Abstract syntax driven approach for language composition

Abstract

Abstract Popularity of domain-specific languages brings the problem of language components reuse. It should be possible to use parts of different languages in development of new one to lower costs and also allow incremental development. This problem could be solved using the composition of languages. In this paper we discuss the view of language composition from the perspective of concepts composition, where the role of concrete syntax is lowered. We present examples of language composition based on the principles of object composition implemented using YAJCo parser generator, that allows to specify the language based on its abstract syntax.
