There are many configuration management/definition systems. This one is mine. This is an overview. There are also more formal docs.
A set of simple tools to build a configuration system with
The first set are 'sources':
- DictSource, which takes values from a python dict and is useful for defaults
- SubsetSource, which returns a subset of another source, to help with merge precedence
- OSEnvironSource, which parses config values from os.environ into hierarchical dictionaries
- YamlFileSource, which parses a yaml file into hierarchical dictionaires (
pip install mincfg[yaml]for support) - INIFileSource, which understands INI files (based on configobj) (
pip install mincfg[ini]for support) - DotEnvSouce, which understands .env files (based on python-dotenv) (
pip install mincfg[env]for support)
The second tool is:
- MergedConfiguration: which merges multiple configuration sources into a coherent whole
Yes, much more could be done:
- required keys
- value validation
- default parsers
- default default values (that .get() without a default would default to)
- more file types (json, ... xml?)
- sphinx/rtd docs
... PRs accepted!
Much inspiration - and the .get() signature - is taken from everett, but the implementation is all mine.
