[MacRuby-devel] MacRuby-devel Digest, Vol 22, Issue 62

I look forward to your book with impatience.  From the other stuff I have seen of yours, I expect that it will be both informative and literate.

May I put in a plea, hopefully before it is too late? Could you please either make mastery of xcode optional---which I would prefer---or provide a mental model for it that makes it coherent?  Every purported introduction attempts to lead me by the hand through a morass of totally unmotivated complexity while expecting me to be grateful for how it is simplifying my life.  It would be a great pity if the elegance of Macruby could only be appreciated after hacking ones way through miles of xcode underbrush.

> MacRuby is working out well for my application with the exception of error handling. I find that I cannot get a traceback of all errors even when I have a rescue pushed on the stack. Sending a message to an undefined class action causes a hang with no error message that I cannot recover from. Nor can I always get useful information from the "bt" command in GDB if GDB even remains running after the error.
