elmlang | general | anyway, yes you can do that with Elm with ports and/or web components | 2019-04-04T05:13:18.366000 | Nana |
elmlang | general | the header at the very top is a live demo | 2019-04-04T05:13:20.366200 | Fidela |
elmlang | general | Seems like a custom html element that wraps the library might be the way to go here | 2019-04-04T05:15:00.366900 | Danika |
elmlang | general | that's good to hear, so I guess we still have agency over the DOM we need to control, & could hook into Elm-generated DOM elements to draw to? e.g. a <canvas> for deck, <svg> for d3? | 2019-04-04T05:15:08.367000 | Fidela |
elmlang | general | as in <https://guide.elm-lang.org/interop/custom_elements.html> ? | 2019-04-04T05:16:05.367300 | Fidela |
elmlang | general | yes | 2019-04-04T05:16:32.367400 | Nana |
elmlang | general | good to hear, I think I will try to implement 2 POCs (one for each framework) to start with :slightly_smiling_face: thanks | 2019-04-04T05:19:07.367600 | Fidela |
elmlang | general | Aye, I’ve not used them personally so I can’t be much help but I’m quite sure this is the way to go | 2019-04-04T05:20:35.368500 | Danika |
elmlang | general | sure, I'll give that a more thorough look, thank you | 2019-04-04T05:20:59.368900 | Fidela |
elmlang | general | I might have disabled hardware acceleration for Chrome :sweat_smile: | 2019-04-04T05:22:28.369000 | Nana |
elmlang | general | You use `sysconfcpus -n 1` for CI or in general on your dev machine? | 2019-04-04T05:28:57.369300 | Lynn |
elmlang | general | everywhere | 2019-04-04T05:52:13.369600 | Florencia |
elmlang | general | Cool header! Here on Safari works smoothly :slightly_smiling_face: | 2019-04-04T05:56:03.370400 | Hoa |

elmlang | general | <https://www.meetup.com/chicago-elm/> | 2019-04-04T06:58:56.371300 | Hoyt |
elmlang | general | Is it possible to trigger a `Msg` in my `init` somehow? Or at least on program start? | 2019-04-04T08:43:12.373400 | Gertrude |
elmlang | general | I'm using elm-uuid so I can create some unique IDs for something and I'm puzzling how to pre-populate the first value so I can use it in some other update branches | 2019-04-04T08:48:41.374200 | Gertrude |
elmlang | general | Sure you can, through a `Cmd` or directly by calling `update` in `init`. | 2019-04-04T09:05:39.374800 | Antonette |
elmlang | general | I don't know elm-uuid, but I'd wager that if they require you to seed some values through side-effects, there must be a function to get a `Task` or `Cmd` you can use to initialize your model. | 2019-04-04T09:07:27.376600 | Antonette |
elmlang | general | There, look at this: | 2019-04-04T09:08:01.376800 | Antonette |
elmlang | general | <https://package.elm-lang.org/packages/danyx23/elm-uuid/latest/Uuid#uuidGenerator> | 2019-04-04T09:08:12.377100 | Antonette |
elmlang | general | I wound up doing this:
```
send : Msg -> Cmd Msg
send msg =
Task.succeed msg
|> Task.perform identity
``` | 2019-04-04T09:09:22.378400 | Gertrude |
elmlang | general | So, this is a `Generator Uuid` ; `Generator` is a type that can be used with `Random.generate` <https://package.elm-lang.org/packages/elm-lang/core/latest/Random#generate> to give you a `Cmd msg` that gets a value of the type the `Generator` provides (in this case a `Uuid`). | 2019-04-04T09:10:07.379300 | Antonette |
elmlang | general | as it turns out I can't use UUIDs for this anyway. XD | 2019-04-04T09:10:59.380100 | Gertrude |
elmlang | general | I need instead to somehow make unique integer IDs. :stuck_out_tongue: | 2019-04-04T09:11:15.380700 | Gertrude |
elmlang | general | Well, at least now you know how to get one when needed :wink: | 2019-04-04T09:11:16.380800 | Antonette |
elmlang | general | Depending on how unique you want your ids to be, a `Generator Int` could do the trick. | 2019-04-04T09:13:08.382600 | Antonette |
elmlang | general | <https://package.elm-lang.org/packages/elm-lang/core/latest/Random#int> | 2019-04-04T09:13:36.382800 | Antonette |
elmlang | general | Yeah. The issue is I have this list of "Entries" and I need to make sure that when I create a new one as a placeholder, I need to give it an id that doesn't match any of the others. | 2019-04-04T09:14:41.384600 | Gertrude |
elmlang | general | With a `Generator` however, there is always a slight chance of picking the same number twice, so it might be a good idea to not just blindly accept any number it spits out, or do something a bit more unique-y like maintaining a list of available ideas in which you pluck one each time, and maybe add one back once you've... | 2019-04-04T09:14:56.385200 | Antonette |
elmlang | general | Fortunately, I have the ability to query for the latest entry, so I will just grab that and add one. | 2019-04-04T09:15:01.385400 | Gertrude |
elmlang | general | It's SQL sequential IDs so this should work, since I don't actually even send that ID back to the backend, it's just there to prevent edit collisions | 2019-04-04T09:15:46.386700 | Gertrude |
elmlang | general | The only downside to this plan is when you reach the highest possible `Int` ; in which case the "recyclable" list of available ids may do the trick. | 2019-04-04T09:15:52.387000 | Antonette |
elmlang | general | If you want to prevent edit collision, I'd advise you use a way to distinguish "persisted" ids from "draft" ids. | 2019-04-04T09:16:47.387800 | Antonette |
elmlang | general | (like an `Id x y` type: `type Id x y = Draft x | Persisted y`) | 2019-04-04T09:17:36.388900 | Antonette |
elmlang | general | yeah. currently the largest ID is in the 1mil range, and we accrue about ~500 new IDs per day. | 2019-04-04T09:19:43.389800 | Gertrude |
elmlang | general | Then the `type Id x y = Draft x | Persisted y` might be just the trick. You don't have to start your draft increment from the highest know ID, and you have a way to easily distinguish between persisted and draft elements. | 2019-04-04T09:21:03.391200 | Antonette |
elmlang | general | Hmm. Could do. | 2019-04-04T09:21:32.391400 | Gertrude |
elmlang | general | but on the flipside, it will, at present usage, take over 11,000 years to hit the ID cap of an Elm Int max size. | 2019-04-04T09:23:24.392500 | Gertrude |
elmlang | general | each entry is also specific to a date, so it only has to be unique against other entries on that date, which further prevents collisions. I've probably been over thinking this. | 2019-04-04T09:27:42.393600 | Gertrude |
elmlang | general | As long as you don't get oddities from an id being set on a draft while an element is persisted in the database with the same id, you should be fine I think. | 2019-04-04T09:29:26.394900 | Antonette |
elmlang | general | Yeah. When new entries are saved we don't send the ID. | 2019-04-04T09:29:58.395200 | Gertrude |
elmlang | general | and saving an entry triggers a refresh response of the entire list of entries from the backend, so that they once again reflect whatever's in the data base. | 2019-04-04T09:30:46.396300 | Gertrude |
elmlang | general | Then my advice is: don't overthink :wink: you'll still be able to change it later if you need something more robust anyways. | 2019-04-04T09:31:19.396900 | Antonette |
elmlang | general | Luke got me this list <https://www.meetup.com/topics/elm-programming/all/> which is decent! | 2019-04-04T09:48:52.397100 | Marcellus |
elmlang | general | just now I learned a thing: a Msg is sometimes a function and sometimes a value, and so Elm's type inference will assume the latter if you try to pass one as a generic value. | 2019-04-04T09:51:35.398600 | Gertrude |
elmlang | general | So if you have a message `EditEntry String Entry`, and you pass `EditEntry` to a function that expects a `msg` generic type variable, it will not realize that `EditEntry` is a constructor, and so if you then try to give it arguments it complains that it is not a function. | 2019-04-04T09:53:01.400300 | Gertrude |
elmlang | general | You have to make explicit that you're taking a constructor function for a msg: `(String -> Entry -> msg)` will work. | 2019-04-04T09:53:41.401100 | Gertrude |
elmlang | general | The way I see it is that `msg` is a generic value/function/whatever for Elm. If you use `Msg` the compiler can be more precise | 2019-04-04T09:54:44.401900 | Hoa |
elmlang | general | makes sense ? | 2019-04-04T09:55:00.402300 | Hoa |
elmlang | general | yeah. In this case I have not yet refactored such that I can refer to Msg directly in the function without cyclic dependency. This may be a good moment to fix that. | 2019-04-04T09:55:22.402800 | Gertrude |
elmlang | general | I have this "non optimal" use case where i would like to call java code from elm. I found "TeaVM" that lets you compile java to .js. So i guess it would be doable with elm ports. But, i wonder if theres an even better solution? | 2019-04-04T10:04:04.404800 | Carter |
elmlang | general | Java code? You're running it on the backend? | 2019-04-04T10:05:59.405100 | Niesha |
elmlang | general | Just make it a REST API call. | 2019-04-04T10:06:18.405600 | Niesha |
elmlang | general | yeah that too. But i would like to call java code clientside | 2019-04-04T10:06:24.405800 | Carter |
elmlang | general | How would you run Java on the browser? | 2019-04-04T10:06:37.406300 | Niesha |
elmlang | general | Well, thats the thing - i dont want to do that | 2019-04-04T10:06:40.406400 | Carter |
elmlang | general | Theres that TeaVM. I compiles java to js. | 2019-04-04T10:07:03.406900 | Carter |
elmlang | general | so through elm ports id be able to call it | 2019-04-04T10:07:16.407200 | Carter |
elmlang | general | its just one function but involves quite a bit of types | 2019-04-04T10:08:04.407600 | Carter |
elmlang | general | (classes/intefaces as java calls them) | 2019-04-04T10:08:18.408000 | Carter |
elmlang | general | <@Carter> sounds like you want a fork of TeaVM (or in fact plain GWT) that transpiles to Elm directly... | 2019-04-04T10:12:59.408700 | Corinne |
elmlang | general | Note their docs though:
> If you are a JavaScript developer who is satisfied with JavaScript, TypeScript or even elm, you probably won’t need TeaVM. | 2019-04-04T10:13:35.409400 | Corinne |
elmlang | general | well, i need to share java code between server and client | 2019-04-04T10:15:00.410300 | Carter |
elmlang | general | I agree with <@Niesha> here - API is the way | 2019-04-04T10:17:07.410700 | Corinne |
elmlang | general | (unless you want to use a Java Applet of course :laughing: ) | 2019-04-04T10:17:59.411000 | Corinne |
elmlang | general | Hey folks | 2019-04-04T10:35:57.411300 | Willodean |
elmlang | general | I am back writing Elm once again! | 2019-04-04T10:36:06.411700 | Willodean |
elmlang | general | I wrote a Modal yesterday and could use feedback on the approach | 2019-04-04T10:37:32.412400 | Willodean |
elmlang | general | I used the krisjenkins style type for the Modal | 2019-04-04T10:37:54.413000 | Willodean |
elmlang | general | And it worked fine. I had a button in the UI that sends a message with my Modal type inside | 2019-04-04T10:38:27.414100 | Willodean |
elmlang | general | Problem is, it doesn't sync with the model after it fires the first time | 2019-04-04T10:38:53.414900 | Willodean |
elmlang | general | So I end up with something like this | 2019-04-04T10:39:07.415300 | Willodean |
elmlang | general | ```
type Model = Model
{ ...stuff
, modalState = Toggle
, modalView = Model -> Modal Msg
}
type Msg
= ...stuff
| OpenModal (Model -> Modal Msg)
| CloseModal
``` | 2019-04-04T10:40:09.417100 | Willodean |
elmlang | general | Which feels very unElm | 2019-04-04T10:40:45.417500 | Willodean |
elmlang | general | It works for now, but I would very much appreciate a suggestion | 2019-04-04T10:44:57.419600 | Willodean |
elmlang | general | is it generally necessary to expose anything but `main` from your `Main` module? | 2019-04-04T10:46:26.420100 | Gertrude |
elmlang | general | No, you should be able to expose just `main` | 2019-04-04T10:47:55.420200 | Carman |
elmlang | general | I thought so. was wondering why I was bothering to export anything else but I think it's just something elm-format did | 2019-04-04T10:51:20.420400 | Gertrude |
elmlang | general | if you want to use function from your Main module in the repl, you'll need to expose them :slightly_smiling_face: | 2019-04-04T10:54:31.420700 | Sharon |
elmlang | general | That is a problem. I think we need some more information to figure out why | 2019-04-04T11:02:10.421000 | Sharon |
elmlang | general | Is it maybe possible to share an example on <http://ellie-app.com/> ? | 2019-04-04T11:03:34.421200 | Sharon |
elmlang | general | :wave: Hi! Until Monday, I’d never written any code to put pixels on a website, only backend data engineering work. I went through the Elm tutorial and got from zero ( + only a bit of FP experience, though lots of interest) to making a test site that displays random emoji (wheee, types) on click in one day! I’m so glad... | 2019-04-04T12:18:47.424700 | Diedre |
elmlang | general | Hi, I when running `elm install mpizenberg/elm-debounce` I consistently get the following error
```-- CORRUPT JSON ----------------------------------------------------------------
The elm.json for elm-community/list-extra 2.0.0 got corrupted somehow.
I removed it from my file cache, so if it was some transient error ... | 2019-04-04T12:48:34.427200 | Jae |
elmlang | general | One thing I noticed is that <https://package.elm-lang.org/packages/mpizenberg/elm-debounce/3.0.2/> exists on the package site but if you search "elm-debounce" it doesn't get listed | 2019-04-04T12:49:19.427300 | Jae |
elmlang | general | That's because that version is not updated for Elm 0.19 | 2019-04-04T12:49:55.427500 | Carman |
elmlang | general | I thought 0.18 packages weren't listed at all on the 0.19 package site? | 2019-04-04T12:50:47.427800 | Jae |
elmlang | general | They are excluded from the search results | 2019-04-04T12:51:22.428100 | Carman |
elmlang | general | but if you have a direct link you can still reach it | 2019-04-04T12:51:33.428300 | Carman |
elmlang | general | >>> I do not have the time to update it to elm 0.19 with the modifications I wished in response to issues #5 and #6 (removing functions and state monad, move functionalities to update instead of view).
You will probably find what you need with Gizra/elm-debouncer. | 2019-04-04T12:51:45.428500 | Carman |
elmlang | general | from the README | 2019-04-04T12:51:49.428700 | Carman |
elmlang | general | Oops, this whole time I thought there was a separate domain for 0.18 packages | 2019-04-04T12:52:30.428900 | Jae |
elmlang | general | The easiest way to check if a package supports 0.19 is to look it up on GitHub. If it has an `elm.json` then it's 0.19. If it has an `elm-package.json` then it's 0.18 or older | 2019-04-04T12:53:23.429300 | Carman |
elmlang | general | Alright | 2019-04-04T12:53:31.429500 | Jae |
elmlang | general | Should I still open a github issue for the error message though?
```-- CORRUPT JSON ----------------------------------------------------------------
The elm.json for elm-community/list-extra 2.0.0 got corrupted somehow.
...```
is not very helpful! | 2019-04-04T12:54:02.429700 | Jae |
elmlang | general | Is `Debug` the only way to cause a side-effect without a `Cmd`? | 2019-04-04T14:34:03.431400 | Leoma |
elmlang | general | Pretty much. | 2019-04-04T14:34:21.431600 | Niesha |
elmlang | general | perhaps causing a javascript `RangeError` also qualifies | 2019-04-04T14:35:45.432200 | Virgie |
elmlang | general | through unbounded recursion | 2019-04-04T14:35:52.432500 | Virgie |
elmlang | general | No, you can also do the trick with js proxies | 2019-04-04T14:37:40.433200 | Kris |
