Ruff's VSCode extension doesn't recongnize terminal command executions in jupyter notebooks

[juanbfactored]

Summary

The ruff linter VS Code extension assigns syntax errors to any line using the terminal magic of "!" in any Jupyter notebook cell. For example, if I have a cell like this:

!brew install ruff

The extension will highlight this line and tell me I have a syntax error. For more reference see the image below

Is this in an unsaved file/buffer possibly? I'm looking at the filename ruff_demo.ipynb#..... and thinking the bit after # may be confusing our file type detection.

I'm not able to reproduce this with a regular filename like try.ipynb.

It is not an unsaved file or buffer. I cloned a repo and opened this notebook in VS Code. To make sure it wasn't related to any issues with the file, I closed the tab with the notebook, quit VS Code, and reopened it. The error is still there.

Additionally, I created another notebook test.ipynb and the same incorrect error was highlighted when I opened it in VS Code.
