Programming Clojure


If you’re a Java programmer, if you care about concurrency, or if you enjoy working in low-ceremony language such as Ruby or Python, we’ve got a great new language for you.

In Programming Clojure (Pragmatic Bookshelf, $32.95), author Stuart Halloway shows how to write applications in a modern, concurrency-safe functional style, with the reach of the Java Virtual Machine, the simplicity of a scripting language, and the power and elegance of Lisp.

Clojure is a general-purpose language with direct support for Java, a modern Lisp dialect, and support in both the language and data structures for functional programming. Programmers “in the know” are embracing Clojure to write beautiful code that runs fast and scales well.

Stuart Halloway says, “Clojure feels like a general-purpose language beamed back from the near future. Its support for functional programming and software transactional memory is well beyond current practice and is well suited for multicore hardware. It brings together Lisp and the Java Virtual Machine: Lisp brings wisdom spanning most of the history of programming, and Java brings the robustness, extensive libraries, and tooling of the dominant platform available today.”

Implemented as a dynamic language for the Java Virtual Machine, Clojure comes with a compelling combination of features:

  • Clojure is elegant. Clojure’s clean, careful design lets you write programs that get right to the essence of a problem, without a lot of clutter and ceremony.
  • Clojure is Lisp reloaded. Clojure has the power inherent in Lisp, but is not constrained by the history of Lisp.
  • Clojure is a functional language. Data structures are immutable, and functions tend to be side-effect free. This makes it easier to write correct programs, and to compose large programs from smaller ones.
  • Clojure is concurrent. Rather than error-prone locking, Clojure provides software transactional memory.
  • Clojure embraces Java. Calling from Clojure to Java is direct, and goes through no translation layer.
  • Clojure is fast. Wherever you need it, you can get the exact same performance that you could get from hand-written Java code.

Many other languages offer some of these features, but the combination of them all makes Clojure sparkle. Programming Clojure shows you why these features are so important, and how you can use Clojure to build powerful programs quickly.

There’s a lot of excitement building around Clojure, and Programming Clojure will show you why.
