Detailed Description

This class encapsulates "magic words" such as "#redirect", NOTOC, etc.

Usage:: if (MagicWord::get( 'redirect' )->match( $text ) ) {

// some code

}

Possible future improvements:

Simultaneous searching for a number of magic words
MagicWord::$mObjects in shared memory

Please avoid reading the data out of one of these objects and then writing special case code. If possible, add another match()-like function here.

To add magic words in an extension, use $magicWords in a file listed in $wgExtensionMessagesFiles[].

Example:: $magicWords = array();

$magicWords['en'] = array(

'magicwordkey' => array( 0, 'case_insensitive_magic_word' ),

'magicwordkey2' => array( 1, 'CASE_sensitive_magic_word2' ),

);

For magic words which are also Parser variables, add a MagicWordwgVariableIDs hook. Use string keys.
