Return an array containing values from all significant properties of this module's definition.

Be careful not to normalise too much. Especially preserve the order of things that carry significance in getScript and getStyles (T39812).

Avoid including things that are insiginificant (e.g. order of message keys is insignificant and should be sorted to avoid unnecessary cache invalidation).

This data structure must exclusively contain arrays and scalars as values (avoid object instances) to allow simple serialisation using json_encode.

If modules have a hash or timestamp from another source, that may be incuded as-is.

A number of utility methods are available to help you gather data. These are not called by default and must be included by the subclass' getDefinitionSummary().

◆ getHashMtime()

ResourceLoaderModule::getHashMtime ( ResourceLoaderContext $context )

Back-compat dummy for old subclass implementations of getModifiedTime().

This method used to use ObjectCache to track when a hash was first seen. That principle stems from a time that ResourceLoader could only identify module versions by timestamp. That is no longer the case. Use getDefinitionSummary() directly.

Deprecated:: since 1.26 Superseded by getVersionHash()

Parameters

ResourceLoaderContext $context

Returns: int UNIX timestamp

Definition at line 964 of file ResourceLoaderModule.php.

References getModifiedHash().

◆ getHeaders()

ResourceLoaderModule::getHeaders ( ResourceLoaderContext $context )

final

Get headers to send as part of a module web response.

It is not supported to send headers through this method that are required to be unique or otherwise sent once in an HTTP response because clients may make batch requests for multiple modules (as is the default behaviour for ResourceLoader clients).

For exclusive or aggregated headers, see ResourceLoader::sendResponseHeaders().

Since: 1.30

Parameters

Deprecated:: since 1.26 Use getDefinitionSummary() instead

Parameters

ResourceLoaderContext $context Context object

Returns: int|null UNIX timestamp

Definition at line 938 of file ResourceLoaderModule.php.

Definition at line 126 of file ResourceLoaderModule.php.

References $origin.

Referenced by OutputPage\filterModules().

◆ getPosition()

ResourceLoaderModule::getPosition ( )

Deprecated:: since 1.29 Obsolete. All modules load async from <head>.

Returns: string

Reimplemented in ResourceLoaderTestModule.

Definition at line 339 of file ResourceLoaderModule.php.

◆ getRelativePaths()

static ResourceLoaderModule::getRelativePaths ( array $filePaths )

static

Make file paths relative to MediaWiki directory.

This is used to make file paths safe for storing in a database without the paths becoming stale or incorrect when MediaWiki is moved or upgraded (T111481).

Since: 1.27

Parameters

array $filePaths

Returns: array

Definition at line 531 of file ResourceLoaderModule.php.

References $IP, $path, global, and use.

Referenced by saveFileDependencies().

◆ getScript()

ResourceLoaderModule::getScript ( ResourceLoaderContext $context )

Get all JS for this module for a given language and skin.

Includes all relevant JS except loader scripts.

Parameters

ResourceLoaderContext $context

Returns: string JavaScript code

Definition at line 169 of file ResourceLoaderModule.php.

◆ getScriptURLsForDebug()

ResourceLoaderModule::getScriptURLsForDebug ( ResourceLoaderContext $context )

Get the URL or URLs to load for this module's JS in debug mode.

The default behavior is to return a load.php?only=scripts URL for the module, but file-based modules will want to override this to load the files directly.

This function is called only when 1) we're in debug mode, 2) there is no only= parameter and 3) supportsURLLoading() returns true. #2 is important to prevent an infinite loop, therefore this function MUST return either an only= URL or a non-load.php URL.

Parameters

ResourceLoaderContext $context

Returns: array Array of URLs

Reimplemented in ResourceLoaderFileModule, ResourceLoaderJqueryMsgModule, and ResourceLoaderSyntaxHighlightVisualEditorModule.

Definition at line 239 of file ResourceLoaderModule.php.

Referenced by ResourceLoaderSyntaxHighlightVisualEditorModule\getScriptURLsForDebug(), and ResourceLoaderJqueryMsgModule\getScriptURLsForDebug().

◆ getSkipFunction()

ResourceLoaderModule::getSkipFunction ( )

Get the skip function.

Modules that provide fallback functionality can provide a "skip function". This function, if provided, will be passed along to the module registry on the client. When this module is loaded (either directly or as a dependency of another module), then this function is executed first. If the function returns true, the module will instantly be considered "ready" without requesting the associated module resources.

The value returned here must be valid javascript for execution in a private function. It must not contain the "function () {" and "}" wrapper though.

Returns: string|null A JavaScript function body returning a boolean value, or null

Reimplemented in ResourceLoaderFileModule, and ResourceLoaderTestModule.

Definition at line 404 of file ResourceLoaderModule.php.

◆ getSource()

ResourceLoaderModule::getSource ( )

Get the origin of this module.

Should only be overridden for foreign modules.

Returns: string Origin name, 'local' for local modules

Reimplemented in ResourceLoaderTestModule.

Definition at line 328 of file ResourceLoaderModule.php.

Referenced by getScriptURLsForDebug(), ResourceLoaderImageModule\getStyles(), and getStyleURLsForDebug().

◆ getStyles()

ResourceLoaderModule::getStyles ( ResourceLoaderContext $context )

Get all CSS for this module for a given skin.

Parameters

ResourceLoaderContext $context

Returns: array List of CSS strings or array of CSS strings keyed by media type. like [ 'screen' => '.foo { width: 0 }' ]; or [ 'screen' => [ '.foo { width: 0 }' ] ];

Reimplemented in ResourceLoaderFileModule, ResourceLoaderImageModule, ResourceLoaderWikiModule, ResourceLoaderTestModule, and ResourceLoaderSkinModule.

Definition at line 272 of file ResourceLoaderModule.php.

◆ getStyleURLsForDebug()

ResourceLoaderModule::getStyleURLsForDebug ( ResourceLoaderContext $context )

Get the URL or URLs to load for this module's CSS in debug mode.

The default behavior is to return a load.php?only=styles URL for the module, but file-based modules will want to override this to load the files directly. See also getScriptURLsForDebug()

ResourceLoaderContext $context

Returns: array [ mediaType => [ URL1, URL2, ... ], ... ]

Reimplemented in ResourceLoaderFileModule.

Definition at line 286 of file ResourceLoaderModule.php.

Returns: array of templates mapping template alias to content

Reimplemented in ResourceLoaderFileModule.

Definition at line 179 of file ResourceLoaderModule.php.

◆ getType()

ResourceLoaderModule::getType ( )

Get the module's load type.

Since: 1.28

Returns: string ResourceLoaderModule LOAD_* constant

Definition at line 386 of file ResourceLoaderModule.php.

References LOAD_GENERAL.

◆ isKnownEmpty()

ResourceLoaderModule::isKnownEmpty ( ResourceLoaderContext $context )

Check whether this module is known to be empty.

If a child class has an easy and cheap way to determine that this module is definitely going to be empty, it should override this method to return true in that case. Callers may optimize the request for this module away if this function returns true.

Parameters

ResourceLoaderContext $context

Returns: bool

Reimplemented in ResourceLoaderWikiModule, ResourceLoaderTestModule, and ResourceLoaderSkinModule.

Definition at line 997 of file ResourceLoaderModule.php.

◆ isRaw()

ResourceLoaderModule::isRaw ( )
