Is there a easy way to "pretty print" toString of a dataclass (indentations, new lines etc) ?

I think the only way is to override the toString function for the data class.

I think you could potentially create an extension function on

Any

that does pretty printing if it's standard across all your data classes

@Steven McLaughlin But this will affect not only data classes. So for other developers this maybe a surprise.

Sure, I'd probably call it like

toPrettyString()

or something explicit.

@ursus Don't know your use case, but a serialization library like kotlinx.serialization or Jackson might be a consideration instead?

@robin yea using json was my plan B
