treewide: make stylix.image optional

[Flameopathic]

Closes: #200
Closes: #442

will make stylix.image optional, as long as stylix.base16Scheme is set

tasks

• alter most modules using config.stylix.image
• alter the option definition or set up a check to ensure that one of stylix.image or stylix.base16Scheme is set
• add option to each module
• alter the KDE module; would appreciate help from @danth who authored most of it, though if you don't have the time, i'm sure that i could figure it out eventually
• test

i wonder if, in some places, pixel.nix would be useful or better than setting nothing at all, though i'm not sure

• altered the KDE module; would appreciate help from danth who authored most of it, though if you don't have the time, i'm sure that i could figure it out eventually

This PR could be mostly generated with:

fd -e nix -X sed -i 's/config\.stylix\.image/lib.mkIf (\0 != null) \0'

• altered the option definition or set up a check to ensure that one of stylix.image or stylix.base16Scheme is set

I suggest adding an assertions where the config.stylix.image type is defined.

i wonder if, in some places, pixel.nix would be useful or better than setting nothing at all, though i'm not sure

Consistently wrapping with lib.mkIf (config.stylix.image != null) config.stylix.image might be the best solution.

For reference, #442 might contain more practical information.

i'll test it out doing just that, though it seems more complicated than the rest

good idea, done

sounds good and makes sense; why do anything more complicated

For reference, #442 might contain more practical information.

ah, hadn't noticed it. are you interested in me adding the proposed wallpaper option for every module that uses config.stylix.image?

Yes.

can't seem to get KDE themed, even with an image using the official release of stylix. is it known to be broken?

either way it may be best to, for the moment, disable KDE theming when there is no image, as #708 looks like it's about to change the module entirely

[Flameopathic]

set up individual toggles. failing to set stylix.image and intentionally enabling one of the wallpapers (stylix.targets.<name>.wallpaper = true) will cause an error; i'd like to fix that with an assertion, but I don't see a way to do that without setting up an assertion for every one individually.

i still need help with KDE for reasons explained previously

testing of all other modules in progress

Yeah, KDE theme activation is currently broken for any setup where the activation isn't run inside a Plasma session.
I hope that #708 can get merged soon and you can rebase then to make your changes.

I think it'll be sufficient to just guard the if-block in the activator script and the magick-related commands in the themePackage builder with checks on whether the wallpaper is enabled.

got it, thanks

awesome, double thanks

Can you elaborate? I assume the following should be the pattern:

{
  config,
  lib,
  ...
}: let
  target = "<TARGET>";
in {
  options.stylix.targets.${target} = {
    enable = config.lib.stylix.mkEnableTarget target true;

    # TODO: Define config.lib.stylix.mkEnableWallpaper with an appropriate
    # description.
    wallpaper = config.lib.stylix.mkEnableWallpaper target true;
  };

  config = let
    cfg = config.stylix.targets.${target};
  in
    lib.mkIf (config.stylix.enable && cfg.enable) {
      programs.${target} = {
        enable = true;

        wallpaper =
          lib.mkIf
          (cfg.wallpaper && config.stylix.image != null)
          config.stylix.image;
      };
    };
}

Extracting the hard-coded target = "<TARGET>"; variable in each module could be done in a seperate initial commit.

I could quickly do this in a separate PR, but getting my PRs merged takes quiet long since danth is rather slow to respond. However, keeping that commit in this PR will be rather annoying, since we need to resolve breaking changes with new modules introduced in master...

I must have misunderstood what you wanted in #442, i just added an option to every module that uses the wallpaper.

Your approach looks good. Sorry for the confusion.

Cross-post:

the stylix.targets.hyprland.hyprpaper.enable option should probably be renamed to stylix.targets.hyprland.wallpaper.enable in #717.
