It's in Perl, unfortunately. Anyone want to help add search and change
history to RuWiki?
Change history is on its way -- I can't give a target, because I just
started refactoring the new diff code to be a bit more Ruby-ish rather
than Perl-ish, and it's somewhat taken on a life of its own. I'm out of
town this weekend, so perhaps a release of that (a standalone project,
too!) will happen early next week. Ruwiki can follow after that, because
the page format is changing (dramatically) for Ruwiki 0.8; after that, if
people want to help, the page format will be stable and extensible. (One
of the features that I thought would be neat are "image-pages"; that is,
Ruwiki topic pages that are essentially just JPG, GIF, or PNG images. This
will be possible, at least in theory, with the new page format.)
