Data Dumper to print out hash values Can't Post
Can you tell me how to use Data Dumper to print out the values in the hashes in the code below.


#!/usr/bin/perl -w

use strict;
use App::Options (
options => [ qw(dbhost dbusername dbpassword homepage legacy) ],
option => {
storefront => {
description => "storefront location",
},
homepage => {
default => "/usr/local/apache/htdocs/",
},
legacy => {
default => "/usr/local/apache/htdocs/dir",

},
);

use Data::Dumper;

Hi,

Code
use Data::Dumper;  
# ... 
print Dumper %hash; 
# or, better 
print Dumper $hash_ref; # $hash_ref being a reference to the hash

But you did not declare any hash, did you?

Well what I'm trying to do is print the value in storefront, homepage, legacy, and options. How do I do that?

Well, I would suppose that the App::Options probably has a method (or function) to do that.

Else, you could probably peek into the code of this module to figure out the name of the hash where it probably stores these values, but that would be very bad practice, you are really not supposed to do that.

This is just all learning and practice for me. How would I like at the code of this module?
