Member Function Documentation

◆ buildContent()

ResourceLoaderModule::buildContent ( ResourceLoaderContext  $context)
finalprotected

Bundle all resources attached to this module into an array.

Since
1.26
Parameters
ResourceLoaderContext$context
Returns
array

Definition at line 717 of file ResourceLoaderModule.php.

References $blob, $content, $context, ResourceLoader\filter(), getHeaders(), getMessageBlob(), getName(), getScript(), getScriptURLsForDebug(), getStyles(), getStyleURLsForDebug(), getTemplates(), and ResourceLoader\makeCombinedStyles().

Referenced by getModuleContent().

◆ enableModuleContentVersion()

ResourceLoaderModule::enableModuleContentVersion ( )

Whether to generate version hash based on module content.

If a module requires database or file system access to build the module content, consider disabling this in favour of manually tracking relevant aspects in getDefinitionSummary(). See getVersionHash() for how this is used.

Returns
bool

Reimplemented in ResourceLoaderFileModule, ResourceLoaderStartUpModule, ResourceLoaderWikiModule, ResourceLoaderLanguageDataModule, and ResourceLoaderUserDefaultsModule.

◆ expandRelativePaths()

static ResourceLoaderModule::expandRelativePaths ( array  $filePaths)
static

Expand directories relative to $IP.

Since

Parameters
array$filePaths
Returns
array

◆ getConfig()

◆ getDefinitionSummary()

ResourceLoaderModule::getDefinitionSummary ( ResourceLoaderContext  $context)

Get the definition summary for this module.

This is the method subclasses are recommended to use to track data that should influence the module's version hash.

Subclasses must call the parent getDefinitionSummary() and add to the returned array. It is recommended that each subclass appends its own array, to prevent clashes or accidental overwrites of array keys from the parent class. This gives each subclass a clean scope.

$summary = parent::getDefinitionSummary( $context );
$summary[] = [
'foo' => 123,
'bar' => 'quux',
];
return $summary;

Return an array that contains all significant properties that define the module. The returned data should be deterministic and only change when the generated module response would change. Prefer content hashes over modified timestamps because timestamps may change for unrelated reasons and are not deterministic (T102578). For example, because timestamps are not stored in Git, each branch checkout would cause all files to appear as new. Timestamps also tend to not match between servers causing additional ever-lasting churning of the version hash.

Be careful not to normalise the data too much in an effort to be deterministic. For example, if a module concatenates files together (order is significant), then the definition summary could be a list of file names, and a list of file hashes. These lists should not be sorted as that would mean the cache is not invalidated when the order changes (T39812).

This data structure must exclusively contain primitive "scalar" values, as it will be serialised using json_encode.

Since
1.23
Parameters

◆ 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).

Returns
array

Definition at line 549 of file ResourceLoaderModule.php.

References $IP, and $path.

◆ getScript()

ResourceLoaderModule::getScript ( ResourceLoaderContext  $context)

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

Includes all relevant JS except loader scripts.

For "plain" script modules, this should return a string with JS code. For multi-file modules where require() is used to load one file from another file, this should return an array structured as follows: [ 'files' => [ 'file1.js' => [ 'type' => 'script', 'content' => 'JS code' ], 'file2.js' => [ 'type' => 'script', 'content' => 'JS code' ], 'data.json' => [ 'type' => 'data', 'content' => array ] ], 'main' => 'file1.js' ]

Parameters

Referenced by buildContent().

◆ 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.

Definition at line 304 of file ResourceLoaderModule.php.

References $context, $resourceLoader, getName(), and getSource().

Referenced by buildContent().

◆ 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.

Definition at line 448 of file ResourceLoaderModule.php.

◆ getSource()

ResourceLoaderModule::getSource ( )

Get the source of this module.

Should only be overridden for foreign modules.

Returns
string Source name, 'local' for local modules

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

◆ 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, and ResourceLoaderSkinModule.

Referenced by buildContent().

◆ 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()

Parameters
ResourceLoaderContext$context
Returns
array [ mediaType => [ URL1, URL2, ... ], ... ]

Since
1.28
Returns
string ResourceLoaderModule LOAD_* constant

Referenced by getFileDependencies(), ResourceLoader\preloadModuleInfo(), and setFileDependencies().

◆ getVersionHash()

ResourceLoaderModule::getVersionHash ( ResourceLoaderContext  $context)

Get a string identifying the current version of this module in a given context.

Whenever anything happens that changes the module's response (e.g. scripts, styles, and messages) this value must change. This value is used to store module responses in cache. (Both client-side and server-side.)

It is not recommended to override this directly. Use getDefinitionSummary() instead. If overridden, one must call the parent getVersionHash(), append data and re-hash.

This method should be quick because it is frequently run by ResourceLoaderStartUpModule to propagate changes to the client and effectively invalidate cache.

Since
1.26
Parameters
ResourceLoaderContext$context
Returns
string Hash (should use ResourceLoader::makeHash)

Definition at line 833 of file ResourceLoaderModule.php.

References $context, enableModuleContentVersion(), getDefinitionSummary(), getModuleContent(), and ResourceLoader\makeHash().

◆ 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 ResourceLoaderSkinModule, and ResourceLoaderWikiModule.

Definition at line 928 of file ResourceLoaderModule.php.

◆ safeFileHash()
