Class based argument parser

Class-Argparse

Class based argument parser to simplify writing CLIs that have lots of options

How to use

from typing import Literal

from class_argparse import ClassArgParser


class Main(ClassArgParser):
    """
    # ClassArgParser
    example description
    """

    def __init__(self) -> None:
        super().__init__(name="Class ArgParser")

    def no_args(self):
        print("no_args")

    def no_args_with_desc(self):
        """
        some desc text goes here
        second line of desc
        """
        print("no_args_with_desc")

    def some_args(self, arg: str):
        print("some_args", arg)

    def default_values(self, arg: str, default: int = 0):
        print("default_values", arg, default)

    def list_values(self, values: list[str]):
        print("list_values", values)

    def untyped_arg(self, untyped):
        print("untyped_arg", untyped)

    async def async_func(self, arg: str):
        print("async_func", arg)

    def literal_options(self, arg: Literal["a", "b"]):
        print("literal_options", arg)


if __name__ == "__main__":
    Main()()

How this works

1. The class ClassArgParser extends ArgumentParser
2. The initialization function finds add adds all the methods on child classes that are public i.e. their names don't start with __
3. The object of the class is called and after identifying whether the function being called it is async or sync it runs the function accordingly
