First of all, happy new year everybody!
Hi Gus,
As a matter of fact I just recently started work on this.
You can follow/contribute development at:
http://github.com/alloy/rucola/tree/macruby
However, quite some work still has to be done.
I'm rewriting almost all parts of rucola, on a needed basis, as we
port our application to macruby.
During this process quite some bugs are being discovered/tracked and
fixed in macruby,
and rucola will finally be smoothed out to co-exist with macruby (and
hotcocoa) and a version 1.0 release candidate.
So it will take some time, but it will definitely pay off for both
rucola and macruby.
Cheers,
Eloy
