Additional information

I try to install hyprland plugins in HM, the instruction is:

wayland.windowManager.hyprland.plugins = [
inputs.hyprland-plugins.packages.${pkgs.system}.hyprbars
];
I get the
error : attribute 'inputs' missing.

But I have passed the inputs to HM:

modules = [
./hosts/surface

      nixos-hardware.nixosModules.microsoft-surface-pro-intel

      home-manager.nixosModules.home-manager {

        home-manager.useGlobalPkgs = true;
        home-manager.useUserPackages = true;
        home-manager.extraSpecialArgs = inputs;
    
        home-manager.users.ventus = import ./home;
      }
    ];

it doesn't work.
and then I tried to add these inputs manualy:

{pkgs, inputs, lib, hyprland-plugins, hyprgrass, ...}:

then it is the new error:

Hey, I had this same issue as you where I tried to pass inputs to extraSpecialArgs. This comment helped though: nix-community/home-manager#1698 (comment)

Basically, instead of passing inputs broadly, just inherit the specific inputs you would like:

{
	inputs = {
		apple-fonts = { #... };
	};
	outputs = {self, nixpkgs, home-manager, apple-fonts, ...} @ inputs: nixosConfigurations = {
		user = nixpkgs.lib.nixosSystem {
			modules = [
				home-manager.nixosModules.home-manager {
					home-manager.extraSpecialArgs = {inherit apple-fonts;};
				}
			];
		};
	};
}

Sorry, this seems to be a skill issue, not an issue with nixpkgs or home-manager. In short, specialArgs in inputs.nixpkgs.lib.nixosSystem defines which arguments you want to pass to each separated modules. You may need something like

{
	inputs = {
		nixpkgs.url = "...";
		home-manager.url = "...";
	};

	outputs = inputs: {
		nixosConfigurations = {
			nixos-machine = inputs.nixpkgs.lib.nixosSystem {
				system = "x86_64-linux";
				# ...
				specialArgs = {
					inherit inputs;
				};
			};
		};
	};
}

So you can write

{ inputs, ... }:

{
	# ...
}

in modules.

It is worth noting that here or the nix repo issues are not very suitable places to ask questions. You can go to https://discourse.nixos.org or https://matrix.to/#/#users:nixos.org to get more help.
