Model-driven development requires describing models at various levels of abstraction. To describe these models, domain-specific languages & tooling need to be developed. To make this work in practice, efforts for a customized language and IDE must be low.

In order to simplify the development of domain-specific languages (DSLs), we have built the Eclipse Xtext framework which brings advanced IDE features at low implementation effort. We enjoy supporting the Eclipse and Xtext community with our ongoing effort to improve the framework.

What is Xtext?

Xtext is a framework for the development of textual domain-specific languages. Given an EBNF-like grammar, Xtext generates a parser and abstract syntax data structures, and provides the complete infrastructure you expect for a modern language: linking, (semantic) validation, content assist, syntax coloring, goto declaration, find references, rename refactoring and many more features you know from your favourite integrated development environment.

Xtext is designed to get you going quickly. Simple languages can be built within hours, but it is also possible to build fully-featured, statically-typed programming languages like Eclipse Xtend. Xtext comes with good defaults and all aspects can easily be customized to your needs using well-defined configuration hooks.

Xtext DSLs are not restricted to the Eclipse IDE or Eclipse Rich Clients (RCP). Thanks to the Language Server Protocol, you can run them in any editor that supports language servers such as Visual Studio Code or cloud based IDEs such as Eclipse Theia. There is also xtext-web, which allows you to run your DSL in a lightweight browser widget.

Xtext is free

As an Eclipse project, Xtext is published under the Eclipse Public License, one of the most liberal/permissive open source licenses. It can be used free of charge and also be used in commercial projects with no strings attached. Its source code is available on github.

Xtext Success Stories at itemis

Xtext has proven itself in countless industrial projects. It is heavily compatible to previous versions and we’re continuing in putting a lot of efforts into that.

At itemis, we not only create and maintain Xtext, but we also provide services and training to get your company up to speed with your project. However you like it: either we build the DSL for you, or we’ll train you in how to do that yourself.

And since we like to drink our own Whisky, YAKINDU Statechart Tools runs with it.
