Extend and enhance your Java applications with domain-specific *ing in Groovy About This Book Build domain-specific mini languages in Groovy that integrate seamlessly with your Java apps with this hands-on guide Increase stakeholder participation in the development process with domain-specific *ing in Groovy Get up to speed with the newest features in Groovy using this second edition and integrate Groovy-based DSLs into your existing Java applications. Who This Book Is For This book is for Java software developers who have an interest in building domain *ing into their Java applications. No knowledge of Groovy is required, although it will be helpful. This book does not teach Groovy, but quickly introduces the basic ideas of Groovy. An experienced Java developer should have no problems with these and move quickly on to the more involved aspects of creating DSLs with Groovy. No experience of creating a DSL is required. What You Will Learn Familiarize yourself with Groovy *ing and work with Groovy closures Use the meta-programming features in Groovy to build mini languages Employ Groovy mark-up and builders to simplify application development Familiarize yourself with Groovy mark-up and build your own Groovy builders Build effective DSLs with operator overloading, command chains, builders, and a host of other Groovy language features Integrate Groovy with your Java and JVM based applications In Detail The times when developing on the JVM meant you were a Java programmer have long passed. The JVM is now firmly established as a polyglot development environment with many projects opting for alternative development languages to Java such as Groovy, Scala, Clojure, and JRuby. In this pantheon of development languages, Groovy stands out for its excellent DSL enabling features which allows it to be manipulated to produce mini languages that are tailored to a project’s needs. A comprehensive tutorial on designing and developing mini Groovy based Domain Specific Languages, this book will guide you through the development of several mini DSLs that will help you gain all the skills needed to develop your own Groovy based DSLs with confidence and ease. Starting with the bare basics, this book will focus on how Groovy can be used to construct domain specific mini languages, and will go through the more complex meta-programming features of Groovy, including using the Abstract Syntax Tree (AST). Practical examples are used throughout this book to de-mystify these seemingly complex language features and to show how they can be used to create simple and elegant DSLs. Packed with examples, including several fully worked DSLs, this book will serve as a springboard for developing your own DSLs. Style and approach This book is a hands-on guide that will walk you through examples for building DSLs with Groovy rather than just talking about "metaprogramming with Groovy". The examples in this book have been designed to help you gain a good working knowledge of the techniques involved and apply these to producing your own Groovy based DSLs.

In this inspirational autobiography, Captain "Sully" Sullenberger, the airline pilot whose emergency landing on the Hudson River earned the world's admiration, tells his life story and talks about the essential qualities that he believes have been so vital to his success. In January 2009, the world witnessed one of the most remarkable emergency landings in history when Captain Sullenberger brought a crippled US Airways flight onto the Hudson River, saving the lives of all of the passengers and crew aboard. The successful outcome was the result of effective teamwork, Sully's dedication to airline safety, his belief that a pilot's judgment must go hand-in-hand with and can never be replaced by technology, and forty years of careful practice and training. From his earliest memories of learning to fly as a teenager in a crop duster's single-engine plane in the skies above rural Texas to his years in the United States Air Force at the controls of a powerful F-4 Phantom, Sully describes the experiences that have helped make him a better leader, particularly the importance of taking responsibility for everyone in his care. And he talks about what he believes is at the heart of America's "can do" spirit: the very human drive to prepare for the unexpected and to meet it with optimism and courage. His wife, Lorrie, has been a pillar of support through all the highs and lows that life has offered, from the challenges of commercial flying to the birth of their two daughters, from financial struggles to the event of January 15, 2009. Though the world may remember Sully as the hero of Flight 1549, the legacy he desires even more is that of a loving husband and father. Highest Duty is the intimate story of a man who has grown up to embrace what we think of as quintessential American values leadership, responsibility, commitment to hard work, and service to others. And it is a narrative that reminds us that cultivating seemingly ordinary virtues can prepare us to perform extraordinary acts.
