elmlang | general | Right now, it says:
```
-- TYPE MISMATCH ----------------------------------------- src/SearchResults.elm
Something is off with the 1st branch of this `case` expression:
209| callback (Results newResults)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This `callback` call produces:
msg
But the type annotation on `httpResponseToSearchResults` says it should be:
SearchResults
Hint: Your type annotation uses type variable `msg` which means ANY type of
value can flow through, but your code is saying it specifically wants a
`SearchResults` value. Maybe change your type annotation to be more specific?
Maybe change the code to be more general?
Read <https://elm-lang.org/0.19.0/type-annotations> for more advice!
``` | 2019-02-14T19:14:38.372900 | Marcus |
elmlang | general | I named the `(SearchResults -> msg)` parameter `callback`. Probably not the right name, but that's what it is right now. | 2019-02-14T19:15:31.373900 | Marcus |
elmlang | general | I think the signature of httpResponseToSearchResults was off. | 2019-02-14T19:16:36.374300 | Marcus |
elmlang | general | I just changed it to:
```
httpResponseToSearchResults : (SearchResults -> msg) -> Result Http.Error SearchResultsData -> msg
httpResponseToSearchResults callback result =
...
```
And that made the error go away. | 2019-02-14T19:18:00.375200 | Marcus |
elmlang | general | Question though, is there a more idiomatic name than `callback` for that parameter? | 2019-02-14T19:18:18.375700 | Marcus |
elmlang | general | Or, a more idiomatic way to indicate what should be called, in the end? | 2019-02-14T19:18:44.376400 | Marcus |
elmlang | general | It's common to call a function intended to produce a msg value `toMsg` | 2019-02-14T19:19:28.377400 | Earlean |
elmlang | general | That makes sense. | 2019-02-14T19:20:01.377800 | Marcus |
elmlang | general | Gotta run. I'm getting close. Thanks for everyone's help. | 2019-02-14T19:25:32.378100 | Marcus |
elmlang | general | How can I convert a `input [typ_="date"][]` value to a Posix? Seems like elm gets the value as a string when you use onInput (in the format of "YYYY-MM-DD") | 2019-02-14T21:17:44.379100 | Nga |
elmlang | general | <https://package.elm-lang.org/packages/elm/time/latest/Time> -- I'm seeing nothing here for converting a string or pieces of a string to a Posix | 2019-02-14T21:18:02.379400 | Nga |
elmlang | general | The old elm stuff has this: <https://package.elm-lang.org/packages/elm-lang/core/latest/Date> -- I can't find a Date package in the latest core. | 2019-02-14T21:18:31.379800 | Nga |
elmlang | general | <@Nga> yep, `elm/time` doesn't provide any parsers for handling string encoded date formats. There are other packages for parsing strings in to `Time.Posix`. | 2019-02-14T21:30:04.381100 | Earlean |
elmlang | general | <@Earlean> when you say "other packages" do you mean stdlib, or third party? | 2019-02-14T21:33:02.381600 | Nga |
elmlang | general | I'm assuming you mean third-party, like this: <https://package.elm-lang.org/packages/rtfeldman/elm-iso8601-date-strings/latest/>
It's a shame that I have to rely on outside packages for something like this :disappointed: Shouldn't Elm support the date input type more thoroughly, and so give us a way to convert a iso8601 to posix? What am I missing here? Seems like an odd decision to exclude this functionality. | 2019-02-14T21:36:38.383200 | Nga |
elmlang | general | <@Nga> if you scroll down to the 'iso8601' section of the Readme you can read the justification for why it's not supported. | 2019-02-14T21:41:42.383900 | Earlean |
elmlang | general | <https://package.elm-lang.org/packages/elm/time/latest/> | 2019-02-14T21:41:42.384100 | Earlean |
elmlang | general | <@Earlean> Thanks. I'd say that argument makes a lot of sense if there weren't such a thing as a date input which has very vast browser support. It would also make it easier for people to create custom datepickers. Even just a Posix constructor would be a sufficient work-around, and then people could parse the strings themselves and feed ints to a constructor. | 2019-02-14T21:47:35.387000 | Nga |
elmlang | general | is anyone building a comprehensive widget lib for elm? | 2019-02-14T22:19:01.387800 | Lupita |
elmlang | general | scrolling thru vue and react and omg so much there | 2019-02-14T22:19:36.388200 | Lupita |
elmlang | general | <http://package.elm-lang.org|package.elm-lang.org> turns up a few hits on the term ‘widget’. Is there something specific you’re looking for? | 2019-02-14T22:47:19.390300 | Dede |
elmlang | general | no really specific, just doesn't seem to maturing like you would think | 2019-02-14T22:48:55.391700 | Lupita |
elmlang | general | A huge number of widget implementations aren’t really needed anymore as the web standards have improved. E.g., flexbox has solved a number of problems. It’s often not that hard to just… write the exact thing you want. | 2019-02-14T22:49:52.392800 | Dede |
elmlang | general | well yes, i write some custom vue stuff all the time. we still use vuetify and others though | 2019-02-14T22:50:35.394500 | Lupita |
elmlang | general | Now, elm-ui is a fascinating package that I personally love — it abstracts away html entirely and presents a rather nicer design language to work with. | 2019-02-14T22:50:36.394700 | Dede |
elmlang | general | i need to mess with it more. been following this article <https://medium.com/@mickey.vip/an-approach-to-nested-reusable-view-functions-in-elm-a1531b9abaf3> | 2019-02-14T22:51:01.395100 | Lupita |
elmlang | general | Elm has a very small community compared to Vue or React, there was previously a package for 'Material Design Lite' but it wasn't updated for Elm 0.19 and 'Material Design Lite' was discontinued. | 2019-02-14T22:52:02.396100 | Earlean |
elmlang | general | sure i understand it's still relatively new | 2019-02-14T22:52:53.396800 | Lupita |
elmlang | general | so going back to that article, would you mind if i ask a few questions? | 2019-02-14T22:54:08.397400 | Lupita |
elmlang | general | the code that does event.onInput how do i know what parameters it's going to throw if i'm not familiar with that | 2019-02-14T22:56:20.399800 | Lupita |
elmlang | general | I’m happy to take a shot at answers. I’m a relative newbie and not core, there are people (e.g. @ jessta) who can give much more informed answers too if they’re around. | 2019-02-14T22:56:21.399900 | Dede |
elmlang | general | The core documentation is generally pretty good: <https://package.elm-lang.org/packages/elm/html/latest/Html-Events#onInput> | 2019-02-14T22:57:13.400400 | Dede |
elmlang | general | So you’d start by seeing that it’s called `Evt.onInput` in the file, scroll to the top to see that `Evt` is defined by `import Html.Events as Evt`, then go look for the docs on the `Html` package by searching <https://package.elm-lang.org/> for `Html` | 2019-02-14T22:58:44.401300 | Dede |
elmlang | general | that article is quite involved but gives some good info | 2019-02-14T23:14:01.402800 | Lupita |
elmlang | general | If you haven’t written Elm yet, the article’s a bit of a deep-end dive. | 2019-02-14T23:15:03.403100 | Dede |
elmlang | general | well makes sense and the partial application of the toInt with default waiting for the string parameter is cool but not easy to get until you look at it several time | 2019-02-14T23:16:00.404100 | Lupita |
elmlang | general | maybe i should write my vue application that does a table sort by clicking on a column heard in elm and see how far i get | 2019-02-14T23:20:40.404900 | Lupita |
elmlang | general | There was an elm-sortable-table package in 0.18 that forked in 0.19 — there are at least 3 forks on packages, e.g. <https://package.elm-lang.org/packages/NoRedInk/elm-sortable-table/latest/> | 2019-02-14T23:22:36.405600 | Dede |
elmlang | general | yeah but more interested in figuring out the pieces, this has a sort, click handlers that pass to the sort and a way to get json data from a website. <https://github.com/rschneiderman0123/vue-table-sort>. ofc, i know vue much better than when i wrote this. | 2019-02-14T23:24:06.407100 | Lupita |
elmlang | general | oh and has a computed function | 2019-02-14T23:25:42.407800 | Lupita |
elmlang | general | anyways, back again tomorrow | 2019-02-14T23:27:53.408700 | Lupita |
elmlang | general | hello, what field can i match this with? <https://gist.github.com/afidegnum/41ad46240fcf442b27cca862e482ee3a#file-main-elm-L460> | 2019-02-15T00:27:15.409100 | Leopoldo |
elmlang | general | i m having an error, ``` This is not a record, so it has no fields to access!
460| response.status
^^^^^^^^
This `response` value is a:
Int
But I need a record with a status field!
``` | 2019-02-15T00:27:41.409400 | Leopoldo |
elmlang | general | <@Leopoldo> the answer is the same as it was 7 hours ago. You're using `elm/http 2.0.0` but your that code was written for `elm/http 1.0.0` | 2019-02-15T00:30:41.410500 | Earlean |
elmlang | general | ```
Http.BadStatus statusCode ->
String.fromInt statusCode
``` | 2019-02-15T00:31:01.410700 | Earlean |
elmlang | general | ^ will work with `elm/http 2.0.0` | 2019-02-15T00:32:43.411200 | Earlean |
elmlang | general | ok, thanks, it works | 2019-02-15T00:34:20.411700 | Leopoldo |
elmlang | general | i will fun a test to find out | 2019-02-15T00:34:31.412000 | Leopoldo |
elmlang | general | i m finding hard to solve this nuance .. <https://gist.github.com/afidegnum/41ad46240fcf442b27cca862e482ee3a#file-main-elm-L497>
``` The 3rd element of this list does not match all the previous elements:
494| [viewHeader
495| , pg.content
496| , viewFooter ]
^^^^^^^^^^
This `viewFooter` value is a:
Route -> List (Html.Html msg)
But all the previous elements in the list are:
List (Html.Html msg)
```
Adding `Route` type signature to the other designated ones breaks the whole structure, but `viewFooter` can't go away with the *Router*
what do you suggest ? | 2019-02-15T01:04:18.414000 | Leopoldo |
elmlang | general | do you have the route at this point in time? | 2019-02-15T01:06:30.414400 | Ruthann |
elmlang | general | yes, | 2019-02-15T01:07:02.414900 | Leopoldo |
elmlang | general | from your code, looks like you can just change ln497 to `++ viewFooter model.route` no? | 2019-02-15T01:07:11.415100 | Ruthann |
elmlang | general | ok, i believe that works :slightly_smiling_face: | 2019-02-15T01:09:50.415400 | Leopoldo |
elmlang | general | It's not optimal for a custom datepicker to return an ISO-string though. Better that they return a `Date` (from the justinmimbs/date package for example, which I think most Elm datepickers are already using :slightly_smiling_face:) | 2019-02-15T03:25:39.415800 | Nana |
elmlang | general | Btw there is a ISO8601 package already, it's just not a core language library | 2019-02-15T03:28:08.416000 | Nana |
elmlang | general | Hey beautiful people and vigilant bots, I have a growing problem and don't know how to address it: my team and I started adding bits and pieces of Elm in an existing app with the ambition to join them in one glorious SPA as soon as we cover all urls. So far, so good. Except for one thing: we're using `elm-webpack-loader`, and we have a main JS file to attach all our elm programs to the nodes they're allowed to squat in the app, and *every time we save one file, all the elm files are re-compiled and added to the main JS file* which is a very long process.
So, is there a way to explain to `elm-webpack-loader` (or webpack?) that it only needs to re-build the parts that have changed and not those who aren't part of the changes? If so, how do I go about it? If not, what is your advice to turn this around? I can provide code samples but not the repo itself (and it's quite wide anyways so it'd be better if you tell me what you'd like to inspect anyways). | 2019-02-15T05:02:32.424500 | Antonette |
elmlang | general | That sounds sort of similar to the situation NoRedInk was in, when they decided to build jetpack (<https://github.com/NoRedInk/jetpack>) | 2019-02-15T05:04:24.424600 | Huong |
elmlang | general | Thanks for the lead :slightly_smiling_face: | 2019-02-15T05:05:04.424800 | Antonette |
elmlang | general | Arf :neutral_face: It looks like it doesn't handle anything expect for Elm and CoffeeScript and we're also using Stylus to make our css stylesheets. | 2019-02-15T05:08:20.425000 | Antonette |
elmlang | general | I’m using `elm-webpack-loader` and it doesn’t seem to have this issue? But I might be mistaken. | 2019-02-15T05:12:39.425200 | Agustin |
elmlang | general | `parcel` might be another option, basically 0 config, plays nice with ore processors | 2019-02-15T05:18:11.426200 | Danika |
elmlang | general | Thanks <@Danika>, I'll have a look :slightly_smiling_face: | 2019-02-15T05:27:57.426400 | Antonette |
elmlang | general | While I'm happy for you that you don't seem to encounter that problem, I have to admit this doesn't help much <@Agustin>... :wink: | 2019-02-15T05:29:03.426600 | Antonette |
elmlang | general | <@Antonette> I was confirming which package you are using? | 2019-02-15T05:29:27.426800 | Agustin |
elmlang | general | e.g. try `elm-webpack-loader` rather than `webpack-elm` | 2019-02-15T05:30:00.427000 | Agustin |
elmlang | general | Yep, I'm using `elm-webpack-loader` indeed. | 2019-02-15T05:30:08.427200 | Antonette |
elmlang | general | (and it seems I gave a false indication in my original post, my bad) | 2019-02-15T05:30:49.427400 | Antonette |
elmlang | general | Ah ok, your original post made it sound like you weren’t using it, apologies | 2019-02-15T05:30:50.427600 | Agustin |
elmlang | general | i'm also using `elm-webpack-loader` but i don't have this issue :thinking_face: | 2019-02-15T05:31:27.427900 | Lilli |
elmlang | general | Have you configured it in another way? Or are you building an SPA? (with only one elm entry point) | 2019-02-15T05:32:03.428100 | Antonette |
elmlang | general | (here's my original configuration if you see something I did wrong):
```
{
test: /\.elm$/,
exclude: [/elm-stuff/, /node_modules/],
loader: 'elm-webpack-loader?cwd=webpack/client'
}
``` | 2019-02-15T05:33:37.428300 | Antonette |
elmlang | general | I have a single entry point, a simple JS file that handles the app initialization. This file loads the main elm file and from there on, further loading is done on the Elm side | 2019-02-15T05:35:41.428600 | Lilli |
elmlang | general | ```
{
exclude: [/elm-stuff/, /env/, /node_modules/],
test: /\.elm$/,
use: {
loader: 'elm-webpack-loader',
options: { files: glob.sync("src/**/*.elm") }
}
},
``` | 2019-02-15T05:35:42.428800 | Agustin |
elmlang | general | Thanks <@Agustin>, I'll try it right away :wink: | 2019-02-15T05:37:56.429000 | Antonette |
elmlang | general | Just one thing though, I take it loading from the JS file is different with this `file` option? | 2019-02-15T05:38:42.429200 | Antonette |
elmlang | general | (the Elm compiled file to import might not be named as it was or something?) | 2019-02-15T05:39:17.429400 | Antonette |
elmlang | general | I’m still doing a `import { Elm } from './Main.elm';` in my bundle? | 2019-02-15T05:40:08.429600 | Agustin |
elmlang | general | And I take it your `Main.elm` is one in the many programs? | 2019-02-15T05:40:54.429800 | Antonette |
elmlang | general | (because my problem stems from the whole app having many programs we attach to various pages and not an SPA with only one program in a `Main.elm` file) | 2019-02-15T05:42:14.430000 | Antonette |
elmlang | general | Like, in my case, I have a `Page` directory with many `.elm` files that each have a `Program`, and in my `index.js` file I do a `require('./Pages/NameOfTheProgramIWant.elm')` for each `Program` file. | 2019-02-15T05:44:08.430200 | Antonette |
elmlang | general | So, if I do that, I'll have a "virtual" `./Main.elm` file to load that will be a compilation of all my `./Page/*.elm` files or something? (and `./Main.elm` is a convention of `elm-webpack-loader`?) | 2019-02-15T05:47:24.430500 | Antonette |
elmlang | general | Ok, so I did this:
```
{
test: /\.elm$/,
exclude: [/elm-stuff/, /node_modules/],
loader: 'elm-webpack-loader',
options: {
cwd: 'webpack/client',
files: path.resolve(glob.sync('webpack/client/Pages/**/*.elm'))
}
}
``` | 2019-02-15T05:57:26.430900 | Antonette |
elmlang | general | And my main js file has this:
```
const Elm = require("./elm/Main");
console.log(Elm);
``` | 2019-02-15T05:58:24.431100 | Antonette |
elmlang | general | And I get this from webpack:
```
ERROR in ./index.js
Module not found: Error: Can't resolve './elm/Main' in '/src/webpack/client'
``` | 2019-02-15T05:58:59.431300 | Antonette |
elmlang | general | What do you think I did wrong? | 2019-02-15T05:59:20.431500 | Antonette |
elmlang | general | Hey, how do you concatenate two strings in Elm? | 2019-02-15T07:12:41.432200 | Logan |
elmlang | general | <@Logan> `someString ++ anotherString` | 2019-02-15T07:13:45.432600 | Tamra |
elmlang | general | TIL thank you! | 2019-02-15T07:16:57.432900 | Logan |
elmlang | general | <@Antonette> where is your `elm` folder physically located compared to `index.js`? | 2019-02-15T07:43:46.433200 | Lynne |
elmlang | general | It seems like you need to `require('../../elm/Main')` instead | 2019-02-15T07:44:11.433400 | Lynne |
elmlang | general | (sorry <@Lynne> I've been away for lunch :sweat_smile:) | 2019-02-15T07:52:39.433600 | Antonette |
elmlang | general | So, here's the gist of it:
```
- webpack.config.js
- webpack/client/index.js // the base file that compiles to the final complete js file
- webpack/client/Pages/**/*.elm // the base files for elm pages live here
``` | 2019-02-15T07:54:56.433800 | Antonette |
elmlang | general | Is there a way to get cryptographically secure random number native or do I need to use a port? | 2019-02-15T07:58:54.434400 | Olimpia |
elmlang | general | :slightly_smiling_face: | 2019-02-15T07:58:57.434600 | Olimpia |
elmlang | general | there is nothing official, so I think ports would be the best solution | 2019-02-15T08:06:19.435100 | Virgie |
elmlang | general | tnx | 2019-02-15T08:10:38.435400 | Olimpia |
elmlang | general | PSA to anyone using Elm with Webpack : I managed to hack proper color highlighting of type errors back in
<https://github.com/rtfeldman/node-elm-compiler/issues/91>
been using it for a day now, and it's so much nicer :relieved:
(just edit the file in your node_modules folder)
maybe someone can figure out how to do it properly later | 2019-02-15T08:24:00.438100 | Nana |
elmlang | general | Oooooh! That's nice! | 2019-02-15T08:25:30.438300 | Antonette |
elmlang | general | Sorry <@Antonette> I misunderstood your problem, I have checked my config against multiple Elm endpoints and it is compiling both | 2019-02-15T08:25:59.438400 | Agustin |
elmlang | general | Worse it seems to make them both the same size | 2019-02-15T08:26:06.438600 | Agustin |
