Allows to output the text of the article revision in a different format than wikitext. Note that it is preferable to implement proper handing for a custom data type using the ContentHandler facility.

  • $revision: revision of the page, as a MediaWiki\Revision\RevisionRecord object (or null if the revision could not be loaded). This may also be a fake revision that wraps content supplied by an extension.
  • $title: the page, as a Title object
  • $oldId: the requested revision ID, or 0 for the current revision
  • $output: An instance of OutputPage

This hook replaces the ArticleAfterFetchContentObject hook.
