with-argparse 0.0.2

A simple but handy Python library to generate a `argparse.ArgumentParser` object from a type-annotated method

with-argparse

with-argparse is a very simple and tiny package adding support to create and apply argparse.ArgumentParser objects automatically using the type annotations from a given python method:

from pathlib import Path
from with_argparse import with_argparse

@with_argparse
def sample_method(
    text_input: str,  # required argument
    another_text_input: str = None,  # default argument
    output_dir: Path = None,
    flag: bool = False,
):
    pass

sample_method()

will generate the argparse output:

usage: scratch_2.py [-h] --text_input TEXT_INPUT
                    [--another_text_input ANOTHER_TEXT_INPUT]
                    [--output_dir OUTPUT_DIR] [--flag]

Boolean values

• A True boolean default field flag is converted to --no_flag

Configurability

• with_opt_argparse allows to override some of the default settings used
