It’s nice to do some Ruby once in a while. Lately I’ve been involved in a Silverlight project and haven’t touched Ruby in 2 months (hence the lack of activity on my Ruby blog). However, I’m making a build script in Ruby.

I have run into a weird exception when using my favorite IO gem RIO (btw, Noobkit page got beaten with the ugly stick and parser needs a spanking).

Exception occur when calling rio(...).rmtree or rio(...).mkpath or rio(...).mkdir. It reads as follows: “wrong number of arguments (0 for 1)”. I know for a fact that these methods don’t take any arguments, but just for kicks, passing a single random argument results in an ironic “wrong number of arguments (1 for 0)”.

Basically the problem came down to the fact that RIO doesn’t like Rake. I can live without Rake, but not without RIO.
