Hi guys. I'm trying to write a DSL. Suppose I have this structure:

class A(val someObject : SomeObjectClass) {

    fun doSomethingWithSomeObject() {
        // TODO do something with someObject
    }
}

How would I achieve something like the following in Kotlin:

coolDSL(someObject) {

    doSomethingWithSomeObject {
        someObject.callSomeMethod()
    }

}

Thanks in advance.

@Denis A, Thanks. As far as I understand, apply() will call appropriate functions on someObject. I would like not call functions, but provide implementations.

You need something like this

fun cooldDsl(
   obj: SomeObjectClass, 
   block: SomeObjectClass.() -> Unit
) {
  block(obj)
}

I think, we can’t change base syntax (of any language), but we can use own codestyle

Just need one more wrapper to have
doSomethingWithSomeObject

If you provide more complete example I can show how to wrap it to dsl
