This repository serves as a pre-commit hook configuration for Ruff, an extremely fast Python linter and formatter. It defines three pre-commit hooks: `ruff-check`, `ruff-format`, and a legacy `ruff` alias. The core operational code is a single Python script (`mirror.py`) that automates version mirroring: it fetches the latest Ruff release from PyPI and updates version strings in `pyproject.toml` and `README.md`. A GitHub Actions workflow runs this script on a schedule (every 4 hours), commits changes, tags releases, and creates GitHub releases. The repository is a minimal, well-structured wrapper that enables installing Ruff via pre-commit hooks. There is no application logic beyond the mirror script; the project's value is in its configuration and automation pipeline for staying in sync with upstream Ruff releases.
