Description
Generic show.
- class HFunctor phi f => HShow phi f where
- hShowsPrecAlg :: Algebra' phi f [Int -> ShowS]
- class Show1 f where
- showsPrec :: (Fam phi, HShow phi (PF phi)) => phi ix -> Int -> ix -> ShowS
- show :: (Fam phi, HShow phi (PF phi)) => phi ix -> ix -> String
- spaces :: [ShowS] -> ShowS
- commas :: [ShowS] -> ShowS
- intersperse :: String -> [ShowS] -> ShowS
Generic show
class HFunctor phi f => HShow phi f where Source
The list in the result type allows us to get at the fields of a constructor individually, which in turn allows us to insert additional stuff in between if record notation is used.
Methods
hShowsPrecAlg :: Algebra' phi f [Int -> ShowS] Source
Instances
| HShow phi U | |
| Show a => HShow phi (K a) | For constant types, we make use of the standard show function. |
| El phi xi => HShow phi (I xi) | |
| (Constructor c, HShow phi f) => HShow phi (C c f) | |
| (Show1 f, Traversable f, HShow phi g) => HShow phi ((:.:) f g) | |
| HShow phi f => HShow phi ((:>:) f ix) | |
| (HShow phi f, HShow phi g) => HShow phi ((:*:) f g) | |
| (HShow phi f, HShow phi g) => HShow phi ((:+:) f g) |
Utilities
intersperse :: String -> [ShowS] -> ShowS Source
