hi guys, i'm wondering what's the figurine in the middle is supposed to represent. do you know ? https://www.stickermule.com/marketplace/15355-kotlin-with-flags

guys, I need to iterate over some collection but not from first index, and I don’t want to deal with indices at all. I know, in python there is an

enumerate(arr, fromId)

built-in function for that purpose:

for elem in enumerate(arr, 2): // elem = arr[2], arr[3] ... arr[n-1]

Is there something like that in kotlin std lib?

How can I catch that from a java caller?

Is it possible to map through a data class?

new Task;

, that's not really valid Java. Are you sure there's not some issue with the decompiler? Kotlin does sometimes generate bytecode that doesn't have a valid Java counterpart.

how is property ambiguity resolved? Cant find any info on that

Does anyone have experience with Jacoco and Kotlin? Does it work well? Is there some better tech out there for code coverage in Kotlin?

@poohbar ty, but if I base my API on that, then it will be more or less impossible to consume from Java, right?

In .NET, there is a

TaskCompletionSource<T>

which can be used to set results to a Task. My impression here is that

Deferred<T>

maps roughly to

Task<T>

in .NET, right? is there any way to get a Deferred that can be completed via code?

what is

1.1.3-2

? is it some sort of release candidate or an intermediate release?

huh, I just noticed that you can pass an empty lambda

{}

to a function expecting

() -> Any

because the lambda returns

Unit

which is a subtype of

Any

. That's ... interesting

Is any way to ensure calls to fun stored as a (val) class field are inlined? For example to pass in a comparator to a heap structure.

Hi guys, anybody knows if it's possible to do streams with kotlin, mainly the parallel process? i'm trying to make a parallel processing in android app in order to solve a computation quickly?

Is there a workaround for this issue?

class MyClass {
    var a: Int
    
    init {
        computeA()
    }

    private fun computeA() {
        a = 5
    }
}

The compiler complains that I have to initialize

a

, apparently it can't tell

computeA()

does initialize it.

Can someone help me with kotlinjs?

OMG i need to build it first

Constantly torn between

java.io.File

+ Kotlin extensions and

java.nio.file.Path/Files

without. Wish I wouldn’t need to make a choice between better API usability and better file system implementation.

Anyone have a good kotlin code style file can share with me ? thx

it works with

Any

if its not a

List

how can I submit a useful bug report for Refactor > Rename on a Kotlin class locking up my IDE?

I understand the reasoning for not including checked exceptions in the lang, but when it comes to java interop I need to deal with environmental errors somehow. So far I'm using my own biased Either, whose semantics I prefer over try/catch. That said, it's entirely dependent on my disciple to check if any java function I call throws some checked exception. Have any best practices emerged? Is there any linting or equivalent that can alert me to uncaught checked exceptions?

in the context menu I can only mark it as plain text 😕

Hmm, please stay on topic and within Kotlin context. 🚓

did something change? this worked at one point

We are porting Proto.Actor to Kotlin (http://proto.actor) https://github.com/AsynkronIT/protoactor-kotlin WiP atm, but things are looking great, especially perf using coroutines. If anyone is interested in this space, feel free to join the effort.

comparison to akka?

Is it possible to have a property override Java interface method? As in

String getName()

in interface would be implemented by

val name: String

property. I get

same JVM signature

error, although this SO answer suggests that having the property

private

would solve the problem: https://stackoverflow.com/questions/29268526/how-to-overcome-same-jvm-signature-error-when-implementing-a-java-interface

is that shallow copy is possible in kotlin? how come it works with copy()? while using data class?

Here it is in action
