MooseX::Getopt::Meta::UseriContributed Perl MooseX::Getopt::Meta::Attribute(3)

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

VERSION
       version 0.71

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.
