cargparse 0.0.7

Configuration file parsing with argparse.

cargparse :blue_car:

A lightweight library to parse configuration files using argparse.

• Robust type validation with argparse
• Supports nested arguments with recursive calls to argparse
• No syntax to learn, just use argparse!! :rocket:

Currently supports yaml/yml and json files. ini, toml, and others are under development.

Contributions welcome! :handshake:

Installation

pip install cargparse

Usage

Given config.yaml...

text: hello world
decimal: 0.5
boolean: False

...your script might look like this...

import argparse
import cargparse

parser = argparse.ArgumentParser()
parser.add_argument('--text', type=str)
parser.add_argument('--decimal', type=float)
parser.add_argument('--boolean', type=lambda x: eval(x))
args = cargparse.YAML(parser=parser, filename='config.yaml')

...which returns a Namespace object, just like ArgumentParser.parse_args()!

>> args
Namespace(text='hello world', decimal=0.5, boolean=False)
>> args.text
'hello world'
>> type(args.decimal)
<class 'float'>

:boom: Nested dictionaries are Namespace objects, too!
