[36m-- TYPE MISMATCH ------------------------------------------------------ Main.elm[0m

The argument to function `start` is causing a mismatch.

 7│   start
 8│[31m>[0m    { model = 0
 9│[31m>[0m    , update = update
10│[31m>[0m    , view = view
11│[31m>[0m    }

Function `start` is expecting the argument to be:

    { ...
    , update : CounterList.Action -> [33mnumber[0m -> [33mnumber[0m
    , view : Signal.Address CounterList.Action -> [33mnumber[0m -> Html.Html
    }

But it is:

    { ...
    , update :
          CounterList.Action
          -> [33m{ counters : List ( CounterList.ID, Counter.Model )
          , nextID : CounterList.ID
          }[0m
          -> [33m{ counters : List ( CounterList.ID, Counter.Model )
          , nextID : CounterList.ID
          }[0m
    , view :
          Signal.Address CounterList.Action
          -> [33m{ counters : List ( CounterList.ID, Counter.Model )
          , nextID : CounterList.ID

When did you download your installer? What you observe was fixed after the initial release (on Friday, I think), and the old installers were overwritten with fixed ones.

[husio]

Few hours ago. I installed from source, using ghc and cabal. I noticed the same problem using online editor, before the website was down for good.

[jvoigtlaender]

This is the relevant commit: https://github.com/elm-lang/elm-compiler/commit/4a39fdf0a2668459d86d1e45c01b4fec4c6b4dbc.

[husio]

Cool, please close this issue if it's not relevant anymore then.

I'm using 0.16.0, which does not include this patch I guess.

[jvoigtlaender]

From source, did you install master or 0.16 branch? Maybe the commit I mention above was not backported into the 0.16 branch.

About the online editor, yes, it seems Evan forgot to update that one. See https://github.com/elm-lang/elm-lang.org/issues/427#issuecomment-158660239.

[jvoigtlaender]

I don't have the power to close this issue. You have.

[husio]

I was following elm-platform instructions, which in short is:

$ curl https://raw.githubusercontent.com/elm-lang/elm-platform/master/installers/BuildFromSource.hs > BuildFromSource.hs
$ runhaskell BuildFromSource.hs 0.16

[jvoigtlaender]

Yeah. Indeed, the fix is only in master, not in 0.16. @evancz, you probably want to move the 0.16.0 and/or 0.16 tags, because otherwise people building from source will get this buggy behavior in eternity (when installing 0.16).

[jvoigtlaender]

@husio, for the moment, you could simply do runhaskell BuildFromSource.hs master and should get a fixed version.

[jvoigtlaender]

@husio, I think you can close this issue now. Evan moved the tag, so that people installing 0.16 from source will get the fixed behavior.
