Jupytext & SOS kernel issue

[thomaspernet]

Jupytext works fine with Python/R kernel but converts code cells into markdown cells when using the SOS kernel.

cf the image below. It is a code cell. After saving the notebook and restart it, it converted the code cell into markdown

Hello @thomaspernet , thanks for reporting this.
Maybe this is because the SOS kernel is not supported yet?

Anyway I'd be interested in adding it... Could you please provide a short Jupyter notebook with that kernel, and if possible, an example that reproduces the issue you encounter here?
Note that, if you like, you can contribute the example notebook in a PR, following these instructions.

Thanks

Dear @mwouts
thanks for your reply. Here is the link to download a reproducible notebook. I added the steps in the notebook with the link to install SOS-Kernel.

I hope it won't take too much of your time, or too complicated to add another Kernel..

Thanks!

Thank you @thomaspernet for the notebook, that is very helpful!

I have added the SoS language in the add_sos branch, would you like to give it a try, and confirm that it works now? You can install the development version with

pip install git+https://github.com/mwouts/jupytext.git@add_sos

(dont forget to restart your notebook server before testing).
