Utilities for benchmarking Ruff.

Run ./scripts/benchmarks/setup.sh to clone the benchmarking target (CPython).

If you're looking to benchmark Ruff against other tools, you'll also need to run uv venv --project ./scripts/benchmarks, activate the venv and finally uv sync --project ./scripts/benchmarks to create a virtual environment with the required dependencies.

Run ./scripts/benchmarks/run.sh to run Ruff over the target repo (CPython). The ./scripts/benchmarks folder contains a few other benchmarks (e.g., scripts/benchmarks/run_comparisons.sh compares Ruff to a variety of other tools).

The Vega specification for the benchmark plot depicted in the root README can be found at scripts/benchmarks/graph-spec.json. You can render this JSON spec in the Vega Editor.

The images seen in the README are generated by exporting the rendered Vega spec as SVG (at around 688px wide) and manually bolding the Ruff title and benchmark time. The dark mode variant is generated by changing the fill from fill="#333333" to fill="#C9D1D9".
