In Model-Driven Engineering, a number of external Domain-Specific Languages (DSL) for model manipulation have been proposed. However, they require users to learn new lan-guages that, together with their execution performance, us-ability and tool support limitations, can significantly con

a software product line configuration DSL using Ruby and Python as host languages. In summary, the proposed process and patterns facilitate the successful planning and developing of internal DSLs using dynamic programming languages as the host. Keywords-domain-specific languages I.

A great part of software development challenges can be solved by one universal tool: Abstraction. Developers solve development challenges by using expressions and concepts that abstract from too technical details. One especially supportive tool for abstraction are domain-specific languages (DSLs

Abstract. Model manipulation environments automate model opera-tions such as model consistency checking and model transformation. A number of external model manipulation Domain-Specific Languages (DSL) have been proposed, in particular for the Eclipse Modeling Frame-work (EMF). While their higher

Dynamic programming languages offer an infrastructure for the construction of in-ternal domain-specific languages (DSL). DSLs inherit the facilities of their host language such as the availability of libraries, frameworks, tool support, and other DSLs. When de-veloping an internal DSL

be remedied with the help of domain specific languages. In our case, we consider internal domain specific languages, which are based on an existing programming language. The following report details our motivation, research steps and current findings.

Domain-specific languages (DSLs) are languages tailored to a specific application domain.
