Julia course: from total beginner to power user

This repository is a collection of resources to teach everything about the Julia programming language.

These resources are used in the Julia: from total beginner to power user Youtube playlist.

Direct links to the notebooks

You can use the notebooks either by using the direct links provided here, or by downloading/cloning the repository (see below).

To use the direct link, open julia, then type using Pluto, and execute the line of code provided below. If you need to install Pluto first, see below.

1. Variables and basic types in Julia

   

   Pluto.run(notebook = "https://raw.githubusercontent.com/VEZY/julia_course/main/1-variables_and_basic_types.jl")

2. Arrays

   

   Pluto.run(notebook = "https://raw.githubusercontent.com/VEZY/julia_course/main/2-arrays.jl")

3. Tuples

   

   Pluto.run(notebook = "https://raw.githubusercontent.com/VEZY/julia_course/main/3-tuples.jl")

4. Dictionaries

   

   Pluto.run(notebook = "https://raw.githubusercontent.com/VEZY/julia_course/main/4-dictionnaries.jl")

Usage

Pluto

Most of the resources are Pluto reactive notebooks. You know when a julia script (a .jl file) is a notebook when it starts with "### A Pluto.jl notebook ###". In this case, use Pluto to execute the file.

Install Pluto

To install Pluto, enter the package manager mode in Julia by pressing ] in the REPL, and then execute the following code:

add Pluto

Then, each time you want to use Pluto, type the following command in the REPL (in julia mode):

using Pluto

Open a notebook

There are different ways to open a notebook, but it's always using the same function: Pluto.run().

The most simple way is to just run it:

using Pluto
Pluto.run()

Then you'll have to navigate manually to your notebook.

A second way is to open a notebook by passing its path, e.g.:

Pluto.run(notebook = "1-variables_and_basic_types.jl")

And a third way is by using a notebook directly from the internet by passing its link, e.g.:

Pluto.run(notebook = "https://raw.githubusercontent.com/VEZY/julia_course/main/1-variables_and_basic_types.jl")

Watch this video if you need more details about how to use Pluto.

Download and instantiate

If you want to use the resources from this repository locally, the best way is to download a local copy (or clone it if you know GIT). To do so, click on the green button in this page called "Code":

And choose "Download ZIP":

Then, unzip the file, and open the directory in VS Code, or just open Julia in this repository.

Finally, enter the package manager mode in Julia by pressing ] in the REPL and run the following command:

activate .
instantiate

It will first activate the project, and then instantiate it, i.e download all packages used for this project.

The resources are numbered, and their titles correspond to the Youtube videos they relate to.
