The Ruby Programming Language

The Ruby Programming Language is the authoritative guide to Ruby 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 programming language "bibles" (including JavaScript: 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.

David Flanagan is a computer programmer who spends most of his time writing about JavaScript and Java. His books with O'Reilly include JavaScript: The Definitive Guide, JavaScript Pocket Reference, Java in a Nutshell, Java Examples in a Nutshell, and Java Foundation Classes in a Nutshell. David has a degree in computer science and engineering from the Massachusetts Institute of Technology. He lives with his wife and children in the U.S. Pacific Northwest bewteen the cities of Seattle, Washington and Vancouver, British Columbia. David has a blog at www.davidflanagan.com.

Yukihiro Matsumoto ("Matz"), the creator of Ruby, is a professional programmer who worked for the Japanese open source company, netlab.jp. Matz is also known as one of the open source evangelists in Japan. He's released several open source products, including cmail, the emacs-based mail user agent, written entirely in emacs lisp. Ruby is his first piece of software that has become known outside of Japan.
