Here's my attempt in overlay form:

self: super: {

  gnomeExtensions = super.gnomeExtensions // {
    put-window = super.stdenv.mkDerivation rec {
      pname = "gnome-shell-extension-put-window";
      version = "26";

      src = super.fetchFromGitHub {
        owner = "negesti";
        repo = "gnome-shell-extensions-negesti";
        rev = "v${version}";
        sha256 = "0a67k096dl0j3q4hkq6n6354mzqd3mkia3zvw2bp0q79hgg6750l";
      };

      uuid = "[email protected]";

      nativeBuildInputs = [
        self.glib
      ];

      postUnpack = ''
        rm source/schemas/gschemas.compiled
        sed -i "1iimports.gi.GIRepository.Repository.prepend_search_path('${self.libwnck3}/lib/girepository-1.0');" source/extension.js source/prefs.js
      '';

      buildPhase = "make -C schemas";

      installPhase = ''
        mkdir -p $out/share/gnome-shell/extensions/${uuid}
        cp -r * schemas $out/share/gnome-shell/extensions/${uuid}
      '';

      meta = with super.stdenv.lib; {
        description = "An gnome-shell extension that makes window movement a lot easier";
        license = licenses.gpl3Plus;
        maintainers = with maintainers; [ chkno ];
        homepage = https://github.com/negesti/gnome-shell-extensions-negesti;
      };
    };
  };
}

The trouble is that it crashes (SEGV).

Steps to Reproduce the crash

1. Go to Move Focus tab in this extension's settings.
2. Click an action, such as "Move the window focus up". It turns blue.
3. Click the keyboard shortcut in the Modify column. It is replaced by "New accelerator..." while it waits for the new keyboard shortcut.
4. Press a new keyboard shortcut, such as <Alt><Shift>f.

Expected Behavior

This becomes the new keyboard shortcut.

Current Behavior

The extension settings window closes. These log messages appear in journalctl:

Looks like missing gsettings schemas. Likely, something akin to this will be required

[stale]

Thank you for your contributions.

This has been automatically marked as stale because it has had no activity for 180 days.

If this is still important to you, we ask that you leave a comment below. Your comment can be as simple as "still important to me". This lets people see that at least one person still cares about this. Someone will have to do this at most twice a year if there is no other activity.

Here are suggestions that might help resolve this more quickly:

1. Search for maintainers and people that previously touched the related code and @ mention them in a comment.
2. Ask on the NixOS Discourse.
3. Ask on the #nixos channel on irc.freenode.net.

The how-to-package-this-gnome-extension? spirit of this issue is obsoleted by #118232, which packaged all the gnome extensions as published in the Gnome extension database rather than building them from sources.
