You can find the license that Racket is released under here:
https://download.racket-lang.org/license.html
This page points out that Racket is released under the LGPL (rather
than the GPL), and also says:
First, if you distribute your Racket application in source form or as
compiled bytecode file
Do programs written in Racket that use the libraries of racket-lang.org's
implementation need to be licensed under GPL terms? Much like it is the case
with e.g. the libraries in AdaCore's Ada implementation?
Or is there a "Runtime Library Exception" or a "Classpath Exception" or
similar, like i

Hello All,
We are in the process of submitting a Google Summer of Code
application for Racket. If you have an idea for a self contained
project that would benefit the community, please let us know. These
should be projects that a student would be able to complete in about 3
months.

Generic path sounds good. When I sent the first message I didn't think
through how to set the flags for #%module-begin, but I'd definitely use a
config file with a generic path (unless there's a way to set compile-time
parameters from the command line).

I like your idea, but unless I misunderstand, I'd still end up with a value
(namely the module-picking condition) that I have to influence from afar (to
produce different results when the #%module-begin runs).
But it suggests another idea, which is to have the #%module-begin load a
generic rela

Could you put the dialect values in separate modules and have the
#%module-begin conditionally pick which dialect modules to require?

It is probably best of all modifications to the gui objects happen on the

Yes, around 80% of the time if I disable macro hiding, and sometimes even with
macro hiding if I’m moving back and forth through a long sequence of steps.

This is part of a larger pattern where I've got a basic `#%module-begin` for my
#lang that I want to spin out into dialect-specific versions. The dialects only
vary in certain values.
Sure, I can make a

Hi again,
I just realized that I never figured out how to get radio-groups not to
raise an error when no option is selected. I manage to put defaults for
input-string and so on, by doing what Jay suggested and redefining my own
through the use of 'default and 'input.
In the case of radio-group, w
