Git-Go

A simple Git implementation written in Go. This project implements core Git functionality including repository initialization, object storage, tree creation, and commit management.

Features

• init: Initialize a new Git repository
• cat-file: Display the contents of a Git object
• hash-object: Compute object ID and optionally creates a blob from a file
• ls-tree: List the contents of a tree object
• write-tree: Create a tree object from the current index
• commit-tree: Create a new commit object
• clone: Clone a remote repository

Prerequisites

• Go 1.22 or later
• Bash shell (for running the provided script)

Installation

1. Clone the repository:

git clone <repository-url>
cd git-go

2. Make the run script executable:

chmod +x run.sh

Usage

./run.sh <command> [arguments...]

./run.sh init

Create and Store a Blob

./run.sh hash-object -w <file>

Display Object Contents

List Tree Contents

./run.sh ls-tree --name-only <sha>

Create a Tree Object

./run.sh write-tree

Create a Commit

./run.sh commit-tree <tree-sha> -p <parent-sha> -m <message>

Clone a Repository

./run.sh clone <repository-url>
