Abstract: Domain-specific languages (DSLs) are both pervasive and powerful, but remain difficult to integrate into large projects. As a result, while DSLs can bring distinct advantages in performance, reliability, and maintainability, their use often involves trading off other good software-engineering practices. In this paper, we describe an extension to the Clang C++ compiler to support syntax plugins, and we demonstrate how this mechanism allows making use of DSLs inside of a C++ code base without needing to separate the DSL source code from the surrounding C++ code.
