MinCfg

the Minimum Configuration Handling System

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.
