Actually I get good information from the regular SDL
list even though I don't really program in C at all. 
There are a lot of applicable discussions about how to
do blitting and updating rectangles, that sort of
thing.

The new version of PyAliens is pretty good for that. 
It would be nice to have a place for people to upload
things they've done with PySDL, I'd contribute to
that.

I'd like to play around with this.  It shouldn't be
too hard to flip the alpha channels on images as they
are loaded, right?

Just wondering... is there anything about python 2
that jumps out at you as being a big improvement?  It
seems pretty similar to 1.6 for such a big jump in
version number.

no, i'd wager not. when this got submitted into SDL
they mentioned SDL_image-1.0.10 was right behind it
so i never bothered. still waiting for it though.

well, Guido has mentioned a couple times that while
there's a lot of new features for the new python, the
2.0 has more to do with the status of the new ownership
of python (now owned by BeOpen). Guido also feels that
python gets some bad mojo for being a 1.x release
(heh, 10 years and still 1.5), so some of it is marketing
as well. a well defined list of changes is found at
http://www.pythonlabs.com/tech/python2.0/news.html.
those are the changes since 1.6. 1.6 mainly added
unicode and a new regexp module.
the current plan is for the official python 2.0 release
early next month (barring anything necessitating a
2nd beta or release candidate)

the good news is pySDL seems to recompile just fine
for the new release, so it will only benefit pySDL.
(although i noticed the Py_Malloc and Py_Free macros
were gone. didn't look into it, but quickly swapped
them out with malloc and free)
my testing has been admitedly limited to this point.

I have to dig through the archive for that list too when I have some
problems. Thanks for the hint!

Where can I have a look at it? It sounds a bit like the first think I made
with pysdl, namely a simple 'Space Invaders' clone. Great fun to program.
I assume I could find it on Google or Freshmeat, but surfing with 33.6kb
is a lot of antifun.

peter's right, i spend a lot of time here too. i do know
C programming, but pretty much all the pySDL functions
have a 1-to-1 call for their C function. pySDL is a pretty
thin wrapping, so techniques for the C SDL apply directly
to the python version.

currently, all pysdl applications i know of are open
source. the "examples" directory that comes with pysdl
is a bit frightening, and i've currently rewritten most
of those to be simple and elegent (and as a bonus, work
correctly). i'll be releasing that real soon, but for
i'd recommend the cleanedup pyaliens i did, and you can
also see cowtipper by Jeff Clement. I also recommend
David Clark's pyPanda, pyStars, and the direct-from-c-
conversion, pyAliens-1.1

the devel-pysdl archive lost my post?? here is a
temporary home for the cleaner pyAliens:
(note, this wasn't the exact version i put on
the mailing list recently, but it should be close.
i noticed it does print fps to the console as it plays)

well, if anyone's interested, i have a version of my
super-secret, unlreased source-split version of pysdl ready
as a binary release for python 2.0b1 (win32). i've been using
it for my testing and it works quite well. my big grief with
it now is that it's using the latest CVS SDL and the alpha-
slightly-incompatible SDL_image-1.0.9. so all image alphas
are backwards. it's a pain using images with alphas (for now)
but it does work with python2. if anyone wants, i'll post the
binaries.
