Ruby Debug Basics
Figuring out what’s wrong in Ruby can be a pain. That dynamic typing that you find so nice while writing code can sometimes work against you when reading it — and troubleshooting it. What most of us end up resorting to is basically one step up from how most JS debugging happens: puts.
While this is annoying, it doesn’t have to be this way. Ruby comes with a debugger, but it is slow on non-trivial applications. The best alternative is a gem called Ruby Debug, which is fast and has a bunch of goodies. I come from the GUI-debugging world of VS.NET and IDEA, so getting into Ruby Debug was a little bit of a challenge for me at first. If you come from the gdb world you should feel right at home.
