297 | |
2c0cbef7 |
298 | Moose is a rapidly maturing module, and is already being used by |
299 | a number of people. It's test suite is growing larger by the day, |
300 | and the docs should soon follow. |
301 | |
302 | This said, Moose is not yet finished, and should still be considered |
303 | to be evolving. Much of the outer API is stable, but the internals |
304 | are still subject to change (although not without serious thought |
305 | given to it). |
306 | |
307 | For more details, please refer to the L<FUTURE PLANS> section of |
308 | this document. |

310 | =head1 DESCRIPTION |
311 | |
e522431d |
312 | Moose is an extension of the Perl 5 object system. |
313 | |
314 | =head2 Another object system!?!? |
fcd84ca9 |
315 | |
e522431d |
316 | Yes, I know there has been an explosion recently of new ways to |
317 | build object's in Perl 5, most of them based on inside-out objects, |
318 | and other such things. Moose is different because it is not a new |
319 | object system for Perl 5, but instead an extension of the existing |
320 | object system. |
3c7278fb |
321 | |
e522431d |
322 | Moose is built on top of L<Class::MOP>, which is a metaclass system |
323 | for Perl 5. This means that Moose not only makes building normal |
505c6fac |
324 | Perl 5 objects better, but it also provides the power of metaclass |
325 | programming. |
e522431d |
326 | |
2c0cbef7 |
327 | =head2 Can I use this in production? Or is this just an experiment? |
e522431d |
328 | |
2c0cbef7 |
329 | Moose is I<based> on the prototypes and experiments I did for the Perl 6 |
330 | meta-model, however Moose is B<NOT> an experiment/prototype, it is |
43d599e5 |
331 | for B<real>. I will be deploying Moose into production environments later |
332 | this year, and I have all intentions of using it as my de-facto class |
333 | builderfrom now on. |
e522431d |
334 | |
43d599e5 |
335 | =head2 Is Moose just Perl 6 in Perl 5? |
e522431d |
336 | |
2c0cbef7 |
337 | No. While Moose is very much inspired by Perl 6, it is not. Instead, it |
43d599e5 |
338 | is an OO system for Perl 5. I built Moose because I was tired or writing |
339 | the same old boring Perl 5 OO code, and drooling over Perl 6 OO. So |
340 | instead of switching to Ruby, I wrote Moose :) |
3c7278fb |
341 | |
6ba6d68c |
342 | =head1 BUILDING CLASSES WITH MOOSE |
343 | |
344 | Moose makes every attempt to provide as much convience during class |
345 | construction/definition, but still stay out of your way if you want |
43d599e5 |
346 | it to. Here are a few items to note when building classes with Moose. |
6ba6d68c |
347 | |
348 | Unless specified with C<extends>, any class which uses Moose will |
349 | inherit from L<Moose::Object>. |
350 | |
351 | Moose will also manage all attributes (including inherited ones) that |
352 | are defined with C<has>. And assuming that you call C<new> which is |
353 | inherited from L<Moose::Object>, then this includes properly initializing |
354 | all instance slots, setting defaults where approprtiate and performing any |
355 | type constraint checking or coercion. |
356 | |
357 | =head1 EXPORTED FUNCTIONS |
358 | |
359 | Moose will export a number of functions into the class's namespace, which |
360 | can then be used to set up the class. These functions all work directly |
361 | on the current class. |
362 | |
363 | =over 4 |
364 | |
365 | =item B<meta> |
366 | |
367 | This is a method which provides access to the current class's metaclass. |
368 | |
369 | =item B<extends (@superclasses)> |
370 | |
371 | This function will set the superclass(es) for the current class. |
372 | |
373 | This approach is recommended instead of C<use base>, because C<use base> |
374 | actually C<push>es onto the class's C<@ISA>, whereas C<extends> will |
375 | replace it. This is important to ensure that classes which do not have |
376 | superclasses properly inherit from L<Moose::Object>. |
377 | |
43d599e5 |
378 | =item B<with (@roles)> |
e9ec68d6 |
379 | |
43d599e5 |
380 | This will apply a given set of C<@roles> to the local class. Role support |
2c0cbef7 |
381 | is currently under heavy development, see L<Moose::Role> for more details. |
e9ec68d6 |
382 | |
6ba6d68c |
383 | =item B<has ($name, %options)> |
384 | |
385 | This will install an attribute of a given C<$name> into the current class. |
43d599e5 |
386 | The list of C<%options> are the same as those provided by |
387 | L<Class::MOP::Attribute>, in addition to the list below which are provided |
388 | by Moose (L<Moose::Meta::Attribute> to be more specific): |
6ba6d68c |
389 | |
390 | =over 4 |
391 | |
076c81ed |
392 | =item I<is =E<gt> 'rw'|'ro'> |
6ba6d68c |
393 | |
394 | The I<is> option accepts either I<rw> (for read/write) or I<ro> (for read |
395 | only). These will create either a read/write accessor or a read-only |
396 | accessor respectively, using the same name as the C<$name> of the attribute. |
397 | |
398 | If you need more control over how your accessors are named, you can use the |
43d599e5 |
399 | I<reader>, I<writer> and I<accessor> options inherited from L<Class::MOP::Attribute>. |
6ba6d68c |
400 | |
076c81ed |
401 | =item I<isa =E<gt> $type_name> |
6ba6d68c |
402 | |
403 | The I<isa> option uses Moose's type constraint facilities to set up runtime |
404 | type checking for this attribute. Moose will perform the checks during class |
405 | construction, and within any accessors. The C<$type_name> argument must be a |
406 | string. The string can be either a class name, or a type defined using |
407 | Moose's type defintion features. |
408 | |
daea75c9 |
409 | =item I<coerce =E<gt> (1|0)> |
410 | |
411 | This will attempt to use coercion with the supplied type constraint to change |
412 | the value passed into any accessors of constructors. You B<must> have supplied |
413 | a type constraint in order for this to work. See L<Moose::Cookbook::Recipe5> |
414 | for an example usage. |
415 | |
416 | =item I<does =E<gt> $role_name> |
417 | |
418 | This will accept the name of a role which the value stored in this attribute |
419 | is expected to have consumed. |
420 | |
421 | =item I<required =E<gt> (1|0)> |
422 | |
423 | This marks the attribute as being required. This means a value must be supplied |
424 | during class construction, and the attribute can never be set to C<undef> with |
425 | an accessor. |
426 | |
427 | =item I<weak_ref =E<gt> (1|0)> |
428 | |
429 | This will tell the class to strore the value of this attribute as a weakened |
430 | reference. If an attribute is a weakened reference, it can B<not> also be coerced. |
431 | |
432 | =item I<lazy =E<gt> (1|0)> |
433 | |
434 | This will tell the class to not create this slot until absolutely nessecary. |
435 | If an attribute is marked as lazy it B<must> have a default supplied. |
436 | |

437 | =item I<auto_deref =E<gt> (1|0)> |
438 | |
439 | This tells the accessor whether to automatically de-reference the value returned. |
440 | This is only legal if your C<isa> option is either an C<ArrayRef> or C<HashRef>. |

442 | =item I<trigger =E<gt> $code> |
443 | |
444 | The trigger option is a CODE reference which will be called after the value of |
445 | the attribute is set. The CODE ref will be passed the instance itself, the |
446 | updated value and the attribute meta-object (this is for more advanced fiddling |
cce8198b |
447 | and can typically be ignored in most cases). You can B<not> have a trigger on |
448 | a read-only attribute. |

450 | =item I<handles =E<gt> [ @handles ]> |
451 | |
452 | There is experimental support for attribute delegation using the C<handles> |
453 | option. More docs to come later. |

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

467 | =item B<super> |
468 | |
469 | The keyword C<super> is a noop when called outside of an C<override> method. In |
470 | the context of an C<override> method, it will call the next most appropriate |
471 | superclass method with the same arguments as the original method. |
472 | |
473 | =item B<override ($name, &sub)> |
474 | |
475 | An C<override> method, is a way of explictly saying "I am overriding this |
476 | method from my superclass". You can call C<super> within this method, and |
477 | it will work as expected. The same thing I<can> be accomplished with a normal |
478 | method call and the C<SUPER::> pseudo-package, it is really your choice. |
479 | |
480 | =item B<inner> |
481 | |
482 | The keyword C<inner>, much like C<super>, is a no-op outside of the context of |
483 | an C<augment> method. You can think of C<inner> as being the inverse of |
484 | C<super>, the details of how C<inner> and C<augment> work is best described in |
485 | the L<Moose::Cookbook>. |
486 | |
487 | =item B<augment ($name, &sub)> |
488 | |
489 | An C<augment> method, is a way of explictly saying "I am augmenting this |
490 | method from my superclass". Once again, the details of how C<inner> and |
491 | C<augment> work is best described in the L<Moose::Cookbook>. |
492 | |

493 | =item B<confess> |
494 | |
495 | This is the C<Carp::confess> function, and exported here beause I use it |
496 | all the time. This feature may change in the future, so you have been warned. |
497 | |
498 | =item B<blessed> |
499 | |
500 | This is the C<Scalar::Uti::blessed> function, it is exported here beause I |
501 | use it all the time. It is highly recommended that this is used instead of |
502 | C<ref> anywhere you need to test for an object's class name. |

506 | =head1 FUTURE PLANS |
507 | |
508 | Here is just a sampling of the plans we have in store for Moose: |
509 | |
510 | =over 4 |
511 | |
512 | =item * |
513 | |
514 | Compiling Moose classes/roles into C<.pmc> files for faster loading and execution. |
515 | |
516 | =item * |
517 | |
518 | Supporting sealed and finalized classes in Moose. This will allow greater control |
519 | of the extensions of frameworks and such. |
520 | |
521 | =back |
522 | |
523 | =head1 MISC. |
524 | |
525 | =head2 What does Moose stand for?? |
526 | |
527 | Moose doesn't stand for one thing in particular, however, if you |
528 | want, here are a few of my favorites, feel free to contribute |
529 | more :) |
530 | |
531 | =over 4 |
532 | |
533 | =item Make Other Object Systems Envious |
534 | |
535 | =item Makes Object Orientation So Easy |
536 | |
537 | =item Makes Object Orientation Spiffy- Er (sorry ingy) |
538 | |
539 | =item Most Other Object Systems Emasculate |
540 | |
2c0cbef7 |
541 | =item Moose Often Ovulate Sorta Early |
542 | |
2c0cbef7 |
543 | =item Moose Offers Often Super Extensions |
544 | |
545 | =item Meta Object Orientation Syntax Extensions |
546 | |
547 | =back |
548 | |

549 | =head1 CAVEATS |
550 | |
551 | =over 4 |
552 | |
553 | =item * |
554 | |
555 | It should be noted that C<super> and C<inner> can B<not> be used in the same |
556 | method. However, they can be combined together with the same class hierarchy, |
557 | see F<t/014_override_augment_inner_super.t> for an example. |
558 | |
559 | The reason that this is so is because C<super> is only valid within a method |
560 | with the C<override> modifier, and C<inner> will never be valid within an |
561 | C<override> method. In fact, C<augment> will skip over any C<override> methods |
562 | when searching for it's appropriate C<inner>. |
563 | |
564 | This might seem like a restriction, but I am of the opinion that keeping these |
565 | two features seperate (but interoperable) actually makes them easy to use since |
566 | their behavior is then easier to predict. Time will tell if I am right or not. |
