是否有变量或函数可以告诉我光标的实际位置?
#!/usr/bin/env perl
use warnings;
use 5.012;
use Term::ReadKey;
use Term::Cap;
use POSIX;
my( $col, $row ) = GetTerminalSize();
my $termios = new POSIX::Termios;
$termios->getattr;
my $ospeed = $termios->getospeed;
my $terminal = Tgetent Term::Cap { TERM => undef, OSPEED => $ospeed };
# some movement ...
# at which position (x/y) is the cursor now?
