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?

Answer 1

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).
