Details
Configure the ParserFactory service in order to customize the Parser used.

Associative array with the following members:


 * class
 * The class name


 * preprocessorClass
 * The preprocessor class. Two classes are currently available: Preprocessor_Hash, which uses plain PHP arrays for temporary storage, and Preprocessor_DOM, which uses the DOM module for temporary storage. Preprocessor_DOM generally uses less memory; the speed of the two is roughly the same.
 * If this parameter is not given, it uses Preprocessor_DOM if the DOM module is available, otherwise it uses Preprocessor_Hash.

The entire associative array will be passed through to the constructor as the first parameter. Note that only Setup.php can use this variable -- the configuration will change at runtime via $wgParser member functions, so the contents of this variable will be out-of-date. The variable can only be changed during LocalSettings.php, in particular, it can't be changed during an extension setup function.
