🧠 Wyag — The Stupidest Content Tracker

Wyag is a Git-like version control system built from scratch in Python.
The name stands for Write Yourself A Git, inspired by the idea of learning by building.

🚀 “The best way to understand Git is to build Git.”

💡 Why I Built This

I built Wyag to understand how Git works under the hood. By re-creating Git’s core concepts — blobs, trees, commits, refs — I gained a deeper understanding of version control, file storage, and DAG-based history.

This project helped me master:

• Git internals
• File systems and binary formats
• Hashing and data integrity
• Python I/O and CLI design

🌱 What’s Next

• Commit graph visualization
• Branching and merging
• Web frontend for viewing repo state
• Improved diff and patching
