Re^4: Replacing single quotes to two single quotes inside map

That's because of the || ''. If the substitution returns false, i.e. there's no smart quote to substitute, you replace this return value that goes nowhere ("void context") by an empty string. You probably meant to add it into the assignment instead?

map { (my $dx = $data->{ $_ } || '') =~ s/’/'/g; $dx } @allparms

But that would replace 0's with empty strings. Use // to replace only undefs.

Update:

map { (my $dx = $data->{ $_ } // '') =~ s/’/'/g; $dx } @allparms

You mean that this way: `map { (my $dx = $data->{ $_ } \|\| '') =~ s/’/'/g; $dx } @allparms` [download] Will not replace 0s with empty string, correct?	[reply] [d/l]
