DBIx::Connect::FromConfig - Creates a DB connection from a configuration file
Version 0.04
use DBI;
use DBIx::Connect::FromConfig -in_dbi;
my $dbh = DBI->connect_from_config(config => $config);
# do DBI stuff
or, if you don't want to pollute DBI namespace:
use DBI;
use DBIx::Connect::FromConfig;
my $dbh = DBIx::Connect::FromConfig->connect(config => $config);
# do DBI stuff
DBIx::Connect::FromConfig provides a generic way to connect to a database using settings from a configuration object.
This module does not export any function, but if given the -in_dbi import option, it will install an alias of the connect() function in the DBI namespace, thus allowing it to be called as a method of DBI (see the synopsis).
Try to connect to a database using DBI and return the corresponding object.
Settings
driver - the name of the DBI driver for the database. This parameter is mandatory.database the name of the database. This parameter is mandatory.host - the hostname of the database. May be empty.port - the port of the database. May be empty.options - DBD options, given as a plain string.username - the user name used to connect to the database. Defaults to the current user.password - the password used to connect to the database. May be empty.Parameters
config - expects something that contains the settings:

Connect to a database, passing the settings in a plain hash reference:
my %settings = (
driver => 'Pg',
host => 'bigapp-db.society.com',
database => 'bigapp',
username => 'appuser',
password => 'sekr3t',
);
my $dbh = DBI->connect_from_config(config => \%settings);
Connect to a database, passing the settings from a configuration file:
my $config = Config::IniFiles->new(-file => '/etc/hebex/mail.conf');
my $dbh = DBI->connect_from_config(config => $config);
Database driver not specified(E) The setting specifying the database driver was not found or was empty.
Database driver %s not supported(E) The specified database driver is not supported by this module.
No parameter given(E) The function can't do anything if you don't give it the required arguments.
