Ruby coding style guidelines

Question

Is there a document for Ruby that describes some preferred conventions for whitespace, indentation and other style issues?

I found Python's PEP 8 to be very helpful and am looking for something similar for Ruby.

Answer 1

There's nothing official, but the two common guidelines are:

• RubyCodingConventions (Click the preview button)
• The Unofficial Ruby Usage Guide

Of the two, I find the second one more informative.

Answer 2

http://github.com/chneukirchen/styleguide/ is awesome.

Answer 3

I wrote some thoughts a while back at http://www.pathf.com/blogs/ruby-and-rails-style-guide/
