feature(nix): Start LSP with steam-run on NixOS

[pqn]

We can't unconditionally run this on all operating systems. Is there a simple way to detect NixOS?

[qverkk]

Oh sorry ! this was meant just for me to make a patch file and apply it on NixOS, this can be closed :D maybe if other NixOS users will want to set codeium, they can use this PR as a patch entrypoint

[pqn]

Sounds good, I will close this. Feel free to leave a note in issues, discussions, wiki, etc. to point to this for future users.

@qverkk I'm curious as to why steam-run will work, hitting this same isssue but having steam for this seems... wrong

The binaries are downloaded automatically by codeium, which is why it's hard to make a patch or a general deriveiation for nix to add it to your path. One way of doing it manually is by running

patchelf \
      --set-interpreter "$(cat $NIX_CC/nix-support/dynamic-linker)" \
language_server_linux_x64

to make the file executable. I have chose to use steam-run as it was way easier. Also it's not directly linked to steam as u may think. Here is a more detailed answer: https://unix.stackexchange.com/a/522823

yeah after I asked I found the answer, I went ahead and made a derivation for the language server:

with import <nixpkgs> {};

stdenv.mkDerivation rec {
  name = "codeium";
  src = fetchurl {
    url =
      "https://github.com/Exafunction/codeium/releases/download/language-server-v1.2.28/language_server_linux_x64";
    sha256 = "sha256-jvRrTSevGEC+j/bdt6bfPEhk/t0jG5YT3P0MachWoSk=";
  };
  nativeBuildInputs = [ autoPatchelfHook ];
  unpackPhase = "true";
  installPhase = ''
    ls -lR $src
    mkdir -p $out/bin
    cp $src $out/bin/language_server_linux_x64
    chmod +x $out/bin/language_server_linux_x64
  '';
}

and then I use it in my home-manager:

  home = {
      file = {
        codeium_ls = {
          target = ".codeium/bin/02626b4ccb9ec6fa5d7ad27101ebb1480e2a80fb/language_server_linux_x64";
          source = "${codeium-ls}/bin/language_server_linux_x64";
        };
  }

        };
  }

Oh damn, great job ! Did u skip the pkgs.codeium package available in the 23.05 and unstable release altogether? Cause the following path migth change codeium/bin/02626b4ccb9ec6fa5d7ad27101ebb1480e2a80fb/language_server_linux_x64

[dedsm]

yeah I added my own codeium.vim, but I imagine the sha can be somewhat automated as well, if I end up using codeium I'll probably do it a bit better.

  codeium = pkgs.vimUtils.buildVimPluginFrom2Nix {
    name = "codeium-nvim";
    src = pkgs.fetchFromGitHub {
      owner = "Exafunction";
      repo = "codeium.vim";
      rev = "1.2.26";
      hash = "sha256-gc4BP4ufE6UPJanskhvoab0vTM3t5b2egPKaV1X5KW0=";
    };
  };

[qverkk]

Ah this is similiar to what nixpkgs currently has :D https://github.com/NixOS/nixpkgs/blob/a558f7ac29f50c4b937fb5c102f587678ae1c9fb/pkgs/applications/editors/vim/plugins/generated.nix#LL1964C7-L1964C7

Lmk if the unique id in .codium will ever change with ur approach :D u can add me on discord if u want: qverkk

[socherbyc]

For now, the easiest way to make it work is using an alias like this:

{
  programs.bash.shellAliases = {
    nvim = "steam-run nvim";
  };
}
