Load configurations from yaml files with automatic environment variable substitution

Envawareconfig

Load configurations from yaml files with automatic environment variable substitution.

Installation

with pip:

pip install envawareconfig

with poetry:

poetry add envawareconfig

QuickStart

Suppose you have a configuration file like this:

# test-config.yaml
database:
  name: my-database
  user: "${DB_USER:admin}"
  password: "${DB_PASSWORD}"

and that you have set the environment variable DB_PASSWORD to my-secret-password while DB_USER has been left unset.

then running the following code:

# main.py

from envawareconfig import load_config

config = load_config("tests/test-config.yaml")

would result in:

config = {
    "database": {
        "name": "my-database",
        "user": "admin",
        "password": "my-secret-password"
    }
}

Notice that ${DB_PASSWORD} has been expanded and ${DB_USER:admin} used the default value.
