NAME

MooseX::Log::Log4perl - A Logging Role for Moose based on Log::Log4perl

VERSION

This document describes MooseX::Log::Log4perl version 0.30

SYNOPSIS

 package MyApp;
 use Moose;
 use Log::Log4perl qw(:easy);

 with 'MooseX::Log::Log4perl';

 BEGIN {
   Log::Log4perl->easy_init();
 }

 sub foo {
   my ($self) = @_;
   $self->log->debug("started bar");    ### logs with default class catergory "MyApp"
   ...
   $self->log('special')->info('bar');  ### logs with category special
 }

DESCRIPTION

A logging role building a very lightweight wrapper to Log::Log4perl for use with your Moose classes. The initialization of the Log4perl instance must be performed prior to logging the first log message. Otherwise the default initialization will happen, probably not doing the things you expect.

For compatibility the logger attribute can be accessed to use a common interface for application logging.

For simple logging needs use MooseX::Log::Log4perl::Easy to directly add log_<level> methods to your class instance.

    $self->log_info("Dummy");

ACCESSORS

logger

The logger attribute holds the Log::Log4perl object that implements all logging methods for the defined log levels, such as debug or error. As this method is defined also in other logging roles/systems like MooseX::Log::LogDispatch this can be thought of as a common logging interface.

  package MyApp::View::JSON;

  extends 'MyApp::View';
  with 'MooseX:Log::Log4perl';

  sub bar {
    $self->logger->debug("Something could be crappy here");     # logs a debug message
    $self->logger->debug("Something could be crappy here");     # logs a debug message
  }

log

A shorter alias for logger, but also allowing to change the log category this method call.

 if ($myapp->log->is_debug()) {
     $myapp->log->debug("Woot"); # category is class myapp
 }
 $myapp->log("TempCat")->info("Foobar"); # category TempCat
 $myapp->log->info("Grumble"); # category class again myapp
