Description

Author: Wiki.Melancholie

Description:
News feed readers and Mozilla Thunderbird e.g. do show a colored revision comparison for Atom/RSS feeds.

But sometimes changed words/content is not shown red¹, see

  1. https://de.wikibooks.org/w/index.php?title=Esperanto&diff=374797&oldid=364671 (where it was¹ red)
  2. https://de.wikibooks.org/w/index.php?title=Esperanto&feed=rss&action=history (where no red color was used¹)
  3. https://de.wikibooks.org/w/index.php?title=Linux-Kompendium&feed=rss&action=history (where style code was marking words red¹)

So, sometimes style="color: red; font-weight: bold; text-decoration: none;" was¹ missing; instead class="diffchange diffchange-inline" is used, but does not work (at least for Thunderbird). This occurs for RSS and Atom.

Notes
¹ T13374 changed the diff color scheme from red/green/yellow to orange/blue/bold.

Version: unspecified

The styles are applied by hardcoding to the feed output by rcApplyDiffStyle() in SpecialRecentchanges.php.

This function is a bit of a hack, and doesn't properly handle multiple classes (eg class="diffchange diffchange-inline"), which are now produced due to recent changes to the diff engine. (But not _always_ produced on Wikipedia, since we currently have a mix of wikidiff2 versions installed.)

The function should be updated to handle multiple classes, either with another hack or by rewriting it to use proper DOM functions or such.

That is T36801: Function applyDiffStyle uses regexes which do not detect CSS classes appropriately.
