MooseX::Getopt::Meta::Attribute

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

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.
