Unlike in other languages, Perl's default print function doesn't print newlines by default. This is often desirable, such as in this case:
#!/usr/bin/env perl use strict; use warnings; print("Please enter your name: "); my $name = <STDIN>;
The resulting prompt will have the user type their name on the same line.
Please enter your name: Tousaka Rin
In situations where you want a newline, you use the standard
print("Zettai Ryouiki FTW\n"); print("Tousakaaaaaa!\n");
This was the subject of ridicule from my Ruby development friends in the past, so in 2010 I presented a function that did the same thing. Recent Perl versions have an even shorter function name, with the say command. The following will print the same as the above:
say("Zettai Ryouiki FTW"); say("Tousakaaaaaaa!")
You can use this in your scripts today by requiring at least Perl 5.10, or explicitly enabling the feature:
use 5.010; use feature qw(say);
Done, and done.
