Usability heuristics for domain-specific languages (DSLs)

Abstract

The usability of Domain-Specific Languages (DSLs) has been attracting considerable interest from researchers lately. In particular, our literature review found many usability studies that make use of subjective and empirical methods. However, we noted a lack of heuristic methods in the literature. In comparison, there exist several usability studies of Application Programming Interfaces (APIs) that have used heuristics with success, so we argue that this approach would be also useful for DSLs. Therefore, this paper proposes a set of usability heuristics for DSLs and illustrates the approach with a case study. We show how our heuristics helped us identify many actual usability problems, even for a simple DSL.
