val handler = { e: AudioPlayerEvent ->
    client.connectedVoiceChannels.find { it.guild == e.player.guild }?.leave() ?: Unit
}

on<TrackFinishEvent>(handler)

errors if I remove

?: Unit

, because handler does not conform to

(T) -> Unit

, because it's

(T) -> Unit?

can this get changed? I mean, I can obviously do

{ handler() }

, or specify type of variable as returning Unit, but still

Copy code

val handler: (AudioPlayerEvent) -> Unit = { e ->

11/10/2016, 8:11 AM

don't think it is going to be changed

@krtko equivalent of

continue

array.forEach { return@forEach }

. Equivalend of

break

is more complicated:

Copy code

run {
    array.forEach {
        return@run
    }
}

is it expected that with the milestone releases, the IntelliJ plugin and the compiler are not agreeing on whether a program is correct? My IDE is bleeding all over the place even though the program compiles fine. I understand it’s a pre-release, just wondering whether it’s just something about my setup

the errors indicated by the IDE also suddenly seem to dis- and reappear

@mk this is most certainly related to you build being misconfigured

make sure your stdlib and plugin versions are the same

@User uploaded a file: Untitled and commented: IntelliJ complains that this isn’t tail-recursive. Is there something about

let

that I’m not getting, or just a compiler limitation at the moment?

@daniil yeah I think you might be right—I actually only noticed now that IJ was telling me that:

Copy code

Kotlin version that is used for building with Gradle (1.1-M02) differs from the one bundled into the IDE plugin (1.1-M02-12) less... (⌘F1)

However, when I set the Kotlin version to

1.1-M02-12

in build.gradle, it complains that there exists no such artifact

and I seem to be on the latest release —^

11/10/2016, 9:13 AM

what am I missing here?

11/10/2016, 9:13 AM

I’m pulling from https://dl.bintray.com/kotlin/kotlin-eap-1.1/

11/10/2016, 9:14 AM

and indeed there is no

1.1-M02-12

deployed to that repository

@cy yeah, as I said, I can specify the type of variable, but that's kinda long. was being able to pass any (T) -> R as (T) -> Unit ever discussed?

11/10/2016, 10:33 AM

yes, I remember it was

11/10/2016, 10:33 AM

let me check if we have a ticket about it

11/10/2016, 10:39 AM

@cypher121 For sure it is related one: https://youtrack.jetbrains.com/issue/KT-11723
