Try emailing admin@common-lisp.net. Support is excellent.
...is about to happen, but I do not want to give it away. Hint: I got
into this because I decided the Cello web page needs an animated GIF,
not screen shots.
I guess that means the page won't be ready in the foerseeable future? :-)
Smart guess. :) But I really do hope to do it today. Draft of some
random text is attached. Hope you can read RTF. If not I will send it as
plain text. Maybe you can help me refine it...what can I leave out, what
more would you liek to know?
In that case, I'll stop lurking waiting for the page and rather ask some
questions here...
- What *is* Cello about, really? Is it a GUI, a GUI toolkit, a 3D took-
kit or all of the above? Text will do as an answer, I suppose.
All of the above? It is not like some GUIs where you get a fixed
framework you have to learn and live with, although it will offer as
much out-of-the-box productivity as those. Cello is just way more
flexible. Once people see the source for my widgets they will get the
idea and probably invent their own (in typical Lisp fashion).
- I only have access to SBCL/CMUCL on Linux or Lispworks on Solaris; are
there any hope of getting something to work with a moderate amount of
work?
Absolutely. It already runs on ACL/win32, LW/win32, and ACL/Linux. You
need recent patches to CMUCL/SBCL to handle callbacks from C into Lisp.
See if you can get on the mailing list (which I will CC on this message)
where a few folks are puttering around with cmucl/sbcl. (Not much news
lately, tho, so it might be your turn at the plate.)
I had some vague idea about making some funky 3D GUI using Glut and Common
Lisp a few months ago, but it faded before any code was written. This is
why I'm interested in the Cello project..
Well it's working like a charm so far. Just gotta do more widgets and
then it is up to others to do more ports. I will eventually do an LW/OSX
port if no one else does. Right now I am stalled because I am having fun
creating a killer new capability for Cello. I guess I am easily
distracted. :)
