jupytext-config and foreign kernels / extensions

[parmentelat]

now that #1163 is giving us an ability to easily create exotic formats like bash or javascript notebooks,
I notice that I cannot open them by double-clicking, because I don't know the string to use in jupytext-config

specifically I have tried
jupytext-config set-default-viewer bash sh javascript js

meaning that I now have

$ jupytext-config list-default-viewer
python: Jupytext Notebook
markdown: Jupytext Notebook
myst: Jupytext Notebook
r-markdown: Jupytext Notebook
quarto: Jupytext Notebook
julia: Jupytext Notebook
r: Jupytext Notebook
bash: Jupytext Notebook
sh: Jupytext Notebook
javascript: Jupytext Notebook
js: Jupytext Notebook

but to no avail in either case...

When you say "open them by double-clicking", you mean you were trying to open them as text notebooks? If so, I can without any issues.

And I dont have any special jupytext config.

[parmentelat]

since these documents are notebooks, I would like a double-click in the file browser to open them .. as notebooks, and not as text files

so for .md and .py files, this is possible using

jupytext-config set-default-viewer

which by default defines "Jupyter Notebook" as the default factory for viewing a predefined set of file types

it is possible, like I do in the OP, to add other file types, that will also be bound to "Jupyter Notebook" as the default viewer
except that I don't know how to describe the "right" filetype for these 2 cases (js and bash), and I expect the issue would be the same for any foreign kernel indeed...

Hey @parmentelat , that's a good question. I am afraid I don't know the answer. Given that the setting UI says that the available file types are

text notebook directory markdown PDF python json julia csv tsv r
yaml svg tiff jpeg gif png bmp webp html vega5 vega-lite5 vega-lite4
vega-lite3 plotly jupyterlab-workspace myst r-markdown quarto

I did try text and notebook but that did not help in opening a .sh notebook as a notebook with a single click.

hi @mwouts
thanks for your input
something I'll try to ask to the jlab gurus if I get a chance ;-)
