Clojure for Java Developers

Overview of this book

We have reached a point where machines are not getting much faster, software projects need to be delivered quickly, and high quality in software is more demanding as ever. We need to explore new ways of writing software that helps achieve those goals. Clojure offers a new possibility of writing high quality, multi-core software faster than ever, without having to leave your current platform. Clojure for Java developers aims at unleashing the true potential of the Clojure language to use it in your projects. The book begins with the installation and setup of the Clojure environment before moving on to explore the language in-depth. Get acquainted with its various features such as functional programming, concurrency, etc. with the help of example projects. Additionally, you will also, learn how the tooling works, and how it interacts with the Java environment. By the end of this book, you will have a firm grip on Clojure and its features, and use them effectively to write more robust programs.

Using Maven dependencies


Let's say that we want to write an image manipulation program; it is a very simple program that should be able to create thumbnails. Most of our codebase is in Clojure, so we want to write this in Clojure too.

There are a bunch of Java libraries meant to manipulate images, we decide to use imgscalr, which is very simple to use and it looks like it is available in Maven Central (http://search.maven.org/).

Let's create a new Leiningen project, as shown:

lein new thumbnails

Now, we need to edit the project.clj file in the thumbnails project:

(defproject thumbnails "0.1.0-SNAPSHOT"
  :description "FIXME: write description"
  :url "http://example.com/FIXME"
  :license {:name "Eclipse Public License"
            :url "http://www.eclipse.org/legal/epl-v10.html"}
  :dependencies [[org.clojure/clojure "1.6.0"]])

You can add the imgscalr dependency similar to the following code:

(defproject thumbnails "0.1.0-SNAPSHOT"
  :description "FIXME: write description"
  :url "http://example...
