Lua语言学习(一)

Lua语言：轻量脚本语言，多作为功能扩展使用，标准C语言编写，可扩展性高，支持面向过程编程和面向函数编程。本文主要是环境安装，简单的两种编程方式，如何注释

Lua环境安装

Linux查看机器Lua环境版本

[moic@localhost lua_learn]$ lua -v

环境安装

[moic@localhost lua_learn]$ curl -R -O http://www.lua.org/ftp/lua-5.3.0.tar.gz

[moic@localhost lua_learn]$ ls
lua-5.3.0.tar.gz
[moic@localhost lua_leanrn]$ tar -zxvf lua-5.3.0.tar.gz
[moic@localhost lua_leanrn]$ cd lua-5.3.0
[moic@localhost lua_leanrn]$ make linux test
[moic@localhost lua_leanrn]$ make install

脚本式编程

[moic@localhost lua_leanrn]$ vi HelloWorld.lua
[moic@localhost lua_leanrn]$ lua HelloWorld.lua
hello world~

HelloWorld.lua

print("hello world~")

交互式编程

[moic@localhost lua_leanrn]$ lua -i
> print("test lua")
test lua
>

注释

单行注释
