I’ve just noticed that Kotlin Playground and, as a result, also Kotlin snippets in the docs and on kotlinlang.org, don’t highlight syntax for expressions inside the strings. It looks a bit weird, as if it was a regular string, especially when you’re used to IntelliJ being aware of the expressions. I see that the editor component used there is https://codemirror.net/, and apparently for JS it has the expressions syntax highlighting implemented

Yeah, also always stumbled upon that.
The project to report that to on Kotlin side is https://github.com/JetBrains/kotlin-playground.
But the main issue is probably to be reported to the Codemirror project I guess, or where the Kotlin mode is maintained.

Hi there,
Sad, but that is not supported by Playground yet.
We have a task in our backlog to implement, but it requires an update Codemirror beforehand since the used version is outdated.
We plan this work in the mid-term (within three months).
I created a task in KT project - KT-61021

Where is the Kotlin mode coming from? I don't see it in the Codemirror repo

As if Kotlin is too much c-like 😄

[Piotr Krzemiński]

it has braces… like the majority of languages 😄

[Piotr Krzemiński]

fair enough, Java’s syntax is inspired by C++, C++ came from C, Kotlin is “Java++“. Here you go

Indeed playground seems to set data-target-platform to java which then ends up also in the c-like mode
