Easy overriding of YAML configs

YAML CONFIG OVERRIDE

Why?

YAML Config Override is an extremely lightweight command line interface to your YAML configuration file. Just create a yaml config file, and yaml_config_override will add command line arguments to it automatically. No need to write hundreds of argparse lines!

Installation:

pip install yaml_config_override

Example?

Suppose you have a YAML file test.yaml:

outer:
    x: 0
    inner:
        y: 1
        eveninner:
            z: abc

then you can use it in the code main.py:

from yaml_config_override import add_arguments
import yaml
from pathlib import Path
my_config_path = 'test.yaml'
conf = yaml.safe_load(Path(my_config_path).read_text())
conf = add_arguments(conf)
print(conf)

Now you can call main.py as follows:

python main.py --outer.x 2 --outer.inner.eveninner.z hello

Your program output will be:

{'outer': {'x': 2, 'inner': {'y': 1, 'eveninner': {'z': 'hello'}}}}

Alternatively if you want to pass the config file as a command line argument you can modify the code as follows:

from yaml_config_override import add_arguments
conf = add_arguments()

Now you call main.py as :

python main.py --config test.yaml --outer.x 2 --outer.inner.eveninner.z hello
