The Daily Kotlin

Kotlin 2.1.20-Beta1

This version includes context parameters under the flag -Xcontext-parameters, but there is no IDE support (K2 Mode) in the current stable version of IntelliJ IDEA.


context(userContext: UserContext)
fun testUserInfo() {
    println("Hello, world! I'm ${userContext.user.id}!")
}

Additionally, context receivers still function in 2.1.20-Beta1 (even though I previously wrote that they wouldn’t).

Also:

- Kotlin K2 compiler: new default kapt plugin
- Gradle: support for version 8.11

Context Receivers → Context Parameters migration plan:

Kotlin 2.0.20 – new warning in build introduced: CONTEXT_RECEIVERS_DEPRECATED, with -Werror we have to manually suppress it for each file
Kotlin 2.1.0 – Disable warning globally https://youtrack.jet…
