I have this simple Robofab script here I wrote to shift the vertical position
of subscript glyphs.
I haven't used it for a while but it has stopped working now.
I get an error message saying - NotImplementedError
Is there a reason why this has started to happen? can I fix it?
from robofab.world import CurrentFont
from robofab.interface.all.dialogs import AskString
f = CurrentFont()
glyph = [
down = int(AskString('Move Down'))
for g in glyph:
f[g].mark = 140
