yeah, Double and NaN, welcome to hell…

and I'm actually kinda disappointed that

setOf(NaN, NaN).size

returns

1

Hi. How it is the proper way to init a weak reference on Kotlin?

Can kotlin merge multiple exceptions in one catch?

Try

java.lang.Void.TYPE

. To format code in Slack, wrap it into three backticks.

Is there a way to reference the value being checked in a when statement? I could obviously store the value locally, just trying to be succinct.

when (someCalculatedValue()) {
   1 -> doSomething(/*use value here*/)
   else -> log("nothing")
}

Does anyone use Spock to test Kotlin code? If o, how do you create immutable data classes. I really would not want to pass 10 parameters via constructor 😞

@voddan you mean

kotlinx.html

?

seems like a workaround, but i still have to create an instance of BinarySameType if i want to pass it in as a parameter. Is there a more functional solution?

I got problems with a project using 1.1 regarding a kotlin JS module

@nulldev This seems to be a bug, please report it to kotl.in/issue

since I seem to have a couple of build experts around, have any of you guys seen this?

Error:Kotlin: Multiple values are not allowed for plugin option org.jetbrains.kotlin.kapt:output
Plugin "org.jetbrains.kotlin.kapt" usage:
  annotations <path>         Annotation filter regular expressions, separated by commas
  output <path>              File in which annotated declarations will be placed
  stubs <path>               Output path for stubs
  inherited <true/false>     True if collecting Kotlin class names for inherited annotations is needed

I did use kapt but have since removed all references to it from my gradle build scripts and disabled annotation processing in intelliJ, yet when I do a

build

->

rebuild

in intelliJ, it still blows up with this error message 😞

is there a way to check that KClass is an enum directly (not calling .java.isEnum)?

<!channel> 📣 📣 📣 The one year wait is over, Kotlin 1.1 with coroutines, JS and quite a bit of small features is here! Please see details in blog post, https://blog.jetbrains.com/kotlin/2017/03/kotlin-1-1/ Those who were brave enough to try our pre-release builds – big thanks from the whole team to you! 👏 And don’t forget to update your dependencies to released build and publish your libraries to public repositories. Some people could be waiting for your library to be updated before they can jump on the release build. I would also like to take a chance of global announcement and thank every one of you for your support, community involvement, helping us shape the language and tooling around it, your support to newcomers, talks you’ve been doing, and otherwise spreading the word! We look forward to the next year of Kotlin evolution and adoption. With you!

@pawel.urban yes, it does. We already doing it at JetBrains.

I don't think I have ever seen more reactions in my life.

Is there a Gradle snapshot already which includes Kotlin 1.1 for KTS?

@cleiter As the compiler API was changed between Kotlin 1.0 and 1.1, you need to use the compatible plugin version (1.1) when building with the new kotlinc

h/t to whoever wrote the sample of https://kotlinlang.org/docs/reference/whatsnew11.html#type-aliases

<!here|@here> at the moment, samples on the

https

version of the site are broken, please use

http

for now and enjoy new live examples. We will fix it shortly http://kotlinlang.org/docs/reference/whatsnew11.html

Anyone know how to translate

kotlin.incremental=true

in Maven?

Why can't I

import kotlin.streams.*

in try.kotlinlang.org?

the embeddable kotlin samples widget is very nice ... is that something open source? i wonder if it's reusable for some of the code examples in my own project

<!here|@here>

kotlinx-coroutines

library version

0.12

for Kotlin 1.1.0 is released. More details in #coroutines channel: https://kotlinlang.slack.com/archives/coroutines/p1488379186003994

Kotlin site seems to be overloaded - at least the samples stoped working 🙈

I'm wondering , how does the Kotlin co-routines actually work on an android device? I know it doesnt use threads , so what does it use? there's an example with 100 thousand co-routines being run simultaneously which is pretty cool , compared to the old threads

@ilya.chernikov I would expect that making incremental compilation possible by an external took (Gradle) was already more effort than doing it internally so I'm a bit confused

Is there any way to create extension functions/properties that apply to a

typealias

but not to the actual type?

I'm not sure I'd even want it yet; I'm just trying to wrap my head around

typealias

usage.
