本文介绍了交互式lua：命令行参数的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想做
lua prog.lua arg1 arg2
在prog.lua里面，我想说，例如
Inside prog.lua, I want to say, for instance
print (arg1, arg2, '\n')
Lua似乎没有argv [1]等等，我看到的处理命令行参数的方法似乎不成熟和/或繁琐。我缺少什么？
Lua doesn't seem to have argv[1] etc and the methods I've seen for dealing with command line arguments seem to be immature and / or cumbersome. Am I missing something?
推荐答案
您缺少了 arg 你想在 arg [1] ， arg [2] ，等等：
You're missing the arg vector, which has the elements you want in arg[1], arg[2], and so on:
% lua -i -- /dev/null one two three

> print(arg[2])
