NAME

Log::Report::Dispatcher::Callback - call a code-ref for each log-line

INHERITANCE

 Log::Report::Dispatcher::Callback
   is a Log::Report::Dispatcher

SYNOPSIS

 sub cb($$$)
 {   my ($disp, $options, $reason, $message) = @_;
     ...
 }
 dispatcher Log::Report::Dispatcher::Callback => 'cb'
    , callback => \&cb;
 dispatcher CALLBACK => 'cb'   # same
    , callback => \&cb;

DESCRIPTION

This basic file logger accepts a callback, which is called for each message which is to be logged. When you need complex things, you may best make your own extension to Log::Report::Dispatcher, but for simple things this will do.

Extends "DESCRIPTION" in Log::Report::Dispatcher.

. Example

  sub send_mail($$$)
  {   my ($disp, $options, $reason, $message) = @_;
      my $msg = Mail::Send->new(Subject => $reason
        , To => 'admin@localhost');
      my $fh  = $msg->open('sendmail');
      print $fh $disp->translate($reason, $message);
      close $fh;
  }
  dispatcher CALLBACK => 'mail', callback => \&send_mail;

Log::Report::Dispatcher::Callback->new($type, $name, %options)

 -Option       --Defined in             --Default
  accept         Log::Report::Dispatcher  depend on mode
  callback                                <required>

  format_reason  Log::Report::Dispatcher  'LOWERCASE'
  locale         Log::Report::Dispatcher  <system locale>
  mode           Log::Report::Dispatcher  'NORMAL'

accept => REASONS
callback => CODE: Your "callback" is called with five parameters: this dispatcher object, the options, a reason and a message. The "options" are the first parameter of Log::Report::report() (read over there). The "reason" is a capitized string like "ERROR". Then, the "message" (is a Log::Report::Message). Finally the text-domain of the message.
