Conf

✓ import opset

✗ from opset import Conf

Define a typed configuration schema with environment variable overrides.

from opset import Conf # Define configuration schema with defaults and env variable overrides conf = Conf( db_host=Conf.var(type=str, default='localhost', env='DB_HOST'), db_port=Conf.var(type=int, default=5432, env='DB_PORT'), debug=Conf.var(type=bool, default=False, env='DEBUG') ) # Access config values print(f"DB Host: {conf.db_host}, Port: {conf.db_port}, Debug: {conf.debug}")

Known issues

breakingIn opset 4.x, Conf.var signature changed: 'default' is now required for all types, and 'required' parameter replaced 'mandatory'.

fix

Update calls to Conf.var: add default=... and use required=True instead of mandatory=True.

affects: <4.0.0

deprecatedThe from_env=True parameter is deprecated in favor of passing env directly to Conf.var or using Env class.

fix

Use env='VAR_NAME' instead of from_env=True.

affects: >=4.0.0,<4.3.0

gotchaConf.var with type=bool does not accept 'true' or 'false' strings; only '1', '0', 'true', 'false' (case‑insensitive) work. 'yes'/'no' cause a validation error.

fix

Use 'true' or 'false' (lowercase) for bool environment variables.

affects: all

gotchaNested configuration (Conf with child Conf) changed syntax in 4.x; sub‑configs must be defined via Conf.child() instead of direct instantiation.

fix

Use conf = Conf(child=Conf.child(...)) instead of conf = Conf(child=Conf(...)).

affects: >=4.0.0
