NAME

6       MooX::Role::Logger - Provide logging via Log::Any
7

VERSION

9       version 0.005
10

SYNOPSIS

12       In your modules:
13
14           package MyModule;
15           use Moose;
16           with 'MooX::Role::Logger';
17
18           sub run {
19               my ($self) = @_;
20               $self->cry;
21           }
22
23           sub cry {
24               my ($self) = @_;
25               $self->_logger->info("I'm sad");
26           }
27
28       In your application:
29
30           use MyModule;
31           use Log::Any::Adapter ('File', '/path/to/file.log');
32
33           MyModule->run;
34

DESCRIPTION

36       This role provides universal logging via Log::Any.  The class using
37       this role doesn't need to know or care about the details of log
38       configuration, implementation or destination.
39
40       Use it when you want your module to offer logging capabilities, but
41       don't know who is going to use your module or what kind of logging they
42       will implement.  This role lets you do your part and leaves actual log
43       setup and routing to someone else.
44
45       The application that ultimately uses your module can then choose to
46       direct log messages somewhere based on its own needs and configuration
47       with Log::Any::Adapter.
48
49       This role is based on Moo so it should work with either Moo or Moose
50       based classes.
51

USAGE

53   Testing
54       Testing with Log::Any is pretty easy, thanks to Log::Any::Test.  Just
55       load that before Log::Any loads and your log messages get sent to a
56       test adapter that includes testing methods:
57
58           use Test::More 0.96;
59           use Log::Any::Test;
60           use Log::Any qw/$log/;
61
62           use lib 't/lib';
63           use MyModule;
64
65           MyModule->new->cry;
66           $log->contains_ok( qr/I'm sad/, "got log message" );
67
68           done_testing;
69
70   Customizing
71       If you have a whole set of classes that should log with a single
72       category, create your own role and set the "_build__logger_category"
73       there:
74
75           package MyLibrary::Role::Logger;
76           use Moo::Role;
77           with 'MooX::Role::Logger';
78
79           sub _build__logger_category { "MyLibrary" }
80
81       Then in your other classes, use your custom role:
82
83           package MyLibrary::Foo;
84           use Moo;
85           with 'MyLibrary::Role::Logger'
86

METHODS

88   _logger
89       Returns a logging object.  See Log::Any for a list of logging methods
90       it accepts.
91
92   _build__logger_category
93       Override to set the category used for logging.  Defaults to the class
94       name of the object (which could be a subclass).  You can override to
95       lock it to a particular name:
96
97           sub _build__logger_category { __PACKAGE__ }
98

SEE ALSO

100       Since MooX::Role::Logger is universal, you have to use it with one of
101       several Log::Any::Adapter classes:
102
103       •   Log::Any::Adapter::File
104
105       •   Log::Any::Adapter::Stderr
106
107       •   Log::Any::Adapter::Stdout
108
109       •   Log::Any::Adapter::ScreenColoredLevel
110
111       •   Log::Any::Adapter::Dispatch
112
113       •   Log::Any::Adapter::Syslog
114
115       •   Log::Any::Adapter::Log4perl
116
117       These other logging roles are specific to particular logging packages,
118       rather than being universal:
119
120       •   MooseX::LazyLogDispatch
121
122       •   MooseX::Log::Log4perl
123
124       •   MooseX::LogDispatch
125
126       •   MooseX::Role::LogHandler
127
128       •   MooseX::Role::Loggable (uses Log::Dispatchouli)
129
130       •   Role::Log::Syslog::Fast
131
