control.async

Operations for asynchronous control flow.

Example

var fs    = require('fs')
var async = require('control.async')

var read = async.liftNode(fs.readFile)

var files = async.parallel( read('foo.txt', 'utf-8')
                          , read('bar.txt', 'utf-8')
                          , read('baz.txt', 'utf-8'))

var concatenated = files.chain(function(xs){ return xs.join('') })

// Futures are pure, so you need to actually run the action to get
// the effects.
concatenated.fork(
  function(error){ throw error }
, function(value){ console.log(value) }
)

Installing

The easiest way is to grab it from NPM. If you're running in a Browser environment, you can use Browserify

$ npm install control.async

Using with CommonJS

If you're not using NPM, Download the latest release, and require the control.async.umd.js file:

var Async = require('control.async')

Using with AMD

Download the latest release, and require the control.async.umd.js file:

require(['control.async'], function(Async) {
  ( ... )
})

Using without modules

Download the latest release, and load the control.async.umd.js file. The properties are exposed in the global Async object:

<script src="/path/to/control.async.umd.js"></script>

Compiling from source

If you want to compile this library from the source, you'll need Git, Make, Node.js, and run the following commands:

$ git clone git://github.com/folktale/control.async.git
$ cd control.async
$ npm install
$ make bundle

This will generate the dist/control.async.umd.js file, which you can load in any JavaScript environment.

Documentation

You can read the documentation online or build it yourself:

$ git clone git://github.com/folktale/control.async.git
$ cd control.async
$ npm install
$ make documentation

Then open the file docs/index.html in your browser.

Platform support

This library assumes an ES5 environment, but can be easily supported in ES3 platforms by the use of shims. Just include es5-shim :)
