I landed vector (and bytevector) literals in Steel. Next step, vector macro patterns and quasiquoting 🚀 github.com/mattwparas/steel/… #HelixEditor #lisp #scheme

implement vector literals by jrvidal · Pull Request #262 · mattwparas/steel

Implements vector and bytevector literals. TODO No vector patterns for macros. I'll probably work on it on a future PR.

I thought I knew some #scheme, but I just now realized that you can write code like this 🙃 #lisp
Some scheme code in a REPL: > (define . (x . (1 . ()))) > x => 1

I'm somewhat confused with `OsString` in Unix environments. Isn't it pretty much guaranteed that OS-level strings are basically nul-terminated? Why can we create them from an arbitrary buffer (with no nul checking)? cf. doc.rust-lang.org/1.77.2/std…

(Note that nul-termination _is_ checked when e.g. spawning a command, for its arguments and env variables)

Encuesta: ¿Hay interés por el tema del hardware? Estamos considerando buscar ponentes sobre RISC-V, diseño de hardware, sistemas embebidos, actividades de Maker Space, o traer partes de China para construir un POC. ¿Es esto de interés general, o es un tema de nicho?
