| get_locale() X-Ref |
| Retrieves the current locale. If the locale is set, then it will filter the locale in the {@see 'locale'} filter hook and return the value.

Unique identifier for retrieving translated strings. param: string|false $path Optional. Path to the directory containing the .mo file. |

| translate_user_role( $name, $domain = 'default' ) X-Ref |
| Translates role name. Since the role names are in the database and not in the source there are dummy gettext calls to get them into the POT file and this function properly translates them back. The before_last_bar() call is needed, because older installations keep the roles using the old context format: 'Role name|User role' and just skipping the content after the last bar is easier than fixing them in the DB. New installations won't suffer from that problem. return: string Translated role name on success, original name on failure. since: 2.8.0 since: 5.2.0 Added the `$domain` parameter. param: string $name The role name. param: string $domain Optional.
