I'm clearly in over my head here, but I'm hoping macruby can

I've cobbled together an objective c framework with a class that
handles some IO Kit transactions. The framework seems to work with
objective c cocoa applications.
I would like to use this framework from macirb or a simple
standalone ruby script. The framework appears to load from macirb
and I can make an object and call it's methods. I can see packets
sent out the FireWire port as expected.
A key feature of the framework is accepting callbacks from IO kit.
Certain FireWire packets on the bus should invoke method callbacks.
The callbacks do not seem to make it to the objects created in
macirb or a simple script.
I'm researching run loops and threads and trying to understand if
macirb or macruby uses NSApplication and its run loop, but I'm not
getting very far and I may be way off base.
Neither macirb or macruby start the CF/Cocoa runloop for you by
default [1], so you will have to start it by yourself. You can call
NSApplication.sharedApplication.run or NSRunLoop.currentRunLoop.run.
If you do this from macirb it will block as expected and you won't be
able to evaluate expressions. I would then recommend using an irb-like
Cocoa app that already uses the runloop under the covers (like http://github.com/vincentisambart/hotconsole/tree/master
for example).
HTH,
Laurent
[1] but this will be fixed in the next-next release :-)
