316 | |||||
317 | =head1 DESCRIPTION | ||||
318 | |||||
319 | Moose is an extension of the Perl 5 object system. | ||||
320 | |||||
321 | The main goal of Moose is to make Perl 5 Object Oriented programming | ||||
322 | easier, more consistent and less tedious. With Moose you can to think | ||||
323 | more about what you want to do and less about the mechanics of OOP. | ||||
324 | |||||
325 | Additionally, Moose is built on top of L<Class::MOP>, which is a | ||||
326 | metaclass system for Perl 5. This means that Moose not only makes | ||||
327 | building normal Perl 5 objects better, but it provides the power of | ||||
328 | metaclass programming as well. | ||||
329 | |||||
330 | =head2 New to Moose? | ||||
331 | |||||
332 | If you're new to Moose, the best place to start is the | ||||
333 | L<Moose::Manual> docs, followed by the L<Moose::Cookbook>. The intro | ||||
334 | will show you what Moose is, and how it makes Perl 5 OO better. | ||||
335 | |||||
336 | The cookbook recipes on Moose basics will get you up to speed with | ||||
337 | many of Moose's features quickly. Once you have an idea of what Moose | ||||
338 | can do, you can use the API documentation to get more detail on | ||||
339 | features which interest you. | ||||
340 | |||||
341 | =head2 Moose Extensions | ||||
342 | |||||
343 | The C<MooseX::> namespace is the official place to find Moose extensions. | ||||
344 | These extensions can be found on the CPAN. The easiest way to find them | ||||
345 | is to search for them (L<http://search.cpan.org/search?query=MooseX::>), | ||||
346 | or to examine L<Task::Moose> which aims to keep an up-to-date, easily | ||||
347 | installable list of Moose extensions. | ||||
348 | |||||
349 | =head1 TRANSLATIONS | ||||
350 | |||||
351 | Much of the Moose documentation has been translated into other languages. | ||||
352 | |||||
353 | =over 4 | ||||
354 | |||||
355 | =item Japanese | ||||
356 | |||||
357 | Japanese docs can be found at L<http://perldoc.perlassociation.org/pod/Moose-Doc-JA/index.html>. The source POD files can be found in GitHub: L<http://github.com/jpa/Moose-Doc-JA> | ||||

361 | =head1 BUILDING CLASSES WITH MOOSE | ||||
362 | |||||
363 | Moose makes every attempt to provide as much convenience as possible during | ||||
364 | class construction/definition, but still stay out of your way if you want it | ||||
365 | to. Here are a few items to note when building classes with Moose. | ||||
366 | |||||
367 | Unless specified with C<extends>, any class which uses Moose will | ||||
368 | inherit from L<Moose::Object>. | ||||
369 | |||||
370 | Moose will also manage all attributes (including inherited ones) that are | ||||
371 | defined with C<has>. And (assuming you call C<new>, which is inherited from | ||||
372 | L<Moose::Object>) this includes properly initializing all instance slots, | ||||
373 | setting defaults where appropriate, and performing any type constraint checking | ||||
374 | or coercion. | ||||
375 | |||||
376 | =head1 PROVIDED METHODS | ||||
377 | |||||
378 | Moose provides a number of methods to all your classes, mostly through the | ||||
379 | inheritance of L<Moose::Object>. There is however, one exception. | ||||
380 | |||||
381 | =over 4 | ||||
382 | |||||
383 | =item B<meta> | ||||
384 | |||||
385 | This is a method which provides access to the current class's metaclass. | ||||
386 | |||||
387 | =back | ||||
388 | |||||
389 | =head1 EXPORTED FUNCTIONS | ||||
390 | |||||
391 | Moose will export a number of functions into the class's namespace which | ||||
392 | may then be used to set up the class. These functions all work directly | ||||
393 | on the current class. | ||||
394 | |||||
395 | =over 4 | ||||
396 | |||||
397 | =item B<extends (@superclasses)> | ||||
398 | |||||
399 | This function will set the superclass(es) for the current class. | ||||
400 | |||||
401 | This approach is recommended instead of C<use base>, because C<use base> | ||||
402 | actually C<push>es onto the class's C<@ISA>, whereas C<extends> will | ||||
403 | replace it. This is important to ensure that classes which do not have | ||||
404 | superclasses still properly inherit from L<Moose::Object>. | ||||
405 | |||||
406 | =item B<with (@roles)> | ||||
407 | |||||
408 | This will apply a given set of C<@roles> to the local class. | ||||
409 | |||||
410 | =item B<has $name|@$names =E<gt> %options> | ||||
411 | |||||
412 | This will install an attribute of a given C<$name> into the current class. If | ||||
413 | the first parameter is an array reference, it will create an attribute for | ||||
414 | every C<$name> in the list. The C<%options> are the same as those provided by | ||||
415 | L<Class::MOP::Attribute>, in addition to the list below which are provided by | ||||
416 | Moose (L<Moose::Meta::Attribute> to be more specific): | ||||
417 | |||||
418 | =over 4 | ||||
419 | |||||
420 | =item I<is =E<gt> 'rw'|'ro'> | ||||
421 | |||||
422 | The I<is> option accepts either I<rw> (for read/write) or I<ro> (for read | ||||
423 | only). These will create either a read/write accessor or a read-only | ||||
424 | accessor respectively, using the same name as the C<$name> of the attribute. | ||||
425 | |||||
426 | If you need more control over how your accessors are named, you can | ||||
427 | use the L<reader|Class::MOP::Attribute/reader>, | ||||
428 | L<writer|Class::MOP::Attribute/writer> and | ||||
429 | L<accessor|Class::MOP::Attribute/accessor> options inherited from | ||||
430 | L<Class::MOP::Attribute>, however if you use those, you won't need the | ||||
431 | I<is> option. | ||||
432 | |||||
433 | =item I<isa =E<gt> $type_name> | ||||
434 | |||||
435 | The I<isa> option uses Moose's type constraint facilities to set up runtime | ||||
436 | type checking for this attribute. Moose will perform the checks during class | ||||
437 | construction, and within any accessors. The C<$type_name> argument must be a | ||||
438 | string. The string may be either a class name or a type defined using | ||||
439 | Moose's type definition features. (Refer to L<Moose::Util::TypeConstraints> | ||||
440 | for information on how to define a new type, and how to retrieve type meta-data). | ||||
441 | |||||
442 | =item I<coerce =E<gt> (1|0)> | ||||
443 | |||||
444 | This will attempt to use coercion with the supplied type constraint to change | ||||
445 | the value passed into any accessors or constructors. You B<must> have supplied | ||||
446 | a type constraint in order for this to work. See L<Moose::Cookbook::Basics::Recipe5> | ||||
447 | for an example. | ||||
448 | |||||
449 | =item I<does =E<gt> $role_name> | ||||
450 | |||||
451 | This will accept the name of a role which the value stored in this attribute | ||||
452 | is expected to have consumed. | ||||
453 | |||||
454 | =item I<required =E<gt> (1|0)> | ||||
455 | |||||
456 | This marks the attribute as being required. This means a value must be | ||||
457 | supplied during class construction, I<or> the attribute must be lazy | ||||
458 | and have either a default or a builder. Note that c<required> does not | ||||
459 | say anything about the attribute's value, which can be C<undef>. | ||||
460 | |||||
461 | =item I<weak_ref =E<gt> (1|0)> | ||||
462 | |||||
463 | This will tell the class to store the value of this attribute as a weakened | ||||
464 | reference. If an attribute is a weakened reference, it B<cannot> also be | ||||
465 | coerced. | ||||
466 | |||||
467 | =item I<lazy =E<gt> (1|0)> | ||||
468 | |||||
469 | This will tell the class to not create this slot until absolutely necessary. | ||||
470 | If an attribute is marked as lazy it B<must> have a default supplied. | ||||
471 | |||||
472 | =item I<auto_deref =E<gt> (1|0)> | ||||
473 | |||||
474 | This tells the accessor to automatically dereference the value of this | ||||
475 | attribute when called in list context. The accessor will still return a | ||||
476 | reference when called in scalar context. If this behavior isn't desirable, | ||||
477 | L<Moose::Meta::Attribute::Native::Trait::Array/elements> or | ||||
478 | L<Moose::Meta::Attribute::Native::Trait::Hash/elements> may be a better | ||||
479 | choice. The I<auto_deref> option is only legal if your I<isa> option is | ||||
480 | either C<ArrayRef> or C<HashRef>. | ||||
481 | |||||
482 | =item I<trigger =E<gt> $code> | ||||
483 | |||||
484 | The I<trigger> option is a CODE reference which will be called after | ||||
485 | the value of the attribute is set. The CODE ref will be passed the | ||||
486 | instance itself and the updated value. If the attribute already had a | ||||
487 | value, this will be passed as the third value to the trigger. | ||||
488 | |||||
489 | You B<can> have a trigger on a read-only attribute. | ||||
490 | |||||
491 | B<NOTE:> Triggers will only fire when you B<assign> to the attribute, | ||||
492 | either in the constructor, or using the writer. Default and built values will | ||||
493 | B<not> cause the trigger to be fired. | ||||
494 | |||||
495 | =item I<handles =E<gt> ARRAY | HASH | REGEXP | ROLE | DUCKTYPE | CODE> | ||||
496 | |||||
497 | The I<handles> option provides Moose classes with automated delegation features. | ||||
498 | This is a pretty complex and powerful option. It accepts many different option | ||||
499 | formats, each with its own benefits and drawbacks. | ||||
500 | |||||
501 | B<NOTE:> The class being delegated to does not need to be a Moose based class, | ||||
502 | which is why this feature is especially useful when wrapping non-Moose classes. | ||||
503 | |||||
504 | All I<handles> option formats share the following traits: | ||||
505 | |||||
506 | You cannot override a locally defined method with a delegated method; an | ||||
507 | exception will be thrown if you try. That is to say, if you define C<foo> in | ||||
508 | your class, you cannot override it with a delegated C<foo>. This is almost never | ||||
509 | something you would want to do, and if it is, you should do it by hand and not | ||||
510 | use Moose. | ||||
511 | |||||
512 | You cannot override any of the methods found in Moose::Object, or the C<BUILD> | ||||
513 | and C<DEMOLISH> methods. These will not throw an exception, but will silently | ||||
514 | move on to the next method in the list. My reasoning for this is that you would | ||||
515 | almost never want to do this, since it usually breaks your class. As with | ||||
516 | overriding locally defined methods, if you do want to do this, you should do it | ||||
517 | manually, not with Moose. | ||||
518 | |||||
519 | You do not I<need> to have a reader (or accessor) for the attribute in order | ||||
520 | to delegate to it. Moose will create a means of accessing the value for you, | ||||
521 | however this will be several times B<less> efficient then if you had given | ||||
522 | the attribute a reader (or accessor) to use. | ||||
523 | |||||
524 | Below is the documentation for each option format: | ||||
525 | |||||
526 | =over 4 | ||||
527 | |||||
528 | =item C<ARRAY> | ||||
529 | |||||
530 | This is the most common usage for I<handles>. You basically pass a list of | ||||
531 | method names to be delegated, and Moose will install a delegation method | ||||
532 | for each one. | ||||
533 | |||||
534 | =item C<HASH> | ||||
535 | |||||
536 | This is the second most common usage for I<handles>. Instead of a list of | ||||
537 | method names, you pass a HASH ref where each key is the method name you | ||||
538 | want installed locally, and its value is the name of the original method | ||||
539 | in the class being delegated to. | ||||
540 | |||||
541 | This can be very useful for recursive classes like trees. Here is a | ||||
542 | quick example (soon to be expanded into a Moose::Cookbook recipe): | ||||
543 | |||||
544 | package Tree; | ||||
545 | use Moose; | ||||
546 | |||||
547 | has 'node' => (is => 'rw', isa => 'Any'); | ||||
548 | |||||
549 | has 'children' => ( | ||||
550 | is => 'ro', | ||||
551 | isa => 'ArrayRef', | ||||
552 | default => sub { [] } | ||||
553 | ); | ||||
554 | |||||
555 | has 'parent' => ( | ||||
556 | is => 'rw', | ||||
557 | isa => 'Tree', | ||||
558 | weak_ref => 1, | ||||
559 | handles => { | ||||
560 | parent_node => 'node', | ||||
561 | siblings => 'children', | ||||
562 | } | ||||
563 | ); | ||||
564 | |||||
565 | In this example, the Tree package gets C<parent_node> and C<siblings> methods, | ||||
566 | which delegate to the C<node> and C<children> methods (respectively) of the Tree | ||||
567 | instance stored in the C<parent> slot. | ||||
568 | |||||
569 | You may also use an array reference to curry arguments to the original method. | ||||
570 | |||||
571 | has 'thing' => ( | ||||
572 | ... | ||||
573 | handles => { set_foo => [ set => 'foo' ] }, | ||||
574 | ); | ||||
575 | |||||
576 | # $self->set_foo(...) calls $self->thing->set('foo', ...) | ||||
577 | |||||
578 | The first element of the array reference is the original method name, and the | ||||
579 | rest is a list of curried arguments. | ||||
580 | |||||
581 | =item C<REGEXP> | ||||
582 | |||||
583 | The regexp option works very similar to the ARRAY option, except that it builds | ||||
584 | the list of methods for you. It starts by collecting all possible methods of the | ||||
585 | class being delegated to, then filters that list using the regexp supplied here. | ||||
586 | |||||
587 | B<NOTE:> An I<isa> option is required when using the regexp option format. This | ||||
588 | is so that we can determine (at compile time) the method list from the class. | ||||
589 | Without an I<isa> this is just not possible. | ||||
590 | |||||
591 | =item C<ROLE> | ||||
592 | |||||
593 | With the role option, you specify the name of a role whose "interface" then | ||||
594 | becomes the list of methods to handle. The "interface" can be defined as; the | ||||
595 | methods of the role and any required methods of the role. It should be noted | ||||
596 | that this does B<not> include any method modifiers or generated attribute | ||||
597 | methods (which is consistent with role composition). | ||||
598 | |||||
599 | =item C<DUCKTYPE> | ||||
600 | |||||
601 | With the duck type option, you pass a duck type object whose "interface" then | ||||
602 | becomes the list of methods to handle. The "interface" can be defined as; the | ||||
603 | list of methods passed to C<duck_type> to create a duck type object. For more | ||||
604 | information on C<duck_type> please check | ||||
605 | L<Moose::Util::TypeConstraints>. | ||||
606 | |||||
607 | =item C<CODE> | ||||
608 | |||||
609 | This is the option to use when you really want to do something funky. You should | ||||
610 | only use it if you really know what you are doing, as it involves manual | ||||
611 | metaclass twiddling. | ||||
612 | |||||
613 | This takes a code reference, which should expect two arguments. The first is the | ||||
614 | attribute meta-object this I<handles> is attached to. The second is the | ||||
615 | metaclass of the class being delegated to. It expects you to return a hash (not | ||||
616 | a HASH ref) of the methods you want mapped. | ||||
617 | |||||
618 | =back | ||||
619 | |||||
620 | =item I<metaclass =E<gt> $metaclass_name> | ||||
621 | |||||
622 | This tells the class to use a custom attribute metaclass for this particular | ||||
623 | attribute. Custom attribute metaclasses are useful for extending the | ||||
624 | capabilities of the I<has> keyword: they are the simplest way to extend the MOP, | ||||
625 | but they are still a fairly advanced topic and too much to cover here, see | ||||
626 | L<Moose::Cookbook::Meta::Recipe1> for more information. | ||||
627 | |||||
628 | See L<Metaclass and Trait Name Resolution> for details on how a metaclass name | ||||
629 | is resolved to a class name. | ||||
630 | |||||
631 | =item I<traits =E<gt> [ @role_names ]> | ||||
632 | |||||
633 | This tells Moose to take the list of C<@role_names> and apply them to the | ||||
634 | attribute meta-object. This is very similar to the I<metaclass> option, but | ||||
635 | allows you to use more than one extension at a time. | ||||
636 | |||||
637 | See L<Metaclass and Trait Name Resolution> for details on how a trait name is | ||||
638 | resolved to a role name. | ||||
639 | |||||
640 | Also see L<Moose::Cookbook::Meta::Recipe3> for a metaclass trait | ||||
641 | example. | ||||
642 | |||||
643 | =item I<builder> => Str | ||||
644 | |||||
645 | The value of this key is the name of the method that will be called to | ||||
646 | obtain the value used to initialize the attribute. See the L<builder | ||||
647 | option docs in Class::MOP::Attribute|Class::MOP::Attribute/builder> | ||||
648 | and/or L<Moose::Cookbook::Basics::Recipe8> for more information. | ||||
649 | |||||
650 | =item I<default> => SCALAR | CODE | ||||
651 | |||||
652 | The value of this key is the default value which will initialize the attribute. | ||||
653 | |||||
654 | NOTE: If the value is a simple scalar (string or number), then it can | ||||
655 | be just passed as is. However, if you wish to initialize it with a | ||||
656 | HASH or ARRAY ref, then you need to wrap that inside a CODE reference. | ||||
657 | See the L<default option docs in | ||||
658 | Class::MOP::Attribute|Class::MOP::Attribute/default> for more | ||||
659 | information. | ||||
660 | |||||
661 | =item I<clearer> => Str | ||||
662 | |||||
663 | Creates a method allowing you to clear the value, see the L<clearer option | ||||
664 | docs in Class::MOP::Attribute|Class::MOP::Attribute/clearer> for more | ||||
665 | information. | ||||
666 | |||||
667 | =item I<predicate> => Str | ||||
668 | |||||
669 | Creates a method to perform a basic test to see if a value has been set in the | ||||
670 | attribute, see the L<predicate option docs in | ||||
671 | Class::MOP::Attribute|Class::MOP::Attribute/predicate> for more information. | ||||
672 | |||||
673 | =item I<lazy_build> => (0|1) | ||||
674 | |||||
675 | Automatically define lazy => 1 as well as builder => "_build_$attr", clearer => | ||||
676 | "clear_$attr', predicate => 'has_$attr' unless they are already defined. | ||||
677 | |||||
678 | =item I<initializer> => Str | ||||
679 | |||||
680 | This may be a method name (referring to a method on the class with | ||||
681 | this attribute) or a CODE ref. The initializer is used to set the | ||||
682 | attribute value on an instance when the attribute is set during | ||||
683 | instance initialization (but not when the value is being assigned | ||||
684 | to). See the L<initializer option docs in | ||||
685 | Class::MOP::Attribute|Class::MOP::Attribute/initializer> for more | ||||
686 | information. | ||||
687 | |||||
688 | =item I<documentation> => $string | ||||
689 | |||||
690 | An arbitrary string that can be retrieved later by calling C<< | ||||
691 | $attr->documentation >>. | ||||
692 | |||||
693 | |||||
694 | |||||
695 | =back | ||||
696 | |||||
697 | =item B<has +$name =E<gt> %options> | ||||
698 | |||||
699 | This is variation on the normal attribute creator C<has> which allows you to | ||||
700 | clone and extend an attribute from a superclass or from a role. Here is an | ||||
701 | example of the superclass usage: | ||||
702 | |||||
703 | package Foo; | ||||
704 | use Moose; | ||||
705 | |||||
706 | has 'message' => ( | ||||
707 | is => 'rw', | ||||
708 | isa => 'Str', | ||||
709 | default => 'Hello, I am a Foo' | ||||
710 | ); | ||||
711 | |||||
712 | package My::Foo; | ||||
713 | use Moose; | ||||
714 | |||||
715 | extends 'Foo'; | ||||
716 | |||||
717 | has '+message' => (default => 'Hello I am My::Foo'); | ||||
718 | |||||
719 | What is happening here is that B<My::Foo> is cloning the C<message> attribute | ||||
720 | from its parent class B<Foo>, retaining the C<is =E<gt> 'rw'> and C<isa =E<gt> | ||||
721 | 'Str'> characteristics, but changing the value in C<default>. | ||||
722 | |||||
723 | Here is another example, but within the context of a role: | ||||
724 | |||||
725 | package Foo::Role; | ||||
726 | use Moose::Role; | ||||
727 | |||||
728 | has 'message' => ( | ||||
729 | is => 'rw', | ||||
730 | isa => 'Str', | ||||
731 | default => 'Hello, I am a Foo' | ||||
732 | ); | ||||
733 | |||||
734 | package My::Foo; | ||||
735 | use Moose; | ||||
736 | |||||
737 | with 'Foo::Role'; | ||||
738 | |||||
739 | has '+message' => (default => 'Hello I am My::Foo'); | ||||
740 | |||||
741 | In this case, we are basically taking the attribute which the role supplied | ||||
742 | and altering it within the bounds of this feature. | ||||
743 | |||||
744 | Note that you can only extend an attribute from either a superclass or a role, | ||||
745 | you cannot extend an attribute in a role that composes over an attribute from | ||||
746 | another role. | ||||
747 | |||||
748 | Aside from where the attributes come from (one from superclass, the other | ||||
749 | from a role), this feature works exactly the same. This feature is restricted | ||||
750 | somewhat, so as to try and force at least I<some> sanity into it. You are only | ||||
751 | allowed to change the following attributes: | ||||
752 | |||||
753 | =over 4 | ||||
754 | |||||
755 | =item I<default> | ||||
756 | |||||
757 | Change the default value of an attribute. | ||||
758 | |||||
759 | =item I<coerce> | ||||
760 | |||||
761 | Change whether the attribute attempts to coerce a value passed to it. | ||||
762 | |||||
763 | =item I<required> | ||||
764 | |||||
765 | Change if the attribute is required to have a value. | ||||
766 | |||||
767 | =item I<documentation> | ||||
768 | |||||
769 | Change the documentation string associated with the attribute. | ||||
770 | |||||
771 | =item I<lazy> | ||||
772 | |||||
773 | Change if the attribute lazily initializes the slot. | ||||
774 | |||||
775 | =item I<isa> | ||||
776 | |||||
777 | You I<are> allowed to change the type without restriction. | ||||
778 | |||||
779 | It is recommended that you use this freedom with caution. We used to | ||||
780 | only allow for extension only if the type was a subtype of the parent's | ||||
781 | type, but we felt that was too restrictive and is better left as a | ||||
782 | policy decision. | ||||
783 | |||||
784 | =item I<handles> | ||||
785 | |||||
786 | You are allowed to B<add> a new C<handles> definition, but you are B<not> | ||||
787 | allowed to I<change> one. | ||||
788 | |||||
789 | =item I<builder> | ||||
790 | |||||
791 | You are allowed to B<add> a new C<builder> definition, but you are B<not> | ||||
792 | allowed to I<change> one. | ||||
793 | |||||
794 | =item I<metaclass> | ||||
795 | |||||
796 | You are allowed to B<add> a new C<metaclass> definition, but you are | ||||
797 | B<not> allowed to I<change> one. | ||||
798 | |||||
799 | =item I<traits> | ||||
800 | |||||
801 | You are allowed to B<add> additional traits to the C<traits> definition. | ||||
802 | These traits will be composed into the attribute, but preexisting traits | ||||
803 | B<are not> overridden, or removed. | ||||
804 | |||||
805 | =back | ||||
806 | |||||
807 | =item B<before $name|@names =E<gt> sub { ... }> | ||||
808 | |||||
809 | =item B<after $name|@names =E<gt> sub { ... }> | ||||
810 | |||||
811 | =item B<around $name|@names =E<gt> sub { ... }> | ||||
812 | |||||
813 | These three items are syntactic sugar for the before, after, and around method | ||||
814 | modifier features that L<Class::MOP> provides. More information on these may be | ||||
815 | found in L<Moose::Manual::MethodModifiers> and the | ||||
816 | L<Class::MOP::Class documentation|Class::MOP::Class/"Method Modifiers">. | ||||
817 | |||||
818 | =item B<super> | ||||
819 | |||||
820 | The keyword C<super> is a no-op when called outside of an C<override> method. In | ||||
821 | the context of an C<override> method, it will call the next most appropriate | ||||
822 | superclass method with the same arguments as the original method. | ||||
823 | |||||
824 | =item B<override ($name, &sub)> | ||||
825 | |||||
826 | An C<override> method is a way of explicitly saying "I am overriding this | ||||
827 | method from my superclass". You can call C<super> within this method, and | ||||
828 | it will work as expected. The same thing I<can> be accomplished with a normal | ||||
829 | method call and the C<SUPER::> pseudo-package; it is really your choice. | ||||
830 | |||||
831 | =item B<inner> | ||||
832 | |||||
833 | The keyword C<inner>, much like C<super>, is a no-op outside of the context of | ||||
834 | an C<augment> method. You can think of C<inner> as being the inverse of | ||||
835 | C<super>; the details of how C<inner> and C<augment> work is best described in | ||||
836 | the L<Moose::Cookbook::Basics::Recipe6>. | ||||
837 | |||||
838 | =item B<augment ($name, &sub)> | ||||
839 | |||||
840 | An C<augment> method, is a way of explicitly saying "I am augmenting this | ||||
841 | method from my superclass". Once again, the details of how C<inner> and | ||||
842 | C<augment> work is best described in the L<Moose::Cookbook::Basics::Recipe6>. | ||||
843 | |||||
844 | =item B<confess> | ||||
845 | |||||
846 | This is the C<Carp::confess> function, and exported here because I use it | ||||
847 | all the time. | ||||
848 | |||||
849 | =item B<blessed> | ||||
850 | |||||
851 | This is the C<Scalar::Util::blessed> function, it is exported here because I | ||||
852 | use it all the time. It is highly recommended that this is used instead of | ||||
853 | C<ref> anywhere you need to test for an object's class name. | ||||
854 | |||||
855 | =back | ||||
856 | |||||
857 | =head1 METACLASS | ||||
858 | |||||
859 | When you use Moose, you can specify which metaclass to use: | ||||
860 | |||||
861 | use Moose -metaclass => 'My::Meta::Class'; | ||||
862 | |||||
863 | You can also specify traits which will be applied to your metaclass: | ||||
864 | |||||
865 | use Moose -traits => 'My::Trait'; | ||||
866 | |||||
867 | This is very similar to the attribute traits feature. When you do | ||||
868 | this, your class's C<meta> object will have the specified traits | ||||
869 | applied to it. See L<Metaclass and Trait Name Resolution> for more | ||||
870 | details. | ||||
871 | |||||
872 | =head2 Metaclass and Trait Name Resolution | ||||
873 | |||||
874 | By default, when given a trait name, Moose simply tries to load a | ||||
875 | class of the same name. If such a class does not exist, it then looks | ||||
876 | for for a class matching | ||||
877 | B<Moose::Meta::$type::Custom::Trait::$trait_name>. The C<$type> | ||||
878 | variable here will be one of B<Attribute> or B<Class>, depending on | ||||
879 | what the trait is being applied to. | ||||
880 | |||||
881 | If a class with this long name exists, Moose checks to see if it has | ||||
882 | the method C<register_implementation>. This method is expected to | ||||
883 | return the I<real> class name of the trait. If there is no | ||||
884 | C<register_implementation> method, it will fall back to using | ||||
885 | B<Moose::Meta::$type::Custom::Trait::$trait> as the trait name. | ||||
886 | |||||
887 | The lookup method for metaclasses is the same, except that it looks | ||||
888 | for a class matching B<Moose::Meta::$type::Custom::$metaclass_name>. | ||||
889 | |||||
890 | If all this is confusing, take a look at | ||||
891 | L<Moose::Cookbook::Meta::Recipe3>, which demonstrates how to create an | ||||
892 | attribute trait. | ||||
893 | |||||
894 | =head1 UNIMPORTING FUNCTIONS | ||||
895 | |||||
896 | =head2 B<unimport> | ||||
897 | |||||
898 | Moose offers a way to remove the keywords it exports, through the C<unimport> | ||||
899 | method. You simply have to say C<no Moose> at the bottom of your code for this | ||||
900 | to work. Here is an example: | ||||
901 | |||||
902 | package Person; | ||||
903 | use Moose; | ||||
904 | |||||
905 | has 'first_name' => (is => 'rw', isa => 'Str'); | ||||
906 | has 'last_name' => (is => 'rw', isa => 'Str'); | ||||
907 | |||||
908 | sub full_name { | ||||
909 | my $self = shift; | ||||
910 | $self->first_name . ' ' . $self->last_name | ||||
911 | } | ||||
912 | |||||
913 | no Moose; # keywords are removed from the Person package | ||||
914 | |||||
915 | =head1 EXTENDING AND EMBEDDING MOOSE | ||||
916 | |||||
917 | To learn more about extending Moose, we recommend checking out the | ||||
918 | "Extending" recipes in the L<Moose::Cookbook>, starting with | ||||
919 | L<Moose::Cookbook::Extending::Recipe1>, which provides an overview of | ||||
920 | all the different ways you might extend Moose. | ||||
921 | |||||
922 | =head2 B<< Moose->init_meta(for_class => $class, base_class => $baseclass, metaclass => $metaclass) >> | ||||
923 | |||||
924 | The C<init_meta> method sets up the metaclass object for the class | ||||
925 | specified by C<for_class>. This method injects a a C<meta> accessor | ||||
926 | into the class so you can get at this object. It also sets the class's | ||||
927 | superclass to C<base_class>, with L<Moose::Object> as the default. | ||||
928 | |||||
929 | C<init_meta> returns the metaclass object for C<$class>. | ||||
930 | |||||
931 | You can specify an alternate metaclass with the C<metaclass> option. | ||||
932 | |||||
933 | For more detail on this topic, see L<Moose::Cookbook::Extending::Recipe2>. | ||||
934 | |||||
935 | This method used to be documented as a function which accepted | ||||
936 | positional parameters. This calling style will still work for | ||||
937 | backwards compatibility, but is deprecated. | ||||
938 | |||||
939 | =head2 B<import> | ||||
940 | |||||
941 | Moose's C<import> method supports the L<Sub::Exporter> form of C<{into =E<gt> $pkg}> | ||||
942 | and C<{into_level =E<gt> 1}>. | ||||
943 | |||||
944 | B<NOTE>: Doing this is more or less deprecated. Use L<Moose::Exporter> | ||||
945 | instead, which lets you stack multiple C<Moose.pm>-alike modules | ||||
946 | sanely. It handles getting the exported functions into the right place | ||||
947 | for you. | ||||
948 | |||||
949 | =head2 B<throw_error> | ||||
950 | |||||

955 | Metaclass compatibility is a thorny subject. You should start by | ||||
956 | reading the "About Metaclass compatibility" section in the | ||||
957 | C<Class::MOP> docs. | ||||
958 | |||||
959 | Moose will attempt to resolve a few cases of metaclass incompatibility | ||||
960 | when you set the superclasses for a class, unlike C<Class::MOP>, which | ||||
961 | simply dies if the metaclasses are incompatible. | ||||
962 | |||||
963 | In actuality, Moose fixes incompatibility for I<all> of a class's | ||||
964 | metaclasses, not just the class metaclass. That includes the instance | ||||
965 | metaclass, attribute metaclass, as well as its constructor class and | ||||
966 | destructor class. However, for simplicity this discussion will just | ||||
967 | refer to "metaclass", meaning the class metaclass, most of the time. | ||||
968 | |||||
969 | Moose has two algorithms for fixing metaclass incompatibility. | ||||
970 | |||||
971 | The first algorithm is very simple. If all the metaclass for the | ||||
972 | parent is a I<subclass> of the child's metaclass, then we simply | ||||
973 | replace the child's metaclass with the parent's. | ||||
974 | |||||
975 | The second algorithm is more complicated. It tries to determine if the | ||||
976 | metaclasses only "differ by roles". This means that the parent and | ||||
977 | child's metaclass share a common ancestor in their respective | ||||
978 | hierarchies, and that the subclasses under the common ancestor are | ||||
979 | only different because of role applications. This case is actually | ||||
980 | fairly common when you mix and match various C<MooseX::*> modules, | ||||
981 | many of which apply roles to the metaclass. | ||||
982 | |||||
983 | If the parent and child do differ by roles, Moose replaces the | ||||
984 | metaclass in the child with a newly created metaclass. This metaclass | ||||
985 | is a subclass of the parent's metaclass, does all of the roles that | ||||
986 | the child's metaclass did before being replaced. Effectively, this | ||||
987 | means the new metaclass does all of the roles done by both the | ||||
988 | parent's and child's original metaclasses. | ||||
989 | |||||
990 | Ultimately, this is all transparent to you except in the case of an | ||||
991 | unresolvable conflict. | ||||
992 | |||||
993 | =head2 The MooseX:: namespace | ||||
994 | |||||
995 | Generally if you're writing an extension I<for> Moose itself you'll want | ||||
996 | to put your extension in the C<MooseX::> namespace. This namespace is | ||||
997 | specifically for extensions that make Moose better or different in some | ||||
998 | fundamental way. It is traditionally B<not> for a package that just happens | ||||
999 | to use Moose. This namespace follows from the examples of the C<LWPx::> | ||||
1000 | and C<DBIx::> namespaces that perform the same function for C<LWP> and C<DBI> | ||||
1001 | respectively. | ||||

1007 | =item * | ||||
1008 | |||||
1009 | It should be noted that C<super> and C<inner> B<cannot> be used in the same | ||||
1010 | method. However, they may be combined within the same class hierarchy; see | ||||
1011 | F<t/014_override_augment_inner_super.t> for an example. | ||||
1012 | |||||
1013 | The reason for this is that C<super> is only valid within a method | ||||
1014 | with the C<override> modifier, and C<inner> will never be valid within an | ||||
1015 | C<override> method. In fact, C<augment> will skip over any C<override> methods | ||||
1016 | when searching for its appropriate C<inner>. | ||||
1017 | |||||
1018 | This might seem like a restriction, but I am of the opinion that keeping these | ||||
1019 | two features separate (yet interoperable) actually makes them easy to use, since | ||||
1020 | their behavior is then easier to predict. Time will tell whether I am right or | ||||
1021 | not (UPDATE: so far so good). | ||||

1025 | =head1 GETTING HELP | ||||
1026 | |||||
1027 | We offer both a mailing list and a very active IRC channel. | ||||
1028 | |||||
1029 | The mailing list is L<moose@perl.org>. You must be subscribed to send | ||||
1030 | a message. To subscribe, send an empty message to | ||||
1031 | L<moose-subscribe@perl.org> | ||||
1032 | |||||
1033 | You can also visit us at C<#moose> on L<irc://irc.perl.org/#moose> | ||||
1034 | This channel is quite active, and questions at all levels (on Moose-related | ||||
1035 | topics ;) are welcome. | ||||
1036 | |||||

1041 | =item I blame Sam Vilain for introducing me to the insanity that is meta-models. | ||||
1042 | |||||
1043 | =item I blame Audrey Tang for then encouraging my meta-model habit in #perl6. | ||||
1044 | |||||
1045 | =item Without Yuval "nothingmuch" Kogman this module would not be possible, | ||||
1046 | and it certainly wouldn't have this name ;P | ||||
1047 | |||||
1048 | =item The basis of the TypeContraints module was Rob Kinyon's idea | ||||
1049 | originally, I just ran with it. | ||||

1105 | =head1 BUGS | ||||
1106 | |||||
1107 | All complex software has bugs lurking in it, and this module is no | ||||
1108 | exception. | ||||
1109 | |||||
1110 | Please report any bugs to C<bug-moose@rt.cpan.org>, or through the web | ||||
1111 | interface at L<http://rt.cpan.org>. | ||||
1112 | |||||
1113 | You can also discuss feature requests or possible bugs on the Moose mailing | ||||
1114 | list (moose@perl.org) or on IRC at L<irc://irc.perl.org/#moose>. | ||||
1115 | |||||
1116 | =head1 FEATURE REQUESTS | ||||
1117 | |||||
1118 | We are very strict about what features we add to the Moose core, especially | ||||
1119 | the user-visible features. Instead we have made sure that the underlying | ||||
1120 | meta-system of Moose is as extensible as possible so that you can add your | ||||
1121 | own features easily. | ||||
1122 | |||||
1123 | That said, occasionally there is a feature needed in the meta-system | ||||
1124 | to support your planned extension, in which case you should either | ||||
1125 | email the mailing list (moose@perl.org) or join us on IRC at | ||||
1126 | L<irc://irc.perl.org/#moose> to discuss. The | ||||
1127 | L<Moose::Manual::Contributing> has more detail about how and when you | ||||
1128 | can contribute. | ||||
1129 | |||||
1130 | =head1 AUTHOR | ||||
1131 | |||||
1132 | Moose is an open project, there are at this point dozens of people who have | ||||
1133 | contributed, and can contribute. If you have added anything to the Moose | ||||
1134 | project you have a commit bit on this file and can add your name to the list. | ||||
1135 | |||||
1136 | =head2 CABAL | ||||
1137 | |||||
1138 | However there are only a few people with the rights to release a new version | ||||
1139 | of Moose. The Moose Cabal are the people to go to with questions regarding | ||||
1140 | the wider purview of Moose, and help out maintaining not just the code | ||||
1141 | but the community as well. | ||||
