Sven Efftinge (sven.efftinge@itemis.de)

Release Review : June 11, 2010

Communication Channel : eclipse.modeling.tmf newsgroup

Process Documentation : http://www.eclipse.org/projects/dev_process/development_process.php

Overview

Xtext is a framework for development of programming languages and domain specific languages (DSLs). Just describe your very own DSL using Xtext's simple EBNF grammar language and the generator will create a parser, an AST-meta model (implemented in EMF) as well as a full-featured Eclipse text editor from that.

The Framework integrates with technology from Eclipse Modeling such as EMF, GMF, M2T and parts of EMFT. Development with Xtext is optimized for short turn-arounds, so that adding new features to an existing DSL is a matter of minutes. Still sophisticated programming languages can be implemented.

Features

In this release Xtext has matured to a full-blown language development framework, providing JDT-like IDE support for your languages. Most noteworthy are the

  • builder infrastructure
  • indexing infrastructure
  • dirty state support
  • quick fixes based on model or text
  • etc. (See New & Noteworthy)

Non-Code Aspects

Documentation has been overhauled and extended. The examples are now shipped via EMF's example wizard.

Testing & Packaging

Xtext now makes use of the eclipse.org Hudson new continuous build system.

The continuous build includes running approx. 3500 testcases.

Xtext is integrated into the Helios Release Train since Oktober 2009.
