Notebook Format Cell//Notebook not working with ruff-lsp

[jamesvrt]

• A minimal code snippet that reproduces the bug.

Create test.ipynb, create a cell with

from abc import (a, b, c
)

Perform Format Select/Cell/Document/Notebook via ctrl+shift+P, the right click menu or the keyboard shortcuts.

No changes observed in the cell.

Performing ruff format test.ipynb on the CLI works as expected.

Including "ruff.nativeServer": "on" in settings.json resolves the issue.

• The current Ruff and VS Code settings (any relevant sections from your pyproject.toml and settings.json).

No ruff.toml or pyproject.toml

Do you see anything in the logs? Refer to the troubleshooting guide.

There was a bug that's been fixed in #485, I'll bump the version of ruff-lsp today to get it out.

[dhruvmanila]

Including "ruff.nativeServer": "off" in settings.json resolves the issue.

What do you mean by this? Like, using the ruff-lsp resolves the issue? But, the issue title says that it doesn't work with ruff-lsp?

[jamesvrt]

What do you mean by this?

Sorry, typo! I meant:

Including "ruff.nativeServer": "on" in settings.json resolves the issue.

I updated the issue. So using the Rust based version is a workaround. I'll try the updated ruff-lsp when it's out.

Sorry, I missed that bit. Logs:

@jamesvrt the new ruff-lsp version is out, can you try it out?

Although I don't see any error in the logs :(

[dhruvmanila]

Also, I'd recommend to switch over to the Rust based server as it has the same functionalities (+ a few more) with no additional installation and high performance :)

[jamesvrt]

How do you get the VSCode extension to use the latest ruff-lsp? The latest extension version still uses the previous ruff-lsp and it doesn't pick up ruff-lsp in my Python environment, only ruff.

BTW, I'm content to use ruff rather than ruff-lsp since it's faster anyway.

Ah right, sorry. I'd need to release a new VS Code extension as well.

[dhruvmanila]

I've released a new extension version which should be available in a couple of minutes.

[HenryDashwood]

Just to say I've been having similar issues as the people above.

adding "ruff.nativeServer": "on" to my workspace's settings.json got ruff formatting my notebook cells again.

However, I'm on the latest version of your extension, v2024.44.0 so should setting that explicitly have been necessary?

I'm also on ruff 0.6.4 everywhere else and in the documentation I think it says that it should default to the native server without explicit setting?

[dhruvmanila]

@HenryDashwood can you share the VS Code settings and Ruff logs? I just tested with 2024.44.0 VS Code with ruff.nativeServer: "off" and it works. And, it doesn't work when using ruff-lsp with 2024.42.0.

[jamesvrt]

ruff-lsp still doesn't work for me with the VSCode extension version 2024.44.0. Logs:

I think we don't support range formatting for Notebooks in ruff-lsp and that's only supported in the native server. Can you try running other formatting operations that apply on the entire notebook and verify? Although it might just be better to completely switch to the native server ;)

[jamesvrt]

"Format Notebook", "Format Cell" and "Format Range" don't work, but "Ruff: Format document" (only available through ctrl+shift+P) does work. I need more granular control than document formatting, so I'll stick with the native server. Thanks!

You can set this to closed if this is expected behaviour, though it might be nice to mention it in the extension page or default to the native server.

[dhruvmanila]

"Format Notebook", "Format Cell" and "Format Range" don't work, but "Ruff: Format document" (only available through ctrl+shift+P) does work.

Oh, that's unexpected and could very well be a bug in ruff-lsp. I think at least "Format Notebook" and "Format Cell" are suppose to work.

Tried to replicate this evening and couldn't I'm afraid. But I guess that does mean it's working!
