connordavenport / RKerning_SmartSet.py

Created February 14, 2024 16:08

An RKerning add on to allow for setting kerning pairs without having to know the group names

	def smartSet(self, pair, value, exceptionType=None):

	'''
	pair must be a tuple, its contents can be a glyphName or a group's name
	value must be an integer, why would you even kern on fractions....
	exceptionType is the level of searching the function will do
	None : use the top level group or glyph names, no exceptions
	g2G : glyph to Group exception
	g2g : glyph to glyph exception
	G2g : Group to glyph exception
