Key benefits

Learn to quickly develop a domain-specific language with Xtext Implement any aspect of a DSL using Xtend, a fully featured Java-like programming language Discover how to test a DSL implementation and how to customize runtime and IDE aspects of the DSL

Description

Xtext is an open source Eclipse framework for implementing domain-specific languages together with its IDE functionalities. It lets you implement languages really quickly, and, most of all, it covers all aspects of a complete language infrastructure, starting from the parser, code generator, interpreter, and more. "Implementing Domain-Specific Languages with Xtext and Xtend" will teach you how to develop a DSL with Xtext, an Eclipse framework for implementing domain-specific languages. The chapters are like tutorials that describe the main concepts of Xtext such as grammar definition, validation, code generation, customizations, and many more, through uncomplicated and easy-to-understand examples. Starting with briefly covering the features of Xtext that are involved in a DSL implementation, including integration in an IDE, the book will then introduce you to Xtend as this language will be used in all the examples throughout the book. We then proceed by explaining the main concepts of Xtext, such as validation, code generation, and customizations of runtime and UI aspects. By the end of the book, you will have learned how to test a DSL implemented in Xtext with Junit, in order to follow a test-driven development strategy that will help the developer implement maintainable code that is much faster and cleaner. A test-driven approach is used throughout the book when presenting advanced concepts such as type checking and scoping. The book also shows you how to build and release a DSL so that it can be installed in Eclipse, and gives you hints on how to build the DSL headlessly in a continuous integration server. "Implementing Domain-Specific Languages with Xtext and Xtend" aims to complement the official Xtext documentation to explain the main concepts through simplified examples and to teach the best practices for a DSL implementation in Xtext. It is a Beginner's Guide which should set you up for professional development DSL and its Eclipse IDE tooling.

Who is this book for?

This book is for programmers who want to learn about Xtext and how to use it to implement a DSL (or a programming language) together with Eclipse IDE tooling. It assumes that the user is familiar with Eclipse and its functionality. Existing basic knowledge of a compiler implementation would be useful, though not strictly required, since the book will explain all the stages of the development of a DSL.

What you will learn

Learn to write an Xtext grammar for a DSL Use Xtend as an alternative to Java to write cleaner, easier-to-read, and more maintainable code Write constraint checks for a DSL using the validator mechanism Learn how to write a code generator and an interpreter for a DSL Discover how automatic symbol resolution works in Xtext and how to customize it Build and deploy a DSL implementation so that others can install it Get well versed with the typical Xtext development workflow

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

Excellent! It's an excellent book, with great examples and very didactic text. I recommend it. The introduction to Xtend is very good.

OPCoach Oct 30, 2013

This book gives a full overview of all the powerful features of XText and Xtend, explaining how to manage the auto completion or quick fixes (for instance), and how to test it using JUnit !If you plan to develop a text editor, don't miss this book. It is easy to read, clearly explained and all the examples can be reused for any project.

Alexander Marek Feb 24, 2014

I have been struggeling quite a lot with Xtext as it is a huge framework and I was neither familiar with Xtext, the Eclipse plugin framework and all their naming conventions.Additionally I am currently developing my first textual DSL.This book has helped me a lot!Not only did it give a good introduction into the field of textual DSLs with all the things that belong there, they also do it with simple and well explained examples. I learned how to introduce type systems, do code generation and even write an interpreter.Additionally it gives a lot of insights into the internals of Xtext like how linking works, etc. which also saved me tons of hours as I finally understood the errors and warnings in the Eclipse console that came from Xtext.I can only recommend this book to every interested reader.

Axl Mattheus Nov 06, 2013

This book is extensive without being long winded. It covers most, if not all of the functionality locked away in Xtext. It does a respectable job of introducing Xtend. It is well organized, which makes it easy to skip chapters not of interest to the reader without losing context in later chapters. Examples are concise, focussed, practical and accurate - and the examples work too!Compared to some of the works on other language construction tools, this book is a shining example of what a book on language construction should look like.Caveat: don't take on this book if you do not have some knowledge of language construction. A little knowledge of ANTLR will go a long way as it will make a big difference in dealing with the ANTLR errors/warnings when constructing a new language.Well done Lorenzo and the editors of this book!

Axel Sep 25, 2013

Although I have been working with both Xtext and Xtend for several months already I bought the new book from Lorenzo Bettini as it promised to give a far better total overview regarding advanced use cases and best practices than the official documentation. After having read the whole book I can recommend it to new users interested in model-driven development and also to advanced DSL engineers.The book copes with teaching things in building steps whereby a number of examples is implemented and extended. Even quite complex topics like type systems and scoping are very-well described so readers are not lost in the nowhere.If you think you know already all important aspects of Xtext and Xtend note the book is updated for the 2.4.x series already. Be sure that you will discover some details you missed before, but serve for further improvement of your productivity.
