This project is a Python framework for building command-line interfaces by converting standard functions into executable programs. It uses type hints to automatically infer and generate argument parsers, validation logic, and help documentation, allowing developers to define complex terminal applications through simple function signatures.
The framework distinguishes itself through a decorator-driven registration system that enables the construction of hierarchical command trees. It supports dependency injection to manage shared state and runtime configuration across subcommands, and it utilizes reflective metadata inspection to dynamically build help screens and parameter configurations.
Beyond core parsing, the library provides a comprehensive suite of tools for terminal interaction, including support for interactive prompts, secure input collection, and visual feedback like progress indicators. It also handles advanced system integration tasks such as generating shell completion scripts, reading configuration from environment variables, and formatting terminal output with custom styling.
The project is designed to be installed as a standard Python package, enabling developers to expose command-line entry points directly from their modules.
