Guillaume LaForge
Head of Groovy Development for SpringSource
As Head of Groovy Development for SpringSource, Guillaume Laforge is the official Groovy Project Manager, and the spec lead of JSR-241, the Java Specification Request that standardizes the Groovy dynamic language. He is also a frequent conference speaker presenting Groovy and Grails at JavaOne, SpringOne, QCon, the Sun TechDays, and JavaPolis. Guillaume also co-authored Groovy in Action along with Dierk König. Before founding G2One, which was acquired by SpringSource in late 2008, and taking the role of VP Technology, Guillaume worked for OCTO Technology, a consultancy focusing on architecture and agile methodologies. While at OCTO, Guillaume developed new offerings around Groovy and Grails for its customers.

By Guillaume LaForge
Understanding the domain within which customers evolve is a key factor in the success of a project. From this domain and its wealth of concepts, as software developers and architects, we can derive a design that is aimed at solving problems encountered in the day-to-day business.
So far, we mostly solved these brainteasers with computer science paradigms like Object-Oriented Programming, n-tier architectures, or with tools such as rules engines to stay close to the domain at hand. However, with the advent of dynamic languages, a new era has come to let you create languages taylored to a given domain of knowledge, allowing you to share a common methaphore of understanding between developers and subject matter experts.
Groovy, the popular and successful dynamic language for the JVM, offers a lot of features that allow you to create embedded Domain-Specific Languages. Closures, metaprogramming, operator overloading, named arguments, a more concise and expressive syntax, are elements of Groovy you can take advantage of to create your own mini derived language.
The purpose of this presentation is to show how to write such DSLs in Groovy, discovering in turn those various techniques, with pratical and concrete examples taken from real-life projects leveraging Groovy DSLs.

"... a clear and detailed exposition of what is groovy about Groovy. I'm glad to have it on my bookshelf."
--From the Foreword by James GoslingGroovy, the brand-new language for the Java platform, brings to Java many of the features that have made Ruby popular. Groovy in Action is a comprehensive guide to Groovy programming, introducing Java developers to the new dynamic features that Groovy provides. To bring you Groovy in Action, Manning again went to the source by working with a team of expert authors including both members and the Manager of the Groovy Project team. The result is the true definitive guide to the new Groovy language.
Groovy in Action introduces Groovy by example, presenting lots of reusable code while explaining the underlying concepts. Java developers new to Groovy find a smooth transition into the dynamic programming world. Groovy experts gain a solid reference that challenges them to explore Groovy deeply and creatively.
Because Groovy is so new, most readers will be learning it from scratch. Groovy in Action quickly moves through the Groovy basics, including:
* Simple and collective Groovy data types
* Working with Closures and Groovy Control Structures
* Dynamic Object Orientation, Groovy styleReaders are presented with rich and detailed examples illustrating Groovy's enhancements to Java, including
* How to Work with Builders and the GDK
* Database programming with GroovyGroovy in Action then demonstrates how to Integrate Groovy with XML, and provides,
* Tips and Tricks
* Unit Testing and Build Support
* Groovy on WindowsAn additional bonus is a chapter dedicated to Grails, the Groovy Web Application Framework.
