(Julia version of #1651)

knitr will soon support Julia chunks with JuliaCall package. I don't have strong opinion on the support for Julia, but it would be useful if we can use Julia in RStudio seamlessly as well as Python.

strongly second this. Julia is going to be incredibly important to the numerical computing community in years to come, and already has a vibrant, friendly community. would be great to be able to work in Rmd with seamless exchange between R and Julia, and be able to seamlessly import julia functions into R scripts a la reticulate and python.

Julia is pretty powerful in AIOT era, programming like Python and running like C.
Wish RStudio can support Julia code intelligence.
Julia is good at optimization problem. JuMP eco-system is pretty mature like Stan in R and Tensorflow in Python.

Doesn't RStudio use Ace for syntax highlighting? I'm pretty sure they already have syntax highlighting for Julia. Even that would be nice.

This doesn't appear to be a high priority RStudio team at the moment so people might want to look to https://github.com/julia-vscode/julia-vscode instead.

How hard would it be to code an add-in to RStudio that adds Julia syntax highlighting ? (I genuinely don't know, if someone points me in the right direction I'm happy to give it a try)

I also want to see support for Julia in RStudio.
Two things I want to be able to do are:

julia_chunk

  1. I want to see the Julia variables created in code chunks in the Global Environment on the top right of RStudio (same as R and Python show).

  2. When using code chunks in a R notebook, I want to be able to run one line of code at a time inside the Julia chunk (right now ctrl+enter runs the whole chunk)

We could probably use https://github.com/stefan-m-lenz/JuliaConnectoR to support this. We could even rely on a knitr engine implementation using that package.
