there's no way to send Lists of Records between Elm apps without using a JSON decoder, right?
2019-03-05T07:05:26.462300
Nana
elmlang

If these records does not contain custom types you could probably rely on default serialization/deserialization
2019-03-05T07:07:23.462500
Lynne
elmlang

although actually I can probably just use the same decoder as for the http
2019-03-05T07:07:48.462700
Nana
elmlang

Probably, and at some point you'll want to have more control over deserialization so I would probably use some shared model even

Hi there, just a :wave: to say thanks for the feature of assets loading in elm-reactor relative to root path of the project detailed here : <https://blog.ilias.xyz/elm-reactor-and-custom-html-9e7143553807> Idk how I missed the info in the docs, but it's a really cool feature, can load images and stuff, good job

Hi folks, I encountered runtime error when I test the ‘travel planner’ example in billstclair/elm-sortable-table. The runtime “TypeError: Argument 1 (‘node’) to Node.appendChild must be an instance of Node” occurred, when clicking on ‘Rating’ column after clicking on ‘Price’ column. The gif is attached. Is this a known elm bug?

does the elm architecture still fit under the "functional reactive programming" vibe. I know pre 0.17(?) elm was all-in on FRP and that TEA emerged from that, is it safe to say that the elm architecture is a type or implementation of FRP?
2019-03-05T08:27:07.473200
Danika
elmlang

&gt; So is Elm about FRP anymore? No. Those days are over now. Elm is just a functional language that takes concurrency very seriously. And from a user's perspective, Elm is just a friendly functional language!

They are, which is why I'm trying to place TEA.

elmlang

&gt; Somebody really needs to write a "Functional Reactive Programming For Dummies" for all us autodidacts out here. Every resource I've found, even Elm, seems to assume you've gotten a Master's in CS in the last five years. Those knowledgable about FRP seem to have completely lost the ability to see the matter from the naive viewpoint, something critical to teaching, training and evangelizing. – TechZen May 4 '14 at 13:48 Basically this.

My guess is that if you're not mapping/folding over time, then it's not "real" FRP in the academic sense
2019-03-05T08:38:32.474700
Nana
elmlang

The gist of it is I'm working on my own programming language, focused on music programming. I'd like to apply TEA to this context but it's hard to talk about it without just referring to the elm docs.

Wikipedia: &gt; Functional reactive programming (FRP) is a programming paradigm for reactive programming (asynchronous dataflow programming) using the building blocks of functional programming (e.g. map, reduce, filter).
2019-03-05T08:43:34.475200
Nana
elmlang
general
by that definition TEA, React and Vue are not FRP
2019-03-05T08:43:59.475400
Nana
elmlang
general
react and vue aren't the _functional_ part
2019-03-05T08:44:56.475600
Danika
elmlang
general
But they're both built on Rxjs (at least I think react is) which definitely is frp
2019-03-05T08:45:41.475800
Danika
elmlang
general
neither uses Rxjs, Vue uses it's own Observables, and I think React just uses simple callbacks or something

2019-03-05T08:52:38.476200

You can run it in a git hook

Use a file system watcher that runs in on save?

Wont’ show back up in vscode unless that supports automatically picking up the changes tho
2019-03-05T09:22:34.480700

2019-03-05T09:22:48.481100

So thanks to <@Maida> who helped in the beginners channel I have decided to use elm’s interop as a means to solve an issue on a project I am building for a client that requires PDF creation. I think I narrowed it down to either jspdf, pdfkit or pdfmake. Wondering if anyone has had experience working with any of these and would be willing to share their opinion or recommendations

the Time module is still around but it's in its own package now: `elm/time`
2019-03-05T10:30:14.499200
Shenita
elmlang
general
but for getting update msgs it only has `Time.every` (<https://package.elm-lang.org/packages/elm/time/latest/Time#every>) which gives you a subscription rather than a one-off cmd
2019-03-05T10:31:08.500100

I just have some html that I need remove after X seconds
2019-03-05T10:35:10.501000

so Process.sleep will work

I actually played around with the extension to see what was the reason. Anyways adding `.cmd` after `elm-format` fixed the issue

<@Huong> I tried running your code with the following `insertAt (-1) 'b' (Array.fromList [ 'a', 'c' ])` and I can't understand why it returns `[ 'a', 'b', 'c' ]` instead of `[ 'b', 'a', 'c' ]`. I tried it with other negative values and they all return `[ 'b', 'a', 'c' ]`.
2019-03-05T12:22:12.507300
Jae
elmlang
general
I am not Ilias but dare to answer :slightly_smiling_face: This is due to `Array.slice` which treats negative indices as offset from the end of array.
2019-03-05T12:26:49.507500
Lynne
elmlang
general
So `before` becomes `['a']`, `after` becomes `['c']` and after pushing `'b'` it becomes `['a', 'b', 'c']`
2019-03-05T12:28:32.507700
Lynne
elmlang
general
If you want `[ 'b', 'a', 'c' ]`, you'd have to `max 0 idx` or something. The main reason it behaves this way is because `slice` allows (both) indexes to be negative. so say you give it `-1`, you get `before = Array.slice 0 -1 [ 'a', 'c' ] = [ 'a' ]` and `after = Array.slice -1 2 [ 'a', 'c' ] = [ 'c' ]`
2019-03-05T12:28:32.507900
Huong
elmlang

yeah, exactly that
2019-03-05T12:28:42.508100

I am sorry for jumping in :slightly_smiling_face:
2019-03-05T12:29:28.508300
Lynne
elmlang

to put it another way, the `insertAt` I "proposed" should (I think) also work with negative indexes, just wrapping around the end.
