elmlang | general | (need to think if this was a valid statement though) | 2019-05-17T06:41:53.134700 | Lynne |
elmlang | general | if only `type ID = ID String` and such were `comparable` :pray: | 2019-05-17T06:42:04.134900 | Nana |
elmlang | general | Yeah, that’s a good use-case :thumbsup: | 2019-05-17T06:43:04.135100 | Huong |
elmlang | general | If I don’t forget, I’ll add it somewhere this weekend | 2019-05-17T06:43:30.135300 | Huong |
elmlang | general | <@Lynne> I'm already short-circuiting on the first error, I think `Result.andThen` would just be another way of writing it instead of using `case..of` ? | 2019-05-17T06:51:27.135500 | Nana |
elmlang | general | <@Huong> cool :smile: submitted an issue | 2019-05-17T06:52:22.135800 | Nana |
elmlang | general | or actually I'm not short-circuiting, and neither would `Result.andThen` | 2019-05-17T07:00:23.136100 | Nana |
elmlang | general | to do that you'd have to write a recursive function instead of using `List.foldr` | 2019-05-17T07:00:58.136300 | Nana |
elmlang | general | oh btw `decodeString` doesn't work, unless you first wrap the string in `"` | 2019-05-17T07:04:50.136500 | Nana |
elmlang | general | Correct, that’s what I was fighting with… | 2019-05-17T07:06:18.136700 | Lynne |
elmlang | general | (json-extra uses the recursive approach. Pro: it short circuits. Con: it’s not currently tail-recursive, so probably best not to use it on objects with ~6k entries. I plan to take care of that this weekend, too) | 2019-05-17T07:06:27.136900 | Huong |
elmlang | general | That’s what I have come with so far: <https://ellie-app.com/5yQzNPkJFYxa1> | 2019-05-17T07:07:11.137100 | Lynne |
elmlang | general | (Safari sucks btw) | 2019-05-17T07:07:26.137400 | Lynne |
elmlang | general | Dunno if it is better than what <@Nana> suggested | 2019-05-17T07:07:54.137600 | Lynne |
elmlang | general | But as far as I understand it is tail recursive | 2019-05-17T07:08:06.137800 | Lynne |
elmlang | general | yeah, need to reverse the list at the end, though. Technically JS object aren’t ordered, but there is a (fair) expectation that order is preserved nevertheless | 2019-05-17T07:08:19.138000 | Huong |
elmlang | general | Correct | 2019-05-17T07:08:30.138200 | Lynne |
elmlang | general | <https://ellie-app.com/5yQCyPfyFC4a1> | 2019-05-17T07:09:12.138400 | Lynne |
elmlang | general | yep, exactly | 2019-05-17T07:09:53.138600 | Huong |
elmlang | general | The hardest thing is finding a name :sweat_smile: | 2019-05-17T07:10:10.138800 | Huong |
elmlang | general | Yeah… | 2019-05-17T07:10:50.139000 | Lynne |
elmlang | general | since you have `dict2` which is the equivalent for `Decode.dict` I guess you could call it `keyValuePairs2` ? | 2019-05-17T07:11:48.139200 | Nana |
elmlang | general | Yeah, that would be my first idea, too. It seems like pretty bad naming, though, but then I also don’t want to do a breaking change.
Urgh, naming. | 2019-05-17T07:13:08.139400 | Huong |
elmlang | general | Something like `typedKeyValuePairs` or `keyValuePairsTyped` maybe? | 2019-05-17T07:16:20.139600 | Lynne |
elmlang | general | customKeyValuePairs? | 2019-05-17T08:27:08.139900 | Raylene |
elmlang | general | <@Nana> forgive me, i just opened slack and i could only think about this: <https://imgur.com/a/JHKOHEn> | 2019-05-17T10:21:50.141600 | Lilli |
elmlang | general | Does anyone know the depth of `lazy1`? | 2019-05-17T13:00:38.143400 | Willodean |
elmlang | general | what is the map size? | 2019-05-17T13:00:51.143700 | Willodean |
elmlang | general | <@Willodean> it doesn't really have a depth, it memoizes a function with one argument | 2019-05-17T13:25:06.145000 | Augustus |
elmlang | general | The code bit for it is here <https://github.com/elm/virtual-dom/blob/dev/src/Elm/Kernel/VirtualDom.js#L685> | 2019-05-17T13:25:59.145900 | Augustus |
elmlang | general | <@Augustus> by depth I mean what is the cache size? | 2019-05-17T13:26:08.146100 | Willodean |
elmlang | general | It isn't stored in a cache like you are thinking of | 2019-05-17T13:27:00.146900 | Augustus |
elmlang | general | Check out that code in virtual DOM, there is is comparing the old and new arguments to see if they are referentially equal, if they are all equal it will lazy render | 2019-05-17T13:28:14.148200 | Augustus |
elmlang | general | so the depth is 1 | 2019-05-17T13:41:21.148900 | Willodean |
elmlang | general | as in it stores the last value only | 2019-05-17T13:41:32.149200 | Willodean |
elmlang | general | The old arguements is the cache | 2019-05-17T13:42:05.149600 | Willodean |
elmlang | general | Sorry I thought you were talking depth like keeping a cache for the arguments to view functions for child nodes of lazy nodes | 2019-05-17T13:46:27.151300 | Augustus |
elmlang | general | right, which it does <@Augustus> | 2019-05-17T14:26:36.151600 | Willodean |
elmlang | general | Thanks! I have been playing a bit with lazy and keyed and they didn't seem to make any difference. After poking a bit, it seems that it's specifically how the _menu_ plugin manipulates the DOM to insert the menu. I'll try web components first, and if not I'll probably modify the menu plugin to expect that the needed HT... | 2019-05-17T14:34:41.152000 | Kira |
elmlang | general | nah it only does for the top level, if any of the arguments has changed it re-renders it all | 2019-05-17T14:41:11.153300 | Alicia |
elmlang | general | forgot I switched accounts, antew is me too, this is my work account :slightly_smiling_face: | 2019-05-17T14:41:31.153800 | Alicia |
elmlang | general | like say you have a function
```
renderSomething: Int -> Int -> Html msg
renderSomething val1 val2 =
div [] [
div [] [ text <| String.fromInt val1 ]
, div [] [ text <| String.fromInt val2 ]
]
```
With some extra work it could be able to see that if only `val1` changes or only `val2` chan... | 2019-05-17T14:43:24.155700 | Alicia |
elmlang | general | I keep forgetting this :sweat_smile: | 2019-05-17T16:36:44.156000 | Huong |
elmlang | general | I need to just delete this one and go on antew only :cry: | 2019-05-17T16:44:11.156200 | Alicia |
elmlang | general | Hi. I am trying to create a fuzzer of type Fuzzer (List Int) that would contain exactly 10 random integer values ranging from 0 to 10. Has anyone ever came up with something similar? Thanks. | 2019-05-17T18:00:15.158400 | Shin |
elmlang | general | yea, you'd need this function
```
combine : List (Fuzzer a) -> Fuzzer (List a)
combine l =
case l of
[] -> Fuzz.constant []
x :: xs -> Fuzz.map2 (::) x (combine xs)
``` | 2019-05-17T18:16:20.158900 | Virgie |
elmlang | general | then I think `combine (List.repeat 10 (Fuzz.intRange 0 10))` should do it | 2019-05-17T18:16:44.159400 | Virgie |
elmlang | general | Thanks <@Virgie> for the quick reply. | 2019-05-17T18:18:37.159800 | Shin |
elmlang | general | a more efficient version (for general use, 10 element lists are fine) is
```
combine : List (Fuzzer a) -> Fuzzer (List a)
combine list = combineHelp list (Fuzz.constant [])
combineHelp rest accum =
case rest of
[] ->
accum
x :: xs ->
combineHelp rest (Fuzz.map2 ... | 2019-05-17T18:19:15.160300 | Virgie |
elmlang | general | So... `traverse` :stuck_out_tongue_closed_eyes: | 2019-05-17T19:00:36.160800 | Raylene |
elmlang | general | Hi, I'm new. Guide me | 2019-05-17T19:22:10.161300 | Isiah |
elmlang | general | <@Isiah> <https://guide.elm-lang.org/> | 2019-05-17T19:22:51.161500 | Nana |
elmlang | general | Thanks <@Nana> | 2019-05-17T19:23:38.161900 | Isiah |
elmlang | general | Am I missing something or there isn’t a direct way to generate a `List` of values with a “step” parameter? Something like `List.range start end step` ? I guess I have to use range and then multiply the value, right? `0 1 2 3` * step | 2019-05-18T05:56:01.164600 | Hoa |
elmlang | general | Doesn't look like there's a `List.range` with step, not even in `elm-community/List.Extra` | 2019-05-18T06:06:00.164800 | Jae |
elmlang | general | Yeah, I checked there too. | 2019-05-18T06:09:04.165100 | Hoa |
elmlang | general | Sounds like a chance to implement it and make a pull request | 2019-05-18T06:09:58.165300 | Jae |
elmlang | general | is there a common way to embed videos from multiple sources (yt and vimeo)? I would like to use something like <https://plyr.io> | 2019-05-18T06:13:21.166100 | Allison |
elmlang | general | You could wrap that in a web component | 2019-05-18T06:13:44.166500 | Danika |
elmlang | general | :thinking_face: the plyr player? | 2019-05-18T06:14:15.166900 | Allison |
elmlang | general | Yeah, just wrap it if it works for you | 2019-05-18T06:25:45.167400 | Raylene |
elmlang | general | How it will work with elm’s runtime if the js code changes the component? What I mean is — I thought I cannot let js modify the DOM because it will break elm’s virtual DOM (similarly to how adblockers breaks elm code).. | 2019-05-18T06:30:02.169600 | Allison |
elmlang | general | thats what web components are for, you create the web component in elm, and that components js handles its own "sub" dom | 2019-05-18T06:31:30.170100 | Danika |
elmlang | general | awesome! haven’t heard of it before! every day you learn something new I guess.. thanks! | 2019-05-18T06:33:11.170800 | Allison |
elmlang | general | Hi, how can I parse URL query parameters into a list of key value pairs? I’m able to parse them, if I know what they are, but not if they can be anything. E.g.
I want to parse this URL:
```host:80/path?a=1&b=2&foo=bar```
into:
```
[("a", "1"), ("b", "2"), ("foo", "bar")]
``` | 2019-05-18T08:30:30.174100 | Tarah |
elmlang | general | One crude way would be to just take that string after `?` and split by `&`. This way you are able to handle any number of params | 2019-05-18T08:45:47.175400 | Hoa |
elmlang | general | It’s more fragile, of course | 2019-05-18T08:46:03.175700 | Hoa |
elmlang | general | Ok, I'll do that, until I find a better way. Thx | 2019-05-18T09:29:26.176400 | Tarah |
elmlang | general | You might be able to use <https://package.elm-lang.org/packages/elm/url/latest/Url-Parser-Query> | 2019-05-18T10:48:07.176600 | Su |
elmlang | general | This is exactly what my problem is. I cannot come up with a way to achieve this with that API. | 2019-05-18T10:57:21.176700 | Tarah |
elmlang | general | Sorry about that, I didn’t read your question carefully enough…I understand your problem now. This sounds like a task that is big, but you could write your own parser with <https://package.elm-lang.org/packages/elm/parser/latest/>. There is an elm-conf talk about parsers; it’s featured in the latest issue of elm weekly... | 2019-05-18T11:56:03.177000 | Su |
elmlang | general | Hi, Was your talk recorded? Could I watch it? | 2019-05-18T12:33:40.177300 | Giselle |
elmlang | general | Hi all, does anyone have an example of killing Process.sleep tasks before they resolve? I'm having a hard time making sense of the process module and what to do with it | 2019-05-18T13:15:41.179000 | Bebe |
elmlang | general | Basically I want to cancel a timeout once something has happened to avoid undesired messages coming in | 2019-05-18T13:16:12.179500 | Bebe |
elmlang | general | what do you have so far? | 2019-05-18T13:18:06.180600 | Virgie |
elmlang | general | Do I have to Task.perform both the Process.sleep and the Process.spawn sleepTask and make a message to get the Id of the timeout? | 2019-05-18T13:18:26.181100 | Bebe |
elmlang | general | not much, I've been trying to figure out what code to write to be honest :sweat_smile: | 2019-05-18T13:18:59.181600 | Bebe |
elmlang | general | yea, I think you need to first perform the spawning (so you have an ID), store that in the model, then kill when needed | 2019-05-18T13:20:25.182500 | Virgie |
elmlang | general | ```
abandonTimeout : Msg -> Cmd Msg
abandonTimeout msg =
let
sleepTask =
Process.sleep 300
timer =
Process.spawn sleepTask
in
Cmd.batch
[ Task.perform (\() -> msg) sleepTask
, Task.perform (\id -> TimeoutId id) timer
]
```
this seems ... | 2019-05-18T13:21:59.183400 | Bebe |
elmlang | general | I wonder if I'm spawning the sleep task twice with what I'm doing | 2019-05-18T13:26:23.184900 | Bebe |
elmlang | general | :confused: so confused | 2019-05-18T13:26:27.185100 | Bebe |
elmlang | general | I think you are | 2019-05-18T13:26:32.185300 | Virgie |
elmlang | general | so what do you want this to do? | 2019-05-18T13:26:42.185500 | Virgie |
elmlang | general | i want to get a `Msg` after 300 ms to do some logic. I want to cancel that Task if something else happens before the 300ms so that that `Msg` never arrives | 2019-05-18T13:27:44.186700 | Bebe |
elmlang | general | sounds ridiculous, but I'm dealing with mouse enter and leave interactions which actually have that kind of timely interactions | 2019-05-18T13:28:15.187400 | Bebe |
elmlang | general | gonna try on an ellie | 2019-05-18T13:28:49.187800 | Bebe |
elmlang | general | that thing I wrote is definitely not working. I'm still getting the timeout message even if I kill the pid, so I must be killing the duplicate sleep task | 2019-05-18T13:46:28.188600 | Bebe |
elmlang | general | here is the example: <https://ellie-app.com/5zqtzfQMRZxa1> clicking trigger timeout and cancelling it before two seconds, look at the logs (bottom up) and the TimedOut message is still received | 2019-05-18T13:49:00.189300 | Bebe |
elmlang | general | I'm not sure what to do, seems like a simple enough use case, but I can't figure out Process, and I'm not having much luck with google | 2019-05-18T13:58:53.190500 | Bebe |
elmlang | general | <https://ellie-app.com/5zqF55LKc92a1> | 2019-05-18T14:00:02.190700 | Lynne |
elmlang | general | Seems like it works now | 2019-05-18T14:00:12.191000 | Lynne |
elmlang | general | WOT | 2019-05-18T14:01:30.191300 | Bebe |
elmlang | general | Apparently you created two processes | 2019-05-18T14:02:14.191600 | Lynne |
elmlang | general | yeah, I had no idea what I was doing lol | 2019-05-18T14:02:31.192200 | Bebe |
elmlang | general | One was killed (presumably), another one completed | 2019-05-18T14:02:32.192400 | Lynne |
elmlang | general | I see now, you are using Task.succeed to trigger a message. That's the missing piece I wasn't thinking aoubt | 2019-05-18T14:02:51.193400 | Bebe |
elmlang | general | Thanks a lot Sergey | 2019-05-18T14:03:42.193900 | Bebe |
elmlang | general | ur welcome | 2019-05-18T14:03:47.194100 | Lynne |
elmlang | general | It may need a bit of polishing (like removal of `()` from arguments) but I leave it in your hands | 2019-05-18T14:04:32.194700 | Lynne |
elmlang | general | right on! | 2019-05-18T14:04:43.194900 | Bebe |
