What about running a ngui script via lua.exe ?

I believe ngui as lua module would open new ways to use it.


Folowing is an example using wxLua. There is no message loop
there. All gui is handled in script. This program just starts it:

#include <windows.h>
extern "C"
{
    #include <lua.h>
    #include <lauxlib.h>
    #include <lualib.h>
}

//from lua.c
static int report (lua_State *L, int status) {
  if (status && !lua_isnil(L, -1)) {
    const char *msg = lua_tostring(L, -1);
    if (msg == NULL) msg = "(error object is not a string)";
    MessageBox(NULL, msg, NULL, 0); //l_message(progname, msg);
    lua_pop(L, 1);
  }
  return status;
}

int WINAPI WinMain (HINSTANCE hThisInstance,
                     HINSTANCE hPrevInstance,
                     LPSTR lpszArgument,
                     int nCmdShow)
{
    lua_State* L = lua_open();
    if (!L)
    {
        MessageBox(NULL, "Could not open Lua", NULL, 0);
        return 0;
    }
    luaL_openlibs(L);  // open std libraries
    int rc = luaL_loadfile(L, "./bbsc.lua") ||   // parse ok?
             lua_pcall(L, 0, LUA_MULTRET, 0);    // call main
    report(L, rc);
    lua_close(L);
    return rc;
}
