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>
 charset        Log::Report::Dispatcher  <undef>
 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.

charset => CHARSET

format_reason => 'UPPERCASE'|'LOWERCASE'|'UCFIRST'|'IGNORE'|CODE

locale => LOCALE

mode => 'NORMAL'|'VERBOSE'|'ASSERT'|'DEBUG'|0..3
