C++ is usually synonymous with object-oriented programming (OOP), and further replenished in no small measure by popular technical literature. This article tries something different—functional programming with C++ using the open source FC++ library from Yannis Smaragdakis and Brian McNamara. Learn how you can use FC++ to implement basic functional programming.

Internal DSLs are possible but cumbersome in the Java language because of its restrictive syntax. This article covers some of the capabilities you can exploit and issues you'll encounter when using Groovy to build internal DSLs.

A burst of innovation in the open source world over the last few years has led to an increase in Java developer productivity. A promising new entry on the scene is Apache CouchDB, hailed by some as the database for Web 2.0. This Java development 2.0 column introduces CouchDB and shows you how Groovy's RESTClient can help you tap into its strengths.

Provisioning an EC2 instance for hosting a Java Web application is a snap. In this Java development 2.0 column, you'll quickly build a Web application that leverages Groovy, Spring, and Hibernate (via the Grails framework) and deploy it on an EC2 instance.

This article tackles a topic that strikes fear into most server-side Java developers: Swing. As you'll learn, Groovy's SwingBuilder takes some of the sting out of this powerful yet complex GUI framework. Also see how a Twitter GUI written in Groovy might look like.

In this Mastering Grails installment, Scott Davis shows you how to create your own Grails plug-in. Once you see how effortless it is to create a plug-in, you'll understand why more than 250 Grails plug-ins are available now, with new ones being added all the time.

The ability to add new methods to classes dynamically at run time — even Java classes, and even final Java classes — is incredibly powerful. Whether used for production code, unit tests, or anything in between, Groovy's metaprogramming capabilities should pique the curiosity of even the most jaded Java developer.

To be a successful software developer in this day and age, you need a set of tools that makes dealing with XML effortless. Groovy introduces new and better ways to create and process XML. With the help of some examples, this article shows you how Groovy makes building and parsing XML refreshingly simple.
