| 11 | =head1 NAME | |||
| 12 | ||||
| 13 | warnings - Perl pragma to control optional warnings | |||
| 14 | ||||
| 15 | =head1 SYNOPSIS | |||
| 16 | ||||
| 17 | use warnings; | |||
| 18 | no warnings; | |||
| 19 | ||||
| 20 | use warnings "all"; | |||
| 21 | no warnings "all"; | |||
| 22 | ||||
| 23 | use warnings::register; | |||
| 24 | if (warnings::enabled()) { | |||
| 25 | warnings::warn("some warning"); | |||
| 26 | } | |||
| 27 | ||||
| 28 | if (warnings::enabled("void")) { | |||
| 29 | warnings::warn("void", "some warning"); | |||
| 30 | } | |||
| 31 | ||||
| 32 | if (warnings::enabled($object)) { | |||
| 33 | warnings::warn($object, "some warning"); | |||
| 34 | } | |||
| 35 | ||||
| 36 | warnings::warnif("some warning"); | |||
| 37 | warnings::warnif("void", "some warning"); | |||
| 38 | warnings::warnif($object, "some warning"); | |||
| 39 | ||||
| 40 | =head1 DESCRIPTION | |||
| 41 | ||||
| 42 | The C<warnings> pragma is a replacement for the command line flag C<-w>, | |||
| 43 | but the pragma is limited to the enclosing block, while the flag is global. | |||
| 44 | See L<perllexwarn> for more information. | |||
| 45 | ||||
| 46 | If no import list is supplied, all possible warnings are either enabled | |||
| 47 | or disabled. | |||
| 48 | ||||
| 49 | A number of functions are provided to assist module authors. | |||
| 50 | ||||
| 51 | =over 4 | |||
| 52 | ||||
| 53 | =item use warnings::register | |||
| 54 | ||||
| 55 | Creates a new warnings category with the same name as the package where | |||
| 56 | the call to the pragma is used. | |||
| 57 | ||||
| 58 | =item warnings::enabled() | |||
| 59 | ||||
| 60 | Use the warnings category with the same name as the current package. | |||
| 61 | ||||
| 62 | Return TRUE if that warnings category is enabled in the calling module. | |||
| 63 | Otherwise returns FALSE. | |||
| 64 | ||||
| 65 | =item warnings::enabled($category) | |||
| 66 | ||||
| 67 | Return TRUE if the warnings category, C<$category>, is enabled in the | |||
| 68 | calling module. | |||
| 69 | Otherwise returns FALSE. | |||
| 70 | ||||
| 71 | =item warnings::enabled($object) | |||
| 72 | ||||
| 73 | Use the name of the class for the object reference, C<$object>, as the | |||
| 74 | warnings category. | |||
| 75 | ||||
| 76 | Return TRUE if that warnings category is enabled in the first scope | |||
| 77 | where the object is used. | |||
| 78 | Otherwise returns FALSE. | |||
| 79 | ||||
| 80 | =item warnings::warn($message) | |||
| 81 | ||||
| 82 | Print C<$message> to STDERR. | |||
| 83 | ||||
| 84 | Use the warnings category with the same name as the current package. | |||
| 85 | ||||
| 86 | If that warnings category has been set to "FATAL" in the calling module | |||
| 87 | then die. Otherwise return. | |||
| 88 | ||||
| 89 | =item warnings::warn($category, $message) | |||
| 90 | ||||
| 91 | Print C<$message> to STDERR. | |||
| 92 | ||||
| 93 | If the warnings category, C<$category>, has been set to "FATAL" in the | |||
| 94 | calling module then die. Otherwise return. | |||
| 95 | ||||
| 96 | =item warnings::warn($object, $message) | |||
| 97 | ||||
| 98 | Print C<$message> to STDERR. | |||
| 99 | ||||
| 100 | Use the name of the class for the object reference, C<$object>, as the | |||
| 101 | warnings category. | |||
| 102 | ||||
| 103 | If that warnings category has been set to "FATAL" in the scope where C<$object> | |||
| 104 | is first used then die. Otherwise return. | |||
| 105 | ||||
