App::Cmdline::Options::Basic - set of basic options for command-line applications


version 0.1.2


   # In your module that represents a command-line application:
   sub opt_spec {
       my $self = shift;
       return $self->check_for_duplicates (
           [ 'check|c' => "only check the configuration"  ],
           $self->composed_of (
               'App::Cmdline::Options::Basic',  # here are the basic options added
               'App::Cmdline::Options::DB',     # here may be other options


This is a kind of a role module, defining a particular set of command-line options and their validation. See more about how to write a module that represents a command-line application and that uses this set of options in App::Cmdline.


Particularly, this module specifies the basic options, usually used by any command-line application:

    [ 'h'         => "display a short usage message"  ],
    [ 'version|v' => "display a version"              ],


It prints a short usage message, something like this:

   Usage: myapp [non-bundled short or long options]
        -h             display a short usage message
        -v --version   display a version


It print the version of the application and exits in one of the two possible ways: If it is called from and eval expression, it dies (so you can catch it and continue). Otherwise, it exists with the exit code zero.
