NAME

Mojo::Base - Minimal base class for Mojo projects

SYNOPSIS

  package Cat;
  use Mojo::Base -base;

  has 'mouse';
  has paws => 4;
  has [qw/ears eyes/] => 2;

  package Tiger;
  use Mojo::Base 'Cat';

  has stripes => 42;

  package main;

  my $mew = Cat->new(mouse => 'Mickey');
  say $mew->paws;
  say $mew->paws(5)->paws;

  my $rawr = Tiger->new(stripes => 23);
  say $rawr->ears * $rawr->stripes;

DESCRIPTION

Mojo::Base is a simple base class for Mojo projects.

  # Automatically enables "strict", "warnings" and Perl 5.10 features
  use Mojo::Base -strict;
  use Mojo::Base -base;
  use Mojo::Base 'SomeBaseClass';

All three forms save a lot of typing.

  # use Mojo::Base -strict;
  use strict;
  use warnings;
  use feature ':5.10';

  # use Mojo::Base -base;
  use strict;
  use warnings;
  use feature ':5.10';
  use Mojo::Base;
  push @ISA, 'Mojo::Base';
  sub has { Mojo::Base::attr(__PACKAGE__, @_) }

  # use Mojo::Base 'SomeBaseClass';
  use strict;
  use warnings;
  use feature ':5.10';
  require SomeBaseClass;
  push @ISA, 'SomeBaseClass';
  use Mojo::Base;
  sub has { Mojo::Base::attr(__PACKAGE__, @_) }

FUNCTIONS

Mojo::Base exports the following functions if imported with the -base flag or 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, just like the attr method.

METHODS

Mojo::Base implements the following methods.

new

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

This base class provides a basic object constructor. You can pass it either a hash or a hash reference with attribute values.

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 attributes. An arrayref can be used to create more than one attribute. Pass an optional second argument to set a default value, it should be a constant or a sub reference. The sub reference will be excuted at accessor read time if there's no set value.

DEBUGGING

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

  MOJO_BASE_DEBUG=1
