Combining Scalaz and Shapeless for Great Good

by Lars Hupel

Published October 25, 2013 in Programming

Scalaz is an extension to the Scala standard library providing purely functional data structures and useful abstractions. Shapeless is a library for generic programming and pushes Scala’s type system quite far. Recently, there have been some developments in providing interoperability between both libraries, which turns out to be massively useful.

In this talk, I showcased some of the cool available techniques, including abstracting over heterogeneous data and the arity of functions, using macros to generate type class instances, and (de)serializing data with zero boilerplate.
