VisualDiff enables users to easily compare two versions of a wiki page.

Usage / features[edit | edit source]

There are three diff views:

1. Visual: The differences are shown in the flow text. Changes are highlighted in color.

2. WikiText: The output is shown in WikiCode in an integrated view. Changes are highlighted in color.

3. Classic: The output is in WikiCode. Old and new text face each other in two columns.

  • You can switch between the views via tabs.
  • The Java command-line tool DaisyDiff creates a unified diff from two revisions rendered in HTML. This is displayed on a SpecialPage.
  • Additional information is displayed, e.g., the compared revisions.
  • A navigation to the previous difference is displayed. The behavior is similar to that of MediaWiki.
  • You can jump from one change to the next via flyout.

Technical information[edit | edit source]

The extension VisualDiff is based on the HTML-Diff tool DaisyDiff and shall give a quick and visually appealing overview of the changes in revisions of a wiki article. The changes are displayed in a so called Unified-Diff and therefore in a document and not like usual in two columns. The normal link to the diff view of MediaWiki is overwritten by a link to a special page. The article revision (oldid) works as a basis for the comparison. This also defines the changes like "added" and "deleted".
