32 This module is a simple logger made mostly for demonstration and
33 initial experimentation with Log::Contextual. We recommend you use a
34 real logger instead. For something more serious but not overly
35 complicated, take a look at Log::Dispatchouli.

38 new
39 Arguments: "Dict[ levels => ArrayRef[Str], coderef => Optional[CodeRef]
40 ] $conf"
41
42 my $l = Log::Contextual::SimpleLogger->new({
43 levels => [qw( info warn )],
44 coderef => sub { print @_ }, # the default prints to STDERR
45 });
46
47 Creates a new SimpleLogger object with the passed levels enabled and
48 optionally a "CodeRef" may be passed to modify how the logs are
49 output/stored.
50
51 Levels may contain:
52
53 trace
54 debug
55 info
56 warn
57 error
58 fatal
59
60 $level
61 Arguments: @anything
62
63 All of the following six methods work the same. The basic pattern is:
64
65 sub $level {
66 my $self = shift;
67
68 print STDERR "[$level] " . join qq{\n}, @_;
69 if $self->is_$level;
70 }
71
72 trace
73
74 $l->trace( 'entered method foo with args ' join q{,}, @args );
75
76 debug
77
78 $l->debug( 'entered method foo' );
79
80 info
81
82 $l->info( 'started process foo' );
83
84 warn
85
86 $l->warn( 'possible misconfiguration at line 10' );
87
88 error
89
90 $l->error( 'non-numeric user input!' );
91
92 fatal
93
94 $l->fatal( '1 is never equal to 0!' );
95
96 Note: "fatal" does not call "die" for you, see "EXCEPTIONS AND ERROR
97 HANDLING" in Log::Contextual
98
99 is_$level
100 All of the following six functions just return true if their respective
101 level is enabled.
102
103 is_trace
104
105 say 'tracing' if $l->is_trace;
106
107 is_debug
108
109 say 'debuging' if $l->is_debug;
110
111 is_info
112
113 say q{info'ing} if $l->is_info;
114
115 is_warn
116
117 say 'warning' if $l->is_warn;
118
119 is_error
120
121 say 'erroring' if $l->is_error;
122
123 is_fatal
124
125 say q{fatal'ing} if $l->is_fatal;
