HasPrettyConfig (Sole config) configDefined in prettyprinter-configurable-1.36.0.0 · Text.PrettyBy.Fixity
It's not possible to have HasPrettyConfig config config, because that would mean that every environment is a pretty-printing config on its own, which doesn't make sense. We could have an OVERLAPPABLE instance, but I'd rather not.

typetype MonadPretty config env (m :: Type -> Type) = (MonadReader env m, HasPrettyConfig env config)

A constraint for "m is a monad that allows to pretty-print values in it by a config".

Pretty-print a value in a configurable way in a monad holding a config.

valuedisplayM
