Example: .. code:: python from fontTools.feaLib.parser import Parser parser = Parser(file, font.getReverseGlyphMap()) parsetree = parser.parse() Note: the ``glyphNames`` iterable serves a double role to help distinguish glyph names from ranges in the presence of hyphens and to ensure that glyph names referenced in a feature file are actually part of a font's glyph set. If the iterable is left empty, no glyph name in glyph set checking takes place, and all glyph tokens containing hyphens are treated as literal glyph names, not as ranges. (Adding a space around the hyphen can, in any case, help to disambiguate ranges from glyph names containing hyphens.) By default, the parser will follow ``include()`` statements in the feature file. To turn this off, pass ``followIncludes=False``. Pass a directory string as ``includeDir`` to explicitly declare a directory to search included feature files in. cCsh|] }d|qS)zss%02d.0ir r
