NAME Getopt::Inherited - Handling inherited command-line options VERSION version 1.100860 SYNOPSIS use base 'Getopt::Inherited'; use constant GETOPT => qw(foo=s); my $app = __PACKAGE__->new; $app->do_getopt; DESCRIPTION By subclassing this mixin class, your program gets the ability to inherit command-line option specifications. If you have several programs that share common code and common command-line options you don't want to have to write the command-line processing code again and again. Using this class you can abstract command-line options shared by your programs into a superclass from which your programs then inherit. Additionally, this class defines certain common command-line options itself. You can also define defaults for command-line options. METHODS GETOPT This accessor, which is accumulated across the class hierarchy using Data::Inherited, is used to define command-line options in the same format as Getopt::Long expects. This class, Getopt::Inherited, itself defines the following options: use constant GETOPT => (qw(help man logfile|log=s verbose|v+ version|V)); GETOPT_DEFAULTS This accessor, which is also accumulated across the class hierarchy, can be used to define defaults for the options given in "GETOPT()". For example, to define a command-line option called which takes a string and to give it a default, you would use: use constant GETOPT => qw(foo=s); use constant GETOPT_DEFAULTS => (foo => 'my_default'); opt This is a hash accessor per Class::Accessor::Complex in which the option hash is stored when it has been parsed and after default values have been applied. usage This method is called by "do_getopt()" after the command-line options have been processed with Getopt::Long's "GetOptions". It uses Pod::Usage to display help information if there was either an error during processing, or if the "--help" or "--man" options have been given. do_getopt Does the actual command-line processing. It accumulates the values of GETOPT() across the hierarchy, parses them, calls "usage()" if necessary, applies GETOPT_DEFAULTS(), then assigns the finished options hash to "opt()".
