Re: [racket] "raco pkg update" doesn't work

Now updated... I didn't do anything. Is there a timeout for updating checksum in Racket? Fri, 13 Jun 2014 11:32:59 +0400 от Roman Klochkov : >I try >$ /usr/racket/bin/raco pkg update binary-class >Resolving "binary-class" via >http://download.racket-lang.org/releases/6.0.1/catalog/ >Resolving "

Re: [racket] "raco pkg update" doesn't work

When you install via the package catalog, i.e. with the name "binary-class" rather than with a github URL directly, then you use whatever the catalog has as the checksum, which is updated roughly every hour. (You can go to the site and request an update for your packages with the "Update" button)

[racket] How to implement declations in an internal definition context?

Hi All, In order to add linear equation syntax to MetaPict I need to understand how implement declarations in an internal definition context. For practice purposes I have written the following small program. So far global declarations and local declaration via a let-var binding construct works. I

[racket] racket install on NetBSD provider?

I just joined a shell provider (sdf.org) that's running 64bit-NetBSD. I want to install Racket to my local directory. Do I need just the raw source? LB Racket Users list: http://lists.racket-lang.org/users

[racket] pass pattern vars as syntax-class args before they appear in syntax-parse pattern

I want to do something like this: #lang racket (require syntax/parse) (define-syntax-class (myclass . args) (pattern x:id)) (syntax-parse #'(a (b c)) [((~var x (myclass #'(y ...))) ... (y z) ...) #'(x ...)]) But this doesnt work because I'm trying to pass y before it is bound. Is the

[racket] Racket for Lego Mindstorms EV3

Hi all, I intend to teach programming and robotics for my ten years old daughter. I want to use the Lego Mindstorms EV3 that contains an ARM9 processor. Is there any version of Racket generating code to EV3? Or maybe another Lisp or Scheme dialect? Thanks in advance for any answer. Cheers

Re: [racket] racket install on NetBSD provider?

Looks like their entry-level account ("http://sdf.org/?join";) has a 200MB disk quota, which probably is not enough for a full Racket install (my Racket 6.0 GNU/Linux install takes 525MB). But their VPS accounts ("http://sdf1.org/index.cgi?vps";) could handle that disk space. Or, maybe stripp

[racket] Convert ASTs to Control Flow Graphic

Re: [racket] pass pattern vars as syntax-class args before they appear in syntax-parse pattern

Thanks. That works, but it leaks the syntax class abstraction a little bit. I figured out I can also get the behavior I want with ~peek On Fri, Jun 13, 2014 at 3:27 PM, J. Ian Johnson wrote: > I use ~and patterns to first match structure and then match syntax classes to > do what you're doing.

Re: [racket] Convert ASTs to Control Flow Graphic

It depends on how precise you want the graph. I can give you a complete graph given an AST and have it be a sound abstraction, but it won't be useful. Otherwise what you're asking for is something like 0CFA. I have to reiterate that you need a semantics for your ASTs to really make sense. For th
