Somehow (I wish I remembered how so I can report it) I ended on the page https://lists.racket-lang.org/listinfo/ It lists three Racket mailing lists, and all the links are dead, in the sense tha following them leads to a report "Bug in Mailman version 2.1.15" Perhaps that page should be changed

I found in the documentation runs but does nothing visible. I was hoping to use Racket in Ludum Dare in about 10 days. Maybe I'll have to restrict myself to 2D. Or a text-only game. Haven't done one of those yet. -- hendrik > > s. > > On Tue, Sep 24, 2019 at 12:05 PM H

[racket-users] syntax-parse and iterecursion

I've read the syntax-parse and its documentation, and I'd like to know if there's a way for a macro to accept a varying number of parameters without them having to be handled in a uniform way, spliced into a list. I'd like to be able to expand (foo a1 a2 a3 a4 a5) into something like (bar a1 (

Depth-first searches are easy to code by simple recursion. Breadth-first searches are good for finding short solutions and not getting caught in infinite recursions. Are there any ready-made tools in Racket for turning depth-first search code into breadth-first by strategic use of continuatio

[racket-users] transparency in Pict

I'm wondering how to cut a transparent hole in something. Say I have a rectangle and I want to make part of it transparent so that I cn see what's behind it. Drawing a transparent rectangle on top of it won't workm because it'll just reveal the original rectangle. The only way I cn see it to dr

[racket-users] minor infelicities in style guide

Section 1.1 mentions PLT. Is this obsolete? It is at least confusing or someone who does not know Racket history. Section 2.2 Always Test It should mention that when you formulate a test you should test the test *before* you modify the code. At present the warning about an inadequate test
