elmlang | general | The whole App? | 2019-03-12T11:21:14.857900 | Corinne |
elmlang | general | The port, so it won’t appear in `app.ports`. | 2019-03-12T11:22:02.858500 | Jin |
elmlang | general | but `app.ports` is `undefined` | 2019-03-12T11:22:13.858800 | Corinne |
elmlang | general | Unless.. .that's expected? | 2019-03-12T11:22:31.859400 | Corinne |
elmlang | general | you gotta wire them up on the Elm side | 2019-03-12T11:23:43.859700 | Rosa |
elmlang | general | Ah, right so a completely empty object for `app` is normal | 2019-03-12T11:25:11.861000 | Corinne |
elmlang | general | If you never use any incoming port in your `subscriptions` function used in `main` nor any outgoing port in `init` or `update`, then `app.ports` will be undefined because the elm compiler will have optimized those away (as they are never called) | 2019-03-12T11:25:55.861900 | Mindy |
elmlang | general | Cool, thanks. I guess I was expecting _something_ to be in that object, or maybe a `[]` for `ports`, but I see now | 2019-03-12T11:26:58.862700 | Corinne |
elmlang | general | Basically, `app` is just an object that may or may not have a `ports` field and `app.ports` is an object with one field per port called in the elm side.
If it is an outgoing port, it will have access to a `subscribe` and an `unsubscribe` method. If it is an incoming port it will have a `send` method. | 2019-03-12T11:30:55.865500 | Mindy |
elmlang | general | using `/` as the italic symbol in combination with `/` as division and `//` in url's isn't possible normally. Why is `/` the symbol for italic (thought it was a single `*`, or `_`) | 2019-03-12T11:39:27.865900 | Virgie |
elmlang | general | None | 2019-03-12T11:42:42.866100 | Leoma |
elmlang | general | <@Virgie> <https://bear.app> parses this way :point_up:. It’s more intuitive for people who don’t understand markdown. | 2019-03-12T11:42:47.866500 | Leoma |
elmlang | general | In my implementation, modifiers (/*) only count if the modifiers have whitespace on the left-but-not-right to open, and right-but-not-left to close. | 2019-03-12T11:43:52.867000 | Dede |
elmlang | general | It covers most cases. | 2019-03-12T11:43:55.867200 | Dede |
elmlang | general | `(5 / 4) ` also parses fine with that. | 2019-03-12T11:44:09.867400 | Dede |
elmlang | general | My math is a bit off. :blush: | 2019-03-12T11:44:27.867700 | Leoma |
elmlang | general | my guess is then that the url is parsed differently | 2019-03-12T11:44:33.867900 | Virgie |
elmlang | general | as in, a url is not text, it is its own thing | 2019-03-12T11:44:45.868200 | Virgie |
elmlang | general | Yes. | 2019-03-12T11:44:58.868400 | Leoma |
elmlang | general | But it can also be styled. | 2019-03-12T11:45:44.868600 | Leoma |
elmlang | general | None | 2019-03-12T11:45:50.868800 | Leoma |
elmlang | general | does something like `ftp://` also parse as a url? or just `http[s]`? | 2019-03-12T11:46:00.869200 | Virgie |
elmlang | general | I mean, once one has a the code for one, the other is easy to add. My target is very simple markdown I can explain to non-savvy users is a single example. `"*this will be bold* /this will be italic/" <http://clickme.com>"` I think most people won’t know or care about ftp. | 2019-03-12T11:48:10.870100 | Leoma |
elmlang | general | Anyway, I have some pseudo code I like. Off to the battlefield to see where this goes. Back in a bit and thanks to everyone for their help so far. | 2019-03-12T11:50:51.872600 | Leoma |
elmlang | general | is there any way to "namespace" a bunch of type constructors? I want to import a type `S` but have the type constructors accessed on `S`, e.g. `S.Value`. Maybe there's a clever trick that I don't know...
```
module Values exposing (S(..))
type S = A | B | C
...
module Main
import Values exposing (S)
defaultModel =... | 2019-03-12T11:51:33.873300 | Kymberly |
elmlang | general | To my knowledge constructors are on the same level of visibility of the type. | 2019-03-12T11:53:37.874000 | Hoa |
elmlang | general | If you constructors have generic names consider to add a suffix or prefix to them. E.g. `type BlendMode = MultiplyMode | OverlayMode | ... ` instead of generic `Multiply` or `Overlay`. | 2019-03-12T11:55:20.875600 | Hoa |
elmlang | general | In your example I would write `Values.A` | 2019-03-12T11:56:20.876200 | Hoa |
elmlang | general | Constructors are namespaced by the name of their module, not their type :+1: | 2019-03-12T11:58:54.876900 | Carman |
elmlang | general | Any package for AES Symmetric Encryption? | 2019-03-12T12:07:20.878700 | Brady |
elmlang | general | I want to exchange keys with node.js and send encrypted messages between server and Elm app | 2019-03-12T12:08:23.879600 | Brady |
elmlang | general | I can use ports, but I'd like to do that in Elm if possible | 2019-03-12T12:08:49.880200 | Brady |
elmlang | general | Is there any tool that checks if dependencies listed in `elm.json` are actually used? | 2019-03-12T12:11:21.881400 | Dorsey |
elmlang | general | <@Dorsey> <https://github.com/stil4m/elm-analyse> | 2019-03-12T12:11:51.882000 | Brady |
elmlang | general | Elm parser question: how would one implement a grammar fragment of this form?
```
textSquence = textNoWhitespace | textSequence whitespace textNoWhitespace
``` | 2019-03-12T12:12:21.882800 | Dede |
elmlang | general | (idiomatically?) | 2019-03-12T12:12:33.883200 | Dede |
elmlang | general | <@Brady> Other ppl are using this: <https://package.elm-lang.org/packages/billstclair/elm-crypto-aes/latest/> | 2019-03-12T12:12:38.883400 | Hoa |
elmlang | general | Not expert, tho. Might well be it has limits :slightly_smiling_face: | 2019-03-12T12:13:06.884000 | Hoa |
elmlang | general | <@Hoa> I was looking at that but cannot figure how to import shared key, but thanks! | 2019-03-12T12:13:40.884600 | Brady |
elmlang | general | Thanks <@Brady> (and <@Shea> of course) | 2019-03-12T12:29:42.884700 | Dorsey |
elmlang | general | Test case question: `/* hello*/` Does this get italics or not? :wink: | 2019-03-12T12:30:46.884900 | Dede |
elmlang | general | So, I’m not super fussy about edge cases, but I suspect the simplest parser that mostly works will parse that as `Italic "* hello*"` (or however the type is represented) | 2019-03-12T12:35:48.885200 | Leoma |
elmlang | general | Broader question: Elm Parser mostly advertises itself as a replacement for regexps, rather than, say, for BNF-driven parser generators (e.g. yacc/bison.) Do people use it in the latter manner as well, or mostly hand-write parsing once the Parser has handled tokenization? | 2019-03-12T12:58:37.886700 | Dede |
elmlang | general | Update: I believe I’ve found a fast manual way to to this without Parser or Regexp. Will share if/when it works. (Very Fermat-esque statement.) | 2019-03-12T14:20:42.886800 | Leoma |
elmlang | general | parser combinators are usually used to parse straight into an AST, so no separate lexer/parser, thing. So yeah, elm/parser type parsers are definitely used as a replacement for BNF-driven parser generators | 2019-03-12T14:52:37.887100 | Huong |
elmlang | general | Thanks. Formally does that wind up being in the LL top-down family of parsers, then? | 2019-03-12T14:57:28.887400 | Dede |
elmlang | general | Yeah, pretty much | 2019-03-12T15:05:26.887600 | Huong |
elmlang | general | As a nontrivial example of something that's parsed using parser combinators: our dearly beloved `elm` compiler parses Elm using parser combinators :slightly_smiling_face: | 2019-03-12T15:06:39.887800 | Huong |
elmlang | general | :wink: | 2019-03-12T16:02:38.888100 | Dede |
elmlang | general | In Haskell or elm? | 2019-03-12T16:48:12.888500 | Dede |
elmlang | general | Haskell, though Elm can be parsed using `elm/parser`, in Elm, too - `stil4m/elm-syntax` does just that | 2019-03-12T16:49:33.888700 | Huong |
elmlang | general | I'm trying to get the error message out of `Json.Decode.fromValue`, and the docs _say_ it's a `Result String a` but when I `Debug.log` it it's `Err (Failure "Expecting an OBJECT with a field named `accessTokens`" <internals>)` | 2019-03-12T16:51:47.890000 | Kymberly |
elmlang | general | are the docs misleading or am I doing something wrong there? | 2019-03-12T16:52:13.890400 | Kymberly |

elmlang | general | You must be looking at the wrong package docs | 2019-03-12T16:58:21.893100 | Earlean |
elmlang | general | dang I must've checked that I was on latest a dozen times - but prob on another package page. | 2019-03-12T17:02:27.893500 | Kymberly |
elmlang | general | thx! | 2019-03-12T17:02:29.893700 | Kymberly |
elmlang | general | Huh, I was looking at <https://package.elm-lang.org/packages/elm-lang/core/latest/Json-Decode> | 2019-03-12T17:03:03.894200 | Kymberly |
elmlang | general | Yep, that's docs for the core package for Elm 0.18 | 2019-03-12T17:05:17.895200 | Earlean |
elmlang | general | oh yikes - I'll have to keep an eye for "packages/elm-lang" - it shows up in a google search. :confused: | 2019-03-12T17:08:00.896100 | Kymberly |
elmlang | general | If you search via <https://packages.elm-lang.org> you'll only get 0.19 packages | 2019-03-12T17:14:34.897200 | Earlean |
elmlang | general | Older packages will come up in Google searches | 2019-03-12T17:15:02.897800 | Earlean |

elmlang | general | About to have dinner, but I’ll leave you with this <https://gist.github.com/z5h/493423f87f77bbdcf886159b21a3dc87>
Should I feel bad I’m now using regexs? I think I’m using them responsibly. | 2019-03-12T17:33:20.898400 | Leoma |
elmlang | general | Does it work? Is it maintainable? If so, it’s good enough for prod :wink: | 2019-03-12T17:50:47.898700 | Dede |
elmlang | general | Eventually yes and yes. But I’m mildly um bothered by the fact the elm/parser didn’t make it easier. | 2019-03-12T18:39:19.900200 | Leoma |
elmlang | general | I don't think that such a markdown can have very simple rules and be very practical at the same time.
For example have a look at the commonMark specification that tries to give a synthesis of the reasonable rules:
<https://spec.commonmark.org/0.28/#emphasis-and-strong-emphasis>
Not that simple...
I would not go the r... | 2019-03-12T18:55:50.900400 | Velia |
elmlang | general | I just pushed a big overhaul to <https://github.com/jhbrown94/elmish-minimarkdown> It’s still not a pure Elm Parser implementation, but it’s a lot cleaner than the first pass.s | 2019-03-12T19:23:06.900700 | Dede |
elmlang | general | (As before, right now it just supports italic and bold.) | 2019-03-12T19:23:57.900900 | Dede |
elmlang | general | But it handles all the goofy cases reasonably well IMHO. | 2019-03-12T19:24:10.901100 | Dede |
elmlang | general | Think this is a readable function?
```

elmlang | general | I might do something like
```
Iso8601.toTime (year ++ "-" ++ month ++ "-" ++ day)
|> Result.map (\value -> 568025136000 < (currentTime - Time.posixToMillis value))
|> Result.withDefault False
``` | 2019-03-12T19:31:18.902700 | Hoyt |
elmlang | general | Although I would probably pull that lambda into an actually function like `greaterThan18` to make it more clear what that is comparing | 2019-03-12T19:33:35.903900 | Hoyt |
elmlang | general | Or at least something like
```
millisecondsIn18years = 568025136000
``` | 2019-03-12T19:34:04.904500 | Hoyt |
elmlang | general | I’ll try this out tomorrow and report back! | 2019-03-12T19:35:18.904900 | Jeanene |
elmlang | general | <@Jeanene> that milliseconds seems wrong. For example 568,015,222,000 < 568,025,136,000, but it's exactly 18 years ago today | 2019-03-12T20:06:51.907000 | Chae |
elmlang | general | today != now…I think I got the ms from `18.years.ago.to_i` in ruby :smile: :sweat_smile: | 2019-03-12T20:08:17.907700 | Jeanene |

elmlang | general | Is there an easy way to get a zero value'd record without making it myself? i.e.: ```type alias Thing = { x : Int, y : Maybe String }```, then ```getZeroValue Thing``` returns ```{x=0, y=Nothing}```. I strongly feel like the answer is no, but I'm praying otherwise :stuck_out_tongue: | 2019-03-13T03:08:32.911400 | Nga |

elmlang | general | The answer is no, sorry :slightly_smiling_face: | 2019-03-13T03:10:36.912200 | Lynne |
elmlang | general | awwww, heh. thanks | 2019-03-13T03:11:14.912400 | Nga |
elmlang | general | <@Nga> a 'zero value' isn't meaningful for a lot of types | 2019-03-13T03:17:34.913200 | Earlean |
elmlang | general | What would you use this behaviour for? | 2019-03-13T03:18:27.914200 | Earlean |
elmlang | general | <@Earlean> I have a bunch of record types that define API responses. When I don't have an API response, I have it as `Maybe ApiRespObj`, but once I've received the object I transition my state from a `Maybe ApiRespObj` to just a `ApiRespObj`, so that it's easier to work with in my views. The conversion from the Maybe t... | 2019-03-13T03:21:03.916500 | Nga |
elmlang | general | Ah, that is a common mistake. Don't convert a Maybe to a nonsense default value. Just use `Maybe.map` etc. to work with the Maybe | 2019-03-13T03:24:32.918700 | Earlean |
elmlang | general | Right. it's a bit of a shame because I've modeled the data in such a way that it can only ever have a correct value at that point (we have a union type that declares the state of the app, whether its Loading, Loaded, an error, etc). By using Maybe's as my Loaded values it doesn't make a lot of sense since that's not ac... | 2019-03-13T03:35:54.920500 | Nga |
elmlang | general | Or if it's just a limitation problem that we have to accept. | 2019-03-13T03:36:33.920800 | Nga |
elmlang | general | A `Maybe a` that can't be Nothing should just be an `a`, right?
I'm just guessing of course, but I'd look higher up if the Maybe can be avoided before giving it to the function that doesn't expect any Nothings. | 2019-03-13T03:58:52.921100 | Sharon |
elmlang | general | <@Sharon> We have something like: `{settings = Maybe ApiSettingsResponse, profile = Maybe ApiProfileResponse}`. Can't set them to just `a` because then it's the same problem again (zero initialization before the API request returns). | 2019-03-13T04:01:40.922400 | Nga |
elmlang | general | Settings and Profile seems like something which you get once at the very start. If that is the case it may be a good idea to postpone initialization of page/view which depends on these and only init it when you receive them. In this case you won't need `Maybe`s. | 2019-03-13T04:06:02.923600 | Lynne |
elmlang | general | <@Nga> so if they can't be Nothing when you're `Loaded` then that's the time to unwrap them, if any of them are Nothing then you're still in the `Loading` state | 2019-03-13T04:18:26.926200 | Earlean |
