wiki in rails?

can anyone recommend a simple, maintained wiki project?

i've never found anything in rails to compete with moinmoin. instiki
seems to be slightly maintained again (at least some activity in 2010)
but have had problems with that before.


There is magmawiki in development, you should find it via github. As far as I know it ported to Rails 3 in the moment. But I can’t say how actively it is developed at the moment, since I left the team 6 months ago, 2 month after starting of the project. I wanted to help with German localization, but my job came into my way.

It was planned to make the markup Mediawiki compatible and add further support for BB and other formatting style.
