Source code: stringers Module: P205


You can write strings in double or single quotes in Perl.

In single quotes, they're taken as literal strings so that
any character you include becomes part of the string. In
double quotes, though, some elements are interpretted ...
        \ is the "escape" for a following special char / sequence
        $ indicates that a scalar is to be included
        @ indicates that a list is to be included

You can change the delimiter if you like to another special
character rather that " and ' using qq and q followed by that
special character - great if you want double quotes within a
double quoted string, and essential is you want a single quote
in a single quoted string.

And you can even use what's called a "here document" to set a
whole line of text up as a delimiter - there's an example below.


$him = "Phil";
$her = 'Phoebe';

$story = qq^"Don't wash the dog" said $him to $her\n^;
print $story,"\n";

$story = q%"Don't wash the dog" said $him to $her\n%;
print $story,"\n";

$story = <<"DONE"
"Don't wash the dog" said $him to $her as $her hung
the washing on the line. "I washed Rover yesterday"
$him continued "and he's NOT happy with me ..."

print $story;


Sample output

Dorothy-2:j10p grahamellis$ perl stringers
"Don't wash the dog" said Phil to Phoebe

"Don't wash the dog" said $him to $her\n
"Don't wash the dog" said Phil to Phoebe as Phoebe hung
the washing on the line. "I washed Rover yesterday"
Phil continued "and he's NOT happy with me ..."
Dorothy-2:j10p grahamellis$
