VERSION

version 0.02

SYNOPSIS

 #!/usr/bin/env perl

 use 5.010;

 use strict;
 use warnings;

 {
     package Animal;
     
     use Rubyish::Attribute qw(:all); 
     # use :all to import attr_accessor, attr_writer and attr_reader

     attr_accessor( [qw(name color type)] ); 
     # pass a arrayref as the only one parameter

     # then create a constructer based on hashref
     sub new {
         $class = shift;
         bless {}, $class;
     }

     1;
 }

 $dogy = Animal->new()->name("rock")
               ->color("black")->type("unknown");
 # new Animal with three attribute

 say $dogy->name;  #=> rock
 say $dogy->color; #=> black
 say $dogy->type;  #=> unknown

FUNCTIONS

attr_accessor

attr_accessor provides getters double as setters. Because all setter return instance itself, now we can manipulate object in ruby way more than ruby.

attr_accessor( [qw(name color type master)] )
$dogy = Animal->new()->name("lucky")->color("white")
              ->type("unknown")->master("shelling");

Each attribute could be read by getter as showing in synopsis.

attr_reader

attr_reader create only getter for the class you call it

attr_reader( [qw(name)] ) # pass an arrayref
$dogy = Animal->new({name => "rock"}) # if we write initialize function in constructor
$dogy->name()       #=> rock
$dogy->name("jack") #=> cause an exception.

attr_writer

attr_writer create only setter for the class you call it.

attr_writer( [qw(name)] ) # pass arrayref
$dogy = Animal->new()->name("lucky") # initialize and set and get instance itself
$dogy->name("jack") #=> instance itself 
$dogy->name         #=> undef
