NAME

6       Log::Message::Handlers - Message handlers for Log::Message
7

SYNOPSIS

9           # Implicitly used by Log::Message to serve as handlers for
10           # Log::Message::Item objects
11
12           # Create your own file with a package called
13           # Log::Message::Handlers to add to the existing ones, or to even
14           # overwrite them
15
16           $item->carp;
17
18           $item->trace;
19

DESCRIPTION

21       Log::Message::Handlers provides handlers for Log::Message::Item
22       objects.  The handler corresponding to the level (see
23       Log::Message::Item manpage for an explanation about levels) will be
24       called automatically upon storing the error.
25
26       Handlers may also explicitly be called on an Log::Message::Item object
27       if one so desires (see the Log::Message manpage on how to retrieve the
28       Item objects).
29

Default Handlers

31   log
32       Will simply log the error on the stack, and do nothing special
33
34   carp
35       Will carp (see the Carp manpage) with the error, and add the timestamp
36       of when it occurred.
37
38   croak
39       Will croak (see the Carp manpage) with the error, and add the timestamp
40       of when it occurred.
41
42   cluck
43       Will cluck (see the Carp manpage) with the error, and add the timestamp
44       of when it occurred.
45
46   confess
47       Will confess (see the Carp manpage) with the error, and add the
48       timestamp of when it occurred
49
50   die
51       Will simply die with the error message of the item
52
53   warn
54       Will simply warn with the error message of the item
55
56   trace
57       Will provide a traceback of this error item back to the first one that
58       occurred, clucking with every item as it comes across it.
59

Custom Handlers

61       If you wish to provide your own handlers, you can simply do the
62       following:
63
64       ·   Create a file that holds a package by the name of
65           "Log::Message::Handlers"
66
67       ·   Create subroutines with the same name as the levels you wish to
68           handle in the Log::Message module (see the Log::Message manpage for
69           explanation on levels)
70
71       ·   Require that file in your program, or add it in your configuration
72           (see the Log::Message::Config manpage for explanation on how to use
73           a config file)
74
75       And that is it, the handler will now be available to handle messages
76       for you.
77
78       The arguments a handler may receive are those specified by the "extra"
79       key, when storing the message.  See the Log::Message manpage for
80       details on the arguments.
