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!

Manipulating various formats of files - XML, JSON, YAML, and EDN

There are many formats available to exchange data between different systems these days, but the most important ones seems to be quite stable for some time with a list of XML, JSON, YAML, and, more recently, MessagePack and EDN, a subset of the Clojure notation.

Each of these formats has some strong points, so this recipe will show us how to read and parse data through those different formats, and also when you might want to use each of them.

Getting ready

This recipe will make use of the standard libraries in the Clojure world to parse the different data formats. These are the full set of dependencies that we will need in our projects.clj file:

[clj-yaml "0.4.0"] ; parse yaml 
[cheshire "5.5.0"] ; parse json 
[org.clojure/data.xml "0.1.0-beta1"] ; parse xml 
[com.cognitect/transit-clj "0.8.285"] ; library for both json and msgpack 
[org.clojure/tools.reader "1.0.0-alpha2"] ; EDN...
