Functions to handle paths in Backdrop, including URL aliasing.

Code

function backdrop_get_normal_path($path, $langcode = NULL) {
  $original_path = $path;

  // Lookup the URL alias first.
  if ($source = backdrop_lookup_path('source', $path, $langcode)) {
    $path = $source;
  }

  // Allow other modules to alter the inbound URL. We cannot use backdrop_alter()
  // here because we need to run hook_url_inbound_alter() in the reverse order
  // of hook_url_outbound_alter().
  foreach (array_reverse(module_implements('url_inbound_alter')) as $module) {
    $function = $module . '_url_inbound_alter';
