Extractor.js

Extractor is a tiny JavaScript library for managing variables in the global namespace. Instead of attaching themselves to the global object, libraries may register with Extractor. Developers can then retrieve registered libraries from Extractor and assign them to a variable of their choice. It achieves an effect similar to jQuery's noConflict function with CommonJS terminology.

Usage

For library authors:

// Assuming Extractor.js has been included

(function () {
  var MyLibrary = {
    foo: "bar"
  };

  Extractor.exports("MyLibrary", MyLibrary);
})();

For developers:

Extracting a library

var FooBar = Extractor.require("MyLibrary");

Extracting a single property/function from a library

var barify = Extractor.extract("MyLibrary").fooify;

This allows developers to extract any module (or any property of a module) into a variable with a name of their choosing.

Listing registered modules

To get an alphabetical list of the names of all modules registered with Extractor, call Extractor.listModules().

Resetting Extractor's registry

If, for some reason, you need to programmatically reset Extractor's registry, call Extractor.reset() to clear all registered modules.

Development

To work on Extractor or to run the included Jasmine specs, you must have Node and NPM installed. Clone the repository and run npm install inside the directory to install the Node dependencies. You should also install CoffeeScript globally with npm install coffee-script -g to get command line access to the Cake tasks. Run cake for a list of available tasks.
