use File::Stamped;
my $fh = File::Stamped->new(pattern => '/var/log/myapp.log.%Y%m%d.txt');
$fh->print("OK\n");

use Log::Minimal;
my $fh = File::Stamped->new(pattern => '/var/log/myapp.log.%Y%m%d.txt');

    my $f = File::Stamped->new(callback => sub {
        my $file_stamped = shift;
        local $_ = $pattern;
        s/!!/$$/ge;
        $_ = POSIX::strftime($_, localtime());
        return $_;
