Book Description

The Language is the authoritative guide to and provides comprehensive coverage of versions 1.8 and 1.9 of the language. It was written (and illustrated!) by an all-star team:

  • David Flanagan, bestselling author of language “bibles” (including : The Definitive Guide and Java in a Nutshell) and committer to the Ruby Subversion repository.
  • Yukihiro “Matz” Matsumoto, creator, designer and lead developer of Ruby and author of Ruby in a Nutshell, which has been expanded and revised to become this book.
  • why the lucky stiff, artist and Ruby programmer extraordinaire.

This book begins with a quick-start tutorial to the language, and then explains the language in detail from the bottom up: from lexical and syntactic structure to datatypes to expressions and statements and on through methods, blocks, lambdas, closures, classes and modules.

The book also includes a long and thorough introduction to the rich API of the Ruby platform, demonstrating — with heavily-commented example code — Ruby’s facilities for text processing, numeric manipulation, collections, input/output, networking, and concurrency. An entire chapter is devoted to Ruby’s metaprogramming capabilities.

The Ruby Programming Language documents the Ruby language definitively but without the formality of a language specification. It is written for experienced programmers who are new to Ruby, and for current Ruby programmers who want to challenge their understanding and increase their mastery of the language.

Book Description

is famous for being easy to learn, but most users only scratch the surface of what it can do. While other books focus on ’s trendier features, The Book of reveals the inner workings of one of the world’s most popular languages, teaching you to write clear, maintainable code.

You’ll start with the basics—types, data structures, and control flows—and progress to advanced features like blocks, mixins, metaclasses, and beyond. Rather than bog you down with a lot of theory, The Book of Ruby takes a hands-on approach and focuses on making you productive from day one. As you follow along, you’ll learn to:

  • Leverage Ruby’s succinct and flexible syntax to maximize your productivity
  • Balance Ruby’s functional, imperative, and features
  • Write self-modifying programs using dynamic techniques
  • Create new fibers and threads to manage independent processes concurrently
  • Catch and recover from execution errors with robust exception handling
  • Develop powerful applications with the framework

Each chapter includes a “Digging Deeper” section that shows you how Ruby works under the hood, so you’ll never be caught off guard by its deceptively simple scoping, multithreading features, or precedence rules.

Whether you’re new to programming or just new Ruby, The Book of Ruby is your guide to rapid, real-world software with this unique and elegant language.
