/**
 * lite_xl_plugin_api.h
 * API for writing C extension modules loaded by Lite XL.
 * This file is licensed under MIT.
 * 
 * The Lite XL plugin API is quite simple.
 * You would write a lua C extension and replace any references to lua.h, lauxlib.h
 * and lualib.h with lite_xl_plugin_api.h.
 * In your main file (where your entrypoint resides), define LITE_XL_PLUGIN_ENTRYPOINT.
 * If you have multiple entrypoints, define LITE_XL_PLUGIN_ENTRYPOINT in one of them.
 * 
 * After that, you need to create a Lite XL entrypoint, which is formatted as
 * luaopen_lite_xl_xxxxx instead of luaopen_xxxxx.
 * This entrypoint accepts a lua_State and an extra parameter of type void *.
 * In this entrypoint, call lite_xl_plugin_init() with the extra parameter.
 * If you have multiple entrypoints, you must call lite_xl_plugin_init() in
 * each of them.
 * This function is not thread safe, so don't try to do anything stupid.
 * 
 * An example:
 * 
 * #define LITE_XL_PLUGIN_ENTRYPOINT
 * #include "lite_xl_plugin_api.h"
 * int luaopen_lite_xl_xxxxx(lua_State* L, void* XL) {
 *   lite_xl_plugin_init(XL);
 *   ...
 *   return 1;
 * }
 * 
 * You can compile the library just like any Lua library without linking to Lua.
 * An example command would be: gcc -shared -o xxxxx.so xxxxx.c
 * You must not link to ANY lua library to avoid symbol collision.
 * 
 * This file contains stock configuration for a typical installation of Lua 5.4.6.
 * DO NOT MODIFY ANYTHING. MODIFYING STUFFS IN HERE WILL BREAK
 * COMPATIBILITY WITH LITE XL AND CAUSE UNDEBUGGABLE BUGS.
 * 
 * For reference, here are a list of permalinks to previous version of this file that targets an older version of Lua.
 * If you don't need functionalities offered by the new version, use the OLDEST FILE for backwards compatibility.
 * 
 * - Lua 5.4.4: https://github.com/lite-xl/lite-xl/blob/397973067f14420b26e3b20a238a50016c0b75e2/resources/include/lite_xl_plugin_api.h
