Aug 07, 2011 Manuel Menezes de Sequeira rated it it was amazing · review of another edition

If you are an experienced programmer wanting to learn Ruby, this book is for you. A word of warning, though: go take a look at Chapter 27, Metaprogramming. That's the place where the object model of Ruby is explained. Without it, the rest of the book will seem to rely a bit too much on your faith. Unless, of course, you enjoy discovering the truth behind the magic for yourself. I'm sure it is possible and fun, but if you cannot spend the extra time, do take a peek at that chapter.

This enormous book covers most of what you want to know about Ruby, and everything you never wanted to know. Its overview of the language is decent but seems poorly organized. It jumps back-and-forth between basic and advanced. Beginners would feel lost, while more advanced programmers have to skip around carefully. But if you don't skip around too much, you'll find nuggets that explain things much better than any other Ruby book. It also covers tangential subjects that you won't find in most Ru ...more

I was disappointed with the so-called Pickaxe Bible. If you're looking for purely a reference book with some decent explanations, this book is great. It seems pretty exhaustive for beginner-advanced applications of Ruby and takes care to remain somewhat "framework" neutral by always listing both popular frameworks as well as alternatives. However, a few things stopped this from being a great book: lack of applicable examples and inconsistent formatting. The examples were usually very contrived, ...more

Ok, so I have been teaching myself Ruby since last fall and I am in love with it.

Javascript: too wordy, too many f*%king loops and punctuation, mostly front end, can be used for some programming.

PHP: too many functions, hard to find the one you want, less wordy and loopy than javascript. Back end web programming.

Ruby: Beautiful. Elegant. Simple. Bless it. Very little punctuation, loops only where you need them and a not an overload of built in functions/methods. Back end, needs a compiler. Stil ...more

It's the definitive guide to Ruby, affectionately called PickAxe. You basically have to read it.

Now that I have I've realized that it's a great resource for things but the first part of the book where Ruby is described in a tutorial style was totally useless to me. The examples were a bit boring and the stabs at humor should have really been left unstabbed. All in all it was a perfect example of cookie-cutter programming books.

However - I would HIGHLY recommend the pdf version to those learning ...more

Actually I'm reading a downloaded PDF of the third edition that covers Ruby 1.9. This is my first exposure to this language; I like it. I'm happy to say goodbye to PHP (fuck that language, it is made of garbage).

Um...right, about the book: I like it, seems pretty clear and goes through the language using several different strategies. Seems to function well as both a beginner's guide, in depth tutorial, and reference: a rare feat. Even the Perl "camel book" (3rd edition in particular) doesn't rea ...more

This book is huge and exhaustive, but it's very well organized. I went from knowing absolutely nothing about Ruby to writing useful programs for myself by the end of Chapter 4 (about 50 pages).

Ruby is a big language and I think it warrants a big book. Big human languages (like English) allow concise and elegant speech. Big programming languages allow the same. But they do take longer to learn. Fortunately, Ruby has two things going for it in this regard:

1) It borrows a lot from other languages, This book is huge and exhaustive, but it's very well organized. I went from knowing absolutely nothing about Ruby to writing useful programs for myself by the end of Chapter 4 (about 50 pages).

Ruby is a big language and I think it warrants a big book. Big human languages (like English) allow concise and elegant speech. Big programming languages allow the same. But they do take longer to learn. Fortunately, Ruby has two things going for it in this regard:

1) It borrows a lot from other languages, so the more languages you know, the quicker you'll pick up Ruby.

2) It's nicely designed and fairly consistent, so once you learn something, you can often apply it to other parts of the language.

Chapter 9 was my first big "ooooh!" moment with the language: modules and mixins. (By the way, I think "module" is a really poor choice of word for this functionality and "mixin" has always sounded silly to me. That term dates back to the Flavors object system for Lisp and was taken from the ice cream industry.) But who cares what it's called - it's simple and its pragmatic and it works. Import a module's methods into a class and now the class has those methods. I like this kind of system.

My book was the Second Edition, covering Ruby 1.8. (And yes, it's sat on my shelf since it was current, I'm embarrassed to say.) Some things had changed, but the authors did a great job of correctly predicting the changes. If you see an older copy of this for sale cheap and you want to learn Ruby, don't hesitate to buy it. It's still completely relevant in 2018.

I did actually read the entire second half of the book (the built-in class/module and standard library reference). Of course, it was slow and boring and I'm still going to have to look most of this stuff up later when I need it. However, I strongly believe there is a huge advantage to knowing something is *possible* even if you don't remember quite how to do it. In our modern era of instant reference material online, knowing *what* to look up, what it's *called* is more than half the battle.

Ruby has so much stuff built in, it's almost ridiculous (in a good way). A lot of it is very Unix-oriented (no wonder Ruby can be such a pain to install on Windows - it wants to bring an entire POSIX environment with it!). Ruby clobbers Perl in every possible category and looks good doing it. I can't believe it took me this long to join the fun!

I use Ruby almost daily now. It and this book were everything I could have (reasonably) asked for.

Weird trivia: the entire last 40+ pages starting at Appendix D, continuing through the Index and including the page of advertisements for other Pragmatic Bookshelf titles was repeated at the end of my book. The binding is clearly the correct size, so I imagine a lot of copies went out this way. Epic copy/paste mistake? ...more

Ruby is the fastest growing and most exciting dynamic language out there. If you need to get working programs delivered fast, you should add Ruby to your toolbox.

This book is the only complete reference for both Ruby 1.9 and Ruby 2.0, the very latest version of Ruby.

Would you like to go from first idea to working code much, much faster?

Ruby is the fastest growing and most exciting dynamic language out there. If you need to get working programs delivered fast, you should add Ruby to your toolbox.

This book is the only complete reference for both Ruby 1.9 and Ruby 2.0, the very latest version of Ruby.

2013 marks the 20th anniversary of the Ruby language. We're proud that throughout its history, we've continued to cover the latest version of Ruby.

Ruby is a fully object-oriented language, much like the classic object-oriented language, Smalltalk. Like Smalltalk, it is dynamically typed (as opposed to Java or C++), but unlike Smalltalk, Ruby features the same conveniences found in modern scripting languages such as Perl and Python.

The combination of the power of a pure object-oriented language with the convenience of a scripting language makes Ruby a favorite tool of intelligent, forward-thinking programmers.

The Pickaxe contains four major sections:

An acclaimed tutorial on using Ruby. * The definitive reference to the language. * Complete documentation of all built-in classes, modules, and methods. * Complete descriptions of all 97 standard libraries.

This is the reference manual for Ruby, including a description of all the standard library modules, a complete reference to all built-in classes and modules (including all the new and changed methods introduced by Ruby 1.9, 1.9.2, 1.9.3, and 2.0). It also includes all the new and changed syntax and semantics introduced since Ruby 1.8. Learn about the new parameter passing rules, local variable scoping in blocks, fibers, and the new block declaration syntax, among other exciting new features.

About Ruby 2.0

Ruby 2.0 is a minor update to Ruby 1.9, unlike the more major updates from Ruby 1.8 to Ruby 1.9.

The major language changes in Ruby 2.0 are the addition of keyword arguments and the change to use UTF-8 as the default source file encoding.

There are a number of additions to the standard library, including:

@Enumerator::Lazy@, which adds support for lazy access to potentially infinite lists. * Refinements allow you to encapsulate changes to third-party classes, and scope their application to individual source files, preventing your changes from polluting the global application.

You'll also find that Ruby 2 is faster, and has memory management improvements that make it more server-friendly.

All told, there are over 110 sections of the book that have been flagged and cross-linked to indicate 2.0 content.

What You Need

This book assumes you have a basic understanding of object-oriented programming.

In general, Ruby programmers tend to favor the the command line for running their code, and they tend to use text editors rather than IDEs.

Ruby runs on Windows, Linux, and Macs.

It is the "go to" Ruby book for a reason. If you want to learn Ruby (why wouldn't you?) you pretty much HAVE to read it.

Very nice introduction to a very cool programming language. I like the way the author's started out explaining the language from the point-of-view of describing a hypothetical project that they were going to implement in Ruby and stuck with that metaphor throughout the book (even in the more arcane 'Interfacing Ruby with C' sections).

This book lacks structure and organization. It constantly jumps from simple to complex examples and it's hard to get the author's intention. It's just too confusing. In parallel, I'm reading Apple's Swift book. It's impossible not to compare. I'm not talking about the language, but how the books were structured. Apple targets the reader, making the programmer comfortable with the language. This book is the opposite. It made me feel uncomfortable with Ruby. I might use it as a reference book, but ...more
