Getopt::Long::Descriptive::Usage(3)  User Contributed Perl Documentation Getopt::Long::Descriptive::Usage(3)



NAME
       Getopt::Long::Descriptive::Usage - the usage description for GLD

VERSION
       version 0.090

SYNOPSIS
         use Getopt::Long::Descriptive;
         my ($opt, $usage) = describe_options( ... );

         $usage->text; # complete usage message

         $usage->die;  # die with usage message

DESCRIPTION
       This document only describes the methods of the Usage object.  For information on how to use
       Getopt::Long::Descriptive, consult its documentation.

METHODS
   new
         my $usage = Getopt::Long::Descriptive::Usage->new(\%arg);

       You really don't need to call this.  GLD will do it for you.

       Valid arguments are:

         options     - an arrayref of options
         leader_text - the text that leads the usage; this may go away!

   text
       This returns the full text of the usage message.

   leader_text
       This returns the text that comes at the beginning of the usage message.

   option_text
       This returns the text describing the available options.

   warn
       This warns with the usage message.

   die
       This throws the usage message as an exception.

         $usage_obj->die(\%arg);

       Some arguments can be provided

         pre_text  - text to be prepended to the usage message
         post_text - text to be appended to the usage message

       The "pre_text" and "post_text" arguments are concatenated with the usage message with no line breaks,
       so supply this if you need them.
