[racket-users] Package server broken, at least five hundred intro cs students affected!
Could we figure out: 1. What's wrong with the package server's indexing of updated packages, so my students can proceed. 2. An official channel to report problems with the package server. 3. If funding specifically earmarked to support monitoring of and feedback from that channel, fixing of issues, and general reliability work, would help, because I would be happy to contribute some of my professional development funds to that.

Re: [racket-users] Mysterious issue with pict/code
This definitely seems like a bug.

[racket-users] Mysterious issue with pict/code
I spent a few hours tracking down a mysterious bug. Although I've fixed it, I still don't understand it. I would appreciate some insight from those who understand these things better. Here's the simple reproduction: *main.rkt*: #lang racket (define-syntax (test stx) (dynamic-require "./other.rkt" #f) #'(displayln "HI")) ;This is fine (dynamic-require "./other.rkt" #f) ;This triggers the error (test) And *other.rkt *is simply*:* #lang racket (require pict/code) The error when running *main.rkt* is: no module instance found: # 0 context...: namespace->module-namespace82 copy-namespace-value temp250 for-loop [repeats 1 more time] perform-require!78 /Applications/Racket v7.4/share/pkgs/compatibility-lib/mzscheme/private/ old-procs.rkt:47:4: make-namespace .../racket/unit.rkt:996:20 "/Applications/Racket v7.4/share/pkgs/pict-lib/pict/code.rkt": [running body] temp37_0 for-loop run-module-instance!125 for-loop [repeats 1 more time] run-module-instance!125 apply-transformer-in-context ... It would appear that the dynamic-require of a module that requires pict/code fails inside a macro, but not otherwise. What's up with that? --Stephen -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

[racket-users] Re: Some guidance in setting up Racket as a game scripting language.
I get that it's probably not the best way of doing it, like I described it. But this is mostly a project of brushing up on C and more low level programming. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
