drupal\features : Delete all menu links before reverting a feature

main_menu.module

/**
 * Implements hook_pre_features_revert().
 *
 * If a menu link is added in a menu handled by this feature, it won't be deleted when the menu feature is reverted.
 * Only the menu links exported in the feature will be reverted.
 * Implementing this hook allows us to make sure that the menu is fully resetted after the revert
 * by first deleting all menu links before reverting.
 */
function main_menu_pre_features_revert($component) {
  if($component == 'menu_links') {
    // Delete all menu links before reverting
    menu_delete_links('main-menu');·
  }
}
