I just finished updating my application from 0.18 and 0.19, but using `--optimize` only gets the compiled file from 1.2MB to 1.1MB. I guess I was expecting more. Could I be doing something wrong?

2018-12-31T04:52:41.387200

Fred

elmlang

<@Fred> `--optimize` doesn't minify but it does have an output that is easier to minify <https://guide.elm-lang.org/optimization/asset_size.html#instructions> provides the best command for minifying

Happy new year all. I'm wondering why in the Elm docs, it is so discouraged to write effect manager helpers? If I knew why it was discouraged, it might give me an idea for how to implement some kind of alternative. <https://package.elm-lang.org/packages/elm/core/latest/Platform>

2018-12-31T07:56:50.390600

Santina

I don't think you even CAN write an effect manager since 0.19

2018-12-31T08:02:58.392100

Mirian

elmlang

It seems possible given the documentation,

2018-12-31T08:03:09.392300

Santina

elmlang

unless the documentation is outdated

2018-12-31T08:03:12.392500

Santina

elmlang

Yeah I think this is outdated but somebody got to confirm this

2018-12-31T08:03:37.392700

Mirian

elmlang

As to why - we loose all guarantees that elm gives us when we just wrap js code

2018-12-31T08:04:50.392900

Mirian

elmlang

general

If you need to access some js library ports are the way to go

2018-12-31T08:06:49.393100

Mirian

elmlang

general

effect managers are not necessarily using JS code though. The main problem with them is that they store state outside of the model. This does indeed break the nice guarantees that elm otherwise provides. They are also discouraged because they are the "easy" solution, thinking about the problem harder in an elm context likely gives a better solution

I'm trying to write a shrinker (elm-explorations/test v1.2.0) for my own data structure but fail to import module 'Lazy.List' ("I cannot find that module!"). Importing module 'Shrink' works without problems. Any ideas?

2018-12-31T08:44:20.395900

Lavonna

elmlang

general

looks like it is not exported. Do you need anything besides the type signature? (also try <#C0CLGCMMF|testing> )

2018-12-31T08:48:21.396500

Virgie

elmlang

general

Where do you get the info from that it is not exported? (-&gt;Where should I look to find this out myself?) I thought I need it because the 'Shrink' doc (<https://package.elm-lang.org/packages/elm-explorations/test/1.2.0/Shrink>) says a shrinker should produce a lazy list and I had a look at the provided implementations. Can I produce any kind of lazy list (maybe from other packages)?

2018-12-31T09:04:59.400100

Lavonna

elmlang

general

ah . . . "elm.json" in the package source contains the info, what modules are exposed

2018-12-31T09:08:11.400900

Lavonna

elmlang

general

in the docs <https://package.elm-lang.org/packages/elm-explorations/test/latest/Shrink#lazylist> exposed types are blue/clickable. `LazyList` isn't

2018-12-31T09:17:43.401400

Virgie

elmlang

general

not true - for example `Shrinker` is exposed but not blue/clickable

2018-12-31T09:19:44.401500

Howard

elmlang

Hmm, that did work before. Might be dropped in 0.19

2018-12-31T09:26:16.401700

Virgie

elmlang

general

also it does work for `elm/core` <https://package.elm-lang.org/packages/elm/core/latest/String>

2018-12-31T09:26:41.401900

Virgie

elmlang

maybe it only works for types and not aliases?

2018-12-31T09:27:28.402100

elmlang

Can someone explain what is meant by “effect manager”?

2018-12-31T09:32:48.402400

Rosalee

elmlang

general

they are something used in the implementation of subscriptions and commands, for instance the browser package uses them for keyboard and mouse events <https://github.com/elm/browser/blob/1.0.1/src/Browser/Events.elm#L246>

2018-12-31T09:47:22.402700

Virgie

elmlang

general

but, like native code, they break guarantees and thus can only be used by the core team in specific packages

2018-12-31T09:47:50.402900

Virgie

elmlang

general

thx - wasn't aware that the links correspond to the exposed types

2018-12-31T10:01:00.403100

Lavonna

elmlang

general

Although in my special case (at most one possibility ever) I would conceptually get away with a regular list, the compiler insists on a 'Lazy.List.LazyList' . . . is there a more elegant way to solve this, than to replicate/copy the corresponding non-exposed code from 'elm-explorations/test'?

2018-12-31T10:37:38.406000

Lavonna

elmlang

general

really depends on the specifics I think. The folks in <#C0CLGCMMF|testing> will know more (also sharing the specifics might help)

Is there any reason why you cannot use `Html.Attributes.property` (or `VirtualDom.property`) to set an element's `innerHTML` value in 0.19?

2019-01-01T22:18:55.423500

When I ported our 0.18 code to 0.19, that line stopped working

I can set a different attribute, e.g. if I change `property "innerHTML" (Json.Encode.string stringVal)` to `property "innerText" (Json.Encode.string stringVal)`, it will work

2019-01-01T22:20:08.424800

`innerHtml` is specifically forbidden in source: VirtualDom.elm - <https://github.com/elm/virtual-dom/blob/5a5bcf48720bc7d53461b3cd42a9f19f119c5503/src/VirtualDom.elm#L167> kernel code - <https://github.com/elm/virtual-dom/blob/5a5bcf48720bc7d53461b3cd42a9f19f119c5503/src/Elm/Kernel/VirtualDom.js#L289>

2019-01-01T22:32:14.428700

Earlean

elmlang

you can use Elm unicode escapes, for example `"\u{00A0}"` for non-breaking space (but granted this isn't as simple as using html escapes)

2019-01-01T22:32:21.429000

2019-01-01T22:32:45.429500

I am looking at the documentation for Random (<https://package.elm-lang.org/packages/elm/random/latest/Random>); and see that the signature for `generate` is `generate : (a -&gt; msg) -&gt; Generator a -&gt; Cmd msg`; is there a name for the (a -&gt; msg) part? Asking because I want to pass my random function a `(a -&gt; msg)`

2019-01-02T17:20:48.456300

it is often a (partially applied) constructor of your `Msg` type

2019-01-02T17:22:59.456700

Virgie

elmlang

general

so if `Msg = Thing1 Int Int | Thing2 String` then `Thing1 42` and `Thing2` are both values of type `something -&gt; Msg`

2019-01-02T17:23:49.457600

Virgie

elmlang

and `Thing1` and `Thing2` are the constructors of `Msg`

2019-01-02T17:24:00.457900

Virgie

elmlang

Ah, ok, thanks! Constructor makes sense. This makes the signature of the function I am working on look like: ``` generatePassword : (String -&gt; Msg) -&gt; Cmd Msg generatePassword msgConstructor = ```
