Monkey patch for require in Titanium Mobile

app.js

/*
add a monkey-patched "require" function to the global scope (global object).
It is smarter in two ways:
- It only loads a module once
- If the exports object contains a function matching the module base name, return that
  value from "require" - this is a bit of sugar added because Titanium's require implementation
  does not allow you to replace the "exports" object directly
*/

//monkey patch "require" in the global scope
require('require_patch').monkeypatch(this);

//regular modules are the same...
var module = require('module');
module.sayHello('Marshall');
module.sayGoodbye('Kevin');

//modules which contain a type by the same name as the module...
var Person = require('Person');
var jedi = new Person('Luke','Skywalker');

module.js

exports.sayHello = function(name) {
    alert('Hello '+name+'!');
};

exports.sayGoodbye = function(name) {
    alert('Goodbye '+name+'!');
};

Person.js

exports.Person = function(firstName,lastName) {
    this.firstName = firstName;
    this.lastName = lastName;
};

require_patch.js

exports.monkeypatch = function(object) {
	var scriptRegistry = {},
		old_require = object.require;
	object.require = function(moduleName) {
		if (!scriptRegistry[moduleName]) {
			var mod = old_require(moduleName),
				moduleRoot = moduleName.split(/[\/ ]+/).pop();
			if (typeof(mod[moduleRoot]) === 'function') {
				scriptRegistry[moduleName] = mod[moduleRoot];
			}
			else {
				scriptRegistry[moduleName] = mod;
			}	
		}
		return scriptRegistry[moduleName];
	};
};
