It’s easy to write correct Ruby code, but to gain the fluency needed to write great Ruby code, you must go beyond syntax and absorb the “Ruby way” of thinking and problem solving. In Eloquent Ruby, Russ Olsen helps you write Ruby like true Rubyists do–so you can leverage its immense, surprising power.

Olsen draws on years of experience internalizing the Ruby culture and teaching Ruby to other programmers. He guides you to the “Ah Ha!” moments when it suddenly becomes clear why Ruby works the way it does, and how you can take advantage of this language’s elegance and expressiveness.

Eloquent Ruby

starts small, answering tactical questions focused on a single statement, method, test, or bug. You’ll learn how to write code that actually looks like Ruby (not Java or C#); why Ruby has so many control structures; how to use strings, expressions, and symbols; and what dynamic typing is really good for.

Next, the book addresses bigger questions related to building methods and classes. You’ll discover why Ruby classes contain so many tiny methods, when to use operator overloading, and when to avoid it. Olsen explains how to write Ruby code that writes its own code–and why you’ll want to. He concludes with powerful project-level features and techniques ranging from gems to Domain Specific Languages.

A part of the renowned Addison-Wesley Professional Ruby Series, Eloquent Ruby will help you “put on your Ruby-colored glasses” and get results that make you a true believer.

Review

R>Eloquent Ruby is like programming in Ruby itself: fun, surprisingly deep, and you'll find yourself wishing it was always done this way. Wherever you are in your Ruby experience from novice to Rails developer, this book is a must read.

About the Author

Russ Olsen’s career spans three decades, during which he has written everything from graphics device drivers to document management applications. These days, he diligently codes GIS, web service security, and process automation solutions. He spends much of his otherwise free time writing and speaking about programming, especially Ruby and Clojure. His first book was the highly regarded Design Patterns In Ruby (Addison-Wesley, 2007). He is also the lurking presence behind the Technology As If People Mattered blog at www.russolsen.com.

Excellent Work

Reviewed in the United States 🇺🇸 on December 29, 2013

Verified Purchase

After programming for years in static typed languages, I needed to learn Ruby for use at my professional work place. I started with "Learning Ruby The Hard Way" per recommendation from a fellow co-worker - it served as decent introduction. Then I switched to Eloquent Ruby even though I was recommended a different book since the reviews for this book were extremely positive. I was not disappointed. In addition to teaching the language, this book covers the ruby way of doing things and the reasoning behind why it's done that way. Such a treatment of the subject is a welcome change for me. Now I can understand the Ruby based conversations among my co-workers much better with this background. This is an extremely well written book with a lot of examples and it has been a pleasure to read. The author's writing style is very engaging - I'm impressed so much that I'll be checking out other books from the same author (notably Ruby Design Patterns). The chapter on regular expressions is excellent and I haven't seen a clearer explanation of it in other books I have referred to in the past. The "Staying Out of Trouble" section at the end of every chapter is helpful even though some of it will be obvious for the reader. "In the Wild" section that illustrates usage in real world code/frameworks of the concepts learned in a chapter is also useful as it helps to reinforce the learning process. This is not a book to read once and then leave on the shelf - I envision myself coming back to this book on an ongoing basis as I continue to develop Ruby applications. Highly recommended.

Teaches idiomatic Ruby; an easy read

Reviewed in the United States 🇺🇸 on March 18, 2014

Verified Purchase

I enjoyed reading this book, and found it to be a useful adjunct to other learning materials. The technical content is very clearly presented, with just the right amount of detail to get the point across, and not much more. The author's tone is somewhat light-hearted, without being cloyingly jocular. Where the book differs from most tutorials is that it focuses on teaching Ruby that is not just "correct", but also idiomatic. I now understand better how, for example, Rails is able to work its various "magic" using various Ruby idioms. That said, I'm not entirely comfortable with the enthusiasm with which the author embraces some of Ruby's "magical" capabilities. I wonder how easy it might be to get carried away with some of these idioms and end up writing a bunch of difficult-to-understand, difficult-to-maintain code. However, insofar as this sort of jazz is part of idiomatic Ruby, I suppose the author is fulfilling his mandate by promoting it; so I hesitate to deduct a star just on account of my own scruples here. On the whole, I recommend this book - especially if you are coming from a more traditional object-oriented language (C++, Java) - and have yet to appreciate just how flexible (sometimes worryingly so) Ruby really is.

Strategist

Reviewed in the United States 🇺🇸 on July 26, 2014

Verified Purchase

It does a decent job. But it's still too long, and the explanations aren't as practical, but tend to go quite into the deep theoretical rabbit hole that veers away from real code usage (ignores how useful and frequent certain concepts are, but goes into them anyway, without regard to how frequent or how useful they may be.) It's not bad, but I wouldn't be trying to learn ruby right off the bat with a book that doesn't do an excellent job with concise explanations, and saves me time. I'd go to the many online resources that covers the main, more used aspects of ruby much more quickly and interactively instead.

Becoming an expert is an iterative process, not reading a book, and then suddenly knowing everything.

Still, is is thorough, and it does provide sufficient examples. I'd leave this book for after you got your hands dirty with ruby via online courses, and maybe then, not even so. You can jump into rails to actually create things with a bit of ruby knowledge to start, and learn ruby better while using it, (like that parentheses are optional for comma-separated arguments, that if a hash is the last argument, then you also don't need to use parentheses, blocks, procs, lambas, etc.

This ruby book is for people who've familiarized with ruby, built apps by following tutorials with rails, gotten hired as a junior developer, and is now needing to know ruby much better to work with production-level apps that seasoned developers utilize.

A good reference for some . . .

Reviewed in the United States 🇺🇸 on January 1, 2016

Verified Purchase

Overall, Russ Olsen's Eloquent Ruby is a good book. I feel that the book would be fantastic for anyone coming to Ruby with an in-depth knowledge of another programming language.

My main reason for giving it four stars instead of five is that this edition is a bit dated (it focuses on Ruby 1.9) and the content while broad in scope is not as in depth as I'd hoped for. Also, it should be noted that Eloquent Ruby is written more like a reference book than a "how-to" or textbook (ie - while Russ Olsen does offer real world examples at the end of chapters, this book is not written with the express purpose of teaching you how to code using the Ruby programming language, or giving you multiple or one large scale "project" to work through with the authors guidance).

I found it very useful

Reviewed in the United States 🇺🇸 on October 12, 2013

Verified Purchase

I am new to Ruby but not to programming and I don't use Ruby with any regular basis. Months before reading this book I had superficially gone over the "The Ruby Programming Language" and maybe one or two tutorials. So, I had only a vague idea.

When I bought the book, I wanted to see (and learn from) idiomatic Ruby code. Particularly, I was interested in getting an overview of the language and, I assumed, a book with this title would not only give me that but would also discuss why and when to best use certain approaches and features in this language.

This book was awesome. It surpassed my expectations, it explained clearly when to use a feature and when to avoid it, it went over how certain features are implemented, and now I have a better understanding of Ruby. It also provided a discussion on tools I didn't previously know which happen to have counterparts in languages I use more regularly (e.g., for work), and, as a consequence, it indirectly helped me outside of its original scope.

an OG for a reason

Reviewed in Canada 🇨🇦 on June 1, 2020

Transitioning from prose to programming = harder than I expected for my brain. This look clarifies what it means to be writing in RUBY specifically: the grammar/syntax that give a sentences its linguistic flair. Just as in translation between human languages, the difference between good writing and great writing is in how well you understand the soul of that language. This book helped me, as a truly mediocre beginner, see how un-Ruby my thinking (and therefore, coding) was.

I think if you're not a complete n00b to programming paradigms, you might not really benefit from reading this because you'll naturally pick up on what Ruby means in comparison to other languages.

Also, the author is funny and sharp. Well-written and a pleasure to read.

Excelent and concise

Reviewed in Brazil 🇧🇷 on June 21, 2016

Goes straight to the matter.

If you already know a bit of Ruby or other programming languages and you want to get a solid grip on how Ruby works (the language and the community), this book is an excelent choice.

It is short and concise but does not fall short in any subject.

I really loved reading it.

I loved this book. Read it twice, and bought a copy for a friend. Russ is an excellent author.

The book dives right into content -- perhaps not the best for people new to Ruby, but I found that if you keep reading he does a good job of introducing all the concepts gently (for the most part). I prefer this over a book that does not discuss the for-loop until Chapter 9.

Close to the end of the book there are a few chapters on metaprogramming.
