What it is and what it does
pyproject-hooks is a low-level library that provides the plumbing for build frontends to call build-backend hooks specified in a project's pyproject.toml file. It handles the mechanics of discovering and invoking backend operations without implementing the build logic itself.
This is infrastructure for tooling authors, not end users. If you're writing a build frontend or package management tool that needs to invoke build backends, pyproject-hooks handles the subprocess and hook-calling details. The package has no runtime dependencies, making it lightweight to embed in other tools.
Use it for
- Build frontends invoking backend hooks to generate wheels and source distributions
- Package management tools that need to call build-backend hooks programmatically
- CI/CD systems building Python packages with custom build orchestration
- Tools replacing the deprecated pep517 project for build-backend integration
