Eclipse Project Proposal

eTrice Room DSL Implementation Proposed as New Eclipse MDT Project

Jessica Thornsby

Code generators and tooling for model editing, in new implementation of the Real-Time Object Oriented Modeling DSL.

eTrice has been proposed as a new Eclipse project,
under the MDT Project.

This project aims to be an implementation of the Real-Time
Object Oriented Modeling (ROOM) DSL, alongside code generators and
tooling for model editing. Portable runtime libraries for Java and
C++ will also be provided, with a library for ANSI-C planned for
the future. Services such as messaging, thread and process creation
will also be supplied as part of the project, alongside built-in
possibilities for sequence diagram creation from the running
software. Distributed heterogenous systems will be supported out of
the box.

The ROOM metamodel will be based on EMF and the editors will be
implemented using Xtext. It is planned that additional graphical
editors for structure and behaviour will be added using GMF or
Graphiti. The code generators will be based on Xpand and Xtend.
eTrice is targeting extensibility, for example by extending the
ROOM metamodel, adding Editors, or adding new code generators for
new languages or middleware.

The initial Trice committers Thomas Schuetz and Henrik
Rentz-Reiche previously created a ROOM tool called Trice, however
this tool was created from scratch with Visual C++ and therefore it
has been decided to redo this tool completely, rather than try to
migrate it. Trice will contribute some pilot projects which can be
converted from Trice to eTrice, and patterns and howtos, but no
