QUESTION
Thanks for the answers of my other quesion - How to write a Heterogeneous list on HList? , I could start using HList: Heterogeneous lists, mostly with API of https://hackage.haskell.org/package/HList-0.5.2.0/docs/Data-HList-HList.html
Now, I want - producing homogenous lists as HList l -> [e]
hMapOut :: forall f e l. HMapOut f l e => f -> HList l -> [e]
I've been trying create my own proof of concept code, but don't know how to do it properly.
...ANSWER
Answered 2022-Mar-03 at 10:04Your second version, flag :: ∀ t a. Foldable t => t a -> Bool
, is sensible. But mapping this over a HList is a bit tricky because the constraint doesn't have the form Type -> Constraint
, instead it's the application of t
with a (Type -> Type) -> Constraint
.
Since you don't seem to require supporting generic foldable containers (and FWIW the Foldable
-based definition of length
is a bit dubious anyway) I'd suggest instead using the IsList
class:
