Sorry, I was thinking about the problem correctly. Try:
#!/usr/bin/perl
use Getopt::Long;
use Log::StdLog;
my %cmd_args = ();
my $cmd_args_ref = \%cmd_args;
GetOptions(
"log-level=s" => \$cmd_args{"log_level"},
);
sub log_format {
my ($date, $pid, $level, @message) = @_;
return "[$date][$level]: " . join(q{}, @message);
};
Log::Stdlog::import( {
format => \&log_format,
file => "$0.log",
level => $cmd_args_ref->{"log_level"},
} );
print $cmd_args_ref->{"log_level"};
__END__
This re-runs the import function after the program has started.
