Software Language Engineering (SLE) is concerned with the principled techniques and concepts for the construction of software languages. In this tutorial we will explore how the Rascal metaprogramming environment and language workbench addresses aspects of implementing software languages. We will work on a simple DSL for defining questionnaires, called QL, touching upon syntax definition, static analysis, transformation, language extension, and code generation.
