Embed the editor in the host app:

view : Model -> Html Msg
view model =
    div [ HA.style "margin" "60px" ]
        [ ...
        , Editor.embedded config model.editor
        , ...
        ]

Initialize the embedded editor:

init : () -> ( Model, Cmd Msg )
init () =
    ( { editor = Editor.init config AppText.jabberwocky
      , ...
      }
    , Cmd.none
    )

Load text into the embedded editor.

load : WrapOption -> String -> Model -> ( Model, Cmd Msg )
load wrapOption text model =
    let
        newEditor =
            Editor.load wrapOption text model.editor
    in
    ( { model | editor = newEditor }, Cmd.none )

Respond to updates in the editor:

update : Msg -> Model -> ( Model, Cmd Msg )
update msg model =
    case msg of
        EditorMsg editorMsg ->
            let
                ( editor, cmd ) =
                    Editor.update editorMsg model.editor
            in
            ( { model | editor = editor }, Cmd.map EditorMsg cmd )


        ...

Use to insert text into the editor at a given position, e.g.,

pasteToClipboard : Model -> String -> ( Model, Cmd msg )
pasteToClipboard model editor =
    ( { model
        | editor =
            Editor.insert
                (Editor.getWrapOption model.editor)
                (Editor.getCursor model.editor)
                editor
                model.editor
      }
    , Cmd.none
    )

Embed the editor in an app like this:

type alias Model =
    { editor : Editor
    , ...
    }

A typical configuration:

config : EditorConfig Msg
config =
    { editorMsg = EditorMsg
    , sliderMsg = SliderMsg
    , editorStyle = editorStyle
    , width = 500
    , lines = 30
    , lineHeight = 16.0
    , showInfoPanel = True
    , wrapParams = { maximumWidth = 55, optimalWidth = 50, stringWidth = String.length }
    , wrapOption = DontWrap
    }

Example:

type Msg
    = EditorMsg EditorMsg
    | SliderMsg Slider.Msg
    | LogErr String
    ...

Get the cursor position. See the example for insert.

Get the options for wrapping text. See the example for insert.

        [ Sub.map SliderMsg <|
            Slider.subscriptions (Editor.slider model.editor)
          , ...

            let
                ( newEditor, cmd ) =
