magicword.txt Magic Words are some phrases used in the wikitext. They are used for two things: * Variables (like {{PAGENAME}}, {{SERVER}}, ...): part of wikitext, that looks like templates but that don't accept any parameter. * Parser functions (like {{fullurl:...}}, {{#special:...}}): behaves like functions and accepts parameters. The localized arrays keys are the internal name, and the values are an array, whose include their case-sensitivity and their alias forms. The first form defined is used by the program, for example, when moving a page and its old name should include #REDIRECT. They can be added in several arrays: * By adding a file to $wgExtensionMessagesFiles and defining there $magicWords. This array is associative with the language code in the first dimension key and then a "normal" array of magic words. * Localized arrays (languages/messages/LanguageXX.php) include their different names to be used by the users. To add a new variable, you should use the "MagicWordwgVariableIDs" hook to add the internal name to the $magicWords array. You'll need to define the value of the variable with the "ParserGetVariableValueSwitch" hook. For example to add a new variable: Create a file called ExtensionName.i18n.magic.php with the following contents: ---- array( 1, 'CUSTOM' ), ); $magicWords['es'] = array( 'mag_custom' => array( 1, 'ADUANERO' ), ); ---- $wgExtensionMessagesFiles['ExtensionNameMagic'] = __DIR__ . '/ExtensionName.i18n.magic.php'; $wgHooks['MagicWordwgVariableIDs'][] = 'wfAddCustomMagicWordID'; $wgHooks['ParserGetVariableValueSwitch'][] = 'wfGetCustomMagicWordValue'; function wfAddCustomMagicWordID( &$magicWords ) { $magicWords[] = 'mag_custom'; return true; } function wfGetCustomMagicWordValue( &$parser, &$varCache, &$index, &$ret ){ if( $index == 'mag_custom' ){ $ret = $varCache['mag_custom'] = "Custom value"; } return true; } And to add a new parser function: Create a file called ExtensionName.i18n.magic.php with the following contents: ---- array( 0, 'custom' ), ); $magicWords['es'] = array( 'mag_custom' => array( 0, 'aduanero' ), ); ---- $wgExtensionMessagesFiles['ExtensionNameMagic'] = __DIR__ . '/ExtensionName.i18n.magic.php'; $wgHooks['ParserFirstCallInit'][] = 'wfRegisterCustomMagicWord'; function wfRegisterCustomMagicWord( &$parser ){ $parser->setFunctionHook( 'mag_custom', 'wfGetCustomMagicWordValue' ); return true; } function wfGetCustomMagicWordValue( &$parser, $var1, $var2 ){ return "custom: var1 is $var1, var2 is $var2"; } Note: the 'ParserFirstCallInit' hook is only available since 1.12. To work with an older version, you'll need to use an extension function.
