Re: My 'perldar' tells me there is a 'better' solution for this list operation
in thread My 'perldar' tells me there is a 'better' solution for this list operation
it seems a couple of the responses used qw(Field1 Field2 Field3) as opposed to ("Field1","Field2","Field3"). What's the difference?
Short answer, there is no difference :).
Long answer, see perlop.
Evaluates to a list of the words extracted out of
STRING, using embedded whitespace as the word
delimiters. It can be understood as being roughly
split(' ', q/STRING/);
the difference being that it generates a real list
at compile time. So this expression:
qw(foo bar baz)
is semantically equivalent to the list:
'foo', 'bar', 'baz'
Some frequently seen examples:
use POSIX qw( setlocale localeconv )
@EXPORT = qw( foo bar baz );
