I'm writing a DSL. It's something like this.

class Scope {
    fun method(block: () -> Unit) {}
}

fun scope(block: Scope.() -> Unit) {}

fun main() {
    scope {
        method {
            method {  } // I want to disallow using the scope inside the method
        }
    }
}

I want to disallow calling method on the

Scope

inside the

method

. I know I can have a dummy receive object and mark the

Scope

and the dummy object

DslMarker

.

@DslMarker
annotation class MyDslMarker

@MyDslMarker
class Scope {
    fun method(block: Context.() -> Unit) {}
}

@MyDslMarker
object Context // Dummy object

fun scope(block: Scope.() -> Unit) {}

fun main() {
    scope {
        method {
            method {  } // Compiler error now
        }
    }
}

Any better solution?

Sounds like you need @DslMarker guess you edited your post to include this already

Can I do it without adding dummy receiver object?

Ah, I think I see the problem. That’s interesting, I’m not sure
