Product Description

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.

Customer Reviews

Exactly what I expected from O'Reilly
I wish every book about a programming language was written like this one:

First, it is fairly compact and doesn't waste space (and your time) explaining to you what is a byte or a register, like some 800 page "volumes about everything" do. It correctly assumes that the reader is a programmer and explains the language, not the programming.

Second, it covers Ruby in depth. Read this book and you'll easily understand the most craziest Ruby code examples that could be found inside of Rails and other popular libraries. Moreover, I've found a few tricks in the book that I don't believe I saw in the wild.

And finally, author's language is very clean, free of buzzwords and needless repetitions. As always with O'Reilly books, this one is also very neatly structured and makes an excellent reference book.

Buy it.

Makes Dave Thomas look bad... Well... Worse than he normally does.
Very, very dense reading, but very complete as well. Aspects of the language that were only glanced over (or even ignored entirely) by the "pickaxe" book are covered in great detail. The only downside is that you have to look at several of those horrible high school notebook doodles the wannabe Murakami "Why" produces whenever people convince him that he's either "clever" or "talented."

Worthy of comparison to K&R
This is well written, well organized, and covers the whole core language. It isn't a cookbook, and it isn't an API reference, but for what it is, it's excellent.

The organization makes sense, the index is usable, and the writing is precise enough to leave no ambiguity.

My only complaint would be too much space spent on differences between 1.8.6 and 1.9, and too much attention to text encodings.
