After I launched the Ruby Style Guide I often received requests to create a tool enforcing the rules in the guide automatically.
Today this tool is a reality – meet RuboCop. RuboCop already covers a significant portion of the Guide, supports both MRI 1.9 and MRI 2.0 and has pretty neat Emacs integration(via rubocop.el and flycheck).
I’d love to see more Ruby hackers check out RuboCop!
I’d love to thank all the great people who contributed code, issue reports and ideas to RuboCop’s development and I sincerely hope many Ruby hackers will find it useful!
