Yes, without argument, the error is normal :

$ perl test.pl
Use of uninitialized value in hash element at /usr/local/share/perl/5.10.0/Log/StdLog.pm line 57.
Use of uninitialized value in string at test.pl line 25.

But with an argument like this :

$ perl test.pl --log-level=info
Use of uninitialized value in hash element at /usr/local/share/perl/5.10.0/Log/StdLog.pm line 57.
info

level => $cmd_args_ref->{"log_level"} stay undef and
print $cmd_args_ref->{"log_level"}; return the good value.

I don't understand why in : use Log::StdLog {...}, the value of $cmd_args_ref->{"log_level"} stay always undef???


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"},
} );

Oops, try this instead:

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.

Thx but adding __END__ return me this error, anyway the problem is solve with a BEGIN block (cf.Rob Dixon).

$ perl test.pl --log-level=debug
Name "main::STDLOG" used only once: possible typo at /usr/local/share/perl/5.10.0/Log/StdLog.pm line 51

Thx again.
