packaging-distribution

What problem does it solve?

This Skill addresses the complexities of building and distributing Python packages, ensuring they can be installed easily and efficiently across diverse operating system and Python versions.

Core Features & Use Cases

• Wheel Building: Generates pre-compiled binary wheels for various platforms (Linux, macOS, Windows) and architectures.
• Distribution Strategies: Differentiates between pure Python and compiled extensions, recommending appropriate build backends like maturin for Rust or scikit-build-core for C/C++.
• Cross-Platform Compatibility: Details how to handle manylinux, musllinux, and macOS platform tags, and leverage the abi3 stable ABI for broader Python version support.
• CI/CD Integration: Provides examples for using cibuildwheel and maturin-action in GitHub Actions for automated wheel building.
• Package Optimization: Offers techniques for reducing package size and improving build performance.
• PyPI Deployment: Guides on setting up pyproject.toml metadata, using TestPyPI, and publishing to the Python Package Index.
• Use Case: You are developing a Python library with a performance-critical Rust extension. This Skill will guide you through configuring maturin, setting up CI to build wheels for all major platforms, and publishing to PyPI.
