Chapter 2. Creating Your First Xtext Language
In this chapter we will develop a DSL with Xtext and learn how the Xtext grammar language works. We will see the typical development workflow of programming with Xtext when we modify the grammar of the DSL. The chapter will also provide a small introduction to EMF (Eclipse Modeling Framework), a framework that Xtext relies upon to build the AST (Abstract Syntax Tree) of a program.
A DSL for entities
We will now implement a simple DSL to model entities, which can be seen as simple Java classes; each entity can have a super type entity (you can think of it as a Java superclass) and some attributes (similar to Java fields). This example is a variant of the domain model example that can be found in the Xtext ...
