another question where i am not even sure where to begin searching.. is there a annotation that lets the user know that something else might be cleaner and replace code
that is less severe than @Deprecated
usecase is a DSL

[jcechace]

Would use @Deprecated on warning level

[jcechace]

https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-deprecation-level/index.html

[Nikky]

cool, thanks, setting the level actually helps me in a few more places

[Sam]

Not to mention, @Deprecated could also be used with @ReplaceWith as well

https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-replace-with/index.html

[Nikky]

i have no idea how to use ReplaceWith though..
i wand to do this
id(SomeExpression) -> + someExpression

and ideally in the case that the lambda is specified do
id(someExpression) { moreExpressions } -> add(someExpression) { moreExpressions }

[Nikky]

is there some kind of printf like syntax that can be used in ReplaceWith that i do not know about ?

[Sam]

@Nikky something like this helps IDE do the actual replacement

@Deprecated("Use fooBar()",
        replaceWith = ReplaceWith("fooBar()"))
fun fooBar( value : Int ): Unit = println( "old one" )

fun fooBar() = println( "new one" )
fun main( argv : Array<String> ) {
    fooBar(1)
}

[Nikky]

yeah so far i understand but that is plainly said.. useless without the ability to automatically refactor some parts of the expression.. what if you did not want to loose the argument ?
in your example it just gets dropped
