Answer 1

This should be a task of your editor. In vim (configured for Ruby), just press gg=G xD

A Ruby script that does it is available at: http://www.arachnoid.com/ruby/rbeautify.rb.html

That was exactly the script I was looking for (thnx). Tried it, commit 15c34bf shows an example. – Supposal

btw I suspect TextMate ships with built-in Ruby support, so that a plus. VIM will do it, but that needs adjustment. I wanted something that's available from the command line to prevent the editor minefield (for TextMate, you need a licence, for VIM you need plugins, etc.). – Supposal
