A simpler version that does not clear the screen:
constant @t = < ⡎⢉⢵ ⠀⢺⠀ ⠊⠉⡱ ⠊⣉⡱ ⢀⠔⡇ ⣏⣉⡉ ⣎⣉⡁ ⠊⢉⠝ ⢎⣉⡱ ⡎⠉⢱ ⠀⠶⠀>;
constant @b = < ⢗⣁⡸ ⢀⣸⣀ ⣔⣉⣀ ⢄⣀⡸ ⠉⠉⡏ ⢄⣀⡸ ⢇⣀⡸ ⢰⠁⠀ ⢇⣀⡸ ⢈⣉⡹ ⠀⠶⠀>;
signal(SIGINT).tap: { print "\e[?25h\n"; exit }
print "\e7\e[?25l"; # saves cursor position, make it invisible
loop {
my @x = DateTime.now.Str.substr(11,8).ords X- ord('0');
put ~.[@x] for @t, @b;
sleep 1;
print "\e8"; # restores cursor position
}
Finally a more minimalist version that shows three progress bars (hours, minutes, seconds):
print "\e7";
loop {
my $time = DateTime.now;
put '#' x $_ ~ '.' x (24 - $_) given $time.hour.round;
put '#' x $_ ~ '.' x (60 - $_) given $time.minute.round;
put '#' x $_ ~ '.' x (60 - $_) given $time.second.round;
sleep 1;
print "\e8";
}
END put "\n";
