I'll need to find another way then

is there a way to link to a extension function in KDoc?

@zak.taccardi Doesn't linking to the method like you would otherwise just work?

oh yeah it does, haha. Thanks (my bad)

Hi All, i hope you are having a good weekend. I have started to learn kotlin language from https://try.kotlinlang.org/ I am getting difficulty to understand this part from the given code : https://try.kotlinlang.org/#/Kotlin%20Koans/Conventions/For%20loop/Task.kt In the below code snippet what is the exact meaning of

handler: (MyDate) -> Unit

argument , how this works? Anybody has idea about it? Any source to learn more about this kind of arguments?

fun iterateOverDateRange(firstDate: MyDate, secondDate: MyDate, handler: (MyDate) -> Unit) {
    for (date in firstDate..secondDate) {
        handler(date)
    }
}

@samp

(MyDate) -> Unit

means a function that takes a

MyDate

and returns nothing (

Unit

). That is the type for the argument

handler

.

Having a bit of trouble figuring this out

I have a field in a delegate that I'd need to use at some point in order to write the delegated value to disk, is there any way to actually access it?

Hey Kotlinerds. I'm running into what I would consider a bug unless I'm missing something. Having trouble reproducing it; not sure of the root cause. Let me know if this rings a bell or would make sense: I have a private inline function in an abstract class:

ifActorThreadIsAvailable(action: (complete: () -> Unit) -> Unit)

And this works as expected. But when I call it through a non-inline function in the same class (no issues calling through another inline) it explodes:

NoClassDefFoundError: mypkg/AbstractActor$ifActorThreadIsAvailable$1

. The non-inline function contains a call like this

ifActorThreadIsAvailable { complete -> ...

Does the

$1

mean it's failing to find an internal anonymous lambda class or something? Thanks

@alexreidy Can you do a minimal repro

@User uploaded a file: Untitled

I have a kotlin program which reads from stdin and ouputs something. It works fine if I run it from IntelliJ, but not if using

./gradlew run -q

@User uploaded a file:

As you can see the ouput is not where it should be 😕 any ideas?

Have you tried running it in a real terminal? Can you show us the source code? Do you happen to be on Windows?

Not sure what do you mean with real terminal, I've tried on both Tilix and GNOME terminal and the result is the same. I'm on Fedora.

@User uploaded a file: Untitled

I don't have much experience with Tilix or Gnome, but could it be that they simply don't automatically put a newline after you've input somthing?

The Idea terminal certainly does that.

but the first

print

is also wrong, since as you can see it puts a

\n

that shouldn't be there

Hmm right.

What happens when you run

./gradlew run -q

in Idea's terminal?

I get the same strange behavior

To make stdin work I've also added

run { standardInput = <http://System.in|System.in> }

to my

build.gradle

without the

-q

options

It seems to be a gradle problem https://issues.gradle.org/browse/GRADLE-1147

Ah all right.

It works with `--console plain`👍

I'm really puzzled. Here's the stack trace
