295 | =head1 DESCRIPTION |
296 | |
e522431d |
297 | Moose is an extension of the Perl 5 object system. |
298 | |
299 | =head2 Another object system!?!? |
fcd84ca9 |
300 | |
e522431d |
301 | Yes, I know there has been an explosion recently of new ways to |
68efb014 |
302 | build object's in Perl 5, most of them based on inside-out objects |
e522431d |
303 | and other such things. Moose is different because it is not a new |
304 | object system for Perl 5, but instead an extension of the existing |
305 | object system. |
3c7278fb |
306 | |
e522431d |
307 | Moose is built on top of L<Class::MOP>, which is a metaclass system |
308 | for Perl 5. This means that Moose not only makes building normal |
505c6fac |
309 | Perl 5 objects better, but it also provides the power of metaclass |
310 | programming. |
e522431d |
311 | |
734d1752 |
312 | =head2 Is this for real? Or is this just an experiment? |
e522431d |
313 | |
2c0cbef7 |
314 | Moose is I<based> on the prototypes and experiments I did for the Perl 6 |
68efb014 |
315 | meta-model; however Moose is B<NOT> an experiment/prototype, it is |
734d1752 |
316 | for B<real>. |
317 | |
d44714be |
318 | =head2 Is this ready for use in production? |
319 | |
320 | Yes, I believe that it is. |
734d1752 |
321 | |
322 | I have two medium-to-large-ish web applications which use Moose heavily |
323 | and have been in production (without issue) for several months now. At |
324 | $work, we are re-writing our core offering in it. And several people on |
325 | #moose have been using it (in production) for several months now as well. |
e522431d |
326 | |
d44714be |
327 | Of course, in the end, you need to make this call yourself. If you have |
328 | any questions or concerns, please feel free to email me, or even the list |
329 | or just stop by #moose and ask away. |
330 | |
43d599e5 |
331 | =head2 Is Moose just Perl 6 in Perl 5? |
e522431d |
332 | |
68efb014 |
333 | No. While Moose is very much inspired by Perl 6, it is not itself Perl 6. |
334 | Instead, it is an OO system for Perl 5. I built Moose because I was tired or |
335 | writing the same old boring Perl 5 OO code, and drooling over Perl 6 OO. So |
336 | instead of switching to Ruby, I wrote Moose :) |
3c7278fb |
337 | |
6ba6d68c |
338 | =head1 BUILDING CLASSES WITH MOOSE |
339 | |
68efb014 |
340 | Moose makes every attempt to provide as much convenience as possible during |
341 | class construction/definition, but still stay out of your way if you want it |
342 | to. Here are a few items to note when building classes with Moose. |
6ba6d68c |
343 | |
344 | Unless specified with C<extends>, any class which uses Moose will |
345 | inherit from L<Moose::Object>. |
346 | |
347 | Moose will also manage all attributes (including inherited ones) that |
68efb014 |
348 | are defined with C<has>. And assuming that you call C<new>, which is |
6ba6d68c |
349 | inherited from L<Moose::Object>, then this includes properly initializing |
68efb014 |
350 | all instance slots, setting defaults where appropriate, and performing any |
6ba6d68c |
351 | type constraint checking or coercion. |
352 | |
353 | =head1 EXPORTED FUNCTIONS |
354 | |
68efb014 |
355 | Moose will export a number of functions into the class's namespace which |
6ba6d68c |
356 | can then be used to set up the class. These functions all work directly |
357 | on the current class. |
358 | |
359 | =over 4 |
360 | |
361 | =item B<meta> |
362 | |
363 | This is a method which provides access to the current class's metaclass. |
364 | |
365 | =item B<extends (@superclasses)> |
366 | |
367 | This function will set the superclass(es) for the current class. |
368 | |
369 | This approach is recommended instead of C<use base>, because C<use base> |
370 | actually C<push>es onto the class's C<@ISA>, whereas C<extends> will |
371 | replace it. This is important to ensure that classes which do not have |
68efb014 |
372 | superclasses still properly inherit from L<Moose::Object>. |
6ba6d68c |
373 | |
43d599e5 |
374 | =item B<with (@roles)> |
e9ec68d6 |
375 | |
43d599e5 |
376 | This will apply a given set of C<@roles> to the local class. Role support |
68efb014 |
377 | is currently under heavy development; see L<Moose::Role> for more details. |
e9ec68d6 |
378 | |
6ba6d68c |
379 | =item B<has ($name, %options)> |
380 | |
381 | This will install an attribute of a given C<$name> into the current class. |
43d599e5 |
382 | The list of C<%options> are the same as those provided by |
383 | L<Class::MOP::Attribute>, in addition to the list below which are provided |
384 | by Moose (L<Moose::Meta::Attribute> to be more specific): |
6ba6d68c |
385 | |
386 | =over 4 |
387 | |
076c81ed |
388 | =item I<is =E<gt> 'rw'|'ro'> |
6ba6d68c |
389 | |
390 | The I<is> option accepts either I<rw> (for read/write) or I<ro> (for read |
391 | only). These will create either a read/write accessor or a read-only |
392 | accessor respectively, using the same name as the C<$name> of the attribute. |
393 | |
394 | If you need more control over how your accessors are named, you can use the |
43d599e5 |
395 | I<reader>, I<writer> and I<accessor> options inherited from L<Class::MOP::Attribute>. |
6ba6d68c |
396 | |
076c81ed |
397 | =item I<isa =E<gt> $type_name> |
6ba6d68c |
398 | |
399 | The I<isa> option uses Moose's type constraint facilities to set up runtime |
400 | type checking for this attribute. Moose will perform the checks during class |
401 | construction, and within any accessors. The C<$type_name> argument must be a |
68efb014 |
402 | string. The string can be either a class name or a type defined using |
403 | Moose's type definition features. |
6ba6d68c |
404 | |
daea75c9 |
405 | =item I<coerce =E<gt> (1|0)> |
406 | |
407 | This will attempt to use coercion with the supplied type constraint to change |
68efb014 |
408 | the value passed into any accessors or constructors. You B<must> have supplied |
daea75c9 |
409 | a type constraint in order for this to work. See L<Moose::Cookbook::Recipe5> |
410 | for an example usage. |
411 | |
412 | =item I<does =E<gt> $role_name> |
413 | |
414 | This will accept the name of a role which the value stored in this attribute |
415 | is expected to have consumed. |
416 | |
417 | =item I<required =E<gt> (1|0)> |
418 | |
419 | This marks the attribute as being required. This means a value must be supplied |
420 | during class construction, and the attribute can never be set to C<undef> with |
421 | an accessor. |
422 | |
423 | =item I<weak_ref =E<gt> (1|0)> |
424 | |
68efb014 |
425 | This will tell the class to store the value of this attribute as a weakened |
426 | reference. If an attribute is a weakened reference, it B<cannot> also be |
427 | coerced. |
daea75c9 |

429 | =item I<lazy =E<gt> (1|0)> |

431 | This will tell the class to not create this slot until absolutely necessary. |

9e93dd19 |
434 | =item I<auto_deref =E<gt> (1|0)> |
435 | |
68efb014 |
436 | This tells the accessor whether to automatically dereference the value returned. |
9e93dd19 |
437 | This is only legal if your C<isa> option is either an C<ArrayRef> or C<HashRef>. |
438 | |

439 | =item I<trigger =E<gt> $code> |
440 | |
441 | The trigger option is a CODE reference which will be called after the value of |
442 | the attribute is set. The CODE ref will be passed the instance itself, the |
443 | updated value and the attribute meta-object (this is for more advanced fiddling |
68efb014 |
444 | and can typically be ignored in most cases). You B<cannot> have a trigger on |
cce8198b |
445 | a read-only attribute. |

450 | option. More docs to come later. |

464 | =item B<super> |
465 | |
68efb014 |
466 | The keyword C<super> is a no-op when called outside of an C<override> method. In |
159da176 |
467 | the context of an C<override> method, it will call the next most appropriate |
468 | superclass method with the same arguments as the original method. |
469 | |
470 | =item B<override ($name, &sub)> |
471 | |
68efb014 |
472 | An C<override> method is a way of explicitly saying "I am overriding this |
159da176 |
473 | method from my superclass". You can call C<super> within this method, and |
474 | it will work as expected. The same thing I<can> be accomplished with a normal |
68efb014 |
475 | method call and the C<SUPER::> pseudo-package; it is really your choice. |
159da176 |
476 | |
477 | =item B<inner> |
478 | |
479 | The keyword C<inner>, much like C<super>, is a no-op outside of the context of |
480 | an C<augment> method. You can think of C<inner> as being the inverse of |
68efb014 |
481 | C<super>; the details of how C<inner> and C<augment> work is best described in |
159da176 |
482 | the L<Moose::Cookbook>. |
483 | |
484 | =item B<augment ($name, &sub)> |
485 | |
68efb014 |
486 | An C<augment> method, is a way of explicitly saying "I am augmenting this |
159da176 |
487 | method from my superclass". Once again, the details of how C<inner> and |
488 | C<augment> work is best described in the L<Moose::Cookbook>. |

6ba6d68c |
490 | =item B<confess> |
491 | |
68efb014 |
492 | This is the C<Carp::confess> function, and exported here because I use it |
6ba6d68c |
493 | all the time. This feature may change in the future, so you have been warned. |
494 | |
495 | =item B<blessed> |
496 | |
68efb014 |
497 | This is the C<Scalar::Uti::blessed> function, it is exported here because I |
6ba6d68c |
498 | use it all the time. It is highly recommended that this is used instead of |
499 | C<ref> anywhere you need to test for an object's class name. |

503 | =head1 UNEXPORTING FUNCTIONS |
504 | |
505 | =head2 B<unimport> |
506 | |
507 | Moose offers a way of removing the keywords it exports though the C<unimport> |
508 | method. You simply have to say C<no Moose> at the bottom of your code for this |
509 | to work. Here is an example: |
510 | |
511 | package Person; |
512 | use Moose; |
513 | |
514 | has 'first_name' => (is => 'rw', isa => 'Str'); |
515 | has 'last_name' => (is => 'rw', isa => 'Str'); |
516 | |
517 | sub full_name { |
518 | my $self = shift; |
519 | $self->first_name . ' ' . $self->last_name |
520 | } |
521 | |
522 | no Moose; # keywords are removed from the Person package |
523 | |

526 | =head2 What does Moose stand for?? |
527 | |
528 | Moose doesn't stand for one thing in particular, however, if you |
68efb014 |
529 | want, here are a few of my favorites; feel free to contribute |

554 | =item * |
555 | |
68efb014 |
556 | It should be noted that C<super> and C<inner> C<cannot> be used in the same |
557 | method. However, they can be combined together with the same class hierarchy; |
05d9eaf6 |
558 | see F<t/014_override_augment_inner_super.t> for an example. |
559 | |
68efb014 |
560 | The reason for this is that C<super> is only valid within a method |
05d9eaf6 |
561 | with the C<override> modifier, and C<inner> will never be valid within an |
562 | C<override> method. In fact, C<augment> will skip over any C<override> methods |
68efb014 |
563 | when searching for its appropriate C<inner>. |
05d9eaf6 |
564 | |
565 | This might seem like a restriction, but I am of the opinion that keeping these |
68efb014 |
566 | two features separate (but interoperable) actually makes them easy to use, since |
05d9eaf6 |
567 | their behavior is then easier to predict. Time will tell if I am right or not. |
