Thanks for the example! I did not guess correctly about your mixture of
embedded modules and `dynamic-require`.
The short answer is that you should either embed modules or reference
them through an external paths like "/Applications/Racket
v7.7/collects", but not both. Otherwise, the two worlds co

I put up a repo with the bug at https://github.com/nwg/racket-expo
The stack trace is this:
build-path: contract violation
expected: (or/c path-string? path-for-some-system? 'up 'same)
given: #
context...:
do-raise-argument-error
loop
build
proc
call-in-empty-metacontinuation
I don't know if it helps, but config:installation-name is a promise defined
by setup/private/dirs.

Awesome, thanks!
I actually just implemented it with the roundabout callback system, i think
i might try out your suggestion though.
Thanks for working on racket!

I'm not sure how it could be in `dynamic-require` itself, as opposed to
a library that is loaded by `dynamic-require`, but it sounds like a bug
at some level. Can you provide a small example?

I see that there's not a good way right now, but here's a workaround
that uses information about the current layout:
A cpointer value is implemented as a Chez Scheme record with either 1
field or 2 fields. There are 2 fields only when the cpointer has an
offset as a result of `ptr-add`, so you can
A bit more context:
I am using a communications library (zeromq) and i need to share a c
context object between c and racket for in-process communication.
I can either create it in c or create it in racket. The library i'm using
happens to create it in racket.
The only way i know of solving this
I had a question. In embedded racket, I am passing a _cpointer value back
to c code by way of racket_apply's return value.
Looking over https://docs.racket-lang.org/inside/cs-values_types.html ,
there appears to be a group of functions associated with extracting values
from ptrs. I do not see one

Ye. I think that's a good and useful topic to showcase! Please send

Sam, thanks
To be clear, this crash happened DURING a dynamic-require and judging by
the stack trace looked to be part of the dynamic-require machinery (and
this seems to depend on the installation name).
I actually wasn't depending on anything but racket/base, so i don't believe
anything i was u

Hey, everyone,
I am organizing a series of Online Lisp Meets that started after this
year's electronic European Lisp Symposium. The mailing list is at

My guess, not having looked further than your email, is that when you don't
include racket/promise, something is supplying a promise to something else
but there are two different instantiations of the promise library, causing
the force call from one not to recognize the promise from the other. Then
Hello.
I noticed something and was wondering what the list thinks:

don't include any libraries (for a very bare bones c file) i have problems
with a crash on a promise on any dynamic-require:

It's currently not intended to work for packages installed in user
scope --- only for packages in the main installation --- although
probably it shouldn't report a path error for a user-scope package.
I'm not sure how difficult it would be to make redirection work on a
user-scope package's documen

I tried
```
(define-syntax my-file
(make-require-transformer
(lambda (stx)
(syntax-case stx ()
[(_ path)
(printf "Importing: ~a~n" #'path)
(expand-import #'(file path))]
(require (my-file "test.rkt"))
```
with the same result: no errors in require, but no import
18 matches
