Advanced Ruby Programming: A Deep Dive

Advanced Ruby Programming: Go Beyond the Framework

Ready to finally understand the "magic" behind Ruby and Rails? To move from being a Ruby user to a true Rubyist?

Advanced Ruby Programming is a comprehensive deep dive into the core of the Ruby language, designed for developers who are ready to master their primary tool. This book is about pulling back the curtain, replacing magic with knowledge, and exploring the "why" that underpins the "how."

You won't just learn what the language does; you'll learn how it thinks.

What You'll Learn:

• Deconstruct the Object Model: Go far beyond class and def. Truly understand the ancestor chain, self, and the elegant power of Singleton Classes.
• Master Metaprogramming: Write code that writes code. Learn the secrets behind Rails' "magic" with define_method, method_missing, and how to build your own expressive DSLs.
• Wield Functional Techniques: Become an expert in Enumerable and the subtle but critical differences between Blocks, Procs, and Lambdas.
• Unravel Concurrency & Parallelism: Get the complete story on the GVL, Threads, and how to achieve true parallelism for CPU-bound work with Ruby 3's Ractors.
• Profile and Optimize: Learn to use professional tools like stackprof and memory_profiler to find bottlenecks and write high-performance, memory-efficient code.
• Craft and Publish Gems: Complete your journey from consumer to producer. Learn the entire lifecycle of building, versioning, and publishing your own gem to the world.

This book is for you if:

• You are an intermediate Ruby developer who feels you've hit a plateau.
• You are a Rails developer who wants to understand the core language that powers your framework.
• You want to write more powerful, flexible, and efficient libraries.
• You are preparing for senior-level Ruby interviews and need to demonstrate deep language knowledge.

This is not a book for absolute beginners. It assumes you are already comfortable with basic Ruby syntax and concepts.
