About
This skill provides comprehensive documentation for Hatchling, the modern Python build backend implementing PEP standards. Use it when configuring `pyproject.toml`, managing project metadata and dependencies, or troubleshooting build errors for wheel and sdist creation. It covers key capabilities like configuration, version management, build hooks, and migration from setuptools.
Documentation
Hatchling
Overview
Hatchling is a modern, standards-compliant Python build backend that replaces legacy setuptools for package building. It provides clear configuration through pyproject.toml, intelligent defaults, and extensibility through hooks and plugins. This skill enables understanding Hatchling's architecture, configuration options, and build customization capabilities.
Key Capabilities
- Configuration via pyproject.toml: Standards-compliant PEP 621 metadata with sensible defaults
- Build Targets: Wheel and source distribution builds with extensive customization
- Build Hooks: Dynamic code execution during build for artifacts, version management, and compilation
- Version Management: Multiple version sources with automatic version injection
- File Selection: Git-aware VCS integration with glob pattern matching
- Plugins: Extensible architecture for custom builders, hooks, and metadata hooks
