Jupytext: How to use Jupytext with Jupyter Lab?

[mwouts]

In the README we describe how to use Jupytext with Jupyter notebook.

For Jupyter Lab we should document

• whether it is possible to edit the notebook metadata
• how scripts and markdown document can be opened as a notebook (requires v0.35, not yet released)
• if it is possible to have two views on a text notebook (notebook and text views, cf. Doug's question )

@grst , would you like to answer these questions? Thanks

whether it is possible to edit the notebook metadata

Only in the text representation. Cf. https://github.com/jupyterlab/jupyterlab/issues/1308.

how scripts and markdown document can be opened as a notebook (requires v0.35, not yet released)

Right click, "Open With" -> "Notebook"

if it is possible to have two views on a text notebook

It is possible to open both a text and notebook version of a notebook, however they do not synchronize.
Clicking on "New View for Notebook" on a text-based notebook is dysfunctional. I do not know what to do to make this work. Maybe the jupyter guys kann tell use more about this.

Thanks @grst . I will soon include this in the README (and ask you to review the change first!).

I wrote an extension that lets you edit metadata in JupyterLab https://github.com/yuvipanda/jupyterlab-nbmetadata. Thought y'all might be interested.

I appreciate all of your efforts in making notebooks work with GIT. I got here because I made a change to notebook and couldn't remember if it was just a spelling correction or a number of changes. As you know, this turned out to be NOT a simple question to answer.

General comment: It could be worth making the installation instructions for Jupiter Lab more distinct e.g. having a link near the top of the markdown for the Jupyter Notebook installation instructions and a link for the Jupyter Lab installation instructions. It may also be worth noting in the instructions that the Jupytext menu won't appear in the File menu for Jupyter Lab.

I know this is minor but there are two distinct installations, which provide two distinct user interfaces.

Very nice work!

Thanks @NoisySignal for the nice feedback. Regarding the documentation, I do agree that the two user interfaces are distinct. Following your remark, I will add a link between the mention of how to pair a notebook to the screenshots of the Jupytext menu in the notebook, and to the commands in Jupyter Lab.
