wgsl-analyzer is not in NixOS stable

[harmanhobbit]

It seems that about 2 weeks ago wgsl was added to the supported lsp languages. It uses pkgs.wgsl-analyzer as it's default package. Unfortunately this package is only available in the unstable channel meaning nvf can't be used if your main channel is stable.

I do have unstable as an extra input on my flake but for the life of me cannot work out how to pass the unstable package through to nvf. I am also unsure why I am having to declare a package for lsp support for a language that I have not enabled.

I am fully aware that this might just be a quirk of the way my system is configured so wanted to start a discussion to see if I could get any help before opening an issue.

Thanks

nvf follows nixos-unstable by default. Removing a possible inputs.nixpkgs.follows line would automatically have your nvf use the same nixpkgs channel as this repository. Though if you have an input for unstable, then set inputs.nixpkgs.follows under inputs.nvf to the name of your unstable input. For example:

# flake.nix
 inputs = {
     unstable.url = "github:NixOS/nixpkgs/nixos-unstable";
     nvf = {
       url = "github:NotAShelf/nvf";
       inputs.nixpkgs.follows = "unstable";
     };
 };

I am also unsure why I am having to declare a package for lsp support for a language that I have not enabled.

This is a "quirk" of Nix. Even though the package will not be realized (i.e. it won't be fetched into your store) Nix evaluates, or rather, tries to evaluate it to e.g., calculate hashes.

This worked perfectly. Thanks!
