Application configuration engine
Project description
Python helper class to ingest and serialize app-specific configuration
Provides a self-contained (no dependencies outside the standard library), Python 2 and 3 compatible configuration manager. Automatically saves and restores your application’s configuration in your user home directory. Uses JSON or (optionally) YAML for serialization. Supports dict-like methods and access semantics.
Installation
If your package does not permit dependency management, you can copy the Config class directly into your application from https://github.com/kislyuk/tweak/blob/master/tweak/__init__.py. Otherwise:
pip install tweak
Synopsis
from tweak import Config
config = Config()
config.host, config.port = "example.com", 9000
config.nested_config = {}
config.nested_config.foo = TrueAfter restarting your application:
config = Config()
print(config)
>>> {'host': 'example.com', 'port': 9000, 'nested_config': {'foo': True}}
Using an argparse.Namespace object returned by argparse.parse_args():
parser = argparse.ArgumentParser()
...
args = parser.parse_args()
if args.foo is not None:
config.foo = args.foo
elif "foo" not in config:
raise Exception("foo unconfigured")
config.update(vars(args))
Using YAML:
config = Config(use_yaml=True) ...
