The ParserMigration extension was introduced in gerrit:296182. It provides an interface for comparing article rendering with a new non-default version of the MediaWiki parser thus serving as a parser migration tool.

It was deployed on the Wikimedia production cluster until 2018 to compare Tidy-based output with a RemexHTML-based output. RemexHTML is the replacement for Tidy.

The availability of the tool can be controlled by a user via the "parsermigration" preference option.

Installation

• Download and place the file(s) in a directory called ParserMigration in your extensions/ folder.
• Add the following code at the bottom of your LocalSettings.php:
