Hello, Indeed the "proper" way of including a script would be to store it in a file system.
However, when I needed to include a single and small script and I didn't want to introduce a complete FS just for this, I used xxd. xxd can convert any file to a C header file. You can then include the header, and access the whole file as a variable. Here is an example: I added this in my app Makefile: # Setup any special pre-build context context: header $(Q) cd path/to/libs/json.lua/ && xxd -i json.lua > json_lua.h && echo -n "const " | cat - json_lua.h > temp && mv temp json_lua.h And then I used the file like this: #include "lua.h"#include "lauxlib.h"#include <string.h> #include "json_lua.h" static int luaopen_json(lua_State * L); void ExtLibs_load(lua_State * L){ // json.lua#ifdef CONFIG_EXT_LIB_JSON_LUA luaL_requiref(L, "json", luaopen_json, 1); lua_pop(L, 1);#endif} int luaopen_json(lua_State * L){ const char * modname = lua_tostring(L, 1); if (strcmp(modname, "json") != 0) return luaL_error(L, "cannot load json module"); if (luaL_loadbufferx(L, (char*)json_lua, json_lua_len, "json", "t") != LUA_OK) return lua_error(L); lua_call(L, 0, 1); return 1;} I hope this helps...
