Detailed Description

Dynamic JavaScript and CSS resource loading system.

Most of the documentation is on the MediaWiki documentation wiki starting at: https://www.mediawiki.org/wiki/ResourceLoader

Definition at line 37 of file ResourceLoader.php.

Constructor & Destructor Documentation

ResourceLoader::__construct ( Config  $config = null,
LoggerInterface  $logger = null 
)

Register core modules and runs registration hooks.

Parameters
Config$config[optional]
LoggerInterface$logger[optional]

Definition at line 236 of file ResourceLoader.php.

References $config, $IP, addSource(), global, registerTestModules(), Hooks\run(), setMessageBlobStore(), and true.

Member Function Documentation

ResourceLoader::addSource (   $id,
  $loadUrl = null 
)

Add a foreign source of modules.

Source IDs are typically the same as the Wiki ID or database name (e.g. lowercase a-z).

Parameters
array | string$idSource ID (string), or [ id1 => loadUrl, id2 => loadUrl, ... ]
string | array$loadUrlload.php url (string), or array with loadUrl key for backwards-compatibility.
Exceptions
MWException

static ResourceLoader::applyFilter (   $filter,
  $data 
)
staticprivate
static ResourceLoader::clearCache ( )
static

Reset static members used for caching.

Global state and $wgRequest are evil, but we're using it right now and sometimes we need to be able to force ResourceLoader to re-evaluate the context because it has changed (e.g. in the test suite).

ResourceLoader::makeVersionQuery ( ResourceLoaderContext  $context)

ResourceLoader::outputErrorAndLog ( Exception  $e,

ResourceLoader::preloadModuleInfo ( array  $moduleNames,
ResourceLoaderContext  $context 
)

Load information stored in the database about modules.

This method grabs modules dependencies from the database and updates modules objects.

This is not inside the module code because it is much faster to request all of the information at once than it is to have each module requests its own information. This sacrifice of modularity yields a substantial performance improvement.

Parameters
array$moduleNamesList of module names to preload information for
ResourceLoaderContext$contextContext to load the information within

ResourceLoader::register (   $name,
  $info = null 
)

Register a module with the ResourceLoader system.

Parameters
mixed$nameName of module as a string or List of name/object pairs as an array
array$infoModule info array. For backwards compatibility with 1.17alpha, this may also be a ResourceLoaderModule object. Optional when using multiple-registration calling style.
Exceptions
MWExceptionIf a duplicate module registration is attempted
MWExceptionIf a module name contains illegal characters (pipes or commas)
MWExceptionIf something other than a ResourceLoaderModule is being registered
Returns
bool False if there were any errors, in which case one or more modules were not registered
