291 | =head1 DESCRIPTION |
292 | |
26fbace8 |
293 | Moose is an extension of the Perl 5 object system. |
e522431d |
294 | |
9b9da6f1 |
295 | The main goal of Moose is to make Perl 5 Object Oriented programming |
296 | easier, more consistent and less tedious. With Moose you can to think |
6f894f30 |
297 | more about what you want to do and less about the mechanics of OOP. |
fcd84ca9 |
298 | |
6f894f30 |
299 | Additionally, Moose is built on top of L<Class::MOP>, which is a |
300 | metaclass system for Perl 5. This means that Moose not only makes |
301 | building normal Perl 5 objects better, but it provides the power of |
302 | metaclass programming as well. |

304 | =head2 New to Moose? |
305 | |
6f894f30 |
306 | If you're new to Moose, the best place to start is the L<Moose::Intro> |
307 | docs, followed by the L<Moose::Cookbook>. The intro will show you what |
308 | Moose is, and how it makes Perl 5 OO better. |
309 | |
310 | The cookbook recipes on Moose basics will get you up to speed with |
311 | many of Moose's features quickly. Once you have an idea of what Moose |
312 | can do, you can use the API documentation to get more detail on |
313 | features which interest you. |

315 | =head2 Moose Extensions |
316 | |
12aed9a0 |
317 | The C<MooseX::> namespace is the official place to find Moose extensions. |
318 | These extensions can be found on the CPAN. The easiest way to find them |
319 | is to search for them (L<http://search.cpan.org/search?query=MooseX::>), |
320 | or to examine L<Task::Moose> which aims to keep an up-to-date, easily |
321 | installable list of Moose extensions. |
28669f89 |
322 | |
6ba6d68c |
323 | =head1 BUILDING CLASSES WITH MOOSE |
324 | |
68efb014 |
325 | Moose makes every attempt to provide as much convenience as possible during |
326 | class construction/definition, but still stay out of your way if you want it |
327 | to. Here are a few items to note when building classes with Moose. |
6ba6d68c |
328 | |
26fbace8 |
329 | Unless specified with C<extends>, any class which uses Moose will |
6ba6d68c |
330 | inherit from L<Moose::Object>. |
331 | |
1cd45431 |
332 | Moose will also manage all attributes (including inherited ones) that are |
333 | defined with C<has>. And (assuming you call C<new>, which is inherited from |
334 | L<Moose::Object>) this includes properly initializing all instance slots, |
335 | setting defaults where appropriate, and performing any type constraint checking |
336 | or coercion. |
6ba6d68c |
337 | |
004222dc |
338 | =head1 PROVIDED METHODS |
6ba6d68c |
339 | |
004222dc |
340 | Moose provides a number of methods to all your classes, mostly through the |
341 | inheritance of L<Moose::Object>. There is however, one exception. |
6ba6d68c |
342 | |
343 | =over 4 |
344 | |
345 | =item B<meta> |
346 | |
347 | This is a method which provides access to the current class's metaclass. |
348 | |
004222dc |
349 | =back |
350 | |
351 | =head1 EXPORTED FUNCTIONS |
352 | |
353 | Moose will export a number of functions into the class's namespace which |
354 | may then be used to set up the class. These functions all work directly |
355 | on the current class. |
356 | |
357 | =over 4 |
358 | |
6ba6d68c |
359 | =item B<extends (@superclasses)> |
360 | |
361 | This function will set the superclass(es) for the current class. |
362 | |
26fbace8 |
363 | This approach is recommended instead of C<use base>, because C<use base> |
364 | actually C<push>es onto the class's C<@ISA>, whereas C<extends> will |
365 | replace it. This is important to ensure that classes which do not have |
68efb014 |
366 | superclasses still properly inherit from L<Moose::Object>. |
6ba6d68c |
367 | |
43d599e5 |
368 | =item B<with (@roles)> |
e9ec68d6 |
369 | |
004222dc |
370 | This will apply a given set of C<@roles> to the local class. |
e9ec68d6 |
371 | |
b4291ab4 |
372 | =item B<has $name|@$names =E<gt> %options> |
6ba6d68c |
373 | |
b4291ab4 |
374 | This will install an attribute of a given C<$name> into the current class. If |
375 | the first parameter is an array reference, it will create an attribute for |
376 | every C<$name> in the list. The C<%options> are the same as those provided by |
377 | L<Class::MOP::Attribute>, in addition to the list below which are provided by |
378 | Moose (L<Moose::Meta::Attribute> to be more specific): |
6ba6d68c |
379 | |
380 | =over 4 |
381 | |
076c81ed |
382 | =item I<is =E<gt> 'rw'|'ro'> |
6ba6d68c |
383 | |
26fbace8 |
384 | The I<is> option accepts either I<rw> (for read/write) or I<ro> (for read |
385 | only). These will create either a read/write accessor or a read-only |
6ba6d68c |
386 | accessor respectively, using the same name as the C<$name> of the attribute. |
387 | |
1b46b845 |
388 | If you need more control over how your accessors are named, you can |
389 | use the L<reader|Class::MOP::Attribute/reader>, |
390 | L<writer|Class::MOP::Attribute/writer> and |
391 | L<accessor|Class::MOP::Attribute/accessor> options inherited from |
392 | L<Class::MOP::Attribute>, however if you use those, you won't need the |
393 | I<is> option. |
6ba6d68c |
394 | |
076c81ed |
395 | =item I<isa =E<gt> $type_name> |
6ba6d68c |
396 | |
26fbace8 |
397 | The I<isa> option uses Moose's type constraint facilities to set up runtime |
398 | type checking for this attribute. Moose will perform the checks during class |
399 | construction, and within any accessors. The C<$type_name> argument must be a |
400 | string. The string may be either a class name or a type defined using |
9cca2e9e |
401 | Moose's type definition features. (Refer to L<Moose::Util::TypeConstraints> |
c2a69ef1 |
402 | for information on how to define a new type, and how to retrieve type meta-data). |
6ba6d68c |
403 | |
daea75c9 |
404 | =item I<coerce =E<gt> (1|0)> |
405 | |
26fbace8 |
406 | This will attempt to use coercion with the supplied type constraint to change |
407 | the value passed into any accessors or constructors. You B<must> have supplied |
5cfe3805 |
408 | a type constraint in order for this to work. See L<Moose::Cookbook::Basics::Recipe5> |
1cd45431 |
409 | for an example. |
daea75c9 |
410 | |
411 | =item I<does =E<gt> $role_name> |
412 | |
26fbace8 |
413 | This will accept the name of a role which the value stored in this attribute |
daea75c9 |
414 | is expected to have consumed. |
415 | |
416 | =item I<required =E<gt> (1|0)> |
417 | |
26fbace8 |
418 | This marks the attribute as being required. This means a I<defined> value must be |
419 | supplied during class construction, and the attribute may never be set to |
420 | C<undef> with an accessor. |
daea75c9 |
421 | |
422 | =item I<weak_ref =E<gt> (1|0)> |
423 | |
68efb014 |
424 | This will tell the class to store the value of this attribute as a weakened |
425 | reference. If an attribute is a weakened reference, it B<cannot> also be |
426 | coerced. |
daea75c9 |
427 | |
428 | =item I<lazy =E<gt> (1|0)> |
429 | |
26fbace8 |
430 | This will tell the class to not create this slot until absolutely necessary. |
daea75c9 |
431 | If an attribute is marked as lazy it B<must> have a default supplied. |
432 | |
9e93dd19 |
433 | =item I<auto_deref =E<gt> (1|0)> |
434 | |
26fbace8 |
435 | This tells the accessor whether to automatically dereference the value returned. |
1cd45431 |
436 | This is only legal if your C<isa> option is either C<ArrayRef> or C<HashRef>. |
9e93dd19 |
437 | |
65e14c86 |
438 | =item I<trigger =E<gt> $code> |
439 | |
440 | The I<trigger> option is a CODE reference which will be called after the value of |
441 | the attribute is set. The CODE ref will be passed the instance itself, the |
442 | updated value and the attribute meta-object (this is for more advanced fiddling |
443 | and can typically be ignored). You B<cannot> have a trigger on a read-only |
010997ca |
444 | attribute. |
445 | |
446 | B<NOTE:> Triggers will only fire when you B<assign> to the attribute, |
447 | either in the constructor, or using the writer. Default and built values will |
448 | B<not> cause the trigger to be fired. |

450 | =item I<handles =E<gt> ARRAY | HASH | REGEXP | ROLE | CODE> |
2c0cbef7 |
451 | |
26fbace8 |
452 | The I<handles> option provides Moose classes with automated delegation features. |
453 | This is a pretty complex and powerful option. It accepts many different option |
454 | formats, each with its own benefits and drawbacks. |
38e3283b |
455 | |
1cd45431 |
456 | B<NOTE:> The class being delegated to does not need to be a Moose based class, |
457 | which is why this feature is especially useful when wrapping non-Moose classes. |
38e3283b |
458 | |
1cd45431 |
459 | All I<handles> option formats share the following traits: |
38e3283b |
460 | |
1cd45431 |
461 | You cannot override a locally defined method with a delegated method; an |
462 | exception will be thrown if you try. That is to say, if you define C<foo> in |
463 | your class, you cannot override it with a delegated C<foo>. This is almost never |
464 | something you would want to do, and if it is, you should do it by hand and not |
465 | use Moose. |
38e3283b |
466 | |
1cd45431 |
467 | You cannot override any of the methods found in Moose::Object, or the C<BUILD> |
468 | and C<DEMOLISH> methods. These will not throw an exception, but will silently |
469 | move on to the next method in the list. My reasoning for this is that you would |
470 | almost never want to do this, since it usually breaks your class. As with |
471 | overriding locally defined methods, if you do want to do this, you should do it |
472 | manually, not with Moose. |
38e3283b |
473 | |
f3c4e20e |
474 | You do not I<need> to have a reader (or accessor) for the attribute in order |
475 | to delegate to it. Moose will create a means of accessing the value for you, |
476 | however this will be several times B<less> efficient then if you had given |
477 | the attribute a reader (or accessor) to use. |
478 | |
38e3283b |
479 | Below is the documentation for each option format: |
480 | |
481 | =over 4 |
482 | |
483 | =item C<ARRAY> |
484 | |
26fbace8 |
485 | This is the most common usage for I<handles>. You basically pass a list of |
486 | method names to be delegated, and Moose will install a delegation method |
1cd45431 |
487 | for each one. |
38e3283b |
488 | |
489 | =item C<HASH> |
490 | |
26fbace8 |
491 | This is the second most common usage for I<handles>. Instead of a list of |
492 | method names, you pass a HASH ref where each key is the method name you |
493 | want installed locally, and its value is the name of the original method |
494 | in the class being delegated to. |
fd595040 |
495 | |
26fbace8 |
496 | This can be very useful for recursive classes like trees. Here is a |
5cfe3805 |
497 | quick example (soon to be expanded into a Moose::Cookbook recipe): |
38e3283b |
498 | |
1cd45431 |
499 | package Tree; |
38e3283b |
500 | use Moose; |
26fbace8 |
501 | |
38e3283b |
502 | has 'node' => (is => 'rw', isa => 'Any'); |
26fbace8 |
503 | |
38e3283b |
504 | has 'children' => ( |
505 | is => 'ro', |
506 | isa => 'ArrayRef', |
507 | default => sub { [] } |
508 | ); |
26fbace8 |
509 | |
38e3283b |
510 | has 'parent' => ( |
511 | is => 'rw', |
512 | isa => 'Tree', |
a4e516f6 |
513 | weak_ref => 1, |
38e3283b |
514 | handles => { |
515 | parent_node => 'node', |
26fbace8 |
516 | siblings => 'children', |
38e3283b |
517 | } |
518 | ); |
519 | |
1cd45431 |
520 | In this example, the Tree package gets C<parent_node> and C<siblings> methods, |
521 | which delegate to the C<node> and C<children> methods (respectively) of the Tree |
26fbace8 |
522 | instance stored in the C<parent> slot. |
38e3283b |
523 | |
524 | =item C<REGEXP> |
525 | |
26fbace8 |
526 | The regexp option works very similar to the ARRAY option, except that it builds |
527 | the list of methods for you. It starts by collecting all possible methods of the |
528 | class being delegated to, then filters that list using the regexp supplied here. |
38e3283b |
529 | |
26fbace8 |
530 | B<NOTE:> An I<isa> option is required when using the regexp option format. This |
531 | is so that we can determine (at compile time) the method list from the class. |
38e3283b |
532 | Without an I<isa> this is just not possible. |
533 | |
c84f324f |
534 | =item C<ROLE> |
535 | |
26fbace8 |
536 | With the role option, you specify the name of a role whose "interface" then |
537 | becomes the list of methods to handle. The "interface" can be defined as; the |
538 | methods of the role and any required methods of the role. It should be noted |
539 | that this does B<not> include any method modifiers or generated attribute |
c84f324f |
540 | methods (which is consistent with role composition). |
541 | |
38e3283b |
542 | =item C<CODE> |
543 | |
1cd45431 |
544 | This is the option to use when you really want to do something funky. You should |
545 | only use it if you really know what you are doing, as it involves manual |
546 | metaclass twiddling. |
38e3283b |
547 | |
1cd45431 |
548 | This takes a code reference, which should expect two arguments. The first is the |
549 | attribute meta-object this I<handles> is attached to. The second is the |
550 | metaclass of the class being delegated to. It expects you to return a hash (not |
26fbace8 |
551 | a HASH ref) of the methods you want mapped. |
38e3283b |
552 | |
553 | =back |
2c0cbef7 |
554 | |
004222dc |
555 | =item I<metaclass =E<gt> $metaclass_name> |
556 | |
557 | This tells the class to use a custom attribute metaclass for this particular |
558 | attribute. Custom attribute metaclasses are useful for extending the |
559 | capabilities of the I<has> keyword: they are the simplest way to extend the MOP, |
560 | but they are still a fairly advanced topic and too much to cover here, see |
5cfe3805 |
561 | L<Moose::Cookbook::Meta::Recipe1> for more information. |
004222dc |
562 | |
563 | The default behavior here is to just load C<$metaclass_name>; however, we also |
564 | have a way to alias to a shorter name. This will first look to see if |
565 | B<Moose::Meta::Attribute::Custom::$metaclass_name> exists. If it does, Moose |
566 | will then check to see if that has the method C<register_implementation>, which |
567 | should return the actual name of the custom attribute metaclass. If there is no |
568 | C<register_implementation> method, it will fall back to using |
569 | B<Moose::Meta::Attribute::Custom::$metaclass_name> as the metaclass name. |
570 | |
571 | =item I<traits =E<gt> [ @role_names ]> |
572 | |
573 | This tells Moose to take the list of C<@role_names> and apply them to the |
574 | attribute meta-object. This is very similar to the I<metaclass> option, but |
54f2996d |
575 | allows you to use more than one extension at a time. |
004222dc |
576 | |
54f2996d |
577 | See L<TRAIT NAME RESOLUTION> for details on how a trait name is |
578 | resolved to a class name. |
579 | |
580 | Also see L<Moose::Cookbook::Meta::Recipe3> for a metaclass trait |
581 | example. |

019f031d |
583 | =item I<builder> => Str |
010997ca |
584 | |
1b46b845 |
585 | The value of this key is the name of the method that will be called to |
586 | obtain the value used to initialize the attribute. See the L<builder |
587 | option docs in Class::MOP::Attribute|Class::MOP::Attribute/builder> |
588 | for more information. |
010997ca |
589 | |
019f031d |
590 | =item I<default> => SCALAR | CODE |
010997ca |
591 | |
592 | The value of this key is the default value which will initialize the attribute. |
593 | |
1b46b845 |
594 | NOTE: If the value is a simple scalar (string or number), then it can |
595 | be just passed as is. However, if you wish to initialize it with a |
596 | HASH or ARRAY ref, then you need to wrap that inside a CODE reference. |
597 | See the L<default option docs in |
598 | Class::MOP::Attribute|Class::MOP::Attribute/default> for more |
599 | information. |
010997ca |
600 | |
019f031d |
601 | =item I<initializer> => Str |
010997ca |
602 | |
1b46b845 |
603 | This may be a method name (referring to a method on the class with |
604 | this attribute) or a CODE ref. The initializer is used to set the |
605 | attribute value on an instance when the attribute is set during |
606 | instance initialization (but not when the value is being assigned |
607 | to). See the L<initializer option docs in |
608 | Class::MOP::Attribute|Class::MOP::Attribute/initializer> for more |
609 | information. |
010997ca |
610 | |
019f031d |
611 | =item I<clearer> => Str |
010997ca |
612 | |
1b46b845 |
613 | Allows you to clear the value, see the L<clearer option docs in |
614 | Class::MOP::Attribute|Class::MOP::Attribute/clearer> for more |
615 | information. |
010997ca |
616 | |
019f031d |
617 | =item I<predicate> => Str |
010997ca |
618 | |
1b46b845 |
619 | Basic test to see if a value has been set in the attribute, see the |
620 | L<predicate option docs in |
621 | Class::MOP::Attribute|Class::MOP::Attribute/predicate> for more |
622 | information. |
010997ca |
623 | |
019f031d |
624 | =item I<lazy_build> => (0|1) |
625 | |
626 | Automatically define lazy => 1 as well as builder => "_build_$attr", clearer => |
627 | "clear_$attr', predicate => 'has_$attr' unless they are already defined. |

cd7eeaf5 |
632 | =item B<has +$name =E<gt> %options> |
633 | |
c7874946 |
634 | This is variation on the normal attribute creator C<has> which allows you to |
8d62bf6d |
635 | clone and extend an attribute from a superclass or from a role. Here is an |
636 | example of the superclass usage: |
cd7eeaf5 |
637 | |
638 | package Foo; |
639 | use Moose; |
26fbace8 |
640 | |
cd7eeaf5 |
641 | has 'message' => ( |
26fbace8 |
642 | is => 'rw', |
cd7eeaf5 |
643 | isa => 'Str', |
644 | default => 'Hello, I am a Foo' |
645 | ); |
26fbace8 |
646 | |
cd7eeaf5 |
647 | package My::Foo; |
648 | use Moose; |
26fbace8 |
649 | |
cd7eeaf5 |
650 | extends 'Foo'; |
26fbace8 |
651 | |
cd7eeaf5 |
652 | has '+message' => (default => 'Hello I am My::Foo'); |
653 | |
1cd45431 |
654 | What is happening here is that B<My::Foo> is cloning the C<message> attribute |
655 | from its parent class B<Foo>, retaining the C<is =E<gt> 'rw'> and C<isa =E<gt> |
656 | 'Str'> characteristics, but changing the value in C<default>. |
cd7eeaf5 |
657 | |
8d62bf6d |
658 | Here is another example, but within the context of a role: |
659 | |
660 | package Foo::Role; |
661 | use Moose::Role; |
986d175a |
662 | |
8d62bf6d |
663 | has 'message' => ( |
664 | is => 'rw', |
665 | isa => 'Str', |
666 | default => 'Hello, I am a Foo' |
667 | ); |
986d175a |
668 | |
8d62bf6d |
669 | package My::Foo; |
670 | use Moose; |
986d175a |
671 | |
8d62bf6d |
672 | with 'Foo::Role'; |
986d175a |
673 | |
8d62bf6d |
674 | has '+message' => (default => 'Hello I am My::Foo'); |
675 | |
676 | In this case, we are basically taking the attribute which the role supplied |
4032c9bb |
677 | and altering it within the bounds of this feature. |
8d62bf6d |
678 | |
4032c9bb |
679 | Aside from where the attributes come from (one from superclass, the other |
680 | from a role), this feature works exactly the same. This feature is restricted |
681 | somewhat, so as to try and force at least I<some> sanity into it. You are only |
682 | allowed to change the following attributes: |
cd7eeaf5 |
683 | |
684 | =over 4 |
685 | |
26fbace8 |
686 | =item I<default> |
cd7eeaf5 |
687 | |
688 | Change the default value of an attribute. |
689 | |
26fbace8 |
690 | =item I<coerce> |
cd7eeaf5 |
691 | |
692 | Change whether the attribute attempts to coerce a value passed to it. |
693 | |
26fbace8 |
694 | =item I<required> |
cd7eeaf5 |
695 | |
696 | Change if the attribute is required to have a value. |
697 | |
698 | =item I<documentation> |
699 | |
700 | Change the documentation string associated with the attribute. |
701 | |
83cc9094 |
702 | =item I<lazy> |
703 | |
704 | Change if the attribute lazily initializes the slot. |
705 | |
cd7eeaf5 |
706 | =item I<isa> |
707 | |
aed87761 |
708 | You I<are> allowed to change the type without restriction. |
709 | |
710 | It is recommended that you use this freedom with caution. We used to |
711 | only allow for extension only if the type was a subtype of the parent's |
712 | type, but we felt that was too restrictive and is better left as a |
c7874946 |
713 | policy decision. |
cd7eeaf5 |
714 | |
83cc9094 |
715 | =item I<handles> |
716 | |
26fbace8 |
717 | You are allowed to B<add> a new C<handles> definition, but you are B<not> |

83cc9094 |
719 | |
8d62bf6d |
720 | =item I<builder> |

728 | B<not> allowed to I<change> one. |
729 | |
730 | =item I<traits> |
731 | |
732 | You are allowed to B<add> additional traits to the C<traits> definition. |
733 | These traits will be composed into the attribute, but pre-existing traits |
734 | B<are not> overridden, or removed. |

744 | This three items are syntactic sugar for the before, after, and around method |
745 | modifier features that L<Class::MOP> provides. More information on these may be |
746 | found in the L<Class::MOP::Class documentation|Class::MOP::Class/"Method |

6ba6d68c |
748 | |
159da176 |
749 | =item B<super> |
750 | |
26fbace8 |
751 | The keyword C<super> is a no-op when called outside of an C<override> method. In |
752 | the context of an C<override> method, it will call the next most appropriate |
159da176 |
753 | superclass method with the same arguments as the original method. |
754 | |
755 | =item B<override ($name, &sub)> |
756 | |
26fbace8 |
757 | An C<override> method is a way of explicitly saying "I am overriding this |
758 | method from my superclass". You can call C<super> within this method, and |
759 | it will work as expected. The same thing I<can> be accomplished with a normal |
760 | method call and the C<SUPER::> pseudo-package; it is really your choice. |
159da176 |
761 | |
762 | =item B<inner> |
763 | |
26fbace8 |
764 | The keyword C<inner>, much like C<super>, is a no-op outside of the context of |
765 | an C<augment> method. You can think of C<inner> as being the inverse of |
68efb014 |
766 | C<super>; the details of how C<inner> and C<augment> work is best described in |
5cfe3805 |
767 | the L<Moose::Cookbook::Basics::Recipe6>. |
159da176 |
768 | |
769 | =item B<augment ($name, &sub)> |
770 | |
26fbace8 |
771 | An C<augment> method, is a way of explicitly saying "I am augmenting this |
772 | method from my superclass". Once again, the details of how C<inner> and |
5cfe3805 |
773 | C<augment> work is best described in the L<Moose::Cookbook::Basics::Recipe6>. |
159da176 |
774 | |
6ba6d68c |
775 | =item B<confess> |

777 | This is the C<Carp::confess> function, and exported here because I use it |
004222dc |
778 | all the time. |
6ba6d68c |
779 | |
780 | =item B<blessed> |
781 | |
1cd45431 |
782 | This is the C<Scalar::Util::blessed> function, it is exported here because I |
26fbace8 |
783 | use it all the time. It is highly recommended that this is used instead of |
6ba6d68c |
784 | C<ref> anywhere you need to test for an object's class name. |

788 | =head1 METACLASS TRAITS |
789 | |
790 | When you use Moose, you can also specify traits which will be applied |
791 | to your metaclass: |
792 | |
793 | use Moose -traits => 'My::Trait'; |
794 | |
795 | This is very similar to the attribute traits feature. When you do |
796 | this, your class's C<meta> object will have the specified traits |
797 | applied to it. See L<TRAIT NAME RESOLUTION> for more details. |
798 | |
799 | =head1 TRAIT NAME RESOLUTION |
800 | |
801 | By default, when given a trait name, Moose simply tries to load a |
802 | class of the same name. If such a class does not exist, it then looks |
803 | for for a class matching |
804 | B<Moose::Meta::$type::Custom::Trait::$trait_name>. The C<$type> |
805 | variable here will be one of B<Attribute> or B<Class>, depending on |
806 | what the trait is being applied to. |
807 | |
808 | If a class with this long name exists, Moose checks to see if it has |
809 | the method C<register_implementation>. This method is expected to |
810 | return the I<real> class name of the trait. If there is no |
811 | C<register_implementation> method, it will fall back to using |
812 | B<Moose::Meta::$type::Custom::Trait::$trait> as the trait name. |
813 | |
814 | If all this is confusing, take a look at |
815 | L<Moose::Cookbook::Meta::Recipe3>, which demonstrates how to create an |
816 | attribute trait. |

820 | =head2 B<unimport> |
821 | |
1cd45431 |
822 | Moose offers a way to remove the keywords it exports, through the C<unimport> |
31f8ec72 |
823 | method. You simply have to say C<no Moose> at the bottom of your code for this |
824 | to work. Here is an example: |
825 | |
826 | package Person; |
827 | use Moose; |
828 | |
829 | has 'first_name' => (is => 'rw', isa => 'Str'); |
830 | has 'last_name' => (is => 'rw', isa => 'Str'); |
26fbace8 |
831 | |
832 | sub full_name { |
31f8ec72 |
833 | my $self = shift; |
26fbace8 |
834 | $self->first_name . ' ' . $self->last_name |
31f8ec72 |
835 | } |
26fbace8 |
836 | |
837 | no Moose; # keywords are removed from the Person package |

839 | =head1 EXTENDING AND EMBEDDING MOOSE |
840 | |
5e86efbe |
841 | To learn more about extending Moose, we recommend checking out the |
842 | "Extending" recipes in the L<Moose::Cookbook>, starting with |
843 | L<Moose::Cookbook::Extending::Recipe1>, which provides an overview of |
844 | all the different ways you might extend Moose. |

9bcfbab1 |
847 | |
554b7648 |
848 | The C<init_meta> method sets up the metaclass object for the class |
b143539e |
849 | specified by C<for_class>. This method injects a a C<meta> accessor |
850 | into the class so you can get at this object. It also sets the class's |
554b7648 |
851 | superclass to C<base_class>, with L<Moose::Object> as the default. |
9bcfbab1 |
852 | |
554b7648 |
853 | You can specify an alternate metaclass with the C<metaclass> parameter. |

855 | For more detail on this topic, see L<Moose::Cookbook::Extending::Recipe2>. |
856 | |
554b7648 |
857 | This method used to be documented as a function which accepted |
858 | positional parameters. This calling style will still work for |
4a66a4b3 |
859 | backwards compatibility, but is deprecated. |
554b7648 |
860 | |
861 | =head2 B<import> |
862 | |
863 | Moose's C<import> method supports the L<Sub::Exporter> form of C<{into =E<gt> $pkg}> |
864 | and C<{into_level =E<gt> 1}>. |
865 | |
866 | B<NOTE>: Doing this is more or less deprecated. Use L<Moose::Exporter> |
867 | instead, which lets you stack multiple C<Moose.pm>-alike modules |
868 | sanely. It handles getting the exported functions into the right place |
869 | for you. |

875 | =head1 METACLASS COMPATIBILITY AND MOOSE |
876 | |
877 | Metaclass compatibility is a thorny subject. You should start by |
878 | reading the "About Metaclass compatibility" section in the |
879 | C<Class::MOP> docs. |
880 | |
881 | Moose will attempt to resolve a few cases of metaclass incompatibility |
882 | when you set the superclasses for a class, unlike C<Class::MOP>, which |
883 | simply dies if the metaclasses are incompatible. |
884 | |
885 | In actuality, Moose fixes incompatibility for I<all> of a class's |
886 | metaclasses, not just the class metaclass. That includes the instance |
887 | metaclass, attribute metaclass, as well as its constructor class and |
888 | destructor class. However, for simplicity this discussion will just |
889 | refer to "metaclass", meaning the class metaclass, most of the time. |
890 | |
891 | Moose has two algorithms for fixing metaclass incompatibility. |
892 | |
893 | The first algorithm is very simple. If all the metaclass for the |
894 | parent is a I<subclass> of the child's metaclass, then we simply |
895 | replace the child's metaclass with the parent's. |
896 | |
897 | The second algorithm is more complicated. It tries to determine if the |
898 | metaclasses only "differ by roles". This means that the parent and |
899 | child's metaclass share a common ancestor in their respective |
900 | hierarchies, and that the subclasses under the common ancestor are |
901 | only different because of role applications. This case is actually |
902 | fairly common when you mix and match various C<MooseX::*> modules, |
903 | many of which apply roles to the metaclass. |
904 | |
905 | If the parent and child do differ by roles, Moose replaces the |
906 | metaclass in the child with a newly created metaclass. This metaclass |
907 | is a subclass of the parent's metaclass, does all of the roles that |
908 | the child's metaclass did before being replaced. Effectively, this |
909 | means the new metaclass does all of the roles done by both the |
910 | parent's and child's original metaclasses. |
911 | |
912 | Ultimately, this is all transparent to you except in the case of an |
913 | unresolvable conflict. |

915 | =head2 The MooseX:: namespace |
916 | |
917 | Generally if you're writing an extension I<for> Moose itself you'll want |
918 | to put your extension in the C<MooseX::> namespace. This namespace is |
919 | specifically for extensions that make Moose better or different in some |
920 | fundamental way. It is traditionally B<not> for a package that just happens |
921 | to use Moose. This namespace follows from the examples of the C<LWPx::> |
922 | and C<DBIx::> namespaces that perform the same function for C<LWP> and C<DBI> |
923 | respectively. |

930 | |
1cd45431 |
931 | It should be noted that C<super> and C<inner> B<cannot> be used in the same |
932 | method. However, they may be combined within the same class hierarchy; see |
933 | F<t/014_override_augment_inner_super.t> for an example. |
05d9eaf6 |
934 | |
26fbace8 |
935 | The reason for this is that C<super> is only valid within a method |
936 | with the C<override> modifier, and C<inner> will never be valid within an |
937 | C<override> method. In fact, C<augment> will skip over any C<override> methods |
68efb014 |
938 | when searching for its appropriate C<inner>. |
05d9eaf6 |
939 | |
1cd45431 |
940 | This might seem like a restriction, but I am of the opinion that keeping these |
941 | two features separate (yet interoperable) actually makes them easy to use, since |
942 | their behavior is then easier to predict. Time will tell whether I am right or |
c84f324f |
943 | not (UPDATE: so far so good). |

1031 | We are very strict about what features we add to the Moose core, especially |
1032 | the user-visible features. Instead we have made sure that the underlying |
1033 | meta-system of Moose is as extensible as possible so that you can add your |
1034 | own features easily. That said, occasionally there is a feature needed in the |
1035 | meta-system to support your planned extension, in which case you should |
1036 | either email the mailing list or join us on irc at #moose to discuss. |
