[Bug]: Presets not listed on home-manager based install

[de-odex]

I have:

• Searched if this issue hasn't been reported yet.
• Verified that I am using the latest version (see Widget settings > About page or top right corner for version 1.1.0 and later), should be the same as https://github.com/luisbocanegra/plasma-panel-colorizer/releases/latest
  • Listed 2.3.0

Install method used:

• Using Plasma's "Add new widget" (KDE Store)
• AUR
• Nix package
• Manually from the latest source code

Describe the bug
No presets (neither user-made nor built-in)

Steps to reproduce

1. Install via home-manager
2. Click on 'Refresh presets'

Observed Result

Additional context
This is a nixpkgs error, actually. I think the script needs to be exposed in some sense, I just don't have the time to investigate right now, sorry

Hi @de-odex thanks for reporting this.

Seems so yeah, there is probably a way to mark that file as executable in the nix package, similar to what I did for the AUR one: https://aur.archlinux.org/cgit/aur.git/commit/?h=plasma6-applets-panel-colorizer&id=eab7fa66bd9b98f7dedae8d2144aafc5ad602bba

@HeitorAugustoLN since you were the original packager and still appear as maintainer maybe you can help us with this? Hope the ping doesn't bother you :)

[HeitorAugustoLN]

Thanks for reporting this! And thanks for the ping @luisbocanegra, it didn't bother me. I opened a PR fixing the package in nixpkgs (NixOS/nixpkgs#383192). While it is not merged, you can add an overlay fixing it:

{
  nixpkgs.overlays = [
    (final: prev: {
      plasma-panel-colorizer = prev.plasma-panel-colorizer.overrideAttrs {
        postInstall = "chmod 755 $out/share/plasma/plasmoids/luisbocanegra.panel.colorizer/contents/ui/tools/list_presets.sh";
      };
    })
  ];
}

I probably didn't see this script while updating to 1.0.0 😅

[HeitorAugustoLN]

@de-odex in the PR, I also added a patch that makes the dbus service work by default, without having to configure the python executable and glib. Could you also test it to see if works correctly?

[de-odex]

Thank you for the quick response. I'll be able to try it perhaps tomorrow or the next day

Also faced this issue. Installed it from the unstable channel, though I didn't use home-manager. Confirmed that it's the latest version, 2.4.3. No presets were showing up, either built-in or user added.

Then I put the overlay mentioned above in configuration.nix, and now it seems to be working fine. So all's good, but just thought I'd mention that this issue still persists on fresh Nix installs.
