The ParserFunctions extension enhances the wikitext parser with helpful functions, mostly related to logic and string handling. Since MediaWiki 1.15, ParserFunctions has incorporated most (but not all) functions from the former StringFunctions extension, which may be enabled or disabled.

For instructions on how to use this extension, see the help pages.

Installation

• Download and move the extracted ParserFunctions folder to your extensions/ directory.
  Developers and code contributors should install the extension from Git instead, using:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/ParserFunctions
• Add the following code at the bottom of your LocalSettings.php file:

  wfLoadExtension( 'ParserFunctions' );
  

• Configure as required, e.g., if you want to use the integrated string function functionality, add just after that line:

$wgPFEnableStringFunctions = true;

•  Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Configuration

$wgPFEnableStringFunctions

Allows to activate the integrated string function functionality (see string functions ). The default value is false.

$wgPFStringLengthLimit

Defines the maximum length of a string that string functions can operate on. The default value is 1000.
