Je suis encore en pleine lecture de ce livre mais j'avoue que l'approche et la pédagogie employée par l'auteur est vraiment géniale. Tout est basé sur l'approche objet et cela permet de se poser des questions sur la manière dont sont gérés les objets dans les autres langages tels que Java...
Je suis aussi vraiment agréablement surpris par la syntaxe de Ruby même si c'est un peu difficile à appréhender au début

En tout cas je le recommande pour tous les niveaux

Le livre convient parfaitement aux développeurs ayant une expérience dans des langages type C++, Java, C# et qui souhaitent apprendre Ruby. J'en suis au chapitre 9 (sur 15) et je peux enfin lire et comprendre un programme écrit en Ruby ! (et bien évidemment en écrire !).

the best, first book to discover ruby ... 6 juin 2009
Par grantmichaels - Publié sur Amazon.com
Format: Broché
i've had a tenuous relationship w/ ruby for the past 18 months, which began when a friend sent me the 'pickaxe' and agile rails books over the 2007 holidays. that duo is widely regarded as the de facto introduction to programming with ruby on rails, however, i'd qualify that statement to perhaps only apply to working professionals coming over from another language/framework. i both 1) don't think rails is the best framework for a new ruby coder (sinatra is), and 2) don't think the Pragmatic book is the best introduction to ruby. the well-grounded rubyist didn't exist when i got started, so the first book to pique my interest was the 'beginning ruby' book by peter cooper (apress), and while i was very happy to have found that title over a year ago and having purchased several books and screencasts related to ruby since, the well-grounded rubyist is absolutely the best book to become familiar with ruby at present. the reasoning is consistent w/ my reviews of other books for other programming languages, and is such that there is /NO REPLACEMENT/ for the author being a first-rate educator. a quality instructor is somewhat selfless, always focused on presenting the subject as a first priority, and particularly not how the subject relates to themselves. most programming books are written by practitioners, and since ruby hasn't become particularly available as an option for computer-science students in most programs, there is a very definite void in regard to the number of real teachers writing texts on ruby. i had struggled against my previous experiences coding (asm) and while i learned a lot of the tactics to code in ruby over the past year and half, i never really understood 'why' things worked the way they did. whereas before reading this book i was primarily remixing other people's code, now i'm writing my own code and it feels much more natural. just as "jQuery in action" seemed to open my eyes to the world of javascript, this Manning title has finally opened up the rubiverse and to say that i'm ecstatic really just begins to do this book justice. i can't imagine that you wouldn't find this book the best place to start w/ ruby at this time ...

important read 25 juin 2009
Par J. Mucsi - Publié sur Amazon.com
Format: Broché Achat vérifié
If you have any doubts about your Ruby knowledge, then you should read this book. After months of frustration while looking at source code and wasting time with Why's Poignant Guide, I made it a point to read through all pages of the Well-Grounded Rubyist. Once I was done, the difficulty was gone. Now I can read Rails code with ease, all the code makes sense and I feel like I entered a whole new world. David Black guides the reader through the topics he feels are most important. I resisted the temptation to put down the book and start programming, but I am glad I waited. The book is so useful that having finished it, you will be on a new level and your next task will be to learn how Ruby's powerful features can be combined into non-trivial frameworks. If you skip this book, you risk writing mediocre code, at least until you are forced to learn the features and techniques of the language...the hard way.

Very disciplined, accurate, language tutor 16 août 2009
Par New England Yankee - Publié sur Amazon.com
Format: Broché
David Black has written a thoughtfully balanced book on Ruby basics and best practices. Thankfully, it doesn't waste a single page on things better off on a website somewhere. For example, no elaboration of differences between Ruby 1.9.1 and earlier versions. (Which are, in fact, found on the book's website!)

The book is written referencing Ruby 1.9.1. Be aware that as of this writing, there isn't a 1-click installer on the Ruby language site for 1.9.1 for Windows, and the binaries-only download doesn't include a few key DLLs. If you want to continue using 1.8.6 until an up-to-date installer comes along, the bulk of the book will still be perfectly usable, however. The last note on Windows is that there is text sprinkled throughout the book on such things as paths and other configuration minutia which is specific to Mac and Unix installs. This should not trouble the readers intended for this book in the least.

As a practical matter, since the author spends no time on basic programming concepts, you'll have to have some programming experience to take best advantage of this book. Expressed differently, there is no wasted text for its audience. As one with such experience, I found this to be a perfectly-conceived bootstrap approach to the language. Anyone already having basic OO concepts already should have no difficulty following this book (mine being Smalltalk).

The author and publisher appear to have taken great pains in the flow, layout, and editing to produce a virtually error-free work. I'm enormously appreciative of that; for its own sake, of course, but also because error-riddled computer book are all too common. There are some very minor errors posted on the book's blog on the publisher's website, but they are trivial, in my opinion (programmers are persnickety, particularly about semantics, and rightfully so).

Black's intent is to walk the reader through key aspects of the language, OO as it directly relates to Ruby, and a slice of the core library. Take note of the last comment - this is NOT a comprehensive language reference covering the entire core library. Instead, the author is trying to cover those portions of the library he deems most important to understand when learning Ruby. He succeeds. While the book starts out with the simplest of Ruby's elements, such as syntax, by the end of the volume, you're well into more advanced usages, including reflection, overriding core behavior, and more.

One of the best programming books I've bought in terms of clarity, presentation, and flow. And over 25 years, there have been a lot of them.

review by Eric Grimois 29 juin 2009
Par Developpez.com writers - Publié sur Amazon.com
Format: Broché
"The Well-grounded Rubyist" belongs to these still too rare books which deal exclusively and in-depth with Ruby, by leaving Rails, its killer app, on side. David A. Black proposes to give us a strong foundation for the comprehension of the Ruby's mechanisms. On this purpose, he adopts a didactic and original step, by presenting the concepts according to a progressive and well balanced difficulty, not following the "traditional" progression found in other books treating of computer programming languages. Thus, for example, the method lookup strategy is described in chapter 4, even before looking in detail at the test and loop instructions in chapter 6. This order, which can seem curious at first sight, appears finally perfectly logical and natural. This progressive and cumulative approach will however impose to the reader a linear reading of the book to withdraw all the benefit from it.

Focusing himself on the fundamental mechanisms of Ruby, the author only partially cover its built-in classes and modules library, in the second part of the book. After a long description of essential (predefined classes, conversion methods, enumerators etc) he devotes two whole chapters to the extensive Ruby's possibilities about I/O operations and regular expressions.

The three final chapters, which compose the third and last part of the book, treat dynamic aspects of Ruby. What would appear to be the most complex topic of the book is in fact surprisingly easy to assimilate, and one realizes that the efforts of the author to gradually lead us to a sufficient knowledge of Ruby in order to tackle without pain the most difficult subjects, bore its fruits.

This book is intended more particularly for those who discover Ruby, but will be also advantageous to more advanced Ruby developers. Thus, the talent of the author enabled me to completely understand certain of mechanisms I used without mastering them, and which I never had seen exposed anywhere so clearly. The wise advice of the author, lavished throughout the book, to make good use of the exceptional richness of Ruby will also benefit to all readers.

As good as it is, this book presents however some small defects: the author always wanting to make sure you hit the point, some explanations are slightly verbose, and its deliberate choice to not speak about the important differences occurred between Ruby 1.8 and 1.9 may annoy some readers. But these few defects are really minors in regard of the great qualities of this book, and I completely recommend it.

the best ruby expository 17 décembre 2012
Par tcw - Publié sur Amazon.com

Background: I owned and digested The Ruby Programming Language (TRPL) book by David Flanagan and Yukihiro Matsumoto - which I still value highly and reference regularly. I also own Programming Ruby (2nd and 3rd edition). This is my 1st review on Amazon. After received much benefits from reading others reviews, I figured it was about time I give back.

Ruby is a beautiful and very very powerful language - a language that allows you to write domain specific languages (e.g. RAILs is one of them). To really harvest the power that object oriented paradigm brings to the table, one must master the language.

There are many experts in ruby programming, but only a few that can teach you how to master ruby like Dr. Black can. I've been literally digesting this book for the past several months. Spending hours each week referencing the material discussed in this book, experimenting with the language on my new automation project.

For me this book is worth several thousand $ in value. How did I arrive at the value? I spent a week at my company's ruby class which was taught by some ruby expert costing 2k per person. And I didn't get more than 20% covered in the book. Besides, some of the complex concepts just require time and experiment to sink in. Only a book like this can fulfill such a requirement.

It all depends on what you want to get out of the book. The more time you interact with it, the more value you will get out of it. I definitely recommend entering the example code in irb as you go through the book. It can take you from beginning level all the way to the advance level to go and comfortably read ruby library source codes like the minitest gem source code. I highly recommend reading this source code to test your ability to understand how ruby work.

I see comments about verboseness and repetitiveness. My only response to this is that I wish it was even more verbose. Maybe I'm a slow learner, but I find myself having to re-read each page several times. And even then, I still need to google for additional details. But what Dr. Black covered was adequate for me to investigate further.

There is great cost to the teacher and the student to master something like ruby. For me it was plain sweat and grinding until it sinks in. I'm glad there is someone like Dr. Black who is the master himself, and who is willing to help others getting to the same level.
