ruff.toml

# Ruff config for the repo-tooling Python: tools/** (oracle, catalog, ci,
# codegen, dev, bench, dbcs) and the standalone test drivers under
# tests/ (tests/parity/run_parity.py, tests/codegen/*.py). Invoked from
# the repo root by `make format` / `make format-check`.
#
# The Python binding is NOT governed by this file: ruff's closest-config
# discovery resolves packages/python/** to the [tool.ruff] section in
# packages/python/pyproject.toml. tools/oracle/pyproject.toml carries no
# [tool.ruff] section, so this file applies there too. Keep the two
# configs' conventions in sync (line-length, lint select).
#
# target-version is intentionally omitted: the tooling scripts run on
# whatever python3 the host provides, and pinning here would drift from
# the binding config, which infers its floor from requires-python.

# Ruff's defaults already skip .venv, node_modules, dist, *.egg-info and
# friends; extend with this repo's non-default generated/vendored trees.

# Conservative, auto-fix-friendly set: pycodestyle errors/warnings,
