Reek Rake Task
This will use the <a href="http://github.com/kevinrutherford/reek/tree/master">Reek Ruby Gem</a> and Rake to go through your Rails app and call Reek on every .rb file. It pipes the Reek output to a file in public/reek/file_name.rb.txt and generates an index.html file in public/reek/ with links to view each text file. I wrote this Rake task because I couldn't seem to run Reek on my Rails app's app/ directory; maybe I just didn't read enough about Reek's usage.
Save this file with the extension .rake in your Rails app's lib/tasks/ directory, e.g. lib/tasks/reek.rake. You can then run 'rake reek' on the command line within your Rails app's directory. You will need Reek to be installed first, and Reek should be runnable just by typing 'reek'.
