There seem to be a number of simple text-formatting modules available
for Ruby, including RedCloth, BlueCloth, SuperRedCloth, and Maruku. It
seems that the latest release of RedCloth is simply unusable
(:filter_html doesn’t work at all), and the project has been abandoned
in favour of SuperRedCloth, which is still heavily under development.
Does anyone have any opinions of any other Markdown/Textile modules,
which are stable and provide useful fucntions like filter rules?
