4 Steps to get your DSL online!

Get the web plugin to package with RAP, a Maven/Tycho project to actually build and package the editor as a web application archive (war), and the target platform on top of which to compile and build the web application. Build the web archive and deploy on Tomcat.


The current DSL Forge version is based on Eclipse Mars packages. The packages are available under To know which package is the most appropriate for you, select one of the following alternatives.


DSL Forge is a framework for the development of domain-specific language (DSL) editors for web applications and cloud IDEs. The framework makes it possible to create and edit models, launch automated tool chains on the server, including model-to-model transformations, code generation, live validation, and execution of the generated artefacts.

Generate Web Editor from Xtext

Generate a RAP editor with both client-side ANTLR Parser, and Xtext runtime features in the back-end. The Xtext/RAP Generator option produces an Eclipse plugin with the suffix “.web”. To compile the plugin, don’t forget to switch the target platform to RAP.

Generate Web Editor from ANTLR

The Generator takes as input an Xtext grammar, generates JavaScript parser and lexer, and does the wiring with an ACE Editor. As Xtext takes a subset of ANTLR while adding the integration layer for EMF, the generator ignores the extra info, and extracts the ANTLR grammar to generate the “.g” file.

Customize the Web editor

The generated code contains Java classes and JavaScript sripts; both artefacts can be customized according the developer's needs. Below some hints on how to customize the generated editors, for more advanced customizations, feel free contact the support.
