ConfigArgParse

ConfigArgParse is a drop-in replacement for Python's standard `argparse` module, enhancing it with the ability to load configuration options from command-line arguments, environment variables, and configuration files (INI, YAML, TOML formats). It offers a unified API to define, document, and parse settings from multiple sources with a clear precedence order (command line > environment variables > config file values > defaults). The library is actively maintained, with its current version being 1.7.5.
