Abstract

The emergence of the model-driven development paradigm has revitalized interest in domain-specific languages. Embedding a DSL in a dynamic language facilitates rapid development. This article illustrates dynamic-language features and techniques that the authors found useful while developing embedded DSLs in Ruby for a model-driven development tool. For this domain, it’s possible to achieve a runtime performance comparable to existing tools while shortening development time. This article is part of a special issue on dynamically typed languages.
