elmlang | general | If you write a DOT -> gp2 and a gp2 -> DOT converter. This would make it for you possible to use Kite as well as other graph drawing software. | 2019-02-20T11:33:23.003700 | Reuben |
elmlang | general | I have put “DOT file import/export” to the top of my to do list for Kite: <https://github.com/erkal/kite/projects/1#card-17893413> But if you want to write parsers in elm, than you could do it, too. Because I will probably not have time for doing this for a while. | 2019-02-20T11:36:41.003900 | Reuben |
elmlang | general | <@Krista> Thank you, that's great to hear. | 2019-02-20T14:25:59.004700 | Sari |
elmlang | general | For anyone curious, the post in question is <https://korban.net/posts/elm/2019-02-15-combining-http-requests-with-task-in-elm/> and it is indeed very good! | 2019-02-20T14:36:10.005400 | Janiece |
elmlang | general | And <@Sari> I'm glad to see from your future post about `elm-ui` in November 2019 that we will still be able to "Forget CSS and enjoy creating UIs in pure Elm" several months from now :stuck_out_tongue: | 2019-02-20T14:38:27.006700 | Janiece |
elmlang | general | Whats is the quote of evancz related to docs ? | 2019-02-20T14:58:18.007800 | Alyce |
elmlang | general | "It's not done until the docs are great"? <https://twitter.com/czaplic/status/928359227541798912?s=19> | 2019-02-20T15:22:54.008500 | Janiece |
elmlang | general | With the help of <@Lizabeth> and <@Dede> I see the way to make inbound JS ports that have no payload (nullary functions or functions without arguments) is `port signedOut : (() -> msg) -> Sub msg` along with a subscription of `signedOut (always SignedOut)`.
What is the expected way we should use outbound nullary functions? Is it `port signOut : () -> Cmd msg` and in the `update` function: `( model, signOut () )`? | 2019-02-20T20:08:05.012700 | Jacquelyn |
elmlang | general | <@Jacquelyn> yep, but it's generally an anti-pattern to not send a value on your port | 2019-02-20T20:20:31.013400 | Earlean |
elmlang | general | It's recommended to have 1 outgoing and 1 incoming port for each 'process' (aka. actor) you're communicating with. You shouldn't try to have one port for each JS function you want to call | 2019-02-20T20:22:36.014900 | Earlean |
elmlang | general | I see, thank you for the recommendation | 2019-02-20T20:29:42.015900 | Jacquelyn |
elmlang | general | <https://youtu.be/P3pL85n9_5s> is a great talk about ports | 2019-02-20T20:31:00.016100 | Earlean |
elmlang | general | Hey y’all, is there a good “get help” channel? In the last day or so we’ve started seeing some crashes in compiled elm code, in recursive calls to `eqHelp`. I know we do some funny stuff so it’s probably mostly an us problem but some guidance on how to track it down would be super helpful! | 2019-02-20T23:06:40.017600 | Tonda |
elmlang | general | i'd start with debug.log statements around suspected recursions, this channel's got the most eyes | 2019-02-20T23:12:46.018500 | Ruthann |
elmlang | general | There's <#C0K8VHA6B|help>, though with less :eyes: than here | 2019-02-20T23:43:02.019400 | Lizabeth |
elmlang | general | Anyone else getting the following error in the console when hitting and it not progressing past the loading screen?
<https://ellie-app.com/new>
```
Unchecked runtime.lastError: The message port closed before a response was received.
``` | 2019-02-21T03:00:47.021800 | Lizabeth |
elmlang | general | I believe that error message is caused by a browser extension <https://github.com/mozilla/webextension-polyfill/issues/130> | 2019-02-21T03:05:23.022300 | Augustus |
elmlang | general | Thanks it was uBlock Origin in my case, which happened to be the only extension that I had running incognito & firefox as well. | 2019-02-21T03:07:14.023200 | Lizabeth |
elmlang | general | do you know it was blocking by chance? I have ublock as well but it loads for me | 2019-02-21T03:07:52.023800 | Augustus |
elmlang | general | hi everyone, where should json decoders go when creating custom types that you don't want to expose outside the module? I end up always creating cycles with this... | 2019-02-21T09:25:38.026400 | Nancy |
elmlang | general | Just keep them in the module where you define the custom type. You can’t keep the type opaque otherwise.
It’s in general a good idea to keep types and functions using those types close together. | 2019-02-21T09:29:18.028000 | Jin |
elmlang | general | and I guess other methods like view functions should go on the same module, right? | 2019-02-21T09:31:28.028700 | Nancy |
elmlang | general | Yes. But you can of course factor out general view helpers. A relevant talk is <https://www.youtube.com/watch?v=XpDsk374LDE> | 2019-02-21T09:33:01.029500 | Jin |
elmlang | general | but to write the view function you need to be able to case on the custom type internals | 2019-02-21T09:34:05.030000 | Nancy |
elmlang | general | Sure, functions using the custom type should live there. With general view helpers I meant something like layout wrapper, views that take some Html and wrap it in some other Html. | 2019-02-21T09:38:14.031800 | Jin |
elmlang | general | right | 2019-02-21T09:38:35.032000 | Nancy |
elmlang | general | As it's been mentioned below there is a <#C0K8VHA6B|help> channel. Also, this is probably what you are after:

elmlang | general | They seem to come in one-by-one now. :slightly_smiling_face: :tada: | 2019-02-21T10:13:48.033100 | Timika |
elmlang | general | There are advantages to this:
1) you can release as their finished instead of holding the up until done.
2) as long as you don’t spread it out too much, you can keep people’s attention for a longer period of time. | 2019-02-21T10:41:03.035200 | Cammy |
elmlang | general | thanks! Yes we’re seeing a crash in this code | 2019-02-21T10:53:39.035600 | Tonda |
elmlang | general | We're publishing as fast as we can :slightly_smiling_face: <@Ashleigh> and <@Moon> is hard at work uploading. | 2019-02-21T11:28:43.036200 | Waylon |
elmlang | general | :tada: Can’t wait to watch robin’s talk | 2019-02-21T11:29:55.036500 | Timika |
elmlang | general | Agreed. Glad Luca’s is up already too. | 2019-02-21T11:34:43.037100 | Cammy |
elmlang | general | Hey folks. I'm staring at a problem in Elm where there seems to exist no great way to integrate gRPC. There are indeed no libraries that solve the problem, although there are two protocol buffer libraries that could be leveraged to help.
My problem is that grpc-web (the protocol that we'd need to implement) is obviously low level javascript-y http/2 type stuff. The definition of kernel code. Is there some process by which I can begin developing a module that's intended to fit into the kernel of Elm? And would it ever be accepted? Is there any process for this? | 2019-02-21T13:36:06.043100 | Rosaria |
elmlang | general | almost done now! | 2019-02-21T13:39:50.043800 | Moon |
elmlang | general | <@Rosaria> I think Evan mentioned somewhere that he prefers seeing posts at discourse/Reddit where the needs are stated and some feedback is gathered. It could be a good place to start and see if there are people who are interested in having Elm gRPC implementation as well. | 2019-02-21T14:21:07.045600 | Lynne |
elmlang | general | Have you considered a port that wraps anything you can’t do in Elm due to browser apis? | 2019-02-21T14:22:05.046600 | Agustin |
elmlang | general | You have access to some http request stuff, but maybe make a http 2 equivalent? | 2019-02-21T14:22:33.047400 | Agustin |
elmlang | general | The comment about browser APIs is a limiting factor to implement gRPC in pure javascript and doesn't really concern elm fwiw. Port or no port you still can't do it. | 2019-02-21T14:22:38.047600 | Rosaria |
elmlang | general | Hence grpc-web protocol is a stop-gap to enable clients to talk "a form" of grpc | 2019-02-21T14:22:55.048000 | Rosaria |
elmlang | general | If you can do it in JS you can do it in ports. | 2019-02-21T14:23:16.048700 | Agustin |
elmlang | general | Being that it's not possible to implement grpc in pure javascript, the proposal would target grpc-web instead. | 2019-02-21T14:23:19.048800 | Rosaria |
elmlang | general | Yes, you're getting confused with what that statement meant. I'm trying to clarify. | 2019-02-21T14:23:42.049100 | Rosaria |
elmlang | general | :slightly_smiling_face: | 2019-02-21T14:23:43.049300 | Rosaria |
elmlang | general | It's an important distinction that there are two protocols, and one is impossible in pure JS and hence impossible with a port. | 2019-02-21T14:24:12.049900 | Rosaria |
elmlang | general | And that we'd be targetting the one that IS possible in pure JS & ports. :slightly_smiling_face: | 2019-02-21T14:24:21.050200 | Rosaria |
elmlang | general | <@Agustin> Also fwiw the purpose of grpc is to have low latency and performant serialization. Using a port forces me to serialize to json, which then gets converted into an object in JS land, which then is serialized to binary. Not very efficient :confused: | 2019-02-21T14:26:10.051800 | Rosaria |
elmlang | general | If its impossible in pure js without a port it’s impossible in elm | 2019-02-21T14:27:56.052500 | Agustin |
elmlang | general | I literally said that. | 2019-02-21T14:28:04.052800 | Rosaria |
elmlang | general | I'm not arguing. | 2019-02-21T14:28:06.053000 | Rosaria |
elmlang | general | lol. | 2019-02-21T14:28:07.053200 | Rosaria |
elmlang | general | Ok cool, going back to your original statement I think Elm isn’t the right choice for you. | 2019-02-21T14:28:47.053700 | Agustin |
elmlang | general | There is no way to do what you want. | 2019-02-21T14:28:53.054000 | Agustin |
elmlang | general | Short of Evan blessing you with an exploration repo. You can’t do it. | 2019-02-21T14:29:15.054400 | Agustin |
elmlang | general | And there are very little active exploration repos | 2019-02-21T14:29:36.054800 | Agustin |
elmlang | general | Not even WebGl has made it to core, and websockets got left behind in 0.18 | 2019-02-21T14:29:56.055300 | Agustin |
elmlang | general | Websockets being left behind is a little concerning. | 2019-02-21T14:30:40.055900 | Rosaria |
elmlang | general | But it sounds like this is simply a people problem. Perhaps it can be solved with discussion like Sergey mentions. | 2019-02-21T14:31:02.056400 | Rosaria |
elmlang | general | Also - I'm already fairly invested in Elm. | 2019-02-21T14:31:17.056600 | Rosaria |
elmlang | general | This is a change we want to make on the backend. | 2019-02-21T14:31:25.056900 | Rosaria |
elmlang | general | So Elm either comes along for the ride or we'll have to abandon the idea and try something strictly worse. Like REST/JSONAPI/Swagger. | 2019-02-21T14:31:45.057400 | Rosaria |
elmlang | general | GraphQL | 2019-02-21T14:32:00.057800 | Agustin |
elmlang | general | There are beautiful GraphQL libraries in Elm, run on standard protocols | 2019-02-21T14:32:14.058400 | Agustin |
elmlang | general | Standard protocols are the strictly worse part. | 2019-02-21T14:32:21.058700 | Rosaria |
elmlang | general | The beauty of GraphQL is its not wedded to them | 2019-02-21T14:32:36.059100 | Agustin |
elmlang | general | It runs on them but when HTTP/2 HTTP/3 is ready it’ll run on them too | 2019-02-21T14:32:53.059500 | Agustin |
elmlang | general | HTTP/2 is ready and I'd be concerned if it didn't run on them :confused: | 2019-02-21T14:33:06.059800 | Rosaria |
elmlang | general | Not all webservers etc… | 2019-02-21T14:33:33.060500 | Agustin |
elmlang | general | etc. | 2019-02-21T14:33:37.060600 | Rosaria |
elmlang | general | Does GraphQL solve the problem of describing an APIs methods/serialization? | 2019-02-21T14:34:09.061300 | Rosaria |
elmlang | general | I know precious little about it. | 2019-02-21T14:34:22.061600 | Rosaria |
elmlang | general | But that's the root of the problem we're trying to solve. | 2019-02-21T14:34:28.061900 | Rosaria |
elmlang | general | You describe a schema of what is available | 2019-02-21T14:34:30.062200 | Agustin |
elmlang | general | You write queries / mutations / subscriptions to pull / change / stream that data | 2019-02-21T14:34:50.062700 | Agustin |
elmlang | general | You specify what the api supports, and what your client needs | 2019-02-21T14:35:02.063100 | Agustin |
elmlang | general | Serialisation is standardised based on the schema | 2019-02-21T14:35:19.063500 | Agustin |
elmlang | general | docs for fields / objects are returned via introspection | 2019-02-21T14:35:37.064000 | Agustin |
elmlang | general | I'll look into it. Maybe it's another solution to the problem. | 2019-02-21T14:36:15.064800 | Rosaria |
elmlang | general | Though it still seems like it'll have the same old performance as a random rest API. One of the reasons for choosing gRPC was specifically that. | 2019-02-21T14:37:20.066200 | Rosaria |
elmlang | general | Will have to evaluate. Thanks for your input. | 2019-02-21T14:37:26.066700 | Rosaria |
elmlang | general | It runs over any protocol | 2019-02-21T14:37:40.067100 | Agustin |
elmlang | general | So its common to use websockets etc to improve the push -> pull time | 2019-02-21T14:37:57.067700 | Agustin |
elmlang | general | But those were abandoned in Elm 0.18 :disappointed: | 2019-02-21T14:38:07.068000 | Rosaria |
elmlang | general | No because its trivial to use ports for them | 2019-02-21T14:38:27.068400 | Agustin |
elmlang | general | (Theres no deserialisation overhead, as its sent straight to the websocket) | 2019-02-21T14:38:47.069300 | Agustin |
elmlang | general | but yes websockets use json, and not some binary format | 2019-02-21T14:39:19.070200 | Agustin |
elmlang | general | How is that possible? If it goes through the port it must be serialized somehow no? | 2019-02-21T14:39:22.070300 | Rosaria |
elmlang | general | sure | 2019-02-21T14:39:28.070500 | Agustin |
elmlang | general | it just does it before the port | 2019-02-21T14:39:37.071100 | Agustin |
elmlang | general | rather than after | 2019-02-21T14:39:40.071400 | Agustin |
elmlang | general | its going to be serialised if you send it over a websocket | 2019-02-21T14:39:50.071900 | Agustin |
elmlang | general | :slightly_smiling_face: | 2019-02-21T14:39:51.072100 | Agustin |
elmlang | general | So the json object the port is carrying is just a string then? | 2019-02-21T14:39:51.072200 | Rosaria |
elmlang | general | And de/serialiaztion happens on the elm side? | 2019-02-21T14:40:21.072700 | Rosaria |
elmlang | general | Totally | 2019-02-21T14:40:31.072900 | Agustin |
elmlang | general | I send some pretty hefty data that way | 2019-02-21T14:40:42.073200 | Agustin |
elmlang | general | (basicall graphql’d equivalent of 100mb csvs) | 2019-02-21T14:40:58.073900 | Agustin |
elmlang | general | The bottleneck is not my ports I can assure you | 2019-02-21T14:41:07.074200 | Agustin |
elmlang | general | (it may help my data is streamed) | 2019-02-21T14:41:33.074900 | Agustin |
