Strongly typed, zero-effort CLIs

dcargs

Documentation   •   pip install dcargs

dcargs is a library for typed CLI interfaces and configuration objects.

Our core interface, dcargs.cli(), generates argument parsers from type-annotated
callables: functions, classes, dataclasses, and nested dataclasses and classes.

This can be used as a drop-in replacement for argparse:

with argparse	with dcargs
import argparse parser = argparse.ArgumentParser() parser.add_argument( "--a", type=int, required=True, ) parser.add_argument( "--b", type=int, default=3, ) args = parser.parse_args() print(args.a + args.b)	import dcargs def main(a: int, b: int = 3) -> None: print(a + b) dcargs.cli(main)
