Trailing white space introduced

[peterjc]

Tools like flake8 will complain about trailing white space (W291), and it seems pyment sometimes introduces white space.

As a specific example, take the test.py example from the README.rst file which produces the following:

        def func(param1=True, param2='default val'):
            """Description of func with docstring groups style.

            :param param1: descr of param1 that has True for default value
            :param param2: descr of param2 (Default value = 'default val')
            :returns: some value
            :raises keyError: raises key exception
	    :raises TypeError: raises type exception

	    """
            pass

        class A:
            """ """
            def method(self, param1, param2=None):
	        """

	        :param param1:
                :param param2:  (Default value = None)

	        """
                pass

There is a trailing space on the line :param param1: in the class A method, both here and in the patch itself.

I have confirmed this running pyments test.py locally using v0.3.2

Other examples (which I have not reduced to a minimal test case) introduce "blank lines" with the default indentation spaces included. I had a look at the code, but was confused by the multiply defined lambda function with_space which seems might be to blame.

Hi @peterjc,
It was intended to add a trailing space. It is to enjoin the user to edit the missing descriptions.
Perhaps an option should allow to avoid this?

[peterjc]

I assumed this was a mistake, rather than at least some of these cases being deliberate.

Personally I avoid trailing white space (as per the flake8 defaults), so would prefer not to have trailing white space added. However, it is relatively easy to remove automatically (eg with sed).

[dadadel]

Perhaps adding an option allowing to insert or not the white space should be added.

Even when I specify a config trailing_space= I still get trailing spaces after the param

def solution(name: str, age: int, gender: str = 'M') -> bool:
    """

    :param name: str:⚪
    :param age: int:⚪
    :param gender: str:  (Default value = 'M')

    """
    return True
