"An under-the-hood look at how the Ruby programming language runs code. Extensively illustrated with complete explanations and hands-on experiments. Covers Ruby 2.x"--;Tokenization and Parsing -- Compilation -- How Ruby Executes Your Code -- Control Structures and Method Dispatch -- Objects and Classes -- Method Lookup and Constant Lookup -- The Hash Table : The Workhorse of Ruby Internals -- How Ruby Borrowed a Decades-Old Idea from Lisp -- Metaprogramming -- JRuby : Ruby on the JVM -- Garbage Collection Basics in Rubinius and MRI -- Conclusion.;"Ruby is a powerful programming language with a focus on simplicity, but beneath its elegant syntax, the language is performing countless unseen tasks. Ruby Under a Microscope gives developers an inside, hands-on look at Ruby's core, using simple diagrams coupled with clear explanations. Author Pat Shaughnessy takes a scientific approach, laying out a series of experiments with Ruby code to demonstrate how things work. Shaughnessy's lucid illustrations will serve as a guide for developers writing Ruby programs. Developers of all stripes will find this a fascinating behind the scenes look at how programming languages work"--
