Run Lua code block inside C++

Question

How do I run a Lua code block inside a C function++?

The idea would be something like:

int main() {
  tipodavariavel script;
  script << "print('Ola mundo')";
  executar(script);
  return 0;
}

Answer 1

This is an example of basic code to run a script Lua. Note that essentially C syntax is used:

extern "C" {
#include "lua.h"
#include "lualib.h"
#include "lauxlib.h"
}
 
int main() {
    lua_State *L = lua_open();
    luaL_openlibs(L);
    luaL_dostring(L, "print('Ola mundo')");
    lua_close(L);
}

I put in the Github for future reference.

To compile you must use something like this using GCC/Mingw:

g++ -o interpetadorlua.cpp -llua -ldl

Generally speaking this is, I don’t know if you need anything specific.
