I mentioned Processing --- there isn't an interactive graphical front-end --- it's a text editing/result window pair. Another concern is the last time I looked into it I couldn't get the precision necessary --- has that changed? Probably I should just use Hypernext Studio: https://tigabyte.com/ https://tigabyte.com/ but I don't like that it's closed source/very small company (one person?) and not really cross-platform.
