elmlang | general | is it because its hard to guarantee length? | 2019-05-02T04:30:52.386000 | Isaias |
elmlang | general | I’m a developer, first and foremost | 2019-05-02T04:31:09.386100 | Huong |
elmlang | general | Isnt `(,)` still a function? | 2019-05-02T04:31:36.386600 | Isaias |
elmlang | general | a frontend dev | 2019-05-02T04:32:00.386700 | Isaias |
elmlang | general | Nope, the tuple constructors were removed in 0.19 | 2019-05-02T04:32:59.387200 | Huong |
elmlang | general | Eh, backend, too - whatever is required | 2019-05-02T04:33:27.387400 | Huong |
elmlang | general | Will tuples be removed? | 2019-05-02T04:33:31.387700 | Isaias |
elmlang | general | where do you work? what do you think of it? | 2019-05-02T04:34:02.387800 | Isaias |
elmlang | general | I’m actually at work so I don’t really have bandwidth for general small talk, sorry! We can chat about this later, if you’d like :slightly_smiling_face: | 2019-05-02T04:35:12.388000 | Huong |
elmlang | general | sure | 2019-05-02T04:35:26.388400 | Isaias |
elmlang | general | It’s not really a plan right now, but who knows what the future holds :smile: | 2019-05-02T04:35:58.389100 | Huong |
elmlang | general | id be fine with it | 2019-05-02T04:36:09.389300 | Isaias |
elmlang | general | If they were replaced with `Pair` or maybe some slightly mroe convenient syntax | 2019-05-02T04:36:52.390100 | Isaias |
elmlang | general | what's your issue with tuple syntax ? | 2019-05-02T04:37:41.390500 | Syble |
elmlang | general | `Pair a b` is easier to manage than `(a, b)` on a textual level | 2019-05-02T04:38:38.391300 | Isaias |
elmlang | general | also easier to read because you dont have to parse that the parentheses aren't a subexpression | 2019-05-02T04:39:21.392500 | Isaias |
elmlang | general | <@Isaias> actually I found this Tuple replacement package :smile:
<https://package.elm-lang.org/packages/bburdette/toop/latest/> | 2019-05-02T04:40:06.393200 | Nana |
elmlang | general | kind of sounds like what you want | 2019-05-02T04:40:48.393400 | Nana |
elmlang | general | perhaps | 2019-05-02T04:41:43.393700 | Isaias |
elmlang | general | thanks for the tip | 2019-05-02T04:42:00.394100 | Isaias |
elmlang | general | If you reduces tuples to the usage of pairs, it might be sound, but I like to envision the third dimension :monkey_face: | 2019-05-02T04:42:29.394700 | Syble |
elmlang | general | I honestly don't know if Pair 1 2 is clearer than (1, 2) | 2019-05-02T04:43:00.395400 | Syble |
elmlang | general | tuples dont support the fourth dimension atm | 2019-05-02T04:43:01.395500 | Isaias |
elmlang | general | but you can do `(x, (y, z))` | 2019-05-02T04:43:22.396000 | Isaias |
elmlang | general | And also just `Triplet x y z` | 2019-05-02T04:43:48.396400 | Isaias |
elmlang | general | Idk either | 2019-05-02T04:44:02.396600 | Isaias |
elmlang | general | Question: does elm have tail call elim? | 2019-05-02T04:44:45.396900 | Isaias |
elmlang | general | Yes :slightly_smiling_face: | 2019-05-02T04:45:23.397200 | Timika |
elmlang | general | :tada: | 2019-05-02T04:45:56.397400 | Isaias |
elmlang | general | None | 2019-05-02T04:47:04.397500 | Isaias |
elmlang | general | so I have a problem | 2019-05-02T04:49:28.397800 | Isaias |
elmlang | general | So I want to run a bunch of state-dependent computations, but I dont want the dom to constantly rerender because it causes it to crash | 2019-05-02T04:54:37.398700 | Isaias |
elmlang | general | actually... i think i have an idea.. ill repport back how it works | 2019-05-02T04:56:01.399900 | Isaias |
elmlang | general | ok it didnt work | 2019-05-02T04:58:58.400200 | Isaias |
elmlang | general | yeah so essenntially i want a continuously updating model but a `view` function thats only effectively called on animation frame | 2019-05-02T04:59:54.401300 | Isaias |
elmlang | general | i dont really know enough about when elm decides to call view to optimize that | 2019-05-02T05:00:46.402200 | Isaias |
elmlang | general | i dont want to slow my computations to animation frame if i dont have to | 2019-05-02T05:01:27.403300 | Isaias |
elmlang | general | `view` is most of the times called with the next animation frame. | 2019-05-02T05:01:38.403400 | Jin |
elmlang | general | hm.. then maybe its not crashing because of too many dom updates | 2019-05-02T05:02:09.404400 | Isaias |
elmlang | general | A sync render is e.g. done when you handle text inputs. | 2019-05-02T05:02:22.404800 | Jin |
elmlang | general | Maybe you can batch your calculations in one function call? So the model just changes once. | 2019-05-02T05:02:49.405200 | Timika |
elmlang | general | Long running calculations will block your view. | 2019-05-02T05:03:26.405900 | Jin |
elmlang | general | so like i have my model do a random calulation and then emit the next dependent calculation | 2019-05-02T05:04:17.406800 | Isaias |
elmlang | general | so in theory it can essentially reduce to a monad op however i know that in the end the state will still require changing continuously | 2019-05-02T05:05:04.407700 | Isaias |
elmlang | general | so batching more calculations just means more is asked to be done of the elm runtime at once | 2019-05-02T05:05:26.408200 | Isaias |
elmlang | general | You could do some continuation style as explained here <https://discourse.elm-lang.org/t/asynchronous-parsing/3412/3> | 2019-05-02T05:06:52.408800 | Jin |
elmlang | general | I wonder why adoption of elm isnt bigger. Not that i no any figures but it seems the industry is mainly into typescript and React? | 2019-05-02T05:08:20.409700 | Carter |
elmlang | general | (from my POV there should be elm world domination) =D | 2019-05-02T05:08:52.410500 | Carter |
elmlang | general | dunno <@Carter> but i think the world as a whole does move toward improvement but is strongly biased with familiarity | 2019-05-02T05:12:52.411500 | Isaias |
elmlang | general | Its kind of like live rendering an infinitely long file that you continuously parse | 2019-05-02T05:13:30.412200 | Isaias |
elmlang | general | from my point of view, it's mainly WP with jQuery, so imagine how Elm, a FP, would look like to those :smile: | 2019-05-02T05:15:42.413000 | Syble |
elmlang | general | is jquery still used for new projects? | 2019-05-02T05:26:39.413600 | Isaias |
elmlang | general | is it dying | 2019-05-02T05:28:40.413900 | Isaias |
elmlang | general | if it is done by some backend dev.. or if dev have not enough exp..
as main function was `$` (sizle) that now is replaced with `document.querySelector` | 2019-05-02T05:32:02.415600 | Liza |
elmlang | general | honestly I don't know | 2019-05-02T05:32:05.415700 | Syble |
elmlang | general | is it possible to write a `mapN` with lists or does the type system not allow it | 2019-05-02T05:46:41.416800 | Isaias |
elmlang | general | Well, the problem is the target function declaration I guess. AFAIK, there is no variadic functions in Elm | 2019-05-02T05:51:05.416900 | Syble |
elmlang | general | so a type variable cant stand for a function type? | 2019-05-02T05:52:27.417100 | Isaias |
elmlang | general | cant recursive union types work like variadic functions | 2019-05-02T05:58:53.417300 | Isaias |
elmlang | general | It is possible to write a variadic `map`, but, since it has to be type-safe, all lists should have the same type | 2019-05-02T05:59:50.417500 | Lashawna |
elmlang | general | How would you imagine a signature for such a function would look? :thinking_face: | 2019-05-02T06:00:02.417700 | Huong |
elmlang | general | ```
mapN:
(List a -> result)
-> List (List a)
-> List result
``` | 2019-05-02T06:00:41.417900 | Lashawna |
elmlang | general | Yeah, I meant <@Isaias> :smile: | 2019-05-02T06:01:07.418300 | Huong |
elmlang | general | <@Lashawna> that would be `List.map (List.map f)` right? Just so I have the right mental model in mind | 2019-05-02T06:02:01.418500 | Huong |
elmlang | general | seems like that `mapN` function would pretty much just be `List.foldl` | 2019-05-02T06:15:21.418700 | Nana |
elmlang | general | oh, even just `List.map` :smile: | 2019-05-02T06:16:21.418900 | Huong |
elmlang | general | ```
(a -> b) -> List a -> List b
(List a -> b) -> List (List a) -> List b``` | 2019-05-02T06:17:23.419100 | Huong |
elmlang | general | anyway, long story short: if I hear `mapN` in this context, I imagine a function which takes a list of lists, and a function that has the same amount or parameters with corresponding types as the list of lists. It’s definitely not trivial to express that in Elm types, and I have a hunch it might not be possible at all.... | 2019-05-02T06:25:40.419300 | Huong |
elmlang | general | its very cool | 2019-05-02T06:30:50.419500 | Isaias |
elmlang | general | i imagine its related because it has to do with recursive types, I was thinking you might be able to use something like a `Succ` system to determine how many more times a function can be called | 2019-05-02T06:32:19.419700 | Isaias |
elmlang | general | I was thinking about counting with types the other day, and looked for it, but couldn't remember where i saw it before. This is it! | 2019-05-02T06:33:00.419900 | Isaias |
elmlang | general | peano numbers | 2019-05-02T06:33:26.420100 | Huong |
elmlang | general | yeah thats right | 2019-05-02T06:33:34.420300 | Isaias |
elmlang | general | they’re cool stuff, but not super useful in Elm | 2019-05-02T06:33:37.420500 | Huong |
elmlang | general | I think rtfeldman showed me something like it that he wrote | 2019-05-02T06:33:48.420700 | Isaias |
elmlang | general | Yeah, he did a `vector` module with them at some point, I think | 2019-05-02T06:35:16.420900 | Huong |
elmlang | general | "loop/structural invariants that can be enforced at compile time" might make a fun senior thesis | 2019-05-02T06:36:16.421100 | Isaias |
elmlang | general | can i chain cmds? why is there no Cmd.andThen? | 2019-05-02T06:40:08.421600 | Isaias |
elmlang | general | A command is not guaranteed to even lead to a result (ports and navigation are good examples), so chaining them with `andThen` doesn’t really make sense | 2019-05-02T06:42:33.422700 | Huong |
elmlang | general | That’s what tasks are for :slightly_smiling_face: | 2019-05-02T06:42:44.422900 | Huong |
elmlang | general | right... i think i need to better articulate what i want | 2019-05-02T06:45:15.423700 | Isaias |
elmlang | general | Reminded me of this weird job interview question :slightly_smiling_face:
<https://www.reddit.com/r/javascript/comments/9vxdkx/was_asked_this_js_interview_question_is_this_even/> | 2019-05-02T06:50:15.423800 | Lashawna |
elmlang | general | In JS anything is possible though :blush: | 2019-05-02T06:51:18.424100 | Nana |
elmlang | general | For better or worse | 2019-05-02T06:51:59.424300 | Nana |
elmlang | general | Haha, I’m not sure about the “for better” part :smile: | 2019-05-02T06:54:46.424500 | Lashawna |
elmlang | general | say you’ve got a large list of `ul` and `li` and I want to be able to click one of them and, for example, expand it or something. I understand I must use an event from `Html.Events` like `onClick`, but upon sending the message how do I know which one of `li` items was clicked? | 2019-05-02T06:56:47.426400 | Vilma |
elmlang | general | <@Vilma> you include some kind of id value in the produced msg to identify which item was clicked | 2019-05-02T06:58:34.428200 | Earlean |
elmlang | general | pretty sure its possible | 2019-05-02T06:59:01.428700 | Isaias |
elmlang | general | didnt look at solution | 2019-05-02T06:59:08.429000 | Isaias |
elmlang | general | speaking of annything is possible: javascript is a minlang | 2019-05-02T06:59:31.429300 | Isaias |
elmlang | general | <http://www.jsfuck.com/> | 2019-05-02T06:59:48.429600 | Isaias |
elmlang | general | I thought as much, but in my case I’m not really sure how I can accomplish this :thinking_face: | 2019-05-02T07:01:23.430900 | Vilma |
elmlang | general | I guess a CSS id works? | 2019-05-02T07:01:47.431200 | Vilma |
elmlang | general | Are your `li`s generated from a list? | 2019-05-02T07:02:40.431500 | Roberta |
elmlang | general | im curious how can `addSubtract(1)(2)(3)` return `0` but `addSubtract(1)(2)(3)(4)(5)(6)`=`0(4)(5)(6)` return a callback after the `(3)` call | 2019-05-02T07:02:55.431600 | Isaias |
elmlang | general | hmm yeah good point, didn't think about the currying :thinking_face: | 2019-05-02T07:05:29.431800 | Nana |
elmlang | general | doesnt mean its not possible if maybe javascript implicitly casts some value between contexts | 2019-05-02T07:06:58.432000 | Isaias |
elmlang | general | yes | 2019-05-02T07:07:14.432300 | Vilma |
elmlang | general | I’m thinking about using `List.indexedMap` | 2019-05-02T07:07:23.432600 | Vilma |
elmlang | general | one thing you could do is return a function with `.valueOf()` set to the answer | 2019-05-02T07:08:24.432700 | Nana |
