How can we write classes that are easy to understand? How can we write Ruby in a declarative way? How can we use metaprogramming without introducing chaos? Come learn the magic behind the first bit of metaprogramming we all encounter with Ruby - attr_reader. From there, we can learn how different gems use class macros to simplify our code. Finally, we’ll explore multiple ways we can make our own class macros to make our codebase easier to read and extend.
