Tom Schrijvers is a professor of computer science at KU Leuven in Belgium since 2014, and previously from 2011 until 2014 at Ghent University in Belgium. He has over 20 years of research experience in programming languages and has co-authored more than 100 scientific papers. Much of his research focuses on functional programming and on the Haskell programming language in particular: he has made many contributions to the language, its ecosystem and applications, and chaired academic events like the Haskell Symposium. At the same time, he has more than a decade of teaching experience (including functional programming with Haskell) and received several teaching awards.

Summary

In this chapter, we studied DSLs embedded as libraries in Haskell. We saw two examples of such embedded DSLs – one for pretty-printing source code and one for financial contracts. Both revolve around an abstract data type, several combinators to construct values of that abstract data type, and one or more interpretation functions. We also studied two implementation techniques, deep and shallow embedding, as well as a refinement of the latter (“finally tagless”) for additional flexibility.

Chapter 14, Parser Combinators, complements this chapter. It introduces another example of a DSL for parsing that has been copied from Haskell to other programming languages. Moreover, this DSL is quite useful for processing standalone DSLs with a custom syntax.
