$VIMRUNTIME not set on NixOS about nixvim

[volkswagenfeature]

A workaround I'm using at the moment is just to make a symlink where it expects to see the folder:

sudo ln -s /nix/store/7vaavg9j2q0xg6w1wr42hir1vbsh2b90-neovim-0.7.0/share/nvim/runtime /etc/nvim

I'm sure there's a more sensible way to get the hash in the nix store path, but since I'm new to Nix I've just been using file $(which nvim) to find out where it's located.

I'll take a look at this, but now that 21.11 is released (and AFAICT it works there), maybe it's not worth patching in the support for older versions. If there's enough demand I'll add something for this though.

[volkswagenfeature]

Yeah, mostly opened for continuing tracking on the $VIMRUNTIME issue that's been following us... I actually suspect it's still present in 21.11 some situations. I've had it crop up since upgrading, but I haven't yet taken the time to make it reproducible, so it might be my imagination.

[JulienMalka]

I can confirm that I've also been having this issue on NixOS 22.11

[Church-]

Same here, also having this issue.

[pta2002]

Ah damn it, thought it had gone away! Can you share a basic config @JulienMalka and @Church-? Also, what module are you using to set up nixvim?

[Church-]

Hey there, I'm using the nixOS module to set up my config, and my config is

{ pkgs, config, ... }:

{
  programs = {
    nixvim = {
      enable = true;
      viAlias = true;
      vimAlias = true;
      options = {
        termguicolors = true;
        background = "dark";
        ignorecase = true;
        swapfile = false;
        showmatch = true;
        hlsearch = true;
        wildmode = [ "longest" "list" ];
        expandtab = true;
        tabstop = 4;
        shiftwidth = 4;
      };
      extraConfigVim = ''
        set completeopt=menuone,noinsert,noselect              
        set shortmess+=c                                       
        set whichwrap+=<,>,h,l,[,]                             
        au BufRead,BufNewFile *.md setlocal textwidth=80

        au BufWrite *.rs :Autoformat
        au BufWrite *.nix :Autoformat
      '';
      plugins = {
        lsp = {
          enable = true;
          servers = {
            rnix-lsp = { enable = true; };
            rust-analyzer = { enable = true; };
          };
        };
      };
    };
  };
}

Changed name to reflect that this is no longer a 22.05 issue. I also had the same thing pop up on 22.11 on my WSL install: see configuration

[k4lipso]

can confirm the same issue with nixpkgs/nixos-unstable. creating the symlink as mentioned by @volkswagenfeature worked for me.
still i have to point nvim to the correct config using nvim -u /etc/nvim/sysinit.lua

[alexjp]

In my case, the runtime issue was fixed with commenting this line: https://github.com/pta2002/nixvim/blob/main/wrappers/nixos.nix#L35

[lumpsoid]

same here
but non of the tricks here works for me

it is strange that, but I am not so experienced with NixOS, when I added nixvim, the log sayed that ... input 'nixvim/pre-commit-hooks/nixpkgs-stable' but the documentation stated that nixvim needs an unstable version

NixOS with flakes

{
    description = "lump";

    inputs = {
        nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
        home-manager.url = "github:nix-community/home-manager";
        home-manager.inputs.nixpkgs.follows = "nixpkgs";
	nixvim.url = github:pta2002/nixvim;
	nixvim.inputs.nixpkgs.follows = "nixpkgs";
    };

    outputs = inputs@{ nixpkgs, home-manager, nixvim, ... }: {
        nixosConfigurations = {
            qq = nixpkgs.lib.nixosSystem {
                system = "x86_64-linux";
                modules = [ 
                    ./configuration.nix 
                    home-manager.nixosModules.home-manager {
                        home-manager.useGlobalPkgs = true;
                        home-manager.useUserPackages = true;
                        home-manager.users.qq = import ./home.nix;
                    }
		    nixvim.nixosModules.nixvim {
		        programs.nixvim = {
		        	enable = true;
		        	options = {
		        		number = true;
		        		relativenumber = true;
		        		shiftwidth = 4;
		        		tabstop = 4;
		        	};
		        	plugins.oil.enable = true;
		        	plugins.lightline.enable = true;
		        	maps = {
		        		normal."-" = {
		        			action = "<cmd>require('oil').open";
		        		};
		        	};
		        };
		    }
                ];
            };
        };
    };
}

and I also have problem with infinite loop if I trying to call nixvim from ./home.nix

In my case, the runtime issue was fixed with commenting this line: https://github.com/pta2002/nixvim/blob/main/wrappers/nixos.nix#L35

Setting wrapRc = true; fixed this issue for me on nixos-unstable. My config worked just fine on nix-darwin and I noticed the darwin wrapper has wrapRc forced to true, so I guess I need true for both

[teto]

wrapRc sets VIM which is used as VIMRUNTIME see :h VIMRUNTIME
