// `Sammy.Template` 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):
//
// // 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:
//
// // app.js
// $.sammy(function() {
// // include the plugin
// this.use('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');
// });
//
// By default, the data passed into the tempalate is passed automatically passed through
// Sammy's `escapeHTML` method in order to prevent possible XSS attacks. This is
// a problem though if you're using something like `Sammy.Form` which renders HTML
// within the templates. You can get around this in two ways. One, you can use the
// `<%! %>` instead of `<%= %>`. Two, you can pass the `escape_html = false` option
// when interpolating, i.e:
//
// this.get('#/', function() {
// this.template('myform.tpl', {form: "<form></form>"}, {escape_html: false});
// });
//
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.
//
var template = function(template, data, name, options) {
// use name for caching
if (typeof name == 'undefined') { name = template; }
if (typeof options == 'undefined' && typeof name == 'object') {
options = name; name = template;
}
return srender(name, template, $.extend({h: _escapeHTML}, this, data), options);
};
// set the default method name/extension
if (!method_alias) { method_alias = 'template'; }
// create the helper at the method alias
app.helper(method_alias, template);
};
return Sammy.Template;
