    Reasons not to use 
    @Suppress("NON_PUBLIC_PRIMARY_CONSTRUCTOR_OF_INLINE_CLASS")
    to overcome that restriction in a Kotlin only code?

    hi, why do I have to use @JvmField to make a property compatible with java?
  • b

    Bernhard

    02/02/2019, 8:18 AM
    is it because Kotlin generates incompatible meta data?

    Just want to leave a little thanks: I just found the 'convert parameter to receiver' action and isn't this awesome to have it!

    hey guys! How can I xor Char with some value? ie. I'd like something like: "abcd".map {it .xor(32)}

    (it.toInt() xor 32).toChar()

    ok, I was hoping for less characters 🙂

    is there a way to know if my inline function has been called from java

    actually in general is there a way to know if my function has been called from java

    I'm trying to get clever with 
    @JvmOverloads

    but then I get these platform clash errors

    Get a stacktrace and check the filename extension of the code one level up. But I'd argue this is a bad idea, functions really shouldn't change behaviour depending the caller.

    I'm trying to make an rxjava errorhandler that tells you where the subscribe() call was
  • a

    05/07/2019, 11:33 PM
    but don't always want to incur the overhead of 
    new Throwable()
    every time I call subscribe()

    although tbh that's ok most of the time

    so one trick I used was to make the 
    Consumer
    generation function inline, which works great when called from kotlin

    Ah okay, error handling and logging should be fine simple smile. Though the biggest overhead of a throwable is getting the stacktrace, and you'll have to pay that anyway.

    but not so great when called from java
  • a

    05/07/2019, 11:46 PM
    I guess I should just accept the 
    Throwable
    overhead

    I'm just trying something crazy out... the IDE hasn't yelled at me yet, but is it even possible to call to execute a 
    vararg
    of functions sitting in a class parameter?

    Copy code
    class SomeClass(
        vararg functions: (Stringr) -> Unit
) {...}

    how was the syntax to assign and return from a method if a variable is not set + outputting a log?

    Is there an easy way to disable output of metadata annotations in jvm compilations?
