Hi all, a short `undef` logic question: I wrote a statement like ( Expr1 || regexp('strfoo',MyAdd) ) != trueUnfortunately, I had assumed, that the regexp macro should always resolve to
( Expr1 || true/false ) != truebut Kruno pointed out, that in case the ad is undef the macro is not defined as well - which would result in
undef != true ðSo, one question would be, if there is a `?`-like operator for a boolean non-equal comparison, that resolves in false when compared to undef?
To catch undef cases, we are going now for ( Expr1 || regexp('strfoo',MyAdd) ? : "" ) ) != true but we are not sure, if `?` as operator actually catches undefs here? Cheers, Thomas
