Be able to save a notebook without saving output

[rchiodo]

It was 1 liner since I used Git and VS Code on it.
Any way to restore the indention as you described?

Maybe add an option to auto do it on save? As this 1 line mode make it Git unfriendly.

By the way, it would be also great to have "Save without Output on HD" mode (Git friendly save mode).

This is really a vscode core thing.

this could be very useful, particularly when we are handling sensitive info that we don't want to commit on git repos.

I am also looking for a way to do this. I wanted to switch to using VS Code to work on jupyter notebooks, but I can't figure out an automatic way to get the nice .Rmd files I'm used to. I never want to put generated output into version control.

Previously, with normal jupyter notebook, I used jupytext to make nice files for version control. I added two lines to my jupyter config:

c.NotebookApp.contents_manager_class="jupytext.TextFileContentsManager"
c.ContentsManager.default_jupytext_formats = ".ipynb,.Rmd"

and everything magically works. The output and all the nasty json gets saved in the .ipynb file, which I .gitignore, while a human readable (and sanely version controllable) .Rmd file gets created automatically. I'd like this inside VS Code.

Aside: I tried, just as a workaround, to use a "run on save" extension in VS Code, in order to automatically convert my .ipynb every time I hit "save"... but it looks like the VS Code notebook interface isn't firing the right events for "run on save" extensions to work right (microsoft/vscode#130799). The extensions can't detect that a save occurred.

Is there any way to do this with VS Code, even with workarounds?

Let's track in upstream issue microsoft/vscode#124551
