Handling docstrings when using Argument class about arger HOT 2 CLOSED

The problem is python 3.8 does not have the Annotated type in the typing module so I am not sure how to use Argument in that case.

from arger.

For typing you can use https://pypi.org/project/typing-extensions/#

The above example should be written as

Verbosity = Argument(action='count')

@Arger.init(prog='parse')
def arger(verbosity: Verbosity=0, config_path: Path = DEFAULT_CONFIG_PATH):
    """My Parser.

    Args:
        verbosity: Counted argument, use -v for info and -vv for debug.
        config_path: Path to config file.
    """

The default value should be defined in the function in order to make that parameter optional
