A Beginner's Guide to Ruby Metaprogramming: Using Simple Examples and Tips to Enhance Your Code

Metaprogramming is a technique that allows you to write code that generates other code at runtime. This is done by using Ruby's reflection capabilities to introspect on classes and objects, and then using this information to dynamically generate new code. This can be a powerful way to write more flexible, reusable, and maintainable code. Metaprogramming in Ruby can be divided into two categories: class-level and object-level metaprogramming. Class-level metaprogramming involves adding, removing, or modifying methods and other behavior at the class level. Object-level metaprogramming involves adding, removing, or modifying behavior at the instance level. Read more
