Domain-specific languages in few steps : the Neverlang approach

Often an ad hoc programming language integrating features from different programming languages and paradigms represents the best choice to express a concise and clean solution to a problem. But, developing a programming language is not an easy task and this often discourages from developing your problem-oriented or domain-specific language. To foster DSL development and to favor clean and concise problem-oriented solutions we developed Neverlang. The Neverlang framework provides a mechanism to build custom programming languages up from features coming from different languages. The composability and flexibility provided by Neverlang permit to develop a new programming language by simply composing features from previously developed languages and reusing the corresponding support code (parsers, code generators, ...). In this work, we explore the Neverlang framework and try out its benefits in a case study that merges functional programming à la Python with coordination for distributed programming as in Linda.
