rnix-lsp VS nickel-nix

There's a work in progress language server: rnix which I'm using in emacs. Features like autocomplete are limited though, I'm guessing because you'd need to evaluate the actual Nix code to correctly deduce what properties exist.

There’s rnix-lsp.

https://github.com/nix-community/rnix-lsp works ok, it has some autocomplete but it does not infer options most packages expose unfortunately.

Looks cool! Any thoughts on the relationship between Statix and https://github.com/nix-community/rnix-lsp ?

Have you tried https://github.com/nickel-lang/nickel-nix ?

I didn't use it yet, but looks like this supposed to do it.

These days those aren't the only options; you can also use Nickel: https://github.com/nickel-lang/nickel-nix

Which isn't fully baked, no, but here's hoping.

One target-use case of Nickel is to be used as an alternative front-end for Nix (instead of Nix expressions). There is a draft RFC and a repository to use Nickel to write development shell (Nixel). The goal is that, one day, you can actually just transparently call to Nix code and into Nixpkgs. Until then, I totally understand that nothing can be the power of levering Nixpkgs... so your approach makes sense :)

Undecided; see https://github.com/nickel-lang/nickel-nix for a proof-of-concept of an integration that requires making no changes to either Nickel or Nix.
