any equivalent for Julia?

[ArcticSnow]

Hi,

I was wondering if you'd know an equivalent extension to write .jl (julia) file directly from the Jupyterlab editor? If not, is there a possibility to add support for Julia file from this extension?

Thanks

[jtpio]

Not that I know of.

But it should be possible to create a similar extension to this one to create Julia files. Or a more generic one to create any type of files.

Hi @jtpio !
So I forked your project and made an attempt to adapt the code to create .jl files instead of .py. I get an error message during the npm run build. Would you have a look at my modification and edits if needed? This is my first time messing with code for a Jupyterlab extension.

Thanks

That's awesome @ArcticSnow !

The code looks good. Would you mind posting the error you get from npm run build?

Usually it's good practice to create a new conda environment locally for development:

conda create -n jupyterlab-python-file -c conda-forge jupyterlab nodejs
conda activate jupyterlab-python-file
npm install
npm run build
jupyter labextension install .

[ArcticSnow]

Ok, I tried as you indicated creating a conda VE and run npm, though npm still returns the following error.

Wow, good catch.

There must have been a new version of the ui-components package that breaks compatibility with the previous tsconfig.

What if you apply the following change to tsconfig.json? (I'll push the same to this repo)

diff --git a/tsconfig.json b/tsconfig.json
index 4946663..3227f68 100644

[jtpio]

Should be fixed in: #9

[ArcticSnow]

Wow thanks for the guidance, everything works now!!!
I'll update the readme and media (logos) and then I'll have to figure out how to make the extension available to others :)

[jtpio]

Nice!

To make it available to others, the easiest would be to publish it to npm.

There is a section about this in the JupyterLab documentation: https://jupyterlab.readthedocs.io/en/latest/developer/extension_tutorial.html#publish-your-extension-to-npmjs-org

[ArcticSnow]

Well it is now published on npm following their tutorial.
To install it:

jupyter labextension install @arcticsnow/jupyterlab-julia-file

I simply miss the Julia icon. But most importantly it works as wanted. :)
many thanks!

[jtpio]

Well done!

You might want to have a look at this example to add an icon to the launcher: https://github.com/jtpio/jupyterlab-extension-examples/tree/master/launcher

The same repo contains more examples on various other topics related to JupyterLab extension development, in case you are interested.

[jtpio]

Closing as answered.

Would you like to open a PR to add a link to your extension in a new "Related Projects" section in the README file?
