elmlang | general | thanks a lot. I will give a try | 2019-01-28T10:48:58.133500 | Phoebe |
elmlang | general | omg it worked! thanks a lot | 2019-01-28T10:53:37.133700 | Phoebe |
elmlang | general | hello everyone I’m having some issues javascript stuff I think | 2019-01-28T11:12:03.135100 | Karrie |
elmlang | general | I include `<.script src="./assets/scripts/modules/reservations.js"></script>`
and straight below I initialise my Elm app:
`Elm.Main.init({node: ….})` | 2019-01-28T11:13:00.136100 | Karrie |
elmlang | general | the issue is I get the following error: `ReferenceError: Elm is not defined` | 2019-01-28T11:13:28.136600 | Karrie |
elmlang | general | is this something you every came across? | 2019-01-28T11:15:07.137000 | Karrie |
elmlang | general | <@Karrie> Do you mean that you've put the `Elm.Main.init(...)` in your `reservations.js` file or in your html file? | 2019-01-28T11:15:54.137900 | Antonette |
elmlang | general | Elm.Main.init is my html file | 2019-01-28T11:16:10.138200 | Karrie |
elmlang | general | Is it possible that you show your `reservations.js` file? (like on a pastebin or something) | 2019-01-28T11:17:17.139500 | Antonette |
elmlang | general | <@Antonette> sure: here you go: <https://pastebin.com/JiZULbDJ> | 2019-01-28T11:18:57.139800 | Karrie |
elmlang | general | Thanks :slightly_smiling_face: | 2019-01-28T11:19:06.140200 | Antonette |
elmlang | general | if I try to import the file into my main `theme.js` file I get the following error:
`TypeError: scope is undefined` | 2019-01-28T11:23:23.140900 | Karrie |
elmlang | general | What are you using to compile your JavaScript? | 2019-01-28T11:27:44.141400 | Antonette |
elmlang | general | the “normal” javascript or the Elm app? | 2019-01-28T11:28:51.141800 | Karrie |
elmlang | general | I’m trying to integrate my Elm app into a shopify template | 2019-01-28T11:29:37.142400 | Karrie |
elmlang | general | this is done via Slate (<https://github.com/Shopify/slate/>) which uses babel | 2019-01-28T11:30:34.142900 | Karrie |
elmlang | general | Ok ; I'm sorry but I'm about to have to leave my keyboard. Anyone else can help debug? | 2019-01-28T11:33:13.144100 | Antonette |
elmlang | general | <@Antonette> no worries! the elm file is created with `elm make src/Main.elm` and everything else is done using slate | 2019-01-28T11:34:28.145400 | Karrie |
elmlang | general | any help from anyone would be great! | 2019-01-28T11:34:38.145700 | Karrie |
elmlang | general | Good luck :slightly_smiling_face: | 2019-01-28T11:35:02.146200 | Antonette |
elmlang | general | Where is your script tag and where are is your `Elm.init` script <@Karrie>? | 2019-01-28T12:23:15.147800 | Ashton |
elmlang | general | I havent had a problem like that in a while, but I remember when I did I usually found the solution by fiddling with where the script tags are. | 2019-01-28T12:23:44.148500 | Ashton |
elmlang | general | Have you tried like
```
<head>
<script src="./reservations.js"/>
</head>
<body>
<script>
Elm.init()
</script>
</body>
``` | 2019-01-28T12:24:27.149400 | Ashton |
elmlang | general | ? | 2019-01-28T12:24:30.149600 | Ashton |
elmlang | general | With the Elm initialization in the body. | 2019-01-28T12:25:05.150100 | Ashton |
elmlang | general | it could it be related to <https://github.com/elm/core/issues/993> if the subscription is conditional | 2019-01-28T12:41:26.150300 | Alicia |
elmlang | general | Can anyone explain to me what the exact difference between `Parser.keyword`, `Parser.symbol` and `Parser.token` is? | 2019-01-28T13:25:08.151400 | Freda |
elmlang | general | I think from looking at the code in `Parser.Advanced` symbol and keyword are the same. | 2019-01-28T13:25:37.152000 | Freda |
elmlang | general | ```symbol : Token x -> Parser c x ()
symbol =
token``` | 2019-01-28T13:25:50.152300 | Freda |
elmlang | general | But what is the difference to `keyword` then? | 2019-01-28T13:26:01.152600 | Freda |
elmlang | general | I think `keyword` peeks ahead a littlebit to ensure there’s whitespace afterwards. | 2019-01-28T13:27:07.153100 | Cornell |
elmlang | general | Or rather “not a letter, number, or underscore” | 2019-01-28T13:28:07.153400 | Cornell |
elmlang | general | Ah ok, so it makes sure that it is what you were looking, and not more than that. Thanks :slightly_smiling_face: | 2019-01-28T13:31:04.154600 | Freda |
elmlang | general | Any idea why there is a `token` and a `symbol` if they seem to be the same thing? | 2019-01-28T13:31:27.155200 | Freda |
elmlang | general | I think it’s the same except it will give a different `Problem`: <https://package.elm-lang.org/packages/elm/parser/latest/Parser#Problem> | 2019-01-28T13:33:56.155700 | Cornell |
elmlang | general | I think `token` corresponds to `Expecting String`, while `symbol` corresponds to `ExpectingToken` | 2019-01-28T13:35:24.156900 | Cornell |
elmlang | general | Which could be useful for error reporting. | 2019-01-28T13:35:33.157200 | Cornell |
elmlang | general | Ah ok, so apart from errors they are the same. Thanks Matt | 2019-01-28T13:38:41.157700 | Freda |
elmlang | general | No problemo! | 2019-01-28T13:39:03.157900 | Cornell |
elmlang | general | after a long debugging session I found out that the problem wasn’t with my Elm component but with the stupid Shopify! | 2019-01-28T13:47:36.158000 | Karrie |
elmlang | general | Just got it fixed but thank you all! <@Ashton> <@Antonette> | 2019-01-28T13:47:58.158200 | Karrie |
elmlang | general | anyone have any good idea on how to refresh short term access tokens and have it propogate down to children? | 2019-01-28T14:20:53.159200 | Euna |
elmlang | general | also: is this explanation still relevant in .19? | 2019-01-28T14:21:32.159800 | Euna |
elmlang | general | <https://www.reddit.com/r/elm/comments/48pqsh/updated_nested_child_components/d0n3n0v/> | 2019-01-28T14:21:32.159900 | Euna |
elmlang | general | I feel like the most Elm-ish thing to do would be to keep the tokens at the top level of model and have the children just grab them from there, no? | 2019-01-28T14:45:49.160700 | Dede |
elmlang | general | There is no such thing as "component state" in Elm. All state lives on a single top-level model. | 2019-01-28T14:50:57.161300 | Carman |
elmlang | general | you may be passing different sub-chunks of that model into various view functions | 2019-01-28T14:51:45.162000 | Carman |
elmlang | general | which may feel like "component state" from other frameworks | 2019-01-28T14:51:58.162400 | Carman |
elmlang | general | but it's important to remember that at the end of the day it's a single big state | 2019-01-28T14:52:34.162900 | Carman |
elmlang | general | You generally want to keep that state DRY (Elm folks might say "make impossible states impossible") | 2019-01-28T14:52:59.163300 | Carman |
elmlang | general | So you'd want to avoid duplicating tokens all over your model. Ideally the token lives in a single place | 2019-01-28T14:53:33.163900 | Carman |
elmlang | general | guys, I mean that the whole point. What I'm saying is there a way to take the top level Msg (Result Err a) and update the child components without have to pattern match every sub model | 2019-01-28T15:03:33.164800 | Euna |
elmlang | general | I would like to avoid pattern matching two different Msg to every submodel | 2019-01-28T15:04:20.165900 | Euna |
elmlang | general | If you do have pages with their own Model and Msg types, this example app I have may be helpful: <https://github.com/ohanhi/elm-shared-state> | 2019-01-28T15:04:46.166600 | Bert |
elmlang | general | I've been using feldman's SPA app as reference, but as far as I can tell he doesn't update tokens during the session | 2019-01-28T15:04:52.166800 | Euna |
elmlang | general | <@Euna> Store the token in your top-level `Model`, pass the token to the child `update` functions when you call them. Then you only have to update a single field when it changes. | 2019-01-28T15:08:40.168000 | Earnest |
elmlang | general | <@Euna> When you say "component" -- do you mean pages in an SPA, or something more like datepickers? | 2019-01-28T15:15:05.168800 | Dede |
elmlang | general | Or something else? | 2019-01-28T15:15:18.169100 | Dede |
elmlang | general | <@Dede> i mean children/page sure | 2019-01-28T15:16:21.169500 | Euna |
elmlang | general | None | 2019-01-28T15:17:29.169800 | Euna |
elmlang | general | the reason this is coming up is that I have refreshing the tokens on a timed task, so its a top level subscription | 2019-01-28T15:18:26.170800 | Euna |
elmlang | general | In the rtfeldman SPA, I think you'd have the top level update function call `toSession` (is that right? This is from memory) to get the session, update the token in the session, and then re-build the current page (probably another big `case` statement) passing in the new session. | 2019-01-28T15:20:23.172400 | Dede |
elmlang | general | Hi, there there a way to send a Cmd that doesn't do anything other than trigger a new update? I know I can just call my `update` function directly but what I want is for the message to appear in the debugger history | 2019-01-28T15:21:46.173800 | Jae |
elmlang | general | <@Jae> you can make a cmd that takes in nothing, the NoOp causes a refresh iirc | 2019-01-28T15:23:05.174700 | Euna |
elmlang | general | * the NoOp from the elm-tutorial | 2019-01-28T15:23:19.175000 | Euna |
elmlang | general | ```
send : msg -> Cmd msg
send msg =
Task.succeed msg
|> Task.perform identity
```
This is not good practice though. | 2019-01-28T15:24:31.175500 | Velia |
elmlang | general | <@Jae> `Task.succeed () |> Task.perform (always <| myActualMsg)` | 2019-01-28T15:24:39.175800 | Earnest |
elmlang | general | hot damn that's good | 2019-01-28T15:28:26.176100 | Euna |
elmlang | general | Yeah, making it a `NoOp` won't do anything... I think they want to call the code from a specific update branch | 2019-01-28T15:29:49.177000 | Earnest |
elmlang | general | oooo | 2019-01-28T15:30:07.177500 | Euna |
elmlang | general | Well a proper NoOp at least, `NoOp -> (model, Cmd.none)` | 2019-01-28T15:30:23.177900 | Earnest |
elmlang | general | That said, I usually refactor the branch into a separate function and call it from both branches instead of recursive updates or sending Cmds. | 2019-01-28T15:30:59.178500 | Earnest |
elmlang | general | Yup, that works. Thanks! (Don't worry, I plan to use it for debugging only) | 2019-01-28T15:34:30.179900 | Jae |
elmlang | general | That works, thanks! | 2019-01-28T15:34:49.180100 | Jae |
elmlang | general | <@Dede> he batches session changes as a subscription to each page in order to not redraw it | 2019-01-28T15:42:02.180900 | Euna |
elmlang | general | I think I might do that too | 2019-01-28T15:42:08.181100 | Euna |
elmlang | general | I don't think I'm fluent enough to come up with a more elegant solution | 2019-01-28T15:42:27.181600 | Euna |
elmlang | general | ¯\_(ツ)_/¯ | 2019-01-28T15:42:31.181700 | Euna |
elmlang | general | I'm trying to install "elm/bytes", but I get the error: "WARNING: I normally check <https://package.elm-lang.org> for new packages
here, but my request failed. Are you offline? I will try to continue anyway." | 2019-01-28T18:15:15.182800 | Raylene |
elmlang | general | <@Raylene> are you behind a proxy server? | 2019-01-28T18:21:38.183400 | Earlean |
elmlang | general | I have a quick scaling/decomposition question. I have an app that does search. It allows a user to build a query and then it shows the results. The file is huge (several thousand lines), so I'm breaking it up into some modules. Specifically, I'm going to move the search results type into its own module, along with the decoders, http method, etc. | 2019-01-28T22:10:20.186300 | Marcus |
elmlang | general | My question is this. Getting the results depends upon the model in my Main file. I don't want to set up a circular dependency. Can I just be careful with my `exposings` and include `Main` in `SearchResults`, or do I need to move my model into its own file also? | 2019-01-28T22:11:31.187700 | Marcus |
elmlang | general | <@Marcus> if you've got code that depends on the Main model then it should probably be in the Main module. | 2019-01-28T22:17:33.188400 | Earlean |
elmlang | general | Well, everything is in the Main module now. | 2019-01-28T22:18:02.189300 | Marcus |
elmlang | general | But, if your model is a record type alias you could use the 'extensible record' syntax to depend only on the fields you need to | 2019-01-28T22:18:38.189900 | Earlean |
elmlang | general | Good point. I underuse that feature. | 2019-01-28T22:18:58.190500 | Marcus |
elmlang | general | <@Marcus> another way to see it is to decouple your model from your `Main` module, so it's accessible by both the `Main` module and the `SearchResults` without circular dependencies. | 2019-01-29T03:51:03.191600 | Antonette |
elmlang | general | Hi! Do you know of any REPL in the browser solution? | 2019-01-29T04:12:33.196400 | Dorsey |
elmlang | general | If I understand correctly Ellie compiles Elm code on the client side. Is there something like that for REPL? The only thing I could find is this <http://elmrepl.cuberoot.in/>, but it seems to connect to some server to evaluate the code. Also I don't know what the terms of use are, is there a source code available, etc. | 2019-01-29T04:12:37.196500 | Dorsey |
elmlang | general | I just use <https://ellie-app.com>, even though it's not exactly a REPL | 2019-01-29T04:14:02.196700 | Nana |
elmlang | general | Me too, but I need something where I can evaluate simple expressions for teaching. | 2019-01-29T04:14:56.196900 | Dorsey |
elmlang | general | We will be using Ellie to build the app, but we also need REPL. | 2019-01-29T04:15:26.197100 | Dorsey |
elmlang | general | `main = myExpression |> Debug.toString |> text` | 2019-01-29T04:15:33.197300 | Nana |
elmlang | general | :thinking_face: | 2019-01-29T04:15:48.197500 | Dorsey |
elmlang | general | That's something worth considering. | 2019-01-29T04:16:01.197700 | Dorsey |
elmlang | general | You don't get type inference though. | 2019-01-29T04:16:17.197900 | Dorsey |
elmlang | general | that's true, hey that would be cool to have as a Debug function! | 2019-01-29T04:17:11.198100 | Nana |
elmlang | general | Yes it would :smile: | 2019-01-29T04:17:26.198300 | Dorsey |
elmlang | general | like `Debug.type` | 2019-01-29T04:17:29.198500 | Nana |
elmlang | general | I think it may be difficult. The types don't make it to the runtime, AFAIK. | 2019-01-29T04:17:59.198700 | Dorsey |
