Abstract
The use of domain specific languages (DSL), instead of general purpose languages introduces a number of advantages in software development even if could be problematic to maintain the DSL consistent with the evolution of the domain. Traditionally, to develop a compiler/interpreter from scratch but also to modify an existing compiler to support the novel DSL is a long and difficult task. We have developed Neverlang to simplify and speed up the development and maintenance of DSLs. The framework presented in this article not only allows to develop the syntax and the semantic of a new language from scratch but it is particularly focused on the reusability of the language definition. The interpreters/compilers produced with such a framework are modular and it is easy to add remove or modify their sections. This allows to modify the DSL definition in order to follow the evolution of the underneath domain. In this work, we explore the Neverlang framework and try out the adaptability of its language definition.
