elmlang | general | Okay, so we're at least in theory avoiding double encoding (though I don't think that's true because somewhere that string is still probably going to get a `JSON.stringify` to go through the port, though it may be trivial performance wise even for large data). | 2019-02-21T14:42:08.075700 | Rosaria |
elmlang | general | Anyway, all besides the point. | 2019-02-21T14:42:51.076300 | Rosaria |
elmlang | general | There’s no stringify that happens when going through ports. | 2019-02-21T14:43:50.078200 | Danika |
elmlang | general | <@Agustin> The most important thing however that you haven't touched on is is there code generation for these GraphQL things? Do I have to write clients for it by hand with support libraries? | 2019-02-21T14:43:50.078300 | Rosaria |
elmlang | general | No, the most popular library generates elm for your graphql | 2019-02-21T14:44:31.079100 | Agustin |
elmlang | general | You still have to couple that to your code | 2019-02-21T14:44:39.079500 | Agustin |
elmlang | general | Okay, that's a huge relief. | 2019-02-21T14:44:42.079700 | Rosaria |
elmlang | general | But the “decoding” is handled | 2019-02-21T14:44:46.080000 | Agustin |
elmlang | general | <@Danika> Ah I see. Before the json passing in ports occurred, elm had hardcode support for its basic types through ports. | 2019-02-21T14:46:38.081300 | Rosaria |
elmlang | general | That's excellent news. | 2019-02-21T14:46:40.081500 | Rosaria |
elmlang | general | Hey there, I am searching for the complete schema of "--report=json" compiler flag... is that JSON schema just the same for every type of error/warning/message ? | 2019-02-21T15:32:23.084100 | Cherish |
elmlang | general | currently I am reengineering the schema from concrete error messages, but that seems somewhat inefficient and tedious.. | 2019-02-21T15:33:35.084900 | Cherish |
elmlang | general | This didn't help?

elmlang | general | TLDR; contextually rendered UI loses bindings in IE 11
Hi there, I have the singular misfortune of having to support IE11 for our app, and while it works reasonably well, there is an issue where the app seems to lose its binding for overlays, i.e DOM that is rendered contextually based on a user interaction.
I can verify that if I render the overlay on page load, I can interact with it ( (I can verify the responsiveness by watching the elm debugger), but when I close it and reopen it the overlay eventually loses it bindings, and becomes non-responsive. By eventually, I mean that I can reopen and close the overlay 0 or more times, but typically no more than 5, so this suggests that perhaps the issue is in IE’s event loop handling of the runtime, which, well, is not a cause for much optimism that this issue is easily fixable.
Has anyone else experienced this issue with IE11 and if so, how did you mitigate it.
thanks all! | 2019-02-21T16:16:44.094000 | Kaitlin |
elmlang | general | By loses bindings, do you mean there are no event handlers registered, or do you see errors in the console when interacting? | 2019-02-21T16:20:33.095600 | Huong |
elmlang | general | there are no console errors or elm debugger updates | 2019-02-21T16:21:11.096200 | Kaitlin |
elmlang | general | That's pretty weird! I've had issues where events would result in errors due to some weird edge case with html.map that only pops up in IE 11, but haven't run into a complete lack of interaction! | 2019-02-21T16:23:09.098400 | Huong |
elmlang | general | yeah, it’s very weird! | 2019-02-21T16:26:11.098800 | Kaitlin |
elmlang | general | <@Huong> you are a genius. your comment about Html.map inspired me to look at how I was constructing the DOM where the overlay was rendered, and indeed I was doing something rather weird with Html.map
basically I was doing this:
```div [] <|
List.map (Html.map myFooMsg)
[ viewNode1
, viewOverlay
, viewNode2
, viewNode3
]```
when I should have been doing this :
```Html.map myFooMsg
<| div []
[ viewNode1
, viewOverlay
, viewNode2
, viewNode3
]``` | 2019-02-21T16:49:03.102400 | Kaitlin |
elmlang | general | using the latter structure makes my overlay 100% functional. | 2019-02-21T16:50:27.103400 | Kaitlin |
elmlang | general | I’m not sure why that would be the case, but i know the original way I was doing it is obviously not idiomatic | 2019-02-21T16:51:29.104400 | Kaitlin |
elmlang | general | Yeah, that's actually the bug I was referring to. Having an indirection between the node and the mapped contents seems to make this problematic, for whatever reason. Anyway, glad that helped! | 2019-02-21T17:00:10.106700 | Huong |
elmlang | general | <@Velia> great!
I just can't produce this for testing:
`ModuleProblems (List BadModule)`
I have 2 Modules, each of which have 1 error, but I get only 1 "BadModule" from the json-report
this is what never produced something more than one element:
<https://github.com/elm/project-metadata-utils/blob/1d43c1a660c4f7dca9f14e64a050ac3971141221/src/Elm/Error.elm#L69> | 2019-02-21T17:09:42.106800 | Cherish |
elmlang | general | ah.. I think I just got it:
there will be >1 module-errors only, if I compile multiple _independent_ modules
if I use moduleB in moduleA (that is, moduleA imports moduleB !), only the first error is reported, and which depends on whichever module will be checked by the compiler first | 2019-02-21T17:17:34.107300 | Cherish |
elmlang | general | Really great talks from Oslo Elm Day. Almost finished watching all of them. | 2019-02-21T17:52:53.108300 | Wendell |
elmlang | general | What is the best way to call an Elm function from Js. I have a parser implemented in Elm and would really love to be able to call the function synchronously from Js so I don’t have to reimplement the same thing in Js. | 2019-02-21T18:14:36.110900 | Kathlyn |
elmlang | general | I am perfectly fine with encoding and decoding stuff as needed. | 2019-02-21T18:17:52.111400 | Kathlyn |
elmlang | general | Send the text to be parsed in through a port, encode a JSON object of the AST or whatever and send it back out. | 2019-02-21T18:19:16.111600 | Cammy |
elmlang | general | You have mostly 2 options for doing it synchronously, something like this: <https://medium.com/@jjant/making-elm-unsafe-cc6435495af2> or using a trick with decoding/encoding a proxy | 2019-02-21T18:20:09.111800 | Kris |
elmlang | general | These are not the officially recommended options etc etc | 2019-02-21T18:20:34.112000 | Kris |
elmlang | general | <@Cammy> Yeah, was hoping for an sync way of doing it as the thing I have to integrate with requires it. Thanks all the same | 2019-02-21T18:22:21.112200 | Kathlyn |
elmlang | general | Is the current state of running elm with the debugger enabled that you can’t use Lists in your Msg’s? If been reading on the bug reports but they mainly talk about the usage of Arrays and opt to convert them in to lists for your messages, but a List also reports ```elm: Map.!: given key is not an element in the map``` | 2019-02-21T19:01:40.114100 | Dexter |
elmlang | general | Unfortunately yes. There is a fork of the compiler that fixes this issue:
<https://github.com/tomstejskal/compiler>
The official fix will be part of `0.19.1` but there are other issues being fixed that will delay that release some more time. | 2019-02-22T01:10:08.115900 | Maida |
elmlang | general | How to iterate over struct | 2019-02-22T02:41:44.116400 | Chi |
elmlang | general | you mean over the fields of a struct? If so, it is not possible as that would mean iterate over values of different types. | 2019-02-22T02:45:01.116500 | Elza |
elmlang | general | <@Chi> what are you wanting to do? | 2019-02-22T02:45:44.116700 | Iona |
elmlang | general | struct have different type lets say struct {data:List String, id: int} | 2019-02-22T02:47:20.116900 | Chi |
elmlang | general | yes? | 2019-02-22T02:48:04.117200 | Iona |
elmlang | general | i want to iterate over it List of struct | 2019-02-22T02:48:47.117500 | Chi |
elmlang | general | What do you whant to do in the iteration? Applying a function to the records? A filter? something else? | 2019-02-22T02:51:53.117800 | Allyn |
elmlang | general | Hello. I struggle to apply a list of filters to a list of values. I made a simplified example in ellie: <https://ellie-app.com/4NpDSmYhdvMa1> | 2019-02-22T02:53:12.119100 | Allyn |
elmlang | general | want to apply funtion | 2019-02-22T02:54:21.119200 | Chi |
elmlang | general | So use List.map: <https://package.elm-lang.org/packages/elm/core/latest/List#map> | 2019-02-22T02:55:33.119400 | Allyn |
elmlang | general | I'm just going to give you the answer. But feel free to ask any questions so we can help you understand it
```
applyFilters : List Int -> List (Int -> Bool) -> List Int
applyFilters values filters =
List.foldl (\filter remainingValues -> List.filter filter remainingValues) values filters
``` | 2019-02-22T02:57:59.119600 | Sharon |
elmlang | general | It doesn’t seem to produce the expected result in my example | 2019-02-22T03:01:16.119900 | Allyn |
elmlang | general | <https://ellie-app.com/4NpPhpwLXZfa1> | 2019-02-22T03:01:17.120100 | Allyn |
elmlang | general | oh I thought all filters had to be applied,sorry :slightly_smiling_face: | 2019-02-22T03:02:37.120300 | Sharon |
elmlang | general | so if any filter returns true, the element can stay | 2019-02-22T03:03:04.120500 | Sharon |
elmlang | general | No, it’s my example which is bad, your solution is OK | 2019-02-22T03:03:32.120700 | Allyn |
elmlang | general | sorry | 2019-02-22T03:03:41.121000 | Allyn |
elmlang | general | And thank you for your help | 2019-02-22T03:03:55.121200 | Allyn |
elmlang | general | Just in case you are interested in OR filters, there is a function in `list-extra` which may be helpful: `List.Extra.lift2` | 2019-02-22T03:05:36.121500 | Lynne |
elmlang | general | You could patch out the check about which repos are allowed to produce kernel code. | 2019-02-22T03:38:47.122200 | Niesha |
elmlang | general | But you'd be on your own writing kernel code. | 2019-02-22T03:39:04.122400 | Niesha |
elmlang | general | Hey peeps - Is there a way to generate inline styles with elm-css? | 2019-02-22T03:56:46.123000 | Teri |
elmlang | general | Can't find it in the docs nor issues? | 2019-02-22T03:56:56.123200 | Teri |
elmlang | general | It is actually interleaved with installed modules. If you put the consumed modules in your source directory rather than the elm packages directory the error goes away. | 2019-02-22T03:58:06.123300 | Teri |
elmlang | general | Is <http://package.elm-lang.org|package.elm-lang.org> broken for anyone else? <https://package.elm-lang.org/packages/jinjor/elm-debounce/latest/Debounce> I can't click any links, I just get

elmlang | general | That seems to happen whenever I move the mouse | 2019-02-22T06:15:11.131000 | Shelia |
elmlang | general | Ok, looks like it's my Stay Focused Chrome extension | 2019-02-22T06:17:29.132600 | Shelia |
elmlang | general | <@Shelia> yep, that error is the result of something outside Elm messing with Elm's part of the DOM | 2019-02-22T06:17:48.133000 | Earlean |
elmlang | general | perhaps Stay Focused should be mentioned as an example here? <https://discourse.elm-lang.org/t/fullscreen-elm-app-in-0-19-childnode-issue-reopened/3174/9> (if <http://package.elm-lang.org|package.elm-lang.org> is using `Browser.application`) | 2019-02-22T06:20:53.134000 | Lewis |
elmlang | general | How many frontend devs does NoRedInk have? Working on a presentation about Elm :slightly_smiling_face: | 2019-02-22T07:39:06.137100 | Nana |
elmlang | general | Hello all! We're under threat from a decision-maker for our use of Elm so we're writing a big post on *"Why Choose Elm in 2019"*. We would _very much appreciate your help_ with a :+1: and sharing any success stories and challenges you've had on this post with our outline so we can make it comprehensive :hearts: <https://github.com/dwyl/learn-elm/issues/129> | 2019-02-22T09:03:11.140100 | Charley |
elmlang | general | <@Nana> Looks like their website doesn't differentiate between front end and back end, just roughly 25 engineers: <https://www.noredink.com/about/team> :slightly_smiling_face: | 2019-02-22T09:04:10.140300 | Charley |
elmlang | general | Oh, that's kind of what I'm doing too! Although for me it's actually more our Java developers. My boss was more "reliability sounds good" | 2019-02-22T09:15:20.141800 | Nana |
elmlang | general | Ah thanks, I see :thinking_face: | 2019-02-22T09:20:04.142100 | Nana |
elmlang | general | <@Nana> We're dedicating our time to it next week without fail so maybe we could share ideas as we go through? If you could put the word out maybe we could collect some wider experience for everyone! | 2019-02-22T09:20:37.142300 | Charley |
elmlang | general | Hi! Does anyone know the algorithm used for the Elm type checker? | 2019-02-22T09:45:41.143200 | Randi |
elmlang | general | I think it's based on this: <https://en.wikipedia.org/wiki/Hindley%E2%80%93Milner_type_system> | 2019-02-22T09:47:30.143300 | Nana |

elmlang | general | We don't differentiate internally either | 2019-02-22T10:46:37.144500 | Sherilyn |

elmlang | general | Does anyone know if its possible to change the location of the elm-stuff directory? (Not to be confused with the .elm directory.) I'm trying to work around some unfortunate read-only drive problems and it would be great if I could move it to another location. | 2019-02-22T11:44:14.147000 | Lavon |
elmlang | general | `elm-stuff` is always created in the same directory as your `elm.json`. However, you might be able to move your `elm.json` and update its `source-directories` entry accordingly? | 2019-02-22T11:45:47.148000 | Huong |
elmlang | general | while we do use Elm at Microsoft, we're just a small team inside a huge company. I don't think the TypeScript people or VSCode people are even aware of what our team is doing | 2019-02-22T11:47:00.148600 | Carl |
elmlang | general | If I can automate copying it to another location and updating the source-directories list dynamically that might work... | 2019-02-22T11:48:16.149600 | Lavon |
elmlang | general | If namedropping is the goal - there's a team at adobe that uses Elm, and Amazon AWS had a job-listing for Elm engineers too, a year or so ago. | 2019-02-22T11:49:27.150100 | Huong |
elmlang | general | You could copy the whole source directory from the read only drive to one with write access? | 2019-02-22T11:49:29.150300 | Crissy |
elmlang | general | Yeah, that's an option too. I was hoping I could just change an environment variable to make it all work, but it looks like I'll have to do more than that :confused: | 2019-02-22T11:52:05.152000 | Lavon |
elmlang | general | hi, i'm trying to build the elm compiler from its source. i tried to build it using stack, but `stack init` fails because it does not find a suitable resolver. any hints? | 2019-02-22T16:23:35.155200 | Karan |

It happens on running webpack with --development, not with --production. And it just started all of a sudden between 1 compile and the other. | 2019-02-23T04:01:00.157800 | Salvador |
elmlang | general | never mind, I deleted elm-stuff and it went away. | 2019-02-23T04:02:49.158200 | Salvador |
elmlang | general | <@Salvador> That's a compiler issue, on Github there are few threads discussing it. If it comes again and removing `elm-stuff` won't help you can try running `elm make` without `--debug` if it suits you or build elm compiler from a forked repo where this bug is fixed | 2019-02-23T04:07:33.159600 | Lynne |
elmlang | general | <@Lynne> Aha, thanks for the info. For the moment it’s compiling fine. But I’ll put it on my list. | 2019-02-23T04:08:52.160500 | Salvador |
elmlang | general | Yeah, just wondered if thers some Elm package ^^ | 2019-02-23T04:31:10.160700 | Garnet |
elmlang | general | I'm using Visual Studio Code and just started a new elm project, but I can't seem to get it to reformat my code on save like it used to in my old project. Anything in particular I need to do? I'm using the Krzysztof-Cieslak/vscode-elm extension | 2019-02-23T12:46:35.162500 | Santina |
elmlang | general | Does it format manually ? (Shift+Alt+F)
in that case it must be your settings.. there is a Format on save settings in vsCode.. There is also a timer soewhere... I found that it has to be set more than defaul 1s.. when I changed mine to 5s it works every time.. | 2019-02-23T12:52:18.164800 | Monnie |
elmlang | general | Hmm. It just doesn't seem to like my code. Compiler errors. | 2019-02-23T12:58:45.165100 | Santina |
elmlang | general | does elm compiler require a Main.elm? | 2019-02-23T12:58:50.165300 | Santina |

elmlang | general | didnt want to dive into wiring the boilerplate yet | 2019-02-23T12:59:33.165700 | Santina |
elmlang | general | not sure.. never tried without main :slightly_smiling_face: | 2019-02-23T13:00:01.165900 | Monnie |
elmlang | general | Does elm compiler require a Main.elm to exist before elm-format will function? I'm starting by writing out the shape of my data and wanted it typechecked as well as the benefit of elm-format, so i've started writing some real basic static data, but elm-format shows me compiler errors with *very* basic data that *should* compile okay | 2019-02-23T13:01:29.167300 | Santina |
elmlang | general | Compiler will compile any file you point it at. The errors are probably real | 2019-02-23T13:02:50.167800 | Dede |
