ordered-argparse

ordered_argparse

Version of Python's standard library's argparse which also remembers the order of command line arguments.

Installation

Install with pip install ordered_argparse.

Usage

Create an instance of ArgumentParser as usual. Use namespace=ordered_argparse.OrderedNamespace(). Access arguments in declaration order by calling parser's .ordered() method.

import ordered_argparse

parser = ordered_argparse.ArgumentParser()
parser.add_argument("--foo", action="store_true", help="foo")
parser.add_argument("--bar", action="store_true", help="bar")

# Use OrderedNamespace when parsing CLI arguments
args = parser.parse_args(["--foo", "--bar"], namespace=ordered_argparse.OrderedNamespace())

# Access ordered arguments by calling .ordered()
for arg in args.ordered():
    print(f"{arg}")

Compatibility with argcomplete

ordered_argparse only works with argcomplete as long as you don't use subparsers. If you use subparsers, you need ordered_argcomplete.
