Bug report

Source:

An error replacement happens in:

repr(annotation).replace('typing.', '')

Suppose that I define a class or Protocol under foo/typing.py:

class A:
    pass

Then Union[int, A] will turn to Union[int, foo.A], but expected result is Union[int, foo.typing.A]

Any module with suffix like xxtyping will be replaced, such as nptyping.

Solution

Replace the line to:

        def repl(match):
            text = match.group()
            if text.startswith('typing.'):
                    return text[len('typing.'):]
            return text
        return re.sub(r'[\w\.]+', repl, repr(annotation))
