Description

From @aryairani in slack:

Maybe let’s open a ticket to the effect of “things I would contribute to unisonbase if there was a way to contribute to things to unisonbase”, and then list List.filter and anything else you think of.

Ideas for contributions:

base

  • ignore : a -> ()

  • void : (a ->{e} b) -> a ->{e} () (see https://github.com/unisonweb/base/issues/8; contributed, but not added to base yet)

  • repeat : Nat -> '{e} a ->{e} ()

  • forever : '{e} a ->{e} b

  • force : '{e} a ->{e} a

  • ability Ask a where ask : a

    • provide : a -> Request (Ask a) r -> r

  • ability Stream a where emit : a -> ()

    • toList
    • fromList
    • from : Nat ->{Stream Nat} a
    • range : Nat -> Nat ->{Stream Nat} ()
    • pipe
    • take
    • drop
    • takeWhile
    • dropWhile
    • terminated
    • map
    • filter
    • foldLeft

  • ability Store a where get : a ; put : a -> ()

    • store : a -> Request (Store a) r -> r

  • ability Show a where show : a -> Text?

    • Int./Nat./Boolean./etc.show : Request (Show a) v -> v

base.List

  • filter
  • group
  • groupBy
  • indexedMap
