《Lua程序设计》学习笔记
命令行执行类型为table的全局变量arg保存命令行参数，脚本名为arg[0]，真正的参数从arg[1]开始，而脚本之前则是负数的下标
例如lua -e "sin=math.sin" script a b的参数如下
arg[-3] = "lua"arg[-2] = "-e"arg[-1] = "sin=math.sin"arg[0] = "script"arg[1] = "a"arg[2] = "b"
八种基本数据类型
nil
Boolean
number
string
userdata
function
thread
table
Lua是一个动态类型语言，不用声明变量的类型，每个变量携带自己的类型
type(v) 获取v的变量类型，返回的是字符串
type(a) --> nila = 1 type(a) --> numbera = "1" type(a) --> ...
