Code

function date_ical_feeds_set_rrule($source, $entity, $target, $repeat_rule) {
  if (is_array($repeat_rule)) {

    // Newer versions of Feeds return $repeat_rule as an array containing the
    // string we returned from ParseVcalendar::parseRepeatProperty().
    $repeat_rule = reset($repeat_rule);
  }
  if (empty($repeat_rule)) {

    // Don't alter the entity if there's no repeat rule.
    return;
  }

  // $target looks like <field_name>:rrule, but we only need <field_name>.
  $field_name = current(explode(':', $target, 2));

  // Parse the repeat rule into RRULE, RDATE, EXRULE, and EXDATE strings.
  $repeat_data = array_combine(array(
    'RRULE',
    'RDATE',
    'EXRULE',
    'EXDATE',
  ), explode('|', $repeat_rule));
  module_load_include('inc', 'date_ical', 'date_ical.utils');

  // This "loop" is really just to make sure we get the right array keys. It
  // shouldn't ever execute more than once.
  foreach ($entity->{$field_name} as $lang => $date_values) {
    $values = _date_ical_get_repeat_dates($field_name, $repeat_data, $date_values[0], $source);
    foreach ($values as $key => $value) {
      $entity->{$field_name}[$lang][$key] = $value;
    }
  }
