📚 MyGit Technical Wiki

Welcome to the MyGit technical documentation. This project aims to serve as both a deep dive into how version control systems like Git work under the hood and as a demonstration of low-level systems engineering, cross-language communication, and full-stack VCS architecture.

🧠 Why This Project Exists

Modern developers use Git daily — yet few understand what happens beyond a git commit. This project is built to demystify version control by implementing one from scratch.

MyGit is not just a tool — it's a systems-level learning platform to:

  • Explore internals of source control (Git-style hashing, object storage, DAGs).
  • Practice building performant backend systems in C.
  • Develop frontend UIs using Python + PyQt.
  • Master inter-language linking (via shared libraries).
  • Understand file diffing, patching, indexing, and content addressing.
  • Explore distributed backup systems (via Google Drive integration).

This project sits at the intersection of developer tooling, systems programming, and UI/UX design.

🎯 Project Objectives

  • ✅ Build a Git-inspired VCS from scratch
  • ✅ Modularize the system into CLI and GUI
  • ✅ Learn internals of commit trees, branches, and diffs
  • ✅ Enable communication between compiled C binaries and Python UIs
  • ✅ Explore how to sync repositories with external cloud systems
  • ✅ Build a case-study worthy OSS portfolio project

🛠️ Architecture Overview

🔧 Core (C)

Handles the heavy lifting:

  • Object creation (blobs, trees, commits)
  • SHA-1 or custom hash engine
  • Index management
  • Repository structure setup
  • Branching and tagging logic
  • Diff engine (line/byte level)

🧩 GUI Layer (Python + PyQt)

Provides the interface:

  • Repo initialization and loading
  • Commit message editor
  • File change panel (staged/unstaged)
  • Commit history with graph
  • Branch switching
  • Responsive dark theme UI

🔁 Integration Layer

Bridges the gap between C backend and Python frontend using:

  • ctypes
  • or PyBind11
  • or future-ready RPC/message queue (planned)

📈 Learnings & Takeaways

🔍 Technical Deep Dives

  • File system structures for content-addressable storage
  • Hashing strategies and collision avoidance
  • DAGs for commit history
  • Performance implications of diff algorithms
  • Build systems for cross-platform C code
  • Error handling across language boundaries

🤹 Skills Gained

  • Low-level programming (C)
  • GUI architecture (MVC-style PyQt)
  • Systems design thinking
  • Debugging memory-sensitive VCS logic
  • Virtual filesystem emulation

🌟 What This Project Demonstrates

  • You can build complex tooling from scratch.
  • Language boundaries can be cleanly abstracted.
  • Systems engineering doesn't need to be intimidating.
  • Real tools beat toy projects when building your engineering profile.
  • You can create something Git-like — and understand every byte of it.

📚 Project Wiki Sections

This technical wiki is structured into the following documents:

  • 1. Why This Project? – [Current page]
  • 2. Architecture – Overview of backend/frontend layers
  • 3. CLI Usage – Commands and examples
  • 4. GUI Walkthrough – UI elements and workflows
  • 5. Core Internals – How diff, commit, hash systems work
