A simple but handy Python library to generate a `argparse.ArgumentParser` object from a type-annotated method
Project description
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 fieldflag
is converted to--no_flag
Configurability
with_opt_argparse
allows to override some of the default settings used
