Testing Jupytext Markdown Without Updating

[saulshanabrook]

Hey! I was curious if it is possible to execute a notebook without updating it? I am trying to test execute some markdown jupytext documents, but I don't want it to save the changes. It was updating the jupytext_version and adding the kernel name to the code cells.

Hey @saulshanabrook , thanks for the interesting question!

I guess you've not clicked on "Save" in Jupyter, right ?
So maybe what is happening is that you have the autosave activated in Jupyter.
In the documentation we have a few hints on how to deactivate the autosave in this Q&A.

Let me know if that helps (and if you think we should add this to the FAQ). Thanks!

Hey @mwouts! I meant via the CLI, sorry, I wasn't clear here, like jupytext --execute notebook.md.

Oh I see... Well I would have suggested then to use

cat notebook.md | jupytext --execute

but at the moment (jupytext==1.13.6) that does not work (I'll try to fix that with the next release, please leave this issue open).

Meanwhile you might want to use something like this?

cat test.md | jupytext --to ipynb | jupyter nbconvert --execute --stdin --to html --stdout

Also I'd like to double check with you what you want to achieve by executing the .md notebook - do I understand correctly that it is a standalone text notebook? Are you interested in the ipynb notebook with output cells or you just want the result of executing the notebook in e.g. files generated by the notebook?
