Crystal lang : method_missing for class object?



Something like this?


class A
module ClassMethods
macro method_missing(call)
% p call %
end
end
extend ClassMethods
end
A.a



Result of the code is Error : undefined method 'a' for A:Class. It seems method_missing doesn't work for class object.


Error : undefined method 'a' for A:Class


method_missing



The reason for the question is that I implemented a class with a current class method to get an instance for current context. For the simplification, I want some like forward_missing_to to replace MyClass.current.xxx with MyClass.xxx, so method_missing is required according forward_missing_to's implementation.


current


forward_missing_to


MyClass.current.xxx


MyClass.xxx


method_missing


forward_missing_to



I also found, delegate works fine for class methods using above way. So actually my pratical problem has been solved, but I'm still interesting with the question : method_missing for class object, is it impossible?


delegate


method_missing





There's no way to do this right now. Also, method_missing is discouraged and I can imagine it being removed in the future.
