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