Would be fantastic to have a KotlinX Cinterop ( https://kotlinlang.org/api/latest/jvm/stdlib/kotlinx.cinterop/ ) Safari type video series on the Kotlin YouTube channel ( https://www.youtube.com/channel/UCP7uiEZIqci43m22KDl0sNw ), just like the Kotlin Standard library Safari series ( ).

Hi, is there a channel dedicated to Aspect orientated programming with Kotlin

Hey all, we made a new 0.6.0 release of our static analysis and code-fixer tool. Release includes the logic for auto-simplification of Boolean conditions with Boolean algebra (haven’t seen any Kotlin analysers doing this stuff) : https://github.com/cqfn/diKTat Check it out it can be very useful for your projects! 🥳 Stars, issues and contribution is appreciated 😘

Hey. Is there any simple way to list all the properties in a class excluding the ones with an explicit getter? E.g.

data class Person(val name: String, val age: Int) {
    val signature: String get() = "$name - $age"
}

val allProps = Person::class.declaredMemberPropertiesExcludingGetters // xD
  // returns [Person::name, Person::age]

Has anyone else run into this problem: we are trying to upgrade to kotlin 1.5.10, and we are using gradle and spring boot stack. However, our gitlab CI fails every time on the gemnasium-maven-dependency-scanning job. It doesn’t provide any message it just fails with

exit status 1

kotlinx.serialization 1.2 のリリース: JSON 高速処理、値クラスのサポート、ドキュメントの見直しなど 先日、kotlinx.serialization 1.2 がリリースされました！ 当社のマルチプラットフォーム向けシリアル化ライブラリの最新バージョンにはいくつかの改善点が盛り込まれています。以下、その概要を紹介します。 JSON のシリアル化がこれまでで最速に。 バージョン 1.2 では、JSON を型安全な Kotlin オブジェクトに解釈し、Kotlin オブジェクトをテキストとして表示する処理を過去のバージョンよりも最大で 2 倍も速く処理できるようになりました。 Kotlin 1.5 で追加された型システムのサポート。 Kotlin の他のクラス同様に、値クラス（value class）・符号なしの数値を JSON に変換し、また元に戻すということができるようになりました。 新しくなった API ドキュメント を使用すれば、kotlinx.serialization が提供するすべての機能を簡単に見つけられます。 バージョン 1.2 には、JSON フィールドの代替名に対するサポートが新しく盛り込まれているほか、それにより、Kotlin クラスから自動的に...
