47 | =head1 DESCRIPTION | ||||
48 | |||||
49 | The C<warnings> pragma is a replacement for the command line flag C<-w>, | ||||
50 | but the pragma is limited to the enclosing block, while the flag is global. | ||||
51 | See L<perllexwarn> for more information. | ||||
52 | |||||
53 | If no import list is supplied, all possible warnings are either enabled | ||||
54 | or disabled. | ||||
55 | |||||
56 | A number of functions are provided to assist module authors. | ||||
57 | |||||
58 | =over 4 | ||||
59 | |||||
60 | =item use warnings::register | ||||
61 | |||||
62 | Creates a new warnings category with the same name as the package where | ||||
63 | the call to the pragma is used. | ||||
64 | |||||
65 | =item warnings::enabled() | ||||
66 | |||||
67 | Use the warnings category with the same name as the current package. | ||||
68 | |||||
69 | Return TRUE if that warnings category is enabled in the calling module. | ||||
70 | Otherwise returns FALSE. | ||||
71 | |||||
72 | =item warnings::enabled($category) | ||||
73 | |||||
74 | Return TRUE if the warnings category, C<$category>, is enabled in the | ||||
75 | calling module. | ||||
76 | Otherwise returns FALSE. | ||||
77 | |||||
78 | =item warnings::enabled($object) | ||||
79 | |||||
80 | Use the name of the class for the object reference, C<$object>, as the | ||||
81 | warnings category. | ||||
82 | |||||
83 | Return TRUE if that warnings category is enabled in the first scope | ||||
84 | where the object is used. | ||||
85 | Otherwise returns FALSE. | ||||
86 | |||||
87 | =item warnings::fatal_enabled() | ||||
88 | |||||
89 | Return TRUE if the warnings category with the same name as the current | ||||
90 | package has been set to FATAL in the calling module. | ||||
91 | Otherwise returns FALSE. | ||||
92 | |||||
93 | =item warnings::fatal_enabled($category) | ||||
94 | |||||
95 | Return TRUE if the warnings category C<$category> has been set to FATAL in | ||||
96 | the calling module. | ||||
97 | Otherwise returns FALSE. | ||||
98 | |||||
99 | =item warnings::fatal_enabled($object) | ||||
100 | |||||
101 | Use the name of the class for the object reference, C<$object>, as the | ||||
102 | warnings category. | ||||
103 | |||||
104 | Return TRUE if that warnings category has been set to FATAL in the first | ||||
105 | scope where the object is used. | ||||
106 | Otherwise returns FALSE. | ||||
107 | |||||
108 | =item warnings::warn($message) | ||||
109 | |||||
110 | Print C<$message> to STDERR. | ||||
111 | |||||
112 | Use the warnings category with the same name as the current package. | ||||
113 | |||||
114 | If that warnings category has been set to "FATAL" in the calling module | ||||
115 | then die. Otherwise return. | ||||
116 | |||||
117 | =item warnings::warn($category, $message) | ||||
118 | |||||
119 | Print C<$message> to STDERR. | ||||
120 | |||||
121 | If the warnings category, C<$category>, has been set to "FATAL" in the | ||||
122 | calling module then die. Otherwise return. | ||||
123 | |||||
124 | =item warnings::warn($object, $message) | ||||
125 | |||||
126 | Print C<$message> to STDERR. | ||||
127 | |||||
128 | Use the name of the class for the object reference, C<$object>, as the | ||||
129 | warnings category. | ||||
130 | |||||
131 | If that warnings category has been set to "FATAL" in the scope where C<$object> | ||||
132 | is first used then die. Otherwise return. | ||||
