Takayi

Type hints for python 2.X.

takayi means high in japanese.

Usage

from takayi.parser import Parser, typehints

parser = Parser()

# default to enable typehints
# disable typehints
parser.set_disable()

# enable
parser.set_enable()

# ==================================================
@typehints(parser)
def get_sum(x, y):
    # type: (int, int) -> int
    return x + y

_sum = get_sum(1, 2)  # result should be 3

# takayi.exc.ParameterTypeError: Expect => [<type 'int'>, <type 'int'>], Actually => [<type 'int'>, <type 'str'>]
_err_sum = get_sum(1, 'hello')


# ==================================================
@typehints(parser)
def test(x, y=1):
    # type: (int, y: int) -> int
    return x + y

assert test(1, y=10) == 11


# ==================================================
class Node(object): pass

node = Node()


@typehints(parser, attach_cls=Node)
def get_node():
    # type: () -> Node
    return node

TODO

• Support kwargs type check
• More types. FYI: pep484
