bug: config.lib.nixGL.wrap overrides programs.chromium.commandLineArgs

[DamienCassou]

Are you following the right branch?

• [X] My Nixpkgs and Home Manager versions are in sync

Is there an existing issue for this?

Issue description

In #5355, @Smona, @vigress8, @rycee, @exzombie and a few others collaborated to add the nixGL modules. This is great as it simplifies my configuration. Thank you very much.

Nevertheless, the support for Chromium seems problematic.

Here is an example configuration:

{
  programs.chromium = {
    enable = true;
    package = config.lib.nixGL.wrap pkgs.ungoogled-chromium;
    commandLineArgs = [
      "--extension-mime-request-handling=always-prompt-for-install"
      "--enable-features=ClearDataOnExit"
      "--no-default-browser-check"
      "--incognito"
    ];
  };
}

This generates a chromium executable script which doesn't contain my commandLineArgs anymore.

Workaround: remove config.lib.nixGL.wrap from programs.chromium.package to get the command line arguments back.

Looks like this would happen because the commandLineArgs are added in the buildCommand of chromium, which is overridden by the nixGL wrapper. We may need to try and extend the buildCommand instead of replacing it to fix this in all cases, but we'll have to see if that triggers a bunch of long package builds. Hopefully we won't have to implement a special case for wrapper packages like this one.

I wonder if we could override override on the wrapper derivation returned by nixGL.wrap, so that it basically maps (nixGL.wrap pkg).override { args } to (nixGL.wrap (pkg.override { args })).
