[racket-users] How to document modules that reprovide other modules?

If I have two modules `foo` and `foo/extra-thing`, and `foo` requires and re-provides all the exports of `foo/extra-thing`, how do I correctly document that fact with `defmodule` and `declare-exporting`? The documentation for those two scribble forms doesn't include examples, the grammars for

[racket-users] encountered old PLT Scheme GUI that still works great

Just an interesting thing. I restarted work back at a place that I left several years back where we still use a custom IDE written in PLT Scheme 4.25, just before it became Racket. It's about 25K lines of GUI. Out of curiosity, I recompiled everything today on 7.2.0.6 Chez racket. I ran

Re: [racket-users] Scribble: is there a way to inject content from another file without creating a section?

A `#lang scribble/base` module just defines and provides `doc` as an instance of `part`, and `include-section` imports and returns that `doc`. That is, @include-section["x.scrbl"] is equivalent to @(require (rename-in "x.scrbl" [doc x:doc])) @x:doc You could instead extract the part's flow

[racket-users] Scribble: is there a way to inject content from another file without creating a section?

Scribble's include-section is great for splitting the document source into multiple files. I'm looking for a way to inject content from another file without making a numbered section. The motivation for this is to create problem sets for my math classes in a way that I could keep each question

[racket-users] json, performance, racket cs, puzzlement, etc.

After the recent discussion on json parsing performance, I spent some time doing a quick port of enough of attoparsec and aeson (haskell libraries providing, respectively, byte-oriented parser combinators and json parsing) to do some testing. The result: really slow. (This is where the puzzlement

[racket-users] Is one path a direct or indirect subdirectory of another path?

What is a portable, correct, efficient way to check whether one path is "under" -- a direct or indirect subdir of -- another path? AFAICT there's no racket/path function for this. Over the years I've done various ad hoc things that seem non-ideal. Including: 1. Use path->string and regexp. 2. Use
