=head1 NAME
Log::Message::Handlers - Message handlers for Log::Message
=head1 SYNOPSIS
# Implicitly used by Log::Message to serve as handlers for
# Log::Message::Item objects
# Create your own file with a package called
# Log::Message::Handlers to add to the existing ones, or to even
# overwrite them
$item->carp;
$item->trace;
=head1 DESCRIPTION
Log::Message::Handlers provides handlers for Log::Message::Item objects.
The handler corresponding to the level (see Log::Message::Item manpage
for an explanation about levels) will be called automatically upon
storing the error.
Handlers may also explicitly be called on an Log::Message::Item object
if one so desires (see the Log::Message manpage on how to retrieve the
Item objects).
=head1 Default Handlers
=head2 log
Will simply log the error on the stack, and do nothing special
=cut
sub log { 1 }
=head2 carp
Will carp (see the Carp manpage) with the error, and add the timestamp
of when it occurred.
=cut
sub carp {
my $self = shift;
warn join " ", $self->message, $self->shortmess, 'at', $self->when, "\n";
}
=head2 croak
Will croak (see the Carp manpage) with the error, and add the
timestamp of when it occurred.
=cut
sub croak {
my $self = shift;
die join " ", $self->message, $self->shortmess, 'at', $self->when, "\n";
}
=head2 cluck
Will cluck (see the Carp manpage) with the error, and add the
timestamp of when it occurred.
=cut
sub cluck {
my $self = shift;
warn join " ", $self->message, $self->longmess, 'at', $self->when, "\n";
}
=head2 confess
Will confess (see the Carp manpage) with the error, and add the
timestamp of when it occurred
=cut
sub confess {
my $self = shift;
die join " ", $self->message, $self->longmess, 'at', $self->when, "\n";
}
=head2 die
Will simply die with the error message of the item
=cut
sub die { die shift->message; }
=head2 warn
Will simply warn with the error message of the item
=cut
sub warn { warn shift->message; }
=head2 trace
Will provide a traceback of this error item back to the first one that
occurred, clucking with every item as it comes across it.
=cut
sub trace {
my $self = shift;
for my $item( $self->parent->retrieve( chrono => 0 ) ) {
$item->cluck;
}
}
=head1 Custom Handlers
If you wish to provide your own handlers, you can simply do the
following:
=over 4
=item *
Create a file that holds a package by the name of
C<Log::Message::Handlers>
=item *
Create subroutines with the same name as the levels you wish to
handle in the Log::Message module (see the Log::Message manpage for
explanation on levels)
=item *
Require that file in your program, or add it in your configuration
(see the Log::Message::Config manpage for explanation on how to use a
config file)
=back
And that is it, the handler will now be available to handle messages
for you.
The arguments a handler may receive are those specified by the
C<extra> key, when storing the message.
See the Log::Message manpage for details on the arguments.
