Ruby Source code Auto-Formatter

Question

What is the best option? I found:

• https://github.com/jasonl/eden
• http://www.arachnoid.com/ruby/rubyBeautifier.html

but they both seem slightly outdated. Special support for Rails (Knowing which files to format automagically and some other cool things) would be a plus, and a git hook script.

Answer 1

There is RuboCop:

gem install rubocop
rubocop -a

It will also fix all the common mistakes.
