Reader Macros in Common Lisp

Reader Macros in Common Lisp

This post also appears on lisper.in.

Reader macros are perhaps not as famous as ordinary macros. While macros are a great way to create your own DSL, reader macros provide even greater flexibility by allowing you to create entirely new syntax on top of Lisp.

Paul Graham explains them very well in [On Lisp][] (Chapter 17, Read-Macros):

The three big moments in a Lisp expression's life are read-time, compile-time, and runtime. Functions are in control at runtime. Macros give us a chance to perform transformations on programs at compile-time. ...read-macros... do their work at read-time.

解决 OSX 上原生 VPN (Cisco IPSec)每隔一小时要求输入密码的情况

解决方案来自:[Apple Support Communities] (https://discussions.apple.com/thread/3275811?start=0&tstart=0)

  1. 连接 VPN Cisco IPSec (让系统生成配置文件)
  2. 拷贝配置文件到/etc/racoon打开终端执行:
    $ sudo cp /var/run/racoon/xxx.xxx.xxx.xxx.conf /etc/racoon
  3. 修改 racoon 配置文件:
    $ sudo vim /etc/racoon/racoon.conf
  4. 将最后一行注释掉（目的是不使用系统生成配置）:
    # include "/var/run/racoon/*.conf" ;
  5. 将下面一行添加到文件末尾，包含分号（使用定制的配置文件）:
