Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
I think we need some more testing examples.
You just missed to comment the return line with "I know kung fu" (: nice use of regex!
Dudes, I'm new to Ruby as much of you (: I'm just a Clipper programmer - who also know a little bit of Fortran/Cobol/Ruby/Python/PHP/Javascript/put/here/some/another/language.. And I believe that readability runs side-by-side with syntax, patterns, code-styling and shit C: and that's the joy of develop: everyone has one particular way to solve questions, depending the project you're on you need to follow some practices.. And that's all. Adaptation is the key. So if you follow some universal patterns or conventions you'll be never wrong.
Strength and honor!
