Chapter 8: git branch
git branch
In a while, you will be attempting to make your robot project much much more readable!
But let’s take a break from Python for a moment.
Instead, we’ll with explore more git goodness.
In this chapter, you will be looking at the concept of branches in git.
What is a git branch?
A git branch is just a pointer to your latest commit. Think of the pointer as the tip of a branch.
Each branch has a name (main in the example below). You can rename a branch any time.
You can also trace your commit history on your branch (commits 1, 2, and 3 in the image above).
Multiple branches
You can have multiple branches in your repo, each with its own name.
In the figure above, you have two branches (main and feature).
The main branch points to commit 6, and you can visualise its history of commits (4, 3, 2 and 1).
The feature branch points to commit 8, with a history of commits 7, 5, 3, 2 and 1.
HEAD
You can switch between different branches at any time.
The HEAD pointer tells you which branch you are currently working on.
In the example below, you are currently working on the feature branch.
