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.
Chas Emerick is the founder of Snowtide Informatics, a small software company in Western Massachusetts. Since 2008, he has helped to develop the core Clojure language and many Clojure open source projects. Chas writes about Clojure, software development practices, entrepreneurship, and other passions at cemerick.com.
Brian Carper is a professional programmer in the field of psychological research. He uses Clojure for data analysis and web development. He's the author of a Clojure-to-CSS compiler and relational database library, and writes about Clojure and other topics at http://briancarper.net.
Christophe Grand is an independent consultant, based near Lyon, France. He tutors, trains and codes primarily in Clojure. A participant in developing the core Clojure language, he also authored the Enlive and Moustache libaries and is a contributor to Counterclockwise, the Clojure IDE for Eclipse. Christophe writes on Clojure at clj-me.cgrand.net.
Each recipe includes code that you can use right away, along with a discussion on how and why the solution works, so you can adapt these patterns, approaches, and techniques to situations not specifically covered in this cookbook.Master built-in primitive and composite data structuresCreate, develop and publish libraries, using the Leiningen toolInteract with the local computer that’s running your applicationManage network communication protocols and librariesUse techniques for connecting to and using a variety of databasesBuild and maintain dynamic websites, using the Ring HTTP server libraryTackle application tasks such as packaging, distributing, profiling, and loggingTake on cloud computing and heavyweight distributed data crunchingDive into unit, integration, simulation, and property-based testingClojure Cookbook is a collaborative project with contributions from some of the world’s best Clojurians, whose backgrounds range from aerospace to social media, banking to robotics, AI research to e-commerce.
The first half of the book takes you through Clojure’s unique design and lets you try your hand at two Clojure projects, including a web app. The holistic course in second half provides you with critical tools and resources, including ways to plug into the Clojure community.Understand the basic structure of a Clojure expressionLearn how to shape and control code in a functional wayDiscover how Clojure handles real-world state and concurrencyTake advantage of Java classes and learn how Clojure handles polymorphismManage and use libraries in a Clojure projectUse the core.async library for asynchronous and concurrent communicationExplore the power of macros in Clojure programmingLearn how to think in Clojure by following the book’s seven-week training course
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.
