autoindex ($directory, sort_field => "name", fs_encoding => "utf-8")

The autoindex function takes as argument a directory and an optional named sort_field parameter for sorting, and returns a arrayref with hashrefs with the relevant file information:

        [
          {
            'location' => './../',
            'mod_time' => '08-Apr-2013 12:58',
            'name' => '..',
            'size' => '-'
          },
          {
            'location' => 'test.txt',
            'mod_time' => '08-Apr-2013 15:04',
            'name' => 'test.txt',
            'size' => '13B'
          }
        ];

You may want to specify a sort_field parameter to sort the listing (by default "name") and a file system encoding (by default "utf-8");
