内容説明
Learn what many Java programmers have recently discovered: the Clojure language offers a practical alternative for solving demanding problems, using existing Java libraries, frameworks, and services. With this book, you get a solid grounding in Clojure fundamentals, based on the environments you already familiar with-whether you're working with data, concurrency, application interfaces, or other challenges. Learn how this JVM language can make your work simpler and help you be more productive. Clojure Programming demonstrates the language's flexibility and wide use by taking a Java project and converting it to Clojure. This in-depth look also shows Ruby and Python developers that Closure is just as expressive and sophisticated with one added advantage: all the resources of the JVM. * Learn how to switch to Clojure without losing your investment in the Java platform * Understand the advantages of Clojure as a dialect of the Lisp language * Discover how this language works in several problem domains * Apply it in different data environments, including big data solutions with Hadoop * Use Clojure as a scripting language, a driver for Swing/SWT interfaces, and other functions * Deploy large web applications across tens or hundreds of nodes with Clojure

Practical and accessible
2012/4/22
形式:ペーパーバック
This is the most practical book on Clojure I've seen yet. At this point I've almost completely made my way through it. I bought it directly from O'Reilly (not Amazon) because I wanted it in PDF format.
I think what I like most about this book is that the authors have most often chosen to explain things in reference to scripting languages like Ruby and Python, and from business and mundane-data examples, rather than using examples from mathematics or computer science. This choice has made Clojure's power very accessible and easy for me, coming from a linux (Bash, Python, C) and web development (PHP, Ruby, Javascript), background and without any math or CS degrees. I am very grateful to the authors for writing it in such a down-to-earth way so that I have been able to absorb it easily.
I also enjoyed the extensive chapters on the practical use of the language, for things like web development, database access, tooling, and packaging. Also, their approach to discussing Java interop was very helpful to me not having dealt with Java much in the past.
Their extensive use of footnotes to comment their code examples is very helpful. When I find myself reading a line of example code and wondering why they did it that way, the footnote answers my question clearly and simply. I might have preferred actual inline comments rather than footnotes-- less jumping around in the PDF-- but the content is great.
In general, while reading it, every question that comes up in my mind seems to be answered within that paragraph or the next one (or in a footnote); the overall flow of the book and the path they've taken for building one concept upon another seemed very natural to me.
Even though it's easy to read linearly, I also found it very easy to skip around as well. I found many of the chapters in the Practicum section to be as good or better than the documentation for the projects they describe. The authors seem to account for the fact that readers might do that, and provide links throughout those chapters to earlier chapters of the book. I tend to reach for the book instead of for the documentation for some projects; it's useful as a HOW-TO.
I don't know if people who have a lot of lisp experience or CS degrees would be as grateful for this book as I am. But it has made learning a very powerful language into a fairly painless and straightforward process for me.
If you're coming to Clojure from languages like Ruby, Python, Javascript, etc., I'd recommend "Clojure Programming" as your first step.

A clear, comprehensive, and effective guide to Clojure
2012/4/23
形式:ペーパーバック
Before reading this book, I was proficient with Java, JavaScript, Python, and a few other languages -- all primarily object-oriented and ALGOL-derived. Lisp and Functional Programming (FP) seemed alien and bizarre. But after hearing that people were getting real work done using FP with Scala and Clojure, and hearing Rich Hickey, the creator of Clojure, speak at Strange Loop, I was inspired to get over my apprehension and learn functional programming and Clojure.
I decided it would be unwise to try to learn FP and Clojure at the same time, so I first wrote a program using FP in languages with which I was already familiar: CoffeeScript and Scala. It didn't take long for me to build an appreciation for the paradigm.
Once I felt that I had a decent understanding of FP, I asked on Twitter whether anyone could recommend a book, and got a very enthusiastic recommendation for this one from Sean Corfield. It was available under O'Reilly's pre-release program, so I was able to buy and read pre-release PDFs of the book.
The bottom line is that this book gave me a solid understanding of Clojure and enabled me to learn the language and gradually start using it. The concepts are presented in a thoughtful sequence wherein each one builds on the next, and it's made clear how each element of the language relates to the others.
The writing, examples, and organization are all excellent. And the book gets extra points for going beyond just explaining the language and how to use it, by being extra-comprehensive and covering how to really use the full Clojure ecosystem to build really useful software.
This is worth highlighting: if the book had been comprised of only chapter 1, "Down the Rabbit Hole", and the first 2 parts, "Functional Programming and Concurrency" and "Building Abstractions", it would have been an excellent book which I'd be recommending wholeheartedly. The inclusion of the subsequent parts, "Tools, Platform, and Projects", "Practicums", and "Miscellanea" make the book an invaluable resource and a fantastic value.
Ultimately, the book succeeds in conveying not only Clojure the language, but also the Clojure way, best practices, and key resources.

Chapter 3 alone is worth the price!

I am loving this book. I've spent the last year as a full-time Clojure dev, and I picked up this book hoping it would serve as a good language reference. I was not expecting to find such lucid and approachable writing on the transition from imperative to functional thinking. If you want to know not just *how* to use Clojure, but *why* you'd use Clojure, you'll find plenty of non-contrived examples in this book. Highly, highly recommended.
