Ms-python Black Formatter not working?

Bug Reports
1

Hello Cursors!

I’m enjoying trying out cursor with a Python project. I’m loving. it. Thank you very much!

The ms-python Black Formatter extension (the one with 2.2M downloads) seems not to work. Worked fine in regular vs code. Not a big deal, but I just got addicted to the auto-formatting.

I tried with the pre-rel v2024.1.10331006, and the rel v2024.0.0

Anything in particular to change or do? Happy to try something.
Thanks!

Same problem here as well… Using latest version:

It seems like something detects file changes, as in the Output window log for Black Formatter I can see ‘textDocument/didChange’ when I type, but it seems like it just never sends commands to reformat? I.e. I can change the file to something which should trigger a reformat, save it, and nothing happens except for the didChange events:

Same. The Black Formatter plugin does not work for me in Cursor.

Hey, unfortunately we are unable to support 3rd party extensions ourselves, but if anyone diagnoses the cause of this issue and it’s something we can fix on our end, do let us know!

Hi, when I run in the terminal, it formats correctly! Do you think this is any useful input?

@danperks So you are saying a plugin that works everywhere but in cursor isn’t a cursor problem? I works at the command-line, it works in vscode. It only doesn’t work in cursor.

Having the same problem, this a huge downside to using cursor given how often LLM’s do silly stuff like leaving empty space everywhere!

I know this might not be actually a solution, but could be a workaround anyway; I started using Ruff instead and it’s working fine.

Still seeing issue. Working around it by running VSCode(!) in parallel for now.
