` now ships with two types of usages!
-
-The super nifty way
-
-```js
-var colors = require('colors');
-
-console.log('hello'.green); // outputs green text
-console.log('i like cake and pies'.underline.red) // outputs red underlined text
-console.log('inverse the color'.inverse); // inverses the color
-console.log('OMG Rainbows!'.rainbow); // rainbow
-console.log('Run the trap'.trap); // Drops the bass
-
-```
-
-or a slightly less nifty way which doesn't extend `String.prototype`
-
-```js
-var colors = require('colors/safe');
-
-console.log(colors.green('hello')); // outputs green text
-console.log(colors.red.underline('i like cake and pies')) // outputs red underlined text
-console.log(colors.inverse('inverse the color')); // inverses the color
-console.log(colors.rainbow('OMG Rainbows!')); // rainbow
-console.log(colors.trap('Run the trap')); // Drops the bass
-
-```
-
-I prefer the first way. Some people seem to be afraid of extending `String.prototype` and prefer the second way. 
-
-If you are writing good code you will never have an issue with the first approach. If you really don't want to touch `String.prototype`, the second usage will not touch `String` native object.
-
-## Disabling Colors
-
-To disable colors you can pass the following arguments in the command line to your application:
-
-```bash
-node myapp.js --no-color
-```
-
-## Console.log [string substitution](http://nodejs.org/docs/latest/api/console.html#console_console_log_data)
-
-```js
-var name = 'Marak';
-console.log(colors.green('Hello %s'), name);
-// outputs -> 'Hello Marak'
-```
-
-## Custom themes
-
-### Using standard API
-
-```js
-
-var colors = require('colors');
-
-colors.setTheme({
-  silly: 'rainbow',
-  input: 'grey',
-  verbose: 'cyan',
-  prompt: 'grey',
-  info: 'green',
-  data: 'grey',
-  help: 'cyan',
-  warn: 'yellow',
-  debug: 'blue',
-  error: 'red'
-});
-
-// outputs red text
-console.log("this is an error".error);
-
-// outputs yellow text
-console.log("this is a warning".warn);
-```
-
-### Using string safe API
-
-```js
-var colors = require('colors/safe');
-
-// set single property
-var error = colors.red;
-error('this is red');
-
-// set theme
-colors.setTheme({
-  silly: 'rainbow',
-  input: 'grey',
-  verbose: 'cyan',
-  prompt: 'grey',
-  info: 'green',
-  data: 'grey',
-  help: 'cyan',
-  warn: 'yellow',
-  debug: 'blue',
-  error: 'red'
-});
-
-// outputs red text
-console.log(colors.error("this is an error"));
-
-// outputs yellow text
-console.log(colors.warn("this is a warning"));
-```
-
-*Protip: There is a secret undocumented style in `colors`. If you find the style you can summon him.*

-## Development
-
-You might want to know that:
-
-- Mocha is the *most-depended-upon* module on npm (source: [libraries.io](https://libraries.io/search?order=desc&platforms=NPM&sort=dependents_count)), and
-- Mocha is an *independent* open-source project, maintained exclusively by volunteers.
-
-You might want to help:
-
-- New to contributing to Mocha?  Check out this list of [good first issues](https://github.com/mochajs/mocha/issues?q=is%3Aissue+is%3Aopen+label%3Agood-first-issue)
-- Mocha could use a hand with [these issues](https://github.com/mochajs/mocha/issues?q=is%3Aissue+is%3Aopen+label%3A%22help+wanted%22)
-- The [maintainer's handbook](https://github.com/mochajs/mocha/blob/master/MAINTAINERS.md) explains how things get done
-
-Finally, come [chat with the maintainers](https://gitter.im/mochajs/contributors) on Gitter if you want to help with:
-
-- Triaging issues, answering questions
-- Review, merging, and closing pull requests
-- Other project-maintenance-y things

-
-// a transform stream is a readable/writable stream where you do
-// something with the data.  Sometimes it's called a "filter",
-// but that's not a great name for it, since that implies a thing where
-// some bits pass through, and others are simply ignored.  (That would
-// be a valid example of a transform, of course.)
-//
-// While the output is causally related to the input, it's not a
-// necessarily symmetric or synchronous transformation.  For example,
-// a zlib stream might take multiple plain-text writes(), and then
-// emit a single compressed chunk some time in the future.
-//
-// Here's how this works:
-//
-// The Transform stream has all the aspects of the readable and writable
-// stream classes.  When you write(chunk), that calls _write(chunk,cb)
-// internally, and returns false if there's a lot of pending writes
-// buffered up.  When you call read(), that calls _read(n) until
-// there's enough pending readable data buffered up.
-//
-// In a transform stream, the written data is placed in a buffer.  When
-// _read(n) is called, it transforms the queued up data, calling the
-// buffered _write cb's as it consumes chunks.  If consuming a single
-// written chunk would result in multiple output chunks, then the first
-// outputted bit calls the readcb, and subsequent chunks just go into
-// the read buffer, and will cause it to emit 'readable' if necessary.
-//
-// This way, back-pressure is actually determined by the reading side,
-// since _read has to be called to start processing a new chunk.  However,
-// a pathological inflate type of transform can cause excessive buffering
-// here.  For example, imagine a stream where every byte of input is
-// interpreted as an integer from 0-255, and then results in that many
-// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
-// 1kb of data being output.  In this case, you could write a very small
-// amount of input, and end up with a very large amount of output.  In
-// such a pathological inflating mechanism, there'd be no way to tell
-// the system to stop doing the transform.  A single 4MB write could
-// cause the system to run out of memory.
-//
-// However, even in such a pathological case, only a single written chunk
-// would be consumed, and then the rest would wait (un-transformed) until
-// the results of the previous transformed chunk were consumed.

-[![Build Status](https://api.travis-ci.org/tj/commander.js.svg?branch=master)](http://travis-ci.org/tj/commander.js)
-[![NPM Version](http://img.shields.io/npm/v/commander.svg?style=flat)](https://www.npmjs.org/package/commander)
-[![NPM Downloads](https://img.shields.io/npm/dm/commander.svg?style=flat)](https://www.npmjs.org/package/commander)
-[![Join the chat at https://gitter.im/tj/commander.js](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/tj/commander.js?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
-
-  The complete solution for [node.js](http://nodejs.org) command-line interfaces, inspired by Ruby's [commander](https://github.com/commander-rb/commander).  
-  [API documentation](http://tj.github.com/commander.js/)
-
-
-## Installation
-
-    $ npm install commander --save
-
-## Option parsing
-
- Options with commander are defined with the `.option()` method, also serving as documentation for the options. The example below parses args and options from `process.argv`, leaving remaining args as the `program.args` array which were not consumed by options.
-
-```js
-#!/usr/bin/env node
-
-/**
- * Module dependencies.
- */
-
-var program = require('commander');
-
-program
-  .version('0.1.0')
-  .option('-p, --peppers', 'Add peppers')
-  .option('-P, --pineapple', 'Add pineapple')
-  .option('-b, --bbq-sauce', 'Add bbq sauce')
-  .option('-c, --cheese [type]', 'Add the specified type of cheese [marble]', 'marble')
-  .parse(process.argv);
-
-console.log('you ordered a pizza with:');
-if (program.peppers) console.log('  - peppers');
-if (program.pineapple) console.log('  - pineapple');
-if (program.bbqSauce) console.log('  - bbq');
-console.log('  - %s cheese', program.cheese);
-```
-
- Short flags may be passed as a single arg, for example `-abc` is equivalent to `-a -b -c`. Multi-word options such as "--template-engine" are camel-cased, becoming `program.templateEngine` etc.
-
-
-## Coercion
-
-```js
-function range(val) {
-  return val.split('..').map(Number);
-}
-
-function list(val) {
-  return val.split(',');
-}
-
-function collect(val, memo) {
-  memo.push(val);
-  return memo;
-}
-
-function increaseVerbosity(v, total) {
-  return total + 1;
-}
-
-program
-  .version('0.1.0')
-  .usage('[options] ')
-  .option('-i, --integer ', 'An integer argument', parseInt)
-  .option('-f, --float ', 'A float argument', parseFloat)
-  .option('-r, --range ..', 'A range', range)
-  .option('-l, --list ', 'A list', list)
-  .option('-o, --optional [value]', 'An optional value')
-  .option('-c, --collect [value]', 'A repeatable value', collect, [])
-  .option('-v, --verbose', 'A value that can be increased', increaseVerbosity, 0)
-  .parse(process.argv);
-
-console.log(' int: %j', program.integer);
-console.log(' float: %j', program.float);
-console.log(' optional: %j', program.optional);
-program.range = program.range || [];
-console.log(' range: %j..%j', program.range[0], program.range[1]);
-console.log(' list: %j', program.list);
-console.log(' collect: %j', program.collect);
-console.log(' verbosity: %j', program.verbose);
-console.log(' args: %j', program.args);
-```
-
-## Regular Expression
-```js
-program
-  .version('0.1.0')
-  .option('-s --size ', 'Pizza size', /^(large|medium|small)$/i, 'medium')
-  .option('-d --drink [drink]', 'Drink', /^(coke|pepsi|izze)$/i)
-  .parse(process.argv);
-  
-console.log(' size: %j', program.size);
-console.log(' drink: %j', program.drink);
-```
-
-## Variadic arguments
-
- The last argument of a command can be variadic, and only the last argument.  To make an argument variadic you have to
- append `...` to the argument name.  Here is an example:
-
-```js
-#!/usr/bin/env node
-
-/**
- * Module dependencies.
- */
-
-var program = require('commander');
-
-program
-  .version('0.1.0')
-  .command('rmdir  [otherDirs...]')
-  .action(function (dir, otherDirs) {
-    console.log('rmdir %s', dir);
-    if (otherDirs) {
-      otherDirs.forEach(function (oDir) {
-        console.log('rmdir %s', oDir);
-      });
-    }
-  });
-
-program.parse(process.argv);
-```
-
- An `Array` is used for the value of a variadic argument.  This applies to `program.args` as well as the argument passed
- to your action as demonstrated above.
-
-## Specify the argument syntax
-
-```js
-#!/usr/bin/env node
-
-var program = require('commander');
-
-program
-  .version('0.1.0')
-  .arguments(' [env]')
-  .action(function (cmd, env) {
-     cmdValue = cmd;
-     envValue = env;
-  });
-
-program.parse(process.argv);
-
-if (typeof cmdValue === 'undefined') {
-   console.error('no command given!');
-   process.exit(1);
-}
-console.log('command:', cmdValue);
-console.log('environment:', envValue || "no environment given");
-```
-Angled brackets (e.g. ``) indicate required input. Square brackets (e.g. `[env]`) indicate optional input.
-
-## Git-style sub-commands
-
-```js
-// file: ./examples/pm
-var program = require('commander');
-
-program
-  .version('0.1.0')
-  .command('install [name]', 'install one or more packages')
-  .command('search [query]', 'search with optional query')
-  .command('list', 'list packages installed', {isDefault: true})
-  .parse(process.argv);
-```
-
-When `.command()` is invoked with a description argument, no `.action(callback)` should be called to handle sub-commands, otherwise there will be an error. This tells commander that you're going to use separate executables for sub-commands, much like `git(1)` and other popular tools.  
-The commander will try to search the executables in the directory of the entry script (like `./examples/pm`) with the name `program-command`, like `pm-install`, `pm-search`.
-
-Options can be passed with the call to `.command()`. Specifying `true` for `opts.noHelp` will remove the option from the generated help output. Specifying `true` for `opts.isDefault` will run the subcommand if no other subcommand is specified.
-
-If the program is designed to be installed globally, make sure the executables have proper modes, like `755`.
-
-### `--harmony`
-
-You can enable `--harmony` option in two ways:
-* Use `#! /usr/bin/env node --harmony` in the sub-commands scripts. Note some os version don’t support this pattern.
-* Use the `--harmony` option when call the command, like `node --harmony examples/pm publish`. The `--harmony` option will be preserved when spawning sub-command process.
-
-## Automated --help
-
- The help information is auto-generated based on the information commander already knows about your program, so the following `--help` info is for free:
-
-```  
- $ ./examples/pizza --help
-
-   Usage: pizza [options]
-
-   An application for pizzas ordering
-
-   Options:
-
-     -h, --help           output usage information
-     -V, --version        output the version number
-     -p, --peppers        Add peppers
-     -P, --pineapple      Add pineapple
-     -b, --bbq            Add bbq sauce
-     -c, --cheese   Add the specified type of cheese [marble]
-     -C, --no-cheese      You do not want any cheese
-
-```
-
-## Custom help
-
- You can display arbitrary `-h, --help` information
- by listening for "--help". Commander will automatically
- exit once you are done so that the remainder of your program
- does not execute causing undesired behaviours, for example
- in the following executable "stuff" will not output when
- `--help` is used.
-
-```js
-#!/usr/bin/env node
-
-/**
- * Module dependencies.
- */
-
-var program = require('commander');
-
-program
-  .version('0.1.0')
-  .option('-f, --foo', 'enable some foo')
-  .option('-b, --bar', 'enable some bar')
-  .option('-B, --baz', 'enable some baz');
-
-// must be before .parse() since
-// node's emit() is immediate
-
-program.on('--help', function(){
-  console.log('  Examples:');
-  console.log('');
-  console.log('    $ custom-help --help');
-  console.log('    $ custom-help -h');
-  console.log('');
-});
-
-program.parse(process.argv);
-
-console.log('stuff');
-```
-
-Yields the following help output when `node script-name.js -h` or `node script-name.js --help` are run:
-
-```
-
-Usage: custom-help [options]
-
-Options:
-
-  -h, --help     output usage information
-  -V, --version  output the version number
-  -f, --foo      enable some foo
-  -b, --bar      enable some bar
-  -B, --baz      enable some baz
-
-Examples:
-
-  $ custom-help --help
-  $ custom-help -h
-
-```
-
-## .outputHelp(cb)
-
-Output help information without exiting.
-Optional callback cb allows post-processing of help text before it is displayed.
-
-If you want to display help by default (e.g. if no command was provided), you can use something like:
-
-```js
-var program = require('commander');
-var colors = require('colors');
-
-program
-  .version('0.1.0')
-  .command('getstream [url]', 'get stream URL')
-  .parse(process.argv);
-
-  if (!process.argv.slice(2).length) {
-    program.outputHelp(make_red);
-  }
-
-function make_red(txt) {
-  return colors.red(txt); //display the help text in red on the console
-}
-```
-
-## .help(cb)
-
-  Output help information and exit immediately.
-  Optional callback cb allows post-processing of help text before it is displayed.
-
-## Examples
-
-```js
-var program = require('commander');
-
-program
-  .version('0.1.0')
-  .option('-C, --chdir ', 'change the working directory')
-  .option('-c, --config ', 'set config path. defaults to ./deploy.conf')
-  .option('-T, --no-tests', 'ignore test hook');
-
-program
-  .command('setup [env]')
-  .description('run setup commands for all envs')
-  .option("-s, --setup_mode [mode]", "Which setup mode to use")
-  .action(function(env, options){
-    var mode = options.setup_mode || "normal";
-    env = env || 'all';
-    console.log('setup for %s env(s) with %s mode', env, mode);
-  });
-
-program
-  .command('exec ')
-  .alias('ex')
-  .description('execute the given remote cmd')
-  .option("-e, --exec_mode ", "Which exec mode to use")
-  .action(function(cmd, options){
-    console.log('exec "%s" using %s mode', cmd, options.exec_mode);
-  }).on('--help', function() {
-    console.log('  Examples:');
-    console.log();
-    console.log('    $ deploy exec sequential');
-    console.log('    $ deploy exec async');
-    console.log();
-  });
-
-program
-  .command('*')
-  .action(function(env){
-    console.log('deploying "%s"', env);
-  });

-
-A tiny JavaScript debugging utility modelled after Node.js core's debugging
-technique. Works in Node.js and web browsers.
-
-## Installation
-
-```bash
-$ npm install debug
-```
-
-## Usage
-
-`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
-
-Example [_app.js_](./examples/node/app.js):
-
-```js
-var debug = require('debug')('http')
-  , http = require('http')
-  , name = 'My App';
-
-// fake app
-
-debug('booting %o', name);
-
-http.createServer(function(req, res){
-  debug(req.method + ' ' + req.url);
-  res.end('hello\n');
-}).listen(3000, function(){
-  debug('listening');
-});
-
-// fake worker of some kind
-
-require('./worker');
-```
-
-Example [_worker.js_](./examples/node/worker.js):
-
-```js
-var a = require('debug')('worker:a')
-  , b = require('debug')('worker:b');
-
-function work() {
-  a('doing lots of uninteresting work');
-  setTimeout(work, Math.random() * 1000);
-}
-
-work();
-
-function workb() {
-  b('doing some work');
-  setTimeout(workb, Math.random() * 2000);
-}
-
-workb();
-```
-
-The `DEBUG` environment variable is then used to enable these based on space or
-comma-delimited names.
-
-Here are some examples:
-
-screen shot 2017-08-08 at 12 53 04 pm
-screen shot 2017-08-08 at 12 53 38 pm
-screen shot 2017-08-08 at 12 53 25 pm
-
-#### Windows note
-
-On Windows the environment variable is set using the `set` command.
-
-```cmd
-set DEBUG=*,-not_this
-```
-
-Note that PowerShell uses different syntax to set environment variables.
-
-```cmd
-$env:DEBUG = "*,-not_this"
-```
-
-Then, run the program to be debugged as usual.
-
-
-## Namespace Colors
-
-Every debug instance has a color generated for it based on its namespace name.
-This helps when visually parsing the debug output to identify which debug instance
-a debug line belongs to.
-
-#### Node.js
-
-In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
-the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
-otherwise debug will only use a small handful of basic colors.
-
-
-
-#### Web Browser
-
-Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
-option. These are WebKit web inspectors, Firefox ([since version
-31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
-and the Firebug plugin for Firefox (any version).
-
-
-
-
-## Millisecond diff
-
-When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
-
-
-
-When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
-
-
-
-
-## Conventions
-
-If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser".  If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable.  You can then use it for normal output as well as debug output.
-
-## Wildcards
-
-The `*` character may be used as a wildcard. Suppose for example your library has
-debuggers named "connect:bodyParser", "connect:compress", "connect:session",
-instead of listing all three with
-`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do
-`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
-
-You can also exclude specific debuggers by prefixing them with a "-" character.
-For example, `DEBUG=*,-connect:*` would include all debuggers except those
-starting with "connect:".
-
-## Environment Variables
-
-When running through Node.js, you can set a few environment variables that will
-change the behavior of the debug logging:
-
-| Name      | Purpose                                         |
-|-----------|-------------------------------------------------|
-| `DEBUG`   | Enables/disables specific debugging namespaces. |
-| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY).  |
-| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
-| `DEBUG_DEPTH` | Object inspection depth.                    |
-| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
-
-
-__Note:__ The environment variables beginning with `DEBUG_` end up being
-converted into an Options object that gets used with `%o`/`%O` formatters.
-See the Node.js documentation for
-[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
-for the complete list.
-
-## Formatters
-
-Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting.
-Below are the officially supported formatters:
-
-| Formatter | Representation |
-|-----------|----------------|
-| `%O`      | Pretty-print an Object on multiple lines. |
-| `%o`      | Pretty-print an Object all on a single line. |
-| `%s`      | String. |
-| `%d`      | Number (both integer and float). |
-| `%j`      | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
-| `%%`      | Single percent sign ('%'). This does not consume an argument. |
-
-
-### Custom formatters
-
-You can add custom formatters by extending the `debug.formatters` object.
-For example, if you wanted to add support for rendering a Buffer as hex with
-`%h`, you could do something like:
-
-```js
-const createDebug = require('debug')
-createDebug.formatters.h = (v) => {
-  return v.toString('hex')
-}
-
-// …elsewhere
-const debug = createDebug('foo')
-debug('this is hex: %h', new Buffer('hello world'))
-//   foo this is hex: 68656c6c6f20776f726c6421 +0ms
-```
-
-
-## Browser Support
-
-You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
-or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
-if you don't want to build it yourself.
-
-Debug's enable state is currently persisted by `localStorage`.
-Consider the situation shown below where you have `worker:a` and `worker:b`,
-and wish to debug both. You can enable this using `localStorage.debug`:
-
-```js
-localStorage.debug = 'worker:*'
-```
-
-And then refresh the page.
-
-```js
-a = debug('worker:a');
-b = debug('worker:b');
-
-setInterval(function(){
-  a('doing some work');
-}, 1000);
-
-setInterval(function(){
-  b('doing some work');
-}, 1200);
-```
-
-
-## Output streams
-
-  By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
-
-Example [_stdout.js_](./examples/node/stdout.js):
-
-```js
-var debug = require('debug');
-var error = debug('app:error');
-
-// by default stderr is used
-error('goes to stderr!');
-
-var log = debug('app:log');
-// set this namespace to log via console.log
-log.log = console.log.bind(console); // don't forget to bind to console!
-log('goes to stdout');
-error('still goes to stderr!');
-
-// set all output to go via console.info
-// overrides all per-namespace log settings
-debug.log = console.info.bind(console);
-error('now goes to stdout via console.info');
-log('still goes to stdout, but via console.info now');
-```
-
-## Checking whether a debug target is enabled
-
-After you've created a debug instance, you can determine whether or not it is
-enabled by checking the `enabled` property:
-
-```javascript
-const debug = require('debug')('http');
-
-if (debug.enabled) {
-  // do stuff...
-}
-```
-
-You can also manually toggle this property to force the debug instance to be
-enabled or disabled.
