✏️ Editing: _lua_builtins.py

"""
    pygments.lexers._lua_builtins
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This file contains the names and modules of lua functions
    It is able to re-generate itself, but for adding new functions you
    probably have to add some callbacks (see function module_callbacks).

Do not edit the MODULES dict by hand.

Run with `python -I` to regenerate.
