Gnome-shell-extension destructor (run on Gnome Shell exit)?

Question

Is there any trick to run my "destructor" code in an extension when Gnome Shell is closing (e.g. computer turning off)? I need to save some state variables to load them again in init() on start.

I need something like function enable() or disable(). Maybe there is some signal being fired which I could connect my code to?

I thought `disable()` was **only** run on extension disabling by user from https://extensions.gnome.org/local/. Now I'm not sure, I'll try, thanks. — Bobas, May 14 '13 at 20:35
It will be run every time your extension get's disabled, which is the case when the shell closes down. — Lukas Knuth, May 15 '13 at 12:20
It works! Thank you very much! BTW the lack of gjs documentation makes it a bit painful and I'm feeling stupid while asking such basic questions :-/ — Bobas, May 16 '13 at 07:46

The disable()-function inside the extension.js-file is called when:

The user disables an extension in a running shell
The shell shuts down or restarts

Keep in mind that it's meant to do UI-manipulation, so you should finish it fast (no heavy lifting).

My experience regarding this topic. disable() is **not** called on system shutdown. Just tested it on ubuntu18 with GNOME Shell 3.34.1. Logout and screen lock **is** triggering it. – wormhit Mar 26 '20 at 14:49
