视觉差异(visual diff)比较和显示渲染(或显示)文档之间的差异,而不是出格式化的文档文本(或标记)。

The main approach for visual diffs in MediaWiki is the visual diffs system (pictured) provided by the VisualEditor extension, which compares the HTML of two documents. It provides visual diffs in VisualEditor's editing preview, as well as (still as a beta feature) in MediaWiki's standard diff display.

Another option for visual diffs is the VisualDiff extension, which adds visual diffs directly to the history page.

Previous attempts at visual diffs in MediaWiki include:

  • As part of their testing efforts, the Parsing team created the "Visual Diff Testing" tool (released around April 2016), which is a pixel differ of the page rendered as an image, used to identify differences between Parsoid and the legacy parser.
