at first I thought it was because I had both the home-manager module and overlay enabled but that is not the case

[kirilsh1993]

@DockterTeagle Happened to me as well, managed to get it to build by adding 'programs.hyprpanel.overlay.enable = true' to my config.
Not sure why it's failing, suspect a conflict with Firefox extensions via NUR.

note: used to build without this line, one of the recent merges caused it to start failing.

Hmmm that is pretty weird. Can you try my fork out to see if it resolves it?

{
  inputs = {
    hyprpanel.url = "github:benvonh/HyprPanel";
  };

  # ...
}

BTW, in case this info was missed, you do need to set overlay.enable unless you do it manually yourself; which you have to when using HM as a NixOS module and you set useGlobalPkgs.

[DockterTeagle]

inputs.hyprpanel.url = "github:Jas-SinghFSU/HyprPanel";
...
modules = [
               inputs.hyprpanel.homeManagerModules.hyprpanel

];

does this not set the overlay? if not then yeah I did add overlay.enable = true and it fixed it

[benvonh]

Lol no, it doesn't by default because of that case. But there should have been a custom error message that I put in telling you this information :(
