Run on any function automatically about enforce

[RussBaz]

Hmmm. Yes, I like how this sounds. I think it might be especially useful in debugging already running systems. However, I am not yet sure how to implement it correctly right now. I need to focus on few other problems first.

PS. Thanks for noting! I hope this project can help you at least one day.

Try this:

def CheckInputTypes(func):
    def wrapper(*args, **kwargs):

        for arg in args:
            ArgValue = next(iter(locals()['args']))
            ArgParamType = next(iter(func.__annotations__.keys()))

            if isinstance(ArgValue, func.__annotations__[ArgParamType]) is False:
                raise TypeError(
                    "Arg: {0} in function {1} is not of type {2}".format(
                        repr(ArgParamType), repr(func.__name__),
                        func.__annotations__[ArgParamType]))

        for kwarg in kwargs:
            KwargValue = locals()['kwargs'][kwarg]

            if isinstance(KwargValue, func.__annotations__[kwarg]) is False:
                raise TypeError(
                    "Kwarg: {0} in function {1} is not of type {2}".format(
                        repr(kwarg), repr(func.__name__),
                        func.__annotations__[kwarg]))

        RanFunc = func(*args, **kwargs)
        if isinstance(RanFunc, func.__annotations__['return']) is False:
            raise TypeError(
                "Return value {0} in function {1} is not of type {2}".format(
                    repr(RanFunc), repr(func.__name__),
                    func.__annotations__['return']))

        return RanFunc
    return wrapper
