Here is my flake: GitHub - refaelsh/dotfiles at 8a72f4fd458b83d1b4b02cb18d4c1fc20735f65c. I am building my NixOS from it.
Recently, I’ve added this: dotfiles/flake.nix at 8a72f4fd458b83d1b4b02cb18d4c1fc20735f65c · refaelsh/dotfiles · GitHub.
Its a flake I am working on my local hard drive - its supposed to configure Xmobar via home-manager module.
But I am getting this error when rebuilding my system:
error: infinite recursion encountered
Please help 
You don’t need an additional flake input for it, it’s already present in your flake.
You should be able to add (${inputs.self} + /nixmobar) or a relative path ../nixmobar (which is my personal preference) to your imports in your HM config.
Then you can delete the inner flake.nix.
I am sorry @waffle8946, but can I please bother you with concrete changes you are suggesting?
I am afraid I did not understand your answer at all.
I think @waffle8946 means something like this:
{
description = "NixOS flake";
inputs = {
# with the short url syntax, you don't need "?ref="
nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
...
# Delete this
# nixmobar.url = "./nixmobar";
};
outputs = {
...
};
}
and in home-manager/home.nix
{ ... }:
{
# programs.home-manager.enable = true;
home.stateVersion = "24.05";
# home.username = "refaelsh";
# home.homeDirectory = "/home/refaelsh";
imports = [
# Delete this
#inputs.nixmobar.homeModules.nixmobar
# Just import it like your other modules
../nixmobar # uses default.nix
./alacritty.nix
./git.nix
./fzf.nix
./lf.nix
./librewolf.nix
./kitty.nix
./mangohud.nix
./nixmobar.nix
./starship.nix
./termonad.nix
./wezterm.nix
# ./xmobar.nix
./zsh.nix
];
}
and then delete the flake.nix and flake.lock file in nixmobar/
@railwhale Thats exactly what I did a few days a go while I was developing my module and testing it and etc. Now, I wanna “package” my module as a flake. Thats why I have nixmobar.url = "./nixmobar";, it is intentional.
No, you want to expose the module as a flake output.
Just add a new entry in your top-level flake.nix in the outputs:
nixosModules.nixmobar = ./nixmobar;
No, you want to expose the module as a flake output .
Yes, you are correct. New terminology, still learning flakes
Just add a new entry in your top-level
flake.nixin theoutputs:
nixosModules.nixmobar = ./nixmobar;
But I wanna use the output of my new flake Nixmobar.
The way you are suggesting, I will not use the output of my new flake Nixmobar.
If you create a new flake output then you can use inputs.self.nixosModules.nixmobar
Or if it’s an HM module then you can name is homeModules/homeManagerModules.nixmobar (there’s no official naming per the schema for HM).
Thats exactly what I am currently doing. I have this in Nixmpobar’s flake output:
homeModules.nixmobar = import ./default.nix;
And then, I use it like this in my NixOS flake:
inputs =
{
.
.
.
nixmobar.url = "./nixmobar";
.
.
.
}
outputs =
{
.
.
.
modules = [
inputs.nixmobar.homeModules.nixmobar
];
.
.
.
}
But I get the error: infinite recursion encountered error.
That’s not what I wrote, I said keep it in one flake not two separate ones.
And use inputs.self.homeModules.nixmobar not a separate flake input.
Also you still haven’t shared the full error, just saying there’s infrec doesn’t tell us much.
But I suggest following my recommendation first, then check if there’s an error, so that we are not chasing an issue that may not need addressing.
That’s not what I wrote, I said keep it in one flake not two separate ones.
Oh! Sorry, I did not understood you. Now I get what you meant. I think. Let me think on it and I get back here asap.
@waffle8946 I did what you are suggesting and now I this error: error: The option home does not exist.
Here are the dotfiles: GitHub - refaelsh/dotfiles at 2bce698c5f28aefa0270fc26d0581d5ddd7fd3d7.
What I did in short is like this (in my NixOS flake):
outputs =
{ self, nixpkgs, ... }@inputs:
{
homeModules.nixmobar = import ./nixmobar/default.nix;
nixosConfigurations = {
myNixos = nixpkgs.lib.nixosSystem {
specialArgs = {
inherit inputs system;
};
modules = [
./nixos/configuration.nix
inputs.home-manager.nixosModules.home-manager
./home-manager
inputs.self.homeModules.nixmobar
];
};
};
};
This line needs to go in your HM config, not your nixos config.
You are correct. I moved it there, and now I get this error:

That indicates that you’re trying to use a module arg that was never passed into the module system.
I’m guessing you didn’t add inputs to extraSpecialArgs as well?
But --show-trace should indicate which arg and the location it’s used.
Here is a run with --show-trace:
