Clojure in Action, Second Edition

Clojure is a relatively new version of Lisp that runs on the Java Virtual Machine. It's a functional language, which means that it's ideal for the growing need for concurrent programming and for specialized tasks like creating domain specific languages. __Clojure in Action, Second Edition__ is a fully-revised edition that covers the new features available in Clojure 1.5. This easy-to-follow tutorial provides a rapid introduction to the Clojure language and starts by showing how to use Clojure as a general purpose language. It looks at Clojure's efficient concurrency model, which is based on the familiar database concept of Software Transactional Memory (STM) and helps readers find a new level of productivity through Clojure DSLs that run on the JVM. Using this book, readers will discover countless tips, tricks, and techniques for writing smaller, faster, and safer code. Purchase of the print book comes with an offer of a free PDF, ePub, and Kindle eBook from Manning. Also available is all code from the book. Annotation SummaryA fully revised edition that covers the new features available in Clojure 1.6. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. About the TechnologyClojure is a modern Lisp for the JVM. It has the strengths you expect: first-class functions, macros, and Lisp's clean programming style. It supports functional programming, making it ideal for concurrent programming and for creating domain-specific languages. Clojure lets you solve harder problems, make faster changes, and end up with a smaller code base. It's no wonder that there are so many Clojure success stories. About the BookClojure in Action, Second Edition is an expanded and improved version that's been updated to cover the new features of Clojure 1.6. The book gives you a rapid introduction to the Clojure language, moving from abstract theory to practical examples. You'll start by learning how to use Clojure as a general-purpose language. Next, you'll explore Clojure's efficient concurrency model, based on the database concept of Software Transactional Memory (STM). You'll gain a new level of productivity through Clojure DSLs that can run on the JVM. Along the way, you'll learn countless tips, tricks, and techniques for writing smaller, safer, and faster code.
