NAME

Mojo::Log::Role::Format - Add sprintf logging to Mojo::Log

SYNOPSIS

            

              
              
use Mojo::Log;
my $log = Mojo::Log->new->with_roles('+Format')->level('debug');
# [info] cool beans
$log->logf(info => 'cool %s', 'beans');
# [warn] serializing {"data":"structures"}
$log->logf(warn => 'serializing %s', {data => 'structures'});
            
          

DESCRIPTION

Mojo::Log::Role::Format is a Mojo::Log role which allow you to log with a format like sprintf(), avoid "Use of uninitialized" warnings and will also serialize data-structures and objects.

ATTRIBUTES

logf_serialize

            

              
              
$cb = $log->logf_serialize;
$log = $log->logf_serialize(sub (@args) { ... });
            
          

This attribute must hold a callback that will be used to serialize the arguments passed to "logf".

The default callback uses Data::Dumper with some modifications, but these settings are currently EXPERIMENTAL and subject to change:

            

              
              
$Data::Dumper::Indent    = 0;
$Data::Dumper::Maxdepth  = $Data::Dumper::Maxdepth || 2;
$Data::Dumper::Pair      = ':';
$Data::Dumper::Quotekeys = 1;
$Data::Dumper::Sortkeys  = 1;
$Data::Dumper::Terse     = 1;
$Data::Dumper::Useqq     = 1;
            
          

METHODS

logf

            

              
              
$log = $log->logf($level => $format, @args);
$log = $log->logf($level => $message);
