Any::Moose - *deprecated* - use Moo instead!
package Class; # uses Moose if it's loaded or demanded, Mouse otherwise use Any::Moose; # cleans the namespace up no Any::Moose;
package Other::Class; use Any::Moose; # uses Moose::Util::TypeConstraints if the class has loaded Moose, # Mouse::Util::TypeConstraints otherwise. use Any::Moose '::Util::TypeConstraints';
package My::Sorter; use Any::Moose 'Role'; requires 'cmp';
package My::Meta::Class; use Any::Moose; # uses subtype from Moose::Util::TypeConstraints if the class loaded Moose, # subtype from Mouse::Util::TypeConstraints otherwise. # similarly for Mo*se::Util's does_role use Any::Moose ( '::Util::TypeConstraints' => ['subtype'], '::Util' => ['does_role'], ); # uses MouseX::Types or MooseX::Types use Any::Moose 'X::Types'; # gives you the right class name depending on which Mo*se was loaded extends any_moose('::Meta::Class');
Though we recommend that people generally use Moose, we accept that Moose cannot yet be used for everything everywhere. People generally like the Moose sugar, so many people use Mouse, a lightweight replacement for parts of Moose.
Because Mouse strives for compatibility with Moose, it's easy to substitute one for the other. This module facilitates that substitution. By default, Mouse will be provided to libraries, unless Moose is already loaded -or- explicitly requested by the end-user. The end-user can force the decision of which backend to use by setting the environment variable
ANY_MOOSE to be
Note that the decision of which backend to use is made only once, so that if Any-Moose picks Mouse, then a third-party library loads Moose, anything else that uses Any-Moose will continue to pick Mouse.
Please use Moo instead of Any::Moose for new code.
Moo classes and roles will transparently and correctly upgrade to Moose when needed. This is a fundamentally better design than what Any::Moose offers. Mouse metaclasses do not interact with Moose metaclasses which leaks abstractions all over the place.
Any::Moose had a good run. It was a simplistic but expedient answer for getting Moose syntax on the cheap but with the transparent upgrade path to Moose when you needed it. But really, please don't use it any more. :)
You may find MooX::late useful for porting your code from Any::Moose to Moo.
Squirrel - a deprecated first-stab at Any-Moose-like logic. Its biggest fault was in making the decision of which backend to use every time it was used, rather than just once.
