Download the PHP package apex/syrus without Composer

Syrus Template Engine

A light weight, extensible template engine designed with separation of duties in mind, allowing both back-end developers and designers to complete their work independently. It supports:

• Standardized <s:...) template tags providing short hand for larger HTML snippets, interopability across themes, plus additional PHP functionality.
• Easily develop your own functional template tags in addition to default set.
• Easy loading of dynamic content such as breadcrumbs, social media links, and placeholders.
• Multiple themes based on template file location (eg. different themes for public site, admin panel, and client area).
• PSR6 caching, including configuration for no-cache pages and tags, and support for optional "cache" attribute within tags.
• Optional auto-routing, automatically renders the appropriate template corresponding to the URI being viewed.
• Optional per-template PHP class, which is automatically executed upon rendering the template providing bridge between templates and back-end application.
• Developed with designers in mind, allowing them to work independently and without the need to navigate back-end software code.
• Built-in support for Cluster, which makes an RPC call for every template rendered providing support for horizontal scaling including parameter based routing.
• Optional built-in support for Apex Debugger to gather debugging information on templates rendered.

    'province' => 'Ontario', 
    'country' => 'Canada'
];
$syrus->assign('loc', $location);

// Add foreach blocks
$syrus->addBlock('users', ['username' => 'jsmith', 'email' => '[email protected]']);
$syrus->addBlock('users', ['username' => 'mike', 'email' => '[email protected]']);

// ADd error callout
$this->addCallout('Uh oh, there was a problem.', 'error');

// Render template
echo $syrus->render('contact.html');

// Or, use auto-routing and render template based on URI being viewed.
echo $syrus->render();
