log::message::handlers
Log::Message::Handlers(3pm) Perl Programmers Reference Guide Log::Message::Handlers(3pm)
NAME
Log::Message::Handlers - Message handlers for Log::Message
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;
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).
Default Handlers
log
Will simply log the error on the stack, and do nothing special
carp
Will carp (see the Carp manpage) with the error, and add the timestamp of when it occurred.
croak
Will croak (see the Carp manpage) with the error, and add the timestamp of when it occurred.
cluck
Will cluck (see the Carp manpage) with the error, and add the timestamp of when it occurred.
confess
Will confess (see the Carp manpage) with the error, and add the timestamp of when it occurred
die
Will simply die with the error message of the item
warn
Will simply warn with the error message of the item
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.
Custom Handlers
If you wish to provide your own handlers, you can simply do the following:
o Create a file that holds a package by the name of "Log::Message::Handlers"
o 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)
o 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)
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 "extra" key, when storing the message. See the Log::Message manpage for
details on the arguments.
