7. 'Hello World' on main

In this chapter, we are going to use the basic git workflow by writing a simple program with a team.

	A fairytale is a story in which anything can happen

7.1 Exercise 1

On Codeberg, create a new repository.

	Easy peasy!

7.2 Adding Collaborators

	A Collaborator is someone in your team

To add Collaborators, in your repo, click on 'Settings' (at the top right), then click on the 'Collaborators' tab.

Add one or more Collaborators. Collaborators are people you work together with. They too can now modify the code.

7.3 Exercise 2

Add at least 1 Collaborator.

	Add me, I am the best!

7.4 Clone the repo

	You already know this

Clone the repository on your computer:

git clone [repo_url]

For example,

git clone https://codeberg.org/richelbilderbeek/iloverichel

7.5 Exercise 3

Clone your repo

7.6 Processing

Start Processing.

Below is a short Processing program:

void draw() 
{

}

You can run it by clicking on 'Run'.

7.7 Exercise 4

• Save the Processing program above in the folder of your repository
• Upload it

7.8 Modifying code

Navigate into the folder of your repository:

cd [repo_name]

For example,

cd iloverichel

Here, as usual, you can do add, commit, push and pull:

git add .
git commit -m "Improve"
git push
git pull

With Processing, you can edit the code.

7.9 Exercise 3

Make something pretty together!

Each team member must

• add one line of code at a time
• add, commit and push it
• at least 5 commits per team member

Below is some example code:

void setup()
{
  size(256,256);  
}

void draw() 
{
  fill(mouseX, mouseY, mouseX + mouseY);
  ellipse(mouseX, mouseY, 50, 50);  
  fill(mouseY, mouseX, 255);
  ellipse(mouseY, mouseX, 50, 50);  
}
