Embedding of external DSLs in Scala: why and how!

Sooner or later, you'll find yourself wanting to create your own domain-specific language or embed an external DSL into your functional language of choice, i.e Scala ;). This presentation delves into the motivations behind this choice and offers practical guidance on how to achieve it. Specifically, it will demonstrate the implementation of the syntax, semantics, and type system of DSLs using the tagless-final style, along with some of the latest Scala 3 features: extension methods, Conversion type-class, match types, union types, polymorphic function types, and more. Real-world examples will be drawn from the Scala embedding of two fascinating external languages: the command-line JSON filtering language, jq, and the array programming language, q.
