dcargs 0.1.9

Strongly typed, zero-effort CLIs

dcargs

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

pip install dcargs

Our core interface generates argument parsers from type-annotated callables. In the simplest case, 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)

The broader goal is to enable replacing configuration frameworks like hydra, gin-config, and ml_collections with hierarchical structures built using standard Python dataclasses and type annotations.
