Since the good old ob-julia is now orphaned, there was no real support for Julia within org-mode these days. I tried to fill this gap with a very light and simple Emacs package based on ESS: ob-ess-julia. It’s still at an early stage of development, which means “clearly incomplete and probably buggy” However, most of usual basic tasks should be okay at this stage.
I would be glad if some experimented {Emacs + Julia} users could give it a try using the example file, and make bug reports if needed (in particular Windows users, since the package is almost untested on Windows).
FYI, in case anyone is looking for something a bit more stable, there’s https://github.com/nnicandro/emacs-jupyter which is a very well made and mature Org mode environment for Jupyter, so you can run julia code in it by just installing the IJulia.jl jupyter kernel.
I don’t mean this to discourage your work on ob-ess-julia, just putting it out for informational purposes. It’s good to see projects for this that aren’t reliant on Jupyter.
