Includejs

Allows you to inject functions and properties from other JavaScript objects into your current object. This is similar to the functionality provided by _.extend in the Underscore.js library, the difference being that Includejs will bind the functions to the current object, helpful well dealing with callback functions.

Installation

Ruby/Rails

Add this line to your application's Gemfile:

gem 'includejs'

And then execute:

$ bundle

Or install it yourself as:

$ gem install includejs

Rails

Require includejs in your asset pipeline and you're ready to go.

Non-Rails

To use this outside of a Rails application simply copy the vendor/assets/javascripts/includejs.js file and add it to your application. That's it.

Usage

CoffeeScript Example:

BazModule =
  sayHi: ->
    "Hello #{@name}!"
  # If there is an 'included' function it will
  # be called when the module is included.
  included: (klass) ->
    klass.baz = "Baz!!"

class Foo
  constructor: ->
    include(@, BazModule)

foo = new Foo()
foo.sayHi() # => "Hello undefined!"

foo.name = "Mark"
foo.sayHi() # => "Hello Mark!"

JavaScript Example:

var BazModule, foo;

BazModule = {
  sayHi: function() {
    return "Hello " + this.name + "!";
  },
  // If there is an 'included' function it will
  // be called when the module is included.
  included: function(klass) {
    klass.baz = "Baz!!";
  }
};

foo = {}
include(foo, BazModule);

foo.sayHi(); // => "Hello undefined!"

foo.name = "Mark";

foo.sayHi(); // => "Hello Mark!"
