Combinations RF Script from Robofont

Is there anyway to port scripts written for Robofont into Glyphs? Particularly interested in this one https://github.com/danmilne/RoboFont/tree/master/Spacing

https://github.com/mekkablue/Glyphs-Scripts/blob/master/Metrics/Make%20tab%20with%20l etter%20combos.py

Ah thanks!
