elmlang | general | Ok. Not supported. What could be the work-around? | 2019-05-14T06:46:06.491100 | Majorie |
elmlang | general | Use Http.get, <http://Http.post|Http.post>, or Http.request | 2019-05-14T06:47:16.491900 | Danika |
elmlang | general | ok. Thank you pd-andy :slightly_smiling_face: | 2019-05-14T06:47:44.492500 | Majorie |
elmlang | general | As always, the docs will help (:
<https://package.elm-lang.org/packages/elm/http/latest/> | 2019-05-14T06:48:07.493000 | Danika |
elmlang | general | I wasnt around for 0.18 so I can’t really comment on how different the API is.
The 0.18 docs have:
```
getWarAndPeace : Cmd Msg
getWarAndPeace =
Http.send NewBook <|
Http.getString "<https://example.com/books/war-and-peace.md>”
```
Which I guess would translate to:
```
getWarAndPeace : Cmd Msg
getWarAndPea... | 2019-05-14T06:51:32.495500 | Danika |
elmlang | general | This works: sendGet : (Result Error a -> msg) -> String -> Decoder a -> Cmd Msg -- oli Cmd msg
sendGet msg theUrl theDecoder =
-- Http.get theUrl theDecoder
-- |> Http.send msg
Http.get
{ url = theUrl
, expect = Http.expectJson LoadRepos ( Decode.list repoDecoder )
... | 2019-05-14T08:03:54.496000 | Majorie |
elmlang | general | When type Msg
= UpdateQuery String
| Search
| LoadRepos (Result Http.Error (List Repo)) | 2019-05-14T08:04:29.496300 | Majorie |
elmlang | general | Can I ask a question about a weird error? I get a DOM error when compiling with "make" but it works when compiling with "make debug" | 2019-05-14T08:53:04.497300 | Kristina |
elmlang | general | What is the error | 2019-05-14T09:00:57.497600 | Danika |
elmlang | general | can it ever happen, that in `Date.now |> Task.map (Debug.log "date") |> Task.perform` the log is not triggered? I'd assume: no, but I have a case where it's like this. | 2019-05-14T09:11:28.498900 | Earnestine |
elmlang | general | I have this code in the update function | 2019-05-14T09:17:30.499000 | Kristina |
elmlang | general | The idea is that OpenNewLedgerModal creates a modal dialog. Then I want to select text in the dialog. | 2019-05-14T09:18:35.000100 | Kristina |
elmlang | general | In order to have the dialog actually exist, there's a command sending a SelectName message. | 2019-05-14T09:19:16.000800 | Kristina |
elmlang | general | That update command sends a command through a port to select the text, the element of which should now exist because Elm should hav had time to update the DOM. | 2019-05-14T09:20:18.001900 | Kristina |
elmlang | general | If I compile with "make debug" this works fine. If I compile with "make" the element does not exist. | 2019-05-14T09:20:49.002500 | Kristina |
elmlang | general | This is the code in the view function: | 2019-05-14T09:23:49.002900 | Kristina |
elmlang | general | "openNewLedgerModal" is the function that creates the dialog. | 2019-05-14T09:24:14.003500 | Kristina |
elmlang | general | <@Kristina> you need to wait for the next animation frame in JS and look for the element after that. | 2019-05-14T09:39:36.004700 | Earlean |
elmlang | general | This is the javascript snippet that does the actual selecting: | 2019-05-14T09:39:39.004800 | Kristina |
elmlang | general | Ah OK. | 2019-05-14T09:39:52.005200 | Kristina |
elmlang | general | Do you know if I still need to create a new command message for the DOM to update, or is that unnecessary? | 2019-05-14T09:41:16.005400 | Kristina |
elmlang | general | It's unnecessary | 2019-05-14T09:44:42.005600 | Earlean |
elmlang | general | :thinking_face: | 2019-05-14T09:48:09.005800 | Nana |
elmlang | general | try this:
`Date.now |> Task.map (\a -> Debug.log "date" a) |> Task.perform` | 2019-05-14T09:49:05.006000 | Nana |
elmlang | general | OK, thank you for your help. | 2019-05-14T09:50:50.006200 | Kristina |
elmlang | general | Why should this make a difference? | 2019-05-14T09:51:06.006400 | Millie |
elmlang | general | yeah nvm | 2019-05-14T09:56:01.006600 | Nana |
elmlang | general | Are you giving `Task.perform` a `(Date -> msg)` argument? Are you getting the result as a msg anywhere? | 2019-05-14T10:24:16.006800 | Rico |
elmlang | general | <https://github.com/elm-explorations/test> | 2019-05-14T12:41:18.007200 | Willodean |
elmlang | general | I think these docs are out of date | 2019-05-14T12:41:22.007400 | Willodean |
elmlang | general | A new meetup is born! Any Santa Barbarians out there? :grin:
<https://twitter.com/dillontkearns/status/1128349527700717568> | 2019-05-14T13:24:19.007900 | Sade |
elmlang | general | Actually is anyone able to get elm-test working on nixos? | 2019-05-14T13:53:03.008400 | Willodean |
elmlang | general | <@Willodean> I did get it working at some point, but I forget the exact sequence of actions. I remember installing with npm and then going to edit some file, or move the executable someplace else. memory is hazy. | 2019-05-14T14:12:05.009500 | Lindsey |
elmlang | general | there is mention of all this in the nixos bug tracker though | 2019-05-14T14:12:24.010000 | Lindsey |
elmlang | general | <@Lindsey> where? Also I think I just need to supply `binwrap-install` to `elm-test` | 2019-05-14T14:15:06.010600 | Willodean |
elmlang | general | but its not proving easy | 2019-05-14T14:15:09.010800 | Willodean |
elmlang | general | <@Willodean> sorry I can't be more specific right now, I have to run. The upshot is that `which elm-test` gives me `/home/bburdette/.npm-packages/bin/elm-test` | 2019-05-14T14:29:23.011700 | Lindsey |
elmlang | general | oh | 2019-05-14T14:29:41.011900 | Willodean |
elmlang | general | that's not going to work for me | 2019-05-14T14:29:46.012100 | Willodean |
elmlang | general | I need to run tests in the check phase of my build | 2019-05-14T14:29:55.012400 | Willodean |
elmlang | general | K, well here's the nixpkgs issue: <https://github.com/NixOS/nixpkgs/issues/45280> | 2019-05-14T14:32:52.013200 | Lindsey |
elmlang | general | I gave your API a try then. I have a data structure that represents the wires and chips on a circuit board (for a game I'm making). Currently I've written encoders and decoders for converting this to bytes and back. It involves a lot of record types and writing those using your API was quite easy to do. I didn't feel... | 2019-05-14T16:05:09.013400 | Jae |
elmlang | general | Here's all the codecs I wrote if you're curious (took about 45 minutes to do) | 2019-05-14T16:08:01.013800 | Jae |
elmlang | general | I hope this is a dumb question with a simple answer, but how do I turn a `List Json.Encode.Value` into a `Json.Encode.Value`? In 0.18.0, there was `Json.Encode.list`, but the purpose of that function was inexplicably (again, I can't find any documentation of this change in the changelogs/guides) changed. | 2019-05-14T16:11:34.016500 | Lu |
elmlang | general | there is <https://package.elm-lang.org/packages/elm/json/latest/Json-Encode#list> which is now more flexible | 2019-05-14T16:13:18.016800 | Virgie |
elmlang | general | because you supply the `a -> Value` function, but if you already have a `Value`, use `identity` as that function | 2019-05-14T16:13:45.017500 | Virgie |
elmlang | general | `identity : Value -> Value` | 2019-05-14T16:14:05.018000 | Virgie |
elmlang | general | No, I have a `List Value`, which is what `Json.Encode.list` use to accept | 2019-05-14T16:14:26.018300 | Lu |
elmlang | general | yes, so `a ~ Value` in your case | 2019-05-14T16:14:48.018900 | Virgie |
elmlang | general | no, `a` is a `List Value`. Maybe I'm missing something obvious | 2019-05-14T16:15:33.019500 | Lu |
elmlang | general | oh.... | 2019-05-14T16:15:56.019700 | Lu |
elmlang | general | I see | 2019-05-14T16:15:58.019900 | Lu |
elmlang | general | thank you | 2019-05-14T16:16:00.020100 | Lu |
elmlang | general | The big advantage of the new API is that you don't have to manually map each item in the list:
```
-- 0.18
[1, 2, 3]
|> List.map <http://Encode.int|Encode.int>
|> Encode.list
-- 0.19
[1, 2, 3]
|> Encode.list <http://Encode.int|Encode.int>
``` | 2019-05-14T16:17:53.021900 | Carman |
elmlang | general | <@Carman> for sure. that would have been nice when I originally wrote this code, but right now I'm trying to just get back to a stable compiling state | 2019-05-14T16:19:43.023500 | Lu |
elmlang | general | Then as mentioned by <@Virgie>, `Encode.list identity` behaves like the 0.18 version of the function | 2019-05-14T16:23:52.024900 | Carman |
elmlang | general | if you're trying to fix a lot of these it may be helpful to create a shim like:
```
oldListEncode : List Value -> Value
oldListEncode values =
Encode.list identity values
``` | 2019-05-14T16:24:42.025900 | Carman |
elmlang | general | good idea, thanks <@Carman> and <@Virgie> | 2019-05-14T16:25:56.026400 | Lu |
elmlang | general | Is there a good pattern for encoding a list where you may want to drop items? My current solution has to loop twice
```
Json.Encode.list identity
<| List.filterMap encodeIfInteresting things
``` | 2019-05-14T18:27:48.029400 | Lu |
elmlang | general | In my mind it doesn’t seem like it should be the decoders job to drop items | 2019-05-14T19:10:02.030900 | Danika |
elmlang | general | makes sense, thanks | 2019-05-14T19:28:01.031100 | Lu |
elmlang | general | Can someone share a discount code for Elm in Action? | 2019-05-15T02:32:30.032500 | Lory |
elmlang | general | That would be great.
P.S. I've got the coupon. | 2019-05-15T02:32:36.032700 | Lory |
elmlang | general | index.html:
<script>
var app = Elm.Main.init({ node: document.querySelector('main') })
</script>
Main.elm the functionality.
If I compile: elm make Main.elm -> large index.html overwrites existing one
How I should compile that var app is shown on html page? | 2019-05-15T02:40:35.033000 | Majorie |
elmlang | general | If you are modifying your index.html, you shouldn't compile the html file but just the javascript file
`elm make Main.elm --output=/dist/index.js` for example | 2019-05-15T02:48:11.033500 | Dexter |
elmlang | general | (And then include dist/index.js in your html file) | 2019-05-15T02:48:39.033700 | Dexter |
elmlang | general | OK. I have done that before. But I am wondering what is the idea having such (working in Ellie) line in index.html : var app = Elm.Main.init({ node: document.querySelector('main') }) | 2019-05-15T02:50:44.033900 | Majorie |
elmlang | general | because you might want to add Javascript that uses the ports you define (they will be available on `app.ports`) | 2019-05-15T02:54:13.034100 | Dexter |
elmlang | general | I think var app = Elm.Main.init({ node: document.querySelector('main') }) should some how pick up the functionality from Main.elm | 2019-05-15T02:57:39.034300 | Majorie |
elmlang | general | I should figure out how it should be compiled .. | 2019-05-15T03:05:01.034500 | Majorie |
elmlang | general | It seems like you are still concerned with something <@Majorie>, is it correct? | 2019-05-15T04:06:39.034700 | Lynne |
elmlang | general | Hi folks !
I would like to clearly identify when NOT using Elm. Could you give some concrete use cases where Elm was not suited (because of performance, ecosystem, ... whatever)? (please answer in the thread) | 2019-05-15T04:15:17.037700 | Loralee |
elmlang | general | Well, this is working: <script src="main.js"></script>
</head>
<body>
<div id="elm"></div>
<main></main>
<script>
//var app = Elm.Main.init({ node: document.querySelector('src/main') })
var app = Elm.Main.init({
node: document.getElementById... | 2019-05-15T04:16:48.037800 | Majorie |
elmlang | general | So at the moment I leave "document.querySelector .." | 2019-05-15T04:17:38.038100 | Majorie |
elmlang | general | `querySelector` is looking for nodes inside document so using it like this would not work, of course. | 2019-05-15T04:42:38.038400 | Lynne |
elmlang | general | If you have further questions or don’t understand how anything works feel free to ask | 2019-05-15T04:42:51.038600 | Lynne |
elmlang | general | Ok Thank you Sergey and Elvin ! | 2019-05-15T04:56:38.038800 | Majorie |
elmlang | general | I would (professionally) not use it in cases where I don’t build an UI for the web. I’ve seen experiments to use Elm in backend systems or even postgres triggers (<@Jin> :P). Those are nice and interesting experiments, and I really want to use Elm as much as I can, but as those things are not the current design focus o... | 2019-05-15T05:10:03.039000 | Timika |
elmlang | general | Yeah, indeed I meant "not using Elm for the front end". I'm also pretty convinced that there isn't good other place for Elm outside front end *currently*. | 2019-05-15T05:24:14.039400 | Loralee |
elmlang | general | Is there a simpler way to implement a set of radio boxes in elm? | 2019-05-15T05:45:39.039600 | Carrie |
elmlang | general | the only exception I'd make is server-side-rendering, which can be achieved by using JSDOM or headless chrome if need be, other than that it's too risky to use Elm in other environments than frontend uis | 2019-05-15T05:46:54.039700 | Denae |
elmlang | general | Simpler than what? | 2019-05-15T06:04:21.041500 | Lynne |
elmlang | general | I'd like to ask if there is a well-defined method for radio boxes. | 2019-05-15T06:06:42.043100 | Carrie |
elmlang | general | Yes, list of `input` elements with `type` `"radio"` | 2019-05-15T06:09:37.045100 | Lynne |
elmlang | general | But he doesn't have the corresponding radio function. Do I need to define it in msg? | 2019-05-15T06:13:18.048400 | Carrie |
elmlang | general | Hello. I risk repeating an earlier question by <@Daryl> about pre-loading, but I think it moves the discussion on (as well as asking a question to him in particular). There seem to be a number of strategies that people have used for preloading images: 1) A port to a javascript preloader, e.g. 'Programming Elm' and <htt... | 2019-05-15T06:15:44.049900 | Guadalupe |
elmlang | general | Sorry, I don’t understand what you mean | 2019-05-15T06:17:32.050200 | Lynne |
elmlang | general | <@Guadalupe> here's one pretty simple method I came up with: <https://ellie-app.com/5xFtMbppw64a1> (if the goal is specifically to smoothly load images) | 2019-05-15T06:21:10.051300 | Nana |
elmlang | general | That looks sweet - and no, not just for the kittens! ; thanks for sharing that | 2019-05-15T06:26:18.052200 | Guadalupe |
elmlang | general | When I chose another radio, the clicked radio was still in its original state. | 2019-05-15T06:32:13.052300 | Carrie |
elmlang | general | I see. You need to set `checked` attribute of the radio button to match the value in model | 2019-05-15T06:42:44.052700 | Lynne |
elmlang | general | For example, if you have `selectedOption` field which you update when user clicks on a button, you should add `checked (value == model.selectedOption)` where `value` is something identifying this particular button | 2019-05-15T06:44:16.052900 | Lynne |
elmlang | general | <https://ellie-app.com/5xWFVYnRQGxa1> | 2019-05-15T06:47:14.053100 | Lynne |
elmlang | general | A buddy of mine, who wrote a fair amount of Elm before deciding he didnt like it, said something to the effect of “We just re-write the front end every 8 months anyway, so investing a lot in stability and maintainability of our front end isnt worth it”. | 2019-05-15T06:48:02.053300 | Ashton |
elmlang | general | I thought that was an interesting perspective, even if I dont ultimately agree with it. | 2019-05-15T06:50:00.053500 | Ashton |
elmlang | general | It seems weird they re write ALL their codebase indeed.... it is maybe rewritten but incrementaly , no? | 2019-05-15T07:10:03.053700 | Loralee |
elmlang | general | Or is it à special "front end"? | 2019-05-15T07:10:27.053900 | Loralee |
elmlang | general | Defiantly food for thought <@Ashton> :thinking_face: | 2019-05-15T07:11:04.054100 | Timika |
elmlang | general | Thank you very much. | 2019-05-15T07:30:07.054300 | Carrie |
elmlang | general | it's also a good idea to wrap your radio buttons into something like:
`radioGroup: {options:List (a, String), onChange:a -> msg} -> Html msg` | 2019-05-15T07:53:13.054700 | Nana |
