File

./date_ical.module, line 205

Adds ical functionality to Views, and an iCal parser to Feeds.

Code

function date_ical_sanitize_text($text = '') {

  // Use Drupal's built-in HTML to Text converter, which does a mostly adequate
  // job of making the text iCal-compliant.
  $text = trim(drupal_html_to_text($text));

  // Replace instances of more than one space with exactly one space. This
  // cleans up the whitespace mess that gets left behind by drupal_html_to_text().
  $text = preg_replace("/  +/", " ", $text);

  // The call to drupal_html_to_text() above converted <p> to \n\n, and also
  // shoved a \n into the string every 80 characters. We don't want those
  // single \n's lying around, because iCalcreator will properly "fold" long
  // text fields for us. So, we need to remove all instances of \n which
  // are neither immediately preceeded, nor followed, by another \n.
  $text = preg_replace("/(?<!\n)\n(?!\n)/", " ", $text);
  return $text;
