this works ..

scala> :paste
// Entering paste mode (ctrl-D to finish)

"database:[table1,table2]" match {
  case r"""(\w+)$d(:\[(\w+)$f(,(\w+)$x)*$y\])?$t""" => (d, f, x, y, t)
  case _ => "no match"
}

// Exiting paste mode, now interpreting.

res29: java.io.Serializable = (database,:[table1,table2],table1,,table2,table2)
