Welcome to the learning_ruby mini-course

Quick start

1. Install Ruby (if you don't have it):

   • On Debian/Ubuntu:

     sudo apt update sudo apt install ruby-full

   • On macOS (homebrew):

     brew install ruby

2. From this folder, run the lesson runner:

   ruby test.rb basics

Replace basics with control_flow or collections to run other lessons.

Run the automated test (requires minitest, included with stdlib):

ruby -I./tests tests/test_basics.rb

Files added

• lessons/01_basics.rb — language basics and small API used by tests
• lessons/02_control_flow.rb — control flow examples
• lessons/03_collections.rb — arrays, hashes, and iterators
• tests/test_basics.rb — a tiny minitest that verifies the basics
• test.rb — lesson runner / quick demo

How I verified

• These are plain Ruby files that should run with a standard Ruby interpreter.

Next steps

• Tell me what you want to focus on (web, tests, metaprogramming, Rails, performance), and I'll prepare the next lesson.
