Getopt::Helpful Description

Getopt::Helpful is an integrated option hash / help messages. Getopt::Helpful is an integrated option hash / help messages.STATEThis module is still under development, but is being publish on CPAN to satisfy some code which depends on it. The interface may change in a future version and some of the functionality is not yet complete.SYNOPSISThis module provides methods which integrate help messages into a Getopt::Long option spec. This gathers documentation and declaration into one place and allows you to utilize perl code to state the default values of options in your online help messages (helping you utilize the single-point-of-truth principle.)Additionally, it provides DWIM methods (Get) which allow you to cut some standard error-checking code from your scripts. There is even a handy usage() method which eliminates that silly block of code from the beginning. #!/usr/bin/perl use warnings; use strict; use Getopt::Helpful; my $var1 = "default"; my $req_arg; # declare this as 'our' or $main::verbose our $verbose = 0; # every option must be passed into the constructor... my $hopt = Getopt::Helpful->new( usage => 'CALLER ', , , '+verbose', '+help', ); # call GetOptions() behind the scenes (with error-checking) $hopt->Get(); $req_arg or ($req_arg = shift); # usage() called with a message results in non-zero exit code $req_arg or $hopt->usage('missing required argument'); $verbose and warn "doing stuff nown"; # now do stuff...Requirements:· Perl Requirements: · Perl
