@srxl nice! A few years ago (prior to gleam v1.0) I created nix-gleam. Initially I was gonna make a gleam2nix kind of application but found out that I can just read the gleam.toml and manifest.toml and dynamically pull the dependencies that way. Is there a requirement for a nix code generator now?

I don't really write any gleam anymore so it's probably good if someone else is creating a well maintained project for this :) but AFAIK my builder still works.

@arnar i did see that one, it's pretty nice! informed a good chunk of my earlier experimentations before i discovered the gleam compile-package command.

my goal with gleam2nix is to eventually have something that can be upstreamed to nixpkgs. IFD isn't allowed in there, so I can't rely on the same importTOMLtechniques that nix-gleam does - going for the classic "*2nix"-style nix codegen was the most obvious way to implement it in an IFD-free way, to my knowledge.

it's definitely a lot more convenient though - at some point, i might add an option to generate the gleam.nix file in a derivation, kinda like what crate2nix can do (assuming that's allowed upstream. i think it is, because iirc the elixir tooling can do a similar thing).

@srxl I see. That makes sense! Best of luck with that! :)
