Question

我想从REPL或shell中读取clisp函数的帮助。我找到了（符号 - plist）函数，它给出了这个：

(symbol-plist 'bit)
(SYSTEM::TYPE-SYMBOL #<COMPILED-FUNCTION SYSTEM::TYPE-SYMBOL-BIT>
 SYSTEM::SETF-EXPANDER SYSTEM::STORE SYSTEM::DOC
 (CLHS "Body/any_bit.html" SYSTEM::FILE
  ((DEFSETF #P"/build/buildd/clisp-2.49/debian/build/places.fas" 941 941))))

但为了理解（位）是如何工作的，它不是那么有用的信息？

那么clisp函数的任何手册和文档都有类似man in shell的内容吗？

Answer 2

在这里，这可能是有意义的。以下是简短摘录：

[功能]位位阵列＆amp; rest下标sbit simple-bit-array＆amp; rest   标

bit与aref完全相同，但需要一个位数组，即一个   类型（数组位）。结果将始终为0或1.sbit就像   但另外要求第一个参数是简单的   数组（见2.5节）。注意bit和sbit，不像char和   schar，允许第一个参数成为任何等级的数组。

此外，this是指向clisp手册相应部分的链接的巨大索引。
