NAME

MooX::Role::Parameterized - roles with composition parameters

SYNOPSYS

package My::Role;

use Moo::Role;
use MooX::Role::Parameterized;

role {
    my $params = shift;

    hasp $params->{attr} => ( is => 'rw' );

    method $params->{method} => sub {
        1024;
    };
};

package My::Class;

use Moo;
# experimental way of add roles
use MooX::Role::Parameterized::With My::Role => {
    attr => 'baz',
    method => 'run'
};

package My::OldClass;

use Moo;
use My::Role;

My::Role->apply([{    # original way of add this role
    attr => 'baz',    # add attribute read-write called 'baz' 
    method => 'run'   # add method called 'run' and return 1024 
}
 ,                    # and if the apply receives one arrayref
{   attr => 'bam',    # will call the role block multiple times.
    method => 'jump'  # PLEASE CALL apply once
}]);

DESCRIPTION

It is an experimental port of MooseX::Role::Parameterized to Moo.

FUNCTIONS

This package exports four subroutines: hasp, apply, role and method.

hasp

IMPORTANT: until the version 0.06 we have a terrible bug when you try to add the same role in two or more different classes. To avoid this we should not call the has method to specify attributes but the method hasp (means 'has parameterized').

apply

When called, will apply the "role" on the current package. The behavior depends of the parameter list.

This will install the role in the target package. Does not need call with.

Important, if you want to apply the role multiple times, like to create multiple attributes, please pass an arrayref.

role

This function accepts one code block. Will execute this code then we apply the Role in the target class, and will receive the parameter list.

method

Add one method based on the parameter list, for example.

MooX::Role::Parameterized::With

See MooX::Role::Parameterized::With package to easily load and apply roles.
