git-from-scratch

A lightweight C implementation of a Git-like version control system for text files.
This project is a learning-oriented reimplementation of core Git features to understand how Git works under the hood.

---

🚀 Current Progress

You can compile the project and run your own mygit command:

# Compile
gcc main.c -o mygit

# Use it like git
./mygit <command>

✅ Supported Commands

1. mygit init

Initializes a new repository in the current directory. It creates the following structure:

.git/
 ├── objects/
 ├── refs/
 └── HEAD

2. mygit cat-file

Used to inspect the content of a commit object. You can view details such as:

Author

Parent commit

Commit message

🛠 Purpose

This project is not a full Git replacement, but rather an educational implementation to:

• Explore how Git manages objects (blobs, trees, commits).

• Understand hashing, object storage, and repository internals.

• Gain deeper insights into version control concepts.

📂 Repository Structure

├── src

└── (more files to come...)

🔧 Requirements

• GCC (tested with GCC 12.3.0 on Ubuntu 24.04 LTS)
• Any C compiler supporting C11 or later should also work
• Linux/macOS environment (Windows may work under WSL)

How to Compiler

• gcc main.c -o mygit -lcrypto -lz
  • lz = tells comiler to link zlib library
  • lcrypto = tells comiler to link openssl library
• zlib library compress file content plain text
• openssl library for hashing the file content.
