Hello,
I was trying to compile Racket Textual from source in a Webfaction's shared
host machine. It's running CentOS 5.6.
After downloading and extracting the tarball, cd racket-textual-5.1.2/src/;
mkdir build; cd build; ../configure; make:

We have a use for `port-try-file-lock?' that needs to wo
Hi again,
Thank you for the quick and helpful response!
This is a bug; it should give you roughly the same error as above, but
for the different reason. The problem is that we'd need to check
*every* element of the sequence to make sure it had the right type,
which a simple predicate can't do

They also did a presentation at GDC '09 about scripting a video game
(Uncharted 2) in Racket/PL
That sounds like something that would be good for planet 2.0, but it
seems complex enough that probably it won't get put into the current
incarnation of planet, at least in the short term.

Testing Nadeem's new PLaneT package in the spirit "I'll just *quickly*
try the first example, I was a little annoyed that I had to wait for the
documentation to build, before I could get to the action.
Is it be possible to let DrRacket build PLaneT documentation in the
background?

I was looking at the CUFP program and I saw that the video game
company Naughty Dog will be talking about using Racket in their game
development.

Don't apologize, I'm very grateful for your help :-)
I'll take a look at the paper and the documentation

Well, continuation-marks are a lower-level, lighter-weight construct
than parameters.
Sometimes you have to use parameters because that's the api you get to
work with (current-output-port being a popular example of that) and
sometimes you have to use continuation-marks because that's the api
you g
I'll try that in my particular case, however, what is the main difference
and how do I decide whether to use continuation marks or parameters?? what
are the advantages/disadvantages of choosing one over the other?
Thanks

Hi,
I recently discovered Typed Racket and am having a lot of fun with it.
Occurrence typing is pretty amazing.
I've stumbled across a couple of problems when trying to use
dictionaries and sequences, though. In particular, I'm currently
having trouble defining a predicate for the (Sequenceof A

Well, as I said, I'm pretty new to Racket, but so far there are two

extensibility, which is very well covered in the article now. The
second one (always IMHO) is that, a part from having a solid

Hi Matthew,
thank you for taking the time to explain it in such detail. I believe I'm
atleast closer to grasp the consepts of module and eval now. I've already
understood earlier that the top level namespace is a potential place for
collisions, and I can see it better now why it is so. I will
