NAME

       Mojo::Base - Minimal base class for Mojo projects

SYNOPSIS

         package Cat;
         use Mojo::Base -base;

         has name => 'Nyan';
         has [qw(age weight)] => 4;

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

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

         package main;
         use Mojo::Base -strict;

         my $mew = Cat->new(name => 'Longcat');
         say $mew->age;
         say $mew->age(3)->weight(5)->age;

         my $rawr = Tiger->new(stripes => 38, weight => 250);
         say $rawr->tap(sub { $_->friend->name('Tacgnol') })->weight;

DESCRIPTION

       Mojo::Base is a simple base class for Mojo projects with fluent interfaces.

         # Automatically enables "strict", "warnings", "utf8" 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 utf8;
         use feature ':5.10';
         use IO::Handle ();

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

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

FUNCTIONS

       Mojo::Base implements the following functions, 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

       Mojo::Base implements the following methods.

   attr
         $object->attr('name');
         SubClass->attr('name');
         SubClass->attr([qw(name1 name2 name3)]);
         SubClass->attr(name => 'foo');
         SubClass->attr(name => sub {...});
         SubClass->attr([qw(name1 name2 name3)] => 'foo');
         SubClass->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 = SubClass->new;
         my $object = SubClass->new(name => 'value');
         my $object = SubClass->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 {...});
         $object = $object->tap($method);
         $object = $object->tap($method, @args);

       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 $_.

         # Longer version
         $object = $object->tap(sub { $_->$method(@args) });

         # Inject side effects into a method chain
         $object->foo('A')->tap(sub { say $_->foo })->foo('B');
