Simo is framework that simplify Object Oriented Perl.

The feature is that

SYNOPSIS

#Class definition
package Book;
use Simo;

sub title{ ac }
sub author{ ac }
sub price{ ac }

# Using class
use Book;
my $book = Book->new( title => 'a', author => 'b', price => 1000 );

# Default value of attribute
sub author{ ac default => 'Kimoto' }

#Automatically build of attribute
sub author{ ac auto_build => 1 }
sub build_author{ 
    my $self = shift;
    $self->author( $self->title . "b" );
}

sub title{ ac default => 'a' }

# Constraint of attribute setting
use Simo::Constrain qw( is_int isa );
sub price{ ac constrain => sub{ is_int } }
sub author{ ac constrain => sub{ isa 'Person' } }

# Filter of attribute setting
sub author{ ac filter => sub{ uc } }

# Trigger of attribute setting

sub date{ ac trigger => sub{ $_->year( substr( $_->date, 0, 4 ) ) } } 
sub year{ ac }

# Read only accessor
sub year{ ac read_only => 1 }

# Hash ref convert of attribute setting
sub country_id{ ac hash_force => 1 }

# Required attributes
sub REQUIRED_ATTRS{ qw( title author ) }

# Inheritance
package Magazine;
use Simo( base => 'Book' );

# Mixin
package Book;
use Simo( mixin => 'Class::Cloneable' );

# new method include

new

new method is prepared.

use Book;
my $book = Book->new( title => 'a', author => 'b', price => 1000 );

new_self_and_parent

new_self_and_parent resolve the inheritance of no Simo based class;

$self->new_self_and_parent( @_, [ 'title', 'author' ] );

$self->new_self_and_parent( { self_args => [], parent_args => [] } );

REQUIRED_ATTRS
