MetaBorg: Domain-specific Language Embedding and Assimilation

It is recognized that providing programmers with languages that are close to problem domain can increase productivity significantly. Creating a new full-blown language can be too expensive, therefore domain specific languages (DSL-s) are usually combined with a general purpose language (GPL). Generative programming has been shown to be useful for this kind of language extensions. This report focuses on technologies behind MetaBorg, a complete gen-erative programming solution proposed by Eelco Visser and his team. It provides means for combining syntaxes and semantics of a base GPL and DSL-s. Using the definition of combined language it creates tools for translating programs written in new language back to the base language.
