If I understand what you're asking for, you may want to have a look at
YAML.  Your config file can look like this:

####
adapter:   mysql
database:  demodb
username:  karl
password:  pa$$w0rd
socket:    /var/lib/mysql/mysql.sock
####

Turning that file into a ruby hash is a one-liner...

  require 'yaml'
  dbconfig = YAML::load(IO.read('config.yml'))
  assert_equal('karl', dbconfig[:username])
