Perl, How to Load parameters from config file

Posted: Tue, Apr 26 07:27 AM (PDT)

The easy solution for Perl to have any configuration parameters of your application in a file

#!/usr/bin/perl

my %config = load_config("/etc/perl_application.conf");

sub load_config {
        my $conf_name = $_[0];
        my %config = {};
        open(CFG, "<".$conf_name);
        while() {
                chomp;
                my ($var, $val) = split(/\s*\=\s*/);
                if ($val eq 'true') { $config{$var} = true; }
                if ($val eq 'false') { $config{$var} = false; }
                if (($var=~/^\#/is) || ($var eq '')) { } else { $config{$var} = $val; }
        }
        close(CFG);

# Dump config file

        foreach my $key (keys %config) {
        if ($key=~/^HASH/is) { } else {
                      print $key.": ".$config{$key}."\n";
              }
        }
        return %config;
}

perl_application.conf

# MongoDB Settings
mongo_host = 127.0.0.1
mongo_port = 27017
mongo_database = atlas365
mongo_auth = false

# MySQL Settings
mysql_host = 127.0.0.1
mysql_port = 3306
mysql_database = atlas365
mysql_username = mysqlusr
