Compact argparse definition

@dataclass
class MyArguments:
   a  : str                                                    # Positional
   b  : int                = 20                                # My argument
   c  : bool               = False                             # My argument
   d  : int                = choice(0, 1, 2, 3, 4, default=1)  # choices
   e  : List[int]          = argument(default=[0])             # list
   f  : Optional[int]      = None                              # Optional
   p  : Tuple[int, int]    = (1, 1)                            # help p
   g  : Color              = Color.RED                         # help g
   s  : SubArgs            = SubArgs                           # helps group
   cmd: Union[cmd1, cmd2]  = subparsers(cmd1=cmd1, cmd2=cmd2)  # Command subparser

parser = ArgumentParser()
parser.add_arguments(MyArguments)
args = parser.parse_args()

Lower level interface, that gives you back all of argparse power

@dataclass
class SubArgs:
   aa: str = argument(default="123")


@dataclass
class cmd1:
   args: str = "str1"


@dataclass
class cmd2:
   args: str = "str2"


@dataclass
class MyArguments:
   a: str                  = argument(help="Positional")
   b: int                  = argument(default=20, help="My argument")
   c: bool                 = argument(action="store_true", help="My argument")
   d: int                  = argument(default=1, choices=[0, 1, 2, 3, 4], help="choices")
   e: List[int]            = argument(default=[0], help="list")
   f: Optional[int]        = argument(default=None, help="Optional")
   p: Tuple[int, int]      = argument(default=(1, 1), help="help p")
   g: Color                = argument(default=Color.RED, help="help g")
   s: SubArgs              = group(default=SubArgs, help="helps group")
   cmd: Union[cmd1, cmd2]  = subparsers(cmd1=cmd1, cmd2=cmd2)

parser = ArgumentParser()
parser.add_arguments(MyArguments)
args = parser.parse_args()
