Is this change enabled by an enhancement to JupyterLite? Could you please add some context links? 🙇

[martinRenou]

David is looking into making the Python API work in JupyterLite 🚀

Making good progress this week! You can give it a try here https://davidbrochart.github.io/jupytergis-demo (note not everything is working yet)

It is built from https://github.com/davidbrochart/jupytergis-demo

Once we have something stable, we should update our JupyterLite deployment with what David has there. Probably as part of this PR here?

[davidbrochart]

Yes, there are other changes that will make jupytergis_lab work in JupyterLite, currently in my branch.
The piece that allows a Python kernel to access a shared document, and the corresponding file, is my-jupyter-shared-drive: a collaborative drive that is actually not shared with anybody (it just allows to go through the underlying CRDTs to access data).

[martinRenou]

Thanks!! I have some suggestions

[davidbrochart]

Thanks @martinRenou.
The Read the Docs build fails but I don't know why: https://readthedocs.org/api/v2/build/27080482.txt.

Oh I see:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
sphinx-togglebutton 0.3.2 requires setuptools, which is not installed.
sphinx-togglebutton 0.3.2 requires wheel, which is not installed.
sphinx-autodoc-typehints 3.0.1 requires sphinx>=8.1.3, but you have sphinx 7.4.7 which is incompatible.
sphinx-tabs 3.4.1 requires docutils~=0.18.0, but you have docutils 0.21.2 which is incompatible.

Now the error is:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
sphinx-autodoc-typehints 3.0.1 requires sphinx>=8.1.3, but you have sphinx 7.4.7 which is incompatible.
sphinx-tabs 3.4.1 requires docutils~=0.18.0, but you have docutils 0.21.2 which is incompatible.

The JupyterLite deployment here seems to have the collaborative drive, but I suspect running the Notebook.ipynb doesn't work because of #425?

Yes, it works with 7dc7400.
So we should think about kernel vs Jupyter paths now.

Rebased from the UI

[martinRenou]

I just pushed two new commits (+ the linter one)

• Show an error dialog in the front-end if no collaborative drive is there 946e34d this comes as a replacement for the old import error we were showing in Python
• Handle file operations from the front-end instead of in Python 8181441

This works only with QuantStack/yjs-widgets#22

Case 1: Open an existing file (path is relative to the current context aka Notebook)

Uploading Screencast From 2025-02-06 18-25-05.mp4…

Upload doesn't work, but hey it's working

Case 2: Open a non-existing file, we create it (path is relative to the current context aka Notebook)

Screencast.From.2025-02-06.18-21-38.mp4

Case 3: Open without passing a file path, we don't create anything

Looks like we're hitting flaky visual regression test, let's go ahead with this!!

Thanks David
