NAME

       Moo::Role - Minimal Object Orientation support for Roles

SYNOPSIS

	package My::Role;

	use Moo::Role;

	sub foo { ... }

	sub bar { ... }

	has baz => (
	  is => 'ro',
	);

	1;

       And elsewhere:

	package Some::Class;

	use Moo;

	# 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.  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: "Can't locate object method "md5_hex"".

       See "CLEANING UP IMPORTS" in Moo for more details.
