如何让 quicklisp 加载 Practical Common Lisp 一书中的代码?

How do I get quicklisp to load code from the book Practical Common Lisp?

code that accompanies the book Practical Common Lisp includes asdf files. How do I use Quicklisp要加载这段代码吗?

  1. http://www.gigamonkeys.com/book/practicals-1.0.3.tar.gz的内容复制到~/quicklisp/local-projects/
  2. 在 REPL
  3. 调用 (ql:register-local-projects)
  4. 从所需章节加载代码(仅测试第 25 章)

CL-USER> (ql:quickload "id3v2")
To load "id3v2":
  Load 1 ASDF system:
    id3v2
; Loading "id3v2"
[package com.gigamonkeys.macro-utilities].........
[package com.gigamonkeys.binary-data].............
[package com.gigamonkeys.pathnames]...............
[package com.gigamonkeys.id3v2]...............
("id3v2")
CL-USER> (in-package "COM.GIGAMONKEYS.ID3V2")
