>>> lib = {"public.glyphOrder" : ["A", "C", "B"]} >>> fontLibValidator(lib) (True, None)
>>> lib = "hello" >>> valid, msg = fontLibValidator(lib) >>> valid False >>> print(msg) The lib data is not in the correct format: expected a dictionary, ...
>>> lib = {1: "hello"} >>> valid, msg = fontLibValidator(lib) >>> valid False >>> print(msg) The lib key is not properly formatted: expected str, found int: 1
>>> lib = {"public.glyphOrder" : "hello"} >>> valid, msg = fontLibValidator(lib) >>> valid False >>> print(msg) public.glyphOrder is not properly formatted: expected list or tuple,...

>>> lib = {"public.markColor" : "1,0,0,0.5"} >>> glyphLibValidator(lib) (True, None)

- fontTools.ufoLib.validators.groupsValidator(value)[source]
Check the validity of the groups. Version 3+ (though it’s backwards compatible with UFO 1 and UFO 2).

>>> groups = {"public.awesome" : ["A"]} >>> groupsValidator(groups) (True, None)
>>> groups = {"public.kern1." : ["A"]} >>> valid, msg = groupsValidator(groups) >>> valid False >>> print(msg) The group data contains a kerning group with an incomplete name. >>> groups = {"public.kern2." : ["A"]} >>> valid, msg = groupsValidator(groups) >>> valid False >>> print(msg) The group data contains a kerning group with an incomplete name.
>>> groups = {"public.kern1.A" : ["A"], "public.kern2.A" : ["A"]} >>> groupsValidator(groups) (True, None)
>>> groups = {"public.kern1.A1" : ["A"], "public.kern1.A2" : ["A"]} >>> valid, msg = groupsValidator(groups) >>> valid False >>> print(msg) The glyph "A" occurs in too many kerning groups.
- fontTools.ufoLib.validators.identifierValidator(value)[source]
Version 3+.
