Mypy.parse needs error messages about mypy HOT 5 CLOSED

With latest mypy, consider passing raise_on_error=True? Don't think mypy really promises any API here, but feel free to open a PR.

Your escaping is wrong, causing your string literal to be unterminated. This is just the error ast.parse will give you too, doesn't even need to involve mypy

from mypy.

The errors object is modified on each call to parse, so I have modified parse_str

def parse_str(stub: str) -> Union[MypyFile, str]:
    options = Options()
    errors = Errors(options)

    ast = parse(stub, 'test', None, errors, options)

    if 'test' not in errors.error_info_map:
        return ast, ''
    else:
        return ast, errors.error_info_map['test'][0].message

I get an "unterminated string literal" error message but each line in the source code seems to be terminated. I am not sure why.

@hauntsaninja would you mind pointing out where the wrong escaping happens?

\n

Possible solution is to use a raw string. The \n inside the docstring inside the code sample gets expanded into a newline too early.
