It would have been interesting to see what you tried. The simplest thing I could think of worked fine. Here's a little database app: #lang racket/base (require web-server/http web-server/servlet-env web-server/dispatch) (define (writer s) (λ (op) (displayln s op))) (defin

[racket] web server: CRUD put/delete?

Hi all, I'm using 6.0.1 trying to implement a CRUD interface, but the dispatch-rules doesn't seem to recognize PUT or DELETE as valid methods - they both are interpreted as GET. Is dispatch-rules limited to HTML 1.0 (i.e. only GET, POST and HEAD)? Has this been updated since 6.0.1? The cur

[racket] when is `listof` the better contract

In what situations should one prefer the `listof` combinator over an equivalent predicate contract? For instance, it seems to me that: (λ(x) (and (list? x) (andmap pred? x))) is a more-or-less equivalent way of saying this: (listof pred?) But in my experience the predicate version is always s

Unfortunately those options wouldn't help because I ran across this issue where an extension to Typed Racket I was working with was using splicing-syntax-parameterize "under the hood" to provide some interesting extensions. I would prefer it if those extensions didn't prohibit use of : within them

Re: [racket] Curious error messages

You can run racket under gdb and use a catchpoint to break when a certain system call is executed: https://sourceware.org/gdb/onlinedocs/gdb/Set-Catchpoints.html (make peace with 3m by issuing 'handle SIGSEGV nostop noprint' before 'run') You could then deliver SIGTERM to the racket process to c

No, I don't know of a way to do that, and I'd be surprised if there was an easy one (ie, one that I have remotely the low-level knowledge to implement). But someone who knows more about the system level might have better ideas. Sam On Thu Dec 04 2014 at 12:01:30 PM Robby Findler wrote: > Do you

Do you know how to get the racket-level stack at the point strace reports a call to open() or write()? (I do see this bug occasionally but not reproducibly so setting up something on my machine with more debugging output seems likely to be productive.) Robby On Thu, Dec 4, 2014 at 10:34 AM, Sam

Thanks for the insight guys. Fortunately I've solved my problem by adding a 1 pixel bitmap. going down the rabbit-hole of trying to fix the underlying problem in the Cocoa widget is beyond my skill. Stephen On Thu, 4 Dec 2014 at 11:48, Neil Van Dyke wrote: > Antony Blakey wrote on 12/03/2014 10:
