Parser: $wgParserConf
Parser configuration.
Introduced in version:	1.12.0
Removed in version:	still in use
Allowed values:	(array)
Default value:	[ 'class' => Parser::class, # 'preprocessorClass' => Preprocessor_Hash::class, ]
Other settings: Alphabetical | By function

Details

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-- the configuration will change at runtime via $wgParser member functions, so the contents of this variable will be out-of-date.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