elmlang | general | the compiler error message says this as well | 2019-02-17T04:21:47.624800 | Iona |
elmlang | general | it didnt worked out. <https://gist.github.com/afidegnum/57a63d81f0273e52f6a858282c573734#file-main-elm-L458> | 2019-02-17T04:30:08.625000 | Leopoldo |
elmlang | general | Do we have any mitigation strategies for the error `elm: Map.!: given key is not an element in the map` when using the webpack / rollup loader for elm modules? I found <https://github.com/elm/compiler/issues/1851> but I have not found a workaround to this problem. | 2019-02-17T04:37:34.626300 | Moshe |
elmlang | general | this is what i have done and the new error
<https://gist.github.com/afidegnum/76daeb299a593dd4bd4ab9b3e79b165b#file-main-elm-L454-L463>
``` I am having trouble with this (::) operator:
457|> (text page.title
458|> :: (List.map (viewLinkOrText currentRoute)
459|> [ (ReadPage page.id, "Read", (String.fromInt page.id))
460|> , (EditPage page.id, "Edit", (String.fromInt page.id))
461|> , (PageDelete page.id, "Delete", (String.fromInt page.id))
462|> ] )
The left side of (::) is:
Html.Html msg
But you are trying to put that into a list filled with:
String -> String -> Html.Html msg
Lists need ALL elements to be the same type though.
-- TYPE MISMATCH -------------------------------------------------- src/Main.elm
The 2nd argument to `map` is not what I expect:
458| :: (List.map (viewLinkOrText currentRoute)
459|> [ (ReadPage page.id, "Read", (String.fromInt page.id))
460|> , (EditPage page.id, "Edit", (String.fromInt page.id))
461|> , (PageDelete page.id, "Delete", (String.fromInt page.id))
462|> ] )
This argument is a list of type:
List ( Route, String, String )
But `map` needs the 2nd argument to be:
List Route
-- TYPE MISMATCH -------------------------------------------------- src/Main.elm
The 3rd element of this list does not match all the previous elements:
213| [ UP.map ListPage <http://UP.top|UP.top>
214| , UP.map AddPage (UP.s "add")
215|> , UP.map ReadPage (UP.s "id") -- page id
216| , UP.map EditPage (UP.s "edit") -- Page id
217| ]
This `map` call produces:
UP.Parser ((PageId -> Route) -> c) c
But all the previous elements in the list are:
UP.Parser (Route -> c) c

elmlang | general | <@Moshe> I think there are two major workarounds: do not use the `--debug` flag and build compiler from forked repo where this bug is fixed as a temporary solution | 2019-02-17T04:45:59.627900 | Lynne |
elmlang | general | There is a PR: <https://github.com/elm/compiler/pull/1850> and the respective repo: <https://github.com/tomstejskal/compiler> | 2019-02-17T04:48:10.628300 | Lynne |
elmlang | general | In PR there are instructions on how to build it | 2019-02-17T04:48:19.628600 | Lynne |
elmlang | general | <@Lynne> hi, can you please lend a hand ? | 2019-02-17T04:48:48.629000 | Leopoldo |
elmlang | general | <@Lynne> awesome! Thanks for the links. | 2019-02-17T04:57:18.629800 | Moshe |
elmlang | general | <@Leopoldo> You are trying to `cons` / `::` a new element to a list. The element is a `Html msg` and the compiler is complaining the other elements in the list are `String -> String -> Html msg`.
This tells us, that the function `viewLinkOrText` is expecting other arguments than what you are handing over.
In your case the function `viewLinkOrText` would need the function signature `viewLinkOrText : Route -> (Route, String, String) -> Html msg` to fullfil your contract.
So either: you change the function signature of `viewLinkOrText`, or you build a helper function that takes a triplet of `(Route, String, String)` and calls your `viewLinkOrText` function with the unwrapped parameters. :slightly_smiling_face: | 2019-02-17T05:05:54.629900 | Moshe |
elmlang | general | hi | 2019-02-17T06:43:50.636500 | Leopoldo |
elmlang | general | I’m having the ports undefined problem in a mini-project. I believe this is because I must declare AND use a port in the Elm code? | 2019-02-17T07:45:56.637300 | Vilma |
elmlang | general | <@Vilma> if you don't use a port the compiler will consider it dead code and remove it | 2019-02-17T07:48:54.637800 | Earlean |
elmlang | general | yes I read about that | 2019-02-17T07:49:06.638100 | Vilma |
elmlang | general | just now in the forum | 2019-02-17T07:49:20.638600 | Vilma |
elmlang | general | so I must call the port function in the Elm code? | 2019-02-17T07:49:33.638900 | Vilma |
elmlang | general | also is that a bug? :thinking_face: | 2019-02-17T07:49:39.639100 | Vilma |
elmlang | general | It's intentional | 2019-02-17T07:49:57.639500 | Earlean |
elmlang | general | if it's an outgoing port then you'll need to have some code that sends to it, if it's an incoming port then you'll need to subscribe to it in your `subscriptions` function | 2019-02-17T07:51:36.641200 | Earlean |
elmlang | general | <@Leopoldo> did this solve your problem? | 2019-02-17T09:32:54.641900 | Moshe |
elmlang | general | yes, i have a full working page <https://gist.github.com/afidegnum/a26cae4270961855e197188c2430f293> | 2019-02-17T09:33:18.642100 | Leopoldo |
elmlang | general | i m now trying to open a form and interact with individual items of the list | 2019-02-17T09:33:38.642300 | Leopoldo |
elmlang | general | have fun :slightly_smiling_face: | 2019-02-17T09:34:01.642500 | Moshe |
elmlang | general | thanks a lot for your help | 2019-02-17T09:34:16.642700 | Leopoldo |
elmlang | general | I hope you had some rest in between :smile: and no problem :slightly_smiling_face: | 2019-02-17T09:34:33.642900 | Moshe |
elmlang | general | yes, but i want to finish this at once, rest a bit, move to the next chapter :slightly_smiling_face: | 2019-02-17T09:35:07.643100 | Leopoldo |
elmlang | general | I have CORS enabled, i have been able to fetch the items, but when Posting a new form, i have a `Cannot GET /page` error. there is now GET `page` request on the server, | 2019-02-17T10:03:24.645800 | Leopoldo |
elmlang | general | what can be the cause? | 2019-02-17T10:03:32.646100 | Leopoldo |
elmlang | general | You need to be more explicit, do you explicitly send a POST request from Elm code? How do you send the post request from Elm code? | 2019-02-17T13:22:29.646400 | Dorethea |
elmlang | general | furthermore seems like needs to be asked on <#C192T0Q1E|beginners> | 2019-02-17T13:23:28.646600 | Dorethea |
elmlang | general | i think the POST is sent from line 175 | 2019-02-17T13:23:42.646800 | Leopoldo |
elmlang | general | in line 138 you are concatanating `links` and `"page"` and `pageid` you do not use any slash, maybe you are passing pageid blank string, that's why it is trying to GET `/page` ? | 2019-02-17T13:28:07.647000 | Dorethea |
elmlang | general | You should use `/` btw if i'm not wrong? | 2019-02-17T13:28:35.647200 | Dorethea |
elmlang | general | well, there have not been a POST request call from the server, | 2019-02-17T13:29:01.647400 | Leopoldo |
elmlang | general | only GET all along | 2019-02-17T13:29:07.647600 | Leopoldo |
elmlang | general | <@Dorethea> you are right `/page` made it work | 2019-02-17T13:34:46.647800 | Leopoldo |
elmlang | general | it even returned `OPTIONS` i don't know why | 2019-02-17T13:35:08.648000 | Leopoldo |
elmlang | general | but i m still facing the `Cannot GET /pages` error | 2019-02-17T13:37:49.648300 | Leopoldo |
elmlang | general | When you are initializing your app you are issueing fetchPages command, which sends a get request to `/pages` so Elm works | 2019-02-17T14:21:41.648500 | Dorethea |
elmlang | general | Why your server doesn't work the way you want it to IDK | 2019-02-17T14:21:57.648700 | Dorethea |
elmlang | general | it's now working, except the `Cannot GET /page` error i don't understand and after submitting the form the url redirects to localhot:9000/page? | 2019-02-17T14:23:45.649000 | Leopoldo |
elmlang | general | Are there any plans to make this part of the debugger resizable? Am I missing something? | 2019-02-17T17:01:29.649200 | Valorie |
elmlang | general | You can hover the lines and it'll tooltip it for you | 2019-02-17T17:11:16.649500 | Martin |
elmlang | general | not great, but works | 2019-02-17T17:11:21.649700 | Martin |
elmlang | general | that’s better | 2019-02-17T17:15:21.650000 | Valorie |
elmlang | general | but still displays an ellipsis if the message is too long | 2019-02-17T17:15:32.650200 | Valorie |
elmlang | general | I usually end up removing the `width` property from the `sidebar`/whatever the css class for it is so it goes width 100%. | 2019-02-17T17:24:04.650500 | Lizabeth |
elmlang | general | I did a workaround ellipsis in 0.18 by changing some Elm codes. The file path would be different, but there shouldn‘t be a significant change to the code.

elmlang | general | So, thanks to you fine gentlepeople we got from 1min 5s compilation time to about 25s :slightly_smiling_face: thanks. | 2019-02-18T04:52:04.663900 | Antonette |
elmlang | general | Hello, I have a listing with multiple cards. I was thinking about making cards modular by moving a local state in their own model. no problem for init or views, but how would I target the right subModel in an update function? Is this a good pattern? | 2019-02-18T12:52:07.667200 | Elza |
elmlang | general | I have thought about adding the subModel to the msg, but I do not see a way of updating the parent Model | 2019-02-18T12:53:30.668300 | Elza |
elmlang | general | <@Elza> Introducing "child" triplets (i.e. modules with their own init/update/view and Model/Msg) is generally not considered as a good pattern but it depends on your app and its structure. For example, it is very practical having single pages in an SPA as stand-alone triplets. | 2019-02-18T12:58:11.670400 | Lynne |
elmlang | general | I doubt it is a good idea for cards though. | 2019-02-18T12:59:03.671100 | Lynne |
elmlang | general | yes that is what I am using in single pages | 2019-02-18T12:59:07.671300 | Elza |
elmlang | general | but I hear you for smaller components | 2019-02-18T12:59:16.671500 | Elza |
elmlang | general | I am considering alternatives | 2019-02-18T12:59:23.671700 | Elza |
elmlang | general | ok | 2019-02-18T12:59:44.671900 | Elza |
elmlang | general | will be using a `Set` instead to mark instances I need instead of submodules/child triplets | 2019-02-18T13:00:12.672100 | Elza |
elmlang | general | `Set` can only contain comparables | 2019-02-18T13:00:35.672400 | Lynne |
elmlang | general | You are probably after the `List` | 2019-02-18T13:00:46.672600 | Lynne |
elmlang | general | sorry i meant a `List` containing models, with a `Set` to tag some of them by `id` | 2019-02-18T13:36:26.672800 | Elza |
elmlang | general | hello, my brain just emptied... i am having hard time incorporating `viewOnepage` <https://ellie-app.com/4LPyRxJvFcBa1> | 2019-02-18T14:01:13.673800 | Leopoldo |
elmlang | general | i wanted to fetch and load content of a single page ID | 2019-02-18T14:01:42.674200 | Leopoldo |
elmlang | general | Has anyone seen any info on how to create an interface like this using native Elm (i.e., not using ports)? I don't have a specific application, it just looks like it would be cool to make. | 2019-02-18T18:46:43.675000 | Marcus |
elmlang | general | BTW, that's a shot from Twilio Studio - a tool for visually creating messaging flows. | 2019-02-18T18:47:13.675700 | Marcus |
elmlang | general | I'd be interested in that, I'm looking to build a graph (nodes and edges) editor in Elm | 2019-02-18T19:10:21.676200 | Vashti |
elmlang | general | I'm not sure how to describe such an interface | 2019-02-18T19:10:50.676700 | Vashti |
elmlang | general | "canvas interfaces" maybe (as in the user can somewhat arbitrarily place and move objects on a canvas) | 2019-02-18T19:11:14.677300 | Vashti |
elmlang | general | but the word canvas already has a specific meaning when it comes to webdev | 2019-02-18T19:11:27.677700 | Vashti |
elmlang | general | I'm not sure either. FWIW, the implementation of that interface is all SVG. I was worried it might be HTML Canvas, but that's not the case, fortunately. | 2019-02-18T20:11:41.679700 | Marcus |
elmlang | general | I'd probably describe it as a workflow editor. | 2019-02-18T20:15:01.680200 | Marcus |
elmlang | general | This gets close, but looks like a piece of a larger platform, not a stand-alone component: <https://www.totaljs.com/flow/> | 2019-02-18T20:19:06.680800 | Marcus |
elmlang | general | <@Marcus> I guess you could build the svg based on input messages using elm/svg somehow and then render that | 2019-02-18T20:36:56.681400 | Vashti |
elmlang | general | the problem is you'd somehow have to keep track exactly of where every element in the svg is on the page? | 2019-02-18T20:37:24.682000 | Vashti |
elmlang | general | so that you can correctly interpret a click | 2019-02-18T20:37:40.682300 | Vashti |
elmlang | general | which sounds scarily like it could get very platform dependent quickly | 2019-02-18T20:37:55.682700 | Vashti |
elmlang | general | <@Vashti> I think you are right about the implementation. You'd need to store the x,y location of each node in the workflow. The edges between them could be calculated on the fly. I'd probably set the center of the design surface to be 0,0 and allow nodes to be placed anywhere in relation to that. The messages would be something like `AddNode`, `DeleteNode`, `NodeDragging`, and `NodeDropped`. I'm shooting from the hip a bit there, but that's where I'd start. | 2019-02-18T20:53:34.686800 | Marcus |
elmlang | general | yup, sounds about right | 2019-02-18T20:55:21.687000 | Vashti |
elmlang | general | my only worry is converting window level coordinates that the browser sends you on a click to surface coordinates | 2019-02-18T20:55:49.687600 | Vashti |
elmlang | general | I'd need to be certain the SVG was being drawn _exactly_ where I thought | 2019-02-18T20:56:00.688100 | Vashti |
elmlang | general | and I kind of have a hunch that's a dangerous assumption to make | 2019-02-18T20:56:20.688500 | Vashti |
elmlang | general | I don't have my head around that one either. The examples I've seen of drag-and-drop functionality with Elm haven't been great. | 2019-02-18T21:16:41.689500 | Marcus |
elmlang | general | <@Marcus> got any examples you could share off the top of your head? | 2019-02-18T21:21:30.690000 | Vashti |
elmlang | general | I may have to move away from elm, or just use ports for that component of the UI | 2019-02-18T21:21:44.690500 | Vashti |
elmlang | general | One sec. I'll see if I can find it. | 2019-02-18T21:32:08.690800 | Marcus |
elmlang | general | <https://github.com/wintvelt/elm-sortable-list> | 2019-02-18T21:33:17.691000 | Marcus |
elmlang | general | There's one. There's another that I'm thinking of though. I feel like it came with the old Elm mouse event library. | 2019-02-18T21:33:42.691600 | Marcus |
elmlang | general | This just came up in my search: <https://www.youtube.com/watch?v=YbzNit_D98Y> | 2019-02-18T21:34:41.691900 | Marcus |
elmlang | general | That looks interesting. | 2019-02-18T21:34:45.692100 | Marcus |
elmlang | general | thanks very much | 2019-02-18T21:34:59.692400 | Vashti |
elmlang | general | I feel like `elm/browser` got some updates in 0.19 that might help. Unconfirmed though. | 2019-02-18T21:35:37.693200 | Marcus |
elmlang | general | oh that talk is _very_ interesting | 2019-02-18T21:37:17.693700 | Vashti |
elmlang | general | I don't know if it's something supported natively by the svg package but they can set mouse event attributes directly on their svg nodes | 2019-02-18T21:37:55.694400 | Vashti |
elmlang | general | Interesting. I didn't know that. | 2019-02-18T21:38:26.694600 | Marcus |
elmlang | general | I need to improve my SVG knowledge. | 2019-02-18T21:38:37.694900 | Marcus |
elmlang | general | <https://package.elm-lang.org/packages/elm/svg/latest/Svg-Events#onClick> | 2019-02-18T21:39:36.695100 | Vashti |
elmlang | general | well, that means it's considerably easier than I expected | 2019-02-18T21:39:48.695400 | Vashti |
elmlang | general | Yeah, the `onMouseDown` and `onMouseUp` seem like they would do the trick. | 2019-02-18T21:40:23.695900 | Marcus |
elmlang | general | that's very nice | 2019-02-18T21:40:42.696100 | Vashti |
