Role::Commons - roles that can be commonly used, for the mutual benefit of all

 use 5.010;
 
 {
   package Local::Class;
   use Moo;
   use Role::Commons -all;
   our $AUTHORITY = 'cpan:JOEBLOGGS';
   our $VERSION   = '1.000';
 }
 
 say Local::Class->AUTHORITY
   if Local::Class->DOES('Role::Commons::Authority');
 
 my $obj = Local::Class->new;
 say $obj->object_id
   if $obj->DOES('Role::Commons::ObjectID');

Role-Commons is not yet another implementation of roles. It is a collection of generic, reusable roles that hopefully you will love to apply to your classes. These roles are built using Moo::Role, so automatically integrate into the Moose object system if you're using it, but they do not require Moose.

The Role::Commons module itself provides shortcuts for applying roles to your package, so that instead of doing:

 {
   package Local::Class;
   
   use Moo;  # or "use Moose"
   with qw( Role::Commons::Authority Role::Commons::ObjectID );
 }

You can just do this:

 {
   package Local::Class;
   
   use Moo;
   use Role::Commons qw( Authority ObjectID );
 }

It also handles passing some simple parameters through to the role from the consuming class. (Because Moo doesn't have anything like MooseX::Role::Parameterized.)

Sets up a "AUTHORITY" method for your class which is conceptually a little like "VERSION".
Provides an "object_id" method for your class which returns a unique identifier for each object.
Provides a "tap" method for your class, inspired by Ruby's method of the same name. Helpful for writing chained method calls.

Role-Commons is the successor for my older projects: authority-shared, Object-AUTHORITY, Object-DOES, Object-Role, and Object-Tap.

Role-Commons bundles Object::AUTHORITY for the sake of backwards compatibility. This is being phased out.

Please report any bugs to <http://rt.cpan.org/Dist/Display.html?Queue=Role-Commons>.
