Re: [racket-users] How to call a macro on each element of a list

I found a solution to my problem. I realised that it was better to use a function instead of a macro to generate the code. I created a list and appended the different parts of the code I wanted to generate in bottom up manner. eval-ing the list can run the code. If that works for you, good.

Re: [racket-users] IO in racket is painful

Isn't it true that the scanf format string is just a poor man's regular expression pattern (i.e. just character classes) that however also allows you to specify how to convert matches? It may be a succinct notation, but it is also misleading (for example, a single space in the format string

[racket-users] Racket internal error when trying to create an executable

Hi, I'm getting an error when trying to create an executable for a program that uses the math/statistics module. The simplest example that reproduces the issue is: #lang racket (require math/statistics) (let* ([s empty-statistics] [s (update-statistics s 1)] [s

[racket-users] FFI | Unions

Hello everyone, I am trying to use a set of bindings to SDL2 and I am at loss on how to use C unions. If I understood correctly both make-union-type and _union procedures create a new ctype; but how do you actually create instances of these unions? Thank you for your attention. -- You

Re: [racket-users] using a different "scribble.tex"

Oops, guess I forgot to update this thread. This commit ( https://github.com/racket/scribble/commit/2881ef290ddfef6b645eaabc997c9bd6fddaa641) tries to address this problem. Roughly, you can use `latex-defaults+replacements` to replace `scribble-load-replace.tex` and override the macros that

Re: [racket-users] serialization of math/array

Thanks, but this does not solve the problem. I would need a solution which also works more generally, e.g., for arrays nested in structs etc.. As far as I understand, the canonical way to extend serialize is to add the prop:serializable property to the struct representing an array. But that

Re: [racket-users] using a different "scribble.tex"

Commenting out scribble.tex with an open comment in prefix.tex and closing comment in scribble.tex works, to a point. It hides scribble.tex, but it also hides any dynamic inclusions such as figure.tex. I have been trying to use the longtable package in preference to the stabular-based package
