macro_with_included_hook

🔁 Building macros via included callback

Define class macros by intercepting self.included in modules, injecting class methods, and managing inheritance cleanly.

module ActsAsTaggable
  def self.included(base)
    base.extend ClassMethods
  end

  module ClassMethods
    def acts_as_taggable
      has_many :tags
    end
  end
end

class Post
  include ActsAsTaggable
  acts_as_taggable
end
