TemplateEngineMustache

License: MIT ProcessWire 3

A ProcessWire module adding Mustache to the TemplateEngineFactory.

Requirements


  • ProcessWire 3.0 or newer
  • TemplateEngineFactory 2.0 or newer
  • PHP 7.0 or newer
  • Composer

The 1.x version of this module is available on the 1.x branch. Use this version if you still use TemplateEngineFactory 1.x.

Installation


Execute the following command in the root directory of your ProcessWire installation:

composer require blue-tomato/template-engine-mustache:^2.0

This will install the TemplateEngineMustache and TemplateEngineFactory modules in one step. Afterwards, don't forget to enable Mustache as engine in the TemplateEngineFactory module's configuration.

This module includes test dependencies. If you are installing on production with composer install, make sure to pass the --no-dev flag to omit autoloading any unnecessary test dependencies!.

Configuration


The module offers the following configuration:

  • Template files suffix The suffix of the Twig template files, defaults to mustache.
  • Provide ProcessWire API variables in Mustache templates API variables ($pages, $input, $config...) are accessible in Twig, e.g. {{ config }} for the config API variable.
  • Debug If enabled, Mustache outputs debug information.

Extending Mustache


It is possible to extend Mustache after it has been initialized by the module. Hook the method TemplateEngineMustache::initMustache to register custom functions, extensions, global variables, filters etc.

Here is an example how you can use the provided hook to attach a custom function.

wire()->addHookAfter('TemplateEngineMustache::initMustache', function (HookEvent $event) {
    /** @var \Mustache_Engine $mustache */
    $mustache = $event->arguments('mustache');

    $mustache->setHelpers([
			'myHelperFunction' => function($text) {
				return trim($text);
			}
		]);
});

// ... and then use it anywhere in a Mustache template:

{{#myHelperFunction}} {{someVariable}} {{/myHelperFunction}}

The above hook can be put in your site/init.php file. If you prefer to use modules, put it into the module's init() method and make sure that the module is auto loaded.

Install and use modules at your own risk. Always have a site and database backup before installing new modules.

“We chose ProcessWire because of its excellent architecture, modular extensibility and the internal API. The CMS offers the necessary flexibility and performance for such a complex website like superbude.de. ProcessWire offers options that are only available for larger systems, such as Drupal, and allows a much slimmer development process.” —xport communication GmbH
