    @jrenner I have a ray tracer written in Kotlin too but github.com seems to be down right now

    it's the DNS DDOS

    yeah it looked like a DNS problem. Didn’t know about the DDOS

    I have a ray tracer but it’s not in Kotlin, would have made some of the math more readable.

    if you use opendns (208.67.222.222) it seems to fix the issue

    What are valid use cases for the 
    WARNING
    , 
    ERROR
    and 
    HIDDEN
    deprecation levels? For example, what is the difference between just removing a method and marking it as 
    ERROR
    or 
    HIDDEN
    ?

    marking it prevents its use from Kotlin side but only shows as deprecated from Java side

    That makes sense

    @nhaarman there is a big difference actually. With 
    ERROR
    you can provide particular error message and replacement expression. With 
    HIDDEN
    you can't use the declaration but it is existing in the bytecode so already existing compiled code will work so it is useful for binary compatibility

    as far as i remember, there's no way to recommend outright deletion

    that was my biggest gripe back when i used it

    ReplaceWith("TODO(\"Remove me\")")
    ? 🙂

    would be nice to see a constant for deletion on the annotation? 
    replaceWith = RECOMMEND_DELETE
    or something

    10/21/2016, 8:05 PM
    You definitely have to raise an issue about that

    what if your replacement method has a different order that it accepts arguments in or something? Is there a way to specify that the replacement should reorder the arguments or anything like that?
  • c

    cy

    10/21/2016, 8:06 PM
    what do you mean by "order" ?
  • c

    cy

    10/21/2016, 8:06 PM
    arguments order or method calls order?
  • c

    cy

    10/21/2016, 8:11 PM
    you can refer to an arguments by parameter names and this receiver in an expression

    Copy code
    @Deprecated("Use new API instead", ReplaceWith("someNewAPI(name, size)"), DeprecationLevel.ERROR)
fun someOldAPI(size: Int, name: String): String = TODO("something complicated")

fun someNewAPI(name: String, size: Int): String = TODO("new implementation")

fun someUsage() {
    someOldAPI(1 + 1, "") // -> someNewAPI("", 1 + 1)
}

    Seems like Kotlin doesn't wanna let me call a protected method of a base class on another object.

    Here in Kotlin I would get "Cannot access 'testSomething': it is protected in 'A'", is that expected?
