Keep in mind that templates can have multiple extension. The order of these preprocessors is important. For example, if you called your JavaScript file app/assets/javascripts/projects.js.erb.coffee then it would be processed with the CoffeeScript interpreter first, which wouldn’t understand ERB and therefore you would run into problems. |

Thanks for this. With the latest version of flog you need to call I've add the line in the fork here: https://gist.github.com/benjaminwood/9744892 |

Anybody know how to get the ruby source from a haml file? I've spent a bit of time on this already but couldn't figure it out. It'd be cool to run this against ERB and then again after converting to HAML and refactoring. |

Run it like this:
ruby contemplative.rb /path/to/your/rails/app/
Get output like this (templates sorted by Flog score):
