Jupyter and Julia

See https://datatofish.com/add-julia-to-jupyter/

Make sure you have julia installed. On Mac, I used:

brew install --cask julia

Then, make sure you install the kernel.

julia -e 'using Pkg; Pkg.add("IJulia")'

In the kernel section here, you have use a name consistent with your julia version.

(setq org-babel-default-header-args:jupyter-julia '((:async . "no")
                                                    (:session . "jupyter-julia")
                                                    (:kernel . "julia-1.8")
						    (:results . "value")
						    (:exports . "both")
						    (:eval . "never-export")))

(require 'jupyter)
(require 'ob-jupyter)

print("Hello World")

here is a fun ascii plot.

function mandelbrot(a) 
    z = 0
    for i=1:50
        z = z^2 + a
    end
    return z
end

for y=1.0:-0.05:-1.0
    for x=-2.0:0.0315:0.5
        abs(mandelbrot(complex(x, y))) < 2 ? print(".") : print(" ")
    end
    println()
end

These run asynchronously, be patient!

you have to install Plots if you don’t have it.

import Pkg; Pkg.add("Plots")

using Plots
x = 1:10; y = rand(10); # These are the plotting data
plot(x, y)

And, an entertaining function with emojis. This is a factorial function with recursion.

function 😎(🤓)
    if 🤓 == 0
        return 1
    else
        return 🤓 * 😎(🤓 - 1)
    end
end
