Go Todo App

This is a simple CLI-based Todo application built in Go. It allows you to manage tasks by adding, marking as complete, viewing, and deleting them. Tasks are saved to a JSON file so they persist between sessions.

Features

• Add tasks with descriptions
• Mark tasks as complete
• Delete tasks with confirmation
• View all tasks or individual tasks by ID
• Persistent storage using a JSON file
• Modular code structure with a task package
• Unit tests for core functionality

Getting Started

Prerequisites

• Go installed on your machine (version 1.18+ recommended)

Installation

1. Clone the repository to your local machine.

2. Initialize the module if not already done:

   go mod init todo-app

3. Usage

   go run main.go

Usage

Upon running the application, a menu will be displayed with options:

1. List all tasks - View all tasks with their completion status.
2. Add a task - Create a new task by providing a description.
3. Mark a task as complete - Set the completion status of a task by entering its ID.
4. View a specific task - Display details of a task by entering its ID.
5. Delete a task - Remove a task by ID, with confirmation.
6. Exit - Quit the application.

File Structure

• main.go - Contains the main program and manu handling
• task/ - Contains the Task struct, functions for managing tasks, and data persistence.
• task/task_test.go - Contains unit tests for task-related functions.

Testing

To run the unit tests for this project:

go test ./task

This will execute tests for the core functionality in the task package, ensuring that adding, completing and deleting tasks works as expected.

Future Enhancements

• Filtering - Add options to filter completed and incomplete tasks.
• API Conversion - Convert the application to a REST API using net/http and gorilla/mux.
• Enhanced Validation - Add checks to prevent adding empty tasks.
