378 | =head2 SYNOPSIS |
379 | |
380 | use Mouse::Util::TypeConstraints; |
381 | |
382 | subtype 'Natural' |
383 | => as 'Int' |
384 | => where { $_ > 0 }; |
385 | |
386 | subtype 'NaturalLessThanTen' |
387 | => as 'Natural' |
388 | => where { $_ < 10 } |
389 | => message { "This number ($_) is not less than ten!" }; |
390 | |
391 | coerce 'Num' |
392 | => from 'Str' |
393 | => via { 0+$_ }; |
394 | |
395 | enum 'RGBColors' => qw(red green blue); |
396 | |
397 | no Mouse::Util::TypeConstraints; |
398 | |
399 | =head1 DESCRIPTION |
400 | |
401 | This module provides Mouse with the ability to create custom type |
402 | constraints to be used in attribute definition. |
403 | |
404 | =head2 Important Caveat |
405 | |
406 | This is B<NOT> a type system for Perl 5. These are type constraints, |
407 | and they are not used by Mouse unless you tell it to. No type |
408 | inference is performed, expressions are not typed, etc. etc. etc. |
409 | |
410 | A type constraint is at heart a small "check if a value is valid" |
411 | function. A constraint can be associated with an attribute. This |
412 | simplifies parameter validation, and makes your code clearer to read, |
413 | because you can refer to constraints by name. |
414 | |
415 | =head2 Slightly Less Important Caveat |
416 | |
417 | It is B<always> a good idea to quote your type names. |
418 | |
419 | This prevents Perl from trying to execute the call as an indirect |
420 | object call. This can be an issue when you have a subtype with the |
421 | same name as a valid class. |
422 | |
423 | For instance: |
424 | |
425 | subtype DateTime => as Object => where { $_->isa('DateTime') }; |
426 | |
427 | will I<just work>, while this: |
428 | |
429 | use DateTime; |
430 | subtype DateTime => as Object => where { $_->isa('DateTime') }; |
431 | |
432 | will fail silently and cause many headaches. The simple way to solve |
433 | this, as well as future proof your subtypes from classes which have |
434 | yet to have been created, is to quote the type name: |
435 | |
436 | use DateTime; |

439 | =head2 Default Type Constraints |
440 | |
441 | This module also provides a simple hierarchy for Perl 5 types, here is |
442 | that hierarchy represented visually. |
443 | |
dba2e142 |
444 | Any |
5893ee36 |
445 | Item |
446 | Bool |
447 | Maybe[`a] |
448 | Undef |
449 | Defined |
450 | Value |
5893ee36 |
451 | Str |
dba2e142 |
452 | Num |
453 | Int |
454 | ClassName |
455 | RoleName |
5893ee36 |
456 | Ref |
457 | ScalarRef |
458 | ArrayRef[`a] |
459 | HashRef[`a] |
460 | CodeRef |
461 | RegexpRef |
462 | GlobRef |
dba2e142 |
463 | FileHandle |
5893ee36 |
464 | Object |
5893ee36 |
465 | |
466 | B<NOTE:> Any type followed by a type parameter C<[`a]> can be |
467 | parameterized, this means you can say: |
468 | |
469 | ArrayRef[Int] # an array of integers |
470 | HashRef[CodeRef] # a hash of str to CODE ref mappings |
471 | Maybe[Str] # value may be a string, may be undefined |
472 | |
473 | If Mouse finds a name in brackets that it does not recognize as an |
474 | existing type, it assumes that this is a class name, for example |
475 | C<ArrayRef[DateTime]>. |
476 | |
477 | B<NOTE:> Unless you parameterize a type, then it is invalid to include |
478 | the square brackets. I.e. C<ArrayRef[]> will be treated as a new type |
479 | name, I<not> as a parameterization of C<ArrayRef>. |
480 | |
481 | B<NOTE:> The C<Undef> type constraint for the most part works |
482 | correctly now, but edge cases may still exist, please use it |
483 | sparingly. |
484 | |
485 | B<NOTE:> The C<ClassName> type constraint does a complex package |
486 | existence check. This means that your class B<must> be loaded for this |
487 | type constraint to pass. |
488 | |
489 | B<NOTE:> The C<RoleName> constraint checks a string is a I<package |
490 | name> which is a role, like C<'MyApp::Role::Comparable'>. The C<Role> |
491 | constraint checks that an I<object does> the named role. |
492 | |
493 | =head2 Type Constraint Naming |
494 | |
495 | Type name declared via this module can only contain alphanumeric |
496 | characters, colons (:), and periods (.). |
497 | |
498 | Since the types created by this module are global, it is suggested |
499 | that you namespace your types just as you would namespace your |
500 | modules. So instead of creating a I<Color> type for your |
501 | B<My::Graphics> module, you would call the type |
502 | I<My::Graphics::Types::Color> instead. |
503 | |
504 | =head2 Use with Other Constraint Modules |
505 | |
506 | This module can play nicely with other constraint modules with some |
507 | slight tweaking. The C<where> clause in types is expected to be a |
508 | C<CODE> reference which checks it's first argument and returns a |
509 | boolean. Since most constraint modules work in a similar way, it |
510 | should be simple to adapt them to work with Mouse. |
511 | |
512 | For instance, this is how you could use it with |
513 | L<Declare::Constraints::Simple> to declare a completely new type. |
514 | |
515 | type 'HashOfArrayOfObjects', |
516 | { |
517 | where => IsHashRef( |
518 | -keys => HasLength, |
519 | -values => IsArrayRef(IsObject) |
520 | ) |
521 | }; |
522 | |
523 | Here is an example of using L<Test::Deep> and it's non-test |
524 | related C<eq_deeply> function. |
525 | |
526 | type 'ArrayOfHashOfBarsAndRandomNumbers' |
527 | => where { |
528 | eq_deeply($_, |
529 | array_each(subhashof({ |
530 | bar => isa('Bar'), |
531 | random_number => ignore() |
532 | }))) |
533 | }; |
