[racket-dev] GNU lightning version
Hi! I hope I chose the correct mailing list for my question: are there any reasons why Racket currently uses very old version of GNU Lightning? According to sources, Racket 6.1 uses GNU Lightning version 1.2 which originates from 2004 and current version of GNU Lightning is 2.0 which supports many new back-ends, particularly MIPS. Is it manpower problems (there is nobody who can upgrade this component in Racket), technical ones or something else? -- Thanks, Yaroslav _ Racket Developers list: http://lists.racket-lang.org/dev
[racket-dev] How to translate DrRacket GUI to another (human) language?
Cheers, I need to create a Finnish translation of DrRacket GUI and error messages, starting from Beginning student level. How do I proceed and are there any guidelines for the internationalization of DrScheme? Yours, Antti Karttunen _ Racket Developers list: http://lists.racket-lang.org/dev
Re: [racket-dev] How to translate DrRacket GUI to another (human) language?
This file contains the string constants used by DrRacket: https://github.com/plt/racket/blob/master/pkgs/string-constants-pkgs/string-constants-lib/string-constants/string-constant.rkt It then grabs them from one of the language files like https://github.com/plt/racket/blob/master/pkgs/string-constants-pkgs/string-constants-lib/string-constants/private/german-string-constants.rkt You could create a file like this named finnish-string-constants and give it to us (we'd be happy to make the changes to the first file necessary to link it in.) It is best to start modifying from https://github.com/plt/racket/blob/master/pkgs/string-constants-pkgs/string-constants-lib/string-constants/private/english-string-constants.rkt because it is complete. I also believe (and Robby can confirm this) that any string translations you leave out will just remain in English, even if you don't include them in your constants file. I hope this process is not too painful and we are thankful for your interest in helping!

Re: [racket-dev] [plt] Push #29214: master branch updated
My best understanding is that the problem is that path-pkg is used by raco setup to tell whether unstated dependencies are present. If files from collects/ are in a package, then everything needs to depend on base (which is inconvenient) including other files in collects/ but the files in collects/ aren't part of a package that has dependencies and base isn't actually considered installed (at least during the collects/ part.) As mentioned, I also tried racket as the package, but that had a very similar (but slightly different) crash.

We've talked about creating a deeper hierarchy of errors than is shown in the manual: http://docs.racket-lang.org/reference/exns.html#%28part._.Built-in_.Exception_.Types%29 But it would be some painstaking work.

Re: [racket-dev] BUG: busy-waiting
Thanks! I've pushed a repair. At Thu, 4 Sep 2014 01:56:07 -0400, Marc Burns wrote: Yes. I forgot that, in the case I was debugging, `unzip` was wrapping its input pipe with `make-limited-input-port`. The user port created by `make-limited-input-port` is causing the loop. Here's an example: #lang racket/base (require racket/port) (define-values (in out) (make-pipe)) (define p (make-limited-input-port in 10 #t)) (write-bytes #hello out) (define buffer (make-bytes 1)) (peek-bytes-avail! buffer 6 #f p 0 1) The `do-peek` function in port.rkt:1027 makes a nonblocking attempt to peek from the wrapped port. When the peek is unsuccessful, it returns an event that is ready when the wrapped port is ready and whose value is zero. Thus, when the wrapped port has greater than zero and fewer than `skip` bytes available, `do-peek` is nonblocking. The call to `peek-bytes-avail!` then loops calling `do-peek`. I think that this could be resolved by returning (choice-evt (wrap-evt progress-evt (lambda(x) #f)) (wrap-evt (peek-bytes-evt skip 0 #f port) (lambda(x) 0))) instead of the wrapped port event at port.rkt:1027 Then again, couldn't `do-peek` just return the appropriate `peek-bytes-evt` when `count` is nonzero?
