Automatically detect when uv is being used

Feature

If .venv/bin/python exists in the root of the project (where the pyproject.toml file is), then automatically use it as the python executable with priority over /usr/bin/python.

Pitch

This feature would make uv work out of the box, instead of a user having to figure out that they need to add --python-executable=.venv/bin/python to the mypy command that they run.

Alternative solutions

There could also be a help note if .venv/bin/python exists and mypy cannot find implementations or library stubs for the majority of the imports, that suggests adding --python-executable=.venv/bin/python to the mypy command.

Commencez par suivre l’option existante --python-executable et la manière dont mypy localise la racine du projet contenant pyproject.toml. Vérifiez le comportement lorsque .venv/bin/python existe, notamment sa priorité par rapport à /usr/bin/python, et ajoutez une couverture pour la sélection automatique ; le travail est terminé lorsque les projets uv fonctionnent sans l’option supplémentaire.
