概要

我试图成为使用Lisp的能力。虽然我很舒服命令行和其他口译员的各种REPL（即python， irb / pry, perl -d），当它到来时，我一直觉得自己像个绝对的新手 Lisp，出于某种原因。

在Common Lisp REPL（clisp）中，当我在a的末尾使用密钥时功能名称，似乎是试图为我提供参考信息关于那个功能。这听起来很有用..如果真的有用的话。下面是我这样做时实际发生的事情。据我所知，它似乎是查找不存在（或不再存在）的URL上的函数。也许 HyperSpec移动了吗？解决这个问题的正确方法是什么？我该怎么办？

我认为this article可以帮到你。

实质上，您必须设置CUSTOM:*BROWSERS*列表，因此clisp知道如何打开文档。

在.clisprc.lisp

中

(setf CUSTOM:*BROWSERS* '(
   (:CHROMIUM "/usr/bin/chromium" "~a")))
(setf CUSTOM:*BROWSER* :CHROMIUM)
(setf CUSTOM:CLHS-ROOT "http://www.ai.mit.edu/projects/iiip/doc/CommonLISP/HyperSpec/FrontMatter/")

但是你必须在你的系统上安装chrome。但是你明白了。

如何在Common Lisp REPL中修复<tab> -triggered自动文档查找的URL？
