Domain‐specific languages (DSLs) assist a software developer (or end‐user) in writing a program using idioms that are similar to the abstractions found in a specific problem domain. Tool support for DSLs is lacking when compared with the capabilities provided for standard general‐purpose languages (GPLs), such as Java and C++. For example, support for debugging a program written in a DSL is often non‐existent. The lack of a debugger at the proper abstraction level limits an end‐user's ability to discover and locate faults in a DSL program. This paper describes a grammar‐driven technique to build a debugging tool generation framework from existing DSL grammars. The DSL grammars are used to generate the hooks needed to interface with a supporting infrastructure constructed for an integrated development environment that assists in debugging a program written in a DSL. The contribution represents a coordinated approach to bring essential software tools (e.g. debuggers) to different types of DSLs (e.g. imperative, declarative, and hybrid). This approach hides from the end‐users the accidental complexities associated with expanding the focus of a language environment to include debuggers. The research described in this paper addresses a long‐term goal of empowering end‐users with development tools for particular DSL problem domains at the proper level of abstraction without depending on a specific GPL.
