csharp-ls error

[henrybley]

Hi, I am new to nix and vim and trying to use nixvim but I am getting this error when trying to rebuild.

`error: attribute 'csharp-ls' missing

   at /nix/store/9iswkvfj5yrnjc0np1xvgxmyw3bsfsss-source/plugins/lsp/language-servers/default.nix:45:17:

       44|       description = "Enable csharp-ls, for C#.";
       45|       package = pkgs.csharp-ls;
         |                 ^
       46|       serverName = "csharp_ls";`

You need to have a quite up to date nixpkgs-unstable

[henrybley]

thanks, that solved it for me

So people have to use the unstable branch until csharp-ls is available in stable (like 23.11)?

I'm pretty sure you're supposed to match your nixvim and nixpkgs branches. If you're on nixos-unstable/nixpkgs-unstable you use the main branch. If you're on nixos-23.05 you use the nixvim/nixos-23.05 branch.

[traxys]

Exactly, tough there still could be some breakage as we were not as carefull as could be before the split. But we only test nixvim with the unstable input of the flake, and it is never older than 1 week.

Thanks for the reply! And it seems like I got it somehow :) I am still new to nix, so I'm learning along.
I will put here what I did to make it work, if someone else got the same question:

{ pkgs, lib, ... }:
let
  nixvim = import (builtins.fetchGit {
    url = "https://github.com/nix-community/nixvim";
    ref = "nixos-23.05"; # Change this with newer versions
  });
in
{
  imports = [ nixvim.homeManagerModules.nixvim ];
  ...
}
