forgive this post, but if you would like to have bitwise operatos, please vote this issue: https://youtrack.jetbrains.com/issue/KT-1440

[bamdmux]

Seeing the example you posted, why you dont consider writing a small class to handle those flags?

[bamdmux]

class IntFlag(var value: Int = 0) {
    fun set(f: FLAGS) { value = value or f.value }
    fun unset(f: FLAGS) { value = value and f.value.inv() }

    fun flagged() = FLAGS.values().filter { (value and it.value) != 0 }
}

enum class FLAGS(val value: Int) {
    FIRST(1), SECOND(2), THIRD(4), FOURTH(8) //Use whatever tags you need
}

Is there an issue where I can vote AGAINST the bitwise operators? I come from C++, where it is a norm to pack the code with unreadable shifts and masks. It is not worth it.

@voddan Cant you vote down on youtrack? Its only up?

because of instantiation

[elect]

I'd need to create a new instance into every sub-function that is called

[elect]

loc would explode, and the design would get away from the cpp version

[bamdmux]

I dont know your performance constraints, but if you want to avoid instantiation you could use a singleton

[bamdmux]

object FlagHelper {
    val flag = IntFlag()
    fun apply_flags(init: Int = 0, actions: IntFlag.() -> Unit) = with(flag) {
        flag.value = init
        actions()
        value
    }
}

immediate gui for 3d realtime graphic

that'd add too much verbosity

[elect]

I'm using flags a lot, example https://github.com/kotlin-graphics/imgui/blob/bd3748222dd62bc221e935582160cca2dc0ba54c/src/main/kotlin/imgui/imgui/widgetsColorEditorPicker.kt#L410-L422

atm I am bringing some code down thanks to import renaming

[elect]

(importing the whole enum isnt an option for me)

[bamdmux]

Ok
