アプリケーションアイコン

アプリケーションアイコンは$out/share/icons/hicolorにインストールされる必要があります。

Example code for the now outdated scribus v1.4 app:

{ lib
, stdenv
, fetchurl
, imagemagick
}:

let
  icon = fetchurl {
    url = "https://gist.githubusercontent.com/ejpcmac/a74b762026c9bc4000be624c3d085517/raw/18edc497c5cb6fdeef1c8aede37a0ee68413f9d3/scribus-icon-centered.svg";
    sha256 = "0hq3i7c2l50445an9glhhg47kj26y16svfajc6naqn307ph9vzc3";
  };
in

stdenv.mkDerivation rec {
  pname = "scribus";

  nativeBuildInputs = [
    imagemagick # convert
  ];

  # ...

  postInstall = ''
    for i in 16 24 48 64 96 128 256 512; do
      mkdir -p $out/share/icons/hicolor/''${i}x''${i}/apps
      convert -background none -resize ''${i}x''${i} ${icon} $out/share/icons/hicolor/''${i}x''${i}/apps/${pname}.png
    done
  '';

}

-background none will create transparent icons. Alternative: -background white.
