Nix: mode emoji is not found

[andys8]

I did install rofi-emoji with nix package manager in arch. When I run rofi -show emoji -modi emoji it'll tell me "mode emoji is not found".

nix-env -i rofi rofi-emoji

I'm I missing something? Is this reproducible for others?

In addition I noticed it will have the same behavior if I install it in arch (via yay -S rofi-emoji rofi), but maybe I'm mixing it up with nix.

rofi v1.6.1

I do not use Nix, and I'm also not the author of the Nix package.

Try to run rofi -plugin-path /path/to/rofi-emoji/plugin -modi emoji -show emoji and see if that works. Perhaps Rofi is not set up to load from the correct directory?

It could also be that the package is using a different Rofi version when compiling the plugin than the version you use when you try to run it and Rofi silently ignores plugins it cannot load. (Just a guess)

The actual solution due to nix's purity is to overwrite the rofi package with one that includes the rofi-emoji plugin. You can do nix-shell -p '(rofi.override { plugins = [ rofi-emoji ]; })' to install it temporarily.

If you want to install stuff permanently you should override the package in ~/.config/nixpkgs/config.nix and then install it with nix-env. I've never used nix without nixos so I'm not sure how to do that, sorry.

On nixos to install rofi-emoji you need to add environment.systemPackages = [ pkgs.rofi.override { plugins = [ pkgs.rofi-emoji ]; }; ]; to your /etc/nixos/configuration.nix

Feel free to ask me if you have any other questions, or want me to explain in more detail. I'm by no means a nix expert but I'd be glad to help if I can

Thanks a lot!

I'll close this issue as its not a problem with the codebase, but feel free to keep using this issue to troubleshoot problems with the Nix package.

@JustABanana That's awesome. Thanks for the help :)

@MaeIsBad any thoughts?

You might have already fixed this, but I wanted to share a solution with other as I also stumpled across this problem. Replace rofi in your system packages with (rofi.override { plugins = [ rofi-emoji ]; }) (enclosed in parentheses). My system packages now look like this:

environment.systemPackages = with pkgs; [
  # ...
  # rofi <-- Do not include this as well!
  (rofi.override { plugins = [ rofi-emoji ]; })
  # ...
];

Hope this helps!

:point_up: This is how I have it in my Nix config, too.

(Yeah, I've switched to Nix since after this issue was closed.)
