Re: [elm-discuss] Looking for subcomponent example to learn from

Which of these elements can fire events? Is the text at the bottom the only place where the user can interact? If so, then the graphical elements up top can just be functions that take whatever data is needed to draw them. ivDrip : IvData -> Html a clock : Time -> Html a On Sat, Oct 22, 2016

Re: [elm-discuss] How to model a transient state?

What if you added a third value to the ReadState type? type ReadState = Read | Unread | Marked Then your filtered view will show both Unread and Marked. When the user refreshes, you can map all the Marked items to Read. On Thu, Oct 20, 2016 at 12:43 AM, Jacky See wrote: >

Re: [elm-discuss] How to write function that updates arbitrary element of a record

This kind of problem (access to arbitrary elements) is usually better solved by a Dict than a record. In this case, you could try something like: type NumberText = FloatText String | IntText String type alias Model = Dict Key NumberText type Msg = UpdateField Key String update : Msg -> Model

Re: [elm-discuss] why no more primes on 0.18 ?

Re: primes. Totally agree with Peter. One prime is kinda nice for a temporary variable, but beyond that... you can add a short word to your variable name, and then you won't have to do any counting! Re: backticks. Evan's explanation from elm-dev: The backtick syntax is neat, but ultimately, it

What do you find hard about learning Elm? We want Elm to be friendly to beginners. It would be helpful to hear about your experience! On Mon, Oct 17, 2016 at 9:08 AM, António Ramos wrote: > Hello guys just trying to learm Elm but its not easy. > I just found this js

Re: [elm-discuss] Updating an image in the view.

The URL can be changed dynamically, but if it doesn't change, you don't have to worry about the program re-generating the img element 30 times a second... that sort of thing gets optimized by the Virtual DOM. On Mon, Sep 26, 2016 at 8:50 PM, Nick H <falling.maso...@gmail.com> wrote: >

Re: [elm-discuss] Updating an image in the view.

If all you are doing is loading an image from a URL, why don't you use an img element? Canvas sounds like overkill. On Sun, Sep 25, 2016 at 7:16 PM, Redvers Davies wrote: > > I'm still too early in elm to know
