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) of the functions from the StringFunctions extension, which may be enabled or disabled (See the install instructions below).

For instructions on how to use this extension, see the ParserFunctions help page, and the StringFunctions page.

Installation

• Download and place the file(s) in a directory called ParserFunctions in your extensions/ folder.

• Add the following code at the bottom of your LocalSettings.php:

  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.

To users running MediaWiki 1.24 or earlier:

The instructions above describe the new way of installing this extension using wfLoadExtension(). If you need to install this extension on these earlier versions (MediaWiki 1.24 and earlier), instead of wfLoadExtension( 'ParserFunctions' );, you need to use:

require_once "$IP/extensions/ParserFunctions/ParserFunctions.php";

Configuration

$wgPFEnableStringFunctions

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

$wgPFStringLengthLimit

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