Context Domain-level feedback Demo Conclusion (Domain-level) interactive debugging Many existing approaches to define Domain Specific Languages (DSLs) with execution semantics. Enable the use of interactive debugging (ie. breakpoints, step into, etc.) to understand and investigate defects. Two main kinds of DSLs to consider: – interpreted DSLs (with operational semantics) – compiled DSLs (with translational semantics) Erwan Bousse, Tanja Mayerhofer, Manuel Wimmer Domain-Level Debugging for Compiled DSLs 3/8

Context Domain-level feedback Demo Conclusion Problem How to provide domain-level interactive debugging when executing models conforming to compiled DLSs? Idea At runtime, automatically translate on-the-fly target states and steps into source states and steps, which can then be observed by domain-level tools.
