Applying Self-Extension Mechanism to DSLs for Establishing Model Libraries
summary
Proposes a model-level self-extension for DSLs that lets modelers define reusable components, import them, and generate HTML, CSS and TypeScript without changing the base grammar or generator. Implements the idea in a MontiCore-based GUIDSL: components are declared, instantiated with an add sign, packaged as a JAR with model, generated sources and symbol table, and reused across projects. Reimplemented parts of the Makoko front end at RWTH, showing fewer language changes, packaged reuse, and practical success in an operational system.
