/**
* The SSViewer executes a . ss template file .
* The SSViewer class handles rendering of . ss templates . In addition to a full template in
* the views folder , a template in views / Content or views / Layout will be rendered into $Content and
* $Layout , respectively .
*
* Compiled templates are cached . If you put ? flush = 1 on your URL , it will force the template to be recompiled . This
* is a hack ; the system should really detect when a page needs re - fetching .
2008-10-06 21:25:45 +02:00
*
* Works with the global $_TEMPLATE_MANIFEST which is compiled by { @ link ManifestBuilder -> getTemplateManifest ()} .
* This associative array lists all template filepaths by " identifier " , meaning the name
* of the template without its path or extension .
*
* Example :
* < code >
* array (
* 'LeftAndMain' =>
* array (
* 'main' => '/my/system/path/cms/templates/LeftAndMain.ss' ,
* ),
* 'CMSMain_left' =>
* array (
* 'Includes' => '/my/system/path/cms/templates/Includes/CMSMain_left.ss' ,
* ),
* 'Page' =>
* array (
* 'themes' =>
* array (
* 'blackcandy' =>
* array (
* 'Layout' => '/my/system/path/themes/blackcandy/templates/Layout/Page.ss' ,
* 'main' => '/my/system/path/themes/blackcandy/templates/Page.ss' ,
* ),
* 'blue' =>
* array (
* 'Layout' => '/my/system/path/themes/mysite/templates/Layout/Page.ss' ,
* 'main' => '/my/system/path/themes/mysite/templates/Page.ss' ,
* ),
* ),
* ),
* // ...
* )
* </ code >
