Usage

See Twig syntax.
Current controller properties are accessible via {{this.pageTitle}}.
Yii::app() object is accessible via {{App}}.
Yii's core static classes (for example, CHtml) are accessible via {{C.ClassNameWithoutFirstC.Method}} (example: {{C.Html.textField(name,'value')}})
To call functions or methods which return non-string result wrap these calls with 'void' function: {{void(App.clientScript.registerScriptFile(...))}}

Widgets usage example

<div id="mainmenu">
    {{ this.widget('zii.widgets.CMenu',{
        'items':[
            {'label':'Home', 'url':['/site/index']},
            {'label':'About', 'url':{0:'/site/page', 'view':'about'} },
            {'label':'Contact', 'url':['/site/contact']},
            {'label':'Login', 'url':['/site/login'], 'visible':App.user.isGuest},
            {'label':'Logout ('~App.user.name~')', 'url':['/site/logout'], 'visible':not App.user.isGuest}
        ]
    }, true) }}
</div><!-- mainmenu -->
