Woops! Forgot to put the link to the repo in the original post. Here it is for
those interested: https://github.com/Freezerburn/Rhipmunk-Physics

I just wanted to let anyone know that is interested, the new FFI bindings
that I have been looking into for Chipmunk are now on Github. It is far
from finished, but there is at least an initial commit in the repository.
Currently it provides the API bindings that allow the simple
"hello_chipmunk.c"

Sorry if I just didn't get it right, but wouldn't it be useful to have
a conditional insert?
For instance, it would make sense

OK, thanks. I am unconfused now.

It's what `port-next-location' reports, which is the same as

I'm double-checking before I code this into an API. I see in

I'm considering writing an H.264 encoder/decoder in Racket. Has anyone tried
such a thing before?
Codecs require a lot of bit-whacking and the h264 standard is particularly
convoluted. Efficiencies are obtained in C in many different and usually
complex ways. Codec experts usually recommend

Thanks, it works great! Very interesting code, I'll have to read up on match
and friends. Looks like you basically took the grammar from the plist-dict
documentation and wrote a recursive-descent parser?

You can always try including the relative path. Something like:

Doesn't OS X have a .profile? Maybe try defining the path there instead of

I am starting to play with scribble and have tried to generate a pdf document

When I hit the Scribble to PDF button I got:

I'll have to look into what Jay wrote, as I didn't know it was possible and I'll
have to read the docs abit before I really understand it.

Maybe something similar to Microsoft's #region directive (

Ronald,
The Structure and Interpretation of Computer Programs has a pretty good
section about how the recursion happens. It's pretty short, and I think it
covers what you are interested in understanding

Hello Ronald,
Function calling is the semantically the same no matter what function you
call. When you call a function you set up an environment/stack for the
function to operate in.
Now when a function is recursive it create a new environment/stack and
calls a function just like itself (with equ

Hi,
would it, maybe as part of the current error message overhauling, be
possible
to make the error message for cyclic requires more useful.
It is currently truncated at an arbitrary length, that is often not enough
to
show a full cycle. That makes it unnecessary hard to track down these
