getopt::long::descriptive::usage
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 0.092 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.
