I'm trying to implement a language client in vscode, in the recent versions of the languageclient library you're supposedly supposed to use an import like
import { LanguageClient } from 'vscode-languageclient/node';

and this page https://scalablytyped.org/docs/encoding suggests I import something like typings.vscodeLanguageclientNode.LanguageClient, but that vscodeLanguageclientNode part doesn't seem to exist - what could I be doing wrong?

also, did this gitter survive the discordapocalypse??

I'm not aware of any ST discord, and you can see there are recent messages including by the maintainer

Jakub Kozłowski

@kubukoz

indeed

anyway, this is my dependency "vscode-languageclient": "8.0.2" and I'm kinda shocked that I'm not seeing that node import in completions or anything

it was working so well before :sweat_smile:

looks like I'm not getting a node-mentioning jar at all

Jakub Kozłowski

@kubukoz

aight, gonna submit an issue with all the deets

Øyvind Raddum Berg

@oyvindberg

I'd be happy to move the channel to discord. I didn't proceed with it since there wasn't a "create new channel" button :D

Naftoli Gugenheim

@nafg

yeah, it's a choice between starting yet another server, and bothering admins of an existing server to create a channel for you

Øyvind Raddum Berg

@oyvindberg

right, hehe

so it'll remain here a bit longer I guess

the best effort is no effort

@kubukoz looks like it's only translating the common folder inside vscode-languageclient, and drops browser and node. The reason is that it follows the typings entry in package.json

IOW do file an issue so it can be tracked. there is a lot of weird things going on at the top-level of javascript libraries, like this

Jakub Kozłowski

@kubukoz

I'm happy to bother the Scala admins to create a channel ;)

Made ScalablyTyped/Converter#463, in the meantime I'm doing manual facades so I'll be fine

where I'm going I'm probably not going to need Scala.js :sweat_smile:

hiya all! fair warning, i know almost nothing about scala, but ST was so overly cool i had to try it. I believe I've found a package that doesn't convert properly, but before I follow the site's instructions and submit an issue, I was hoping I could get a bit of help confirming it actually is an issue

I have hte example react-router-dom and @types for it working, but adding pixi.js showers me in logs I don't understand

[error] java.lang.RuntimeException: FromFolder(InFolder(/home/kc/workspace/scala/pixala/target/scala-2.13/scalajs-bundler/main/node_modules/pixi.js),TsIdentLibrarySimple(pixi.js)) -> Right(Compilation failed: )

this is the root error prior to stack trace

Casey Bailey

@SonicZentropy

ah nevermind, intellij was eating the error log i actually needed, it is indeed a bug

Øyvind Raddum Berg

@oyvindberg

@kubukoz feel free to, it'd be cool to have the channel on say the scala discord instead

@SonicZentropy feel free to open an issue if you couldnt resolve it

Has anyone here ever used interactjs with scalablytyped?

I am having a bit of trouble finding the right entrypoint

I wrote a facade for it a couple years back, but I wanted to give scalablytyped a go since there have been some updates to interactjs recently and the api is to complex to fully maintain on my own.

I found that I can import typings.interactjsInteract.mod.{default => interact} and then calling interact(".foo").draggable() works, but it's return type is wrong. It returns Any while the library defines it as returning another library object to facilitate chain calling.

Øyvind Raddum Berg

@oyvindberg

(this: Interactable, options: Partial<OrBoolean<T>> | boolean): typeof this; I never cease to be surprised what they come up with!

the typeof this ends up being any

@busti

So I wasn't going crazy then 😮‍💨
Thanks a lot for the quick reply. The typings of interactjs seem to be absolutely wild, because scalablytyped generates an absolute ton of confusing stuff.
I assumed it was working at first because I got a confusing error message in the browser console, but now I cannot get it to do anything at all.
The typings.interactjsInteract.mod.{default => interact} import definitely works, because printing it to the console yields a method that just makes sense.

However, calling any method on it, i.e. .draggable causes the frontend to just hang indefinitely.
The .apply method of the DraggableOptions object that has to be passed to the .draggable method also has no arguments.

I have no idea what's going on here.

Is there maybe another entrypoint that makes more sense to use?

@oyvindberg we got to play with https://github.com/oyvindberg/st-material-ui/tree/master/st-material-ui-slinky which has worked nicely, I just wonder if you happen to have examples for styling components, by default, we can propagate CSSProperties but it can be annoying

Øyvind Raddum Berg

@oyvindberg

@busti DraggableOptions is meant to be mutated after you call apply, see https://scalablytyped.org/docs/objects

cool @AlexITC . I havent done any work on that part yet. I would need help with coming up with a nice way to integrate styled components -like libraries with the reactcomponents output from the ST flavours

Alexis Hernandez

@AlexITC

Thanks for sharing, let's see where we can get

@busti

@oyvindberg Ah, I did not see the setter methods on that object.
Doesn't matter though, since I cannot pass it to the .draggable method since the compiler cannot find the right method for that parameter.

[error] /<path>/foo.scala:60:16: overloaded method draggable with alternatives:
[error]   (options: typings.std.Partial[typings.interactjsTypes.typesMod.OrBoolean[typings.interactjsTypes.pluginMod.DraggableOptions]])Any <and>
[error]   (options: Boolean)Any
[error]  cannot be applied to (typings.interactjsTypes.pluginMod.DraggableOptions)
[error]               .draggable(draggableOptions)
[error]

The type signature of the .draggable method is also plenty weird.
options: Partial[OrBoolean[DraggableOptions]]
From what that sounds like, I should just be able to pass a DraggableOptions object, right?

Finally, I am unable to set an event listener on the DraggableOptions object, since it's setOnmove method expects a

type ListenersArg = typings.interactjsTypes.typesMod._ListenersArg | (js.Array[
    typings.interactjsTypes.typesMod.Listener | typings.interactjsTypes.typesMod.ListenerMap
  ])

and following those types just leaves me with a trait _ListenersArg extends StObject or

@js.native
trait Listener
  extends StObject
     with _ListenersArg {

  def apply(args: Any*): Any = js.native
}

@busti

I am sorry if I am asking questions with obvious answers. I just cannot make heads or tails of this. I have tried reading the docs of scalablytyped and looked at all the examples, but none seem to be this confusing.

Øyvind Raddum Berg

@oyvindberg

I think it's fair to accept that some libraries are too weirdly defined to 1-1 translate, this seems to be one of them

in that case a valid approach is to generate source code with ST to get a starting point, and then refactor it until it's workable

typings.std.Partial[typings.interactjsTypes.typesMod.OrBoolean[typings.interactjsTypes.pluginMod.DraggableOptions]] for instance is very javascripty

it looks like you can supply a subset of the fields in (DraggableOptions | boolean) because Partial, whatever that means

ST has support for evaluating statically the type for Partial<DraggableOptions>, but not Partial<DraggableOptions | boolean> (if that is what OrBoolean does)

and Listener is awkward because it's an untyped vararg function. there is no good scala syntax for that

Øyvind Raddum Berg

@oyvindberg

FTR casts will get you out of both situations. you can cast a js.FunctionN to Listener safely, and you can cast DraggableOptions to that weird type

moritz bust

@busti

I am guessing that this would be right?

interact(element).draggable(
        DraggableOptions()
          .setOnstart(((event: InteractEvent) => println(event)).asInstanceOf[ListenersArg])
          .asInstanceOf[Partial[OrBoolean[DraggableOptions]]],
      )

While that does compile, it does not run. Javascript complains that:

scala.scalajs.js.JavaScriptException: TypeError: $$x1.draggable is not a function
