Re: [racket] question on pluggable modules

I tend to define such constants in a file dubbed 'basics' and require it everywhere. See https://github.com/mfelleisen/Acquire for example. There 'basics' contains the constants I need for most of the game implementation and some simple functions too. -- Matthias On Nov 3, 2013, at 1

[racket] What #lang to use to create teachpack?

I'm trying to create a teachpack for use with Intermediate Student Language. I believe that I need to create a source file that uses the (provide ...) form and I need to put it into a package. I have two questions: - What, if anything, can I put into the info.rkt file to get my teachpack on

[racket] question on pluggable modules

Program P uses several functions (say, f and g) which can be implemented in several different ways (think of (f,g) as a Java interface, with (f1,g1) as one implementing class, (f2,g2) as another implementing class, etc.) I'd like to be able to run the program with one implementation, then with

I've change Scribble to hyperlink section references by default in LaTeX/PDF output. The change turned out to be easy, due to improvements back in July that deliver a LaTeX-level label to macros that render section links (when the referenced section is within the same document). At Wed, 23 Oct 20

Re: [racket] realm of racket

Please work your way thru HtDP/2e first. Realm assumes people have seen a full course on programming (2e is almost complete) and have the maturity to work through some typical first problems. When you're done Realm will be just fine for you. -- Matthias On Nov 3, 2013, at 6:19 AM, Saad Bas

But I have another question. What should I do if need to go back to BSL from time to time as I am still working with Htdp/2. Will you advise to go through Realm of Racket fully and then re-try Htdp/2? Saad On Sun, Nov 3, 2013 at 2:14 PM, Geoffrey S. Knauth wrote: > Glad you got it working!

Re: [racket] realm of racket

Saad, at first I thought the problem was you put a space after the single-quote mark. I tried what you entered using the Beginning Student with List Abbreviations language, and it worked, space or no space: > '((1 3 5 7 9) (2 4 6 8 0)) (list (list 1 3 5 7 9) (list 2 4 6 8 0)) > ' ((1 3 5 7

[racket] realm of racket

I have been working with Htdp/2 as an absolute beginner and finding it difficult have switched to Realm of Racket. In the first pages it asks one to download Racket which I already have but in the BSL mode. When using it I type in the following in the interactions panel as advised by Realm of Rac
