function scald_plugin_display_library::execute in Scald: Media Management made easy 6

Same name and namespace in other branches

The library won't go through the normal theming / page rendering process. Instead, we'll just fetch / render the atoms, and print the JSON by itself. We won't be returning anything, which tells Drupal that everything is already rendered.
