📝 Terminal TODO App (Built with Go)

A simple command-line TODO list manager written in Go.
Features persistent storage, task completion toggling, deletion, and SHA-256 based change detection.

Built completely from scratch — no external libraries, no AI assistance.

📁 File Format (~/.TODO.txt)

Each TODO item is saved in a |-separated format:

Learn Go concurrency|false
Finish README|true
Refactor the write logic|false

• First column: TODO title
• Second column: Completion status (true or false)

🔐 How Hashing Works

Before saving, the app checks if the in-memory TODO list has changed by hashing it using SHA-256:

data, _ := json.Marshal(T.TODOS)
hash := sha256.Sum256(data)

If the hash differs from the previously loaded state, it writes the updated list to the file. This prevents unnecessary writes and provides a simple "dirty state" check.

🛠️ TODO (Future Features)

• Add CLI flags for quick actions (todo add "Task")
• Export to JSON/CSV
• Color-coded output using fatih/color
• Cobra integration for subcommands
