[Rpm-ecosystem] Triple operator for conditional shortcut - choosing the best notation

[Pavlina Moravcova Varekova]

Hi,
I plan to implement "Triple operator for conditional shortcut".
(https://github.com/rpm-software-management/rpm/issues/115.)
There are several possibilities that can be used:

%{?{condition}:true:false} and %{!?{condition}:false:true}

or

%{?{condition}?true:false} and %{!?{condition}?false:true}

or

%{?:condition:true:false}  and %{?!:condition:false:true}

>From the implementation point of view they are quite similar, so please does any of the notations look appropriate for you? Which of them do you prefer?

For more details see. https://github.com/rpm-software-management/rpm/issues/115.
