DESCRIPTION

Every domain of the business world, from sales to warehousing to

shipping, has a language all its own. A DSL, or domain specific

language, is a computer programming language that is created with a

particular domain in mind. Because it uses familiar terminology, and

because it is designed to be simple, a DSL can be used by nontechnical

business people to write or at least change existing programs.

DSLs are developed from normal programming languages, and the

examples in this book are about a subset of those that run on the Java

Virtual Machine, such as Java itself, Ruby, or Scala. DSLs in Action

uses real-world examples to thoroughly guide the reader through the

process of building a DSL.

KEY POINTS

F • In-depth techniques of DSL implementation.

F • Highly practical.

F • Uses real-life applications for illustration.

F • Author is a well-known DSL blogger and expert.

This book is written especially for developers familiar with JVM-based

languages, but many of the techniques presented will work in other

programming environments as well.
Your success-and sanity-are closer at hand when you work at a higher level of abstraction, allowing your attention to be on the business problem rather than the details of the programming platform. Domain Specific Languages-"little languages" implemented on top of conventional programming languages-give you a way to do this because they model the domain of your business problem.

DSLs in Action introduces the concepts and definitions a developer needs to build high-quality domain specific languages. It provides a solid foundation to the usage as well as implementation aspects of a DSL, focusing on the necessity of applications speaking the language of the domain. After reading this book, a programmer will be able to design APIs that make better domain models. For experienced developers, the book addresses the intricacies of domain language design without the pain of writing parsers by hand.

The book discusses DSL usage and implementations in the real world based on asuite of JVM languages like Java, Ruby, Scala, and Groovy. It contains code snippets that implement real world DSL designs and discusses the pros and cons of each implementation.

Purchase of the print book comes with an offer of a free PDF, ePub, and Kindle eBook from Manning. Also available is all code from the book.
