我要评论c++端：
#include "stdafx.h"
lua_state *l;
void load_lua(lua_state **l,char *filename){
*l=lual_newstate();
lual_openlibs(*l);
if(lual_loadfile(*l,filename) || lua_pcall(*l,0,0,0)){
lual_error(*l,"load file error! %s",lua_tostring(*l,-1));
}
}
int _tmain(int argc, _tchar* argv[])
{
load_lua(&l,"raw.lua"); //此处若直接传入l会出错
lua_getglobal(l,"gettable");
if(lua_pcall(l,0,1,0) !=0){
lual_error(l,"pcall wrong %s",lua_tostring(l,-1));
}
lual_checktype(l,1,lua_ttable);
int n=lua_objlen(l,1);
printf("n = %d\n",n);
lua_pushstring(l,"ee");
lua_rawseti(l,1,5); //t[n]=v,n为第三个参数，v是栈顶元素
n=lua_objlen(l,1);
printf("n = %d\n",n);
int i;
for(i=1;i<=n;i++){
lua_rawgeti(l,1,i);
printf("%s\n",lua_tostring(l,-1));
}
return 0;
}
lua脚本：
function gettable()
tb={ "aa","bb","cc","dd"}
return tb
end
运行输出的结果为：
n = 4 n = 5 aa bb cc dd ee
