chrome-gnome-shell: refactor

[jtojnar]

The native connector requires a D-Bus service. For firefox it is also necessary to enable the host connector, for example by setting nixpkgs.config.firefox.enableGnomeExtensions to true.

Unfortunately, it still does not work because the browsers require manifest files, Chromium in /etc/chromium/native-messaging-hosts and Firefox in /usr/lib64/mozilla/native-messaging-hosts.

One way to make it work is to copy the files to local folder:

# Firefox
mkdir ~/.mozilla/native-messaging-hosts
cp $(dirname $(readlink -f $(which chrome-gnome-shell)))/../lib/mozilla/native-messaging-hosts/org.gnome.chrome_gnome_shell.json ~/.mozilla/native-messaging-hosts
# Chromium
mkdir ~/.config/chromium/NativeMessagingHosts
cp $(dirname $(readlink -f $(which chrome-gnome-shell)))/../etc/chromium/native-messaging-hosts/org.gnome.chrome_gnome_shell.json ~/.config/chromium/NativeMessagingHosts

Things done

• Tested using sandboxing
  (nix.useSandbox on NixOS,
  or option build-use-sandbox in nix.conf
  on non-NixOS)
• Built on platform(s)
  • NixOS
  • macOS
  • Linux
• Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
• Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• Fits CONTRIBUTING.md.

Why is the wrapper no longer needed?

[jtojnar]

Switched to wrapGAppsHook. I still wrap PYTHONPATH through wrapPrefixVariables. PATH does not seem to be needed.

I think you could get it working in chromium/chrome out of the box by adding this lines into module:

  environment.etc."chromium/native-messaging-hosts/org.gnome.chrome_gnome_shell.json".source = "${pkgs.chrome-gnome-shell}/etc/chromium/native-messaging-hosts/org.gnome.chrome_gnome_shell.json";
  environment.etc."opt/chrome/native-messaging-hosts/org.gnome.chrome_gnome_shell.json".source = "${pkgs.chrome-gnome-shell}/etc/opt/chrome/native-messaging-hosts/org.gnome.chrome_gnome_shell.json";
