local backend

hi!

i like the idea behind your module very much but there is one thing i do not understand: why are you using an ftp and ssh backend but no local file backend? i can't imagine a case where the drupal module path is not accessible by the web server which runs drupal.

i've created a file "local.backend.inc":

// $Id$

/**
 * @file
 * The local Backend for the plugin manager.
 */

/**
 * Implementation of user hook plugin_manager_backend.  Checks
 * if the requirements for the ssh backend are enabled.
 *
 * @return
 *  Return 'local' if the requirements are available.
 */
function local_plugin_manager_backend() {
  return 'local';
}

/**
 * Install the supplied files to the appropriate locations.
 *
 * @param $files
 *   The files to install.
 * @param $type
 *   Either 'module' or 'theme' to indicate where to install to.
 * @param $username
 *   Local Username
 * @param $password
 *   Local Password
 * @return
 *  TRUE if all the files were installed, FALSE otherwise.
 */

function local_plugin_manager_copy($files, $type, $username, $password) {
  // Figure out the type of files.
  if (!in_array($type, array('modules', 'themes'))) {
    return FALSE;
  }
  $dir = 'sites/all/'. drupal_strtolower($type);

  // Prepare the directories to use later.
  $extract_dir = file_directory_path() .'/plugin_manager_extraction';


  // Try to guess the directory of the drupal install.
  // Start by putting the entire address together and replacing \ with /.
  $local_path = rtrim(str_replace('\\', '/', $_SERVER['DOCUMENT_ROOT'] . base_path()), '/');

  // Process each of the files.
  foreach ($files AS $file) {
    if (trim($file, "\\/") != $file) {
      exec("mkdir " . escapeshellarg("$local_path/$dir/$file"));
    }
    else {
      exec("cp $extract_dir/$file $local_path/$dir/$file");
    }
  }

  return TRUE;
}

other features that come to my mind:
- a quick install form where you can install a module by just pasting its url
- show which modules are already installed
(- dependency checks (i know you don't want to cover it, but it would be cool))

nice work though!
