NAME

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

VERSION

       version 0.76

SYNOPSIS

         package App;
         use Moose;

         with 'MooseX::Getopt';

         has 'data' => (
             metaclass => '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

       This is a custom attribute metaclass which can be used to specify a the specific command line flag to use
       instead of the default one which MooseX::Getopt will create for you.

       This is certainly not the prettiest way to go about this, but for now it works for those who might need
       such a feature.

   Use 'traits' instead of 'metaclass'
       You should rarely need to explicitly set the attribute metaclass. It is much preferred to simply provide
       a trait (a role applied to the attribute metaclass), which allows other code to further modify the
       attribute by applying additional roles.

       Therefore, you should first try to do this:

         has 'foo' => (traits => ['Getopt'], cmd_flag => 'f');

   Custom Metaclass alias
       This now takes advantage of the Moose 0.19 feature to support custom attribute metaclass aliases. This
       means you can also use this as the Getopt alias, like so:

         has 'foo' => (metaclass => 'Getopt', cmd_flag => 'f');

METHODS

   cmd_flag
       Changes the command-line flag to be this value, instead of the default, which is the same as the
       attribute name.

   cmd_aliases
       Adds more aliases for this command-line flag, useful for short options and such.
