I visited the home page of the project and read there that it is frozen.
Does that mean that there isn't much more to do, or that you have lost your
interest in developing it? I am asking that because I really liked the
library, specially that it is a high level API, and I have a few ideas. But
before exposing them I need to know the library itself.
So I would like that everything was documented, even if the documentation is
only in the functions themselves, or maybe only at the home page. I can
help, but, you know, the library wasn't developed by me, so I think would
take too long to do this alone.

Cheers
Gustavo

The project itself is not frozen, only the current API, intention being  
that it would stay mostly the same for 1.x releases. As for 2.x versions,  
I'm not yet sure what those would be like.
Release 1.1 would be current cvs head with some fixes and improvements I  
have in mind. It is just that I was a bit busy with other things for a  
while and didn't that much time to work on it.

Actually I've been working more with PAL lately (playing with the Chipmunk  
2d physics library  
(http://www.slembcke.net/photos/v/programming/chipmunk/), it could make a  
nice add-on package for PAL :) ) and an integrated gui is probably  
something I'm going to work on next. That and the documentation...  
Meanwhile, I'm glad to answer any questions anyone might have in this  
mailing list. Actually some kind of FAQ/tutorial thingy might be nice, so  
if there are some specific problems that anyone is having/had please let  
me know.

So, if you are asking if PAL is dead the answer is the old "no deader than  
usual" and I'm still interested in any ideas you might have ;)

I've been looking at this library as well, for integration into lispbuilder.

So far Chipmunk seems great, it is quite fast and seems to work fine with  
CL. I would recommend it to anyone who wants an easy way to add some 2d  
physics in their games. So far I have only played with the features that I  
immediately need but full bindings shouldn't be a big job.
Only problem is that it would need some C glue since it uses a lot of  
structure values as arguments and AFAIK CFFI doesn't support those.

And of course it would be nice to have something similar written in CL...

I would probably sign up for a C->Lisp rewrite of Chimpmunk.

Subject: [Pal-devel] Beginnings of PAL-GUI
Message-ID: <op.tz9d97sfu6rk5c@otto>

Just to let you all know I recently started developing a gui library for  
PAL. For those interested you can get it from the cvs with usual means,  
module name is 'pal-gui'.

It is still very much in infancy but there are a few widgets that sort-of  
work (at least after I work a few more hours on it) but I think it should  
be wholly usable within a week, if nothing surprising happens.

Subject: [Pal-devel] PAL v1.1 & PAL-GUI v0.1 released
Message-ID: <op.t02paekg53cznb@otto>

PAL v1.1 was just released. Unfortunately I needed to make a few changes  
to the api that might break something.
Most important changes from v1.0:

- Name changes; reset-blend-mode => reset-blend, circles-overlap =>  
circles-overlap-p,
   point-inside-rectangle => point-inside-rectangle-p, point-in-line =>  
point-in-line-p.

- Added color.lisp, WITH-BLEND now uses COLOR struct instead of a list of  
rgba
   values. By v1.2 all rgba arguments will be replaced with COLOR.

- Removed CURRY.

- Image drawing should be much faster under certain conditions.

- I finally started working on the manual...

PAL-GUI is slowly approaching usable state (I hope...). Currently there  
are still some look and feel issues (clipping etc.) but there are already  
a few working widgets. Naturally, it is not documented yet but there are a  
few examples and it shouldn't be too hard to use. Basically it is just a  
regular windows/widgets/callbacks gui implemented in pal and integrated  
with its event loop.

Currently on my todo list for v1.2:

- Few utility functions for using PAL with Imago  
(http://common-lisp.net/project/imago/), for screenshots etc.

- Real drawing primitives would be nice, proper polygons and lines, svg  
importer etc. Currently PAL's draw-* functions map fairly directly to  
OpenGL and are quite limited (and slow).

- Batched image rendering for extra speed. Kinda like improved draw-image*.

- TTF support.

- Possibly merge pal and pal-gui.

- Documentation. Always the last one ;)
