Small RoboFab script to mark glyphs that share the same structure between two fonts

compare_glyph_structure.py

from robofab.world import AllFonts
from robofab.pens.digestPen import DigestPointPen

fonts = AllFonts()

def getDigest(glyph):
	pen = DigestPointPen()
	glyph.drawPoints(pen)
	return pen.getDigest()

for glyph in fonts[0]:
	print glyph.name
	if getDigest(glyph) == getDigest(fonts[1][glyph.name]):
		glyph.mark = 1
		fonts[1][glyph.name].mark = 1
		
for font in fonts:
	font.update()
	
print 'done'

Re-done with digestPen
