Drowning in unnecessary complexity, unmanaged state, and tangles of spaghetti code? In the best tradition of Lisp, Clojure gets out of your way so you can focus on expressing simple solutions to hard problems. Clojure cuts through complexity by providing a set of composable tools--immutable data, functions, macros, and the interactive REPL. Written by members of the Clojure core team, this book is the essential, definitive guide to Clojure. This new edition includes information on all the newest features of Clojure, such as transducers and specs.
Clojure joins the flexibility and agility of Lisp with the reach, stability, and performance of Java. Combine Clojure's tools for maximum effectiveness as you work with immutable data, functional programming, and safe concurrency to write programs that solve real-world problems.
Start by reading and understanding Clojure syntax and see how Clojure is evaluated. From there, find out about the sequence abstraction, which combines immutable collections with functional programming to create truly reusable data transformation code. Clojure is a functional language; learn how to write programs in a functional style, and when and how to use recursion to your advantage. Discover Clojure's unique approach to state and identity, techniques for polymorphism and open systems using multimethods and protocols, and how to leverage Clojure's metaprogramming capabilities via macros. Finally, put all the pieces together in a real program.
New to this edition is coverage of Clojure's spec library, one of the most interesting new features of Clojure for describing both data and functions. You can use Clojure spec to validate data, destructure data, explain invalid data, and generate large numbers of tests to verify the correctness of your code.
With this book, you'll learn how to think in Clojure, and how to take advantage of its combined strengths to build powerful programs quickly.

If you want to keep up with the significant changes in this important language, you need the second edition of Programming Clojure. Stu and Aaron describe the modifications to the numerics system in Clojure 1.3, explain new Clojure concepts such as Protocols and Datatypes, and teach you how to think in Clojure. Programming Clojure, 2nd Edition is a significant update to the classic book on the Clojure language. You'll get thorough coverage of all the new features of Clojure 1.3, and enjoy reorganized and rewritten chapters that reflect the significance of new Clojure concepts. Many code examples have been rewritten or replaced, and every page has been reevaluated in the light of Clojure 1.3. As Aaron and Stu show you how to build an application from scratch, you'll get a rich view into a complete Clojure workflow. And you'll get an invaluable education in thinking in Clojure as you work out solutions to the various parts of a problem. Clojure is becoming the language of choice for many who are moving to functional programming or dealing with the challenges of concurrency. Clojure offers: The simplicity of an elegantly designed language The power of Lisp The virtues of concurrency and functional style The reach of the JVM The speed of hand-written Java code It's the combination of these features that makes Clojure sparkle. Programming Clojure, 2nd Edition shows you how to think in Clojure, and to take advantage of these combined strengths to build powerful programs quickly. What You Need: Oracle JDK 6 A text editor
