Hmm, interesting! Nothing for non-android yet?

This is just an IDE inspection, so maybe make sense to report it to Kotlin team, maybe make sense include such annotation to Kotlin stdlib, jetbrains annotations or as a separate artefact for Java compatibility

Looks to be tightly coupled with their build tooling

ideomatically?

Realistically speaking, how expensive is

this::foo.getDelegate()

reflection call on a big scale? Let's say it's being called for almost every field in every UI class. For the context, I'd want to observe property changes as an Observable stream, something like this:

fun <T : Any> KMutableProperty0<T>.observe(): Observable<T> = (getDelegate() as MyDelegate<T>).observe()

Any ideas?

on a

MutableMap::replaceAll

, I get

Symbol is declared in module 'java.base' which does not export package 'kotlin.collections'

file is marked as red, but it compiles fine

I’m getting a kind of horrific error trying to compile a Kotlin project that depends on a a Scala jar:

e: org.jetbrains.kotlin.util.KotlinFrontEndException: Exception while analyzing expression at (42,31) in …

Caused by: java.lang.IllegalStateException: No parameter with index 0-0 (name=reverser$module$1 access=16) in method scala.collection.TraversableOnce.reverser$2

The expression in question is

this.args().tail()

Is there some guide to get started on pulling info from some low level apis such as wireless information, battery information, etc? I know in linux its easy by running some commands and filtering outputs, but its a mess in platforms like windows where we need to write some sort of bindings in like jni, but I still don't know much about JNI and want some guides to work. And is it possible to interact them (low-level api) with help of Kotlin/Native to write bindings for Kotlin/JVM instead of writing in direct C++?

Accidental override, but if I add

override

, it "overrides nothing"?

So it is a bug and has been reported! https://youtrack.jetbrains.com/issue/KT-12993 4 years with no resolution! Why, just why?

Yep! And I don't think compiling to native would be any faster! In fact, that could be slower than compiling to java and then starting the JVM... but I'm not sure...

I’m happy to file a bug, but just want to make sure this isn’t something people already know about or whether there’s an easy workaround.

Hey Is there any analysis of kotlin source as a code? I’m interested in understanding where does the part of kotlin-common in kotlin sources, how it becomes extended by kotlin-jvm, how kotlin-common become transpiled to llvm IR in terms of kotlin-native, etc.

How do I run a custom Kotlin script (separate file) from Gradle?

Hi I'm trying to instantiate an

inner class

reflectively using Kotlin-reflection library it's not hard except that I need to pass an instance of the parent class to the child class constructor. Is there any function/way to get the

KType

of parent class (without using it's name and

Class.forName()

)? here is an example of what I'm trying to achieve:

class Parent {

    inner class Child()
}

fun main() {
    val childType: KType = typeOf<Parent.Child>()

    val parentType = childType.getParent()
}

Is it possible to create an

annotation class DynamicAnnotation(val type: String)

that somehow applies one of two existing annotations based on the passed type parameter? Specifically, I want to do something like this:

val annotation = "Serializable" // or, "JsExport"

@DynamicAnnotation(annotation)
data class User(val id: String)

...such that when the

annotation

string is set to

"JsExport"

, it will generate:

@JsExport data class User(val id: String)

And when it's set to

"Serializable"

, it will generate:

@Serializable data class User(val id: String)

This is to deal with a known bug in Kotlin 1.4-M2 and kotlinx.serialization (you can't have classes annotated with Serializable and JsExport for some reason). Any ideas?

damn, never guessed I would encounter this haha.

I have created this little project where I try to read Kotlin code by using the library org.jetbrains.kotlinkotlin compiler embeddable1.3.72. I got the code example from here but unfortunate, when I execute main() in App.kt I get this error. Any ideas? Exception in thread "main" java.lang.IllegalStateException: LOGGING: Loading modules: [java.se, jdk.accessibility, jdk.attach, jdk.compiler, jdk.dynalink, jdk.httpserver, jdk.jartool, jdk.javadoc, jdk.jconsole, jdk.jdi, jdk.jfr, jdk.jshell, jdk.jsobject, jdk.management, jdk.management.jfr, jdk.net, jdk.scripting.nashorn, jdk.sctp, jdk.security.auth, jdk.security.jgss, jdk.unsupported, jdk.unsupported.desktop, jdk.xml.dom, java.base, java.compiler, java.datatransfer, java.desktop, java.xml, java.instrument, java.logging, java.management, java.management.rmi, java.rmi, java.naming, java.net.http, java.prefs, java.scripting, java.security.jgss, java.security.sasl, java.sql, java.transaction.xa, java.sql.rowset, java.xml.crypto, jdk.internal.jvmstat, jdk.management.agent, jdk.jdwp.agent, jdk.internal.ed, jdk.internal.le, jdk.internal.opt] (no MessageCollector configured) at org.jetbrains.kotlin.cli.jvm.compiler.ClasspathRootsResolver.report(ClasspathRootsResolver.kt:312) at org.jetbrains.kotlin.cli.jvm.compiler.ClasspathRootsResolver.report$default(ClasspathRootsResolver.kt:310) at org.jetbrains.kotlin.cli.jvm.compiler.ClasspathRootsResolver.addModularRoots(ClasspathRootsResolver.kt:253) at org.jetbrains.kotlin.cli.jvm.compiler.ClasspathRootsResolver.computeRoots(ClasspathRootsResolver.kt:123) at org.jetbrains.kotlin.cli.jvm.compiler.ClasspathRootsResolver.convertClasspathRoots(ClasspathRootsResolver.kt:79) at org.jetbrains.kotlin.cli.jvm.compiler.KotlinCoreEnvironment.<init>(KotlinCoreEnvironment.kt:219) at org.jetbrains.kotlin.cli.jvm.compiler.KotlinCoreEnvironment.<init>(KotlinCoreEnvironment.kt:115) at org.jetbrains.kotlin.cli.jvm.compiler.KotlinCoreEnvironment$Companion.createForProduction(KotlinCoreEnvironment.kt:427) at polylith.kotlin.Lib$project$2.invoke(App.kt:30) at polylith.kotlin.Lib$project$2.invoke(App.kt:12) at kotlin.SynchronizedLazyImpl.getValue(LazyJVM.kt:74) at polylith.kotlin.Lib.getProject(App.kt) at polylith.kotlin.Lib.createKtFile(App.kt:38) at polylith.kotlin.Lib.main(App.kt:24)

I’m looking for people that are interested in working on the open source project (polylith-kotlin) that I mentioned above. Is there any good place to go in the Kotlin community for that?
