Julia: Add variable sharing

[ShalokShalom]

Hi there :)

I would be interested to add a new language.

From the looks of it, it seems pretty doable, and I am still confused, as to why some of the languages are implemented in this repo, and some, like Python seem to be difficult to locate at all, and Javascript has its own location? altogether.

The most insightful information I could find, was the FAQ.

Still, I welcome a little more details, as to how I could add Julia.
It runs mostly in a JIT, that evaluates LLVM code, if that is any helpful.

Julia should already work, though we're obviously missing documentation for it.

.NET Interactive's Python and R support are via the Jupyter protocol, so other languages that have dedicated Jupyter kernels can work via those kernels.

If you try it, we'd be curious to know if you run into issues.

Oh wow.

I am way too sleepy now, but I am going to look into this tomorrow. Wonderful day 🌞

Yes, Polyglot kernel can connect to IJulia using the Jupyter support. However, Jupyter protocol does not support variable sharing so that will need to be added custom. Here are the instructions on how you can add that for the Jupyter sub-kernel: https://github.com/dotnet/interactive/blob/main/docs/adding-jupyter-kernels.md

IJulia does support Jupyter comms message so it can be added.

Thanks a lot. That is a very helpful guidance.
I will add a PR to the README, that links to that documentation.

I'll make some docs updates and leave this issue open as the updated title reflects something that hasn't been done. There isn't currently support for Julia variable sharing. We'd happily help with a PR if anyone is feeling motivated to contribute.
