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 is currently deployed on the Wikimedia production cluster to compare Tidy-based output with a RemexHTML-based output. RemexHTML is a proposed replacement for Tidy.

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

Installation[edit source]
