# Lua - ESP-IDF Component ESP-IDF component which wraps Lua from upstream repository - https://www.lua.org/ This component provides Lua, a powerful, efficient, lightweight, embeddable scripting language. ## Features - Suitable for embedding Lua code inside ESP-IDF applications - Configurable stack size limit - MIT license ## Configuration option - `LUA_MAXSTACK` - default value: 1000000 - Limits the size of the Lua stack. Modify values: ```shell idf.py menuconfig ``` ## Usage This component is suitable for embedding Lua scripts in ESP-IDF applications. For a complete example, see the `examples/lua_example` directory. ### Basic Usage ```c #include "lua.h" #include "lualib.h" #include "lauxlib.h" void run_lua() { lua_State *L = luaL_newstate(); luaL_openlibs(L); // Run a simple Lua script if (luaL_dostring(L, "print('Hello from Lua!')") != LUA_OK) { printf("Error: %s\n", lua_tostring(L, -1)); } lua_close(L); } ``` ## Changes to upstream This component uses header injection to provide ESP-IDF specific configuration overrides without modifying the upstream Lua source code. The platform-specific settings (such as `LUA_32BITS` for ESP32 and Xtensa/RISC-V architectures) are defined in `lua/port/include/luaconf.h`. ## License Lua is licensed under the MIT license.
