💎 Metaprogramming in TuskLang - Ruby Edition

"We don't bow to any king" - Dynamic Code Generation with Ruby Magic

Metaprogramming in TuskLang provides powerful dynamic code generation capabilities, allowing you to create, modify, and extend Ruby classes and methods at runtime. In Ruby, this integrates seamlessly with Rails, ActiveRecord, and provides advanced metaprogramming patterns that leverage Ruby's dynamic nature.

🎯 Summary

TuskLang's metaprogramming system in Ruby provides:

- Dynamic method creation with runtime code generation - Dynamic class generation for models, services, and controllers - Method missing patterns for flexible method dispatch - Module and concern generation for code organization - ActiveRecord metaprogramming for dynamic associations and callbacks - Controller metaprogramming for dynamic actions and filters - Testing frameworks for metaprogramming validation - Security features for safe dynamic code generation - Custom rake tasks for metaprogramming management

The Ruby implementation maintains TuskLang's rebellious spirit while providing enterprise-grade metaprogramming capabilities that "don't bow to any king" - not even the constraints of traditional static code patterns.
