Engineering Hybrid Graphical-Textual Languages with Sirius and Xtext: Requirements and Challenges

Embedding textual domain specific languages into graphical modelling workbenches can help deliver the best of both worlds. In this paper, we discuss common requirements for hybrid textual/graphical modelling workbenches, and we present requirements, existing approaches and open challenges for integrating graphical editors implemented using the state-of-the-art Sirius graphical modelling framework, and textual editors developed with Xtext within the Eclipse Modeling ecosystem.
