elmlang | general | Thank you two!! | 2019-03-15T07:29:40.244700 | Jarod |
elmlang | general | Hello everyone, have a question regarding full dev stack.
How do you do "Web design" to Elm?
Programmers are coding interface after web designers provided raw HTML?
Thank you | 2019-03-15T11:07:08.246700 | Fay |
elmlang | general | <@Fay> I've never worked with a "web designer" that does HTML, but I would argue they can very well learn the Elm syntax for HTML too! | 2019-03-15T11:29:26.248600 | Bert |
elmlang | general | yeah if they know html and css, they can at least learn to write "static" Elm
there's also this tool that converts HTML to Elm
<https://mbylstra.github.io/html-to-elm/> | 2019-03-15T11:36:07.250400 | Nana |
elmlang | general | Actually, at my previous place our UX expert was able to implement her ideas in Elm&CSS :slightly_smiling_face: | 2019-03-15T11:41:23.251300 | Lynne |
elmlang | general | Hmm thank you | 2019-03-15T11:44:20.251700 | Fay |
elmlang | general | hello, how do i implement parallax in elm ? | 2019-03-15T15:30:18.252700 | Leopoldo |
elmlang | general | <@Leopoldo> What do you mean by parallax? Objects in distance moving slower than objects in front? | 2019-03-15T17:12:16.253900 | Florencia |
elmlang | general | Oh - I was thinking about it in gamedev terms, but you're probably talking about something like scrolling on websites :sweat_smile: that's more likely | 2019-03-15T17:12:46.254500 | Florencia |
elmlang | general | You project a line from the users approximate eye location through the screen to your object! Truncate that line at the screen surface. Or, render with webgl? | 2019-03-15T17:30:38.255600 | Lindsey |
elmlang | general | <@Leopoldo> You should be able to easily port this to elm <https://link.medium.com/VkVJECzs5U> | 2019-03-15T17:33:24.256300 | Kris |
elmlang | general | Although fairly basic, it should work | 2019-03-15T17:33:42.256700 | Kris |
elmlang | general | you can even do it with pure CSS!
<https://alligator.io/css/pure-css-parallax/> | 2019-03-15T17:43:52.256800 | Nana |
elmlang | general | has anyone implemented a scripting language in elm? I think that would be neat. | 2019-03-15T17:49:01.257400 | Lindsey |
elmlang | general | What do you mean? Like a bash dsl? | 2019-03-15T17:49:36.257800 | Kris |
elmlang | general | Like in games where there's a simple script to run the AI in npcs, or to implement a turtle drawing language | 2019-03-15T17:52:37.259000 | Lindsey |
elmlang | general | ok, thanks, | 2019-03-15T18:08:16.259700 | Leopoldo |
elmlang | general | I will be soon | 2019-03-15T18:26:19.260300 | Danika |
elmlang | general | Is there something else aside of `Float` I can use to calculate with? | 2019-03-16T04:07:17.261800 | Salvador |
elmlang | general | I need to round a number to 2 decimal digits. so I do
```
number = 561.295
round (number *100) |> modBy 100
```
this should give me `30`, but I get `29`… because `number*100 /= 56129.5`, but `561129.4999999999`. | 2019-03-16T04:10:30.264100 | Salvador |
elmlang | general | Sounds like <https://package.elm-lang.org/packages/myrho/elm-round/latest/> could do the job. | 2019-03-16T04:38:05.264700 | Jin |
elmlang | general | There's a decimal package you could use: <https://package.elm-lang.org/packages/prikhi/decimal/latest/Decimal#round> | 2019-03-16T06:44:08.264900 | Earnest |
elmlang | general | elm-round is very nice. It rounds using strings I believe, so it doesn’t have those issues | 2019-03-16T07:00:51.266200 | Bebe |
elmlang | general | It would be very useful to have something
Iike the JS Number.prototype.toFixed in Basics at some point. I end up installing elm-round in most elm apps | 2019-03-16T07:02:47.268400 | Bebe |
elmlang | general | are the debug tools gone from elm reactor? | 2019-03-16T07:48:00.268700 | Marlys |
elmlang | general | there is currently a bug when `--debug` is enabled that crashes the compiler | 2019-03-16T07:48:29.269100 | Virgie |
elmlang | general | so I think it might be discouraged/hard to find info about it. | 2019-03-16T07:49:07.269500 | Virgie |
elmlang | general | there was this small window where I could introspect all previous executed actions | 2019-03-16T07:49:14.269800 | Marlys |
elmlang | general | yes, use `elm make --debug src/Main.elm` (or similar) to get that. but for many applications this will crash the compiler | 2019-03-16T07:50:01.270300 | Virgie |
elmlang | general | I mean with the "elm reactor" | 2019-03-16T07:51:12.271200 | Marlys |
elmlang | general | not sure, if you really wanted to you could do something like `elm make --debug src/Main.elm --output=index.html`, then open `index.html` with `elm reactor` | 2019-03-16T07:55:02.272000 | Virgie |
elmlang | general | Thank you, I'll try it out | 2019-03-16T07:55:44.272500 | Marlys |
elmlang | general | <@Marlys> you could use a build manager like parcel or, if you don’t have any external dependencies, you could use `elm-live` (for example `elm-live src/Main.elm -- --debug`) | 2019-03-16T09:15:39.273700 | Maida |
elmlang | general | I was wondering - is it possible to use elm with a different renderer, outside of the Browser? I'm thinking of using it to bind to GTK (via yue for example) or something like that | 2019-03-16T12:00:28.275200 | Elden |
elmlang | general | Not officially supported, yes-ish in theory | 2019-03-16T12:13:51.275600 | Kris |
elmlang | general | But it means that you'd've to reimplement a lot of things like virtual dom and else, I believe | 2019-03-16T12:14:53.276700 | Kris |
elmlang | general | are there any other renderers than the Browser available? | 2019-03-16T12:26:20.277200 | Elden |
elmlang | general | Do I need to decode the Event object (<https://developer.mozilla.org/en-US/docs/Web/API/Event>) when subscribing to Browser.Events? | 2019-03-16T15:05:35.278900 | Marlys |
elmlang | general | Folks who develop with webpack, do you have hot module replacement set up and working accross all your elm files? I'm for some reason unable to get any file except `Main.elm` to reload / recompile while developing | 2019-03-16T16:56:13.280600 | Al |
elmlang | general | Yes, if you are writing your own event handler | 2019-03-16T17:04:05.280700 | Lynne |
elmlang | general | Works for me in any file | 2019-03-16T17:04:28.280900 | Lynne |
elmlang | general | I had some problems using webpack HMR plugin. Try using parcel js instead. HMR works there out of the box. | 2019-03-16T17:07:54.281100 | Arlinda |
elmlang | general | I'm using elm-live and it works flawlessly so far | 2019-03-16T17:21:05.281300 | Marlys |
elmlang | general | using create-elm-app on a 10k line app and no issues. You can copy the config from their repo | 2019-03-16T17:49:47.281600 | Teri |
elmlang | general | So in the Browser.Events doc there is this note: "Unsubscribe if you do not need these events!". Is there a specific way to unsubscribe or is it enough if my Msg changes and I'm not accessing the branch where the event listener is? | 2019-03-16T18:14:25.283000 | Marlys |
elmlang | general | Unsubscribe means "no longer return the subscription from your `subscriptions` function" | 2019-03-16T18:17:00.283100 | Huong |
elmlang | general | That way, the related event listener is actually removed from the document, completely :slightly_smiling_face: | 2019-03-16T18:17:28.283300 | Huong |
elmlang | general | remember that `subscriptions : Model -> Sub Msg`, so you can decide - based on the state of your application - whether you should be subscribing to some event | 2019-03-16T18:18:04.283500 | Huong |
elmlang | general | (the subscriptions are always checked right after your `update` runs) | 2019-03-16T18:18:23.283700 | Huong |
elmlang | general | I see. Thanks! | 2019-03-16T18:22:54.283900 | Marlys |
elmlang | general | There are not, and I think for good reason. Elm focuses on the Browser as a platform and that has led the ecosystem to become very well suited to that task over the years. | 2019-03-16T20:43:09.284200 | Mozella |
elmlang | general | This is talked about as part of this talk here <https://www.youtube.com/watch?v=o_4EX4dPppA> | 2019-03-16T20:43:35.284400 | Mozella |
elmlang | general | i love watching elm vids with richard feldman. | 2019-03-16T22:50:36.285300 | Lupita |
elmlang | general | Are unused record fields removed with DCE? | 2019-03-17T07:09:57.286100 | Frieda |
elmlang | general | No | 2019-03-17T07:27:28.287100 | Huong |
elmlang | general | How do you have an 'unused record field'? | 2019-03-17T07:55:37.288000 | Earlean |
elmlang | general | only written to, never read? | 2019-03-17T07:58:46.288300 | Virgie |
elmlang | general | the problem is of course is that assigning will evaluate the thing you assign it to | 2019-03-17T07:59:16.288800 | Virgie |
elmlang | general | But, in release mode where all functions are pure, there is no way to know so in theory I think you could remove record fields that are never read | 2019-03-17T08:00:09.289600 | Virgie |
elmlang | general | but I don't think the benefit is that high; record fields are renamed to be as short as possible anyway, unlikely that removing them completely has a large effect | 2019-03-17T08:01:13.290600 | Virgie |
elmlang | general | is it possible to destructure model properties while retaining the model reference? | 2019-03-17T09:21:59.292400 | Marlys |
elmlang | general | foo model@{prop1, prop2} <- something like that? | 2019-03-17T09:22:21.293000 | Marlys |
elmlang | general | ```
let
({prop1, prop2} as foo) = computeIt ...
``` | 2019-03-17T09:24:28.293700 | Dede |
elmlang | general | cool thanks | 2019-03-17T09:24:43.294200 | Marlys |
elmlang | general | And if your record is contained in a custom type with a single constructor you can also restructure that directly.
```
let
((Bar {prop1, prop2} as foo) as bar) = computeIt ...
``` | 2019-03-17T09:27:28.297200 | Jin |
elmlang | general | even cooler, awesome! | 2019-03-17T09:28:38.297500 | Marlys |
elmlang | general | this is what I have in init
```
WebSocket.makeOpen (Debug.log "url" <| SocketHelpers.mkSocketUrl host)
|> Debug.log "makeOpen"
|> WebSocket.send PortFunnels.cmdPort
``` | 2019-03-17T14:04:19.297800 | Lynn |
elmlang | general | which leads to | 2019-03-17T14:05:09.298000 | Lynn |
elmlang | general | None | 2019-03-17T14:05:13.298200 | Lynn |
elmlang | general | Ok, so I think i can see some progress now | 2019-03-17T14:23:16.298600 | Lynn |
elmlang | general | How do I report abuse for a user on the Elm slack group? | 2019-03-17T15:20:27.299600 | Nancey |
elmlang | general | <@Nancey> try at <#C3FKL0A8H|admin-help> | 2019-03-17T15:22:56.300200 | Kris |
elmlang | general | Thanks! | 2019-03-17T15:23:17.300500 | Nancey |
elmlang | general | How can I remove an element from the DOM?
```
case ( dragState, dragItem ) of
( Moving, Just item ) ->
rectangle item.width item.height x y
( _, _ ) ->
div [] []
```
I want a new rectangle each time I hit the first catch block and dispose it otherwise. Right now, I'm getting a copy of the last rectangle when re-entering ( Moving, Just item ) but instead I want a new rectangle. | 2019-03-17T16:43:23.303300 | Marlys |
elmlang | general | You just don’t return it from your function | 2019-03-17T16:44:42.303800 | Kris |
elmlang | general | Elm takes care of rerendering stuff automatically | 2019-03-17T16:44:55.304300 | Kris |
elmlang | general | Hey ya'll, does anyone know how to set up vscode-elm to work with a WSL installation of elm? Is it even possible or should I just install elm in windows? The only reason I started using windows as a development environment is WSL, so I'd rather not go down that path | 2019-03-17T16:54:59.304600 | Annamarie |
elmlang | general | <@Kris> I don't understand | 2019-03-17T16:56:49.305000 | Marlys |
elmlang | general | I'm setting the dragItem to Nothing in between Msgs and create a new one. My intuition was that a new element will be added to the DOM. | 2019-03-17T16:59:20.306400 | Marlys |
elmlang | general | Where does this `rectangle` come from? | 2019-03-17T17:04:00.307600 | Kris |
elmlang | general | it's a function that returns a div | 2019-03-17T17:04:23.308300 | Marlys |
elmlang | general | To clarify, just *calling* a function that returns some `Html msg` won't place that in the dom, you have to put that somewhere in your view | 2019-03-17T17:04:40.308700 | Kris |
elmlang | general | If that's not what you're asking, perhaps you can setup an ellie example so I can understand better | 2019-03-17T17:05:49.310400 | Kris |
elmlang | general | yes I'll do that | 2019-03-17T17:05:59.310600 | Marlys |
elmlang | general | Who do i talk to to discuss pull requests for the elm package manager? | 2019-03-17T17:14:35.311500 | Isaias |
elmlang | general | <@Isaias> Probably <#C13L7S5GR|elm-dev> or <#C2QPJLU2X|elm-discuss> | 2019-03-17T17:16:54.312000 | Kris |
elmlang | general | Bump: anybody know how to configure vscode-elm to work with WSL? | 2019-03-17T20:00:21.312600 | Annamarie |
elmlang | general | I’m working on two different Elm projects in parallel. And after one project is compiled the second one could not be compiled. It always gives following error.
```
-- error: CORRUPT BINARY - /Users/akoppela/.elm/0.19.0/package/ContaSystemer/elm-menu/1.0.0/objs.dat:1
The binary data at
/Users/akoppela/.elm/0.19.0/package/ContaSystemer/elm-menu/1.0.0/objs.dat is
corrupt.
Elm caches build artifacts in the following directories:
/Users/akoppela/.elm
elm-stuff/
Maybe you recently installed a command line tool or editor plugin that messes
with them? They definitely should not be doing that, but you never know! So
maybe try deleting them? Everything will be rebuilt from scratch. This may help
reveal the corrupting influence.
``` | 2019-03-17T23:13:37.313900 | Frieda |
elmlang | general | So I have to clean Elm stuff every time I switch projects. If anyone experience the same thing? | 2019-03-17T23:14:08.314600 | Frieda |
elmlang | general | It happens to me each time I switch between running Elm in Webpack or the CLI | 2019-03-18T00:20:30.315200 | Carrol |
elmlang | general | Are there any resources for teaching Elm as first language?
Or anyone who has some real-world experience teaching Elm as first language? | 2019-03-18T04:16:34.316100 | Monte |
elmlang | general | <@Dorsey> did <http://software.garden> just recently. There is also <http://outreach.mcmaster.ca>. They used the old Graphics package do teach programming to kids, then switched to a cutom package using SVG. You might find some information in here <https://package.elm-lang.org/packages/MacCASOutreach/graphicsvg/latest/> | 2019-03-18T04:24:12.316800 | Jin |
elmlang | general | Thanks, awesome! =D | 2019-03-18T04:24:56.317100 | Monte |
elmlang | general | Yup, you can talk to us (me and <@Ayesha>). We just did first run a week ago. It went better than expected :smile: | 2019-03-18T04:26:40.319400 | Dorsey |
elmlang | general | <@Jin> thanks for mentioning us :heart: | 2019-03-18T04:27:27.320200 | Dorsey |
elmlang | general | (I knew you were not alone, but I forgot <@Ayesha>’s name.) | 2019-03-18T04:27:27.320400 | Jin |
elmlang | general | I don't think my friend can invest 500 EUR, but I'm reading all the posted info :smiley: | 2019-03-18T04:27:46.320900 | Monte |
elmlang | general | Also <@Virgie> and <@Danilo> helped us. | 2019-03-18T04:28:30.321900 | Dorsey |
elmlang | general | You are welcome to the materials. We also offer one on one couching. You can DM us about it. | 2019-03-18T04:29:52.323600 | Dorsey |
elmlang | general | Cool thanks! | 2019-03-18T04:30:56.323800 | Monte |
