pysyva

Pysyva is a Python library designed for creating and managing command-line interfaces (CLIs). It aims to simplify the process of building interactive and user-friendly command-line applications. The library provides a declarative approach to defining commands, arguments, and options, allowing developers to focus on the logic of their application rather than the intricacies of argument parsing.

Key features of Pysyva include automatic help message generation, type casting for arguments, support for various argument types such as positional arguments, optional arguments, and flags, and the ability to define nested commands for more complex CLI structures. It also offers features for validating input and handling errors gracefully, contributing to more robust CLI applications. Pysyva is written in pure Python and does not have external dependencies, making it easy to install and use. The library's design emphasizes readability and maintainability, facilitating the development of CLI tools of varying complexity. It is often chosen by developers who prefer a straightforward and Pythonic way to build their command-line interfaces.
