# shellcheck shell=bash

# Setup hook that installs specified desktop items.
#
# Example usage in a derivation:
#
#   { …, makeDesktopItem, copyDesktopItems, … }:
#
#   let desktopItem = makeDesktopItem { … }; in
#   stdenv.mkDerivation {
#     …
#     nativeBuildInputs = [ copyDesktopItems ];
#
#     desktopItems =  [ desktopItem ];
#     …
#   }
#
# This hook will copy files which are either given by full path
# or all '*.desktop' files placed inside the 'share/applications'
# folder of each `desktopItems` argument.
