File

Class

RecursiveExtensionFilterCallback

Filters a RecursiveDirectoryIterator to discover extensions.

Namespace

Drupal\Core\Extension\Discovery

Code

public function accept(\RecursiveDirectoryIterator $filesystem_directory) : bool {
    $name = $filesystem_directory->getFilename();
    // FilesystemIterator::SKIP_DOTS only skips '.' and '..', but not hidden
    // directories (like '.git').
    if ($name[0] === '.') {
        return FALSE;
    }
    if ($filesystem_directory->isDir()) {
        // If this is a subdirectory of a base search path, only recurse into the
        // fixed list of expected extension type directory names. Required for
        // scanning the top-level/root directory; without this condition, we would
        // recurse into the whole filesystem tree that possibly contains other
        // files aside from Drupal.

        // contains one. However, those default configuration directories cannot
        // contain extensions. The directory name cannot be globally skipped,
        // because core happens to have a directory of an actual module that is
        // named 'config'. By explicitly testing for that case, we can skip all
        // other config directories, and at the same time, still allow the core
        // config module to be overridden/replaced in a profile/site directory
        // (whereas it must be located directly in a modules directory).
