Thank you for writing the rotator plugin script, it is very convenient to stay in gimp when touching up planet maps.

I am starting the tutorials for gmic scripting available at gmic.eu,
Do you have any advice? or maybe links to helpful resources?

regarding the bug fix:
I suspect that both gmic and gimp have become less tolerant of sintax variations.
here are my versions:
