["Karsten Schulz" <kahnpost@...>]

is that what u like ?

 

int CLuaCallBacks::_print(lua_State *lua)//DirectCallFunction
{
lua_pushlightuserdata(lua, pid);
lua_gettable(lua, LUA_REGISTRYINDEX);
CLuaScript *pThis = (CLuaScript *)lua_touserdata(lua, -1);

if(!pThis) return 0;
int n = lua_gettop(lua); //number of arguments
for (int i = 1; i < n; i++)
{
pThis->Print("%s\r\n",lua_tostring(lua, i));
}
return 0;
}

Subject: Lua 5.1f: How to dump stack contents from C?

I'm using Lua 5.1 final, and I need a stack dump function.  What I came up with doesn't seem to print accurately, or anything at all.  Does anyone know how I might change this to make it work ? It's very difficult for me to work if I cannot see my Lua error messages:


static void stackDump (lua_State *L) {
      int i=lua_gettop(L);
      printf(" ----------------  Stack Dump ----------------" );
      while(  i   ) {
        int t = lua_type(L, i);
        switch (t) {
          case LUA_TSTRING:
            printf("%d:`%s'", i, lua_tostring(L, i));
          break;
          case LUA_TBOOLEAN:
            printf("%d: %s",i,lua_toboolean(L, i) ? "true" : "false");
          break;
          case LUA_TNUMBER:
            printf("%d: %g",  i, lua_tonumber(L, i));
         break;
         default: printf("%d: %s", i, lua_typename(L, t)); break;
        }
       i--;
      }
     printf("--------------- Stack Dump Finished ---------------" );
}
