I’d like to revisit a discussion that we’ve had a while back already, but today in the context of jlab4
I’m trying to help @mwouts with the jupytext extension for jlab4, and it seems like an alpha version is in sight - https://github.com/mwouts/jupytext/issues/1054 - but at this point there is still the same issue addressed in the post above, namely that double clicking in a jupytext notebook in the file browser opens it in the editor and not as a notebook, and this despite the configuration that says
"markdown": "Jupytext Notebook",
"myst": "Jupytext Notebook",
"r-markdown": "Jupytext Notebook",
"quarto": "Jupytext Notebook",
"julia": "Jupytext Notebook",
"python": "Jupytext Notebook",
"r": "Jupytext Notebook"
is this an expected result of using jlab4 and if so how can we get to enable the desired behaviour ?
here is where i set default viewers in jlab4:
~/ cat .jupyter/lab/user-settings/@jupyterlab/docmanager-extension/plugin.jupyterlab-settings
edit: also available under settings → document manager
Thanks for the tip, it’s helpful to at least know where the config should be located
However I’m still unable to get it to work
I can confirm the new config file gets loaded (after I made a stupid mistake in the json syntax), but I have tried to set the right-hand-side value to
"Jupytext Notebook" because this is what we had before
- and then simply to
"Notebook" because that is what I see in the Open with menu - and it does work fine when I go this road
but none of these settings result in the desired behaviour
could it mean that the jupytext extension should somehow expose a ‘viewer’ thing of some kind ?
the fact that the open-with menu works seems to suggest otherwise, but…
more generally how can I hope to troubleshoot that ?
thanks again for the tip in any case
So the right-click menu works?
I’d try reading this and working through that mp4 example renderer.
It’s not that much code ^^
I am not sure, but i guess the
documentWidgetFactoryOptions in the mp4 renderer example might be the key to what is needed for the viewer to work.
turns out there was a missing field in the widget factory
as a result the ‘Jupytext Notebook’ viewer was not available

it’s all good now, thanks for your help @spookster
