// <tt>Sammy</tt> (also aliased as $.sammy) is not only the namespace for a
// number of prototypes, its also a top level method that allows for easy
// creation/management of <tt>Sammy.Application</tt> instances. There are a
// number of different forms for <tt>Sammy()</tt> but each returns an instance
// of <tt>Sammy.Application</tt>. When a new instance is created using
// <tt>Sammy</tt> it is added to an Object called <tt>Sammy.apps</tt>. This
// provides for an easy way to get at existing Sammy applications. Only one
// instance is allowed per <tt>element_selector</tt> so when calling
// <tt>Sammy('selector')</tt> multiple times, the first time will create
// the application and the following times will extend the application
// already added to that selector.
//
// === Example
//
// // returns the app at #main or a new app
// Sammy('#main')
//
// // equivilent to "new Sammy.Application", except appends to apps
// Sammy();

//

// The HashLocationProxy is the default location proxy for all Sammy applications.

// changed when the 'hash' (window.location.hash / '#') changes. It does this in two
// different ways depending on what browser you are using. The newest browsers
// (IE, Safari > 4, FF >= 3.6) support a 'onhashchange' DOM event, thats fired whenever
// the location.hash changes. In this situation the HashLocationProxy just binds
// to this event and delegates it to the application. In the case of older browsers

// <tt>Sammy.EventContext</tt> objects are created every time a route is run or a
// bound event is triggered. The callbacks for these events are evaluated within a <tt>Sammy.EventContext</tt>
// This within these callbacks the special methods of <tt>EventContext</tt> are available.
//
// === Example
//
// $.sammy(function() { with(this) {
// // The context here is this Sammy.Application
// get('#/:name', function() { with(this) {
// // The context here is a new Sammy.EventContext
// if (params['name'] == 'sammy') {
// partial('name.html.erb', {name: 'Sammy'});
// } else {
// redirect('#/somewhere-else')
// }
// }});
// }});
//
// Initialize a new EventContext
//
// === Arguments
//
// +app+:: The <tt>Sammy.Application</tt> this event is called within.
// +verb+:: The verb invoked to run this context/route.
// +path+:: The string path invoked to run this context/route.
// +params+:: An Object of optional params to pass to the context. Is converted
// to a <tt>Sammy.Object</tt>.

// A shortcut to the app's <tt>$element()</tt>

// Used for rendering remote templates or documents within the current application/DOM.
// By default Sammy and <tt>partial()</tt> know nothing about how your templates
// should be interpeted/rendered. This is easy to change, though. <tt>partial()</tt> looks
// for a method in <tt>EventContext</tt> that matches the extension of the file you're
// fetching (e.g. 'myfile.template' will look for a template() method, 'myfile.haml' => haml(), etc.)
// If no matching render method is found it just takes the file contents as is.
//
// If you're templates have different (or no) extensions, and you want to render them all
// through the same engine, you can set the default/fallback template engine on the app level
// by setting <tt>app.template_engine</tt> to the name of the engine or a <tt>function() {}</tt>
//
// === Caching
//
// If you use the <tt>Sammy.Cache</tt> plugin, remote requests will be automatically cached unless
// you explicitly set <tt>cache_partials</tt> to <tt>false</tt>
//
// === Example
//
// There are a couple different ways to use <tt>partial()</tt>:
//
// partial('doc.html');
// //=> Replaces $element() with the contents of doc.html
//
// use(Sammy.Template);
// //=> includes the template() method
// partial('doc.template', {name: 'Sammy'});
// //=> Replaces $element() with the contents of doc.template run through <tt>template()</tt>
//
// partial('doc.html', function(data) {
// // data is the contents of the template.
// $('.other-selector').html(data);
// });
//
// === Iteration/Arrays
//
// If the data object passed to <tt>partial()</tt> is an Array, <tt>partial()</tt>
// will itterate over each element in data calling the callback with the
// results of interpolation and the index of the element in the array.
//
// use(Sammy.Template);
// // item.template => "<li>I'm an item named <%= name %></li>"
// partial('item.template', [{name: "Item 1"}, {name: "Item 2"}])
// //=> Replaces $element() with:
// // <li>I'm an item named Item 1</li><li>I'm an item named Item 2</li>
// partial('item.template', [{name: "Item 1"}, {name: "Item 2"}], function(rendered, i) {
// rendered; //=> <li>I'm an item named Item 1</li> // for each element in the Array
// i; // the 0 based index of the itteration
// });

// <tt>Sammy.Template</tt> is a simple plugin that provides a way to create
// and render client side templates. The rendering code is based on John Resig's
// quick templates and Greg Borenstien's srender plugin.
// This is also a great template/boilerplate for Sammy plugins.
//
// Templates use <% %> tags to denote embedded javascript.
//
// === Examples
//
// Here is an example template (user.template):
//
// <div class="user">
// <div class="user-name"><%= user.name %></div>
// <% if (user.photo_url) { %>
// <div class="photo"><img src="<%= user.photo_url %>" /></div>
// <% } %>
// </div>
//
// Given that is a publicly accesible file, you would render it like:
//
// $.sammy(function() {
// // include the plugin
// this.use(Sammy.Template);
//
// this.get('#/', function() {
// // the template is rendered in the current context.
// this.user = {name: 'Aaron Quint'};
// // partial calls template() because of the file extension
// this.partial('user.template');
// })
// });
//
// You can also pass a second argument to use() that will alias the template
// method and therefore allow you to use a different extension for template files
// in <tt>partial()</tt>
//
// // alias to 'tpl'
// this.use(Sammy.Template, 'tpl');
//
// // now .tpl files will be run through srender
// this.get('#/', function() {
// this.partial('myfile.tpl');
// });
//
Sammy.Template = function(app, method_alias) {
// *Helper:* Uses simple templating to parse ERB like templates.
//
// === Arguments
//
// +template+:: A String template. '<% %>' tags are evaluated as Javascript and replaced with the elements in data.
// +data+:: An Object containing the replacement values for the template.
// data is extended with the <tt>EventContext</tt> allowing you to call its methods within the template.
// +name+:: An optional String name to cache the template.
//
