Introduction

resconfig is a minimalistic application configuration library for Python. It is a thin wrapper around nested dict objects with added features that make it easy to deal with the data structure as a centralized storage of application configuration.

ResConfig supports

• multiple configuration file formats: INI, JSON, TOML, and YAML;

• environment variables: Configuration can be easily overridden with environment variables;

• command-line arguments: Configuration can be easily overridden with ArgumentParser command-line arguments.

• “.”-delimited nested keys: config["foo.bar"] is equivalent to config["foo"]["bar"].

The advanced usage of ResConfig allows:

• Dynamic reloading of configuration at run time: Watch functions can be attached to any keys within the configuration to trigger actions to manage resources.
