How to use packaged fish plugins in home-manager

Help
1

Hello everyone,

I am trying to understand how to add a fish plugin to my fish shell in my home-manager configuration and activate it. In the nixos-wiki-fish I could find how to use fish plugins from github like this:

 programs.fish.enable = true;
 programs.fish.plugins = [
   {
     name = "z";
     src = pkgs.fetchFromGitHub {
       owner = "jethrokuan";
       repo = "z";
       rev = "e0e1b9dfdba362f8ab1ae8c1afc7ccf62b89f7eb";
       sha256 = "0dbnir6jbwjpjalz14snzd3cgdysgcs3raznsijd6savad3qhijc";
     };
   }
   { name = "grc"; src = pkgs.fishPlugins.grc.src; }
  ];

however, I don’t know how to add an already packaged fishPlugin to my home-manager configuration. When I try the following configuration:

programs.fish = {
  enable = true;
  plugins = with pkgs.fishPlugins; [ tide ];
};

I get the error:

error: undefined variable 'tide'

       at /home/user/.config/nixpkgs/home.nix:113:40:

          112|     };
          113|     plugins = with pkgs.fishPlugins; [ tide ];
             |                                        ^
          114|   };

       … while evaluating the attribute 'value'

and when I try:


programs.fish = {
  enable = true;
  plugins = [ { name = "tide"; src = pkgs.fishPlugins.tide.src; } ];
};

I get the error:

error: attribute 'tide' missing

       at /home/user/.config/nixpkgs/home.nix:114:30:

          113|     plugins = [
          114|       { name = "tide"; src = pkgs.fishPlugins.tide.src; }
             |                              ^
          115|       # { name = "colored-man-pages"; src = pkgs.fishPlugins.colored-man-pages.src; }

       … while evaluating the attribute 'fishPlugins.tide.src'

I am new to nix and I don’t know how I can do this correctly. Can anyone help me to troubleshoot this or tell me how I am doing this wrong? I also read something about wrapFish in nixpkgs-fish, but I don’t really know how to use it. Any help is greatly appreciated!

What channel are you using to build your configuration?

That plugins seems only to exist in unstable and 22.11.

Thanks for the quick reply. I was on home-manager 22.05. I changed it to unstable:

~/.config/nixpkgs~> nix-channel --list

home-manager https://github.com/nix-community/home-manager/archive/master.tar.gz

When I now do home-manager switch with this config:

{ config, pkgs, ... }:

{
  home.username = "user";
  home.homeDirectory = "/home/user";

  home.packages = with pkgs; [
    exa
  ];

  programs.fish.enable = true;
 
  nixpkgs.config.allowUnfree = true;

  home.stateVersion = "22.05";
  programs.home-manager.enable = true;
}

, I get another error :

~/.config/nixpkgs~> home-manager switch                                               2650ms  Fr 13 Jan 2023 11:35:10 CET
error: attribute 'numbers' missing

       at /home/tipi/.nix-defexpr/channels/home-manager/modules/services/picom.nix:144:14:

          143|     activeOpacity = mkOption {
          144|       type = types.numbers.between 0 1;
             |              ^
          145|       default = 1.0;
(use '--show-trace' to show detailed location information)

any idea why? I don’t even have picom in my config …

(Btw: I am using nix on Fedora 37, if it is relevant at all)

You have not updated your nixpkgs to unstable, but only the home-manager channel.

From what we can see in your channel list, you are inheritting nixpkgs from the systems nixos channel.

Yes you were right. The Issue was with the channels. Thank you very much for your help!
