This is a set of utilities for the Haskell prettyrinter package. Most notable is automatic deriving of Pretty instance from the Generic instance, e.g.

{-# LANGUAGE DeriveGeneric #-}

import Prettyprinter.Generics

data Foo a b = Bar Int | Baz a b
  deriving (Generic)

instance (Pretty a, Pretty b) => Pretty (Foo a b) where
  pretty = ppGeneric

printed :: Doc ann
printed = pretty $ Baz (Bar 10 :: Foo () ()) [1..22]

which would put following into printed:
