Args: * `option_or_name`: an `Option` object or its name (`str`). * `value`: the value to be assigned to given option. * `parse_values`: parse the configuration value from a string into its proper type, as per its `Option` object. The default behavior is to raise `ConfigValueValidationError` when the value is not of the right type. Useful when reading options from a file type that doesn't support as many types as Python. * `skip_unknown`: skip unknown configuration options. The default behaviour is to raise `ConfigUnknownOptionError`.

The value which is returned is the first provided among: 1. a user-provided value in the options's ``self._values`` dict 2. a caller-provided default value to this method call 3. the global default for the option provided in ``fontTools.config`` This is to provide the ability to migrate progressively from config options passed as arguments to fontTools APIs to config options read from the current TTFont, e.g. .. code:: python def fontToolsAPI(font, some_option): value = font.cfg.get("someLib.module:SOME_OPTION", some_option) # use value That way, the function will work the same for users of the API that still pass the option to the function call, but will favour the new config mechanism if the given font specifies a value for that option. )rzr!rp_USE_GLOBAL_DEFAULTr6)r r1r6rVrrrrX)s   zAbstractConfig.getcCs ||jSrK)r#rpr`rrrcopyIr\zAbstractConfig.copycCs ||SrK)rX)r r1rrrr[LrazAbstractConfig.__getitem__rScCs |||SrK)rt)r r1r+rrr __setitem__Or\zAbstractConfig.__setitem__cCs||}|j|j=dSrK)rzrpr!)r r1rVrrr __delitem__Rs zAbstractConfig.__delitem__ Iterable[str]cCr^rK)rpr_r`rrrr_VrazAbstractConfig.__iter__rbcCs t|jSrK)lenrpr`rrrrcYrazAbstractConfig.__len__cCs|jjdt|jdS)N(r')r#rr)rpr`rrrrj\szAbstractConfig.__repr__rKrk)rTrqrrrJrsrJ)r1rvr<r)FF)r1rvr+rrrrJrsrJ)r1rvr6rr<r)r1rvr<r)r1rvr+rr<rS)r1rvr<rS)r<rrlrm)rrrrrN classmethodrUrrzrtrrXrr[rrr_rcrjrrrrrs0    ,      r) r __future__rlogging dataclassesrtypingrrrrrr r r r r getLoggerrr{__all__r}rrrrrrrobjectrrrrrrs"  0     ;
