Readme for prettyprinter-combinators-0.1.3
[back to package description]
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:
Baz
Bar 10
