I''ve been wanting to put up a RedCloth "dingus" like you find on Textism, but always thought it would take too much time and would be one more app taking up resources. Then I got a reminder email from Heroku that I wasn''t doing anything with my beta invitation. So I took them up on it. I wrote a simple Sinatra app, did a git push heroku, and basked in its glory. Nothing fancy, but it''s incredibly fast. Check it out: http://try.redcloth.org/ I plan to style it and integrate it into the reference manual (try out the examples via AJAX) at some point, but not bad for a quick hack, eh? Jason P.S.: Here''s the app: require ''rubygems'' require ''sinatra'' require ''redcloth'' get ''/'' do haml :index end post ''/'' do RedCloth.new(params[:text]).to_html end
