The Asf+Sdf Meta-Environment provides a collection of tools for the generation of programming environments. We show how Eclipse can be extended with these generic language tools. By integrating the GUI and text editor of the Meta-Environment with Eclipse using ToolBus technology, we demonstrate the integration of third party, non-Java, software in Eclipse. By doing so, we create an experimentation framework for further programming language research. We describe our experiences and sketch future work.
