Is it possible to get a list of all the javascript files in the libraries directory? So far I have tried using files_scan directory but it's not returning anything:

$dir = base_path() . 'sites/all/libraries/';
$files = file_scan_directory($dir, "/.*\.js$/");
dpm($files);

many thanks.

EDIT

I changed to using DRUPAL_ROOT. This gives the correct path and returns an array of js files but there is a double slash // in the uri just before the file names: /var/www/html/droop/sites/all/libraries//d3/d3.min.js

$dir = DRUPAL_ROOT . '/sites/all/libraries/';
$files = file_scan_directory($dir, "/.*\.js$/");
dpm($files);
  • out of interest, why do you need to do this? – autopoietic Dec 15 '14 at 16:28
  • a module with a field that to allows admin to pick from a set of js files to load with an HTML5 canvas element on each blog post. – RobotEyes Dec 15 '14 at 16:38
  • that is because you have a slash after the path you are searching for ('/sites/all/libraries**/**'). just remove the trailing slash there – autopoietic Dec 15 '14 at 17:06

libraries_get_libraries should return an array of library directories, with the library name as the key and the directory as the value.

libraries_get_path will get you the path to a specific library (js).

Follwing your approach, this works fine for me:

  $dir = "sites/all/libraries";
  $files = file_scan_directory($dir, '/.*\.js$/');

I think it might be base_path that is breaking it in your example, as it adds a / in front of the (relative) path from the site root.

Combining libraries_get_libraries with file_scan_directory will also get you libraries from profile and site specific directories:

$libraries_array = libraries_get_libraries();
foreach($libraries_array as $library => $directory) {
  $files = file_scan_directory($directory, '/.*\.js$/');
  $js_paths[$library] = $files;
}
dpm($js_paths);

It may be worth noting that these libraries may contain many javascript files that are not actually used by modules.

I am looking into it a little more but for starters does dpm() show the correct value for $dir? Also, according to the documentation the trailing slash on $dir is not supposed to be there.

code that is working for me:

$dir = DRUPAL_ROOT . '/sites/all/libraries';
$files = file_scan_directory($dir, '/.*\.js/');
dpm($files);

  • Using DRUPAL_ROOT instead of base_path() fixes the path but there is a double slash in the file uri now (see my edit) thanks – RobotEyes Dec 15 '14 at 16:58
  • Is there a trailing slash on $dir? – sareed Dec 15 '14 at 17:06
  • ah yes. It works with DRUPAL_ROOT if I take off the trailing slash and add a leading slash. $dir = DRUPAL_ROOT . '/sites/all/libraries'; – RobotEyes Dec 15 '14 at 17:11
