OM.Show

Utilities for showing string-like things.

Documentation

showt :: (Show a, IsString b) => a -> b

Like show, but for any string-like thing.

showj :: (ToJSON a, IsString b) => a -> b

Show the JSON representation as any kind of string-like thing. Primarily useful for dumping JSON values into log messages without having to jump through too many hoops.

newtype ShowJ a

Wrapper whose Show instance outputs JSON.

Especially useful with `-XDerivingVia` e.g.

newtype Foo = Foo SomeType
  deriving Show via (ShowJ SomeType)

This will cause @show (foo :: Foo) to output the JSON representation of SomeType.
