sesh / args

args is a zero-dependency, really back to basics, solution to command line arguments in Python.

Usage

import sys
from args import parse_args

args = parse_args(sys.argv[1:])

Arguments can be in one of three formats:

• --option, like --verbose, --debug
• --value=3 to pass a value to an option
• cmd or any other value passed positionally

The output is a Python dictionary with keys for flags and options, and a "[]" key for all other arguments.

Single dash options (-X) and duplicate options (-H "UserAgent: XYZ" -H "Content-type: application/json") are explicitly not supported. Use argparse or click if you need support for parsing these styles of argument.

Examples

> pipenv run python args.py test --verbose --skip=test.py
{
  "--verbose": true,
  "--skip": "test.py",
  "[]": [
    "test"
  ]
}

> pipenv run python args.py run --port=1491:1491 --volume=~/config.cfg:/etc/sonic.cfg
{
  "--port": "1491:1491",
  "--volume": "~/config.cfg:/etc/sonic.cfg",
  "[]": [
    "run"
  ]
}
