Haskell's Show Class in Isabelle/HOL

Abstract

We implemented a type class for "to-string" functions, similar to Haskell's Show class. Moreover, we provide instantiations for Isabelle/HOL's standard types like bool, prod, sum, nats, ints, and rats. It is further possible, to automatically derive show functions for arbitrary user defined datatypes similar to Haskell's "deriving Show".
