Detailed Description

Abstraction for ResourceLoader modules which pull from wiki pages.

This can only be used for wiki pages in the MediaWiki and User namespaces, because of its dependence on the functionality of Title::isUserConfigPage() and Title::isSiteConfigPage().

This module supports being used as a placeholder for a module on a remote wiki. To do so, getDB() must be overloaded to return a foreign database object that allows local wikis to query page metadata.

Safe for calls on local wikis are:

Option getters:
- getGroup()
- getPages()
Basic methods that strictly involve the foreign database
- getDB()
- isKnownEmpty()
- getTitleInfo()

Since: 1.17

Constructor & Destructor Documentation

◆ __construct()

ResourceLoaderWikiModule::__construct ( array $options = null )

Parameters

array | null $options For back-compat, this can be omitted in favour of overwriting getPages.

Reimplemented in GadgetResourceLoaderModule.

Definition at line 86 of file ResourceLoaderWikiModule.php.

Member Function Documentation

◆ enableModuleContentVersion()

ResourceLoaderWikiModule::enableModuleContentVersion ( )

Disable module content versioning.

This class does not support generating content outside of a module request due to foreign database support.

See getDefinitionSummary() for meta-data versioning.

Returns: bool

Reimplemented from ResourceLoaderModule.

Definition at line 321 of file ResourceLoaderWikiModule.php.

◆ fetchTitleInfo()

static ResourceLoaderWikiModule::fetchTitleInfo	(	IDatabase	$db,
		array	$pages,
			$fname = __METHOD__ )

staticprotected

Returns: array

◆ getContent()

ResourceLoaderWikiModule::getContent	(		$titleText,
		ResourceLoaderContext	$context )

protected

Parameters

string	$titleText
ResourceLoaderContext	$context

Returns: null|string

Since: 1.32 added the $context parameter

◆ getContentObj()

ResourceLoaderWikiModule::getContentObj	(	Title	$title,
		ResourceLoaderContext	$context,
			$maxRedirects = null )

protected

Parameters

Title	$title
ResourceLoaderContext	$context
int \| null	$maxRedirects	Maximum number of redirects to follow. If null, uses $wgMaxRedirects

Returns: Content|null

Since: 1.32 added the $context and $maxRedirects parameters

Referenced by getContent(), and getContentObj().

◆ getDB()

ResourceLoaderWikiModule::getDB ( )

protected

Get the Database handle used for computing the module version.

Subclasses may override this to return a foreign database, which would allow them to register a module on wiki A that fetches wiki pages from wiki B.

The way this works is that the local module is a placeholder that can only computer a module version hash. The 'source' of the module must be set to the foreign wiki directly. Methods getScript() and getContent() will not use this handle and are not valid on the local wiki.

Returns: IDatabase

Definition at line 162 of file ResourceLoaderWikiModule.php.

References DB_REPLICA, and wfGetDB().

◆ getDefinitionSummary()

ResourceLoaderWikiModule::getDefinitionSummary ( ResourceLoaderContext $context )

Parameters

ResourceLoaderContext $context

Returns: array

Reimplemented from ResourceLoaderModule.

Definition at line 329 of file ResourceLoaderWikiModule.php.

References $context, getPages(), and getTitleInfo().

◆ getGroup()

ResourceLoaderWikiModule::getGroup ( )

Get group name.

Returns: string

Reimplemented from ResourceLoaderModule.

Reimplemented in GadgetResourceLoaderModule, ResourceLoaderSiteStylesModule, ResourceLoaderUserModule, and ResourceLoaderUserStylesModule.

Definition at line 144 of file ResourceLoaderWikiModule.php.

Referenced by isKnownEmpty().

◆ getPages()

ResourceLoaderWikiModule::getPages ( ResourceLoaderContext $context )

protected

Subclasses should return an associative array of resources in the module.

Keys should be the title of a page in the MediaWiki or User namespace.

Values should be a nested array of options. The supported keys are 'type' and (CSS only) 'media'.

For scripts, 'type' should be 'script'.

For stylesheets, 'type' should be 'style'. There is an optional media key, the value of which can be the medium ('screen', 'print', etc.) of the stylesheet.

Parameters

ResourceLoaderContext $context
