My colleague just released textilize, a drop-in replacement for the old textilize helpers in Rails 2.x. If you are updating an older app to Rails 3.x, it may be of use. Textilize is different from other textile gems that exist because includes the pure ruby version of RedCloth written by _why. Other gems require the new 4.x version of RedCloth that needs to be compiled. We just have a few small uses for textilize, and needed something that worked without any extra dependencies. Hope you can find it useful too.
