Globals

Eryx introduces a small number of globals into the Luau environment.

_DIR

This global is a string representing the directory where the current script is located.

Note that current script here refers to the script containing the reference to _DIR, not the current working directory or the script used as the program's entrypoint.

In non-script environments, such as the REPL, this value is nil.

_FILE

This global is a string representing the complete path for the current script.

In non-script environments, such as the REPL, this value is nil.

_RUNTIME

This global identifies the current runtime (Eryx) and its configuration. It follows the _RUNTIME specification.

_LUAU

This global identifies the current Luau version and its configuration. It follows the _RUNTIME specification.

u and unicode

These two globals introduce native unicode strings into Luau. Documentation is provided in the unicode documentation.
