是否可以使用Term::TermKey以类似的方式获取光标位置Term::ReadKey可以做到这一点:
#!/usr/bin/env perl
use warnings;
use 5.12.0;
use Term::ReadKey;
ReadMode 4;
system( 'clear' ) == 0 or die $?;
print "Hello world\n" x 4;
print "go to column 21 -> |";
print "\e[6n";
my ( $x, $y ) = getch();
say "Col: $x - Row: $y";
ReadMode 0;
sub getch {
my $c = ReadKey 0;
if ( $c eq "\e" ) {
my $c = ReadKey 0.10;
if ( $c eq '[' ) {
my $c = ReadKey 0;
if ( $c =~ /\A\d/ ) {
my $c1 = ReadKey 0;
if ( $c1 ne '~' ) {
my $y = 0 + $c;
while ( 1 ) {
last if $c1 eq ';';
$y = 10 * $y + $c1;
$c1 = ReadKey 0;
}
my $x = 0;
while ( 1 ) {
$c1 = ReadKey 0;
last if $c1 eq 'R';
$x = 10 * $x + $c1;
}
return $x, $y;
}
}
}
}
}
