dynamic_constants_via_const_set

📦 Dynamic Namespacing with const_set and const_get

Use Module#const_set and Module#const_get to define or retrieve constants at runtime, enabling powerful DSLs and plugin architectures. This allows you to map external configurations or directory structures into Ruby modules and classes on the fly.

module PluginLoader
  PLUGIN_DIR = "plugins"

  def self.load_plugins
    Dir["#{PLUGIN_DIR}/*.rb"].each do |file|
      plugin_name = File.basename(file, ".rb").split("_").map(&:capitalize).join
      require_relative file
      # e.g., PluginLoader::UserAuth -> UserAuth class defined in file
      const_set(plugin_name, const_get("PluginLoader::#{plugin_name}"))
    end
  end
end

PluginLoader.load_plugins
puts PluginLoader::UserAuth.new.authenticate
