Hello Racket Developers,
I thought I would write a quick note about building Racket on Mac OS X 10.6.8
with the new clang compiler (the new front-end to the LLVM compiler backend
that is becoming the standard compiler on Mac OS X for XCode 4 and later).
Overall, it's been a good experience. A
Hello all,
The attached patch against the current git master adds an flvector-copy
procedure (along with docs and tests); it's simple, but nice to have in the
flvector library. Let me know if there are any issues with including this in
racket.
Thanks,
Will

FYI, I've submitted a bug to the bug tracker detailing this problem.

Huh. Or maybe it's option 4: system/OS dependent. I'm
Hello developers,
I've been compiling Racket from git a lot lately (working on some iteration
forms that now appear in the repository---thanks Sam!), and each time I do, I
run the test suite. For the past few weeks (month?) I've been getting a lot of
errors related to the contract system. I t

If I understand things correctly, the short answer is "fancy hardware." The

Matthew,
Thanks very much for the comments. I'll get to work preparing an updated
version using #:size soon, and send it to Sam for pushing. As for the issue of
a #:size that doesn't match the length of the iteration, I have been thinking
about adding a check inside the loop (for sizes that a

Hello all,
I've been thinking for a while about putting together a PLaneT library of some
iteration/comprehension forms that I often use that are not found in the racket
core. Right now, I have a small it-comp.plt local PLaneT package that contains
for/vector
