Your keyedFunctions map should have the type Map<String, CalcContext.() -> Unit>. Might be helpful to define a typealias for that function type.

Thanks Zach. Problem is though that Receiver needs to be generic. I tried making it generic and it compiles, but this causes another problem for me as in the actual code that uses the DSL now can't compile.

[Twferrell]

Reason being is because the contexts can have different method & properties exposed on them.

[Twferrell]

In other words. I can do this...

But then in my DSL code, it can't compile because it doesn't like those generic receivers (e.g. "T"). Because T (e.g. Context) doesn't really share any common methods & properties.

[Twferrell]

Basically, I'm trying to see if there's a way just to treat this as a function reference without compiler having to deal with binding it to a receiver when I store the function reference in the map.

Not sure I understand - I can't see in your initial code screenshot because the error popup is covering it, but what's the code for the validation method?

[Zach Klippenstein (he/him) [MOD]]

Oh I think I get it. So your map value type needs to be generic (Any.() -> Unit), and then you need to cast your callback arguments to that type when storing them in the map. Does that work?

[Twferrell]

I think I tried that as well

[Twferrell]

I might need to just rethink what I'm doing. 🙂

[Twferrell]

I'm probably in a bit of a tangle now.

[Twferrell]

Zach. The Any worked.

[Twferrell]

Thaks man!

[Twferrell]

I just had to clean up few other things that was causing another problem.
