MediaWiki 1.25 以降、MediaWiki はサーバー上およびクライアント上の Mustache テンプレートから HTML コンテンツを生成できます。 Server-side template parsing is implemented in PHP via the TemplateParser class, which acts as a wrapper around the lightncandy library. Client-side templates are supported via mediawiki.template* ResourceLoader modules and the mustache.js library.

This is unrelated to the use of MediaWiki templates in wikitext (such as the {{MW file }} in this article). Templating here builds the HTML of a web page, not the wiki content within it.

テンプレートの作成

To use HTML templates in your code, first create a Mustache template file with a .mustache file extension, for example, MyWidget.mustache. Templates should contain as little programming logic as possible so that they are easily readable and provide proper separation of concerns. If your template is part of the core MediaWiki software, put it in core's includes/templates directory. If it is part of an extension, you should create a dedicated templates directory within your extension's directory to hold it. Templates should follow the Mustache-5 specification.

TemplateParser (server-side)

MediaWiki ファイル: TemplateParser.php
場所: includes/Html/
ソース コード: master • 1.42.3 • 1.41.4 • 1.39.10
クラス: TemplateParser

Before MW 1.40.1:

MediaWiki ファイル: TemplateParser.php
場所: includes/
ソース コード: master • 1.42.3 • 1.41.4 • 1.39.10
クラス: TemplateParser

This class finds template files, reads them, compiles them into PHP code, and expands tags in the template using data you provide to produce the output HTML. MediaWiki compiles templates as needed, and uses caching to store the compiled templates if available (see #Caching below). This avoids developers having to compile templates into PHP files during development or as a build step, or the server writing them to the file system during operation.

To use TemplateParser, first create a new instance of the class: 

$templateParser = new TemplateParser();

If your Mustache templates do not reside in core's includes/templates, you need to pass the path to where they reside as the first parameter to the constructor (either relative to your MediaWiki root or relative to the calling file's directory with __DIR__): 

$templateParser = new TemplateParser(  __DIR__ . '/templates' );

You then parse templates into HTML by invoking the processTemplate() function. The first parameter to this is the name of your template (the part of the filename before .mustache). The second parameter is an array providing the values needed by the Mustache tags in your template. For example, 

echo $templateParser->processTemplate(
    'MyWidget',
    [
        'username' => $user->getName(),
        'message' => 'Hello!'
    ]
);

This replaces any instances of {{username}} and {{message}} tags in the "MyWidget" mustache template with the values you provided, and returns the resulting HTML. (The echo simply prints the generated HTML in the current output context.)

As an example of HTML templating, see includes/templates/NoLocalSettings.mustache as used by includes/Output/NoLocalSettings.php.

Caching

TemplateParser attempts to cache the compiled PHP template. It prefers to use CACHE_ACCEL (See Manual:APC ), but falls back to CACHE_ANYTHING (a general object cache like Memcached or Redis, see Manual:Caching ).

CACHE_ACCEL requires the "apc" extension in PHP 5.4 or earlier, and the "apcu" extension for PHP 5.5+. HHVM has it built-in.

Partials

The cache is keyed on a hash of the template file's contents, so if you change a template file, the compiled template will update (you may need to clear your wiki's front-end cache using ?action=purge). However, this does not notice changes to "partial" templates that you include with {{>SubTemplateName}} (bug T113095). So if you change a partial, you need to make cosmetic changes to the parent templates that include it, or restart your cache.


mw.template (client-side)

To use a Mustache template on the client-side, add it to your ResourceLoader module definition first: 

'ext.coolExtension.interface' => [
	'templates' => [
		'foo.mustache' => 'templates/foo.mustache',
	],
	'scripts' => [
		'resources/interface.js',
	],
],

The template definition above consists of two pieces, a file path (templates/foo.mustache) and an optional alias (foo.mustache). The alias must be suffixed with the name of the templating language (e.g. '.mustache') so that it knows which compiler to use. ResourceLoader automatically serves the supporting mediawiki.template.xx JavaScript modules, so you don't need to mention anything in dependencies. Once you have added the template to your module, you can retrieve it in JavaScript using mw.template.get(): 

myTemplate = mw.template.get( 'ext.coolExtension.interface', 'foo.mustache' );

To render the template and data into HTML output, call the compiled template's render() function: 

data = {
	username: mw.config.get( 'wgUserName' ),
	message: 'Hello!'
};
$html = myTemplate.render( data );

Partials are also supported on the client-side. See https://mustache.github.io/mustache.5.html#Partials for more information.
