Clojure Programming Cookbook

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!

Logic programming in Clojure


"Logic will get you from A to B. Imagination will take you everywhere."

 --Albert Einstein

This recipe is going to be a hell of a ride recipe. Strap yourself in. Get a shot of tequila. This is hardcore. So many fun things to learn! But first, what is logic programming? In one sentence, I would say:

Logic programming is a technique that enables you to find goals, given a set of statements or facts.

Again, this is the author's way of presenting logic programming. There is much more academic language being used on the Internet if you are interested. Anyway. What does that mean in easy-to-read terms? Let's see an example.

Say you want to find all the solutions where x is not equal to 2, and x is in the list (1 2 3). Or say, you want to find all the friends of your friends, not your direct friends, that live in Japan, but not in Tokyo.

This is the type of problem logic programming usually helps you solve.

While there is good amount of tutorials available on the subject...
