I just updated to

1.3.0-rc-152

and now I get

Could not find org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.0-rc-152.

.. anybody else?

feels like i saw this question often enough that i should write a tutorial about how to use pluginManagement with kotlin eap or someone who already got medium and would not mind writing some fancy words around the basic gradle code ? not like its complicated, it just feels like most people do not even know that you can instruct gradle how to resolve plgins

How often are RCs pushed to bintray https://dl.bintray.com/kotlin/kotlin-eap? I see on github the most recent version of kotlin is 1.3.0-rc-168 but on bintrray, the highest RC is 1.3.0-rc-146.

I have a question about Kotlin 1.3 coroutines. When I took on one of suspend function that return String by ByteCode Viewer, I noticed <undefined type>

Is there any way to make a function such as

handleBox

typecheck without unsafe casting?

Are there branding guidelines for Kotlin programming language? I would like to see

kt

files with Kotlin icon and not as a standard text file icon in Linux/KDE.

When you create a java class (with IDEA), and provide the name

com.ab.cd.ef

.) it creates the package

<http://com.ab.cd|com.ab.cd>

and puts the class

ef

inside it. Doing the same with Kotlin, it creates a file called

com.ab.cd.ef

. Whyyyy 😞

Hi. I’m using a third-party Kotlin library compiled for JVM 1.6. My application is targeting JVM 1.8. When I try to compile my code that calls an inline higher-order function in the library, I get the following compilation error:

Error:(17, 5) Kotlin: Cannot inline bytecode built with JVM target 1.8 into bytecode that is being built with JVM target 1.6. Please specify proper '-jvm-target' option

What’s the solution to this?

📣 I’ve created #webassembly for topics specific to this platform.

So I hav a List<String> of values like "net" and "com". And I have a function where I have to iterate over this list and return a boolean whenever the value of the list matches a string. How do I do this? perhaps onEach can help, but idk how to implement that.

I saw the list, but didn't find the reasoning to leave them out, whether it was a concious design decision or just something they hadn't come around to

Is there some easy way to list the public members (classes, funs, vals) of a kotlin module ?

I wanted to see how a function similar to this

fromJson

function behaves with a generic type and found this. Can anybody explain why that instance check is sometimes true and other times false? 🤔

Who here has actually used === on their code? Why did you use it? I personally have never needed to

It works, but

Void

? Is there something more Kotlinish? Or this is because I’m using

RxJava

not

RxKotlin

fun foo(foo1: String) : Boolean {
        var hasit = false
        for(fooS in fooList) {
            if(fooS == foo1) {
                hasit = true
                break
            }
            else continue
        }
        return hasit
    }
...
var fooList = listOf<String>(...)

How do i change the above function to use collection functions like forEach or anything else ?

fooList.any { foo1 == it }

?

Will inline classes allow to wrap a pair? would be nice to have named pairs without overhead

you can clear the gradle cache if you want

if we have a base class with a property like:

var parent: MyAbstractClass? = null

how can I override this property in some of the concrete class to have something like:

override var parent: MyConcreteClass? = null

I know that is possible to override properties, but it looks like kotlin do not understand that the MyConcreteClass is a supertype coming from the MyAbstractClass. Is there a way to get around this?

If I have a collection and i want to chain

.filter

only if a certain condition is true, how do I do that?

.apply { if (boolean) filter {} }

does not seem to work

This message was deleted.

So much for staving off that discussion 🙂

is there actually a timeline/roadmap for the 1.3 release?

public interface JavaDup
{
 // public String a ;
  public String getA();//{ return a ; }
  public void setA(String a) ;//{ a=_a;}
}

----- kotlin

import util.JavaDup

class B : JavaDup {
  override var a : String = "hi"
}

Is there a good way to get code coverage for Kotlin with something like JaCoCo? If I just add the source and build dirs, wouldn't it just report false positives due to code generation for e.g. data classes?

I just watched Dave Ford's amazing talk on React Kotlin from last year() and I was wondering how things have progressed since then. Is there a type-safe way to manipulate CSS yet?

is any1 experimenting AS 3.2.1 totally unusable while building a project ?
