[elm-discuss] Re: How do you test a TEA `update` function?

I've often worried about the commands bit. For the view side, you need to test that you are deriving the right data to render, while it is Evan that needs to test that, given certain data, expected DOM elements get produced? On Monday, 7 November 2016 07:44:36 UTC+1, Francesco Orsenigo wrote: >

[elm-discuss] How do you test a TEA `update` function?

How do you write unit tests to ensure that an `update : Msg -> Model -> ( Model, Cmd Msg )` function is producing the correct commands? What if the function is supposed to produce several commands batched together? Same thing for a `view : Model -> Html Msg`. Suppose I want to test whether,

[elm-discuss] Probably a *very* basic question ...

Help! This is driving me crazy ... I have Python/flask at the back end, Elm at front. The landing page is, say, http://localhost:5000. My Html.App.program is set up with an init Cmd wrapped around a Http.get decoderA "localhost:5000/initialData" of back-end data, . That works fine,

Re: [elm-discuss] Animation not very smooth.

Glad you were able to find a solution! Elm WebGL support is primitive and unofficial. If you run into performance issues, the culprit is probably the elm-webgl package and not the underlying language/platform. On Sun, Nov 6, 2016 at 4:56 AM, Gaëtan André wrote: > OK I

[elm-discuss] Re: Convincing my team that Elm isn't just going to die like CoffeeScript

CoffeeScript and Elm address two vastly different problems. CoffeeScript addressed "Writing JS is a pain in the ass": it was syntactic sugar and the need for it drastically lessened with ES6. CS was killed by the new JS extensions. Elm addresses run time errors and JS Fatigue, neither of which

Thanks, Richard & Simon. @Richard - if I try to port your code to 0.17, how easy or difficult might that be? I'm running into various not-yet-documented 0.18 changes e.g. in Task.perform. On Thursday, November 3, 2016 at 11:55:18 AM UTC-5, Richard Feldman wrote: > > I have a proof of concept

Re: [elm-discuss] Animation not very smooth.

OK I solved my problem. Culling foodElements (little green circles) to the screen led to less webgl calls which solved the smoothness problem. Webgl api calls are costly. Maybe a a way to reduce the number of calls in my case could have been to use a geometry shader to instantiate multiple

[elm-discuss] Fetch an element in a list from a parent module and render it in a child module

Hi there, is there a way for a parent module to "subscribe" to a child module "event"? Here is the thing : I want to create a contact list. For that, I have a component named ContactList. Inside, I display all contacts like this : renderContact: Contact.Model -> Html a renderContact contact =
