MooseX::Getopt::Dashes(3pm)				User Contributed Perl Documentation			       MooseX::Getopt::Dashes(3pm)

NAME

       MooseX::Getopt::Dashes - convert underscores in attribute names to dashes

VERSION

       version 0.59

SYNOPSIS

	 package My::App;
	 use Moose;
	 with 'MooseX::Getopt::Dashes';

	 # Will be called as --some-thingy, not --some_thingy
	 has 'some_thingy' => (
	     is      => 'ro',
	     isa     => 'Str',
	     default => 'foo'
	 );

	 # Will be called as --another_thingy, not --another-thingy
	 has 'another_thingy' => (
	     traits   => [ 'Getopt' ],
	     cmd_flag => 'another_thingy'
	     is       => 'ro',
	     isa      => 'Str',
	     default  => 'foo'
	 );

	 # use as MooseX::Getopt

DESCRIPTION

       This is a version of "MooseX::Getopt" which converts underscores in attribute names to dashes when generating command line flags.

       You can selectively disable this on a per-attribute basis by supplying a cmd_flag argument with the command flag you'd like for a given
       attribute. No underscore to dash replacement will be done on the "cmd_flag".
