Hi Pual,
I sometimes use GDB when I need to debug RubyCocoa/MacRuby
_themselves_, as they're written in C. For Ruby code, however, I
almost never need a debugger.
Maybe it's because I write most code test driven so I know that the
code is probably ok when I actually use it. In the cases where it
didn't pan out as expected, I use print style debugging or ruby-debug
(RubyCocoa). For a more elaborate explanation, please see the testing
video of Manfred explaining about it at the Ruby on OS X conference: http://www.fngtps.com/2009/06/ruby-on-os-x-conference-videos
We have a fairly big RubyCocoa app and some of our Rails apps are
really big.
It's unfortunate that ruby-debug doesn't work on MacRuby, but Laurent
has already announced that at some point in the future work will be
done in this area. But at this moment, MacRuby itself still needs lots
of work. So we'll need to have a bit more patience for a real debugger.
HTH,
Eloy

if one wants to help... patches are always welcome.

Hmmm. Lack of debugger support is surely a serious limitation. A
deal-stopper for any complex real-world app I would have thought.
I guess you're aware that this will eventually be needed.
Is anyone using MacRuby for a large project? How are they coping
without a debugger? (I'd like to know since I'm planning to convert
an old non-Objective-C app to MacRuby).
