It's a known issue. Alex Knauth has submitted a rough solution to my fork
of it; I'll get it merged and pushed to the server shortly.

I get errors when trying to type in a multi-line function. Am I doing

Hi Martin,
As an example I implemented the standing wave animation.
The MetaPict package is available through the package system.
Use the package manager in DrRacket to install install it.
The run the program below in DrRacket to see a standing wave.
The documentation of the MetaPict package is
J and I chatted a little and he got his DNS working and also I added
http://try.racket-lang.org/
as an alias for it.
In general, the Racket team is willing to give out subdomains of
r-l.org for projects that would like them, so they don't have to buy
their own DNS addresses. Just email the list
I was looking through http://en.wikipedia.org/wiki/User:LucasVB/Gallery
(generated, according to the author, with a combination of php and libgd),
and wondered if anyone was doing similar stuff in racket. I'd love to see
code samples if so.

Hi guys,
Apparently, with a desire to use keywords more in functions, I’ll have to wrap
my head around keyword-apply better. Two questions I have are:
1. Why must the kw-lst be sorted in keyword kw-arg …)
After playing around a bit all of the following are equivalent:
(define (bar #:x x #:y y
Turning things back and forth between values and lists is not
something that our apis and our runtime infrastructure really
encourages. So I'd say that the first thing to try would be to either
fix the number of values returned from the function or to start
programming with lists instead.
If that
Is this what you are looking for?
#lang racket/base
(require (for-syntax racket/base
syntax/parse
racket/provide-transform))
(define-syntax test-pred-out
(make-provide-pre-transformer
(λ (stx _)
(syntax-parse stx
[(_ b:id p:expr)
As far as I can tell, there is no contract form that allows treating
the values returned as a list. Here is how you could implement one if
you wanted:

Maybe Robby has an opinion about whether this should be done in racket/contract

Pict should be making them just the same and they should convert fine
even if the GUI libraries aren't yet required. For example:

I had not actually heard of Xvfb before now, but that could be a good
solution. I balk at using full X11 with only 512MB of RAM, but that
could be enough to satisfy the original code's expectations. I will
have to experiment with it.

If you run it inside a BSD jail, that should take care of a lot of the possible
issues...
But you're right, of course. It should be able to run without X.

That does sound an awful headache for something that otherwise doesn't seem
to be using X for anything other than dependency expectations. It seems
like there should be a non-X-dependent way to do it.
