Somebody please help me uderstand the deal with qq. I have run tests
on all three lines of code below and it turns out that #1 and #3 work
but #2 does not. I am under the impression that qq acts as double
quotes. So why doesn't #2 work isn't it the same as #1? NO COMPRENDE!!!
1. print qq/I said Help me!!.\n/;
2. print I said Help me!!.\n;
3. print I said /Help me!!/.\n;
#1 works, but #2 and #3 do not. I think you meant to use \ instead of
/ in #3.
qq() is double-quoted context, but it is a replacement for physical
double-quotes. By using qq//, it's like / is now your quote.
Just like
he said hi to me
is invalid, so is
qq/he said /hi/ to me/
To get that to work, you'd need to backslash the quoting character:
he said \hi\ to me
qq/he said \/hi\/ to me/
but that should be a sign that you should've chosen a different character.
Using qq(), qq[], qq{}, or qq allows you to nest the quotes:
qq(I think (since I'm ill) I won't go to class today.)
