+# grunt-contrib-clean v0.6.0 [![Build Status: Linux](https://travis-ci.org/gruntjs/grunt-contrib-clean.png?branch=master)](https://travis-ci.org/gruntjs/grunt-contrib-clean) <a href="https://ci.appveyor.com/project/gruntjs/grunt-contrib-clean"><img src="https://ci.appveyor.com/api/projects/status/li28411ceq3n833d/branch/master" alt="Build Status: Windows" height="18" /></a>
+
+> Clean files and folders.
+
+
+
+## Getting Started
+This plugin requires Grunt `~0.4.0`
+
+If you haven't used [Grunt](http://gruntjs.com/) before, be sure to check out the [Getting Started](http://gruntjs.com/getting-started) guide, as it explains how to create a [Gruntfile](http://gruntjs.com/sample-gruntfile) as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:
+
+```shell
+npm install grunt-contrib-clean --save-dev
+```
+
+Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:
+
+```js
+grunt.loadNpmTasks('grunt-contrib-clean');
+```
+
+*This plugin was designed to work with Grunt 0.4.x. If you're still using grunt v0.3.x it's strongly recommended that [you upgrade](http://gruntjs.com/upgrading-from-0.3-to-0.4), but in case you can't please use [v0.3.2](https://github.com/gruntjs/grunt-contrib-clean/tree/grunt-0.3-stable).*
+
+
+
+## Clean task
+_Run this task with the `grunt clean` command._
+
+Task targets, files and options may be specified according to the grunt [Configuring tasks](http://gruntjs.com/configuring-tasks) guide.
+
+*Due to the destructive nature of this task, always be cautious of the paths you clean.*
+### Options
+
+#### force
+Type: `Boolean`  
+Default: false
+
+This overrides this task from blocking deletion of folders outside current working dir (CWD). Use with caution.
+
+#### no-write
+Type: `Boolean`  
+Default: false
+
+Will log messages of what would happen if the task was ran but doesn't actually delete the files.
+
+### Usage Examples
+
+There are three formats you can use to run this task.
+
+#### Short
+
+```js
+clean: ["path/to/dir/one", "path/to/dir/two"]
+```
+
+#### Medium (specific targets with global options)
+
+```js
+clean: {
+  build: ["path/to/dir/one", "path/to/dir/two"],
+  release: ["path/to/another/dir/one", "path/to/another/dir/two"]
+},
+```
+
+#### Long (specific targets with per target options)
+
+```js
+clean: {
+  build: {
+    src: ["path/to/dir/one", "path/to/dir/two"]
+  }
+}
+```
+
+##### Skipping Files
+
+```js
+// Deletes all .js files, but skips min.js files
+clean: {
+  js: ["path/to/dir/*.js", "!path/to/dir/*.min.js"]
+}
+```
+
+"Compact" and "Files Array" formats support a few [additional properties](http://gruntjs.com/configuring-tasks#files)
+which help you deal with hidden files, process dynamic mappings and so on.
+
+
+## Release History
+
+ * 2014-07-27   v0.6.0   Less verbose output. README updates.
+ * 2013-07-15   v0.5.0   Use rimraf directly, version 2.2.1 to fix issue on Windows. Add no-write option to mimic grunt.file.delete behavior.
+ * 2013-04-16   v0.4.1   Check if file exists to avoid trying to delete a non-existent file.
+ * 2013-02-15   v0.4.0   First official release for Grunt 0.4.0.
+ * 2013-01-18   v0.4.0rc6   Updating grunt/gruntplugin dependencies to rc6. Changing in-development grunt/gruntplugin dependency versions from tilde version ranges to specific versions.
+ * 2013-01-09   v0.4.0rc5   Updating to work with grunt v0.4.0rc5. Switching to this.filesSrc api.
+ * 2012-12-07   v0.4.0a   Conversion to grunt v0.4 conventions. Remove node v0.6 and grunt v0.3 support. Add force option to bypass CWD check.

+`rm -rf` for node.
+
+Install with `npm install rimraf`, or just drop rimraf.js somewhere.
+
+## API
+
+`rimraf(f, callback)`
+
+The callback will be called with an error if there is one.  Certain
+errors are handled for you:
+
+* Windows: `EBUSY` and `ENOTEMPTY` - rimraf will back off a maximum of
+  `opts.maxBusyTries` times before giving up.
+* `ENOENT` - If the file doesn't exist, rimraf will return
+  successfully, since your desired outcome is already the case.
+
+## rimraf.sync
+
+It can remove stuff synchronously, too.  But that's not so good.  Use
+the async API.  It's better.
+
+## CLI
+
+If installed with `npm install rimraf -g` it can be used as a global
+command `rimraf <path>` which is useful for cross platform support.
+
+## mkdirp
+
+If you need to create a directory recursively, check out
+[mkdirp](https://github.com/substack/node-mkdirp).

+# grunt-istanbul [![Build Status](https://travis-ci.org/taichi/grunt-istanbul.png)](https://travis-ci.org/taichi/grunt-istanbul)
+
+JavaScript codecoverage tool for Grunt
+
+## Getting Started
+This plugin requires Grunt ~0.4.1
+
+Install this grunt plugin next to your project's [Gruntfile.js][getting_started] with: `npm install grunt-istanbul`
+
+Then add this line to your project's `Gruntfile.js` gruntfile:
+
+```javascript
+grunt.loadNpmTasks('grunt-istanbul');
+```
+
+[grunt]: https://github.com/cowboy/grunt
+[getting_started]: https://github.com/cowboy/grunt/blob/master/docs/getting_started.md
+
+## Documentation
+To use this grunt-istanbul plugin, register a grunt task to run the following:
+
+1. Instrument your source code
+2. Run your test suite against your instrumented source code
+3. Store your coverage results
+4. Make the report
+
+For step 2, an environment variable can be used to determine which path to use for loading
+the source code to run the tests against. For example, when you normally run your tests you
+want them to point directly at your source code. But when you run your instanbul code coverage
+task you want your tests to point at your instrumented source code. The `grunt-env` plugin
+can be used for setting an environment variable in a grunt task. Here's an example solution
+that solves this problem using `grunt-env` and `grunt-mocha-test`:
+
+```javascript
+// in Gruntfile.js
+module.exports = function (grunt) {
+
+  grunt.initConfig({
+    env: {
+      coverage: {
+        APP_DIR_FOR_CODE_COVERAGE: '../test/coverage/instrument/app/'
+      }
+    },
+    instrument: {
+      files: 'app/*.js',
+      options: {
+        lazy: true,
+        basePath: 'test/coverage/instrument/'
+      }
+    },
+    mochaTest: {
+      options: {
+        reporter: 'spec'
+      },
+      src: ['test/*.js']
+    },
+    storeCoverage: {
+      options: {
+        dir: 'test/coverage/reports'
+      }
+    },
+    makeReport: {
+      src: 'test/coverage/reports/**/*.json',
+      options: {
+        type: 'lcov',
+        dir: 'test/coverage/reports',
+        print: 'detail'
+      }
+    }
+  });
+
+  grunt.registerTask('coverage', ['env:coverage', 'instrument', 'mochaTest',
+    'storeCoverage', 'makeReport']);
+};
+
+
+// require_helper.js
+module.exports = function (path) {
+  return require((process.env.APP_DIR_FOR_CODE_COVERAGE || '../app/') + path);
+};
+
+// using requireHelper in a test
+var requireHelper = require('../require_helper');
+var formValidator = requireHelper('form_validator');
+```
+
+Also, checkout the example Gruntfile.js in this repo (note that you do not need to implement the
+`reloadTasks` task in this example):

+Istanbul - a JS code coverage tool written in JS
+================================================
+
+[![Build Status](https://secure.travis-ci.org/gotwarlost/istanbul.png)](http://travis-ci.org/gotwarlost/istanbul)
+[![Dependency Status](https://gemnasium.com/gotwarlost/istanbul.png)](https://gemnasium.com/gotwarlost/istanbul)
+[![Coverage Status](https://img.shields.io/coveralls/gotwarlost/istanbul.svg)](https://coveralls.io/r/gotwarlost/istanbul?branch=master)
+
+[![NPM](https://nodei.co/npm/istanbul.png?downloads=true)](https://nodei.co/npm/istanbul/)
+
+Features
+--------
+
+* All-javascript instrumentation library that tracks **statement, branch,
+and function coverage** and reverse-engineers **line coverage** with 100% fidelity.
+* **Module loader hooks** to instrument code on the fly
+* **Command line tools** to run node unit tests "with coverage turned on" and no cooperation
+whatsoever from the test runner
+* **HTML**, **LCOV**, **Cobertura**, **TeamCity**, and **Clover** reporting.
+* Ability to use as **middleware** when serving JS files that need to be tested on the browser.
+* Can be used on the **command line** as well as a **library**
+* Based on the awesome `esprima` parser and the equally awesome `escodegen` code generator
+* Well-tested on node 0.4.x, 0.6.x, 0.8.x and the browser (instrumentation library only)
+
+Installing
+----------
+
+    $ npm install -g istanbul
+
+Getting started
+---------------
+
+The best way to see it in action is to run node unit tests. Say you have a test
+script `test.js` that runs all tests for your node project without coverage.
+
+Simply:
+
+    $ cd /path/to/your/source/root
+    $ istanbul cover test.js
+
+and this should produce a `coverage.json`, `lcov.info` and `lcov-report/*html` under `./coverage`
+
+Sample of code coverage reports produced by this tool (for this tool!):
+
+* [HTML reports](http://gotwarlost.github.com/istanbul/public/coverage/lcov-report/index.html)
+* [Standard LCOV reports](http://gotwarlost.github.com/istanbul/public/coverage/std-lcov/index.html) (using `genhtml` on the lcov trace file)
+
+Use cases
+---------
+
+Supports the following use cases and more
+
+* transparent coverage of nodejs unit tests
+* ability to use in an <code>npm test</code> script for conditional coverage
+* instrumentation of files in batch mode for browser tests (using yeti for example)
+* Server side code coverage for nodejs by embedding it as custom middleware
+
+
+Ignoring code for coverage
+--------------------------
+
+* Skip an `if` or `else` path with `/* istanbul ignore if */` or `/* istanbul ignore else */` respectively.
+* For all other cases, skip the next 'thing' in the source with: `/* istanbul ignore next */`
+
+See [ignoring-code-for-coverage.md](ignoring-code-for-coverage.md) for the spec.
+
+The command line
+----------------
+
+    $ istanbul help
+
+gives you detailed help on all commands.
+
+Usage: istanbul help <command>
+
+Available commands are:
+
+      check-coverage
+              checks overall coverage against thresholds from coverage JSON
+              files. Exits 1 if thresholds are not met, 0 otherwise
+
+
+      cover   transparently adds coverage information to a node command. Saves
+              coverage.json and reports at the end of execution
+
+
+      help    shows help
+
+
+      instrument
+              instruments a file or a directory tree and writes the
+              instrumented code to the desired output location
+
+
+      report  writes reports for coverage JSON objects produced in a previous
+              run
+
+
+      test    cover a node command only when npm_config_coverage is set. Use in
+              an `npm test` script for conditional coverage
+
+
+Command names can be abbreviated as long as the abbreviation is unambiguous
+
+The `cover` command
+-------------------
+
+    $ istanbul cover my-test-script.js -- my test args
+    # note the -- between the command name and the arguments to be passed
+
+The `cover` command can be used to get a coverage object and reports for any arbitrary
+node script. By default, coverage information is written under `./coverage` - this
+can be changed using command-line options.
+
+The `cover` command can also be passed an optional `--handle-sigint` flag to enable writing reports when a user triggers a manual SIGINT of the process that is being covered. This can be useful when you are generating coverage for a long lived process.
+
+The `test` command
+-------------------
+
+The `test` command has almost the same behavior as the `cover` command, except that
+it skips coverage unless the `npm_config_coverage` environment variable is set.
+
+This helps you set up conditional coverage for tests. In this case you would
+have a `package.json` that looks as follows.
+
+    {
+        "name": "my-awesome-lib",
+        "version": "1.0",
+        "script": {
+            "test": "istanbul test my-test-file.js"
+        }
+    }
+
+Then:
+
+    $ npm test # will run tests without coverage
+
+And:
+
+    $ npm test --coverage # will run tests with coverage
+
+**Note**: This needs `node 0.6` or better to work. `npm` for `node 0.4.x` does
+not support the `--coverage` flag.
+
+The `instrument` command
+------------------------
+
+Instruments a single JS file or an entire directory tree and produces an output directory tree with instrumented code. This should not be required for running node unit tests but is useful for tests to be run on the browser (using `yeti` for example).
+
+The `report` command
+-------------------
+
+Writes reports using `coverage*.json` files as the source of coverage information. Reports are available in the following formats:
+
+* html - produces a bunch of HTML files with annotated source code
+* lcovonly - produces an lcov.info file
+* lcov - produces html + lcov files. This is the default format
+* cobertura - produces a cobertura-coverage.xml file for easy Hudson integration
+* text-summary - produces a compact text summary of coverage, typically to console
+* text - produces a detailed text table with coverage for all files
+* teamcity - produces service messages to report code coverage to TeamCity
+* clover - produces a clover.xml file to integrate with Atlassian Clover
+
+Additional report formats may be plugged in at the library level.
+
+The `check-coverage` command
+----------------------------
+
+Checks the coverage of statements, functions, branches, and lines against the
+provided thresholds. Postive thresholds are taken to be the minimum percentage
+required and negative numbers are taken to be the number of uncovered entities
+allowed.
+
+Library usage
+-------------
+
+All the features of istanbul can be accessed as a library using its [public API](http://gotwarlost.github.com/istanbul/public/apidocs/index.html)

+
+Inspired by
+-----------
+
+* YUI test coverage - https://github.com/yui/yuitest - the grand-daddy of JS coverage tools. Istanbul has been specifically designed to offer an alternative to this library with an easy migration path.
+* cover: https://github.com/itay/node-cover - the inspiration for the `cover` command, modeled after the `run` command in that tool. The coverage methodology used by istanbul is quite different, however
+
+Shout out to
+------------
+
+   * [mfncooper](https://github.com/mfncooper) - for great brainstorming discussions
+   * [reid](https://github.com/reid), [davglass](https://github.com/davglass), the YUI dudes, for interesting conversations, encouragement, support and gentle pressure to get it done :)
+
+Why the funky name?
+-------------------
+
+Since all the good ones are taken. Comes from the loose association of ideas across coverage, carpet-area coverage, the country that makes good carpets and so on...

+/**
+ * provides a mechanism to transform code in the scope of `require` or `vm.createScript`.
+ * This mechanism is general and relies on a user-supplied `matcher` function that determines when transformations should be
+ * performed and a user-supplied `transformer` function that performs the actual transform.
+ * Instrumenting code for coverage is one specific example of useful hooking.
+ *
+ * Note that both the `matcher` and `transformer` must execute synchronously.
+ *
+ * For the common case of matching filesystem paths based on inclusion/ exclusion patterns, use the `matcherFor`
+ * function in the istanbul API to get a matcher.
+ *
+ * It is up to the transformer to perform processing with side-effects, such as caching, storing the original
+ * source code to disk in case of dynamically generated scripts etc. The `Store` class can help you with this.
+ *
+ * Usage
+ * -----
+ *
+ *      var hook = require('istanbul').hook,
+ *          myMatcher = function (file) { return file.match(/foo/); },
+ *          myTransformer = function (code, file) { return 'console.log("' + file + '");' + code; };

+     *
+     * Works on `node` as well as the browser.
+     *
+     * Usage on nodejs
+     * ---------------

+     *          changed = instrumenter.instrumentSync('function meaningOfLife() { return 42; }', 'filename.js');
+     *
+     * Usage in a browser
+     * ------------------
+     *
+     * Load `esprima.js`, `escodegen.js` and `instrumenter.js` (this file) using `script` tags or other means.
+     *
+     * Create an instrumenter object as:
+     *
+     *      var instrumenter = new Instrumenter(),
+     *          changed = instrumenter.instrumentSync('function meaningOfLife() { return 42; }', 'filename.js');
+     *
+     * Aside from demonstration purposes, it is unclear why you would want to instrument code in a browser.
+     *
+     * @class Instrumenter
+     * @constructor
+     * @param {Object} options Optional. Configuration options.

+     *      tracking coverage. Defaults to `__coverage__`
+     * @param {Boolean} [options.embedSource] whether to embed the source code of every
+     *      file as an array in the file coverage object for that file. Defaults to `false`
+     * @param {Boolean} [options.preserveComments] whether comments should be preserved in the output. Defaults to `false`
+     * @param {Boolean} [options.noCompact] emit readable code when set. Defaults to `false`
+     * @param {Boolean} [options.noAutoWrap] do not automatically wrap the source in
+     *      an anonymous function before covering it. By default, code is wrapped in
+     *      an anonymous function before it is parsed. This is done because
+     *      some nodejs libraries have `return` statements outside of
+     *      a function which is technically invalid Javascript and causes the parser to fail.
+     *      This construct, however, works correctly in node since module loading
+     *      is done in the context of an anonymous function.
+     *
+     * Note that the semantics of the code *returned* by the instrumenter does not change in any way.
+     * The function wrapper is "unwrapped" before the instrumented code is generated.
+     * @param {Object} [options.codeGenerationOptions] an object that is directly passed to the `escodegen`
+     *      library as configuration for code generation. The `noCompact` setting is not honored when this
+     *      option is specified
+     * @param {Boolean} [options.debug] assist in debugging. Currently, the only effect of
+     *      setting this option is a pretty-print of the coverage variable. Defaults to `false`
+     * @param {Boolean} [options.walkDebug] assist in debugging of the AST walker used by this class.

+ * utility methods to process coverage objects. A coverage object has the following
+ * format.
+ *
+ *      {
+ *          "/path/to/file1.js": { file1 coverage },
+ *          "/path/to/file2.js": { file2 coverage }
+ *      }
+ *
+ *  The internals of the file coverage object are intentionally not documented since
+ *  it is not a public interface.
+ *
+ *  *Note:* When a method of this module has the word `File` in it, it will accept
+ *  one of the sub-objects of the main coverage object as an argument. Other
+ *  methods accept the higher level coverage object with multiple keys.
+ *
+ * Works on `node` as well as the browser.
+ *
+ * Usage on nodejs
+ * ---------------
+ *
+ *      var objectUtils = require('istanbul').utils;
+ *
+ * Usage in a browser
+ * ------------------
+ *
+ * Load this file using a `script` tag or other means. This will set `window.coverageUtils`

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

+### Escodegen [![Build Status](https://secure.travis-ci.org/Constellation/escodegen.svg)](http://travis-ci.org/Constellation/escodegen) [![Build Status](https://drone.io/github.com/Constellation/escodegen/status.png)](https://drone.io/github.com/Constellation/escodegen/latest)
+
+Escodegen ([escodegen](http://github.com/Constellation/escodegen)) is
+[ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
+(also popularly known as [JavaScript](http://en.wikipedia.org/wiki/JavaScript>JavaScript))
+code generator from [Parser API](https://developer.mozilla.org/en/SpiderMonkey/Parser_API) AST.
+See [online generator demo](http://constellation.github.com/escodegen/demo/index.html).
+
+
+### Install
+
+Escodegen can be used in a web browser:
+
+    <script src="escodegen.browser.js"></script>
+
+escodegen.browser.js is found in tagged-revision. See Tags on GitHub.
+
+Or in a Node.js application via the package manager:
+
+    npm install escodegen
+
+### Usage
+
+A simple example: the program
+
+    escodegen.generate({
+        type: 'BinaryExpression',
+        operator: '+',
+        left: { type: 'Literal', value: 40 },
+        right: { type: 'Literal', value: 2 }
+    });
+
+produces the string `'40 + 2'`
+
+See the [API page](https://github.com/Constellation/escodegen/wiki/API) for
+options. To run the tests, execute `npm test` in the root directory.
+
+### Building browser bundle / minified browser bundle
+
+At first, executing `npm install` to install the all dev dependencies.
+After that,
+
+    npm run-script build
+
+will generate `escodegen.browser.js`, it is used on the browser environment.
+
+And,
+
+    npm run-script build-min
+
+will generate minified `escodegen.browser.min.js`.
