Simple configuration file loader

Why

Modern configuration file is more and more complex, flexible and readable, but had no option to pass environment variables. This project aim to simplify usage of the configuration file and environment variables for production and development, with easy dictionary like access

Supported files: ini, yaml, json & cfg

Install

pip install smart-config

Basic usage

Let's assume we had a project with this config file system.yaml

# system.yaml
database:
    host: ${DATABASE_HOST:localhost}
    port: ${DATABASE_PORT:27017}
    username: ${DATABASE_USER:user}
    password: ${DATABASE_PASSWORD:password}
    database: ${DATABASE}

and environment variables set to

DATABASE_HOST=mongodb://xxx.xxx.xxx.xxx
DATABASE_USER=mongo
DATABASE_PASSWORD=changeit
DATABASE=Demo

parse file with ConfigLoader

from smart_config import ConfigLoader

# read file system.yaml and parse config
env = ConfigLoader('system.yaml').get_config()

# access whole database section
print(env['database'])

# {
# 'database': 'test',
# 'host': 'mongodb://xxx.xxx.xxx.xxx',
# 'user': 'mongo'
# 'password': 'changeit',
# 'port': 27017,
# 'database': 'demo'
# }

# access database host value
print(env['database']['host'])

# >> mongodb://xxx.xxx.xxx.xxx

# access database port value returns default value as DEFAULT_PORT is not set in environment
print(env['database']['port'])

# >> 27017
