basic-git-rust

This is a very basic and partial rust implementation of git.

The goal of this project is to get better at rust programming, not to make a full featured git implementation.

I've already done a few rust projects (with WebAssembly or bevy), however, I wanted something that needs to deal directly with:

• I/O
• parsing
• handling bytes
• parallelism

This is a work in progress, we'll see where it goes.

Setup

Add the following alias to your .zshrc / .bashrc, it will:

• lets you use the basic-rust-git implementation from anywhere by using the alias mygit
• it runs

alias mygit=/path/to/your/repo/mygit.sh

Utilities

If you cloned the repository from github, the git objects (commits, tree, ...) will be packed into .git/objects/pack and not present in .git/objects as individual objects.

Run the following to unpack the objects:

./unpack.sh

Features

The features won't be implemented in full.

For the moment, the commands don't handle packed objects, so you may need to run ./unpack.sh on the repo if you just cloned it if you want to run commands against it.

mygit cat-file

git cat-file - doc reference

mygit cat-file -p 342293066bfc04c621eb7cbe4d5fc3a272ff0b05

Genesis of the project

It started with the "Build Your Own Git" Challenge from code codecrafters.io, after the first two steps, it requires a 40$/months membership - it's a little too much for the usage I would have had.
