This is the condensed code of my application just for demonstrating my
problem:
use strict;
use warnings;
use Log::Log4perl qw(:easy);
use Log::Log4perl::Appender::File;
Log::Log4perl->easy_init({file=>'STDOUT',layout => '%d{HH:mm} %m%n',
level=>$DEBUG});
my $logger=Log::Log4perl::Appender::File->new(filename => "dummy.log",
mode => 'clobber');
$logger->log(message=>"test\n");
$logger->layout(Log::Log4perl::Layout::PatternLayout->new('%c %C
%m%n'));
$logger->log(message => "abc");
$logger->logdebug('xyz');
Reason for this probably slightly unusual way of using Log::Log4perl is
the following: My application
uses one common logging facility (hence the easy_init). Certain parts of
the application want to create
occasionally their various other logfiles with their own layout and
shorter lifetime than the common
logging system (demonstrated here by the variable $logger).
Running this program results in a file dummy.log containing
test
abc
and the message
Can't call method "logdebug" on an undefined value
Now my questions:
(1) Why does the second call to log() not obey the pattern layout I have
defined the line before?
After all, a Appender::File inherits from Appender, and hence layout()
should have the desired
effect.
(2) Why does the error message say "on an undefined value", when $logger
(the object where method is
called on) is obviously not undefined?
(3) I guess one of my mistakes is that Appender::File is not a suitable
logger type for my purpose.
Should I use a different logger instead, and if yes, which one?
