NAME MooX::Enumeration - shortcuts for working with enum attributes in Moo SYNOPSIS Given this class: package MyApp::Result { use Moo; use Types::Standard qw(Enum); has status => ( is => "rw", isa => Enum[qw/ pass fail /], ); } It's quite common to do this kind of thing: if ( $result->status eq "pass" ) { ... } But if you're throwing strings around, it can be quite easy to mistype them: if ( $result->status eq "apss" ) { ... } And the comparison silently fails. Instead, let's define the class like this: package MyApp::Result { use Moo; use MooX::Enumeration; use Types::Standard qw(Enum); has status => ( is => "rw", isa => Enum[qw/ pass fail /], handles => [qw/ is_pass is_fail /], ); } So you can use the class like this: if ( $result->is_pass ) { ... } Yay! DESCRIPTION This is a Moo implementation of MooseX::Enumeration. All the features from the Moose version should work here. Passing `traits => ["Enumeration"]` to `has` is not needed with MooX::Enumeration. This module's magic is automatically applied to all attributes with a Type::Tiny::Enum type constraint. Simple example: package MyClass { use Moo; use MooX::Enumeration; has xyz => (is => "ro", enum => [qw/foo bar baz/], handles => 1); } `MyClass->new(xyz => "quux")` will throw an error. Objects of the class will have `$object->is_foo`, `$object->is_bar`, and `$object->is_baz` methods. For more details of method delegation, see MooseX::Enumeration. BUGS Please report any bugs to .
