App::Cmdline::Options::ExtDB - extended set of database-related 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::ExtDB',  # here are the database options added
               'App::Cmdline::Options::Basic',  # 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 extends the basic database-related options, adding an option for showing how the database options have been set. It inherits from App::Cmdline::Options::DB module, and, therefore, provides the same options defined there, and it adds the following option:

    [ 'dbshow' => "show database access properties"  ],


It prints (on STDOUT) values given to the database-related options. For example:

   senger@ShereKhan2:myapp --dbshow --dbname Emma --dbpasswd vrrr -dbhost
   DBNAME: Emma
   DBPORT: 3306
   DBUSER: reader
   DBPASS: ...given but not shown
   DBSOCK: n/a
