/* Inspired from http://tutsplus.com/lesson/custom-events-and-the-observer-pattern/ */


(function( $ ) {
	var o = $( {} );

	$.each({
		trigger: 'publish',
		on: 'subscribe',
		off: 'unsubscribe'
	}, function( key, val ) {
		jQuery[val] = function() {
			o[key].apply( o, arguments);
		};
	});
})( jQuery );


/* Usage */

$.getJSON('http:/search.twitter.com/search.json?q=dogs&callback=?', function( results ) {
	$.publish( 'twitter/results', results );
});

// ...

$.subscribe( 'twitter/results', function( e, results ) {
	// console.log(results);
	$('body').html(
		$.map( results.results, function( obj, index ) {
			return '<li>' + obj.text + '</li>';
		}).join('')
	);
});
