Conflow
Conflow organizes layered configurations for Python applications. Conflow allows you to use default settings and extend or override it via merging settings from different sources: - Python dictionaries - Files: yaml, json, ini - Environment variables
Quickstart
pip install conflow
Usage
import os
from conflow import Config, from_env, from_yaml
DEFAULT_SETTINGS = {
'db': {
'master': {
'host': 'localhost',
'port': 5432,
},
'slave': {
'host': 'localhost',
'port': 5433,
}
}
}
config = Config().merge(DEFAULT_SETTINGS)
assert config.db.master.host() == 'localhost'
os.environ['APP_DB__MASTER__HOST'] = 'remote_host'
env_settings = from_env('APP')
config = Config().merge(DEFAULT_SETTINGS).merge(env_settings)
assert config.db.master.host() == 'remote_host'
develop_settings = from_yaml('config/develop.yaml', required=False)
config = Config().merge(DEFAULT_SETTINGS).merge(env_settings).merge(develop_settings)
assert config.db.master.host() == 'develop'
Motivation
If you are tired of making local, test, stage and production profiles in each project, then Conflow is for you. Conflow allows you to fetch and merge configs from different places - yaml files, environment variables etc.
