+# grunt-contrib-watch v1.1.0 [![Build Status: Linux](https://travis-ci.org/gruntjs/grunt-contrib-watch.svg?branch=master)](https://travis-ci.org/gruntjs/grunt-contrib-watch) [![Build Status: Windows](https://ci.appveyor.com/api/projects/status/olyu3uhcq59avm8v/branch/master?svg=true)](https://ci.appveyor.com/project/gruntjs/grunt-contrib-watch/branch/master)
+
+> Run predefined tasks whenever watched file patterns are added, changed or deleted
+
+
+
+## Getting Started
+
+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-watch --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-watch');
+```
+
+
+
+
+## Watch task
+_Run this task with the `grunt watch` command._
+
+
+### Settings
+
+There are a number of options available. Please review the [minimatch options here](https://github.com/isaacs/minimatch#options). As well as some additional options as follows:
+
+#### files
+Type: `String|Array`
+
+This defines what file patterns this task will watch. It can be a string or an array of files and/or minimatch patterns.
+
+#### tasks
+Type: `String|Array`
+
+This defines which tasks to run when a watched file event occurs.
+
+#### options.spawn
+Type: `Boolean`  
+Default: `true`
+
+Whether to spawn task runs in a child process. Setting this option to `false` speeds up the reaction time of the watch (usually 500ms faster for most) and allows subsequent task runs to share the same context. Not spawning task runs can make the watch more prone to failing so please use as needed.
+
+Example:
+```js
+watch: {
+  scripts: {
+    files: ['**/*.js'],
+    tasks: ['jshint'],
+    options: {
+      spawn: false,
+    },
+  },
+},
+```
+
+*For backwards compatibility the option `nospawn` is still available and will do the opposite of `spawn`.*
+
+#### options.interrupt
+Type: `Boolean`  
+Default: `false`
+
+As files are modified this watch task will spawn tasks in child processes. The default behavior will only spawn a new child process per target when the previous process has finished. Set the `interrupt` option to true to terminate the previous process and spawn a new one upon later changes.
+
+Example:
+```js
+watch: {
+  scripts: {
+    files: '**/*.js',
+    tasks: ['jshint'],
+    options: {
+      interrupt: true,
+    },
+  },
+},
+```
+
+#### options.debounceDelay
+Type: `Integer`  
+Default: `500`
+
+How long to wait before emitting events in succession for the same filepath and status. For example if your `Gruntfile.js` file was `changed`, a `changed` event will only fire again after the given milliseconds.
+
+Example:
+```js
+watch: {
+  scripts: {
+    files: '**/*.js',
+    tasks: ['jshint'],
+    options: {
+      debounceDelay: 250,
+    },
+  },
+},
+```
+
+#### options.interval
+Type: `Integer`  
+Default: `100`
+
+The `interval` is passed to `fs.watchFile`. Since `interval` is only used by `fs.watchFile` and this watcher also uses `fs.watch`; it is recommended to ignore this option. *Default is 100ms*.
+
+#### options.event
+Type: `String|Array`  
+Default: `'all'`
+
+Specify the type of watch events that triggers the specified task. This option can be one or many of: `'all'`, `'changed'`, `'added'` and `'deleted'`.
+
+Example:
+```js
+watch: {
+  scripts: {
+    files: '**/*.js',
+    tasks: ['generateFileManifest'],
+    options: {
+      event: ['added', 'deleted'],
+    },
+  },
+},
+```
+
+#### options.reload
+Type: `Boolean`  
+Default: `false`
+
+By default, if `Gruntfile.js` is being watched, then changes to it will trigger the watch task to restart, and reload the `Gruntfile.js` changes.
+When `reload` is set to `true`, changes to *any* of the watched files will trigger the watch task to restart.
+This is especially useful if your `Gruntfile.js` is dependent on other files.
+
+```js
+watch: {
+  configFiles: {
+    files: [ 'Gruntfile.js', 'config/*.js' ],
+    options: {
+      reload: true
+    }
+  }
+}
+```
+
+
+#### options.forever
+Type: `Boolean`  
+Default: `true`
+
+This is *only a task level option* and cannot be configured per target. By default the watch task will duck punch `grunt.fatal` and `grunt.warn` to try and prevent them from exiting the watch process. If you don't want `grunt.fatal` and `grunt.warn` to be overridden set the `forever` option to `false`.
+
+#### options.dateFormat
+Type: `Function`
+
+This is *only a task level option* and cannot be configured per target. By default when the watch has finished running tasks it will display the message `Completed in 1.301s at Thu Jul 18 2013 14:58:21 GMT-0700 (PDT) - Waiting...`. You can override this message by supplying your own function:
+
+```js
+watch: {
+  options: {
+    dateFormat: function(time) {
+      grunt.log.writeln('The watch finished in ' + time + 'ms at' + (new Date()).toString());
+      grunt.log.writeln('Waiting for more changes...');
+    },
+  },
+  scripts: {
+    files: '**/*.js',
+    tasks: 'jshint',
+  },
+},
+```
+
+#### options.atBegin
+Type: `Boolean`  
+Default: `false`
+
+This option will trigger the run of each specified task at startup of the watcher.
+
+#### options.livereload
+Type: `Boolean|Number|Object`  
+Default: `false`
+
+Set to `true` or set `livereload: 1337` to a port number to enable live reloading. Default and recommended port is `35729`.
+
+If enabled a live reload server will be started with the watch task per target. Then after the indicated tasks have run, the live reload server will be triggered with the modified files.
+
+See also how to [enable livereload on your HTML](https://github.com/gruntjs/grunt-contrib-watch/blob/master/docs/watch-examples.md#enabling-live-reload-in-your-html).
+
+Example:
+```js
+watch: {
+  css: {
+    files: '**/*.sass',
+    tasks: ['sass'],
+    options: {
+      livereload: true,
+    },
+  },
+},
+```
+
+Passing an object to `livereload` allows listening on a specific port and hostname/IP or over https connections (by specifying `key` and `cert` paths).
+
+Example:
+```js
+watch: {
+  css: {
+    files: '**/*.sass',
+    tasks: ['sass'],
+    options: {
+      livereload: {
+        host: 'localhost',
+        port: 9000,
+        key: grunt.file.read('path/to/ssl.key'),
+        cert: grunt.file.read('path/to/ssl.crt')
+        // you can pass in any other options you'd like to the https server, as listed here: http://nodejs.org/api/tls.html#tls_tls_createserver_options_secureconnectionlistener
+      }
+    },
+  },
+},
+```
+
+
+#### options.cwd
+Type: `String|Object`  
+Default: `process.cwd()`
+
+Ability to set the current working directory. Defaults to `process.cwd()`. Can either be a string to set the cwd to match files and spawn tasks or an object to set each independently. Such as:
+```js
+options: {
+  cwd: {
+    files: 'match/files/from/here',
+    spawn: 'but/spawn/files/from/here'
+  }
+}
+```
+
+To strip off a path before emitting events:
+```js
+options: {
+  cwd: {
+    files: 'a/path',
+    event: 'a/path'
+  }
+}
+```
+This will strip off `a/path` before emitting events. This option is useful for specifying the base directory to use with livereload.
+
+
+#### options.livereloadOnError
+Type: `Boolean`  
+Default: `true`  
+
+Option to prevent the livereload if the executed tasks encountered an error. If set to `false`, the livereload will only be triggered if all tasks completed successfully.
+
+### Examples
+
+```js
+// Simple config to run jshint any time a file is added, changed or deleted
+grunt.initConfig({
+  watch: {
+    files: ['**/*'],
+    tasks: ['jshint'],
+  },
+});
+```
+
+```js
+// Advanced config. Run specific tasks when specific files are added, changed or deleted.
+grunt.initConfig({
+  watch: {
+    gruntfile: {
+      files: 'Gruntfile.js',
+      tasks: ['jshint:gruntfile'],
+    },
+    src: {
+      files: ['lib/*.js', 'css/**/*.scss', '!lib/dontwatch.js'],
+      tasks: ['default'],
+    },
+    test: {
+      files: '<%= jshint.test.src %>',
+      tasks: ['jshint:test', 'qunit'],
+    },
+  },
+});
+```
+
+#### Using the `watch` event
+This task will emit a `watch` event when watched files are modified. This is useful if you would like a simple notification when files are edited or if you're using this task in tandem with another task. Here is a simple example using the `watch` event:
+
+```js
+grunt.initConfig({
+  watch: {
+    scripts: {
+      files: ['lib/*.js'],
+    },
+  },
+});
+grunt.event.on('watch', function(action, filepath, target) {
+  grunt.log.writeln(target + ': ' + filepath + ' has ' + action);
+});
+```
+
+**The `watch` event is not intended for replacing the standard Grunt API for configuring and running tasks. If you're trying to run tasks from within the `watch` event you're more than likely doing it wrong. Please read [configuring tasks](http://gruntjs.com/configuring-tasks).**
+
+##### Compiling Files As Needed
+A very common request is to only compile files as needed. Here is an example that will only lint changed files with the `jshint` task:
+
+```js
+grunt.initConfig({
+  watch: {
+    scripts: {
+      files: ['lib/*.js'],
+      tasks: ['jshint'],
+      options: {
+        spawn: false,
+      },
+    },
+  },
+  jshint: {
+    all: {
+      src: ['lib/*.js'],
+    },
+  },
+});
+
+// On watch events configure jshint:all to only run on changed file
+grunt.event.on('watch', function(action, filepath) {
+  grunt.config('jshint.all.src', filepath);
+});
+```
+
+If you need to dynamically modify your config, the `spawn` option must be disabled to keep the watch running under the same context.
+
+If you save multiple files simultaneously you may opt for a more robust method:
+
+```js
+var changedFiles = Object.create(null);
+var onChange = grunt.util._.debounce(function() {
+  grunt.config('jshint.all.src', Object.keys(changedFiles));
+  changedFiles = Object.create(null);
+}, 200);
+grunt.event.on('watch', function(action, filepath) {
+  changedFiles[filepath] = action;
+  onChange();
+});
+```
+
+#### Live Reloading
+Live reloading is built into the watch task. Set the option `livereload` to `true` to enable on the default port `35729` or set to a custom port: `livereload: 1337`.
+
+The simplest way to add live reloading to all your watch targets is by setting `livereload` to `true` at the task level. This will run a single live reload server and trigger the live reload for all your watch targets:
+
+```js
+grunt.initConfig({
+  watch: {
+    options: {
+      livereload: true,
+    },
+    css: {
+      files: ['public/scss/*.scss'],
+      tasks: ['compass'],
+    },
+  },
+});
+```
+
+You can also configure live reload for individual watch targets or run multiple live reload servers. Just be sure if you're starting multiple servers they operate on different ports:
+
+```js
+grunt.initConfig({
+  watch: {
+    css: {
+      files: ['public/scss/*.scss'],
+      tasks: ['compass'],
+      options: {
+        // Start a live reload server on the default port 35729
+        livereload: true,
+      },
+    },
+    another: {
+      files: ['lib/*.js'],
+      tasks: ['anothertask'],
+      options: {
+        // Start another live reload server on port 1337
+        livereload: 1337,
+      },
+    },
+    dont: {
+      files: ['other/stuff/*'],
+      tasks: ['dostuff'],
+    },
+  },
+});
+```
+
+##### Enabling Live Reload in Your HTML
+Once you've started a live reload server you'll be able to access the live reload script. To enable live reload on your page, add a script tag before your closing `</body>` tag pointing to the `livereload.js` script:
+
+```html
+<script src="//localhost:35729/livereload.js"></script>
+```
+
+Feel free to add this script to your template situation and toggle with some sort of `dev` flag.
+
+##### Using Live Reload with the Browser Extension
+Instead of adding a script tag to your page, you can live reload your page by installing a browser extension. Please visit [how do I install and use the browser extensions](http://feedback.livereload.com/knowledgebase/articles/86242-how-do-i-install-and-use-the-browser-extensions-) for help installing an extension for your browser.
+
+Once installed please use the default live reload port `35729` and the browser extension will automatically reload your page without needing the `<script>` tag.
+
+##### Using Connect Middleware
+Since live reloading is used when developing, you may want to disable building for production (and are not using the browser extension). One method is to use Connect middleware to inject the script tag into your page. Try the [connect-livereload](https://github.com/intesso/connect-livereload) middleware for injecting the live reload script into your page.
+
+##### Rolling Your Own Live Reload
+Live reloading is made easy by the library [tiny-lr](https://github.com/mklabs/tiny-lr). It is encouraged to read the documentation for `tiny-lr`. If you would like to trigger the live reload server yourself, simply POST files to the URL: `http://localhost:35729/changed`. Or if you rather roll your own live reload implementation use the following example:
+
+```js
+// Create a live reload server instance
+var lrserver = require('tiny-lr')();
+
+// Listen on port 35729
+lrserver.listen(35729, function(err) { console.log('LR Server Started'); });
+
+// Then later trigger files or POST to localhost:35729/changed
+lrserver.changed({body:{files:['public/css/changed.css']}});
+```
+
+##### Live Reload with Preprocessors
+Any time a watched file is edited with the `livereload` option enabled, the file will be sent to the live reload server. Some edited files you may desire to have sent to the live reload server, such as when preprocessing (`sass`, `less`, `coffeescript`, etc). As any file not recognized will reload the entire page as opposed to just the `css` or `javascript`.
+
+The solution is to point a `livereload` watch target to your destination files:
+
+```js
+grunt.initConfig({
+  sass: {
+    dev: {
+      src: ['src/sass/*.sass'],
+      dest: 'dest/css/index.css',
+    },
+  },
+  watch: {
+    sass: {
+      // We watch and compile sass files as normal but don't live reload here
+      files: ['src/sass/*.sass'],
+      tasks: ['sass'],
+    },
+    livereload: {
+      // Here we watch the files the sass task will compile to
+      // These files are sent to the live reload server after sass compiles to them
+      options: { livereload: true },
+      files: ['dest/**/*'],
+    },
+  },
+});
+```
+
+### FAQs
+
+#### How do I fix the error `EMFILE: Too many opened files.`?
+This is because of your system's max opened file limit. For OSX the default is very low (256). Temporarily increase your limit with `ulimit -n 10480`, the number being the new max limit.
+
+In some versions of OSX the above solution doesn't work. In that case try `launchctl limit maxfiles 10480 10480 ` and restart your terminal. See [here](http://superuser.com/questions/261023/how-to-change-default-ulimit-values-in-mac-os-x-10-6).
+
+#### Can I use this with Grunt v0.3?
+`grunt-contrib-watch@0.1.x` is compatible with Grunt v0.3 but it is highly recommended to upgrade Grunt instead.
+
+#### Why is the watch devouring all my memory/cpu?
+Likely because of an enthusiastic pattern trying to watch thousands of files. Such as `'**/*.js'` but forgetting to exclude the `node_modules` folder with `'!**/node_modules/**'`. Try grouping your files within a subfolder or be more explicit with your file matching pattern.
+
+Another reason if you're watching a large number of files could be the low default `interval`. Try increasing with `options: { interval: 5007 }`. Please see issues [#35](https://github.com/gruntjs/grunt-contrib-watch/issues/35) and [#145](https://github.com/gruntjs/grunt-contrib-watch/issues/145) for more information.
+
+#### Why spawn as child processes as a default?
+The goal of this watch task is as files are changed, run tasks as if they were triggered by the user himself or herself. Each time a user runs `grunt` a process is spawned and tasks are ran in succession. In an effort to keep the experience consistent and continually produce expected results, this watch task spawns tasks as child processes by default.
+
+Sandboxing task runs also allows this watch task to run more stable over long periods of time. As well as more efficiently with more complex tasks and file structures.
+
+Spawning does cause a performance hit (usually 500ms for most environments). It also cripples tasks that rely on the watch task to share the context with each subsequent run (i.e., reload tasks). If you would like a faster watch task or need to share the context please set the `spawn` option to `false`. Just be aware that with this option enabled, the watch task is more prone to failure.
+
+#### How can I have the browser reload for files listed in a task?
+Instead of restarting your server each time a static file is changed, start a static web server using (grunt-contrib-connect)[https://github.com/gruntjs/grunt-contrib-connect].
+
+You'll have the `connect` web server on seperate port ex: port 9000 from your main server. When the 'livereload' option is enabled for 'watch' tasks, it will handle triggerring the live reload server for each tasks and when files are modified, which then server back to main server ex: 3000. The main server must include a script tag or a browser extension to the livereload server in order for the browser automatically.

+
+# v2.3.0
+- Added support for ES2017 `async` functions.  Wherever you can pass a Node-style/CPS function that uses a callback, you can also pass an `async` function.  Previously, you had to wrap `async` functions with `asyncify`.  The caveat is that it will only work if `async` functions are supported natively in your environment, transpiled implementations can't be detected.

+- Create optimized hotpath for `filter` in array case.
+
+# v2.1.2
+- Fixed a stackoverflow bug with `detect`, `some`, `every` on large inputs ([#1293](https://github.com/caolan/async/issues/1293)).
+
+# v2.1.0
+
+- `retry` and `retryable` now support an optional `errorFilter` function that determines if the `task` should retry on the error ([#1256](https://github.com/caolan/async/issues/1256), [#1261](https://github.com/caolan/async/issues/1261))
+- Optimized array iteration in `race`, `cargo`, `queue`, and `priorityQueue` ([#1253](https://github.com/caolan/async/issues/1253))

+- Added [BootStrap scrollspy](http://getbootstrap.com/javascript/#scrollspy) to docs to highlight in the sidebar the current method being viewed  ([#1289](https://github.com/caolan/async/issues/1289), [#1300](https://github.com/caolan/async/issues/1300))
+- Various minor doc fixes ([#1263](https://github.com/caolan/async/issues/1263), [#1264](https://github.com/caolan/async/issues/1264), [#1271](https://github.com/caolan/async/issues/1271), [#1278](https://github.com/caolan/async/issues/1278), [#1280](https://github.com/caolan/async/issues/1280), [#1282](https://github.com/caolan/async/issues/1282), [#1302](https://github.com/caolan/async/issues/1302))
+
+# v2.0.1
+
+- Significantly optimized all iteration based collection methods such as `each`, `map`, `filter`, etc ([#1245](https://github.com/caolan/async/issues/1245), [#1246](https://github.com/caolan/async/issues/1246), [#1247](https://github.com/caolan/async/issues/1247)).
+
+# v2.0.0
+
+Lots of changes here!
+
+First and foremost, we have a slick new [site for docs](https://caolan.github.io/async/). Special thanks to [**@hargasinski**](https://github.com/hargasinski) for his work converting our old docs to `jsdoc` format and implementing the new website. Also huge ups to [**@ivanseidel**](https://github.com/ivanseidel) for designing our new logo. It was a long process for both of these tasks, but I think these changes turned out extraordinary well.
+
+The biggest feature is modularization. You can now `require("async/series")` to only require the `series` function. Every Async library function is available this way. You still can `require("async")` to require the entire library, like you could do before.
+
+We also provide Async as a collection of ES2015 modules. You can now `import {each} from 'async-es'` or `import waterfall from 'async-es/waterfall'`. If you are using only a few Async functions, and are using a ES bundler such as Rollup, this can significantly lower your build size.
+
+Major thanks to [**@Kikobeats**](github.com/Kikobeats), [**@aearly**](github.com/aearly) and [**@megawac**](github.com/megawac) for doing the majority of the modularization work, as well as [**@jdalton**](github.com/jdalton) and [**@Rich-Harris**](github.com/Rich-Harris) for advisory work on the general modularization strategy.
+
+Another one of the general themes of the 2.0 release is standardization of what an "async" function is. We are now more strictly following the node-style continuation passing style. That is, an async function is a function that:
+
+1. Takes a variable number of arguments
+2. The last argument is always a callback
+3. The callback can accept any number of arguments
+4. The first argument passed to the callback will be treated as an error result, if the argument is truthy
+5. Any number of result arguments can be passed after the "error" argument
+6. The callback is called once and exactly once, either on the same tick or later tick of the JavaScript event loop.
+
+There were several cases where Async accepted some functions that did not strictly have these properties, most notably `auto`, `every`, `some`, `filter`, `reject` and `detect`.
+
+Another theme is performance. We have eliminated internal deferrals in all cases where they make sense. For example, in `waterfall` and `auto`, there was a `setImmediate` between each task -- these deferrals have been removed. A `setImmediate` call can add up to 1ms of delay. This might not seem like a lot, but it can add up if you are using many Async functions in the course of processing a HTTP request, for example. Nearly all asynchronous functions that do I/O already have some sort of deferral built in, so the extra deferral is unnecessary. The trade-off of this change is removing our built-in stack-overflow defense. Many synchronous callback calls in series can quickly overflow the JS call stack. If you do have a function that is sometimes synchronous (calling its callback on the same tick), and are running into stack overflows, wrap it with `async.ensureAsync()`.
+
+Another big performance win has been re-implementing `queue`, `cargo`, and `priorityQueue` with [doubly linked lists](https://en.wikipedia.org/wiki/Doubly_linked_list) instead of arrays. This has lead to queues being an order of [magnitude faster on large sets of tasks](https://github.com/caolan/async/pull/1205).
+
+## New Features
+
+- Async is now modularized. Individual functions can be `require()`d from the main package. (`require('async/auto')`) ([#984](https://github.com/caolan/async/issues/984), [#996](https://github.com/caolan/async/issues/996))
+- Async is also available as a collection of ES2015 modules in the new `async-es` package. (`import {forEachSeries} from 'async-es'`) ([#984](https://github.com/caolan/async/issues/984), [#996](https://github.com/caolan/async/issues/996))
+- Added `race`, analogous to `Promise.race()`. It will run an array of async tasks in parallel and will call its callback with the result of the first task to respond. ([#568](https://github.com/caolan/async/issues/568), [#1038](https://github.com/caolan/async/issues/1038))
+- Collection methods now accept ES2015 iterators.  Maps, Sets, and anything that implements the iterator spec can now be passed directly to `each`, `map`, `parallel`, etc.. ([#579](https://github.com/caolan/async/issues/579), [#839](https://github.com/caolan/async/issues/839), [#1074](https://github.com/caolan/async/issues/1074))
+- Added `mapValues`, for mapping over the properties of an object and returning an object with the same keys. ([#1157](https://github.com/caolan/async/issues/1157), [#1177](https://github.com/caolan/async/issues/1177))
+- Added `timeout`, a wrapper for an async function that will make the task time-out after the specified time. ([#1007](https://github.com/caolan/async/issues/1007), [#1027](https://github.com/caolan/async/issues/1027))
+- Added `reflect` and `reflectAll`, analagous to [`Promise.reflect()`](http://bluebirdjs.com/docs/api/reflect.html), a wrapper for async tasks that always succeeds, by gathering results and errors into an object.  ([#942](https://github.com/caolan/async/issues/942), [#1012](https://github.com/caolan/async/issues/1012), [#1095](https://github.com/caolan/async/issues/1095))
+- `constant` supports dynamic arguments -- it will now always use its last argument as the callback. ([#1016](https://github.com/caolan/async/issues/1016), [#1052](https://github.com/caolan/async/issues/1052))
+- `setImmediate` and `nextTick` now support arguments to partially apply to the deferred function, like the node-native versions do. ([#940](https://github.com/caolan/async/issues/940), [#1053](https://github.com/caolan/async/issues/1053))
+- `auto` now supports resolving cyclic dependencies using [Kahn's algorithm](https://en.wikipedia.org/wiki/Topological_sorting#Kahn.27s_algorithm) ([#1140](https://github.com/caolan/async/issues/1140)).
+- Added `autoInject`, a relative of `auto` that automatically spreads a task's dependencies as arguments to the task function. ([#608](https://github.com/caolan/async/issues/608), [#1055](https://github.com/caolan/async/issues/1055), [#1099](https://github.com/caolan/async/issues/1099), [#1100](https://github.com/caolan/async/issues/1100))
+- You can now limit the concurrency of `auto` tasks. ([#635](https://github.com/caolan/async/issues/635), [#637](https://github.com/caolan/async/issues/637))
+- Added `retryable`, a relative of `retry` that wraps an async function, making it retry when called. ([#1058](https://github.com/caolan/async/issues/1058))
+- `retry` now supports specifying a function that determines the next time interval, useful for exponential backoff, logging and other retry strategies. ([#1161](https://github.com/caolan/async/issues/1161))
+- `retry` will now pass all of the arguments the task function was resolved with to the callback ([#1231](https://github.com/caolan/async/issues/1231)).
+- Added `q.unsaturated` -- callback called when a `queue`'s number of running workers falls below a threshold. ([#868](https://github.com/caolan/async/issues/868), [#1030](https://github.com/caolan/async/issues/1030), [#1033](https://github.com/caolan/async/issues/1033), [#1034](https://github.com/caolan/async/issues/1034))
+- Added `q.error` -- a callback called whenever a `queue` task calls its callback with an error. ([#1170](https://github.com/caolan/async/issues/1170))
+- `applyEach` and `applyEachSeries` now pass results to the final callback. ([#1088](https://github.com/caolan/async/issues/1088))
+
+## Breaking changes
+
+- Calling a callback more than once is considered an error, and an error will be thrown. This had an explicit breaking change in `waterfall`. If you were relying on this behavior, you should more accurately represent your control flow as an event emitter or stream. ([#814](https://github.com/caolan/async/issues/814), [#815](https://github.com/caolan/async/issues/815), [#1048](https://github.com/caolan/async/issues/1048), [#1050](https://github.com/caolan/async/issues/1050))
+- `auto` task functions now always take the callback as the last argument. If a task has dependencies, the `results` object will be passed as the first argument. To migrate old task functions, wrap them with [`_.flip`](https://lodash.com/docs#flip) ([#1036](https://github.com/caolan/async/issues/1036), [#1042](https://github.com/caolan/async/issues/1042))
+- Internal `setImmediate` calls have been refactored away. This may make existing flows vulnerable to stack overflows if you use many synchronous functions in series. Use `ensureAsync` to work around this. ([#696](https://github.com/caolan/async/issues/696), [#704](https://github.com/caolan/async/issues/704), [#1049](https://github.com/caolan/async/issues/1049), [#1050](https://github.com/caolan/async/issues/1050))
+- `map` used to return an object when iterating over an object.  `map` now always returns an array, like in other libraries.  The previous object behavior has been split out into `mapValues`. ([#1157](https://github.com/caolan/async/issues/1157), [#1177](https://github.com/caolan/async/issues/1177))
+- `filter`, `reject`, `some`, `every`, `detect` and their families like `{METHOD}Series` and `{METHOD}Limit` now expect an error as the first callback argument, rather than just a simple boolean. Pass `null` as the first argument, or use `fs.access` instead of `fs.exists`. ([#118](https://github.com/caolan/async/issues/118), [#774](https://github.com/caolan/async/issues/774), [#1028](https://github.com/caolan/async/issues/1028), [#1041](https://github.com/caolan/async/issues/1041))
+- `{METHOD}` and `{METHOD}Series` are now implemented in terms of `{METHOD}Limit`. This is a major internal simplification, and is not expected to cause many problems, but it does subtly affect how functions execute internally. ([#778](https://github.com/caolan/async/issues/778), [#847](https://github.com/caolan/async/issues/847))
+- `retry`'s callback is now optional. Previously, omitting the callback would partially apply the function, meaning it could be passed directly as a task to `series` or `auto`. The partially applied "control-flow" behavior has been separated out into `retryable`. ([#1054](https://github.com/caolan/async/issues/1054), [#1058](https://github.com/caolan/async/issues/1058))
+- The test function for `whilst`, `until`, and `during` used to be passed non-error args from the iteratee function's callback, but this led to weirdness where the first call of the test function would be passed no args. We have made it so the test function is never passed extra arguments, and only the `doWhilst`, `doUntil`, and `doDuring` functions pass iteratee callback arguments to the test function ([#1217](https://github.com/caolan/async/issues/1217), [#1224](https://github.com/caolan/async/issues/1224))
+- The `q.tasks` array has been renamed `q._tasks` and is now implemented as a doubly linked list (DLL). Any code that used to interact with this array will need to be updated to either use the provided helpers or support DLLs ([#1205](https://github.com/caolan/async/issues/1205)).
+- The timing of the `q.saturated()` callback in a `queue` has been modified to better reflect when tasks pushed to the queue will start queueing. ([#724](https://github.com/caolan/async/issues/724), [#1078](https://github.com/caolan/async/issues/1078))
+- Removed `iterator` method in favour of [ES2015 iterator protocol](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Iterators_and_Generators ) which natively supports arrays ([#1237](https://github.com/caolan/async/issues/1237))
+- Dropped support for Component, Jam, SPM, and Volo ([#1175](https://github.com/caolan/async/issues/1175), #[#176](https://github.com/caolan/async/issues/176))
+
+## Bug Fixes
+
+- Improved handling of no dependency cases in `auto` & `autoInject` ([#1147](https://github.com/caolan/async/issues/1147)).
+- Fixed a bug where the callback generated by `asyncify` with  `Promises` could resolve twice ([#1197](https://github.com/caolan/async/issues/1197)).
+- Fixed several documented optional callbacks not actually being optional ([#1223](https://github.com/caolan/async/issues/1223)).
+
+## Other
+
+- Added `someSeries` and `everySeries` for symmetry, as well as a complete set of `any`/`anyLimit`/`anySeries` and `all`/`/allLmit`/`allSeries` aliases.
+- Added `find` as an alias for `detect. (as well as `findLimit` and `findSeries`).
+- Various doc fixes ([#1005](https://github.com/caolan/async/issues/1005), [#1008](https://github.com/caolan/async/issues/1008), [#1010](https://github.com/caolan/async/issues/1010), [#1015](https://github.com/caolan/async/issues/1015), [#1021](https://github.com/caolan/async/issues/1021), [#1037](https://github.com/caolan/async/issues/1037), [#1039](https://github.com/caolan/async/issues/1039), [#1051](https://github.com/caolan/async/issues/1051), [#1102](https://github.com/caolan/async/issues/1102), [#1107](https://github.com/caolan/async/issues/1107), [#1121](https://github.com/caolan/async/issues/1121), [#1123](https://github.com/caolan/async/issues/1123), [#1129](https://github.com/caolan/async/issues/1129), [#1135](https://github.com/caolan/async/issues/1135), [#1138](https://github.com/caolan/async/issues/1138), [#1141](https://github.com/caolan/async/issues/1141), [#1153](https://github.com/caolan/async/issues/1153), [#1216](https://github.com/caolan/async/issues/1216), [#1217](https://github.com/caolan/async/issues/1217), [#1232](https://github.com/caolan/async/issues/1232), [#1233](https://github.com/caolan/async/issues/1233), [#1236](https://github.com/caolan/async/issues/1236), [#1238](https://github.com/caolan/async/issues/1238))
+
+Thank you [**@aearly**](github.com/aearly) and [**@megawac**](github.com/megawac) for taking the lead on version 2 of async.

+
+- Added `transform`, analogous to [`_.transform`](http://lodash.com/docs#transform) ([#892](https://github.com/caolan/async/issues/892))
+- `map` now returns an object when an object is passed in, rather than array with non-numeric keys. `map` will begin always returning an array with numeric indexes in the next major release. ([#873](https://github.com/caolan/async/issues/873))
+- `auto` now accepts an optional `concurrency` argument to limit the number o. running tasks ([#637](https://github.com/caolan/async/issues/637))
+- Added `queue#workersList()`, to retrieve the lis. of currently running tasks. ([#891](https://github.com/caolan/async/issues/891))

+
+# v1.4.1
+
+- Add in overlooked `detectLimit` method ([#866](https://github.com/caolan/async/issues/866))
+- Removed unnecessary files from npm releases ([#861](https://github.com/caolan/async/issues/861))

+
+# v1.4.0
+
+- `asyncify` now supports promises ([#840](https://github.com/caolan/async/issues/840))
+- Added `Limit` versions of `filter` and `reject` ([#836](https://github.com/caolan/async/issues/836))

+- `during` now gets called with arguments from iterator ([#824](https://github.com/caolan/async/issues/824))
+- Code simplifications and optimizations aplenty ([diff](https://github.com/caolan/async/compare/v1.3.0...v1.4.0))
+
+
+# v1.3.0
+
+New Features:
+- Added `constant`
+- Added `asyncify`/`wrapSync` for making sync functions work with callbacks. ([#671](https://github.com/caolan/async/issues/671), [#806](https://github.com/caolan/async/issues/806))
+- Added `during` and `doDuring`, which are like `whilst` with an async truth test. ([#800](https://github.com/caolan/async/issues/800))
+- `retry` now accepts an `interval` parameter to specify a delay between retries. ([#793](https://github.com/caolan/async/issues/793))
+- `async` should work better in Web Workers due to better `root` detection ([#804](https://github.com/caolan/async/issues/804))
+- Callbacks are now optional in `whilst`, `doWhilst`, `until`, and `doUntil` ([#642](https://github.com/caolan/async/issues/642))
+- Various internal updates ([#786](https://github.com/caolan/async/issues/786), [#801](https://github.com/caolan/async/issues/801), [#802](https://github.com/caolan/async/issues/802), [#803](https://github.com/caolan/async/issues/803))
+- Various doc fixes ([#790](https://github.com/caolan/async/issues/790), [#794](https://github.com/caolan/async/issues/794))
+
+Bug Fixes:
+- `cargo` now exposes the `payload` size, and `cargo.payload` can be changed on the fly after the `cargo` is created. ([#740](https://github.com/caolan/async/issues/740), [#744](https://github.com/caolan/async/issues/744), [#783](https://github.com/caolan/async/issues/783))
+
+
+# v1.2.1
+
+Bug Fix:
+
+- Small regression with synchronous iterator behavior in `eachSeries` with a 1-element array. Before 1.1.0, `eachSeries`'s callback was called on the same tick, which this patch restores. In 2.0.0, it will be called on the next tick. ([#782](https://github.com/caolan/async/issues/782))
+
+
+# v1.2.0
+
+New Features:
+
+- Added `timesLimit` ([#743](https://github.com/caolan/async/issues/743))
+- `concurrency` can be changed after initialization in `queue` by setting `q.concurrency`. The new concurrency will be reflected the next time a task is processed. ([#747](https://github.com/caolan/async/issues/747), [#772](https://github.com/caolan/async/issues/772))
+
+Bug Fixes:
+
+- Fixed a regression in `each` and family with empty arrays that have additional properties. ([#775](https://github.com/caolan/async/issues/775), [#777](https://github.com/caolan/async/issues/777))
+
+
+# v1.1.1
+
+Bug Fix:
+
+- Small regression with synchronous iterator behavior in `eachSeries` with a 1-element array. Before 1.1.0, `eachSeries`'s callback was called on the same tick, which this patch restores. In 2.0.0, it will be called on the next tick. ([#782](https://github.com/caolan/async/issues/782))
+
+
+# v1.1.0
+
+New Features:
+
+- `cargo` now supports all of the same methods and event callbacks as `queue`.
+- Added `ensureAsync` - A wrapper that ensures an async function calls its callback on a later tick. ([#769](https://github.com/caolan/async/issues/769))
+- Optimized `map`, `eachOf`, and `waterfall` families of functions
+- Passing a `null` or `undefined` array to `map`, `each`, `parallel` and families will be treated as an empty array ([#667](https://github.com/caolan/async/issues/667)).
+- The callback is now optional for the composed results of `compose` and `seq`. ([#618](https://github.com/caolan/async/issues/618))
+- Reduced file size by 4kb, (minified version by 1kb)
+- Added code coverage through `nyc` and `coveralls` ([#768](https://github.com/caolan/async/issues/768))
+
+Bug Fixes:
+
+- `forever` will no longer stack overflow with a synchronous iterator ([#622](https://github.com/caolan/async/issues/622))
+- `eachLimit` and other limit functions will stop iterating once an error occurs ([#754](https://github.com/caolan/async/issues/754))
+- Always pass `null` in callbacks when there is no error ([#439](https://github.com/caolan/async/issues/439))
+- Ensure proper conditions when calling `drain()` after pushing an empty data set to a queue ([#668](https://github.com/caolan/async/issues/668))
+- `each` and family will properly handle an empty array ([#578](https://github.com/caolan/async/issues/578))
+- `eachSeries` and family will finish if the underlying array is modified during execution ([#557](https://github.com/caolan/async/issues/557))
+- `queue` will throw if a non-function is passed to `q.push()` ([#593](https://github.com/caolan/async/issues/593))
+- Doc fixes ([#629](https://github.com/caolan/async/issues/629), [#766](https://github.com/caolan/async/issues/766))
+
+
+# v1.0.0
+
+No known breaking changes, we are simply complying with semver from here on out.
+
+Changes:
+
+- Start using a changelog!
+- Add `forEachOf` for iterating over Objects (or to iterate Arrays with indexes available) ([#168](https://github.com/caolan/async/issues/168) [#704](https://github.com/caolan/async/issues/704) [#321](https://github.com/caolan/async/issues/321))
+- Detect deadlocks in `auto` ([#663](https://github.com/caolan/async/issues/663))
+- Better support for require.js ([#527](https://github.com/caolan/async/issues/527))

+- Fix unneeded iteration in `queue.resume()` ([#758](https://github.com/caolan/async/issues/758))
+- Guard against timer mocking overriding `setImmediate` ([#609](https://github.com/caolan/async/issues/609) [#611](https://github.com/caolan/async/issues/611))
+- Miscellaneous doc fixes ([#542](https://github.com/caolan/async/issues/542) [#596](https://github.com/caolan/async/issues/596) [#615](https://github.com/caolan/async/issues/615) [#628](https://github.com/caolan/async/issues/628) [#631](https://github.com/caolan/async/issues/631) [#690](https://github.com/caolan/async/issues/690) [#729](https://github.com/caolan/async/issues/729))
+- Use single noop function internally ([#546](https://github.com/caolan/async/issues/546))
+- Optimize internal `_each`, `_map` and `_keys` functions.

+
+Async is a utility module which provides straight-forward, powerful functions for working with [asynchronous JavaScript](http://caolan.github.io/async/global.html). Although originally designed for use with [Node.js](https://nodejs.org/) and installable via `npm install --save async`, it can also be used directly in the browser.
+
+This version of the package is optimized for the Node.js environment. If you use Async with webpack, install [`async-es`](https://www.npmjs.com/package/async-es) instead.
+

+
+```javascript
+// for use with Node-style callbacks...
+var async = require("async");
+
+var obj = {dev: "/dev.json", test: "/test.json", prod: "/prod.json"};
+var configs = {};
+

+ * * a `callback(err, result)` function, which must be called when finished,

+ * A dependency-injected version of the [async.auto]{@link module:ControlFlow.auto} function. Dependent
+ * tasks are specified as parameters to the function, after the usual callback
+ * parameter, with the parameter names matching the names of the tasks it
+ * depends on. This can provide even more readable task graphs which can be
+ * easier to maintain.
+ *
+ * If a final callback is specified, the task results are similarly injected,
+ * specified as named parameters after the initial error parameter.
+ *
+ * The autoInject function is purely syntactic sugar and its semantics are
+ * otherwise equivalent to [async.auto]{@link module:ControlFlow.auto}.
+ *
+ * @name autoInject
+ * @static
+ * @memberOf module:ControlFlow
+ * @method
+ * @see [async.auto]{@link module:ControlFlow.auto}
+ * @category Control Flow
+ * @param {Object} tasks - An object, each of whose properties is an {@link AsyncFunction} of
+ * the form 'func([dependencies...], callback). The object's key of a property
+ * serves as the name of the task defined by that property, i.e. can be used
+ * when specifying requirements for other tasks.
+ * * The `callback` parameter is a `callback(err, result)` which must be called
+ *   when finished, passing an `error` (which can be `null`) and the result of
+ *   the function's execution. The remaining parameters name other tasks on
+ *   which the task is dependent, and the results from those tasks are the
+ *   arguments of those parameters.
+ * @param {Function} [callback] - An optional callback which is called when all
+ * the tasks have been completed. It receives the `err` argument if any `tasks`
+ * pass an error to their callback, and a `results` object with any completed
+ * task results, similar to `auto`.
+ * @example
+ *
+ * //  The example from `auto` can be rewritten as follows:
+ * async.autoInject({
+ *     get_data: function(callback) {
+ *         // async code to get some data
+ *         callback(null, 'data', 'converted to array');
+ *     },
+ *     make_folder: function(callback) {
+ *         // async code to create a directory to store a file in
+ *         // this is run at the same time as getting the data
+ *         callback(null, 'folder');
+ *     },
+ *     write_file: function(get_data, make_folder, callback) {
+ *         // once there is some data and the directory exists,
+ *         // write the data to a file in the directory
+ *         callback(null, 'filename');
+ *     },
+ *     email_link: function(write_file, callback) {
+ *         // once the file is written let's email a link to it...
+ *         // write_file contains the filename returned by write_file.
+ *         callback(null, {'file':write_file, 'email':'user@example.com'});

+ * }, function(err, results) {
+ *     console.log('err = ', err);
+ *     console.log('email_link = ', results.email_link);
+ * });
+ *
+ * // If you are using a JS minifier that mangles parameter names, `autoInject`
+ * // will not work with plain functions, since the parameter names will be
+ * // collapsed to a single letter identifier.  To work around this, you can
+ * // explicitly specify the names of the parameters your task function needs
+ * // in an array, similar to Angular.js dependency injection.
+ *
+ * // This still has an advantage over plain `auto`, since the results a task
+ * // depends on are still spread into arguments.

+ * easier to maintain.
+ *
+ * If a final callback is specified, the task results are similarly injected,
+ * specified as named parameters after the initial error parameter.
+ *
+ * The autoInject function is purely syntactic sugar and its semantics are
+ * otherwise equivalent to [async.auto]{@link module:ControlFlow.auto}.
+ *
+ * @name autoInject
+ * @static

+ * @category Control Flow
+ * @param {Object} tasks - An object, each of whose properties is an {@link AsyncFunction} of
+ * the form 'func([dependencies...], callback). The object's key of a property
+ * serves as the name of the task defined by that property, i.e. can be used
+ * when specifying requirements for other tasks.
+ * * The `callback` parameter is a `callback(err, result)` which must be called
+ *   when finished, passing an `error` (which can be `null`) and the result of
+ *   the function's execution. The remaining parameters name other tasks on
+ *   which the task is dependent, and the results from those tasks are the
+ *   arguments of those parameters.
+ * @param {Function} [callback] - An optional callback which is called when all
+ * the tasks have been completed. It receives the `err` argument if any `tasks`
+ * pass an error to their callback, and a `results` object with any completed
+ * task results, similar to `auto`.
+ * @example
+ *
+ * //  The example from `auto` can be rewritten as follows:
+ * async.autoInject({
+ *     get_data: function(callback) {
+ *         // async code to get some data
+ *         callback(null, 'data', 'converted to array');

+ *     make_folder: function(callback) {
+ *         // async code to create a directory to store a file in
+ *         // this is run at the same time as getting the data
+ *         callback(null, 'folder');
+ *     },
+ *     write_file: function(get_data, make_folder, callback) {
+ *         // once there is some data and the directory exists,
+ *         // write the data to a file in the directory
+ *         callback(null, 'filename');
+ *     },
+ *     email_link: function(write_file, callback) {
+ *         // once the file is written let's email a link to it...
+ *         // write_file contains the filename returned by write_file.
+ *         callback(null, {'file':write_file, 'email':'user@example.com'});
+ *     }
+ * }, function(err, results) {
+ *     console.log('err = ', err);
+ *     console.log('email_link = ', results.email_link);
+ * });
+ *
+ * // If you are using a JS minifier that mangles parameter names, `autoInject`
+ * // will not work with plain functions, since the parameter names will be
+ * // collapsed to a single letter identifier.  To work around this, you can
+ * // explicitly specify the names of the parameters your task function needs
+ * // in an array, similar to Angular.js dependency injection.
+ *
+ * // This still has an advantage over plain `auto`, since the results a task
+ * // depends on are still spread into arguments.

+/**
+ * An "async function" in the context of Async is an asynchronous function with
+ * a variable number of parameters, with the final parameter being a callback.
+ * (`function (arg1, arg2, ..., callback) {}`)
+ * The final callback is of the form `callback(err, results...)`, which must be
+ * called once the function is completed.  The callback should be called with a
+ * Error as its first argument to signal that an error occurred.
+ * Otherwise, if no error occurred, it should be called with `null` as the first
+ * argument, and any additional `result` arguments that may apply, to signal
+ * successful completion.
+ * The callback must be called exactly once, ideally on a later tick of the
+ * JavaScript event loop.
+ *
+ * This type of function is also referred to as a "Node-style async function",
+ * or a "continuation passing-style function" (CPS). Most of the methods of this
+ * library are themselves CPS/Node-style async functions, or functions that
+ * return CPS/Node-style async functions.
+ *
+ * Wherever we accept a Node-style async function, we also directly accept an
+ * [ES2017 `async` function]{@link https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function}.
+ * In this case, the `async` function will not be passed a final callback
+ * argument, and any thrown error will be used as the `err` argument of the
+ * implicit callback, and the return value will be used as the `result` value.
+ * (i.e. a `rejected` of the returned Promise becomes the `err` callback
+ * argument, and a `resolved` value becomes the `result`.)
+ *
+ * Note, due to JavaScript limitations, we can only detect native `async`
+ * functions and not transpilied implementations.
+ * Your environment must have `async`/`await` support for this to work.
+ * (e.g. Node > v7.6, or a recent version of a modern browser).
+ * If you are using `async` functions through a transpiler (e.g. Babel), you
+ * must still wrap the function with [asyncify]{@link module:Utils.asyncify},
+ * because the `async function` will be compiled to an ordinary function that
+ * returns a promise.
+ *

+    * An "async function" in the context of Async is an asynchronous function with
+    * a variable number of parameters, with the final parameter being a callback.
+    * (`function (arg1, arg2, ..., callback) {}`)
+    * The final callback is of the form `callback(err, results...)`, which must be
+    * called once the function is completed.  The callback should be called with a
+    * Error as its first argument to signal that an error occurred.
+    * Otherwise, if no error occurred, it should be called with `null` as the first
+    * argument, and any additional `result` arguments that may apply, to signal
+    * successful completion.
+    * The callback must be called exactly once, ideally on a later tick of the
+    * JavaScript event loop.
+    *
+    * This type of function is also referred to as a "Node-style async function",
+    * or a "continuation passing-style function" (CPS). Most of the methods of this
+    * library are themselves CPS/Node-style async functions, or functions that
+    * return CPS/Node-style async functions.
+    *
+    * Wherever we accept a Node-style async function, we also directly accept an
+    * [ES2017 `async` function]{@link https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function}.
+    * In this case, the `async` function will not be passed a final callback
+    * argument, and any thrown error will be used as the `err` argument of the
+    * implicit callback, and the return value will be used as the `result` value.
+    * (i.e. a `rejected` of the returned Promise becomes the `err` callback
+    * argument, and a `resolved` value becomes the `result`.)
+    *
+    * Note, due to JavaScript limitations, we can only detect native `async`
+    * functions and not transpilied implementations.
+    * Your environment must have `async`/`await` support for this to work.
+    * (e.g. Node > v7.6, or a recent version of a modern browser).
+    * If you are using `async` functions through a transpiler (e.g. Babel), you
+    * must still wrap the function with [asyncify]{@link module:Utils.asyncify},
+    * because the `async function` will be compiled to an ordinary function that
+    * returns a promise.

+ * **Hint:** Use [`reflect`]{@link module:Utils.reflect} to continue the
