Hi all,
My immediate need for a response to the message below has passed, but I'd still
like to know for next time, at least if my idea of a solution was accurate.
Anybody?
Thanks,

I always thought that an implementation of FGL would be nice.

Some improvements to DrRacket's "automatic parentheses" mode are now
available in the nightly build version and git repository. If you have
previous tried auto-parens and abandoned it, or if you have never tried it,
please do try it now!
In auto-parens mode, typing a closing parenthesis will skip
I have some code that's been broken somewhere between 5.1.1 and git
HEAD. The issue seems to be either that circular lists no longer are
considered lists by `list?', or `in-list' has added a `list?' check (and
circular lists were never `list?').
In any case, these are the kinds of things I wo
Ciao a tutti,

executable appears to be dependent on the (single) original sourc

Ah, yes, that's right. We don't have a documented programmatic interface.
demod will be more useful shortly, at which point we'll do that too.

You just do:
"raco demod file.rkt"
and get back
"file_rkt_merged.zo"

What version of Racket are you using?
In particular, you should read the documentation for request-bindings.
In the past, it only read GET queries, but then it started to read
POST queries too.
If you are on 5.3.1, then it is an error with that change and you
should let me know (perhaps with a PR
I have a half-finished graph library based on the C++ boost library

Your test looks right, and I get similar results in Mac OS X in 64-bit
mode.
I haven't particularly tried to make foreign calls go faster, so I
expect there's room for improvement. A quick profile suggested an easy
way to trim 1/3 of the time, so I've done that (pushed to the git
repo).

Yes, there are 64bit builds for Mac and Windows. See the download option for

Hello,I am new to Racket. Currently I am evaluating it to find out if it works good enough for my work.One of important aspects for me is efficiency of Foreign Function Interface.Unfortunately, it seems that FFI is quite slow.Please can you tell me if this is a bug in my code or FFI itself is slow?
Hello,
I'm working on a racket buildpack for use on Heroku (again -- I tried
and aborted it about a year ago) but have noticed that the size of
Racket and startup time in racket applications suffers quite a bit

I currently have the old version of this software (Dr. Scheme) downloaded in my
computer classroom. I am getting a new lab and I want to install the new
version on those machines. My tech department has asked me to find out whether
the software is 64 bit compatible.

Graph algorithms are often meant to be very fast, and different algorithms
necessitate different representations. Two popular representations are
adjacency lists and shared structures. It also isn't right to call them lists

It would be nice if PLT would bless a graph representation. Such
