Xtext/Galileo

TMF Xtext 0.7.0

Xtext is a framework used to develop textual, EMF-based domain-specific languages (DSL). TMF Xtext is a complete rewrite of the currently released version known from openArchitectureWare (oAW Xtext). Itʼs not compatible with oAW Xtext. However, many concepts are obviously very similar. At itʼs heart Xtext itself provides a DSL (the grammar language) used to describe the concrete and abstract syntax of a DSL.

The main focus of the rewrite is to improve overall performance and scalability. It is also a major goal to have stable and simple Java API, and provide different convenient APIs and DSLs on top.

Based on a grammar Xtext offers language-specific functionality such a parsers, printers, editors and other tooling stuff. Xtext comes with simple but reasonable default implementations of common language aspects (such as scoping and linking), but also provides the necessary hooks to change the behavior of all kinds of things if needed.
