Programming Language

Rascal

Appeared 2009

Domain-specific language for metaprogramming and language-oriented programming, which includes tasks like static code analysis, program transformation, program generation, and the implementation of domain-specific languages. It serves as a general meta language without bias towards any specific software language. Rascal incorporates elements from both relational calculus and term rewriting, while its syntax and semantics are a blend of procedural (imperative) and functional programming.
