Hi, is there an existing way (or an extension) to generate a short well-formatted snipped around changes on a wiki page, or even just to take the top part of a page cleanly, kind of like "Today's featured article" does on wikipedia? That looks like it's edited by hand from the original article, which is understandable for its placement on the front page, but is there a way to do an automated version of that sort of thing without a human in the loop?
Basically, I'm using the WikiFeeds extension on my site for rss/atom, and it's great, but it always includes the whole page in the feed. For changes that are major enough to put in the feed, but not an entirely new page, I would like to put some snippets in the feed, but I'd like them to be well-formatted in the sense that they look like a snippet from the page in its final state, or close to this at least. It seems non-trivial given the nested hierarchical structure of wikitext/html, so I figured I'd ask if anybody has done something like it already.
Thanks, Chris
