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.

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.

+ +For more information or to download plugins, view the [documentation](http://chaijs.com). + +## 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?

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. + +### Community Contributions + +- [#297](https://github.com/chaijs/chai/pull/297) Allow writing lint-friendly tests.

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 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.

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`. diff --git a/javascript/node_modules/chai/bower.json b/javascript/node_modules/chai/bower.json new file mode 100644 index 0000000..af2ee02 --- /dev/null +++ b/javascript/node_modules/chai/bower.json @@ -0,0 +1,26 @@ +{ + "name": "chai", + "description": "BDD/TDD assertion library for node.js and the browser.

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`.

+ +## What is Check-Error? + +Check-Error is a module which you can use to retrieve an Error's information such as its `message` or `constructor` name and also to check whether two Errors are compatible based on their messages, constructors or even instances. + +## Installation + +### Node.js + +`check-error` is available on [npm](http://npmjs.org). To install it, type: + + $ npm install check-error + +### Browsers + +You can also use it within the browser; install via npm and use the `check-error.js` file found within the download. For example: + +```html + +``` + +## Usage + +The primary export of `check-error` is an object which has the following methods: + +* `compatibleInstance(err, errorLike)` - Checks if an error is compatible with another `errorLike` object. If `errorLike` is an error instance we do a strict comparison, otherwise we return `false` by default, because instances of objects can only be compatible if they're both error instances. +* `compatibleConstructor(err, errorLike)` - Checks if an error's constructor is compatible with another `errorLike` object. If `err` has the same constructor as `errorLike` or if `err` is an instance of `errorLike`. +* `compatibleMessage(err, errMatcher)` - Checks if an error message is compatible with an `errMatcher` RegExp or String (we check if the message contains the String). +* `getConstructorName(errorLike)` - Retrieves the name of a constructor, an error's constructor or `errorLike` itself if it's not an error instance or constructor. +* `getMessage(err)` - Retrieves the message of an error or `err` itself if it's a String. If `err` or `err.message` is undefined we return an empty String. + +```js +var checkError = require('check-error'); +``` + +#### .compatibleInstance(err, errorLike) + +```js +var checkError = require('check-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.

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. + + +## Authors + + - TJ Holowaychuk + - Nathan Rajlich + - Andrew Rhyne + +## Backers + +Support us with a monthly donation and help us continue our activities.

+ +## What is Deep-Eql? + +Deep Eql is a module which you can use to determine if two objects are "deeply" equal - that is, rather than having referential equality (`a === b`), this module checks an object's keys recursively, until it finds primitives to check for referential equality. For more on equality in JavaScript, read [the comparison operators article on mdn](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators). + +As an example, take the following: + +```js +1 === 1 // These are primitives, they hold the same reference - they are strictly equal +1 == '1' // These are two different primitives, through type coercion they hold the same value - they are loosely equal +{ a: 1 } !== { a: 1 } // These are two different objects, they hold different references and so are not strictly equal - even though they hold the same values inside +{ a: 1 } != { a: 1 } // They have the same type, meaning loose equality performs the same check as strict equality - they are still not equal. + +var deepEql = require("deep-eql"); +deepEql({ a: 1 }, { a: 1 }) === true // deepEql can determine that they share the same keys and those keys share the same values, therefore they are deeply equal! +``` + +## Installation + +### Node.js + +`deep-eql` is available on [npm](http://npmjs.org). + + $ npm install deep-eql + +## Usage + +The primary export of `deep-eql` is function that can be given two objects to compare.

Passing an `err` will terminate further patch execution. + + Once all patches have been applied or an error occurs, the `options.complete(err)` callback is made. + +* `JsDiff.parsePatch(diffStr)` - Parses a patch into structured data + + Return a JSON object representation of the a patch, suitable for use with the `applyPatch` method. This parses to the same structure returned by `JsDiff.structuredPatch`. + +* `convertChangesToXML(changes)` - converts a list of changes to a serialized XML format + + +All methods above which accept the optional `callback` method will run in sync mode when that parameter is omitted and in async mode when supplied. This allows for larger diffs without blocking the event loop. This may be passed either directly as the final parameter or as the `callback` field in the `options` object. + +### Change Objects +Many of the methods above return change objects. These objects consist of the following fields: + +* `value`: Text content +* `added`: True if the value was inserted into the new string +* `removed`: True of the value was removed from the old string + +Note that some cases may omit a particular flag field. Comparison on the flag fields should always be done in a truthy or falsy manner. + +## Examples + +Basic example in Node + +```js +require('colors') +var jsdiff = require('diff'); + +var one = 'beep boop'; +var other = 'beep boob blah'; + +var diff = jsdiff.diffChars(one, other); + +diff.forEach(function(part){ + // green for additions, red for deletions + // grey for common parts + var color = part.added ? 'green' : + part.removed ? 'red' : 'grey'; + process.stderr.write(part.value[color]); +}); + +console.log() +``` +Running the above program should yield + +Node Example + +Basic example in a web page + +```html +

+
+## Compatibility
+
+[![Sauce Test Status](https://saucelabs.com/browser-matrix/jsdiff.svg)](https://saucelabs.com/u/jsdiff)
+
+jsdiff supports all ES3 environments with some known issues on IE8 and below. Under these browsers some diff algorithms such as word diff and others may fail due to lack of support for capturing groups in the `split` operation.

+# fs.realpath
+
+A backwards-compatible fs.realpath for Node v6 and above
+
+In Node v6, the JavaScript implementation of fs.realpath was replaced
+with a faster (but less resilient) native implementation.  That raises
+new and platform-specific errors and cannot handle long or excessively
+symlink-looping paths.
+
+This module handles those cases by detecting the new errors and
+falling back to the JavaScript implementation.  On versions of Node
+prior to v6, it has no effect.
+
+## USAGE
+
+```js
+var rp = require('fs.realpath')
+
+// async version
+rp.realpath(someLongAndLoopingPath, function (er, real) {
+  // the ELOOP was handled, but it was a bit slower
+})
+
+// sync version
+var real = rp.realpathSync(someLongAndLoopingPath)
+
+// monkeypatch at your own risk!
+// This replaces the fs.realpath/fs.realpathSync builtins
+rp.monkeypatch()
+
+// un-do the monkeypatching
+rp.unmonkeypatch()
+```

+## What is get-func-name?
+
+This is a module to retrieve a function's name securely and consistently both in NodeJS and the browser.
+
+## Installation
+
+### Node.js
+
+`get-func-name` is available on [npm](http://npmjs.org). To install it, type:
+
+    $ npm install get-func-name
+
+### Browsers
+
+You can also use it within the browser; install via npm and use the `get-func-name.js` file found within the download. For example:
+
+```html
+
+```
+
+## Usage
+
+The module `get-func-name` exports the following method:
+
+* `getFuncName(fn)` - Returns the name of a function.
+
+```js
+var getFuncName = require('get-func-name');
+```
+
+#### .getFuncName(fun)
+
+```js
+var getFuncName = require('get-func-name');
+
+var unknownFunction = function myCoolFunction(word) {
+   return word + 'is cool'; 
+};
+
+var anonymousFunction = (function () {
+    return function () {};
+}());
+
+getFuncName(unknownFunction) // 'myCoolFunction'
+getFuncName(anonymousFunction) // ''
+```

+# Glob
+
+Match files using the patterns the shell uses, like stars and stuff.
+
+[![Build Status](https://travis-ci.org/isaacs/node-glob.svg?branch=master)](https://travis-ci.org/isaacs/node-glob/) [![Build Status](https://ci.appveyor.com/api/projects/status/kd7f3yftf7unxlsx?svg=true)](https://ci.appveyor.com/project/isaacs/node-glob) [![Coverage Status](https://coveralls.io/repos/isaacs/node-glob/badge.svg?branch=master&service=github)](https://coveralls.io/github/isaacs/node-glob?branch=master)
+
+This is a glob implementation in JavaScript.  It uses the `minimatch`
+library to do its matching.
+
+![](oh-my-glob.gif)
+
+## Usage
+
+Install with npm
+
+```
+npm i glob
+```
+
+```javascript
+var glob = require("glob")
+
+// options is optional
+glob("**/*.js", options, function (er, files) {
+  // files is an array of filenames.
+  // If the `nonull` option is set, and nothing
+  // was found, then files is ["**/*.js"]
+  // er is an error object or null.
+})
+```
+
+## Glob Primer
+
+"Globs" are the patterns you type when you do stuff like `ls *.js` on
+the command line, or put `build/*` in a `.gitignore` file.
+
+Before parsing the path part patterns, braced sections are expanded
+into a set.  Braced sections start with `{` and end with `}`, with any
+number of comma-delimited sections within.  Braced sections may contain
+slash characters, so `a{/b/c,bcd}` would expand into `a/b/c` and `abcd`.
+
+The following characters have special magic meaning when used in a
+path portion:
+
+* `*` Matches 0 or more characters in a single path portion
+* `?` Matches 1 character
+* `[...]` Matches a range of characters, similar to a RegExp range.
+  If the first character of the range is `!` or `^` then it matches
+  any character not in the range.
+* `!(pattern|pattern|pattern)` Matches anything that does not match
+  any of the patterns provided.
+* `?(pattern|pattern|pattern)` Matches zero or one occurrence of the
+  patterns provided.
+* `+(pattern|pattern|pattern)` Matches one or more occurrences of the
+  patterns provided.
+* `*(a|b|c)` Matches zero or more occurrences of the patterns provided
+* `@(pattern|pat*|pat?erN)` Matches exactly one of the patterns
+  provided
+* `**` If a "globstar" is alone in a path portion, then it matches
+  zero or more directories and subdirectories searching for matches.
+  It does not crawl symlinked directories.
+
+### Dots
+
+If a file or directory path portion has a `.` as the first character,
+then it will not match any glob pattern unless that pattern's
+corresponding path part also has a `.` as its first character.
+
+For example, the pattern `a/.*/c` would match the file at `a/.b/c`.
+However the pattern `a/*/c` would not, because `*` does not start with
+a dot character.
+
+You can make glob treat dots as normal characters by setting
+`dot:true` in the options.
+
+### Basename Matching
+
+If you set `matchBase:true` in the options, and the pattern has no
+slashes in it, then it will seek for any file anywhere in the tree
+with a matching basename.  For example, `*.js` would match
+`test/simple/basic.js`.
+
+### Empty Sets
+
+If no matching files are found, then an empty array is returned.  This
+differs from the shell, where the pattern itself is returned.  For
+example:
+
+    $ echo a*s*d*f
+    a*s*d*f
+
+To get the bash-style behavior, set the `nonull:true` in the options.
+
+### See Also:
+
+* `man sh`
+* `man bash` (Search for "Pattern Matching")
+* `man 3 fnmatch`
+* `man 5 gitignore`
+* [minimatch documentation](https://github.com/isaacs/minimatch)
+
+## glob.hasMagic(pattern, [options])
+
+Returns `true` if there are any special characters in the pattern, and
+`false` otherwise.
+
+Note that the options affect the results.  If `noext:true` is set in
+the options object, then `+(a|b)` will not be considered a magic
+pattern.  If the pattern has a brace expansion, like `a/{b/c,x/y}`
+then that is considered magical, unless `nobrace:true` is set in the
+options.
+
+## glob(pattern, [options], cb)
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* `cb` `{Function}`
+  * `err` `{Error | null}`
+  * `matches` `{Array}` filenames found matching the pattern
+
+Perform an asynchronous glob search.
+
+## glob.sync(pattern, [options])
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* return: `{Array}` filenames found matching the pattern
+
+Perform a synchronous glob search.
+
+## Class: glob.Glob
+
+Create a Glob object by instantiating the `glob.Glob` class.
+
+```javascript
+var Glob = require("glob").Glob
+var mg = new Glob(pattern, options, cb)
+```
+
+It's an EventEmitter, and starts walking the filesystem to find matches
+immediately.
+
+### new glob.Glob(pattern, [options], [cb])
+
+* `pattern` `{String}` pattern to search for
+* `options` `{Object}`
+* `cb` `{Function}` Called when an error occurs, or matches are found
+  * `err` `{Error | null}`
+  * `matches` `{Array}` filenames found matching the pattern
+
+Note that if the `sync` flag is set in the options, then matches will
+be immediately available on the `g.found` member.
+
+### Properties
+
+* `minimatch` The minimatch object that the glob uses.
+* `options` The options object passed in.
+* `aborted` Boolean which is set to true when calling `abort()`.  There
+  is no way at this time to continue a glob search after aborting, but
+  you can re-use the statCache to avoid having to duplicate syscalls.
+* `cache` Convenience object.  Each field has the following possible
+  values:
+  * `false` - Path does not exist
+  * `true` - Path exists
+  * `'FILE'` - Path exists, and is not a directory
+  * `'DIR'` - Path exists, and is a directory
+  * `[file, entries, ...]` - Path exists, is a directory, and the
+    array value is the results of `fs.readdir`
+* `statCache` Cache of `fs.stat` results, to prevent statting the same
+  path multiple times.
+* `symlinks` A record of which paths are symbolic links, which is
+  relevant in resolving `**` patterns.
+* `realpathCache` An optional object which is passed to `fs.realpath`
+  to minimize unnecessary syscalls.  It is stored on the instantiated
+  Glob object, and may be re-used.
+
+### Events
+
+* `end` When the matching is finished, this is emitted with all the
+  matches found.  If the `nonull` option is set, and no match was found,
+  then the `matches` list contains the original pattern.  The matches
+  are sorted, unless the `nosort` flag is set.
+* `match` Every time a match is found, this is emitted with the specific
+  thing that matched. It is not deduplicated or resolved to a realpath.
+* `error` Emitted when an unexpected error is encountered, or whenever
+  any fs error occurs if `options.strict` is set.
+* `abort` When `abort()` is called, this event is raised.
+
+### Methods
+
+* `pause` Temporarily stop the search
+* `resume` Resume the search
+* `abort` Stop the search forever
+
+### Options
+
+All the options that can be passed to Minimatch can also be passed to
+Glob to change pattern matching behavior.  Also, some have been added,
+or have glob-specific ramifications.
+
+All options are false by default, unless otherwise noted.
+
+All options are added to the Glob object, as well.
+
+If you are running many `glob` operations, you can pass a Glob object
+as the `options` argument to a subsequent operation to shortcut some
+`stat` and `readdir` calls.  At the very least, you may pass in shared
+`symlinks`, `statCache`, `realpathCache`, and `cache` options, so that
+parallel glob operations will be sped up by sharing information about
+the filesystem.
+
+* `cwd` The current working directory in which to search.  Defaults
+  to `process.cwd()`.
+* `root` The place where patterns starting with `/` will be mounted
+  onto.  Defaults to `path.resolve(options.cwd, "/")` (`/` on Unix
+  systems, and `C:\` or some such on Windows.)
+* `dot` Include `.dot` files in normal matches and `globstar` matches.
+  Note that an explicit dot in a portion of the pattern will always
+  match dot files.
+* `nomount` By default, a pattern starting with a forward-slash will be
+  "mounted" onto the root setting, so that a valid filesystem path is
+  returned.  Set this flag to disable that behavior.
+* `mark` Add a `/` character to directory matches.  Note that this
+  requires additional stat calls.
+* `nosort` Don't sort the results.
+* `stat` Set to true to stat *all* results.  This reduces performance
+  somewhat, and is completely unnecessary, unless `readdir` is presumed
+  to be an untrustworthy indicator of file existence.
+* `silent` When an unusual error is encountered when attempting to
+  read a directory, a warning will be printed to stderr.  Set the
+  `silent` option to true to suppress these warnings.
+* `strict` When an unusual error is encountered when attempting to
+  read a directory, the process will just continue on in search of
+  other matches.  Set the `strict` option to raise an error in these
+  cases.
+* `cache` See `cache` property above.  Pass in a previously generated
+  cache object to save some fs calls.
+* `statCache` A cache of results of filesystem information, to prevent
+  unnecessary stat calls.  While it should not normally be necessary
+  to set this, you may pass the statCache from one glob() call to the
+  options object of another, if you know that the filesystem will not
+  change between calls.  (See "Race Conditions" below.)
+* `symlinks` A cache of known symbolic links.  You may pass in a
+  previously generated `symlinks` object to save `lstat` calls when
+  resolving `**` matches.
+* `sync` DEPRECATED: use `glob.sync(pattern, opts)` instead.
+* `nounique` In some cases, brace-expanded patterns can result in the
+  same file showing up multiple times in the result set.  By default,
+  this implementation prevents duplicates in the result set.  Set this
+  flag to disable that behavior.
+* `nonull` Set to never return an empty set, instead returning a set
+  containing the pattern itself.  This is the default in glob(3).
+* `debug` Set to enable debug logging in minimatch and glob.
+* `nobrace` Do not expand `{a,b}` and `{1..3}` brace sets.
+* `noglobstar` Do not match `**` against multiple filenames.  (Ie,
+  treat it as a normal `*` instead.)
+* `noext` Do not match `+(a|b)` "extglob" patterns.
+* `nocase` Perform a case-insensitive match.  Note: on
+  case-insensitive filesystems, non-magic patterns will match by
+  default, since `stat` and `readdir` will not raise errors.
+* `matchBase` Perform a basename-only match if the pattern does not
+  contain any slash characters.  That is, `*.js` would be treated as
+  equivalent to `**/*.js`, matching all js files in all directories.
+* `nodir` Do not match directories, only files.  (Note: to match
+  *only* directories, simply put a `/` at the end of the pattern.)
+* `ignore` Add a pattern or an array of glob patterns to exclude matches.
+  Note: `ignore` patterns are *always* in `dot:true` mode, regardless
+  of any other settings.
+* `follow` Follow symlinked directories when expanding `**` patterns.
+  Note that this can result in a lot of duplicate references in the
+  presence of cyclic links.
+* `realpath` Set to true to call `fs.realpath` on all of the results.
+  In the case of a symlink that cannot be resolved, the full absolute
+  path to the matched entry is returned (though it will usually be a
+  broken symlink)
+* `absolute` Set to true to always receive absolute paths for matched
+  files.  Unlike `realpath`, this also affects the values returned in
+  the `match` event.
+
+## Comparisons to other fnmatch/glob implementations
+
+While strict compliance with the existing standards is a worthwhile
+goal, some discrepancies exist between node-glob and other
+implementations, and are intentional.
+
+The double-star character `**` is supported by default, unless the
+`noglobstar` flag is set.  This is supported in the manner of bsdglob
+and bash 4.3, where `**` only has special significance if it is the only
+thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
+`a/**b` will not.
+
+Note that symlinked directories are not crawled as part of a `**`,
+though their contents may match against subsequent portions of the
+pattern.  This prevents infinite loops and duplicates and the like.
+
+If an escaped pattern has no matches, and the `nonull` flag is set,
+then glob returns the pattern as-provided, rather than
+interpreting the character escapes.  For example,
+`glob.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
+`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
+that it does not resolve escaped pattern characters.
+
+If brace expansion is not disabled, then it is performed before any
+other interpretation of the glob pattern.  Thus, a pattern like
+`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
+**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
+checked for validity.  Since those two are valid, matching proceeds.
+
+### Comments and Negation
+
+Previously, this module let you mark a pattern as a "comment" if it
+started with a `#` character, or a "negated" pattern if it started
+with a `!` character.
+
+These options were deprecated in version 5, and removed in version 6.
+
+To specify things that should not match, use the `ignore` option.
+
+## Windows
+
+**Please only use forward-slashes in glob expressions.**
+
+Though windows uses either `/` or `\` as its path separator, only `/`
+characters are used by this glob implementation.  You must use
+forward-slashes **only** in glob expressions.  Back-slashes will always
+be interpreted as escape characters, not path separators.
+
+Results from absolute patterns such as `/foo/*` are mounted onto the
+root setting using `path.join`.  On windows, this will by default result
+in `/foo/*` matching `C:\foo\bar.txt`.
+
+## Race Conditions
+
+Glob searching, by its very nature, is susceptible to race conditions,
+since it relies on directory walking and such.
+
+As a result, it is possible that a file that exists when glob looks for
+it may have been deleted or modified by the time it returns the result.
+
+As part of its internal implementation, this program caches all stat
+and readdir calls that it makes, in order to cut down on system
+overhead.  However, this also makes it even more susceptible to races,
+especially if the cache or statCache objects are reused between glob
+calls.
+
+Users are thus advised not to use a glob result as a guarantee of
+filesystem state in the face of rapid changes.  For the vast majority
+of operations, this is never a problem.
+

+# Growl for nodejs
+[![Build Status](https://travis-ci.org/tj/node-growl.svg?branch=master)](https://travis-ci.org/tj/node-growl)
+
+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).
+
+## Installation
+
+### Install
+
+### Mac OS X (Darwin):
+
+  Install [growlnotify(1)](http://growl.info/extras.php#growlnotify). On OS X 10.8, Notification Center is supported using [terminal-notifier](https://github.com/alloy/terminal-notifier). To install:
+
+    $ sudo gem install terminal-notifier
+
+  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
+
+```javascript
+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
+  - exec
+    - manually specify a shell command instead
+      - appends message to end of shell command
+      - or, replaces `%s` with message
+      - optionally prepends title (example: `title: message`)
+      - examples: `{exec: 'tmux display-message'}`, `{exec: 'echo "%s" > messages.log}`

+_he_ (for “HTML entities”) is a robust HTML entity encoder/decoder written in JavaScript. It supports [all standardized named character references as per HTML](https://html.spec.whatwg.org/multipage/syntax.html#named-character-references), handles [ambiguous ampersands](https://mathiasbynens.be/notes/ambiguous-ampersands) and other edge cases [just like a browser would](https://html.spec.whatwg.org/multipage/syntax.html#tokenizing-character-references), has an extensive test suite, and — contrary to many other JavaScript solutions — _he_ handles astral Unicode symbols just fine.

+A string representing the semantic version number.
+
+### `he.encode(text, options)`
+
+This function takes a string of text and encodes (by default) any symbols that aren’t printable ASCII symbols and `&`, `<`, `>`, `"`, `'`, and `` ` ``, replacing them with character references.
+
+```js
+he.encode('foo © bar ≠ baz 𝌆 qux');
+// → 'foo © bar ≠ baz 𝌆 qux'
+```
+
+As long as the input string contains [allowed code points](https://html.spec.whatwg.org/multipage/parsing.html#preprocessing-the-input-stream) only, the return value of this function is always valid HTML. Any [(invalid) code points that cannot be represented using a character reference](https://html.spec.whatwg.org/multipage/syntax.html#table-charref-overrides) in the input are not encoded:
+
+```js
+he.encode('foo \0 bar');
+// → 'foo \0 bar'
+```
+
+However, enabling [the `strict` option](https://github.com/mathiasbynens/he#strict) causes invalid code points to throw an exception. With `strict` enabled, `he.encode` either throws (if the input contains invalid code points) or returns a string of valid HTML.
+
+The `options` object is optional. It recognizes the following properties:
+
+#### `useNamedReferences`
+
+The default value for the `useNamedReferences` option is `false`. This means that `encode()` will not use any named character references (e.g. `©`) in the output — hexadecimal escapes (e.g. `©`) will be used instead. Set it to `true` to enable the use of named references.
+
+**Note that if compatibility with older browsers is a concern, this option should remain disabled.**
+
+```js
+// Using the global default setting (defaults to `false`):
+he.encode('foo © bar ≠ baz 𝌆 qux');
+// → 'foo © bar ≠ baz 𝌆 qux'
+
+// Passing an `options` object to `encode`, to explicitly disallow named references:
+he.encode('foo © bar ≠ baz 𝌆 qux', {
+  'useNamedReferences': false
+});
+// → 'foo © bar ≠ baz 𝌆 qux'
+
+// Passing an `options` object to `encode`, to explicitly allow named references:
+he.encode('foo © bar ≠ baz 𝌆 qux', {
+  'useNamedReferences': true
+});
+// → 'foo © bar ≠ baz 𝌆 qux'
+```
+
+#### `decimal`
+
+The default value for the `decimal` option is `false`. If the option is enabled, `encode` will generally use decimal escapes (e.g. `©`) rather than hexadecimal escapes (e.g. `©`). Beside of this replacement, the basic behavior remains the same when combined with other options. For example: if both options `useNamedReferences` and `decimal` are enabled, named references (e.g. `©`) are used over decimal escapes. HTML entities without a named reference are encoded using decimal escapes.
+
+```js
+// Using the global default setting (defaults to `false`):
+he.encode('foo © bar ≠ baz 𝌆 qux');
+// → 'foo © bar ≠ baz 𝌆 qux'
+
+// Passing an `options` object to `encode`, to explicitly disable decimal escapes:
+he.encode('foo © bar ≠ baz 𝌆 qux', {
+  'decimal': false
+});
+// → 'foo © bar ≠ baz 𝌆 qux'
+
+// Passing an `options` object to `encode`, to explicitly enable decimal escapes:
+he.encode('foo © bar ≠ baz 𝌆 qux', {
+  'decimal': true
+});
+// → 'foo © bar ≠ baz 𝌆 qux'
+
+// Passing an `options` object to `encode`, to explicitly allow named references and decimal escapes:
+he.encode('foo © bar ≠ baz 𝌆 qux', {
+  'useNamedReferences': true,
+  'decimal': true
+});
+// → 'foo © bar ≠ baz 𝌆 qux'
+```
+
+#### `encodeEverything`
+
+The default value for the `encodeEverything` option is `false`. This means that `encode()` will not use any character references for printable ASCII symbols that don’t need escaping. Set it to `true` to encode every symbol in the input string. When set to `true`, this option takes precedence over `allowUnsafeSymbols` (i.e. setting the latter to `true` in such a case has no effect).
+
+```js
+// Using the global default setting (defaults to `false`):
+he.encode('foo © bar ≠ baz 𝌆 qux');
+// → 'foo © bar ≠ baz 𝌆 qux'
+
+// Passing an `options` object to `encode`, to explicitly encode all symbols:
+he.encode('foo © bar ≠ baz 𝌆 qux', {
+  'encodeEverything': true
+});
+// → 'foo © bar ≠ baz 𝌆 qux'
+
+// This setting can be combined with the `useNamedReferences` option:
+he.encode('foo © bar ≠ baz 𝌆 qux', {
+  'encodeEverything': true,
+  'useNamedReferences': true
+});
+// → 'foo © bar ≠ baz 𝌆 qux'
+```
+
+#### `strict`
+
+The default value for the `strict` option is `false`. This means that `encode()` will encode any HTML text content you feed it, even if it contains any symbols that cause [parse errors](https://html.spec.whatwg.org/multipage/parsing.html#preprocessing-the-input-stream). To throw an error when such invalid HTML is encountered, set the `strict` option to `true`. This option makes it possible to use _he_ as part of HTML parsers and HTML validators.
+
+```js
+// Using the global default setting (defaults to `false`, i.e. error-tolerant mode):
+he.encode('\x01');
+// → ''
+
+// Passing an `options` object to `encode`, to explicitly enable error-tolerant mode:
+he.encode('\x01', {
+  'strict': false
+});
+// → ''
+
+// Passing an `options` object to `encode`, to explicitly enable strict mode:
+he.encode('\x01', {
+  'strict': true
+});
+// → Parse error
+```
+
+#### `allowUnsafeSymbols`
+
+The default value for the `allowUnsafeSymbols` option is `false`. This means that characters that are unsafe for use in HTML content (`&`, `<`, `>`, `"`, `'`, and `` ` ``) will be encoded. When set to `true`, only non-ASCII characters will be encoded. If the `encodeEverything` option is set to `true`, this option will be ignored.
+
+```js
+he.encode('foo © and & ampersand', {
+  'allowUnsafeSymbols': true
+});
+// → 'foo © and & ampersand'
+```
+
+#### Overriding default `encode` options globally
+
+The global default setting can be overridden by modifying the `he.encode.options` object. This saves you from passing in an `options` object for every call to `encode` if you want to use the non-default setting.
+
+```js
+// Read the global default setting:
+he.encode.options.useNamedReferences;
+// → `false` by default
+
+// Override the global default setting:
+he.encode.options.useNamedReferences = true;
+
+// Using the global default setting, which is now `true`:
+he.encode('foo © bar ≠ baz 𝌆 qux');
+// → 'foo © bar ≠ baz 𝌆 qux'
+```
+
+### `he.decode(html, options)`
+
+This function takes a string of HTML and decodes any named and numerical character references in it using [the algorithm described in section 12.2.4.69 of the HTML spec](https://html.spec.whatwg.org/multipage/syntax.html#tokenizing-character-references).
+
+```js
+he.decode('foo © bar ≠ baz 𝌆 qux');
+// → 'foo © bar ≠ baz 𝌆 qux'
+```
+
+The `options` object is optional. It recognizes the following properties:
+
+#### `isAttributeValue`
+
+The default value for the `isAttributeValue` option is `false`. This means that `decode()` will decode the string as if it were used in [a text context in an HTML document](https://html.spec.whatwg.org/multipage/syntax.html#data-state). HTML has different rules for [parsing character references in attribute values](https://html.spec.whatwg.org/multipage/syntax.html#character-reference-in-attribute-value-state) — set this option to `true` to treat the input string as if it were used as an attribute value.
+
+```js
+// Using the global default setting (defaults to `false`, i.e. HTML text context):
+he.decode('foo&bar');
+// → 'foo&bar'
+
+// Passing an `options` object to `decode`, to explicitly assume an HTML text context:
+he.decode('foo&bar', {
+  'isAttributeValue': false
+});
+// → 'foo&bar'
+
+// Passing an `options` object to `decode`, to explicitly assume an HTML attribute value context:
+he.decode('foo&bar', {
+  'isAttributeValue': true
+});
+// → 'foo&bar'
+```
+
+#### `strict`
+
+The default value for the `strict` option is `false`. This means that `decode()` will decode any HTML text content you feed it, even if it contains any entities that cause [parse errors](https://html.spec.whatwg.org/multipage/syntax.html#tokenizing-character-references). To throw an error when such invalid HTML is encountered, set the `strict` option to `true`. This option makes it possible to use _he_ as part of HTML parsers and HTML validators.
+
+```js
+// Using the global default setting (defaults to `false`, i.e. error-tolerant mode):
+he.decode('foo&bar');
+// → 'foo&bar'
+
+// Passing an `options` object to `decode`, to explicitly enable error-tolerant mode:
+he.decode('foo&bar', {
+  'strict': false
+});
+// → 'foo&bar'
+
+// Passing an `options` object to `decode`, to explicitly enable strict mode:
+he.decode('foo&bar', {
+  'strict': true
+});
+// → Parse error
+```
+
+#### Overriding default `decode` options globally
+
+The global default settings for the `decode` function can be overridden by modifying the `he.decode.options` object. This saves you from passing in an `options` object for every call to `decode` if you want to use a non-default setting.
+
+```js
+// Read the global default setting:
+he.decode.options.isAttributeValue;
+// → `false` by default
+
+// Override the global default setting:
+he.decode.options.isAttributeValue = true;
+
+// Using the global default setting, which is now `true`:
+he.decode('foo&bar');
+// → 'foo&bar'
+```
+
+### `he.escape(text)`
+
+This function takes a string of text and escapes it for use in text contexts in XML or HTML documents. Only the following characters are escaped: `&`, `<`, `>`, `"`, `'`, and `` ` ``.
+
+```js
+he.escape('');
+// → '<img src='x' onerror="prompt(1)">'
+```
+
+### `he.unescape(html, options)`
+
+`he.unescape` is an alias for `he.decode`. It takes a string of HTML and decodes any named and numerical character references in it.
+
+### Using the `he` binary
+
+To use the `he` binary in your shell, simply install _he_ globally using npm:
+
+```bash
+npm install -g he
+```
+
+After that you will be able to encode/decode HTML entities from the command line:
+
+```bash
+$ he --encode 'föo ♥ bår 𝌆 baz'
+föo ♥ bår 𝌆 baz
+
+$ he --encode --use-named-refs 'föo ♥ bår 𝌆 baz'
+föo ♥ bår 𝌆 baz
+
+$ he --decode 'föo ♥ bår 𝌆 baz'
+föo ♥ bår 𝌆 baz
+```
+
+Read a local text file, encode it for use in an HTML text context, and save the result to a new file:
+
+```bash
+$ he --encode < foo.txt > foo-escaped.html
+```
+
+Or do the same with an online text file:
+
+```bash
+$ curl -sL "http://git.io/HnfEaw" | he --encode > escaped.html
+```
+
+Or, the opposite — read a local file containing a snippet of HTML in a text context, decode it back to plain text, and save the result to a new file:
+
+```bash
+$ he --decode < foo-escaped.html > foo.txt
+```
+
+Or do the same with an online HTML snippet:
+
+```bash
+$ curl -sL "http://git.io/HnfEaw" | he --decode > decoded.txt
+```
+
+See `he --help` for the full list of options.

+.Sh DESCRIPTION
+.Nm
+encodes/decodes HTML entities in strings just like a browser would.
+.Sh OPTIONS
+.Bl -ohang -offset
+.It Sy "--escape"
+Take a string of text and escape it for use in text contexts in XML or HTML documents. Only the following characters are escaped: `&`, `<`, `>`, `"`, and `'`.
+.It Sy "--encode"
+Take a string of text and encode any symbols that aren't printable ASCII symbols and that can be replaced with character references. For example, it would turn `©` into `©`, but it wouldn't turn `+` into `+` since there is no point in doing so. Additionally, it replaces any remaining non-ASCII symbols with a hexadecimal escape sequence (e.g. `𝌆`). The return value of this function is always valid HTML.
+.It Sy "--encode --use-named-refs"
+Enable the use of named character references (like `©`) in the output. If compatibility with older browsers is a concern, don't use this option.
+.It Sy "--encode --everything"
+Encode every symbol in the input string, even safe printable ASCII symbols.
+.It Sy "--encode --allow-unsafe"
+Encode non-ASCII characters only. This leaves unsafe HTML/XML symbols like `&`, `<`, `>`, `"`, and `'` intact.
+.It Sy "--encode --decimal"
+Use decimal digits rather than hexadecimal digits for encoded character references, e.g. output `©` instead of `©`.
+.It Sy "--decode"
+Takes a string of HTML and decode any named and numerical character references in it using the algorithm described in the HTML spec.
+.It Sy "--decode --attribute"
+Parse the input as if it was an HTML attribute value rather than a string in an HTML text content.
+.It Sy "--decode --strict"
+Throw an error if an invalid character reference is encountered.
+.It Sy "-v, --version"
+Print he's version.
+.It Sy "-h, --help"
+Show the help screen.
+.El
+.Sh EXIT STATUS
+The
+.Nm he
+utility exits with one of the following values:
+.Pp
+.Bl -tag -width flag -compact
+.It Li 0
+.Nm
+did what it was instructed to do successfully; either it encoded/decoded the input and printed the result, or it printed the version or usage message.
+.It Li 1
+.Nm
+encountered an error.
+.El
+.Sh EXAMPLES
+.Bl -ohang -offset
+.It Sy "he --escape ''"
+Print an escaped version of the given string that is safe for use in HTML text contexts, escaping only `&`, `<`, `>`, `"`, and `'`.
+.It Sy "he --decode '©𝌆'"
+Print the decoded version of the given HTML string.
+.It Sy "echo\ '©𝌆'\ |\ he --decode"
+Print the decoded version of the HTML string that gets piped in.

+# inflight
+
+Add callbacks to requests in flight to avoid async duplication
+
+## USAGE
+
+```javascript
+var inflight = require('inflight')
+
+// some request that does some stuff
+function req(key, callback) {
+  // key is any random string.  like a url or filename or whatever.
+  //
+  // will return either a falsey value, indicating that the
+  // request for this key is already in flight, or a new callback
+  // which when called will call all callbacks passed to inflightk
+  // with the same key
+  callback = inflight(key, callback)
+
+  // If we got a falsey value back, then there's already a req going
+  if (!callback) return
+
+  // this is where you'd fetch the url or whatever
+  // callback is also once()-ified, so it can safely be assigned
+  // to multiple events etc.  First call wins.
+  setTimeout(function() {
+    callback(null, key)
+  }, 100)
+}
+
+// only assigns a single setTimeout
+// when it dings, all cbs get called
+req('foo', cb1)
+req('foo', cb2)
+req('foo', cb3)
+req('foo', cb4)

+Browser-friendly inheritance fully compatible with standard node.js
+[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
+
+This package exports standard `inherits` from node.js `util` module in
+node environment, but also provides alternative browser-friendly
+implementation through [browser
+field](https://gist.github.com/shtylman/4339901). Alternative
+implementation is a literal copy of standard one located in standalone
+module to avoid requiring of `util`. It also has a shim for old
+browsers with no `Object.create` support.
+
+While keeping you sure you are using standard `inherits`
+implementation in node.js environment, it allows bundlers such as
+[browserify](https://github.com/substack/node-browserify) to not
+include full `util` package to your client code if all you need is
+just `inherits` function. It worth, because browser shim for `util`
+package is large and `inherits` is often the single function you need
+from it.
+
+It's recommended to use this package instead of
+`require('util').inherits` for any code that has chances to be used
+not only in node.js but in browser too.
+
+## usage
+
+```js
+var inherits = require('inherits');
+// then use exactly as the standard one
+```
+
+## note on version ~1.0
+
+Version ~1.0 had completely different motivation and is not compatible
+neither with 2.0 nor with standard node.js `inherits`.
+
+If you are using version ~1.0 and planning to switch to ~2.0, be
+careful:
+
+* new version uses `super_` instead of `super` for referencing
+  superclass
+* new version overwrites current prototype while old one preserves any
+  existing fields on it

+# minimatch
+
+A minimal matching utility.
+
+[![Build Status](https://secure.travis-ci.org/isaacs/minimatch.svg)](http://travis-ci.org/isaacs/minimatch)
+
+
+This is the matching library used internally by npm.
+
+It works by converting glob expressions into JavaScript `RegExp`
+objects.
+
+## Usage
+
+```javascript
+var minimatch = require("minimatch")
+
+minimatch("bar.foo", "*.foo") // true!
+minimatch("bar.foo", "*.bar") // false!
+minimatch("bar.foo", "*.+(bar|foo)", { debug: true }) // true, and noisy!
+```
+
+## Features
+
+Supports these glob features:
+
+* Brace Expansion
+* Extended glob matching
+* "Globstar" `**` matching
+
+See:
+
+* `man sh`
+* `man bash`
+* `man 3 fnmatch`
+* `man 5 gitignore`
+
+## Minimatch Class
+
+Create a minimatch object by instantiating the `minimatch.Minimatch` class.
+
+```javascript
+var Minimatch = require("minimatch").Minimatch
+var mm = new Minimatch(pattern, options)
+```
+
+### Properties
+
+* `pattern` The original pattern the minimatch object represents.
+* `options` The options supplied to the constructor.
+* `set` A 2-dimensional array of regexp or string expressions.
+  Each row in the
+  array corresponds to a brace-expanded pattern.  Each item in the row
+  corresponds to a single path-part.  For example, the pattern
+  `{a,b/c}/d` would expand to a set of patterns like:
+
+        [ [ a, d ]
+        , [ b, c, d ] ]
+
+    If a portion of the pattern doesn't have any "magic" in it
+    (that is, it's something like `"foo"` rather than `fo*o?`), then it
+    will be left as a string rather than converted to a regular
+    expression.
+
+* `regexp` Created by the `makeRe` method.  A single regular expression
+  expressing the entire pattern.  This is useful in cases where you wish
+  to use the pattern somewhat like `fnmatch(3)` with `FNM_PATH` enabled.
+* `negate` True if the pattern is negated.
+* `comment` True if the pattern is a comment.
+* `empty` True if the pattern is `""`.
+
+### Methods
+
+* `makeRe` Generate the `regexp` member if necessary, and return it.
+  Will return `false` if the pattern is invalid.
+* `match(fname)` Return true if the filename matches the pattern, or
+  false otherwise.
+* `matchOne(fileArray, patternArray, partial)` Take a `/`-split
+  filename, and match it against a single row in the `regExpSet`.  This
+  method is mainly for internal use, but is exposed so that it can be
+  used by a glob-walker that needs to avoid excessive filesystem calls.
+
+All other methods are internal, and will be called as necessary.
+
+### minimatch(path, pattern, options)
+
+Main export.  Tests a path against the pattern using the options.
+
+```javascript
+var isJS = minimatch(file, "*.js", { matchBase: true })
+```
+
+### minimatch.filter(pattern, options)
+
+Returns a function that tests its
+supplied argument, suitable for use with `Array.filter`.  Example:
+
+```javascript
+var javascripts = fileList.filter(minimatch.filter("*.js", {matchBase: true}))
+```
+
+### minimatch.match(list, pattern, options)
+
+Match against the list of
+files, in the style of fnmatch or glob.  If nothing is matched, and
+options.nonull is set, then return a list containing the pattern itself.
+
+```javascript
+var javascripts = minimatch.match(fileList, "*.js", {matchBase: true}))
+```
+
+### minimatch.makeRe(pattern, options)
+
+Make a regular expression object from the pattern.
+
+## Options
+
+All options are `false` by default.
+
+### debug
+
+Dump a ton of stuff to stderr.
+
+### nobrace
+
+Do not expand `{a,b}` and `{1..3}` brace sets.
+
+### noglobstar
+
+Disable `**` matching against multiple folder names.
+
+### dot
+
+Allow patterns to match filenames starting with a period, even if
+the pattern does not explicitly have a period in that spot.
+
+Note that by default, `a/**/b` will **not** match `a/.d/b`, unless `dot`
+is set.
+
+### noext
+
+Disable "extglob" style patterns like `+(a|b)`.
+
+### nocase
+
+Perform a case-insensitive match.
+
+### nonull
+
+When a match is not found by `minimatch.match`, return a list containing
+the pattern itself if this option is set.  When not set, an empty list
+is returned if there are no matches.
+
+### matchBase
+
+If set, then patterns without slashes will be matched
+against the basename of the path if it contains slashes.  For example,
+`a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`.
+
+### nocomment
+
+Suppress the behavior of treating `#` at the start of a pattern as a
+comment.
+
+### nonegate
+
+Suppress the behavior of treating a leading `!` character as negation.
+
+### flipNegate
+
+Returns from negate expressions the same as if they were not negated.
+(Ie, true on a hit, false on a miss.)
+
+
+## Comparisons to other fnmatch/glob implementations
+
+While strict compliance with the existing standards is a worthwhile
+goal, some discrepancies exist between minimatch and other
+implementations, and are intentional.
+
+If the pattern starts with a `!` character, then it is negated.  Set the
+`nonegate` flag to suppress this behavior, and treat leading `!`
+characters normally.  This is perhaps relevant if you wish to start the
+pattern with a negative extglob pattern like `!(a|B)`.  Multiple `!`
+characters at the start of a pattern will negate the pattern multiple
+times.
+
+If a pattern starts with `#`, then it is treated as a comment, and
+will not match anything.  Use `\#` to match a literal `#` at the
+start of a line, or set the `nocomment` flag to suppress this behavior.
+
+The double-star character `**` is supported by default, unless the
+`noglobstar` flag is set.  This is supported in the manner of bsdglob
+and bash 4.1, where `**` only has special significance if it is the only
+thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
+`a/**b` will not.
+
+If an escaped pattern has no matches, and the `nonull` flag is set,
+then minimatch.match returns the pattern as-provided, rather than
+interpreting the character escapes.  For example,
+`minimatch.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
+`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
+that it does not resolve escaped pattern characters.
+
+If brace expansion is not disabled, then it is performed before any
+other interpretation of the glob pattern.  Thus, a pattern like
+`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
+**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
+checked for validity.  Since those two are valid, matching proceeds.

+# minimist
+
+parse argument options
+
+This module is the guts of optimist's argument parser without all the
+fanciful decoration.
+
+[![browser support](https://ci.testling.com/substack/minimist.png)](http://ci.testling.com/substack/minimist)
+
+[![build status](https://secure.travis-ci.org/substack/minimist.png)](http://travis-ci.org/substack/minimist)
+
+# example
+
+``` js
+var argv = require('minimist')(process.argv.slice(2));
+console.dir(argv);
+```
+
+```
+$ node example/parse.js -a beep -b boop
+{ _: [], a: 'beep', b: 'boop' }
+```
+
+```
+$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
+{ _: [ 'foo', 'bar', 'baz' ],
+  x: 3,
+  y: 4,
+  n: 5,
+  a: true,
+  b: true,
+  c: true,
+  beep: 'boop' }
+```
+
+# methods
+
+``` js
+var parseArgs = require('minimist')
+```
+
+## var argv = parseArgs(args, opts={})
+
+Return an argument object `argv` populated with the array arguments from `args`.
+
+`argv._` contains all the arguments that didn't have an option associated with
+them.
+
+Numeric-looking arguments will be returned as numbers unless `opts.string` or
+`opts.boolean` is set for that argument name.
+
+Any arguments after `'--'` will not be parsed and will end up in `argv._`.
+
+options can be:
+
+* `opts.string` - a string or array of strings argument names to always treat as
+strings
+* `opts.boolean` - a string or array of strings to always treat as booleans
+* `opts.alias` - an object mapping string names to strings or arrays of string
+argument names to use as aliases
+* `opts.default` - an object mapping string argument names to default values

+# 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
+
+```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
+
+```js
+var mkdirp = require('mkdirp');
+```
+
+## mkdirp(dir, opts, cb)
+
+Create a new directory and any necessary subdirectories at `dir` with octal
+permission string `opts.mode`. If `opts` is a non-object, it will be treated as
+the `opts.mode`.
+
+If `opts.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.
+
+You can optionally pass in an alternate `fs` implementation by passing in
+`opts.fs`. Your implementation should have `opts.fs.mkdir(path, mode, cb)` and
+`opts.fs.stat(path, cb)`.
+
+## mkdirp.sync(dir, opts)
+
+Synchronously create a new directory and any necessary subdirectories at `dir`
+with octal permission string `opts.mode`. If `opts` is a non-object, it will be
+treated as the `opts.mode`.
+
+If `opts.mode` isn't specified, it defaults to `0777 & (~process.umask())`.
+
+Returns the first directory that had to be created, if any.
+
+You can optionally pass in an alternate `fs` implementation by passing in
+`opts.fs`. Your implementation should have `opts.fs.mkdirSync(path, mode)` and
+`opts.fs.statSync(path)`.
+
+# usage
+
+This package also ships with a `mkdirp` command.
+
+```
+usage: mkdirp [DIR1,DIR2..] {OPTIONS}
+
+  Create each supplied directory including any necessary parent directories that
+  don't yet exist.
+  
+  If the directory already exists, do nothing.
+
+OPTIONS are:
+
+  -m, --mode   If a directory needs to be created, set the mode as an octal
+               permission string.
+
+```
+
+# install
+
+With [npm](http://npmjs.org) do:
+
+```
+npm install mkdirp
+```
+
+to get the library, or
+
+```
+npm install -g mkdirp
+```
+
+to get the command.

+# 4.0.1 / 2017-10-05
+
+## :bug: Fixes
+
+- [#3051]: Upgrade Growl to v1.10.3 to fix its [peer dep problems](https://github.com/tj/node-growl/pull/68) ([@dpogue])
+
+[#3051]: https://github.com/mochajs/mocha/pull/3051
+[@dpogue]: https://github.com/dpogue
+
+# 4.0.0 / 2017-10-02
+
+You might want to read this before filing a new bug!  :stuck_out_tongue_closed_eyes:
+
+## :boom: Breaking Changes
+
+For more info, please [read this article](https://boneskull.com/mocha-v4-nears-release/).
+
+### Compatibility
+
+- [#3016]: Drop support for unmaintained versions of Node.js ([@boneskull]):
+  - 0.10.x
+  - 0.11.x
+  - 0.12.x
+  - iojs (any)
+  - 5.x.x
+- [#2979]: Drop support for non-ES5-compliant browsers ([@boneskull]):
+  - IE7
+  - IE8
+  - PhantomJS 1.x
+- [#2615]: Drop Bower support; old versions (3.x, etc.) will remain available ([@ScottFreeCode], [@boneskull])
+
+### Default Behavior
+
+- [#2879]: By default, Mocha will no longer force the process to exit once all tests complete.  This means any test code (or code under test) which would normally prevent `node` from exiting will do so when run in Mocha.  Supply the `--exit` flag to revert to pre-v4.0.0 behavior ([@ScottFreeCode], [@boneskull])
+
+### Reporter Output
+
+- [#2095]: Remove `stdout:` prefix from browser reporter logs ([@skeggse])
+- [#2295]: Add separator in "unified diff" output ([@olsonpm])
+- [#2686]: Print failure message when `--forbid-pending` or `--forbid-only` is specified ([@ScottFreeCode])
+- [#2814]: Indent contexts for better readability when reporting failures ([@charlierudolph])
+
+## :-1: Deprecations
+
+- [#2493]: The `--compilers` command-line option is now soft-deprecated and will emit a warning on `STDERR`.  Read [this](https://github.com/mochajs/mocha/wiki/compilers-deprecation) for more info and workarounds ([@ScottFreeCode], [@boneskull])
+
+## :tada: Enhancements
+
+- [#2628]: Allow override of default test suite name in XUnit reporter ([@ngeor])
+
+## :book: Documentation
+
+- [#3020]: Link to CLA in `README.md` and `CONTRIBUTING.md` ([@skeggse])
+
+## :nut_and_bolt: Other
+
+- [#2890]: Speed up build by (re-)consolidating SauceLabs tests ([@boneskull])

+
+# 3.0.0 / 2016-07-31
+
+## :boom: Breaking Changes
+
+- :warning: Due to the increasing difficulty of applying security patches made within its dependency tree, as well as looming incompatibilities with Node.js v7.0, **Mocha no longer supports Node.js v0.8**.
+- :warning: **Mocha may no longer be installed by versions of `npm` less than `1.4.0`.**  Previously, this requirement only affected Mocha's development dependencies.  In short, this allows Mocha to depend on packages which have dependencies fixed to major versions (`^`).
+- `.only()` is no longer "fuzzy", can be used multiple times, and generally just works like you think it should. :joy:
+- To avoid common bugs, when a test injects a callback function (suggesting asynchronous execution), calls it, *and* returns a `Promise`, Mocha will now throw an exception:
+
+  ```js
+  const assert = require('assert');
+
+  it('should complete this test', function (done) {
+    return new Promise(function (resolve) {
+      assert.ok(true);
+      resolve();
+    })
+      .then(done);
+  });
+  ```
+
+  The above test will fail with `Error: Resolution method is overspecified. Specify a callback *or* return a Promise; not both.`.
+- When a test timeout value *greater than* `2147483648` is specified in any context (`--timeout`, `mocha.setup()`, per-suite, per-test, etc.), the timeout will be *disabled* and the test(s) will be allowed to run indefinitely.  This is equivalent to specifying a timeout value of `0`.  See [MDN](https://developer.mozilla.org/docs/Web/API/WindowTimers/setTimeout#Maximum_delay_value) for reasoning.
+- The `dot` reporter now uses more visually distinctive characters when indicating "pending" and "failed" tests.
+- Mocha no longer supports [component](https://www.npmjs.com/package/component).
+- The long-forsaken `HTMLCov` and `JSONCov` reporters--and any relationship to the "node-jscoverage" project--have been removed.
+- `spec` reporter now omits leading carriage returns (`\r`) in non-TTY environment.
+
+## :tada: Enhancements
+
+- [#808]: Allow regular-expression-like strings in `--grep` and browser's `grep` querystring; enables flags such as `i` for case-insensitive matches and `u` for unicode. ([@a8m])
+- [#2000]: Use distinctive characters in `dot` reporter; `,` will denote a "pending" test and `!` will denote a "failing" test. ([@elliottcable])
+- [#1632]: Throw a useful exception when a suite or test lacks a title. ([@a8m])
+- [#1481]: Better `.only()` behavior. ([@a8m])
+- [#2334]: Allow `this.skip()` in async tests and hooks. ([@boneskull])
+- [#1320]: Throw a useful exception when test resolution method is overspecified. ([@jugglinmike])
+- [#2364]: Support `--preserve-symlinks`. ([@rosswarren])
+
+## :bug: Bug Fixes
+
+- [#2259]: Restore ES3 compatibility.  Specifically, support an environment lacking `Date.prototype.toISOString()`, `JSON`, or has a non-standard implementation of `JSON`. ([@ndhoule], [@boneskull])
+- [#2286]: Fix `after()` failing to execute if test skipped using `this.skip()` in `beforeEach()`; no longer marks the entire suite as "pending". ([@dasilvacontin], [@boneskull])
+- [#2208]: Fix function name display in `markdown` and `html` (browser) reporters. ([@ScottFreeCode])
+- [#2299]: Fix progress bar in `html` (browser) reporter. ([@AviVahl])
+- [#2307]: Fix `doc` reporter crashing when test fails. ([@jleyba])
+- [#2323]: Ensure browser entry point (`browser-entry.js`) is published to npm (for use with bundlers).  ([@boneskull])
+- [#2310]: Ensure custom reporter with an absolute path works in Windows. ([@silentcloud])
+- [#2311]: Fix problem wherein calling `this.slow()` without a value would blast any previously set value. ([@boneskull])
+- [#1813]: Ensure Mocha's own test suite will run in Windows. ([@tswaters], [@TimothyGu], [@boneskull])
+- [#2317]: Ensure all interfaces are displayed in `--help` on CLI.  ([@ScottFreeCode])
+- [#1644]: Don't exhibit undefined behavior when calling `this.timeout()` with very large values ([@callumacrae], [@boneskull])
+- [#2361]: Don't truncate name of thrown anonymous exception. ([@boneskull])
+- [#2367]: Fix invalid CSS. ([@bensontrent])
+- [#2401]: Remove carriage return before each test line in spec reporter. ([@Munter])
+
+## :nut_and_bolt: Other
+
+- Upgrade production dependencies to address security advisories (and because now we can): `glob`, `commander`, `escape-string-regexp`,
+and `supports-color`. ([@boneskull], [@RobLoach])
+- Add Windows to CI. ([@boneskull], [@TimothyGu])
+- Ensure appropriate `engines` field in `package.json`. ([@shinnn], [@boneskull])

+
+# 2.5.0 / 2016-05-23
+
+> This has been awhile coming!  We needed to feel confident that the next release wouldn't break browser compatibility (e.g. the last few patch releases).
+>
+> ### Browser Tests in CI
+>
+> We now run unit tests against PhantomJS v1.x and an assortment of browsers on [SauceLabs](https://saucelabs.com), including:
+> - Internet Explorer v8.0
+> - Chrome (latest)
+> - Firefox (latest)
+> - Safari (latest)
+> - Microsoft Edge (latest)
+>
+> To accomplish this, we now run Mocha's unit tests (and a handful of integration tests) via [Karma](https://npmjs.com/package/karma) and a modified [karma-mocha](https://npmjs.com/package/karma-mocha).  Along the way, we had to solve issue [#880] (apologies to @mderijcke and @sukima who had PRs addressing this), as well as replace most usages of [should](https://npmjs.com/package/should) with [expect.js](https://npmjs.com/package/expect.js) for IE8.
+>
+> Going forward, when sending PRs, your code will *only* run against PhantomJS v1.x (and not hit SauceLabs) [because security](https://docs.travis-ci.com/user/pull-requests/#Security-Restrictions-when-testing-Pull-Requests).
+>
+> ### Node.js 6.x
+> Node.js 6.x "just worked" before, but now it's in the CI matrix, so it's "officially" supported.  Mocha *still retains support* for Node.js 0.8.x.
+>
+> ### "Minor" Release
+> You'll see mostly bug fixes below, but also a couple features--as such, it's a "minor" release.
+>
+> ### TYVM
+>
+> Thanks to everyone who contributed, and our fabulous [sponsors and backers](https://opencollective.com/mochajs)!

+# Mocha needs YOU!
+
+*Did you know* Mocha [is a dependency of over 100,000 projects](https://libraries.io/npm/mocha) published to npm alone?
+
+**Despite this, we're currently unable to merge most pull requests due to lack of maintenance resources.**
+
+**Are you interested in triaging issues or reviewing open PRs?  Have some time to hack on its codebase?**  If you would like to help maintain Mocha, please contact `@boneskull` on [Gitter](https://gitter.im/mochajs/mocha).
+
+*Thank you* :kissing_heart: to all of you interested in helping.  These are Mocha's immediate needs:
+
+1. Increase test coverage on Node.js and browser
+  - Increase integration coverage for all reporters
+    - `html` reporter must be tested in browser
+    - ~~Basic console reporters (*not* `nyan`, `landing`, etc.) must be tested in **both** browser and Node.js contexts; PhantomJS can consume all console reporters~~
+    - ~~Filesystem-based reporters must be tested in Node.js context~~
+    - **UPDATE - May 24 2017**: Thanks to [community contributions](https://github.com/mochajs/mocha/blob/master/CHANGELOG.md#mag-coverage), the coverage on most reporters has increased dramatically!  The `html` reporter is still in [dire need of coverage](https://coveralls.io/builds/11674428/source?filename=lib%2Freporters%2Fhtml.js).
+  - Increase coverage against all interfaces (`exports` in particular).  Ideally this becomes a "matrix" where we repeat sets of integration tests across all interfaces.
+  - Refactor non-Node.js-specific tests to allow them to run in a browser context.  Node.js-specific tests include those which *require* the CLI or filesystem.  Most everything else is fair game.
+2.  Review current open pull requests
+  - We need individuals familiar with Mocha's codebase. Got questions?  Ask them in [our chat room](https://gitter.im/mochajs/mocha).
+  - Pull requests **must** have supporting tests.  The only exceptions are pure cosmetic or non-functional changes.
+  - Pull request contributors must sign [the CLA](https://cla.js.foundation/mochajs/mocha).
+3. Close old, inactive issues and pull requests
+  - ~~A bot should do this.  We need a bot. Got a bot?~~ We now use GitHub's own [probot-stale](https://www.npmjs.com/package/probot-stale).
+4. Triage issues
+  - If we run into "critical" bugs, they need fixing.
+  - "Critical" means Mocha is broken w/o workarounds for a *large percentage* of users
+  - Otherwise: respond to issues, close new dupe issues, confirm bugs, ask for more info, etc.
+
+Once we gain ground on the above items, we can work together formalize our contribution guidelines and governance.  For further info & ideas, please see our [projects](https://github.com/mochajs/mocha/projects/).
+
+*You needn't be a maintainer to submit a pull request for test coverage!*
+

+
+// 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.

+# ms
+
+[![Build Status](https://travis-ci.org/zeit/ms.svg?branch=master)](https://travis-ci.org/zeit/ms)
+[![Slack Channel](http://zeit-slackin.now.sh/badge.svg)](https://zeit.chat/)
+
+Use this package to easily convert various time formats to milliseconds.
+
+## Examples
+
+```js
+ms('2 days')  // 172800000
+ms('1d')      // 86400000
+ms('10h')     // 36000000
+ms('2.5 hrs') // 9000000
+ms('2h')      // 7200000
+ms('1m')      // 60000
+ms('5s')      // 5000
+ms('1y')      // 31557600000
+ms('100')     // 100
+```
+
+### Convert from milliseconds
+
+```js
+ms(60000)             // "1m"
+ms(2 * 60000)         // "2m"
+ms(ms('10 hours'))    // "10h"
+```
+
+### Time format written-out
+
+```js
+ms(60000, { long: true })             // "1 minute"
+ms(2 * 60000, { long: true })         // "2 minutes"
+ms(ms('10 hours'), { long: true })    // "10 hours"
+```
+
+## Features
+
+- Works both in [node](https://nodejs.org) and in the browser.
+- If a number is supplied to `ms`, a string with a unit is returned.
+- 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.
+
+## Caught a bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, node will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`

+# once
+
+Only call a function once.
+
+## usage
+
+```javascript
+var once = require('once')
+
+function load (file, cb) {
+  cb = once(cb)
+  loader.load('file')
+  loader.once('load', cb)
+  loader.once('error', cb)
+}
+```
+
+Or add to the Function.prototype in a responsible way:
+
+```javascript
+// only has to be done once
+require('once').proto()
+
+function load (file, cb) {
+  cb = cb.once()
+  loader.load('file')
+  loader.once('load', cb)
+  loader.once('error', cb)
+}
+```
+
+Ironically, the prototype feature makes this module twice as
+complicated as necessary.
+
+To check whether you function has been called, use `fn.called`. Once the
+function is called for the first time the return value of the original
+function is saved in `fn.value` and subsequent calls will continue to
+return this value.
+
+```javascript
+var once = require('once')
+
+function load (cb) {
+  cb = once(cb)
+  var stream = createStream()
+  stream.once('data', cb)
+  stream.once('end', function () {
+    if (!cb.called) cb(new Error('not found'))
+  })
+}
+```
+
+## `once.strict(func)`
+
+Throw an error if the function is called twice.
+
+Some functions are expected to be called only once. Using `once` for them would
+potentially hide logical errors.
+
+In the example below, the `greet` function has to call the callback only once:
+
+```javascript
+function greet (name, cb) {
+  // return is missing from the if statement
+  // when no name is passed, the callback is called twice
+  if (!name) cb('Hello anonymous')
+  cb('Hello ' + name)
+}
+
+function log (msg) {
+  console.log(msg)
+}
+
+// this will print 'Hello anonymous' but the logical error will be missed
+greet(null, once(msg))
+
+// once.strict will print 'Hello anonymous' and throw an error when the callback will be called the second time
+greet(null, once.strict(msg))
+```

+## What is pathval?
+
+Pathval is a module which you can use to retrieve or set an Object's property for a given `String` path.
+
+## Installation
+
+### Node.js
+
+`pathval` is available on [npm](http://npmjs.org). To install it, type:
+
+    $ npm install pathval
+
+### Browsers
+
+You can also use it within the browser; install via npm and use the `pathval.js` file found within the download. For example:
+
+```html
+
+```
+
+## Usage
+
+The primary export of `pathval` is an object which has the following methods:
+
+* `hasProperty(object, name)` - Checks whether an `object` has `name`d property or numeric array index.
+* `getPathInfo(object, path)` - Returns an object with info indicating the value of the `parent` of that path, the `name ` of the property we're retrieving and its `value`.
+* `getPathValue(object, path)` - Retrieves the value of a property at a given `path` inside an `object`'.
+* `setPathValue(object, path, value)` - Sets the `value` of a property at a given `path` inside an `object`'.
+
+```js
+var pathval = require('pathval');
+```
+
+#### .hasProperty(object, name)
+
+```js
+var pathval = require('pathval');
+
+var obj = { prop: 'a value' };
+pathval.hasProperty(obj, 'prop'); // true
+```
+
+#### .getPathInfo(object, path)
+
+```js
+var pathval = require('pathval');
+
+var obj = { earth: { country: 'Brazil' } };
+pathval.getPathInfo(obj, 'earth.country'); // { parent: { country: 'Brazil'  }, name: 'country', value: 'Brazil', exists: true }
+```
+
+#### .getPathValue(object, path)
+
+```js
+var pathval = require('pathval');
+
+var obj = { earth: { country: 'Brazil' } };
+pathval.getPathValue(obj, 'earth.country'); // 'Brazil'
+```
+
+#### .setPathValue(object, path, value)
+
+```js
+var pathval = require('pathval');
+
+var obj = { earth: { country: 'Brazil' } };
+pathval.setPathValue(obj, 'earth.country', 'USA');
+
+obj.earth.country; // 'USA'
+```

+# supports-color [![Build Status](https://travis-ci.org/chalk/supports-color.svg?branch=master)](https://travis-ci.org/chalk/supports-color)
+
+> Detect whether a terminal supports color
+
+
+## Install
+
+```
+$ npm install supports-color
+```
+
+
+## Usage
+
+```js
+const supportsColor = require('supports-color');
+
+if (supportsColor) {
+	console.log('Terminal supports color');
+}
+
+if (supportsColor.has256) {
+	console.log('Terminal supports 256 colors');
+}
+
+if (supportsColor.has16m) {
+	console.log('Terminal supports 16 million colors (truecolor)');
+}
+```
+
+
+## API
+
+Returns an `Object`, or `false` if color is not supported.
+
+The returned object specifies a level of support for color through a `.level` property and a corresponding flag:
+
+- `.level = 1` and `.hasBasic = true`: Basic color support (16 colors)
+- `.level = 2` and `.has256 = true`: 256 color support
+- `.level = 3` and `.has16m = true`: Truecolor support (16 million colors)
+
+
+## Info
+
+It obeys the `--color` and `--no-color` CLI flags.
+
+Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, add the environment variable `FORCE_COLOR=1` to forcefully enable color or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
+
+Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.

+## What is Type-Detect?
+
+Type Detect is a module which you can use to detect the type of a given object. It returns a string representation of the object's type, either using [`typeof`](http://www.ecma-international.org/ecma-262/6.0/index.html#sec-typeof-operator) or [`@@toStringTag`](http://www.ecma-international.org/ecma-262/6.0/index.html#sec-symbol.tostringtag). It also normalizes some object names for consistency among browsers.
+
+## Why?
+
+The `typeof` operator will only specify primitive values; everything else is `"object"` (including `null`, arrays, regexps, etc). Many developers use `Object.prototype.toString()` - which is a fine alternative and returns many more types (null returns `[object Null]`, Arrays as `[object Array]`, regexps as `[object RegExp]` etc). 
+
+Sadly, `Object.prototype.toString` is slow, and buggy. By slow - we mean it is slower than `typeof`. By buggy - we mean that some values (like Promises, the global object, iterators, dataviews, a bunch of HTML elements) all report different things in different browsers.
+
+`type-detect` fixes all of the shortcomings with `Object.prototype.toString`. We have extra code to speed up checks of JS and DOM objects, as much as 20-30x faster for some values. `type-detect` also fixes any consistencies with these objects.
+
+## Installation
+
+### Node.js
+
+`type-detect` is available on [npm](http://npmjs.org). To install it, type:
+
+    $ npm install type-detect
+
+### Browsers
+
+You can also use it within the browser; install via npm and use the `type-detect.js` file found within the download. For example:
+
+```html
+
+```
+
+## Usage
+
+The primary export of `type-detect` is function that can serve as a replacement for `typeof`. The results of this function will be more specific than that of native `typeof`.
+
+```js
+var type = require('type-detect');
+```
+
+#### array
+
+```js
+assert(type([]) === 'Array');
+assert(type(new Array()) === 'Array');
+```
+
+#### regexp
+
+```js
+assert(type(/a-z/gi) === 'RegExp');
+assert(type(new RegExp('a-z')) === 'RegExp');
+```
+
+#### function
+
+```js
+assert(type(function () {}) === 'function');
+```
+
+#### arguments
+
+```js
+(function () {
+  assert(type(arguments) === 'Arguments');
+})();
+```
+
+#### date
+
+```js
+assert(type(new Date) === 'Date');
+```
+
+#### number
+
+```js
+assert(type(1) === 'number');
+assert(type(1.234) === 'number');
+assert(type(-1) === 'number');
+assert(type(-1.234) === 'number');
+assert(type(Infinity) === 'number');
+assert(type(NaN) === 'number');
+assert(type(new Number(1)) === 'Number'); // note - the object version has a capital N
+```
+
+#### string
+
+```js
+assert(type('hello world') === 'string');
+assert(type(new String('hello')) === 'String'); // note - the object version has a capital S
+```
+
+#### null
+
+```js
+assert(type(null) === 'null');
+assert(type(undefined) !== 'null');
+```
+
+#### undefined
+
+```js
+assert(type(undefined) === 'undefined');
+assert(type(null) !== 'undefined');
+```
+
+#### object
+
+```js
+var Noop = function () {};
+assert(type({}) === 'Object');
+assert(type(Noop) !== 'Object');
+assert(type(new Noop) === 'Object');
+assert(type(new Object) === 'Object');
+```
+
+#### ECMA6 Types
+
+All new ECMAScript 2015 objects are also supported, such as Promises and Symbols:
+
+```js
+assert(type(new Map() === 'Map');
+assert(type(new WeakMap()) === 'WeakMap');
+assert(type(new Set()) === 'Set');
+assert(type(new WeakSet()) === 'WeakSet');
+assert(type(Symbol()) === 'symbol');
+assert(type(new Promise(callback) === 'Promise');
+assert(type(new Int8Array()) === 'Int8Array');
+assert(type(new Uint8Array()) === 'Uint8Array');
+assert(type(new UInt8ClampedArray()) === 'Uint8ClampedArray');
+assert(type(new Int16Array()) === 'Int16Array');
+assert(type(new Uint16Array()) === 'Uint16Array');
+assert(type(new Int32Array()) === 'Int32Array');
+assert(type(new UInt32Array()) === 'Uint32Array');
+assert(type(new Float32Array()) === 'Float32Array');
+assert(type(new Float64Array()) === 'Float64Array');
+assert(type(new ArrayBuffer()) === 'ArrayBuffer');
+assert(type(new DataView(arrayBuffer)) === 'DataView');
+```
+
+Also, if you use `Symbol.toStringTag` to change an Objects return value of the `toString()` Method, `type()` will return this value, e.g:
+
+```js
+var myObject = {};
+myObject[Symbol.toStringTag] = 'myCustomType';
+assert(type(myObject) === 'myCustomType');
+```
