Re: [elm-discuss] In
Nothing except when paired with a let. You do let x = foo y = bar ... in baz This let's you break up large expressions, and avoid recomputing values that are used more than once.

[elm-discuss] In 0.17, what's the analog of Mouse.click for touch devices (ie. iPhone)
I've re-written the GUI for my bridge playing app (www.deepfinesse.com) in Elm and love it! I've developed it using evanc/elm-graphics (so Collage and Element) as opposed to HTML / SVG. Back in 0.16, I thought I saw a "touch" or maybe "tap" module which I assumed I'd be using for running the app on touch devices like smart phones (a very important direction for my new app). The new app runs great on my MAC browser. I use Mouse.clicks to process human interaction. Works great. But the app is unresponsive on iPhone, no doubt because there is no mouse. But I no longer see a "touch" module to make this work on iPhones. Hopefully I'm just being blind. How does one make elm-graphics based apps work on touch devices? --bill -- You received this message because you are subscribed to the Google Groups "Elm Discuss" group.

The touch module was removed in 0.17 :-/ and there still isn't an equivalent as far as I know.

[elm-discuss] In a select element, how do I designate the initially selected option from my model?
Let's say I have a select element to choose a person, and I want to have a certain person, say with id = 3, to be initially selected. How do I pass this id down into my options, and then set the selected attribute to True in that options? Some sample code: personSelect : List Person -> String -> Html Msg personSelect : personList selectedId = div [] [ select [] (List.map personOption personList) ] personOption : Person -> Html Msg personOption : person = option [ value (toString person.id) ] [ text person.name ] Specifically, how do I get "selectedId" passed to "personOption"? Can I even do this using List.map? Thanks very much! -- You received this message because you are subscribed to the Google Groups "Elm Discuss" group.

What immediately springs to mind: personSelect : List Person -> String -> Html MsgpersonSelect personList selectedId = div [] [ select [] (List.map (personOption selectedId) personList) ] personOption : String -> Person -> Html MsgpersonOption selectedId person = ... use selctedId here now ... option [ value (toString person.id) ] [ text person.name ] 2016-08-23 7:04 GMT+02:00 Gabe Krambs : > Let's say I have a select element to choose a person, and I want to have a > certain person, say with id = 3, to be initially selected.
