Hi,

I am using the Config::General module to be able to use a config file. But if a user does not set all options I want to be able to go back to a default value. How can I set these?

#!/usr/bin/env perl

use Getopt::Long;
use Config::General;

$PROGNAME = "myscript";

# Get Options from commandline
my $nodename;
usage() if ( @ARGV < 1 or ! GetOptions(
                "nodename=s"=>\$nodename
                ));

my $conf = new Config::General(
    -ConfigFile     => $PROGNAME . '.conf',
    -ExtendedAccess => 1
 );

&read_config;

sub read_config
 {
    if ($conf->is_hash($nodename))
    {
        $config = $conf->obj($nodename);
    }
    else
    {
        print "Critical error: No configuration list found for $nodena
+me\n";

    }
 }

The config look like this: 
<server1>
    host                = server1.domain.tld      
    ssl                 = true
    port                = 443
    username             = admin
    password             = qwerty
    vhost                = example
</server1>
<server2>
    host                = server2.domain.tld
    ssl                 = false
    port                = 2080    
    username             = admin
    password             = qwerty
    vhost                = example
</server2>

I want to check if a value exists to the config key and if not set a default one. But I cannot seem to figure out how.

So any pointers to a solution would be greatly appreciated!
