Not really necessary: the textual distribution is the core one (it
isn't really a core at the moment, but it will be more core-ish); the
gui (core) distribution is much bigger s
Ah- I missed your post on April 28.
Further thinking on the issue, I'm inclined to let the user specify a
path to the executable as a configuration setting - or even include
the major platform executables in the plugin - and just avoid
burdening users with scripts.
Cheers,

I've been upgrading some of my programs from 4.2.5 to 5.0.1; I'm
looking at changes to the output of compiler/zo-parse, and I see that
a new field has been added to the let-one called 'unused?'. In what
situation would 'unused?' be true?

Good catch. I just pushed a fix.

You probably have to define your own formlet, e.g.:

I'm trying to construct a simple tax calculator in Racket for use over the web.
Here's my code so far:
#lang web-server/insta
(require web-server/formlets)
(define new-post-formlet
(formlet
(div "Amount: " ,{input-string . => . amount}
;,(select-input '("Net" "Gross") . => . type)
Well, the following program
#lang racket
(for ((log-length (in-range 23)))
(let ((length (expt 2 log-length)))
(printf "Applying append to list of ~a singletons~%" length)
(time (apply append (for/list ((i (in-range length))) (list i))
Runs fine for me---the final stage reports

Try it out and see. I believe that the below is considered a common
idiom and that Matthew has probably done some work to make it work
well, but the contribution of a stress test is always welcome.

Hello all,
I recently encountered some library code of the form
(apply append list-of-lists)
where list-of-lists could be essentially arbitrarily long (i.e. list-of-lists
came from clients of the library, and therefore could be anything). I didn't
try to break it, but it made me a little nerv

This came up before and the environment.plist is mentioned in many
places as the proper solution. It seems that Apple introduced
/etc/paths.d for this but you found that it is not sufficient for GUI apps.
OTOH a simple (getenv "PATH") returns the same things as echo $PATH in a
Terminal window.

It is part of racket. The text% class does what he described.

Hi,
This isn't actually a problem with racket, but just a helpful tip for OS X
user who want to use the racket system commands for exectables they have
installed themselves. (I found it looking at the documentation for an OS X
GIT tool)
My problem was I couldn't get (system command) to call newly
