Storm: A Language Platform for Interacting and Extensible Languages (Tool Demo)

The ability to extend programming languages with domain-specific concepts is becoming an essential technology for developing complex software. However, many domain-specific languages are implemented in a way that interact poorly with the host language. There are a number of tools that aim to improve the situation by simplifying the creation of domain-specific languages, and allow easier interactions between the host language and the domain-specific language. However, many of these tools are limited to a single host language, and rarely allow extending the language used for language creation. To improve the situation, we created the language platform Storm, which aims to make the creation and usage of multiple extensible languages easy and seamless. This is accomplished by means of a shared, standardized namespace and in-process code generation, which gives Storm a high degree of extensibility, making it possible to extend or replace the built-in languages at will.
