NAME

WWW::Google::AutoSuggest::Obj - Minimal base class for WWW::Google::AutoSuggest

SYNOPSIS

  package Cat;
  use WWW::Google::AutoSuggest::Obj -base;

  has name => 'Nyan';
  has [qw(birds mice)] => 2;

  package Tiger;
  use WWW::Google::AutoSuggest::Obj 'Cat';

  has friend  => sub { Cat->new };
  has stripes => 42;

  package main;
  use WWW::Google::AutoSuggest::Obj -strict;

  my $mew = Cat->new(name => 'Longcat');
  say $mew->mice;
  say $mew->mice(3)->birds(4)->mice;

  my $rawr = Tiger->new(stripes => 23, mice => 0);
  say $rawr->tap(sub { $_->friend->name('Tacgnol') })->mice;

DESCRIPTION

WWW::Google::AutoSuggest::Obj is a simple base class for WWW::Google::AutoSuggest, a fork of Mojo::Base.

  # Automatically enables "strict", "warnings", "utf8" and Perl 5.10 features
  use WWW::Google::AutoSuggest::Obj -strict;
  use WWW::Google::AutoSuggest::Obj -base;
  use WWW::Google::AutoSuggest::Obj 'SomeBaseClass';

All three forms save a lot of typing.

  # use WWW::Google::AutoSuggest::Obj -strict;
  use strict;
  use warnings;
  use utf8;
  use feature ':5.10';
  use IO::Handle ();

  # use WWW::Google::AutoSuggest::Obj -base;
  use strict;
  use warnings;
  use utf8;
  use feature ':5.10';
  use IO::Handle ();
  use WWW::Google::AutoSuggest::Obj;
  push @ISA, 'WWW::Google::AutoSuggest::Obj';
  sub has { WWW::Google::AutoSuggest::Obj::attr(__PACKAGE__, @_) }

  # use WWW::Google::AutoSuggest::Obj 'SomeBaseClass';
  use strict;
  use warnings;
  use utf8;
  use feature ':5.10';
  use IO::Handle ();
  require SomeBaseClass;
  push @ISA, 'SomeBaseClass';
  use WWW::Google::AutoSuggest::Obj;
  sub has { WWW::Google::AutoSuggest::Obj::attr(__PACKAGE__, @_) }

FUNCTIONS

WWW::Google::AutoSuggest::Obj implements the following functions like Mojo::Base, which can be imported with the -base flag or by setting a base class.

has

  has 'name';
  has [qw(name1 name2 name3)];
  has name => 'foo';
  has name => sub {...};
  has [qw(name1 name2 name3)] => 'foo';
  has [qw(name1 name2 name3)] => sub {...};

Create attributes for hash-based objects, just like the "attr" method.

METHODS

WWW::Google::AutoSuggest::Obj implements the following methods.

attr

  $object->attr('name');
  BaseSubClass->attr('name');
  BaseSubClass->attr([qw(name1 name2 name3)]);
  BaseSubClass->attr(name => 'foo');
  BaseSubClass->attr(name => sub {...});
  BaseSubClass->attr([qw(name1 name2 name3)] => 'foo');
  BaseSubClass->attr([qw(name1 name2 name3)] => sub {...});

Create attribute accessor for hash-based objects, an array reference can be used to create more than one at a time. Pass an optional second argument to set a default value, it should be a constant or a callback. The callback will be executed at accessor read time if there's no set value. Accessors can be chained, that means they return their invocant when they are called with an argument.

new

  my $object = BaseSubClass->new;
  my $object = BaseSubClass->new(name => 'value');
  my $object = BaseSubClass->new({name => 'value'});

This base class provides a basic constructor for hash-based objects. You can pass it either a hash or a hash reference with attribute values.

tap

  $object = $object->tap(sub {...});

K combinator, tap into a method chain to perform operations on an object within the chain. The object will be the first argument passed to the callback and is also available as $_.

DEBUGGING

You can set the AUTOSUGGEST_OBJ_DEBUG environment variable to get some advanced diagnostics information printed to STDERR.

  AUTOSUGGEST_OBJ_DEBUG=1
