NAME

Any::Moose - use Moose or Mouse modules

VERSION

version 0.18

SYNOPSIS

BASIC

    package Class;

    # uses Moose if it's loaded or demanded, Mouse otherwise
    use Any::Moose;

    # cleans the namespace up
    no Any::Moose;

OTHER MODULES

    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';

ROLES

    package My::Sorter;
    use Any::Moose 'Role';

    requires 'cmp';

COMPLEX USAGE

    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');

DESCRIPTION

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 Moose or Mouse.

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.

So, if you have to use Mouse, please be considerate to the Moose fanboys (like myself!) and use Any-Moose instead. :)

Mouse

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.
