Topic: Conditional insertion
I would like to insert some expression depending if another expression is empty or not. It could be useful to add such possibility
My case is the following:
If %Ev is not empty, then insert it rounded by dot-parenthesis *.(%Ev).*,
ElseIf %EV is not empty then insert it rounded by dot-squared brackets *.[%EV].*,
Else insert nothing *.*.
This could be something like:
%Ev?(x,y) => if %Ev is empty or zero, then insert x else insert y
or more sophisticated:
%Ev=a?(x,y) => with "=" is an comparison operator (= or ==, <=, <> ou !=,...)
or another syntax.
