的 print 如何在默认情况下添加一个新行？

Question

In Perl most of my print statements take the form

print "hello." . "\n";

Is there a nice way to avoid keeping all the pesky "\n"s lying around?

I know I could make a new function such as myprint that automatically appends \n, but it would be nice if I could override the existing print.

Answer 1

Perl 6 has the say function that automatically appends \n.

You can also use say in Perl 5.10 or 5.12 if you add

use feature qw(say);

to the beginning of your program. Or you can use Modern::Perl to get this and other features.

See perldoc feature for more details.
