[mac-lisp-ide] OpenMCL debug output on arbitrary stream?

[Duncan Rose]

I'm not sure this is the right forum for this question; here goes 
anyway.

I'm still slowly working on a Cocoa back end for McCLIM. The back end 
is now at a stage where it can run the McCLIM Listener well enough 
(almost!) to be used as a tool to help development. I'd like to be able 
to get the break loop displayed in the Listener (this would be more 
convenient than switching between the McCLIM Listener and the terminal 
/ openmcl cocoa listener when errors occurred).

However, I haven't got any ideas on how I'd achieve this. I know this 
is done in the OpenMCL Listener, but I can't see where.

Can anybody provide pointers on how to do this or where to look for an 
existing example where it's done?
