Ruby metaprogramming online tutorial

Question

I have just started to learn Ruby and got a good take on the basics. I keep hearing that one of the cool things that Ruby does very well is metaprogramming, but none of the tutorials I've read cover this. Searching Google I can only seem to find paid for ruby metaprogramming screen casts.

So, where can I find a good Ruby metaprogramming tutorial online?

Answer 4

If you are prepared to outlay a little cash, then The Pragmatic Programmers website has an excellent screencast series on the Ruby Object Model and metaprogramming. It's not very expensive and is a very comprehensive series that goes over a lot of cool stuff and worth every cent.

I need to watch it again to try and get my head around some of the concepts, then I can be one of the cool meta crowd :)

Answer 5

It's easy to do meta programming in Ruby. Here is a 16-posts series on meta programming in Ruby.
