Hybrid Graphical-Textual DSL Editors: Vision, Requirements and Challenges

Hybrid graphical-textual domain-specific languages can deliver the best of both worlds of graphical and textual modelling: an intuitive graphical syntax for some parts of the language and a concise textual syntax for others. This paper discusses the requirements of hybrid graphical-textual domain-specific languages and their supporting editors, highlighting challenges and potential enhancements. We present our vision for future developments, aiming to simplify the process of engineering such languages and additionally, to expand their capabilities.
