elmlang | general | [Not sure if this is the right channel] Hello all, I am trying to use `"mdgriffith/style-elements": "5.0.1"` package while also already using ` "mdgriffith/elm-ui": "1.1.0"` for my UI. the only reason for using ` mdgriffith/style-element` is the support for `Element.Attributes` for things like `percent` . however when I have both the packages i get the below error ```The Main module has an ambiguous import:
import Element.Keyed
I found multiple module with that name though:
exposed by mdgriffith/style-elements 5.0.1
exposed by mdgriffith/elm-ui 1.1.0
It looks like the name clash is in your dependencies, which is out of your
control. Elm does not support this scenario right now, but it may be worthwhile.
Please open an issue describing your scenario so we can gather more usage
information!```
Any help would be much appreciated | 2019-04-15T17:00:10.228800 | Mirtha |
elmlang | general | You cannot use both packages, they are conflicting.
Can't you use <https://package.elm-lang.org/packages/mdgriffith/elm-ui/latest/Element#fillPortion> instead of percents? | 2019-04-15T17:05:46.230100 | Velia |
elmlang | general | aaahhhhh. Thank you | 2019-04-15T17:06:20.231000 | Mirtha |
elmlang | general | <@Mirtha> Isn't style-elements the old version of elm-ui? That would explain the namespace conflict. | 2019-04-15T17:06:24.231100 | Dayna |
elmlang | general | Thanks <@Dayna> | 2019-04-15T17:07:06.231700 | Mirtha |
elmlang | general | Yes, there are actually three versions:
- elm-ui
- style-elements
- stylish-elephants | 2019-04-15T17:09:34.231800 | Velia |
elmlang | general | A way of implementing “holes” a la Idris in Elm. | 2019-04-15T17:21:25.232100 | Jana |
elmlang | general | Anyone have experience (or insight) in something like this? Clicking the various code locations in the error logs here leads me to functions like Dict.get and Dict.map.
This only happens in Chrome, not in Firefox. Based on issues like <https://github.com/elm/core/issues/986> I figured it was fixed in Elm 0.19 but I’m getting this issue even after upgrading to 0.19. | 2019-04-15T19:20:08.232400 | Vonda |
elmlang | general | <@Vonda> that issue was fixed, but you'll get this error for other things that use deep recursion | 2019-04-15T19:23:52.234900 | Earlean |
elmlang | general | so should i just be looking through my elm code for any recursion that i can improve? | 2019-04-15T19:26:40.235300 | Vonda |
elmlang | general | or is there a more streamlined way to find the actual source of the issue | 2019-04-15T19:26:58.235600 | Vonda |
elmlang | general | also worth noting that i only randomly got this issue one day, when the previous day it worked fine. i’ve entered a lot of data into the database over the months, clearly on that day i reached the limit for this recursion issue | 2019-04-15T19:28:06.236600 | Vonda |
elmlang | general | additionally worth noting that building the app and loading that built version avoids this issue. i only get it when locally deploying in dev mode | 2019-04-15T19:28:48.237100 | Vonda |
elmlang | general | Oh, it might be the Elm debugger | 2019-04-15T19:29:48.237600 | Earlean |
elmlang | general | It tends to struggle as your model gets larger | 2019-04-15T19:30:13.238100 | Earlean |
elmlang | general | Try compiling without `--debug` | 2019-04-15T19:30:49.238600 | Earlean |
elmlang | general | yeah compiling without `--debug` fixed it | 2019-04-15T19:32:55.238900 | Vonda |
elmlang | general | good to know. should i just avoid using the debugger then? or is there a solution | 2019-04-15T19:33:44.239300 | Vonda |
elmlang | general | If I am writing a library where I depend on a couple other libraries, but I need to expose/re-export the data types for the user, how should I go about doing that? I also don't want the user to have to manually install several libraries just to use mine, and then have to add a ton of import declarations. I thought about including a subset of these libraries in my own, or writing my own implementation to reduce dependencies and allow better integration with my library code. | 2019-04-15T22:47:16.242300 | Isaiah |
elmlang | general | <@Isaiah> Not sure if you can re-export imported types, might need to write type aliases for them and export that. But w/ the current compiler version, I think that'll break the debugger for library consumers. | 2019-04-15T22:51:18.243400 | Earnest |
elmlang | general | Type alias are what you want. But note that there isn't a way to re-export constructors | 2019-04-15T22:52:31.244600 | Earlean |
elmlang | general | That's the problem then, because the user needs to have access to the constructors | 2019-04-15T22:56:16.245100 | Isaiah |
elmlang | general | the libraries are small (single file, under 1k loc) so including them in my own should be fine, and also give me a chance to fix any issues and remove code I don't need | 2019-04-15T22:57:11.246000 | Isaiah |
elmlang | general | I'm seeking advice on how to make a single javascript function call. Basically it needs to be done once, but it doesn't matter if it's called more often. I know you can't make javascript calls in Elm (anymore), but this library isn't likely to be package anytime soon. Any tips on how to do this with Elm 0.19? | 2019-04-15T23:37:15.247800 | Erlene |
elmlang | general | The javascript function itself is pure. And it would be so handy if I could simply call it from Elm. | 2019-04-15T23:37:44.248400 | Erlene |
elmlang | general | Your options are either ports, something like <https://medium.com/@jjant/making-elm-unsafe-cc6435495af2> or the proxy trick. | 2019-04-15T23:38:52.249400 | Kris |
elmlang | general | <@Erlene> why is it called only once? Can you call it before you start Elm? | 2019-04-15T23:39:44.250700 | Earlean |
elmlang | general | <@Earlean> yes, I possibly could, but the problem is I need its value somewhere deep inside. Passing that all the time is annoying. | 2019-04-15T23:40:54.251400 | Erlene |
elmlang | general | Basically what this is is calculating the size of the horizontal scrollbar. | 2019-04-15T23:41:10.251800 | Erlene |
elmlang | general | The javascript does that by inserting an element, measuring the scrollbar, and removing the element from the DOM again | 2019-04-15T23:41:33.252300 | Erlene |
elmlang | general | Not something I can see myself doing in Elm. And it needs to be done once, not all the time I'm drawing elements that need to know this stuff. | 2019-04-15T23:41:55.252800 | Erlene |
elmlang | general | <@Kris> hmm, replacing code won't work for me, although it's an interesting technique. What's the proxy trick? | 2019-04-15T23:42:55.253500 | Erlene |
elmlang | general | Seems like something you compute in JS, pass as a Flag, and store on your Model so that it’s available throughout…? | 2019-04-15T23:47:15.254200 | Dede |
elmlang | general | <@Dede> yeah, that might be the cleanest, although getting it where it needs to be isn't :slightly_smiling_face: | 2019-04-15T23:51:40.254800 | Erlene |
elmlang | general | <@Erlene> <https://ellie-app.com/5gTZKqtg9HTa1> | 2019-04-15T23:58:06.255100 | Kris |
elmlang | general | that's the gist of it | 2019-04-15T23:58:09.255400 | Kris |
elmlang | general | Yeah, that's basically passing it as a flag isn't it? | 2019-04-16T00:00:21.255800 | Erlene |
elmlang | general | I need just the value once, so the ability to call it as a function isn't needed. | 2019-04-16T00:00:41.256400 | Erlene |
elmlang | general | Perhaps I simply need a Kernel module... | 2019-04-16T00:00:49.256700 | Erlene |
elmlang | general | I feel like if it’s hard to get data from your Model to some part of your code, something’s gotten overly convoluted. | 2019-04-16T00:02:02.257200 | Dede |
elmlang | general | I realize I am entirely unaware of your design constraints, however. | 2019-04-16T00:02:19.257500 | Dede |
elmlang | general | <@Dede> normally I'd agree, but this is a library used by others. So if I can avoid having to pass this in, but have the value simply available, that would make it easiest. | 2019-04-16T00:06:17.258500 | Erlene |
elmlang | general | Could they pass it in once? | 2019-04-16T00:06:47.259200 | Dede |
elmlang | general | Elm really should have a system for "values that are constant for the life of the program but aren't known at compile time" | 2019-04-16T00:06:56.259500 | Earlean |
elmlang | general | flags really should be that system | 2019-04-16T00:07:21.260300 | Earlean |
elmlang | general | I’m thinking something very roughly where you `init` your `Widgets` library and then the API is actually returned in a record that you can store on the Model and call directly.
```
module Widgets exposing (init, Widgets)
type alias Widgets = {
button: ButtonOptions -> Button,
...
}
init: Int -> Widgets
...
``` | 2019-04-16T00:09:28.262800 | Dede |
elmlang | general | This goes against the advice that says never store closures on the Model, but given that the arguments are immutable, I think it’s OK. | 2019-04-16T00:10:02.263600 | Dede |
elmlang | general | that's the common solution for things like this in functional languages, but then use lose the benefits of `import` | 2019-04-16T00:10:51.264600 | Earlean |
elmlang | general | `import` is, "give me direct access to these global constants in this module" | 2019-04-16T00:11:32.265300 | Earlean |
elmlang | general | it would be great if you could do the same but for runtime constants | 2019-04-16T00:11:54.265700 | Earlean |
elmlang | general | Fair enough. | 2019-04-16T00:12:03.265900 | Dede |
elmlang | general | eg. `import flags` and `flags` gives you access to the `flags` value passed in to `init` | 2019-04-16T00:12:50.267000 | Earlean |
elmlang | general | yeah having to pass everything around is horrible | 2019-04-16T00:15:58.268200 | Kris |
elmlang | general | Building a program without thinking where the facts come from and how they're passed around makes the program harder to refactor when the program grows and becomes more configurable. I'd prefer better systems for passing around information, instead of changing the way imports work or anything like that. Haskell has the Reader type, but it could be something completely different. | 2019-04-16T00:25:17.270600 | Rosanne |
elmlang | general | but the same could be said for `import` | 2019-04-16T00:26:00.271000 | Earlean |
elmlang | general | never use `import` only ever receive functions as parameters. | 2019-04-16T00:28:08.271800 | Earlean |
elmlang | general | which is great advice and gives you great seams for future changes, but it's a real pain | 2019-04-16T00:31:15.272600 | Earlean |
elmlang | general | Reader doesn’t improve the situation that much in that regards | 2019-04-16T00:35:23.273800 | Kris |
elmlang | general | It’s still literally the same as passing a parameter, with the annoyance of having to do it even for constants | 2019-04-16T00:35:52.274800 | Kris |
elmlang | general | Hello! Is there a way to access response headers using <https://package.elm-lang.org/packages/ohanhi/remotedata-http/latest/> by <@Bert>? My program is interacting with GitHub API (v3) and the pagination data is exposed as headers. Do I need to use plain `elm/http` with `expectStringResponse`? | 2019-04-16T01:48:40.277600 | Dorsey |
elmlang | general | Yep, you will | 2019-04-16T01:53:04.277900 | Earlean |
elmlang | general | Thanks! | 2019-04-16T01:57:24.278200 | Dorsey |
elmlang | general | Can elm import JS files? | 2019-04-16T03:13:41.278500 | Carrie |
elmlang | general | Not really; you can interact with native JS lib through ports | 2019-04-16T03:14:45.279100 | Allyn |
elmlang | general | <https://guide.elm-lang.org/interop/ports.html> | 2019-04-16T03:15:17.279300 | Allyn |
elmlang | general | Oh, I see.thanks | 2019-04-16T03:23:05.280000 | Carrie |
elmlang | general | But I saw the phrase "import Native. Ace" at <https://github.com/DenisKolodin/elm-ace/blob/master/src/Ace.elm>. Isn't he importing the Ace. JS file? | 2019-04-16T03:26:59.280300 | Carrie |
elmlang | general | There used to be so called native modules - specially written JS files which one could "import" and use within Elm app, but they are gone in 0.19 | 2019-04-16T03:34:51.281400 | Lynne |
elmlang | general | The example you found will only work in Elm 0.18 | 2019-04-16T03:35:07.281700 | Lynne |
elmlang | general | Oh, that's it. | 2019-04-16T03:37:13.281900 | Carrie |
elmlang | general | thanks | 2019-04-16T03:37:25.282200 | Carrie |
elmlang | general | This discussion is relevant:
<https://discourse.elm-lang.org/t/how-to-re-export-values-and-types-from-a-module/3142> | 2019-04-16T03:39:29.282300 | Velia |
elmlang | general | Hey! I'm using `AssocList` imported as `Dict`, but then one of the other modules (Http) returns a standard `Dict`. How can I avoid naming clashes? Preferably I would just convert the `Dict` into `AssocList.Dict`. Is there something like `AssocList.fromDict`? | 2019-04-16T04:44:44.285600 | Dorsey |
elmlang | general | For the name clash, you cannot import it as `Dict` if you already use `Dict` in the same module.
For the conversion:
```
Dict.toList dict
|> AssocList.fromList
``` | 2019-04-16T04:47:04.286200 | Velia |
elmlang | general | Yeah. That's where I'm coming from. | 2019-04-16T04:47:31.286400 | Dorsey |
elmlang | general | I thought there may be some clever way to avoid importing `Dict` at all. | 2019-04-16T04:48:04.286600 | Dorsey |
elmlang | general | I think you can put the conversion function in a another module, so you can directly convert without importing Dict (if you don't need it in signatures) | 2019-04-16T04:50:08.286800 | Velia |
elmlang | general | But it's not included in `AssocList` itself. | 2019-04-16T04:51:05.287000 | Velia |
elmlang | general | Sure. I'll just do `import Dict as StandardDict` for now. It adds to the noise, but separate module would add even more IMO. | 2019-04-16T04:51:06.287200 | Dorsey |
elmlang | general | I changed to using it like `import AssocList as Assoc` and `Assoc.get` etc. | 2019-04-16T04:51:29.287400 | Nana |
elmlang | general | Oh, that's nice! I'll do it too <@Nana>. | 2019-04-16T04:52:05.287600 | Dorsey |
elmlang | general | I found it a bit confusing to "impersonate" a data type like that, not very explicit | 2019-04-16T04:53:16.287800 | Nana |
elmlang | general | Yeah, good point. I hope in some future realease of Elm standard Dict will have the same properties as AssocList.Dict and the whole confusion will go away. | 2019-04-16T04:54:21.288200 | Dorsey |
elmlang | general | Hey all, I'm writing a parser for template strings (for example `there are {numberOfPeople} online`) and I want to extract the placeholder name, what I've come up is:
```
succeed identity
|. chompUntil "{"
|. symbol "{"
|= getChompedString (chompWhile (\c -> c /= '}'))
```
but it seems kind of convoluted. Is there any way to make it simpler? | 2019-04-16T05:03:15.290100 | Dayna |
elmlang | general | What can I do to convert my current 0.19 version of elm to 0.18 version? | 2019-04-16T05:33:59.290400 | Carrie |
elmlang | general | look at the docs for npm install | 2019-04-16T05:40:41.290900 | Rosario |
elmlang | general | `npm install [email protected]` or someting | 2019-04-16T05:41:11.291200 | Rosario |
elmlang | general | Hello! Would you mind sharing the slackbot (the one that prompts us to be inclusive in the way we communicate) settings? :slightly_smiling_face: | 2019-04-16T05:43:44.293000 | Cyndy |
elmlang | general | `npm show elm` shows you the tags. You want `npm install [email protected]` | 2019-04-16T05:43:47.293300 | Rosario |
elmlang | general | It does not look convoluted to me, why do you think so?
You could use:
```
succeed identity
|. chompUntil "{"
|. symbol "{"
|= getChompedString (chompUntil "}")
|. symbol "}"
```
But it's not that different.
As an aside, beware this bug (position is consumed, not the string):
<https://github.com/elm/parser/issues/20> | 2019-04-16T05:49:36.293400 | Velia |
elmlang | general | You could use identity as well, something like that :
```
[ "element" ] |>
if bool then (::) "plus" else identity
``` | 2019-04-16T05:54:23.293700 | Syble |
elmlang | general | I think <#C3FKL0A8H|admin-help> is where you might get it | 2019-04-16T08:33:50.294700 | Bert |
elmlang | general | hi, does anyone here run `npm audit`? currently seeing all of these issues: | 2019-04-16T08:52:15.295600 | Nancy |
elmlang | general | Yeah, the team's aware. It's due to a dependency of `binstall`, so the solution needs to bubble up | 2019-04-16T09:07:39.296000 | Huong |
elmlang | general | will this need a new release of the affected packages? | 2019-04-16T09:13:14.296300 | Nancy |
elmlang | general | Morning folks. If I have a bunch of html that is not really changing except for a very small, almost single div (think removing a class from one span and adding the class to another), would making everything else keyed have a useful impact on the performance of the vdom diffing? Say if the keys were at the highest level, so it would know it didn’t have to go further down to compare? | 2019-04-16T10:26:56.298200 | Hoyt |
elmlang | general | Is it a function that returns HTML or is a literal? | 2019-04-16T10:28:13.298500 | Sabra |
elmlang | general | function | 2019-04-16T10:29:09.298800 | Hoyt |
elmlang | general | Returning `Html msg` | 2019-04-16T10:29:16.299000 | Hoyt |
elmlang | general | Thanks! | 2019-04-16T10:29:39.299300 | Cyndy |
