I'd like to nominate JazzScheme as an interesting and exciting new contribution to Lisp, but it hasn't been publically released yet. Not quite sure what they're waiting for, but hopefully we'll see something soon.

The sound from lispbuilder-sdl-mixer is flakey on Windows as well. The only stable platform for sound seems to be Linux. I'm going to blame the SDL_mixer library. Heh, yes, I thought this might have a hand in the problem :) I can actually get an mp3 playing; something just dies when I try to shut t...

OTOH, with Lispbuilder-SDL (I just started using these bindings a couple days ago, and they seem good) you have all you need to write a game of some description. I've had a little trouble with it on my Mac (e.g. the audio code crashes in my simplest test programs for some reason, perhaps due to how...

Right now, I am working on a graphics library that will hopefully make for interesting applications.

What about image files then?

Thanks guys, this makes sense

Does that mean they're more flexible than normal regular expressions - they can classify context-free/sensitive languages?

Ahh, we can do that? I wanted that a couple of days ago and ended up writing "(if (not (null ...)))", which smells. Funny, I used to use "if(x)" in C/C++ quite often.

Hi, in your code you have: (CONS ((CAR X) (incr (CDR X) 1))) CONS takes two arguments, but you've wrapped them up as one (a common mistake when coming from a function(arg1, arg2)-style language, and one I make as well): (CONS (CAR X) (incr (CDR X) 1)) With that removed I can compile and call the fun...

The real apply in SBCL is defined somewhere else. AFAIK, it should be defined in sb-imp package. I'm not familiar with sbcl internals, so I might be wrong. I had a look for all definitions of apply, but haven't found another one yet (there's a %apply and interpreted-apply or something, but they see...

Only the compiler knows how to call the function (because function is usually compiled to byte code or machine code), so it is not possible to write apply in CL. I had a quick look at the SBCL source and found apply in eval.lisp , line 279 - search for "defun apply". :) Note however the c...
