300 | Moose is a rapidly maturing module, and is already being used by |
301 | a number of people. It's test suite is growing larger by the day, |
302 | and the docs should soon follow. |
303 | |
304 | This said, Moose is not yet finished, and should still be considered |
305 | to be evolving. Much of the outer API is stable, but the internals |
306 | are still subject to change (although not without serious thought |
307 | given to it). |
308 | |
309 | For more details, please refer to the L<FUTURE PLANS> section of |
310 | this document. |

312 | =head1 DESCRIPTION |
313 | |
e522431d |
314 | Moose is an extension of the Perl 5 object system. |
315 | |
316 | =head2 Another object system!?!? |
fcd84ca9 |
317 | |
e522431d |
318 | Yes, I know there has been an explosion recently of new ways to |
319 | build object's in Perl 5, most of them based on inside-out objects, |
320 | and other such things. Moose is different because it is not a new |
321 | object system for Perl 5, but instead an extension of the existing |
322 | object system. |
3c7278fb |
323 | |
e522431d |
324 | Moose is built on top of L<Class::MOP>, which is a metaclass system |
325 | for Perl 5. This means that Moose not only makes building normal |
505c6fac |
326 | Perl 5 objects better, but it also provides the power of metaclass |
327 | programming. |
e522431d |
328 | |
2c0cbef7 |
329 | =head2 Can I use this in production? Or is this just an experiment? |
e522431d |
330 | |
2c0cbef7 |
331 | Moose is I<based> on the prototypes and experiments I did for the Perl 6 |
332 | meta-model, however Moose is B<NOT> an experiment/prototype, it is |
43d599e5 |
333 | for B<real>. I will be deploying Moose into production environments later |
334 | this year, and I have all intentions of using it as my de-facto class |
335 | builderfrom now on. |
e522431d |
336 | |
43d599e5 |
337 | =head2 Is Moose just Perl 6 in Perl 5? |
e522431d |
338 | |
2c0cbef7 |
339 | No. While Moose is very much inspired by Perl 6, it is not. Instead, it |
43d599e5 |
340 | is an OO system for Perl 5. I built Moose because I was tired or writing |
341 | the same old boring Perl 5 OO code, and drooling over Perl 6 OO. So |
342 | instead of switching to Ruby, I wrote Moose :) |
3c7278fb |
343 | |
6ba6d68c |
344 | =head1 BUILDING CLASSES WITH MOOSE |
345 | |
346 | Moose makes every attempt to provide as much convience during class |
347 | construction/definition, but still stay out of your way if you want |
43d599e5 |
348 | it to. Here are a few items to note when building classes with Moose. |
6ba6d68c |
349 | |
350 | Unless specified with C<extends>, any class which uses Moose will |
351 | inherit from L<Moose::Object>. |
352 | |
353 | Moose will also manage all attributes (including inherited ones) that |
354 | are defined with C<has>. And assuming that you call C<new> which is |
355 | inherited from L<Moose::Object>, then this includes properly initializing |
356 | all instance slots, setting defaults where approprtiate and performing any |
357 | type constraint checking or coercion. |
358 | |
359 | =head1 EXPORTED FUNCTIONS |
360 | |
361 | Moose will export a number of functions into the class's namespace, which |
362 | can then be used to set up the class. These functions all work directly |
363 | on the current class. |
364 | |
365 | =over 4 |
366 | |
367 | =item B<meta> |
368 | |
369 | This is a method which provides access to the current class's metaclass. |
370 | |
371 | =item B<extends (@superclasses)> |
372 | |
373 | This function will set the superclass(es) for the current class. |
374 | |
375 | This approach is recommended instead of C<use base>, because C<use base> |
376 | actually C<push>es onto the class's C<@ISA>, whereas C<extends> will |
377 | replace it. This is important to ensure that classes which do not have |
378 | superclasses properly inherit from L<Moose::Object>. |
379 | |
43d599e5 |
380 | =item B<with (@roles)> |
e9ec68d6 |
381 | |
43d599e5 |
382 | This will apply a given set of C<@roles> to the local class. Role support |
2c0cbef7 |
383 | is currently under heavy development, see L<Moose::Role> for more details. |
e9ec68d6 |
384 | |
6ba6d68c |
385 | =item B<has ($name, %options)> |
386 | |
387 | This will install an attribute of a given C<$name> into the current class. |
43d599e5 |
388 | The list of C<%options> are the same as those provided by |
389 | L<Class::MOP::Attribute>, in addition to the list below which are provided |
390 | by Moose (L<Moose::Meta::Attribute> to be more specific): |
6ba6d68c |
391 | |
392 | =over 4 |
393 | |
076c81ed |
394 | =item I<is =E<gt> 'rw'|'ro'> |
6ba6d68c |
395 | |
396 | The I<is> option accepts either I<rw> (for read/write) or I<ro> (for read |
397 | only). These will create either a read/write accessor or a read-only |
398 | accessor respectively, using the same name as the C<$name> of the attribute. |
399 | |
400 | If you need more control over how your accessors are named, you can use the |
43d599e5 |
401 | I<reader>, I<writer> and I<accessor> options inherited from L<Class::MOP::Attribute>. |
6ba6d68c |
402 | |
076c81ed |
403 | =item I<isa =E<gt> $type_name> |
6ba6d68c |
404 | |
405 | The I<isa> option uses Moose's type constraint facilities to set up runtime |
406 | type checking for this attribute. Moose will perform the checks during class |
407 | construction, and within any accessors. The C<$type_name> argument must be a |
408 | string. The string can be either a class name, or a type defined using |
409 | Moose's type defintion features. |
410 | |
daea75c9 |
411 | =item I<coerce =E<gt> (1|0)> |
412 | |
413 | This will attempt to use coercion with the supplied type constraint to change |
414 | the value passed into any accessors of constructors. You B<must> have supplied |
415 | a type constraint in order for this to work. See L<Moose::Cookbook::Recipe5> |
416 | for an example usage. |
417 | |
418 | =item I<does =E<gt> $role_name> |
419 | |
420 | This will accept the name of a role which the value stored in this attribute |
421 | is expected to have consumed. |
422 | |
423 | =item I<required =E<gt> (1|0)> |
424 | |
425 | This marks the attribute as being required. This means a value must be supplied |
426 | during class construction, and the attribute can never be set to C<undef> with |
427 | an accessor. |
428 | |
429 | =item I<weak_ref =E<gt> (1|0)> |
430 | |
431 | This will tell the class to strore the value of this attribute as a weakened |
432 | reference. If an attribute is a weakened reference, it can B<not> also be coerced. |
433 | |
434 | =item I<lazy =E<gt> (1|0)> |

436 | This will tell the class to not create this slot until absolutely nessecary. |
437 | If an attribute is marked as lazy it B<must> have a default supplied. |
438 | |

439 | =item I<auto_deref =E<gt> (1|0)> |
440 | |
441 | This tells the accessor whether to automatically de-reference the value returned. |
442 | This is only legal if your C<isa> option is either an C<ArrayRef> or C<HashRef>. |
443 | |

444 | =item I<trigger =E<gt> $code> |
445 | |
446 | The trigger option is a CODE reference which will be called after the value of |
447 | the attribute is set. The CODE ref will be passed the instance itself, the |
448 | updated value and the attribute meta-object (this is for more advanced fiddling |
cce8198b |
449 | and can typically be ignored in most cases). You can B<not> have a trigger on |
450 | a read-only attribute. |

452 | =item I<handles =E<gt> [ @handles ]> |
453 | |
454 | There is experimental support for attribute delegation using the C<handles> |
455 | option. More docs to come later. |

465 | This three items are syntactic sugar for the before, after and around method |
466 | modifier features that L<Class::MOP> provides. More information on these can |
467 | be found in the L<Class::MOP> documentation for now. |

469 | =item B<super> |
470 | |
471 | The keyword C<super> is a noop when called outside of an C<override> method. In |
472 | the context of an C<override> method, it will call the next most appropriate |
473 | superclass method with the same arguments as the original method. |
474 | |
475 | =item B<override ($name, &sub)> |
476 | |
477 | An C<override> method, is a way of explictly saying "I am overriding this |
478 | method from my superclass". You can call C<super> within this method, and |
479 | it will work as expected. The same thing I<can> be accomplished with a normal |
480 | method call and the C<SUPER::> pseudo-package, it is really your choice. |
481 | |
482 | =item B<inner> |
483 | |
484 | The keyword C<inner>, much like C<super>, is a no-op outside of the context of |
485 | an C<augment> method. You can think of C<inner> as being the inverse of |
486 | C<super>, the details of how C<inner> and C<augment> work is best described in |
487 | the L<Moose::Cookbook>. |
488 | |
489 | =item B<augment ($name, &sub)> |
490 | |
491 | An C<augment> method, is a way of explictly saying "I am augmenting this |
492 | method from my superclass". Once again, the details of how C<inner> and |
493 | C<augment> work is best described in the L<Moose::Cookbook>. |
494 | |

495 | =item B<confess> |
496 | |
497 | This is the C<Carp::confess> function, and exported here beause I use it |
498 | all the time. This feature may change in the future, so you have been warned. |
499 | |
500 | =item B<blessed> |
501 | |
502 | This is the C<Scalar::Uti::blessed> function, it is exported here beause I |
503 | use it all the time. It is highly recommended that this is used instead of |
504 | C<ref> anywhere you need to test for an object's class name. |

508 | =head1 FUTURE PLANS |
509 | |
510 | Here is just a sampling of the plans we have in store for Moose: |
511 | |
512 | =over 4 |
513 | |
514 | =item * |
515 | |
516 | Compiling Moose classes/roles into C<.pmc> files for faster loading and execution. |
517 | |
518 | =item * |
519 | |
520 | Supporting sealed and finalized classes in Moose. This will allow greater control |
521 | of the extensions of frameworks and such. |
522 | |
523 | =back |
524 | |
525 | =head1 MISC. |
526 | |
527 | =head2 What does Moose stand for?? |
528 | |
529 | Moose doesn't stand for one thing in particular, however, if you |
530 | want, here are a few of my favorites, feel free to contribute |
531 | more :) |
532 | |
533 | =over 4 |
534 | |
535 | =item Make Other Object Systems Envious |
536 | |
537 | =item Makes Object Orientation So Easy |
538 | |
539 | =item Makes Object Orientation Spiffy- Er (sorry ingy) |
540 | |
541 | =item Most Other Object Systems Emasculate |
542 | |
2c0cbef7 |
543 | =item Moose Often Ovulate Sorta Early |
544 | |
2c0cbef7 |
545 | =item Moose Offers Often Super Extensions |
546 | |
547 | =item Meta Object Orientation Syntax Extensions |
548 | |
549 | =back |
550 | |

551 | =head1 CAVEATS |
552 | |
553 | =over 4 |
554 | |
555 | =item * |
556 | |
557 | It should be noted that C<super> and C<inner> can B<not> be used in the same |
558 | method. However, they can be combined together with the same class hierarchy, |
559 | see F<t/014_override_augment_inner_super.t> for an example. |
560 | |
561 | The reason that this is so is because C<super> is only valid within a method |
562 | with the C<override> modifier, and C<inner> will never be valid within an |
563 | C<override> method. In fact, C<augment> will skip over any C<override> methods |
564 | when searching for it's appropriate C<inner>. |
565 | |
566 | This might seem like a restriction, but I am of the opinion that keeping these |
567 | two features seperate (but interoperable) actually makes them easy to use since |
568 | their behavior is then easier to predict. Time will tell if I am right or not. |
