Python Fire is a library that automatically generates command line interfaces from any Python object, function, or class. It removes the need for manual argument parsing by mapping Python dictionaries, lists, and classes directly to terminal commands. The tool converts Python docstrings into formatted terminal help screens and produces shell scripts to enable tab-completion for available commands. It can wrap existing libraries or external modules to expose their functionality via the terminal without requiring modifications to the original source code. The library supports hierarchical comm

plac is a Python package that can generate command line parameters from function signatures.

docopt-ng is a fork of the original docopt, now maintained by the jazzband project. Now with maintenance, typehints, and complete test coverage!

simple-parsing allows you to transform your ugly argparse scripts into beautifully structured, strongly typed little works of art. This isn't a fancy, complicated new command-line tool either, this simply adds new features to plain-old argparse! Using dataclasses, simple-parsing makes it easier…

Click is a Python framework for building command-line interfaces. It provides a declarative approach to defining command structures, allowing developers to map functions to command-line arguments, options, and nested groups using decorators. The framework handles the complexities of parameter parsing, type validation, and help documentation generation automatically. The project distinguishes itself through its hierarchical context system, which propagates configuration and state across nested commands, and its environment-aware parameter resolution that prioritizes command-line inputs, enviro

This project is a Python terminal user interface library and toolkit designed for building interactive command-line applications. It provides a terminal input manager and a widget toolkit for rendering dashboards, menus, and editors within a terminal emulator. The library enables the creation of full-screen terminal interfaces and interactive shells. It distinguishes itself with advanced input handling, including lexer-based syntax highlighting for visual feedback on code structure and support for industry-standard keyboard navigation modes such as Emacs and Vi. The capability surface covers
