Dear Masters,
Here is a code which use Getopt::Long to produce a help instruction. As can be seen below, I also want my code to print out the help message when no argument is passed.
Thus, what I generally do is to use print command and pass them as subroutine
usage().
I want to use POD instead of print method I have now.
My question is how can I pass a POD construct into a subroutine?
#!/usr/bin/perl -w
use strict;
use Data::Dumper;
use Getopt::Long;
use Pod::Usage;
my $some_param = 5; #Default value
my $help = 0;
if ( @ARGV == 0 ) {
&usage();
exit(1);
}
my $res = GetOptions (
"someparam|s=s"=>\$some_param,
"help"=> \$help,
);
&usage() if ($help);
if ($res) {
# Do sth with param
print "PARAM IS: $some_param\n";
}
sub usage {
print <<HELP;
mycode.pl version 1.00

Usage: perl $0 [-options]
Options are:
-h Print this help
-s Some param
HELP
exit;
}
I'm at lost with this construct:
sub_usage_pod {
=head1 NAME
MYCODE - do something
=head1 SYNOPSIS
sample [options] [file ...]
Options:
-help brief help message
-s Some param
-man full documentation
=head1 OPTIONS
=over 8
=item B<-help>
Print a brief help message and exits.
=item B<-man>
Prints the manual page and exits.
=back

}
