MadRuby is an on-the-fly keyboard macro recorder. You simply start recording while using any application, perform a task using the keyboard, stop recording and play it back as many times as you want, anywhere you want.
Use MadRuby to take care of those one off repetitive tasks that aren't worth creating a snippet for in Willow.
Note: Please note that MadRuby is not currently maintained, I aim to do a full update (it will still be free), modernize it and support OS X 10.10 Yosemite but unfortunately my paid work is taking up all my time. If you find it useful still feel free to contact me for support and request features, I'll do my best to fix bugs immediately but features will come with the full update.
