Writing a simple ruby debugger

Question

I'm thinking of writing a basic ruby debugger (interactive), Can you direct me to some resources or projects to learn more?

Thanks in advance!

Answer 1

I guess you mean a Ruby debugger implemented in Ruby. A good place to start would be to take a look at the introspection and reflection interfaces documented here

If you want to be a bit more adventurous you could look at the source for ruby-debug

Answer 2

A simple introduction into debuggers: http://t-a-w.blogspot.com/2007/03/how-to-code-debuggers.html.
It even has a small part using ruby hashes as an example.
