Dear Perl Monks,

I just tried to make a simple logger package, having a compilation error with its ver.1 as attached below.

error message

Bareword found where operator expected at /home/tatsu/Perl/MyLog/MyLog
+.pm line 36, near "} encode"
    (Missing operator before encode?)
syntax error at /home/tatsu/Perl/MyLog/MyLog.pm line 36, near "} encod
+e"
Compilation failed in require at logtest.pl line 6.
BEGIN failed--compilation aborted at logtest.pl line 6.

MyLog.pm (ver.1)

use utf8;
use Time::Piece;
use Carp 'croak';
use Encode 'encode';

sub new {
  my $class = shift;
  my $self = {};
  bless $self, $class;
  my $timesig = localtime->strftime("%y%m%d%H%M%S");
  my $logfile = $timesig . '.log';
  if (-f $logfile) {
    croak "log file ${logfile} already exists.: $!";
  }
  open my $fh, '>>', $logfile
    or croak "can't open log file ${logfile}.: $!";
  $self->{fh} = $fh;
  return $self;
}

sub DESTROY {
  my $self = shift;
  close $self->{fh};
}

sub log {
  my $self = shift;
  my $timesig = localtime->strftime("%y%m%d%H%M%S");
#  my $fh = $self->{fh};
  foreach my $msg (@_) {
    print $self->{fh} encode('utf8', $timesig . ': ' . $msg . "\n");
#    print $fh encode('utf8', $timesig . ': ' . $msg . "\n");
  }
}

When a local var $fh was used for the file handle with its print command in the log subroutine (ver.2), however, no error occurred and everything worked as expected. It appears that the error occurs with the 'print $self->{fh}' part, but I am not sure how it comes to the error message 'Bareword found where operator expected...'.

Any advice would be much appreciated.

Sincerely,

MyLog.pm (ver.2, log subroutine only)

sub log {
  my $self = shift;
  my $timesig = localtime->strftime("%y%m%d%H%M%S");
  my $fh = $self->{fh};
  foreach my $msg (@_) {
#    print $self->{fh} encode('utf8', $timesig . ': ' . $msg . "\n");
    print $fh encode('utf8', $timesig . ': ' . $msg . "\n");
  }
}

$mylog->log();
$mylog->log('');
$mylog->log('a', 'b');
