MooseX::Getopt::Meta::Attribute::Trait - Optional meta attribute trait for custom option names

SYNOPSIS

Top

  package App;
  use Moose;

  with 'MooseX::Getopt';

  has 'data' => (
      traits    => [ 'Getopt' ],
      is        => 'ro',
      isa       => 'Str',
      default   => 'file.dat',

      # tells MooseX::Getopt to use --somedata as the
      # command line flag instead of the normal
      # autogenerated one (--data)
      cmd_flag  => 'somedata',

      # tells MooseX::Getopt to also allow --moosedata,
      # -m, and -d as aliases for this same option on
      # the commandline.
      cmd_aliases => [qw/ moosedata m d /],

      # Or, you can use a plain scalar for a single alias:
      cmd_aliases => 'm',
  );

DESCRIPTION
