Do you mean something like this?:
(provide (rename-out [-#%module-begin #%module-begin]))
(define-syntax-rule (-#%module-begin form ...)
(#%module-begin
(module configure-runtime racket/base
(current-prompt-read

I think a `configure-runtime` submodule (in the expansion of any module
using the language) is the right place for this kind of configuration.
The `configure-runtime` submodule is similar to `main`, it that it is
only used when the enclosing module is the main module of a program.
Instead of a di
Is there a way to specify a reader for the repl for a language?
One bad way to do this would be to modify #%module-begin to include
(current-readtable (make-readtable-for-my-lang))
or something like that.

This worked — for some reason, moving the '(file ...)' expression into the
`with-syntax` expression made a difference.

I know that a hard-coded absolute path can be used in `require`:
(require (file "/path/to/directory/module.rkt"
But how can a generated path be used? Like so:
(require (file (path->string (build-path (current-directory) "module.rkt"
In particular, I want to `require` the file if it exis
I pushed a fix.
Thanks for the report!

Hi all,
I wonder if anyone has experience in or pointers to using Racket with
OpenStack? Particularly, I'm currently interested in client-side object
storage (Swift) interfacing and server-side middleware scripting.
E.g. I'm trying to figure out the most efficient way to PUT/GET Racket
objects s
This has been fixed in the pre-release version of Racket:
http://pre.racket-lang.org/ and will be included in our next release.

Hi there,
I stumbled upon this thread when searching for generics. I really like
Alexander's solution, but if I understand it correctly, the my-match-lambda-
append function should read something like:
(define my-match-lambda-append
(case-lambda
[() (case-lambda)]
[(f1 . f2) (lambda ar
