=head1 NAME
Log::Any::Adapter::Callback - Send Log::Any logs to a subroutine
=head1 VERSION
version 0.09
=head1 SYNOPSIS
# say, let's POST each log message to an HTTP API server
use LWP::UserAgent;
my $ua = LWP::UserAgent->new;
use Log::Any::Adapter;
Log::Any::Adapter->set('Callback',
min_level => 'warn',
logging_cb => sub {
my ($method, $self, $format, @params) = @_;
$ua->post("https://localdomain/log", level=>$method, Content=>$format);
sleep 1; # don't overload the server
},
detection_cb => sub { ... }, # optional, default is: sub { 1 }
);
=head1 DESCRIPTION
This adapter lets you specify callback subroutine to be called by Log::Any's
logging methods (like $log->debug(), $log->error(), etc) and detection methods
(like $log->is_warning(), $log->is_fatal(), etc.).
This adapter is used for customized logging, and is mostly a convenient
construct to save a few lines of code. You could achieve the same effect by
creating a full Log::Any adapter class.
Your logging callback subroutine will be called with these arguments:
($method, $self, $format, @params)
where $method is the name of method (like "debug") and ($self, $format, @params)
are given by Log::Any.
