What is the replacement of drupal_match_path() in Drupal 8? The following function is removed from Drupal 8. How can I achieve same functionality in Drupal 8?

function drupal_match_path($path, $patterns) {
  $regexps = &drupal_static(__FUNCTION__);

  if (!isset($regexps[$patterns])) {
    // Convert path settings to a regular expression.
    // Therefore replace newlines with a logical or, /* with asterisks and the <front> with the frontpage.
    $to_replace = array(
      '/(\r\n?|\n)/', // newlines
      '/\\\\\*/', // asterisks
      '/(^|\|)\\\\<front\\\\>($|\|)/', // <front>
    $replacements = array(
      '\1' . preg_quote(config('system.site')->get('page.front'), '/') . '\2',
    $patterns_quoted = preg_quote($patterns, '/');
    $regexps[$patterns] = '/^(' . preg_replace($to_replace, $replacements, $patterns_quoted) . ')$/';
  return (bool) preg_match($regexps[$patterns], $path);

New PathMatcher service reports that the path.matcher service was introduced to deprecate most procedural functions in the path.inc file with its methods.
In particular, the equivalent of $path_matches = drupal_match_path($path, $patterns); is the following code.

$path_matches = \Drupal::service('path.matcher')->matchPath($path, $patterns);

The same service is used to check if the currently viewed page is the front page.

$is_front = \Drupal::service('path.matcher')->isFrontPage();

As usual, injecting the dependency is preferred over calling \Drupal::service().

  • Is there any need to include '@path.matcher' service in mymodule.service.yml? Sep 16, 2016 at 6:00
  • If you have a service that depends on path.matcher, you can declare it as dependency. Then the question would be "Do I need to create a service?" That depends from the code you are writing. Notice also that, if you have a form, you can inject its dependencies too.

  • How can I inject this dependency ? Sep 16, 2016 at 6:10
  • It depends from the code you are using. That is a different question, though.

  • For database operations I used '@database' as argument in service.yml. Can I inject this service as well?I have a simple form with CRUD operations. Sep 16, 2016 at 6:12
