elmlang | general | 0.19 seems like the perfect time to get into Elm though, with the huge compile time improvements! | 2019-03-13T17:21:29.034100 | Nana |
elmlang | general | I started with 0.19, and I'm enjoying it quite a bit at least. Though I'm pretty sure my SPA could use some structural improvement hehe. | 2019-03-13T17:22:12.034700 | Rochell |
elmlang | general | But I'm learning! | 2019-03-13T17:22:15.034900 | Rochell |
elmlang | general | Anyone played around with elm and gojs? Or maybe just canvas? | 2019-03-13T17:22:41.035200 | Kellee |
elmlang | general | <@Kellee> for custom visualizations I would go with elm/svg or elm-visualizations rather than canvas. Shouldn't be a problem to interop with GoJS via ports | 2019-03-13T17:38:50.036600 | Nana |
elmlang | general | <@Leoma>, whatever the mean, what is great also is how you got a WYSIWYG editor. Did you use an hidden input or a content editable? | 2019-03-13T19:43:06.037500 | Velia |
elmlang | general | This is really cool :grinning: | 2019-03-13T19:51:57.037700 | Velia |
elmlang | general | @translate | 2019-03-13T21:37:10.038200 | Latina |
elmlang | general | Is anyone here familiar with `elm-ui`? How do I combine `Element.below` and `Element.onRight` to get something to display to the bottom right of another element? | 2019-03-14T02:46:04.039200 | Deane |
elmlang | general | <@Deane> If you don't get answers here, try the <#C4F9NBLR1|elm-ui> channel :slightly_smiling_face: | 2019-03-14T03:00:59.039600 | Chaya |
elmlang | general | oh ok, thanks! | 2019-03-14T03:04:15.039800 | Deane |
elmlang | general | Hello! I need my app to handle URL queries, but I don't care about the path (I don't know where it will be deployed, so the URL path can be very different). Is there a way to use Url.Query.Parser while ignoring the path? | 2019-03-14T04:05:35.041500 | Dorsey |
elmlang | general | Unrelated: huge, enthusiastic shout out to <@Virgie> for helping us at the workshop last friday. You are awesome! | 2019-03-14T04:07:21.042700 | Dorsey |
elmlang | general | <@Dorsey> No you can’t unfortunately | 2019-03-14T04:09:54.043500 | Lea |
elmlang | general | That what I thought :disappointed: | 2019-03-14T04:10:09.043800 | Dorsey |
elmlang | general | <https://github.com/elm/url/issues/9> | 2019-03-14T04:10:14.044100 | Lea |
elmlang | general | It’s not the first time it’s requested, another issue might be useful to show some interest in this :slightly_smiling_face: | 2019-03-14T04:12:15.045100 | Lea |
elmlang | general | Yeah, for that I have a hack that gets up to 10 segmnts of a path in a `List String`. It goes like this: ```
variadic last =
10
|> List.range 1
|> List.foldl
(\_ parser_ ->
Parser.oneOf
[ parser_
, Parser.map
(\parent child ->
case child of
Content path ->
Content (parent :: path)
_ ->
NotFound
)
(Parser.string </> parser_)
]
)
last
``` | 2019-03-14T04:16:24.046900 | Dorsey |
elmlang | general | But in my current case I simply don't care about the path, so I was hoping I don't have to employ this spaghetti. | 2019-03-14T04:17:15.047700 | Dorsey |
elmlang | general | If you really just don't care about the path at all, just set it to `"/"` in the `Url` you pass to the parser | 2019-03-14T04:19:25.048600 | Huong |
elmlang | general | Haha, yeah! That's so obvious once you said it :face_palm: | 2019-03-14T04:26:54.049500 | Dorsey |
elmlang | general | Good one! | 2019-03-14T04:50:01.050400 | Lea |
elmlang | general | thanks so much! it was a lot of fun to talk to everyone | 2019-03-14T05:11:05.050500 | Virgie |
elmlang | general | Anyone know if there's a spec of whitepaper or something for Elm? Feels like I've seen one before, but can't find it. Going to write a tech spec for another project, but want some inspo | 2019-03-14T07:33:57.051900 | Janna |
elmlang | general | Glad to hear that. We will schedule the first monthly meeting soon. I'll keep you posted. | 2019-03-14T07:34:14.052000 | Dorsey |
elmlang | general | Are you looking for Evan’s thesis? (<https://www.seas.harvard.edu/sites/default/files/files/archived/Czaplicki.pdf>) | 2019-03-14T08:10:08.052500 | Timika |
elmlang | general | has anyone tried to update a pages metadata? any tips on best practices?
javascript only solution?
ports? | 2019-03-14T08:27:05.053300 | Selene |
elmlang | general | We’ve used ports | 2019-03-14T08:27:47.053700 | Simon |
elmlang | general | I have used ports as well:
<https://github.com/olpeh/onkometrorikki/blob/8401b813e0e662e8e78435abb8dc1eb1be364cb2/src/index.js#L44-L77> | 2019-03-14T08:45:03.053900 | Shena |
elmlang | general | Thanks <@Florencia> for the help a couple of weeks ago with the animated numbers. I ended up tweaking your solution a tiny bit but thank you for giving me a great starting point. :raised_hands: | 2019-03-14T09:45:29.054300 | Dorthey |
elmlang | general | invite @translate | 2019-03-14T10:13:49.055300 | Latina |
elmlang | general | @translate | 2019-03-14T10:13:57.055600 | Latina |
elmlang | general | Can you share your solution? :smile: | 2019-03-14T10:22:54.056400 | Kris |
elmlang | general | <@Dorthey> Exciting, and looking slick! | 2019-03-14T10:44:14.057200 | Florencia |
elmlang | general | What is the status of sending Union types through ports? This issue was closed in favor of an issue moved to `elm-plans` but `elm-plans` is now deprecated, so it looks like this issue is no longer under discussion. <https://github.com/elm/compiler/issues/490>
<https://github.com/elm-lang/elm-plans/issues> | 2019-03-14T12:06:13.063100 | Russel |
elmlang | general | You can always push a `Value` though ports, encoding your types exactly as you want them to be encoded. IIRC, you cannot use non-primitives in ports in 0.19. | 2019-03-14T12:13:16.063600 | Timika |
elmlang | general | Oh really? I think in guide it is mentioned that records are still supported | 2019-03-14T12:14:16.063900 | Lynne |
elmlang | general | I cannot find a `Cmd` constructor: | 2019-03-14T12:14:17.064100 | Wendy |
elmlang | general | how do i call first update after init? | 2019-03-14T12:14:37.064200 | Wendy |
elmlang | general | :point_up: That can very well be. Good catch. | 2019-03-14T12:14:42.064300 | Timika |
elmlang | general | I think I understand that point. So, maybe my architecture is non-idiomatic. Is it crazy to try to store an entire model in localStorage if I don’t want to reimplement Encode and Decode for the entire tree? Or maybe I’m making that a bigger deal than it has to be. | 2019-03-14T12:15:16.064600 | Russel |
elmlang | general | It might be not crazy at all, depending on your requirements, but imagine that data in local storage got somehow corrupted. Having your own decoder you will manage it much better than Elm would | 2019-03-14T12:16:50.064800 | Lynne |
elmlang | general | I mentioned this in <#C192T0Q1E|beginners>,
In the answer credited here, it looks like in order to support JE/JD after adding 1 union type in their model type, they need to reimplement the entire record JD/JE <https://stackoverflow.com/questions/37999504/how-to-pass-union-types-through-elm-ports> | 2019-03-14T12:17:19.065000 | Russel |
elmlang | general | In this case, they are looking at storing their model in localStorage through ports | 2019-03-14T12:17:42.065300 | Russel |
elmlang | general | That's correct, here is the list of what is supported out of the box: <https://guide.elm-lang.org/interop/flags.html#verifying-flags> | 2019-03-14T12:17:49.065500 | Lynne |
elmlang | general | For flags I think the consensus that `Value` is preferred for the reasons Sergey stated. | 2019-03-14T12:17:57.065700 | Timika |
elmlang | general | It might be a huge undertaking to write encoders and decoders for you whole model, but with that you have the certainty that if your model somehow changes you have a way to provide backwards compat with old local storage versions of your model for example. | 2019-03-14T12:19:49.066100 | Timika |
elmlang | general | Personally, I don’t want to worry renaming fields and stuff because it might break some public JSON API (like in your case) | 2019-03-14T12:20:38.066400 | Timika |
elmlang | general | What I am saying: It requires some manual effort but you also gain something. :slightly_smiling_face: | 2019-03-14T12:21:28.066600 | Timika |
elmlang | general | This sounds like an X Y problem, what are you trying to achieve with this? (If you really want to do this, you can simply call update within init, its a function like any other.) | 2019-03-14T12:23:20.067800 | Timika |
elmlang | general | It sounds like it would be easier to reason about if I did not try to put a part of my model into local storage, and simply have my own `PersistentState` type which could be a record of `Maybe`s that I send over the ports for local storage and receive back through flags | 2019-03-14T12:24:01.068000 | Russel |
elmlang | general | Mainly, I’d just need to have tokens stored for now | 2019-03-14T12:24:42.068200 | Russel |
elmlang | general | If your whole model is not what you _really_ need to persist, this seems more reasonable. | 2019-03-14T12:24:47.068400 | Timika |
elmlang | general | Thanks <@Timika> | 2019-03-14T12:25:03.068700 | Russel |
elmlang | general | <https://ellie-app.com/4YsDM2LML9ja1> | 2019-03-14T12:26:17.070000 | Lynne |
elmlang | general | Just tried out sending and receiving non-primitives :slightly_smiling_face: | 2019-03-14T12:26:27.070400 | Lynne |
elmlang | general | Am I correct that sending port message from JS to Elm is a synchronous operation? | 2019-03-14T12:26:37.070700 | Frieda |
elmlang | general | <@Lynne> I’ve seen this working, I think I was tripped up when attempting to use union types. But as <@Timika> pointed out, if your model structure changes or types get renamed, and you are relying on the default JD/JE implementations, then it could easily break compatibility. So, I settled on the idea of keeping only a small part of my state in LocalStorage which could be a record of maybe types, then I won’t have to reimplement JD/JE for that specific part of the app. | 2019-03-14T12:29:52.071100 | Russel |
elmlang | general | How do i specify init that will call an update? | 2019-03-14T12:30:31.071300 | Wendy |
elmlang | general | This may lead to some duplication in my model, or I will not store this state in my model and only use it as a flag | 2019-03-14T12:30:53.071400 | Russel |
elmlang | general | Nah, I am not questioning what <@Timika> said (on contrary, I am fully supporting it). The Ellie was to check if the docs were up-to date because I got concerned about what <@Timika> said about dropped support for sending non-primitives to ports | 2019-03-14T12:31:32.072100 | Lynne |
elmlang | general | calling `update` from `init` sounds like an attempted solution to a problem. There may be other, better solutions to that problem. | 2019-03-14T12:31:42.072500 | Huong |
elmlang | general | Sadly, but sometimes docs are not saying true | 2019-03-14T12:31:50.072600 | Lynne |
elmlang | general | Yup, i was wrong about that :smile: | 2019-03-14T12:31:54.072800 | Timika |
elmlang | general | yes | 2019-03-14T12:32:04.073000 | Huong |
elmlang | general | thank you | 2019-03-14T12:32:22.073500 | Frieda |
elmlang | general | Is this knowledge about an implementation detail or part of the “spec”? | 2019-03-14T12:33:53.074800 | Timika |
elmlang | general | <@Wendy> `update` is just a function which may modify model and produce a command. Init has same power as it can modify the model and produce a command. If you want to reuse some update model logic then you can extract the logic in a helper function and use the helper function in both init and update functions. | 2019-03-14T12:34:33.075700 | Frieda |
elmlang | general | It was consciously changed in 0.19, to make it possible to pass certain things (like event data) through ports and react to those, which must (in many cases) happen synchronously | 2019-03-14T12:35:29.075900 | Huong |
elmlang | general | I checked the source code briefly it all it does is just pure function calls. | 2019-03-14T12:35:31.076100 | Frieda |
elmlang | general | so as far as I'm concerned, that's "spec", in the sense that it's not a coincidence | 2019-03-14T12:36:08.076300 | Huong |
elmlang | general | Yeah, same for me. Thank you for elaborating this! :slightly_smiling_face: | 2019-03-14T12:36:33.076500 | Timika |
elmlang | general | Agreed, that is super cool. | 2019-03-14T13:16:53.076900 | Dede |
elmlang | general | For what it's worth, I did one last pass and made my markdown system work entirely within the Parser operation. | 2019-03-14T13:17:16.077200 | Dede |
elmlang | general | There is no large-scale backtracking, although backtracking is used in tokenization. Most of it could be squeezed out if it were a performance issue. | 2019-03-14T13:18:07.077500 | Dede |
elmlang | general | My completed homework assignment is here: <https://github.com/jhbrown94/elmish-minimarkdown> | 2019-03-14T13:18:15.077700 | Dede |
elmlang | general | Now back to the primary project :wink: | 2019-03-14T13:18:21.077900 | Dede |
elmlang | general | How to make two work days disappear :laughing: | 2019-03-14T13:19:04.078100 | Velia |
elmlang | general | Oh yeah. | 2019-03-14T13:19:23.078300 | Dede |
elmlang | general | Brainsnipe. | 2019-03-14T13:19:25.078500 | Dede |
elmlang | general | But I had been looking for an excuse to learn Elm Parser. | 2019-03-14T13:19:34.078700 | Dede |
elmlang | general | This will pay back I'm sure. | 2019-03-14T13:20:00.078900 | Velia |
elmlang | general | :wink: | 2019-03-14T13:20:05.079100 | Dede |
elmlang | general | All said and done, I think I still prefer parser-generator systems (e.g. Bison/Yacc) because the domain-specific language is so well tailored to parsing. | 2019-03-14T13:20:30.079300 | Dede |
elmlang | general | <@Frieda> i ended up having let in init functions and gradually built the model structure. The function that was used in init model now can take model as the argument and i can refactor my code | 2019-03-14T13:20:31.079500 | Wendy |
elmlang | general | (Also: I'll bet the regexp version wins for performance because it's probably a C implementation somewhere deep inside Node.) | 2019-03-14T13:26:19.079700 | Dede |
elmlang | general | This ended up being v nice. | 2019-03-14T14:44:30.080300 | Jeanene |
elmlang | general | For the purposes of validating whether somebody is 18, that constant-time check works well _enough_…and it provides a fairly clear/terse implementation IMO. Would love to know how to do it properly for leap years and whatnot, but I feel like this will check the vast majority…and if somebody fails a `is18` check, they can come back in a day or less and pass. :slightly_smiling_face: | 2019-03-14T14:45:48.080500 | Jeanene |
elmlang | general | :slightly_smiling_face: | 2019-03-14T15:45:50.080800 | Hoyt |
elmlang | general | Is elm-community/html-test-runner 0.19-compatible? Or is there something else to run tests in the browser? I was hoping to use Parcel to compile my tests and have them running in a tab next to my app. | 2019-03-14T15:56:23.082000 | Dorsey |
elmlang | general | See <https://github.com/elm-explorations/test> | 2019-03-14T16:26:42.082200 | Bebe |
elmlang | general | you can use npm install -g elm-test and then elm-test --watch | 2019-03-14T16:27:03.082400 | Bebe |
elmlang | general | That’s for the terminal, right? | 2019-03-14T16:28:48.083200 | Dorsey |
elmlang | general | yep | 2019-03-14T16:31:34.083400 | Bebe |
elmlang | general | i didn't realise you meant the html runner | 2019-03-14T16:31:47.083600 | Bebe |
elmlang | general | Yeah. Thanks for offering help :) | 2019-03-14T16:32:35.084600 | Dorsey |
elmlang | general | This seems to exist and be 0.19 compatible <https://package.elm-lang.org/packages/jgrenat/elm-html-test-runner/1.0.1/> | 2019-03-14T16:33:31.084800 | Bebe |
elmlang | general | That's interesting. Thanks! | 2019-03-14T17:08:51.085300 | Dorsey |
elmlang | general | i've been out of the elm world for a bit and it looks like `toString` is gone. what's the best way to convert a `List a` to a `String` now (assuming I can convert `a -> String`)? | 2019-03-14T17:47:03.086300 | Natalie |
elmlang | general | <@Natalie> if it's for debugging purposes then `Debug.toString` is still there | 2019-03-14T17:49:26.088500 | Earlean |
