Toward Intelligent Generation of Tailored Graphical Concrete Syntax

In model-driven engineering, the concrete syntax of a domain-specific modeling language (DSML) is fundamental as it constitutes the primary point of interaction between the user and the DSML. Nevertheless, the conventional one-size-fits-all approach to concrete syntax often undermines the effectiveness of DSMLs, as it fails to accommodate the diverse constraints and specific requirements inherent to diverse users and usage contexts. Such shortcomings can lead to a significant decline in the performance, usability, and efficiency of DSMLs. This vision paper proposes a conceptual framework to generate concrete syntax intelligently. Our framework considers multiple concerns of users and aims to align the concrete syntax with the context of the DSML usage. Additionally, we detail a baseline process to employ our framework in practice, leveraging large language models to expedite the generation of tailored concrete syntax. We illustrate the potential of our vision with two concrete examples and discuss the shortcomings and research challenges of current intelligent generation techniques.
