# Benchmark the Ruff formatter's performance against a variety of similar tools.
|
|
#
|
|
# Expects to be run from the repo root after invoking `cargo build --release`,
|
|
# in an environment with access to `black`, `autopep8`, and `yapf` (most recently:
|
|
# `black` v23.9.1, `autopep8` v2.0.4, and `yapf` v0.40.2, on Python 3.11.6, the
|
|
# most recent combination of versions for which Black provides compiled wheels at
|
|
# time of writing).
|
|
#
|
|
# Example usage:
|
|
#
|
|
# ./scripts/benchmarks/run_formatter.sh ~/workspace/zulip

|
|
# In each case, ensure that we format the code in-place before invoking a given tool. This ensures
|
|
# a fair comparison across tools, since every tool is then running on a repository that already
|
|
# matches that tool's desired formatting.
|
|
#
|
|
# For example, if we're benchmarking Black's preview style, we first run `black --preview` over the
|
|
# target directory, thus ensuring that we're benchmarking preview style against a codebase that
|
|
# already conforms to it. The same goes for yapf, autoepp8, etc.
|
|
|
|
# Benchmark 1: Write to disk.
