Re: [racket] Error with pict3d

You're not doing anything wrong. Pict3D requires OpenGL version 3.0 or higher to function, and it looks like your computer doesn't have it. To find out for sure, here's what you can do: * Mac OS X: Check the OS version number. You need 10.7.5 or higher. * Linux: Run glxinfo | grep "ver

[racket] Nearly all of the functionality from the 2htdp teachpacks is now available in 2htdp-typed

I’ve had the 2htdp-typed package available for a little while now, which is a Typed Racket wrapper for the HtDP/2e teachpacks. It was missing big-bang, since it is implemented as a macro, but I have now added support for big-bang in Typed Rack

Re: [racket] Looking for better designs to learn principles.

There’s also the thrush function from the point-free package, which uses the argument order of the threading macro while providing the functional style of compose. http://pkg-build.racket-lang.org/doc/point-free/index.html?q=thrush#%28def._%28%28lib._point-free%2Fmain..rkt%29._thrush%29%29

Re: [racket] Looking for better designs to learn principles.

If "thread-through macro" refers to " http://www.greghendershott.com/2013/05/the-threading-macro.html"; then I recommend a functional alternative called "compose": (define print/cdr (match-lambda [(cons x xs) (print x) xs])) (define print-two (compose print/cdr print/cdr)) The result is

[racket] Portability of .zo files

(I'm playing with some optimizations, so this is a theoretical question to understand some parts of the Racket implementation, not a real life problem.) Can I move a .zo file from a machine that has extflonum enabled to a machine that has extflonum disabled? Can I move a .zo file from a machine t

Re: [racket] scribble and .gitignore

While I'm writing documentation, I often use DrRacket to generate HTML, and -- at least, with my configuration as-is -- it creates files in the same directory where the .scrbl files are. Is there a way to change the destination directory used by DrRacket's scribble mode? On Sat, Mar 14, 2015 at 2

Re: [racket] scribble and .gitignore

Ignoring "compiled" is right, but documentation goes to "doc". The "compiled" and "doc" directories should cover all files that are generated by Racket tools. At Sun, 15 Mar 2015 02:33:10 +0800, WarGrey Gyoudmon Ju wrote: > I use ./compiled as the dest directory so that all generated files can be

I use ./compiled as the dest directory so that all generated files can be omitted in .gitignore once and for all. On Sun, Mar 15, 2015 at 1:30 AM, Jon Zeppieri wrote: > I've been looking at the .gitignore files in various racket packages, > and the ones I've seen don't ignore files generated b

[racket] scribble and .gitignore

I've been looking at the .gitignore files in various racket packages, and the ones I've seen don't ignore files generated by scribble (.html .css, etc.). So what is the common practice for keeping those files out of source control? Racket Users list: http://lists.racket-lan
