Everyone loves Drush

Wouldn't it be cool if more modules would have a drush integration?
Here is one short introduction how to do it.

• Create a modulename.drush.inc in your modules dir
• Implement hook_drush_command:
  
  /<strong>
   * Implementation of hook_drush_command().
   */
  function mongodb_drush_command() {

    $items['mongodb-connect'] = array(
      'description' => 'A string for connecting to the mongodb.',
      // alternatives
  /</strong>
  *     DRUSH_BOOTSTRAP_DRUSH              
  *    DRUSH_BOOTSTRAP_DRUPAL_ROOT        
  *    DRUSH_BOOTSTRAP_DRUPAL_SITE        
  *    DRUSH_BOOTSTRAP_DRUPAL_CONFIGURATION
  *    DRUSH_BOOTSTRAP_DRUPAL_DATABASE    
  *    DRUSH_BOOTSTRAP_DRUPAL_FULL        
  *    DRUSH_BOOTSTRAP_DRUPAL_LOGIN        
  */
      'bootstrap' => DRUSH_BOOTSTRAP_DRUPAL_CONFIGURATION,
  //     'options' => $options,
      'arguments' => array(
         'alias' => 'The connection',
      ),
    );
    ...
    return $items;
  }

• Implement hook_drush_help
  
  /**
   * Implementation of hook_drush_help().
   */
  function mongodb_drush_help($section) {
    switch ($section) {
      case 'drush:mongodb-conf':
        return dt('Show database connection details.');
• Implement the command. The nameing convention is drush_$str_replace('-', '_', COMMAND_KEY)$, for example
  
  /**
   * Drush callback; Return the connect string.
   */
  function drush_mongodb_connect($alias = 'default') {
    $command = _drush_mongodb_connect($alias);
    drush_print($command);
  }

That's it, provide some love for your drupal module.
