comments on the code

Newer versions of MoinMoin should use a different regex for finding the dates within blog entries. -- SteveHowell

The code above didn't work on MoinMoin Release 1.0 [Revision 1.159]. To fix the problem I changed the return of execute() to: return Parser(result, macro.request).format(macro.formatter, fakeCgiForm)

I'm a nubie to wiki, but wouldn't it be more efficient to loop through the pages in reverse chrono order by mod date, and then drop out of the loop when count had been reached? that way we don't have to search pages that won't be included. --Jeremy Elliott (no wiki page yet)

The page's modification date doesn't necessarily relate to the latest blog entry on the page. You can edit a page that has been blogged. -- SteveHowell
