:::info[Note] This is a point-in-time snapshot of the API documentation from January 2026. Going forward, we will not be maintaining a public copy of these references, and recommend users to refer to the built-in signature helpers available in the Hack LSP instead for complete and up-to-date information. :::
Retrieve the locale being used by libc functions for the current thread
namespace HH\Lib\Locale;
function get_native(): Locale;
In general, we discourage this: it can be surprising that it changes the
behavior of many libc functions, like sprintf('%f'), and error messages
from native code may be translated.
For web applications, that's likely unwanted - we recommend frameworks add the concept of a 'viewer locale', and explicitly pass it to the relevant string functions instead.
