flake8-trio

A highly opinionated flake8 plugin for Trio-related problems.

This can include anything from outright bugs, to pointless/dead code, to likely performance issues, to minor points of idiom that might signal a misunderstanding.

It may well be too noisy for anyone with different opinions, that's OK.

Pairs well with flake8-async and flake8-bugbear.

Installation

pip install flake8-trio

List of warnings

• TRIO100: a with trio.fail_after(...): or with trio.move_on_after(...): context does not contain any await statements. This makes it pointless, as the timeout can only be triggered by a checkpoint.
• TRIO101 yield inside a nursery or cancel scope is only safe when implementing a context manager - otherwise, it breaks exception handling.
