How can I get the human name from the machine name for an extension?

Question

I want to get the human name from the machine name for an extension (i.e. a module or a theme).

I know that I can do this for a module by this call:

$human_name = \Drupal::service('extension.list.module')->getName('automated_cron');

This will return the human name for core Automated Cron module.

To do the same thing for a theme, I can invoke the service 'extension.list.theme'.

Is there something that will provide this information and not care whether the extension is a module or a theme?

In my current implementation, I use this workaround:

$extension_name = 'automated_cron';
if (\Drupal::service('module_handler')->moduleExists($extension_name)) {
  $human_name = \Drupal::service('extension.list.module')->getName($extension_name);
}
else {
  $human_name = \Drupal::service('extension.list.theme')->getName($extension_name);
}
dpm($hunan_name, 'human name');

Is there a simpler way to get the desired result (i.e. without using an if-test)?

Answer 1

Both extension.list.module and extension.list.theme services extends ExtensionList to get human name.

So you can replace your if statement by this one :

$name = 'automated_cron';
$extension = \Drupal::service('extension.list.module');
$human_name = ($extension->exists($name)) ? $extension->getName($name) : '';
