Quarto: Running a Julia notebook

This is based on the Quarto Julia docs.

Setup

1. Install Julia for your operating system.

2. Install IJulia. For this step, I use the Julia REPL. Enter pkg mode by pressing ] and enter: add IJulia. This installs the IJulia kernel into the .julia directory in your home directory.

3. From the Julia REPL, start a notebook server and kernel:

using IJulia
notebook()

or alternatively install the Julia extension for VS Code.

Usage

4. Create a new markdown file with the following front matter. The key item to include is jupyter: and the kernel to be used:

---
title: "Quarto - Julia notebook"
format: html
jupyter: julia-1.8
---

5. From the command line, run quarto preview to start the preview server or Render in VS Code.

import Pkg; Pkg.add("Plots")

Parametric Plots

Plot function pair (x(u), y(u)). See Figure 1 for an example.

using Plots

plot(sin, 
     x->sin(2x), 
     0, 
     2π, 
     leg=false, 
     fill=(0,:lavender))

See Figure 2 for another example.

using Plots

plot(sin, 
     x->sin(4x), 
     0, 
     2π, 
     leg=false, 
     fill=(0,:pink))

Figure 2: Sin Plots

You should now see rendered charts with Julia.

VS Code

Here’s a rendering of the Julia document in VS Code.
