        "description": "chatora.dispatch\n================\n\nMultiple argument dispatching for Python.\n\n\n## Usage\nTransform a function into a dispatch generic function, such as the [functools.singledispatch](https://docs.python.org/3/library/functools.html#functools.singledispatch).\nUnlike the [functools.singledispatch](https://docs.python.org/3/library/functools.html#functools.singledispatch), it supports multi-dispatch.\n\n```python\nfrom chatora.dispatch.api import dispatch\n\n\n@dispatch\ndef func(arg0, arg1):\n    return '1st func'\n\n\nassert func(0, 0) == '1st func'\nassert func('0', '0') == '1st func'\n\n\n@func.register\ndef _(arg0, arg1: int):\n    return '2nd func'\n\n\nassert func(0, 0) == '2nd func'\nassert func('0', 0) == '2nd func'\nassert func('0', '0') == '1st func'\n\n\n@func.register\ndef _(arg0: int, arg1: int):\n    return '3rd func'\n\n\nassert func(0, 0) == '3rd func'\nassert func('0', 0) == '2nd func'\nassert func('0', '0') == '1st func'\n```\n\n\nIt partially supports arguments with typing.Union, typing.Optioanl and typing.Any.\ntyping.Any is equivalent to empty annotation.\n\n```python\nfrom chatora.dispatch.api import dispatch\nimport typing\n\n\n@dispatch\ndef func(arg0: typing.Any, arg1: typing.Any):\n    return '1st func'\n\n\n@func.register\ndef _(arg0: typing.Optional[str], arg1: typing.Union[str, list, tuple]):\n    return '2nd func'\n\n\nassert func(0, 0) == '1st func'\nassert func('0', 0) == '1st func'\nassert func('0', '0') == '2nd func'\nassert func('0', []) == '2nd func'\nassert func(None, ()) == '2nd func'\n```\n\n\nIt also partially supports return type annotation.\n\n```python\nfrom chatora.dispatch.api import dispatch\nimport typing\n\n\nclass ResultTuple(tuple):\n    def __new__(cls, *args):\n        return super().__new__(cls, args)\n\n\nclass ResultClass:\n    def __init__(self, a, b):\n        self.a, self.b = a, b\n\n\n@dispatch\ndef func(arg0: typing.Optional[str], arg1: tuple):\n    return '1st func'\n\n\n@func.register\ndef _(arg0: typing.Optional[str], arg1: tuple) -> typing.Sequence[str]:\n    return ['2nd', 'func']\n\n\n@func.register\ndef _(arg0: typing.Optional[str], arg1: tuple) -> typing.Tuple[str]:\n    return ('3rd', 'func')\n\n\n@func.register\ndef _(arg0: typing.Optional[str], arg1: tuple) -> ResultTuple:\n    return ResultTuple('4th', 'func')\n\n\n@func.register\ndef _(arg0: typing.Optional[str], arg1: tuple) -> ResultClass:\n    return ResultClass('4th', 'func')\n\n\nassert func('0', ()) == '1st func'\nassert func('0', (), _return_type=typing.Sequence[str]) == ['2nd', 'func']\nassert func('0', (), _return_type=typing.Tuple[str]) == ('3rd', 'func')\nassert func('0', (), _return_type=ResultTuple) == ResultTuple('4th', 'func')\nassert isinstance(func('0', (), _return_type=ResultClass), ResultClass)\n```\n\n\n\nChangelog\n=========\n\n0.1 (2019-05-01)\n----------------\n- Birth!\n\n",
