The elements can be either individual glyphs (by name) or kerning groups (by name), or any combination of the two. Providing the two glyph-to-group mappings accelerates group-lookups. These can be built manually, or with :py:func:`glyphsToGroups`. Args: pair: A tuple, in logical order (first, second) with respect to the reading direction, to query the font for kerning information on. Each element in the tuple can be either a glyph name or a kerning group name. kerning: A dictionary of kerning pairs. groups: A dictionary mapping each group name to its glyph names. fallback: The fallback value to return if no kern is found between the elements in ``pair``. Defaults to 0. glyphToFirstGroup: A dictionary mapping glyph names to the first-glyph kerning groups to which they belong. Defaults to ``None``. glyphToSecondGroup: A dictionary mapping glyph names to the second-glyph kerning groups to which they belong. Defaults to ``None``. Returns: The kerning value between the element pair. If no kerning for the pair is found, the fallback value is returned. Note: This function expects the ``kerning`` argument to be a flat dictionary of kerning pairs, not the nested structure used in a kerning.plist file. Examples:: >>> groups = { ... "public.kern1.O" : ["O", "D", "Q"], ... "public.kern2.E" : ["E", "F"] ... } >>> kerning = { ... ("public.kern1.O", "public.kern2.E") : -100, ... ("public.kern1.O", "F") : -200, ...

Groups are assumed to be compliant with the UFO specification; with the current implementation, if glyphs appear in more than one group anyway, the last group wins. Args: groups: A dictionary mapping each group name to its glyph names. Returns: A tuple of two dictionaries, respectively mapping glyph names to the first- and second-glyph kerning groups to which they belong. Examples:: >>> groups = { ... "public.kern1.O" : ["O", "D", "Q"], ... "public.kern2.E" : ["E", "F"] ... } >>> glyphsToGroups(groups) ({'O': 'public.kern1.O', 'D': 'public.kern1.O', 'Q': 'public.kern1.O'}, {'E': 'public.kern2.E', 'F': 'public.kern2.E'}) r r )itemsr)rrrgroup groupMembersglyphs rr r s2%||~2|   O ,% 1+0!%( 1   o .% 2,1"5) 2 2 1 22__main__)rNN)rrrrrrrrrOptional[StrDict]rr(returnr)rrr)ztuple[StrDict, StrDict]) __future__rtypingrfontTools.annotationsrrrrdictstrStrDictr r __name__doctesttestmodr&rr4s"SS sCx.+/,0 x x x x x ) x * xxv"3J zGOOr&
