Hi, I am getting a compiler error that does not make sense to me - can
anyone help to explain why this fails to compile?
The following code:
type Message = Good | Bad | ManyOthers
type alias Node = { message : Message }
trymatch : Node -> Message -> Bool
trymatch node messageParam =
case
I'm trying to render an html select from a Dict in Elm 0.18, and the
compiler complains because Html Msg is not appendable:
12| html ++ ( option [ value ( toString key ) ] [ text val ]
^^
(++) is expecting the right side to be a:
appendable
But the

Fixed - the correct solution is:
import Http exposing ( .. )
httpErrorString : Http.Error -> String
httpErrorString error =
case error of
Http.BadStatus ( response ) ->
"bad status [" ++ response.body ++ "]"
For anyone else confused, the problem is a misunderstanding of
I'm using Elm 0.18 and trying to convert http errors into strings.
The simple module below:
import Http exposing ( .. )
httpErrorString : Http.Error -> String
httpErrorString error =
case error of
Http.BadStatus ( Response response ) ->
"bad status [" ++ response ++ "]"
