Anyone knows if there is a way (e.g., a plugin) to generate a copy function without hashCode and toString? I don't want to use data classes in certain environments.

There is poko but it also generates hashCode and toString https://github.com/drewhamilton/Poko

You could fork it and remove the hashCode/toString implementation though.

[Edoardo Luppi]

Ah wait, but Poko does the opposite, it generates everything but not copy.

[hfhbd]

Oh, yeah 🤦🏻‍♂️

You could do

abstract class CopyOnly {
  final override fun equals(other: Any?): Boolean = super.equals(other)
  final override fun hashCode(): Int = super.hashCode()
  final override fun toString(): String = super.toString()
}

data class MyData(
  val asdf: Int,
) : CopyOnly()

That would also leave you with the componentN functions though

@Adam S works only on data classes unfortunately.

Same for the maintained Kopy alternative.
