To use Python Pixi with Ruff in Visual Studio Code (VSCode), set up a Pixi virtual environment (venv) and select the Python interpreter location.
Install Ruff in the virtual environment using "pixi add ruff" command and specify the Ruff version (>=0.12.0,<0.13) in the dependencies section of the TOML file.
Install the VSCode extension charliermarsh.ruff and configure the Ruff interpreter by specifying the Python interpreter location in the workspace settings.
After successful configuration, you should see the Ruff output in VSCode, indicating the usage of interpreter and other settings.
