Hello everyone, I am trying to generate Multiplatform code at build time. can KSP do this? or do I need to dive into Compiler Plugins?

[Dominaezzz]

Depends on what inputs you need for code generation.

[andylamax]

I am trying to generate something like this

class GeneratedAction {
  fun execute(param: Param)
}

From a source code like this

annotation class Generate

class Param(val id: Int, val name: String)

@Generated
open class GenericAction

class Action(val input: Param) : GenericAction

Just generating new code can be done with KSP. It's basically like Java APT, but with a Kotlin-API and supporting kotlin multiplatform (afaik)

[diesieben07]

But you cannot alter the code (just like with Java APT)

[andylamax]

Music to my ears. Thanks @diesieben07 will look deeper onto KSP then. Coz those Compiler Plugins still scare me

[diesieben07]

well, KSP really is a compiler plugin itself - it just gives you a nice (and stable) API

[andylamax]

Then it is even a better stepping stone

[diesieben07]

You of course don't interact with the Kotlin compiler directly, KSP does that for you. But your code runs as part of the kotlin compiler

Ksp is still jvm-only

Mpp support planned for kotlin 1.5.20

[diesieben07]

Thanks for clarifying, I wasn't sure on that part

[diesieben07]

Do you have any links on that @Big Chungus? I only found this: https://github.com/google/ksp/issues/60 which is just for making KSP work on the JVM part of a MPP project (not actual "common code").

It's come up on Slack a couple times, for example here: https://kotlinlang.slack.com/archives/C013BA8EQSE/p1621877970017600
