Overview of this book

When it comes to learning and using a new language you need an effective guide to be by your side when things get rough. For Clojure developers, these recipes have everything you need to take on everything this language offers. This book is divided into three high impact sections. The first section gives you an introduction to live programming and best practices. We show you how to interact with your connections by manipulating, transforming, and merging collections. You’ll learn how to work with macros, protocols, multi-methods, and transducers. We’ll also teach you how to work with languages such as Java, and Scala. The next section deals with intermediate-level content and enhances your Clojure skills, here we’ll teach you concurrency programming with Clojure for high performance. We will provide you with advanced best practices, tips on Clojure programming, and show you how to work with Clojure while developing applications. In the final section you will learn how to test, deploy and analyze websocket behavior when your app is deployed in the cloud. Finally, we will take you through DevOps. Developing with Clojure has never been easier with these recipes by your side!

Defining simple macros

Macros in Clojure allow you to redefine the processing flow and generate code through a simple but very Clojure-esque defmacro construct.

This section will guide us through writing some of those building blocks and reading some macro code from the original from Clojure.

Getting ready

Macro-biotics and a spoon are all you need for this recipe. No other agricultural produce required.

How to do it...

All you ever wanted to know about writing simple Clojure macros is in this section. Keep on writing those simple macros until it finally makes sense.

Your first macro

Well, here you go. Your first macro is here:

(defmacro my-very-first-macro []  
  (list println "FIRST")) 

Okay, that was kind of a fast introduction to something that deserves description; it's time to bring you upto speed.

First, the defmacro routine requires a name and some parameters. There you go, we give it the name my-very-first-macro and, being a bit on the greedy side, no parameter...
