Lua Interacting with C

在C中启动Lua

启动一个Lua State并处理输入:


#include <stdio.h>
#include <string.h>
#include "lua.h" //Lua头文件
#include "luaxlib.h" //Lua辅助库
#include "lualib.h" //Lua自带的库
int main(void) {
  char buff[256];
  int error;
  lua_State *L = luaL_newstate(); //初始化Lua State
  luaL_openlibs(L); //加载Lua自带的lib库
  while (fgets(buff, sizeof(buff), stdin) != NULL) {
    error = luaL_loadstring(L, buff) || lua_pcall(L, 0, 0, 0);
    if (error) {
      fprintf(stderr, "%s\n", luaL_tostring(L, -1);
      lua_pop(L, 1);
    }
  }
  lua_close(L):
  return 0;
}
