I can swear I had this working great the other day but I don't remember doing anything special to make it happen. Anyway, here it is: I'm using AllegroServe and when one of the server threads drops into the debugger I want--of course--to be in an sldb debugger. I've given AllegroServe the magic incantation (net.aserve::debug-on :notrap) which causes it to let unhandled errors drop us into the debugger but I'm just getting to Allegro's debugger in *inferior-lisp*. I've got: #+allegro(tpl:setq-default *debugger-hook* #'swank:swank-debugger-hook) In my ~/.swank.lisp for whatever that's worth. What am I spacing on? -Peter -- Peter Seibel peter@javamonkey.com Lisp is the red pill. -- John Fraser, comp.lang.lisp
