Format cell on run like the nb_black extension does.

[nickeubank]

One of my favorite features of vscode (and other good editors) is format on save. Obviously that's not feasible for notebooks because they aren't linear and so a formatter would struggle if it tried to parse everything every time the notebook was saved. But there is a solution that's like format on save for notebooks: format on run.

Now that notebook cells can be formatted, would it be possible to create a setting where each cell is formatted when it's run? It's already available in regular jupyter notebooks thanks to nb_black, and I'd love to see it in VS code notebooks.

Thanks for the suggestion. We'll look at it in our weekly triage. It will probably need a bunch of upvotes before it's considered.

Thanks! Since black catches syntax errors, it's kinda related to this too, no? https://github.com/microsoft/vscode-jupyter/issues/1482

+1 code format inside cell is the last reason I still keep jupyter-lab on my system.

Just FYI, black now supports Jupyter Notebooks and even has a black.format_cell function, so that could help here

That would be very helpful indeed! Thanks for considering!

Any news regarding this?

I would personally prefer to have the formatting done on save, and not when running a cell.

Sorry but it's not planned at the moment.

Spent 1/2 hour trying to figure out why it's not working... some hint in the config section would be nice.

Could you please reconsider this again?

Cheers.

You can add the "notebook.formatOnSave.enabled": true setting as found here.

This feature will be in the next insiders build, and can be enabled by adding the following into your settings json: "notebook.formatOnCellExecution": true

Awesome, thanks!
