Parser: $wgParserConf
Parser configuration.
Introduced in version:1.12.0
Deprecated in version:1.35.0
Removed in version:still in use
Allowed values:(array)
Default value:(see below)


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

Associative array with the following members:

The class name
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-- the configuration will change at runtime via $wgParser member functions, so the contents of this variable will be out-of-date.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.
