This feature was removed completely in version 1.33.0 (after being deprecated in 1.16.0).

public static function onLanguageGetMagic( array &$magicWords, $langCode ) { ... }

{
	"Hooks": {
		"LanguageGetMagic": "MyExtensionHooks::onLanguageGetMagic"
	}
}

See Magic Words for current implementations.

LanguageGetMagic was an event for which a hook was available. Correspondingly it is an index of the array $wgHooks . The array value is an array of function names. To add a function name, a parser function extension can use a statement like:

     $wgHooks['LanguageGetMagic'][]       = "function_defining_magic_words";

These functions provide for each parser function, optionally depending on $Langcode, a list of names that can be used in the wikitext for the parser function, and whether these names are case-sensitive (0=no, 1=yes):

 	$magicWords['magic_word_ID']    = array( case_sensitivity_code, comma-separated_list_of_magic_words );

Thus in the simplest case it defines a single name for a single function, independent of language:

 function ''function_defining_magic_words''( &$magicWords, $langCode ) {
     $magicWords['magic_word_id'] = array( 0, 'function_name_in_wikitext' );
     return true; // unless we return true, other parser function extensions won't get loaded.
 }

Function setFunctionHook in Parser.php fills array mFunctionSynonyms with magic word IDs for all synonyms in the applicable language of all functions:

		$this->mFunctionSynonyms[$sensitive][$syn] = $id;

and uses this in function braceSubstitution to convert a function synonym to a function ID.

In MediaWiki 1.6.x

Prior to MW 1.7, there was only one argument, which contained the array of magic words for the current language.
