Go Todo CLI App

A simple command-line Todo application written in Go. Todos are stored in a local JSON file.

Features

• Add new todos with a title and description
• List all todos, grouped by incomplete and completed
• Mark todos as completed
• Remove todos by ID
• Data is persisted in todos.json

Usage

Build the app:

go build -o todo

Add a Todo

./todo -action=add -title="Buy milk" -description="Get 2 liters of milk"

List Todos

./todo -action=list

Complete a Todo

./todo -action=complete -id=1

Remove a Todo

./todo -action=remove -id=1

Flags

• -action (add, remove, list, complete) — What you want to do
• -title — Title for the todo (required for add)
• -description — Description for the todo (required for add)
• -id — ID of the todo (required for remove and complete)

Example

./todo -action=add -title="Read Go book" -description="Finish chapter 3"

./todo -action=remove -id=1

Next Improvements
