pd-andy/elm-web-audio/2.3.0

Renamed to hayleigh-dot-dev/elm-web-audio. It is published under that name, and new versions come out there.

Versions published as pd-andy/elm-web-audio still install under that name. 5 versions of 5 come from the new location (see their notes).

Rerouted (cache, verified). The original is gone. This copy comes from a Lamdera package cache made before it went. The Lamdera package server serves a copy recovered from a Lamdera package cache from 2021-02-13.

What we checked: Rebuilt from the unpacked sources in a Lamdera package cache (5 copies agree), which Elm only writes after the published SHA-1 checked out; elm.json is byte-identical to package.elm-lang.org's; the exposed modules match docs.json; the zip is our own, so its SHA-1 is not the published one.

The Lamdera compiler uses this copy and prints a one-line notice saying so. elm itself fails to download this version.

WebAudio.Program

Each of the functions contained in this module are wrappers for the existing Browser application types. They need just two additions to the record:

  • An audio function that takes your model and returns a WebAudio.Graph.
audio : Model -> WebAudio.Graph
audio model =
  List.map voice model.notes
  • A port to send the encoded audio graph to javascript.
port audioPort : Json.Encode.Value -> Cmd msg

With these programs, your audio function is called automatically after every update just like your view function is. So if we wanted to create a Browser.element program, we'd instead do:

main : Program () Model Msg
main =
  WebAudio.Program.element
    { init = init
    , update = update
    , audio = audio
    , view = view
    , subscriptions = subscriptions
    , audioPort = audioPort
    }

The only program from Browser not support is Browser.sandbox as those programs cannot produce Cmds and so can't call the port needed to send our audio graph to javascript.

{ init : flags -> ( model, Cmd msg )
, update : msg -> model -> ( model, Cmd msg )
, audio : model -> Graph
, view : model -> Html msg
, subscriptions : model -> Sub msg
, audioPort : Value -> Cmd msg
}
-> Program flags model msg
{ init : flags -> ( model, Cmd msg )
, update : msg -> model -> ( model, Cmd msg )
, audio : model -> Graph
, view : model -> Document msg
, subscriptions : model -> Sub msg
, audioPort : Value -> Cmd msg
}
-> Program flags model msg
{ init : flags -> Url -> Key -> ( model, Cmd msg )
, update : msg -> model -> ( model, Cmd msg )
, audio : model -> Graph
, view : model -> Document msg
, subscriptions : model -> Sub msg
, audioPort : Value -> Cmd msg
, onUrlRequest : UrlRequest -> msg
, onUrlChange : Url -> msg
}
-> Program flags model msg
{ init : flags -> ( model, Cmd msg )
, update : msg -> model -> ( model, Cmd msg )
, audio : model -> Graph
, subscriptions : model -> Sub msg
, audioPort : Value -> Cmd msg
}
-> Program flags model msg
