MiniGitWithCpp

This is a C++ implementation of a minimal Git-like version control system.

Overview

MiniGitWithCpp is a simplified Git implementation written in C++ that demonstrates core Git concepts including:

• Object storage (blob, tree, commit)
• Delta compression
• Pack file handling
• Basic Git operations (init, add, commit, clone)

Features

• Object Model: Implements Git's object model with blob, tree, and commit objects
• Delta Compression: Supports Git's delta compression for efficient storage
• Pack Files: Handles Git pack files for network transfer optimization
• HTTP Protocol: Implements Git's smart HTTP protocol for cloning
• Testing: Comprehensive unit tests using Google Test framework

Building

mkdir build
cd build
cmake ..
make

Usage

# Initialize a repository
./git init

# Hash a file
./git hash-object <file>

# Write tree
./git write-tree

# Commit
./git commit-tree <tree-sha> -m "commit message"

# Clone from remote
./git clone <url> <directory>

Testing

cd build
ctest

Requirements

• C++20 compiler
• CMake 3.13+
• zlib
• OpenSSL
• libcurl
• Google Test (auto-downloaded if not present)
