Ruby Source code Auto-Formatter [closed]

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but they both seem slightly outdated.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.

well - the "best" option is justifiable to speculate on.. but I use my favorite editor, Eclipse. I have a custom formatter enabled, and i just do Ctrl+Shift+F and voila. – Decrescendo

Sublime Text 2 can "reindent" Ruby code, as can Vim. – Cromlech

I would love to see something as comprehensive as perltidy in ruby. – Creatural

rubocop is currently implementing some of this functionality. It's a style checker, but with optional auto-fixing of style-warnings. It's not nearly far enough to put it here as answer though ;) – Emmott

The first link is now dead. – Cromlech

Answer 1

There is RuboCop:

gem install rubocop
rubocop -a

It will also fix all the common mistakes.

Answer 2

Just use vim, in command mode press gg=G

1. gg - move cursor to the beginning of your file
2. = - reindent
3. G - till the end of file

Apologia

formatting is more than only indentation – Housetop
