Ruby Koans

Dax Huiberts ma 23 aug 10

Ruby Koans is a new interesting project to help you learn Ruby using a test driven approach.

The Koans walk you along the path to enlightenment in order to learn Ruby. The goal is to learn the Ruby language, syntax, structure, and some common functions and libraries. We also teach you culture. Testing is not just something we pay lip service to, but something we live. It is essential in your quest to learn and do great things in the language.

Some more info about the structure of Ruby Koans:

The koans are broken out into areas by file, hashes are covered in about_hashes.rb, modules are introduced in about_modules.rb, etc. They are presented in order in the path_to_enlightenment.rb file.

Each koan builds up your knowledge of Ruby and builds upon itself. It will stop at the first place you need to correct.

Some koans simply need to have the correct answer substituted for an incorrect one. Some, however, require you to supply your own answer. If you see the method __ (a double underscore) listed, it is a hint to you to supply your own code in order to make it work correctly.

I’ve taken it for a short run and it’s very enlightening and entertaining. There’s no doubt you will learn some Ruby features or tricks you don’t know about yet.
