## Summary I happened to notice that we box `TypeParams` on `StmtClassDef` but not on `StmtFunctionDef` and wondered why, since `StmtFunctionDef` is bigger and sets the size of `Stmt`. @charliermarsh found that at the time we started boxing type params on classes, classes were the largest statement type (see #6275), but that's no longer true. So boxing type-params also on functions reduces the overall size of `Stmt`. ## Test Plan The `<=` size tests are a bit irritating (since their failure doesn't tell you the actual size), but I manually confirmed that the size is actually 120 now.
Ruff Formatter
The Ruff formatter is an extremely fast Python code formatter that ships as part of the ruff
CLI.
Goals
The formatter is designed to be a drop-in replacement for Black, but with an excessive focus on performance and direct integration with Ruff.
Specifically, the formatter is intended to emit near-identical output when run over Black-formatted code. When run over extensive Black-formatted projects like Django and Zulip, > 99.9% of lines are formatted identically. When migrating an existing project from Black to Ruff, you should expect to see a few differences on the margins, but the vast majority of your code should be unchanged.
If you identify deviations in your project, spot-check them against the intentional deviations enumerated below, as well as the unintentional deviations filed in the issue tracker. If you've identified a new deviation, please file an issue.
When run over non-Black-formatted code, the formatter makes some different decisions than Black, and so more deviations should be expected, especially around the treatment of end-of-line comments. For details, see Black compatibility.
Getting started
The Ruff formatter is available as of Ruff v0.1.2. Head to The Ruff Formatter for usage instructions and a comparison to Black.
