Hi all,
I’m to write a script to use with RoboFab that will work like the fontlab function “Copy to composites” from the preview window when a glyph is used in other composites.
This fiunction works fine but I was trying to produce something that would update all the metrics in composites in on go without having to go through each glyph.
I thought something like this might work,

from robofab.world import CurrentFont
f = CurrentFont()
f['Itilde'].leftMargin = f['I'].leftMargin
f['Imacron'].leftMargin = f['I'].leftMargin
f['Ibreve'].leftMargin = f['I'].leftMargin
f['Iacute'].leftMargin = f['I'].leftMargin
f['Icircumflex'].leftMargin = f['I'].leftMargin
f['Idieresis'].leftMargin = f['I'].leftMargin
f['Igrave'].leftMargin = f['I'].leftMargin
f['Idotaccent'].leftMargin = f['I'].leftMargin
f['Itilde'].rightMargin = f['I'].rightMargin
f['Imacron'].rightMargin = f['I'].rightMargin
f['Ibreve'].rightMargin = f['I'].rightMargin
f['Iacute'].rightMargin = f['I'].rightMargin
f['Icircumflex'].rightMargin = f['I'].rightMargin
f['Idieresis'].rightMargin = f['I'].rightMargin
f['Igrave'].rightMargin = f['I'].rightMargin
f['Idotaccent'].rightMargin = f['I'].rightMargin
f.update()
This produces sidebearings including the added accents in the case of the Itilde, Imacron etc.
When using the Copy to Composites function in FL it produ
