DESCRIPTION

41       Provides some extra markup to help MooseX::Role::Cmd decide how to use
42       command line parameters.
43

ATTRIBUTES

45   cmdopt_prefix
46       Forces the command prefix to be a certain character. This was
47       introduced to allow parameters to be specified as "-param" or "--param"
48
49   has_cmdopt_prefix
50       Test for attribute above
51
52   cmdopt_name
53       Forces the command options name to be the passed string. This was
54       introduced to allow parameters to have a different name to the
55       attribute.
56
57       This option will override the cmdopt_prefix attribute.
58
59   has_cmdopt_name
60       Test for attribute above
61
62   cmdopt_env
63       This attribute trait can be used to specify an environment variable
64       rather than a command line option.
65
66           has 'home_dir' => (
67               traits => [ 'CmdOpt' ],
68               is => 'rw',
69               isa => 'Str',
70               cmdopt_env => 'APP_HOME',
71               default => '/my/app/home'
72           );
73
74           # $ENV{APP_HOME} = /my/app/home
75
76   has_cmdopt_env
77       Test for attribute above
