can anyone point me to how to use the Deprecated annotation ReplaceWith when the argument is a receiver function type?

@Deprecated
fun factory(initializer: Builder.() -> Unit): Type = Builder().apply(initializer).build()

[Justin Tullgren]

it keeps bringing in the deprecated builder even when i have added the imports argument to Deprecated

Could you please show an example of what you want the users to use instead of the function?

[Justin Tullgren]

I really just want to do a package move, so same name, args, return, etc

[Justin Tullgren]

same thing with extension functions too, i just want them to move to a different package

[Justin Tullgren]

public fun URI.modified(): URI = URI(this.toString() + "/example")

[Justin Tullgren]

fun main() {
// stays the same but the import should change
val modified = URI("<example://ex>").modified()
}

Oh sorry I missed your messages, for the extension function you can use this in the replacement string:

package com.example.somepackage

@Deprecated(
    message = "",
    replaceWith = ReplaceWith("this.modified()", imports = ["com.example.otherpackage.modified"]),
)
fun URI.modified(): URI = URI(this.toString() + "/example")

And for the initial function you can use:

@Deprecated(
    message = "",
    replaceWith = ReplaceWith("factory(initializer)", imports = ["com.example.otherpackage.factory"]),
)
fun factory(initializer: Builder.() -> Unit): MyType = Builder().apply(initializer).build()

All of this is of course assuming the same function exists in another package

[Justin Tullgren]

awesome thank you! i'll try on monday and let you know how it goes!

[Justin Tullgren]

this doesn't work if anyone checks this thread FYI

[Joffrey]

So FYI the ReplaceWith in this case does work, but it transforms the lambda into an anonymous function. Not very beautiful, but at least the code is correct.
