Bug: Nixos not rebuilding after regreet was added to stylix

[psynyde]

I'm creating this issue for who are facing this error below or something similar even though their system doesn't use regreet at.

       error: The option `programs.regreet.cursorTheme' does not exist. Definition values:
       - In `/nix/store/k5zm4zdrgbn0483a4pxgz1pb49a266hm-modules/regreet/nixos.nix':
           {
             _type = "if";
             condition = false;
             content = {
               name = "macOS-BigSur-White";

changing stylix input to github:danth/stylix/cf8b6e2d4e8aca8ef14b839a906ab5eb98b08561. should fix the issue.

I assume the main issue is nixpkgs-unstable introduced more customization to regreet which isn't available on stable (ie. 24.05) The input above points to the commit before regreet was introduced in styix.

I assume the main issue is nixpkgs-unstable introduced more customization to regreet which isn't available on stable.

Do you mean by "stable", the nixos-*.* (like nixos-24.05) Nixpkgs branches? IIRC, regular feature additions are not backported from nixos-unstable to these branches. In other words, this option is intentionally lacking.

Either way, thanks for posting this for reference.

In the future, https://github.com/danth/stylix/issues/543 would partially resolve similar issues.

I will close this issue, as I don't think there is much Stylix can do about this at this point. Feel free to re-open, if I am wrong on this.

Setting stylix.targets.regreet.enable to false doesn't help on NixOS 24.05. Does this mean there's no way to update Stylix past cf8b6e2d4e8aca8ef14b839a906ab5eb98b08561 until switching to 24.11 or unstable?

I see your use case. Maybe we could backport to release-24.5 a check whether the regreet package exists. @danth, what do you think?

Basically, can't update stylix, past the update that added regreet, because stylix is set to expect regreet to have options that are only available in nixpkg-unstable.

So the options don't exist so stylix fails the build.

It's not relevant if you have regreet enabled or not, and it's not relevant if you have regreet installed or not.

Right now stylix 24.05 doesn't work.

If you check programs.regreet in search.nixos.org/options and compare what options are available in 24.05 and unstable, there are more options in unstable. Hopefully these options can be removed from stylix 24.05.

Thank you!

I already mentioned this:

What do you mean by "stylix 24.05"?

If you mean the release-24.05 Stylix branch, then this should not be an issue because it does not have a regreet module. If you mean that you are explicitly overriding Stylix's github:NixOS/nixpkgs/nixpkgs-unstable input with github:NixOS/nixpkgs/nixos-24.05 (which is clearly behind the Nixpkgs version Stylix master supports), then there is obviously a version mismatch possibility beyond Stylix's control. Note that Stylix deliberately updates (unless we forget to do so) its flake.lock versions when using features that are not already available in the current flake.lock versions.

Similar to Nixpkgs and Home Manager, Stylix supports only the latest versions from flake.lock, unless logically necessary. For example, Nixpkgs provides simultaneously several nodejs versions.

@trueNAHO Thanks for answering. with

inputs = {
  nixpkgs.url = "github:NixOS/nixpkgs/nixos-24.05";
  stylix = {
    url = "github:danth/stylix";
    inputs.nixpkgs.follows = "nixpkgs";
  };
};

Which I assume means I get stylix/release-24.05? (please advice) But when I do a nix flake update I get this issue, where stylix expects regreet options from nixos-unstable

nixpkgs 24.05:

        programs.regreet.settings
        programs.regreet.package
        programs.regreet.enable
        programs.regreet.extraCss
        programs.regreet.cageArgs

nixpkgs unstable:

        programs.regreet.settings
        programs.regreet.package
        programs.regreet.enable
        programs.regreet.theme.name
        programs.regreet.font.size
        programs.regreet.font.name
        programs.regreet.iconTheme.name
        programs.regreet.cursorTheme.name
        programs.regreet.theme.package
        programs.regreet.iconTheme.package
        programs.regreet.font.package
        programs.regreet.extraCss
        programs.regreet.cursorTheme.package
        programs.regreet.cageArgs

@sigboe unsure if you are having this problem, but no you are pulling the master branch for Stylix. You would need to adjust stylix.url to be github:danth/stylix/release-24.05

[dmarcoux]

I encountered this issue today after updating my flake.lock file. I have the following inputs:

inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/nixos-24.05";

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

    stylix = {
      url = "github:danth/stylix";
      inputs.nixpkgs.follows = "nixpkgs-unstable";
    };
};

I use nixpkgs for most of my configuration, but sometimes I rely on nixpkgs-unstable for a specific software/app. This should work, right?

[LovingMelody]

That will only make the flake use packages from unstable but not the nixosModules. You would need to define your system with unstable instead of stable or as previously stated use the stable branch of stylix that matches your nixpkgs.

I'm running into this now and I'm a little unclear about what I should expect from the main branch. I totally understand having the release-24.05 branch (and its inputs) be set to specific revisions, and I totally understand that things will break if a user overrides the nixpkgs input with a follows.

Should I expect main to work though? I'm hitting this error on main without overriding the nixpkgs input.

Ideally, yes.

Does commit 7689e621f87bce7b6ab1925dfd70ad1f4c80f334 resolve the issue?
