NAME¶
MooseX::App::Plugin::MutexGroup - Adds mutually exclusive options
SYNOPSIS¶
In your base class:
package MyApp; use MooseX::App qw(MutexGroup); option 'UseAmmonia' => ( is => 'ro', isa => 'Bool', mutexgroup => 'NonMixableCleaningChemicals', ); option 'UseChlorine' => ( is => 'ro', isa => 'Bool', mutexgroup => 'NonMixableCleaningChemicals' );
In your script:
#!/usr/bin/env perl use strict; use warnings; use MyApp; MyApp->new_with_options( UseAmmonia => 1, UseChlorine => 1 ); # generates Error # More than one attribute from mutexgroup NonMixableCleaningChemicals('UseAmmonia','UseChlorine') *cannot* be specified MyApp->new_with_options(); # generates Error # One attribute from mutexgroup NonMixableCleaningChemicals('UseAmmonia','UseChlorine') *must* be specified MyApp->new_with_options( UseAmmonia => 1 ); # generates no errors MyApp->new_with_options( UseChlorine => 1 ); # generates no errors
DESCRIPTION¶
This plugin adds mutually exclusive options to your application. In the current implementation, all defined MutexGroups *must* have exactly one initialized option. This means that there is an implicit requiredness of one option from each MutexGroup.
