NAME 🖥️ Moo_Rolepm 🖥️

Minimal Object Orientation support for Roles

SYNOPSIS

package My::Role; use Moo::Role; use strictures 2; sub foo { … } sub bar { … } has baz => ( is => ro, ); 1;

And elsewhere:

package Some::Class; use Moo; use strictures 2; # bar gets imported, but not foo with My::Role; sub foo { … } 1;

DESCRIPTION

Moo::Role builds upon Role::Tiny, so look there for most of the documentation on how this works (in particular, using Moo::Role also enables strict and warnings). The main addition here is extra bits to make the roles more Moosey; which is to say, it adds has.

IMPORTED SUBROUTINES

See IMPORTED SUBROUTINES in Role::Tiny for all the other subroutines that are imported by this module.

has

has attr => ( is => ro, );

Declares an attribute for the class to be composed into. See has in Moo for all options.

CLEANING UP IMPORTS

Moo::Role cleans up its own imported methods and any imports declared before the use Moo::Role statement automatically. Anything imported after use Moo::Role will be composed into consuming packages. A package that consumes this role:

package My::Role::ID; use Digest::MD5 qw(md5_hex); use Moo::Role; use Digest::SHA qw(sha1_hex); requires name; sub as_md5 { my ($self) = @_; return md5_hex($self->name); } sub as_sha1 { my ($self) = @_; return sha1_hex($self->name); } 1;

..will now have a $self->sha1_hex() method available to it that probably does not do what you expect. On the other hand, a call to $self->md5_hex() will die with the helpful error message: Cant locate object method "md5_hex".

See CLEANING UP IMPORTS in Moo for more details.
