- Release of version 0.78 of Attribute::Handlers

-
- NAME
- Attribute::Handlers - Simpler definition of attribute handlers
-
- DESCRIPTION
- This module, when inherited by a package, allows that package's class to
- define attribute handler subroutines for specific attributes. Variables
- and subroutines subsequently defined in that package, or in packages
- derived from that package may be given attributes with the same names as
- the attribute handler subroutines, which will then be called at the end
- of the compilation phase (i.e. in a `CHECK' block).
-
- EXAMPLE
-
- package UNIVERSAL;
- use Attribute::Handlers;
-
- my %name;
- sub name { return $name{$_[2]}||*{$_[1]}{NAME} }
-
- sub Name :ATTR { $name{$_[2]} = $_[4] }
-
- sub Purpose :ATTR { print STDERR "Purpose of ", &name, " is $_[4]\n" }
-
- sub Unit :ATTR { print STDERR &name, " measured in $_[4]\n" }
-
-
- package main;
-
- my $capacity : Name(capacity)
- : Purpose(to store max storage capacity for files)
- : Unit(Gb);
-
- package Other;
-
- sub foo : Purpose(to foo all data before barring it) { }

- - [#17940] Includes :unique and :shared in the builtin types

- - From perl 5.8 { __CALLER__::foo => __PACKAGE } is missparsed,
- the proper approach is to use { '__CALLER__::foo' => __PACKAGE }.
- The documentation is updated to reflect this.
