[racket-users] Parenthesizing infix expressions in Redex renderings?

Hello all, I'm working on coding up a little language model in Redex, and I'd like to get it to render things in the form that my colleagues are used to. This means some infix operators as well as dealing with parenthesizing based on operator precedence. Here's a boiled-down sample of what I'm

Re: [racket-users] eq? of quoted expressions

Hello, eq? decides object identity, or pointer equality. Symbols are interned, which means that there's a table mapping symbol names to underlying objects, such that using the name twice results in the same allocated symbol object being returned. Pairs are not interned. Each time a new pair is

[racket-users] How to extend drracket:default-filters at editor startup?

Hello all, In order to add an entry to the file extension dropdown in DrRacket, a #lang's get-info procedure should respond to drracket:default-filters. This works - in the Pie integration for DrRacket, the corresponding entry is present. However, it is only present after the first Pie program

[racket-users] Experiences with Racket on RISC-V?

Hi all, I'm just wondering if anyone here has experience running Racket on Debian on RISC-V, either positive or negative. There is a Debian package, at least, but language implementations are often one of the more challenging things to make reliable on a new architecture. In case it matters, the
