Building a Simple Object System from Scratch in Ruby
2024-12-15
This blog post details building a basic object system in Ruby without using classes. The author cleverly uses anonymous functions and hash tables to implement core OOP concepts like method lookup, prototypal inheritance, mixins, and metaprogramming. Starting with a constructor function, the post demonstrates simulating private variables and public interfaces, effectively recreating class-like behavior and inheritance. Through clear code examples, readers learn to create objects, define methods, implement inheritance and mixins, and even build a rudimentary `attr_accessor`-like metaprogramming feature. It's a practical guide to understanding object system fundamentals.
