| 46 | |||||
| 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::warn($message) | ||||
| 88 | |||||
| 89 | Print C<$message> to STDERR. | ||||
| 90 | |||||
| 91 | Use the warnings category with the same name as the current package. | ||||
| 92 | |||||
| 93 | If that warnings category has been set to "FATAL" in the calling module | ||||
| 94 | then die. Otherwise return. | ||||
| 95 | |||||
| 96 | =item warnings::warn($category, $message) | ||||
| 97 | |||||
| 98 | Print C<$message> to STDERR. | ||||
| 99 | |||||
| 100 | If the warnings category, C<$category>, has been set to "FATAL" in the | ||||
| 101 | calling module then die. Otherwise return. | ||||
| 102 | |||||
| 103 | =item warnings::warn($object, $message) | ||||
| 104 | |||||
| 105 | Print C<$message> to STDERR. | ||||
| 106 | |||||
| 107 | Use the name of the class for the object reference, C<$object>, as the | ||||
| 108 | warnings category. | ||||
| 109 | |||||
| 110 | If that warnings category has been set to "FATAL" in the scope where C<$object> | ||||
| 111 | is first used then die. Otherwise return. | ||||
