Is it wrong for Cmds to contain functions (as opposed to data within
constructors)? If it is a reasonable practice, it would allow for more
functional component-like modules, but does this violate the Elm
architecture? If it does, is it explicitly mentioned in the docs -- I
don't remember seeing it. Here's http://elm-lang.org/examples/buttons
rewritten in the Cmd-contains-functions style. Thank you!
module Main exposing (..)
import Html exposing (beginnerProgram, div, button, text)
import Html.Events exposing (onClick)
main =
beginnerProgram { model = 0, view = view, update = update }
type Msg
= Transform (Int -> Int)
view model =
div []
[ button [ onClick (Transform ((+) -1)) ] [ text "-" ]
, div [] [ text (toString model) ]
, button [ onClick (Transform ((+) 1)) ] [ text "+" ]
]
update msg model =
case msg of
Transform xform ->
xform model
