Creating a Task Manager Application with Ruby


A task manager application allows users to create, update, and organize their tasks or to-do lists. In this guide, we'll walk through the process of creating a simple task manager application using Ruby. This project will help you grasp the fundamentals of application development, including data management and user interfaces.


Before you start, make sure you have the following prerequisites:

  • Basic knowledge of the Ruby programming language
  • A code editor (e.g., Visual Studio Code, Sublime Text)
  • Understanding of data structures (arrays or hashes)

Step 1: Data Storage

To manage tasks, you'll need a data structure to store them. In this example, we'll use a simple array to store tasks. You can choose to implement a database for more advanced applications.

# Initialize an empty array to store tasks
tasks = []

Step 2: Adding Tasks

Create a method to add tasks to the list. Users can input task names, and the tasks are stored in the array.

def add_task(task_list, task)
task_list << task
# Example usage
add_task(tasks, 'Buy groceries')

Step 3: Displaying Tasks

Create a method to display tasks from the list. You can format the output for a more user-friendly presentation.

def display_tasks(task_list)
task_list.each_with_index do |task, index|
puts "#{index + 1}. #{task}"
# Example usage

Step 4: Marking Tasks as Done

Extend your application by allowing users to mark tasks as done. You can use a hash to track the status of each task.

def mark_task_as_done(task_list, task_index)
task_list[task_index] = "[DONE] #{task_list[task_index]}"
# Example usage
mark_task_as_done(tasks, 0)


Creating a task manager application in Ruby is a great way to learn about data management, user interaction, and application logic. As you progress, you can add more features, such as task due dates, priority levels, and reminders.

This project is just the beginning of your journey into application development with Ruby. It's a practical stepping stone for more advanced projects and real-world applications.

Enjoy building your task manager application with Ruby, and use it to stay organized and productive!
