mac osx 下安装lisp环境sbcl,并解决方向键不能用问题

首先假设你的系统已经安装好homebrew, 若没有安装可参看我之前的博客: mac osx 下的apt-get，yum的代替工具 －－－－homebrew

安装sbcl

$brew install sbcl

sbcl交互模式下, 输入代码时不支持左右箭头移动光标,比较崩溃.
如下图

$ sbcl
This is SBCL 1.3.14, an implementation of ANSI Common Lisp.

接下来安装rlwrap

$ brew install rlwrap

rlwrap是命令行输入交互增强工具, 可以解决左右方向键问题和支持历史命令等. 使用以下命令启动sbcl即可

$ rlwrap sbcl
