Describe the bug

When following the updated install instruction for the "advanced config", I added the following to my nix config:

    nixpkgs.overlays = [
      (self: super: {
        inherit
          (self.lixPackageSets.stable)
          nixpkgs-review
          nix-direnv
          nix-eval-jobs
          nix-fast-build
          colmena
          ;
      })
    ];
    nix.package = pkgs.lixPackageSets.stable.lix;
      .....

When attempting to build this configuration, I was presented with:

error:

         at /nix/store/pxnx7dbr0pz3qpgw2r315wdbb00afdw7-source/lib/attrsets.nix:1544:13:

Command 'nix --extra-experimental-features 'nix-command flakes' build --print-out-paths './nixos#nixosConfigurations."hostname".config.system.build.toplevel' --no-link' returned non-zero exit status 1.

elsewhere in my config I have direnv enabled:

    programs.direnv = {
      enable = true;
      nix-direnv = {
        enable = true;
        package = pkgs.nix-direnv;
      };
    };

Removing this configuration resolved the issue.

I was also able to resolve the issue by removing the lix overlay for nix-direnv and adjusting my direnv config like so:

    programs.direnv = {
      enable = true;
      nix-direnv = {
        enable = true;
        package = pkgs.lixPackageSets.stable.nix-direnv;
      };
    };

However I am not sure if this is ideal.

Steps To Reproduce

1. Copy and paste excerpt from the advanced config install doco
2. have programs.direnv.enable = true;

Expected behavior

I would expect the overlay to be compatible with my existing configuration and to function without modification.

nix --version output

nix (Lix, like Nix) 2.91.3

Additional context

Add any other context about the problem here.

Does the issue persist if you remove only the package = pkgs.nix-direnv; line in your configuration?

Yes, It occurs even if the only direnv config is enable = true. I tried it with that line removed. Then I tried it with the entire nix-direnv section removed and it still had the issue.

Oh, it is a documentation error — it should be inherit (prev.lixPackageSets.stable) ….

I'll fix the docs, but that should fix your issue @eve-vxs

Hello! I can reproduce this issue. It happens in both my own system and a very minimal flake configuration. Changing it to prev.lixPackageSets.stable does not solve the issue.

Very minimal reproducer flake, built with nixos-rebuild build --flake .#example

{
  inputs.nixpkgs.url = "github:nixos/nixpkgs/nixpkgs-unstable";

  outputs =
    { self, nixpkgs }:
    {
      nixosConfigurations.example = nixpkgs.lib.nixosSystem {
        modules = [
          (
            { pkgs, ... }:
            {
              boot.loader.systemd-boot.enable = true;
              fileSystems."/" = {
                device = "/dev/sda1";
                fsType = "ext4";
              };
              networking.hostName = "example";
              nixpkgs.hostPlatform = "x86_64-linux";
              system.stateVersion = "25.05";
              nix.package = pkgs.lixPackageSets.latest.lix;
              nixpkgs.overlays = [
                (final: prev: {
                  inherit (prev.lixPackageSets.latest)
                    colmena
                    nix-direnv
                    nix-eval-jobs
                    nix-fast-build
                    nixpkgs-review
                    ;
                })
              ];
              environment.systemPackages = [
                pkgs.colmena
                pkgs.nix-direnv
                pkgs.nix-eval-jobs
                pkgs.nix-fast-build
                pkgs.nixpkgs-review
              ];
            }
          )
        ];
      };
    };
}

Interestingly, in the reproducer, commenting out all but one of the items in environment.SystemPackages fails for colmena, nix-direnv, nix-fast-build, and nixpkgs-review, but the build succeeds if only nix-eval-jobs is included. I'm not familiar enough with the internals to understand why.

I'm having the same issue, even after correcting my overlay as above. Everything builds fine if I overlay all the packages except nix-direnv (so nixpkgs-review, nix-eval-jobs, nix-fast-build and colmena are overlaid with those from prev.lixPackageSets.stable), but as soon as I add nix-direnv I get the same infinite recursion error.

For reference, my current direnv config is as follows:

programs.direnv = {
  enable = true;
  enableZshIntegration = true;
  nix-direnv.enable = true;
};

Perhaps, we are actually debugging another problem pertaining to nix-direnv only?

Possibly? I think the recursion is coming from nix-direnv already being overridden here, so when the lix overlay also overrides the same package (through pkgs.lixPackageSets.stable.nix-direnv) it gets caught up trying to apply the overrides on top of each other?

I'm not sure how this would be solved on either end, is it a case of giving the overrides a priority and applying them in sequence somehow? I haven't been able to find any similar instances online.

Possibly? I think the recursion is coming from `nix-direnv` already being overridden [here](https://github.com/NixOS/nixpkgs/blob/5a1cf2923635c75744eb9f1844eb91b1dd2931cc/nixos/modules/programs/direnv.nix#L74), so when the lix overlay also overrides the same package (through `pkgs.lixPackageSets.stable.nix-direnv`) it gets caught up trying to apply the overrides on top of each other? I'm not sure how this would be solved on either end, is it a case of giving the overrides a priority and applying them in sequence somehow? I haven't been able to find any similar instances online. <details> <summary>Full trace when trying to overlay `nix-direnv`</summary> ``` error: … while calling anonymous lambda at /nix/store/r33xw4w5nmpmfac4g47h1lmrcl4qlz7k-source/lib/attrsets.nix:1539:14: 1538| zipAttrsWith ( 1539| n: values: | ^ 1540| let … while calling the 'head' builtin at /nix/store/r33xw4w5nmpmfac4g47h1lmrcl4qlz7k-source/lib/attrsets.nix:1544:13: 1543| if length values == 1 || pred here (elemAt values 1) (head values) then 1544| head values | ^ 1545| else … while calling anonymous lambda at /nix/store/r33xw4w5nmpmfac4g47h1lmrcl4qlz7k-source/lib/attrsets.nix:1192:17: 1191| mapAttrs ( 1192| name: value: | ^ 1193| if isAttrs value && cond value then recurse (path ++ [ name ]) value else f (path ++ [ name ]) value … from call site at /nix/store/r33xw4w5nmpmfac4g47h1lmrcl4qlz7k-source/lib/attrsets.nix:1193:85: 1192| name: value: 1193| if isAttrs value && cond value then recurse (path ++ [ name ]) value else f (path ++ [ name ]) value | ^ 1194| ); … while calling anonymous lambda at /nix/store/r33xw4w5nmpmfac4g47h1lmrcl4qlz7k-source/lib/modules.nix:275:71: 274| # For definitions that have an associated option 275| declaredConfig = mapAttrsRecursiveCond (v: !isOption v) (_: v: v.value) options; | ^ 276| … while evaluating the attribute 'value' at /nix/store/r33xw4w5nmpmfac4g47h1lmrcl4qlz7k-source/lib/modules.nix:1118:7: 1117| // { 1118| value = addErrorContext "while evaluating the option `${showOption loc}':" value; | ^ 1119| inherit (res.defsFinal') highestPrio; … while calling the 'addErrorContext' builtin at /nix/store/r33xw4w5nmpmfac4g47h1lmrcl4qlz7k-source/lib/modules.nix:1118:15: 1117| // { 1118| value = addErrorContext "while evaluating the option `${showOption loc}':" value; | ^ 1119| inherit (res.defsFinal') highestPrio; … while evaluating the option `system.build.toplevel': … while evaluating the attribute 'mergedValue' at /nix/store/r33xw4w5nmpmfac4g47h1lmrcl4qlz7k-source/lib/modules.nix:1165:5: 1164| # Type-check the remaining definitions, and merge them.

The thing that's extra confusing is that I get the error even when providing a new value for package (which I would think would avoid the recursion by giving it a new value?

Also if Lix still lazy evaluates, when I removed the nix-direnv bit of config from programs.direnv, the package property shouldn't even evaluate because the property shouldn't even be read? or am I misunderstanding?

Also tried building with the latest version of the instructions from the page (which states to use final not prev as in this thread) and had the same issue.

Is the solution here maybe just to override programs.direnv as well?

Possibly? I think the recursion is coming from nix-direnv already being overridden here, so when the lix overlay also overrides the same package (through pkgs.lixPackageSets.stable.nix-direnv) it gets caught up trying to apply the overrides on top of each other?

I'm not sure how this would be solved on either end, is it a case of giving the overrides a priority and applying them in sequence somehow? I haven't been able to find any similar instances online.

Full trace when trying to overlay nix-direnv

That's correct.

The solution here is to remove nix-direnv from your overrides. As long as you do nix.package = pkgs.lixPackageSets.lix.stable;, nix-direnv will follow through as long as they keep this API.

It's quite uncommon/unexpected for a package to perform such things and this renders overlaying more complicated as you can see.

I will update the instructions to take into account this aspect, thank you all.
