Clojure is a practical, general-purpose language that offers expressivity rivaling other dynamic languages like Ruby and Python, while seamlessly taking advantage of Java libraries, services, and all of the resources of the JVM ecosystem. This book helps you learn the fundamentals of Clojure with examples relating it to the languages you know already, in the domains and topics you work with every day. See how this JVM language can help eliminate unnecessary complexity from your programming practice and open up new options for solving the most challenging problems. Clojure Programming demonstrates the language’s flexibility by showing how it can be used for common tasks like web programming and working with databases, up through more demanding applications that require safe, effective concurrency and parallelism, data analysis, and more. This in-depth look helps tie together the full Clojure development experience, from how to organize your project and an introduction to Clojure build tooling, to a tutorial on how to make the most of Clojure’s REPL during development, and how to deploy your finished application in a cloud environment. Learn how to use Clojure while leveraging your investment in the Java platform Understand the advantages of Clojure as an efficient Lisp for the JVM See how Clojure is used today in several practical domains Discover how Clojure eliminates the need for many verbose and complicated design patterns Deploy large or small web applications to the cloud with Clojure

For weeks, months —nay!—from the very moment you were born, you’ve felt it calling to you. At long last you’ll be united with the programming language you’ve been longing for: Clojure! As a Lisp-style functional programming language, Clojure lets you write robust and elegant code, and because it runs on the Java Virtual Machine, you can take advantage of the vast Java ecosystem. Clojure for the Brave and True offers a “dessert-first” approach: you’ll start play­ing with real programs immediately, as you steadily acclimate to the abstract but powerful features of Lisp and functional programming. Inside you’ll find an offbeat, practical guide to Clojure, filled with quirky sample programs that catch cheese thieves and track glittery vampires. Learn how to: *Wield Clojure’s core functions *Use Emacs for Clojure development *Write macros to modify Clojure itself *Use Clojure’s tools to simplify concurrency and parallel programming Clojure for the Brave and True assumes no prior experience with Clojure, the Java Virtual Machine, or functional programming. Are you ready, brave reader, to meet your true destiny? Grab your best pair of parentheses—you’re about to embark on an epic journey into the world of Clojure!

Clojure is the best all-purpose programming language that I have yet to encounter in my software development career. When I first began learning it, I found myself thrilled and satisfied in ways that I can only recall experiencing once beforeùwhen I received my first computer, and entered those first few commands and watched in delight as it responded with precision to my instructions. Over the years, of course, much of the charm of programming wore off. The excitement of imposing my will on a complex machine gradually became lost as I repeatedly slogged through the same exercises and patterns, overcoming with difficulty the inherent complexities of ever-larger systems. But with Clojure, I noticed a curious shift. I began, once more, to enjoy the act of programming. Not just the act of creation and planning, which I've always liked, but even implementing low-level, "everyday" routines. Programming in Clojure is like removing a restrictive suitùonce more, you'll feel like you are actually in control, expressing yourself to the program directly rather than through layers of vaguely necessary indirection. You will be impressed and pleased with Clojure's expressiveness, allowing scope for creativity and original abstractions. Instead of programs becoming more complex and difficult to understand as they grow, Clojure programs become simpler and more expressive. More than that, Clojure will encourage you to try things that are simply too complicated to do regularly in other languages: concurrency, immutability, and lazy data structures. Plus since it runs on the JVM, you can use the same platform, libraries, and tools that you are comfortable with. I hope that this book opens the same doors for you as it did for me, and shows Clojure to be the fun, expressive, and mature language that I have found it to be. Sincerely, Luke VanderHart

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.

Programmieren mit Scala

View: 7328

Sie ist elegant, schlank, modern und flexibel: Die Rede ist von Scala, der neuen Programmiersprache für die Java Virtual Machine (JVM). Sie vereint die Vorzüge funktionaler und objektorientierter Programmierung, ist typsicherer als Java, lässt sich nahtlos in die Java-Welt integrieren – und eine in Scala entwickelte Anwendung benötigt oft nur einen Bruchteil der Codezeilen ihres Java-Pendants. Kein Wunder, dass immer mehr Firmen, deren große, geschäftskritische Anwendungen auf Java basieren, auf Scala umsteigen, um ihre Produktivität und die Skalierbarkeit ihrer Software zu erhöhen. Das wollen Sie auch? Dann lassen Sie sich von den Scala-Profis Dean Wampler und Alex Payne zeigen, wie es geht. Ihre Werkzeugkiste: Schon bevor Sie loslegen, sind Sie weiter, als Sie denken: Sie können Ihre Java-Programme weiter verwenden, Java-Bibliotheken nutzen, Java von Scala aus aufrufen und Scala von Java aus. Auch Ihre bevorzugten Entwicklungswerkzeuge wie NetBeans, IntelliJ IDEA oder Eclipse stehen Ihnen weiter zur Verfügung, dazu Kommandozeilen-Tools, Plugins für Editoren, Werkzeuge von Drittanbietern – und natürlich Ihre Programmiererfahrung. In Programmieren mit Scala erfahren Sie, wie Sie sich all das zunutze machen. Das Hybridmodell: Die Paradigmen "funktional" und "objektorientiert" sind keine Gegensätze, sondern ergänzen sich unter dem Scala-Dach zu einem sehr produktiven Ganzen. Nutzen Sie die Vorteile funktionaler Programmierung, wann immer sich das anbietet – und seien Sie so frei, auf die guten alten Seiteneffekte zu bauen, wenn Sie das für nötig halten. Futter für die Profis: Skalierbare Nebenläufigkeit mit Aktoren, Aufzucht und Pflege von XML mit Scala, Domainspezifische Sprachen, Tipps zum richtigen Anwendungsdesign – das sind nur ein paar der fortgeschrittenen Themen, in die Sie mit den beiden Autoren eintauchen. Danach sind Sie auch Profi im Programmieren mit Scala.
