247 This module is an extremely light-weight subset of L<Moose> optimised for
248 rapid startup and "pay only for what you use".
250 It also avoids depending on any XS modules to allow simple deployments. The
251 name C<Moo> is based on the idea that it provides almost -- but not quite -- two
254 Unlike L<Mouse> this module does not aim at full compatibility with
255 L<Moose>'s surface syntax, preferring instead of provide full interoperability
256 via the metaclass inflation capabilities described in L</MOO AND MOOSE>.
258 For a full list of the minor differences between L<Moose> and L<Moo>'s surface
259 syntax, see L</INCOMPATIBILITIES WITH MOOSE>.
261 =head1 WHY MOO EXISTS
263 If you want a full object system with a rich Metaprotocol, L<Moose> is
266 However, sometimes you're writing a command line script or a CGI script
267 where fast startup is essential, or code designed to be deployed as a single
268 file via L<App::FatPacker>, or you're writing a CPAN module and you want it
269 to be usable by people with those constraints.
271 I've tried several times to use L<Mouse> but it's 3x the size of Moo and
272 takes longer to load than most of my Moo based CGI scripts take to run.
274 If you don't want L<Moose>, you don't want "less metaprotocol" like L<Mouse>,
275 you want "as little as possible" -- which means "no metaprotocol", which is
278 Better still, if you install and load L<Moose>, we set up metaclasses for your
279 L<Moo> classes and L<Moo::Role> roles, so you can use them in L<Moose> code
280 without ever noticing that some of your codebase is using L<Moo>.
282 Hence, Moo exists as its name -- Minimal Object Orientation -- with a pledge
283 to make it smooth to upgrade to L<Moose> when you need more than minimal
288 If L<Moo> detects L<Moose> being loaded, it will automatically register
289 metaclasses for your L<Moo> and L<Moo::Role> packages, so you should be able
290 to use them in L<Moose> code without anybody ever noticing you aren't using
293 L<Moo> will also create L<Moose type constraints|Moose::Manual::Types> for
294 classes and roles, so that C<< isa => 'MyClass' >> and C<< isa => 'MyRole' >>
295 work the same as for L<Moose> classes and roles.
297 Extending a L<Moose> class or consuming a L<Moose::Role> will also work.
299 So will extending a L<Mouse> class or consuming a L<Mouse::Role> - but note
300 that we don't provide L<Mouse> metaclasses or metaroles so the other way
301 around doesn't work. This feature exists for L<Any::Moose> users porting to
302 L<Moo>; enabling L<Mouse> users to use L<Moo> classes is not a priority for us.
304 This means that there is no need for anything like L<Any::Moose> for Moo
305 code - Moo and Moose code should simply interoperate without problem. To
306 handle L<Mouse> code, you'll likely need an empty Moo role or class consuming
307 or extending the L<Mouse> stuff since it doesn't register true L<Moose>
308 metaclasses like L<Moo> does.
310 If you want types to be upgraded to the L<Moose> types, use
311 L<MooX::Types::MooseLike> and install the L<MooseX::Types> library to
312 match the L<MooX::Types::MooseLike> library you're using - L<Moo> will
313 load the L<MooseX::Types> library and use that type for the newly created
316 If you need to disable the metaclass creation, add:
320 to your code before Moose is loaded, but bear in mind that this switch is
321 currently global and turns the mechanism off entirely so don't put this
324 =head1 MOO AND CLASS::XSACCESSOR
326 If a new enough version of L<Class::XSAccessor> is available, it
327 will be used to generate simple accessors, readers, and writers for
328 a speed boost. Simple accessors are those without lazy defaults,
329 type checks/coercions, or triggers. Readers and writers generated
330 by L<Class::XSAccessor> will behave slightly differently: they will
331 reject attempts to call them with the incorrect number of parameters.
333 =head1 MOO VERSUS ANY::MOOSE
335 L<Any::Moose> will load L<Mouse> normally, and L<Moose> in a program using
336 L<Moose> - which theoretically allows you to get the startup time of L<Mouse>
337 without disadvantaging L<Moose> users.
339 Sadly, this doesn't entirely work, since the selection is load order dependent
340 - L<Moo>'s metaclass inflation system explained above in L</MOO AND MOOSE> is
341 significantly more reliable.
343 So if you want to write a CPAN module that loads fast or has only pure perl
344 dependencies but is also fully usable by L<Moose> users, you should be using
347 For a full explanation, see the article
348 L<http://shadow.cat/blog/matt-s-trout/moo-versus-any-moose> which explains
349 the differing strategies in more detail and provides a direct example of
350 where L<Moo> succeeds and L<Any::Moose> fails.
352 =head1 IMPORTED METHODS
356 Foo::Bar->new( attr1 => 3 );
360 Foo::Bar->new({ attr1 => 3 });
365 my ( $class, @args ) = @_;
367 unshift @args, "attr1" if @args % 2 == 1;
374 The default implementation of this method accepts a hash or hash reference of
375 named parameters. If it receives a single argument that isn't a hash reference
378 You can override this method in your class to handle other types of options
379 passed to the constructor.
381 This method should always return a hash reference of named options.
383 =head2 FOREIGNBUILDARGS
385 If you are inheriting from a non-Moo class, the arguments passed to the parent
386 class constructor can be manipulated by defining a C<FOREIGNBUILDARGS> method.
387 It will receive the same arguments as C<BUILDARGS>, and should return a list
388 of arguments to pass to the parent class constructor.
392 Define a C<BUILD> method on your class and the constructor will automatically
393 call the C<BUILD> method from parent down to child after the object has
394 been instantiated. Typically this is used for object validation or possibly
399 If you have a C<DEMOLISH> method anywhere in your inheritance hierarchy,
400 a C<DESTROY> method is created on first object construction which will call
401 C<< $instance->DEMOLISH($in_global_destruction) >> for each C<DEMOLISH>
402 method from child upwards to parents.
404 Note that the C<DESTROY> method is created on first construction of an object
405 of your class in order to not add overhead to classes without C<DEMOLISH>
406 methods; this may prove slightly surprising if you try and define your own.
410 if ($foo->does('Some::Role1')) {
414 Returns true if the object composes in the passed role.
416 =head1 IMPORTED SUBROUTINES
420 extends 'Parent::Class';
422 Declares base class. Multiple superclasses can be passed for multiple
423 inheritance (but please use roles instead).
425 Calling extends more than once will REPLACE your superclasses, not add to
426 them like 'use base' would.
434 with 'Some::Role1', 'Some::Role2';
436 Composes one or more L<Moo::Role> (or L<Role::Tiny>) roles into the current
437 class. An error will be raised if these roles have conflicting methods.
445 Declares an attribute for the class.
457 default => sub { "blah" },
460 Using the C<+> notation, it's possible to override an attribute.
462 The options for C<has> are as follows:
468 B<required>, may be C<ro>, C<lazy>, C<rwp> or C<rw>.
470 C<ro> generates an accessor that dies if you attempt to write to it - i.e.
471 a getter only - by defaulting C<reader> to the name of the attribute.
473 C<lazy> generates a reader like C<ro>, but also sets C<lazy> to 1 and
474 C<builder> to C<_build_${attribute_name}> to allow on-demand generated
475 attributes. This feature was my attempt to fix my incompetence when
476 originally designing C<lazy_build>, and is also implemented by
477 L<MooseX::AttributeShortcuts>. There is, however, nothing to stop you
478 using C<lazy> and C<builder> yourself with C<rwp> or C<rw> - it's just that
479 this isn't generally a good idea so we don't provide a shortcut for it.
481 C<rwp> generates a reader like C<ro>, but also sets C<writer> to
482 C<_set_${attribute_name}> for attributes that are designed to be written
483 from inside of the class, but read-only from outside.
484 This feature comes from L<MooseX::AttributeShortcuts>.
486 C<rw> generates a normal getter/setter by defaulting C<accessor> to the
487 name of the attribute.
491 Takes a coderef which is meant to validate the attribute. Unlike L<Moose>, Moo
492 does not include a basic type system, so instead of doing C<< isa => 'Num' >>,
496 die "$_[0] is not a number!" unless looks_like_number $_[0]
499 Note that the return value is ignored, only whether the sub lives or
502 L<Sub::Quote aware|/SUB QUOTE AWARE>
504 Since L<Moo> does B<not> run the C<isa> check before C<coerce> if a coercion
505 subroutine has been supplied, C<isa> checks are not structural to your code
506 and can, if desired, be omitted on non-debug builds (although if this results
507 in an uncaught bug causing your program to break, the L<Moo> authors guarantee
508 nothing except that you get to keep both halves).
510 If you want L<MooseX::Types> style named types, look at
511 L<MooX::Types::MooseLike>.
513 To cause your C<isa> entries to be automatically mapped to named
514 L<Moose::Meta::TypeConstraint> objects (rather than the default behaviour
515 of creating an anonymous type), set:
517 $Moo::HandleMoose::TYPE_MAP{$isa_coderef} = sub {
518 require MooseX::Types::Something;
519 return MooseX::Types::Something::TypeName();
522 Note that this example is purely illustrative; anything that returns a
523 L<Moose::Meta::TypeConstraint> object or something similar enough to it to
524 make L<Moose> happy is fine.
528 Takes a coderef which is meant to coerce the attribute. The basic idea is to
529 do something like the following:
532 $_[0] % 2 ? $_[0] : $_[0] + 1
535 Note that L<Moo> will always fire your coercion: this is to permit
536 C<isa> entries to be used purely for bug trapping, whereas coercions are
537 always structural to your code. We do, however, apply any supplied C<isa>
538 check after the coercion has run to ensure that it returned a valid value.
540 L<Sub::Quote aware|/SUB QUOTE AWARE>
546 handles => 'RobotRole'
548 Where C<RobotRole> is a role (L<Moo::Role>) that defines an interface which
549 becomes the list of methods to handle.
551 Takes a list of methods
553 handles => [ qw( one two ) ]
563 Takes a coderef which will get called any time the attribute is set. This
564 includes the constructor, but not default or built values. Coderef will be
565 invoked against the object with the new value as an argument.
567 If you set this to just C<1>, it generates a trigger which calls the
568 C<_trigger_${attr_name}> method on C<$self>. This feature comes from
569 L<MooseX::AttributeShortcuts>.
571 Note that Moose also passes the old value, if any; this feature is not yet
574 L<Sub::Quote aware|/SUB QUOTE AWARE>
578 Takes a coderef which will get called with $self as its only argument
579 to populate an attribute if no value is supplied to the constructor - or
580 if the attribute is lazy, when the attribute is first retrieved if no
581 value has yet been provided.
583 If a simple scalar is provided, it will be inlined as a string. Any non-code
584 reference (hash, array) will result in an error - for that case instead use
585 a code reference that returns the desired value.
587 Note that if your default is fired during new() there is no guarantee that
588 other attributes have been populated yet so you should not rely on their
591 L<Sub::Quote aware|/SUB QUOTE AWARE>
595 Takes a method name which will return true if an attribute has a value.
597 If you set this to just C<1>, the predicate is automatically named
598 C<has_${attr_name}> if your attribute's name does not start with an
599 underscore, or C<_has_${attr_name_without_the_underscore}> if it does.
600 This feature comes from L<MooseX::AttributeShortcuts>.
604 Takes a method name which will be called to create the attribute - functions
605 exactly like default except that instead of calling
613 The following features come from L<MooseX::AttributeShortcuts>:
615 If you set this to just C<1>, the builder is automatically named
616 C<_build_${attr_name}>.
618 If you set this to a coderef or code-convertible object, that variable will be
619 installed under C<$class::_build_${attr_name}> and the builder set to the same
624 Takes a method name which will clear the attribute.
626 If you set this to just C<1>, the clearer is automatically named
627 C<clear_${attr_name}> if your attribute's name does not start with an
628 underscore, or <_clear_${attr_name_without_the_underscore}> if it does.
629 This feature comes from L<MooseX::AttributeShortcuts>.
633 B<Boolean>. Set this if you want values for the attribute to be grabbed
634 lazily. This is usually a good idea if you have a L</builder> which requires
635 another attribute to be set.
639 B<Boolean>. Set this if the attribute must be passed on instantiation.
643 The value of this attribute will be the name of the method to get the value of
644 the attribute. If you like Java style methods, you might set this to
649 The value of this attribute will be the name of the method to set the value of
650 the attribute. If you like Java style methods, you might set this to
655 B<Boolean>. Set this if you want the reference that the attribute contains to
656 be weakened; use this when circular references are possible, which will cause
661 Takes the name of the key to look for at instantiation time of the object. A
662 common use of this is to make an underscored attribute have a non-underscored
663 initialization name. C<undef> means that passing the value in on instantiation
668 Takes either a coderef or array of coderefs which is meant to transform the
669 given attributes specifications if necessary when upgrading to a Moose role or
670 class. You shouldn't need this by default, but is provided as a means of
671 possible extensibility.

696 =head1 SUB QUOTE AWARE
698 L<Sub::Quote/quote_sub> allows us to create coderefs that are "inlineable,"
699 giving us a handy, XS-free speed boost. Any option that is L<Sub::Quote>
700 aware can take advantage of this.
702 To do this, you can write
709 isa => quote_sub(q{ die "Not <3" unless $_[0] < 3 })
712 which will be inlined as
715 local @_ = ($_[0]->{foo});
716 die "Not <3" unless $_[0] < 3;
719 or to avoid localizing @_,
723 isa => quote_sub(q{ my ($val) = @_; die "Not <3" unless $val < 3 })
726 which will be inlined as
729 my ($val) = ($_[0]->{foo});
730 die "Not <3" unless $val < 3;
733 See L<Sub::Quote> for more information, including how to pass lexical
734 captures that will also be compiled into the subroutine.
736 =head1 INCOMPATIBILITIES WITH MOOSE
738 There is no built-in type system. C<isa> is verified with a coderef; if you
739 need complex types, just make a library of coderefs, or better yet, functions
740 that return quoted subs. L<MooX::Types::MooseLike> provides a similar API
741 to L<MooseX::Types::Moose> so that you can write
743 has days_to_live => (is => 'ro', isa => Int);
745 and have it work with both; it is hoped that providing only subrefs as an
746 API will encourage the use of other type systems as well, since it's
747 probably the weakest part of Moose design-wise.
749 C<initializer> is not supported in core since the author considers it to be a
750 bad idea and Moose best practices recommend avoiding it. Meanwhile C<trigger> or
751 C<coerce> are more likely to be able to fulfill your needs.
753 There is no meta object. If you need this level of complexity you wanted
754 L<Moose> - Moo succeeds at being small because it explicitly does not
755 provide a metaprotocol. However, if you load L<Moose>, then
757 Class::MOP::class_of($moo_class_or_role)
759 will return an appropriate metaclass pre-populated by L<Moo>.
761 No support for C<super>, C<override>, C<inner>, or C<augment> - the author
762 considers augment to be a bad idea, and override can be translated:
764 override foo => sub {
771 my ($orig, $self) = (shift, shift);
777 The C<dump> method is not provided by default. The author suggests loading
778 L<Devel::Dwarn> into C<main::> (via C<perl -MDevel::Dwarn ...> for example) and
779 using C<$obj-E<gt>$::Dwarn()> instead.
781 L</default> only supports coderefs and plain scalars, because passing a hash
782 or array reference as a default is almost always incorrect since the value is
783 then shared between all objects using that default.
785 C<lazy_build> is not supported; you are instead encouraged to use the
786 C<< is => 'lazy' >> option supported by L<Moo> and L<MooseX::AttributeShortcuts>.
788 C<auto_deref> is not supported since the author considers it a bad idea and
789 it has been considered best practice to avoid it for some time.
791 C<documentation> will show up in a L<Moose> metaclass created from your class
792 but is otherwise ignored. Then again, L<Moose> ignores it as well, so this
793 is arguably not an incompatibility.
795 Since C<coerce> does not require C<isa> to be defined but L<Moose> does
796 require it, the metaclass inflation for coerce alone is a trifle insane
797 and if you attempt to subtype the result will almost certainly break.
799 Handling of warnings: when you C<use Moo> we enable FATAL warnings. The nearest
800 similar invocation for L<Moose> would be:
803 use warnings FATAL => "all";
805 Additionally, L<Moo> supports a set of attribute option shortcuts intended to
806 reduce common boilerplate. The set of shortcuts is the same as in the L<Moose>
807 module L<MooseX::AttributeShortcuts> as of its version 0.009+. So if you:
812 The nearest L<Moose> invocation would be:
817 use warnings FATAL => "all";
818 use MooseX::AttributeShortcuts;
820 or, if you're inheriting from a non-Moose class,
825 use MooseX::NonMoose;
826 use warnings FATAL => "all";
827 use MooseX::AttributeShortcuts;
829 Finally, Moose requires you to call
831 __PACKAGE__->meta->make_immutable;
833 at the end of your class to get an inlined (i.e. not horribly slow)
834 constructor. Moo does it automatically the first time ->new is called
835 on your class. (C<make_immutable> is a no-op in Moo to ease migration.)
837 An extension L<MooX::late> exists to ease translating Moose packages
838 to Moo by providing a more Moose-like interface.
