Metaprogramming in Ruby - Lesson 1

This course is intended for people who already understand how to write basic Ruby code, and who want to improve their English skills while starting to use metaprogramming. As the textbook, we will use Metaprogramming Ruby, which provides a good introduction to metaprogramming in a conversational fashion.

Class Size: Limited to four students

Requirements:

• You have written a simple program in Ruby before


• A laptop with Ruby installed on it


• A copy of Metaprogramming Ruby (available as hardcopy from amazon.co.jp or ebook at the pragmatic bookshelf).

 

First Lesson

We will cover material from Chapter 1, Monday: The Object Model, from Metaprogramming Ruby.

During the first lesson, we should cover:

Open Classes: In Ruby, you can modify a class after you declare it.  When you should you use this power and when does it cause problems.

The Truth About Classes: In Ruby, classes are objects. We will cover some of the uses and implications of this.

We are still searching for the best way to combine English and Ruby learning. This lesson will be a trial run, and if there is sufficient interest, we will continue with future lessons.
