ah, nevermind, I think I just figured it out. I was on the right track earlier but had the syntax wrong

if anyone else cares to know the solution:

.sortedWith(
    compareBy(
        { it is SomeType },
        { (it as? SomeOtherType)?.stringField }
    )
)

I was wondering.. Is allowing Kotlin to compile to more modern JVM bytecode versions a priority right now?

https://twitter.com/kotlin/status/1219567890812362752 The Kotlin/JS Gradle plugin ships with webpack-dev-server. Together with Gradle continuous builds (using the "-t" run configuration argument in IntelliJ IDEA or by invoking ./gradlew -t run), you can have your page reload automatically whenever you change your code. #KotlinTips https://t.co/Xzx5744G9Q Twitter

Hi 🙂

Greetings 🙂

The above does not work for me

How can we unit test Realm??

I ask this because the latest update on "Getting started with gradle" is from 2016

I needed a ser. deser. for handling

Clazz<T>

like things with reified it was too easy. Is there anything problematic about this?

class Serde {
    
    var mapper = jacksonObjectMapper()
    
    fun <R>serialize(instance: R): ByteArray {
        return mapper.writeValueAsBytes(instance)
    }

    inline fun <reified R>deserialize(arr: ByteArray): R {
        return mapper.readValue<R>(arr)
    }
}

Hi simple smile

@iex you could use a forEach which takes a predicate. You can use an annotation (@lit) to return to the caller. https://kotlinlang.org/docs/reference/returns.html

Hi, have someone tried to do something like file templates in kotlin. I need to replace variables in YAML file and get the post processed YAML. What is the best way to do this?

the compiler, that is

Is there a better way to write this (it's to convert a

JsonObject

to a

Map<String, String>

?

Gson().fromJson(json, object : TypeToken<Map<String, Any>>() {}.type)

Has anyone seen the following warning? Trying to build a test app on iOS (that imports a <MyLibraryName>.framework).

https://twitter.com/kotlin/status/1220383288109535232 Use ‘it’ only in the simplest scenarios, when its type is clear from the context. Otherwise, introduce an explicit lambda parameter or use member references. It’s especially important for call chains where the lambda parameter type changes from one call to the next #KotlinTips https://t.co/Z8ZFvfbAv7 Twitter

I have a mixed Kotlin and Java codebase and a singleton in Kotlin with its methods called from Java. The singleton

Manager

delegates all calls to an implementation of an interface

Service

(there are multiple possible implementations of

Service

,

Manager

picks one at startup). Right now, the code does

object Manager { val delegate = pickImpl(); @JvmStatic fun foo() = delegate.foo(); @JvmStatic fun bar(a: Int) = delegate.bar(a); ... }

and the Java code calls

Manager.foo()

. This could be simplified to

object Manager : Service by pickImpl()

but then the Java code has to be changed to call

Manager.INSTANCE.foo()

. Is there a way to use delegation but retain the

JVMStatic

for the Java code?

Guys, Is there a way to parse YAML in some default structures, not in predefined objects (DTO)

Is there a good channel here to chat about Jetbrains UAST parser? and more specifically around how it works together with kotlin sources.

Not specifically for UAST but #compiler #detekt #kontributors could be somehow helpful

Anybody else have problems getting Operation org.gradle.tooling.internal.provider.events.DefaultTestDescriptor@2688b018 already available. error messages? I have a multiplatform jvm/js project and it's building just fine, but sometimes I get that error in the IntelliJ build pane despite no such error showing in the Gradle logs. I don't really know how to report this as a bug because there's no stack trace.

Nevermind, I made a silly mistake. (Wrong function name called)

Hey guys. Does anybody know how to apply gradle plugin by class in

init.gradle.kts

with Kotlin DSL? For example, this does not work:

initscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.sonarsource.scanner.gradle:sonarqube-gradle-plugin:2.8")
    }
}

allprojects {
    pluginManager.apply(org.sonarqube.gradle.SonarQubePlugin)
}

Reason:

Line 11:     pluginManager.apply(org.sonarqube.gradle.SonarQubePlugin)
                                                        ^ Classifier 'SonarQubePlugin' does not have a companion object, and thus must be initialized here

I just forgot to add

::class

... Sorry about that.

Naming is hard. Need help:

class EventRepository(val bikeEventHelper: BikeEventHelper, val carEventHelper: CarEventHelper){
  fun carEventHelper() = carEventHelper
  fun bikeEventHelper() = bikeEventHelper
}

Looking for suggestions on naming the

EventRepository

class.

im unable to integrate intellijIDE and kotlin 😢
