NAME ^

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

SYNOPSIS ^

  package App;
  use Moose;
  
  with 'MooseX::Getopt';
  
  has 'data' => (
      metaclass => 'MooseX::Getopt::Meta::Attribute',     
      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.

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 ^

These methods are of little use to most users, they are used interally within MooseX::Getopt.

cmd_flag

Changes the commandline flag to be this value, instead of the default, which is the same as the attribute name.

cmd_aliases

Adds more aliases for this commandline flag, useful for short options and such.
