LISP MAKE-PATHNAME:非法:DIRECTORY 参数

LISP MAKE-PATHNAME: Illegal :DIRECTORY argument

我下载语义网络处理器项目: http://digital.cs.usu.edu/~vkulyukin/vkweb/software/snp/snp.html

接着是读我, 通过使用 CLISP 解释器,我将目录更改为文件夹, 并执行以下操作:

[3]> (load "snp-loader.lisp")
;; Loading file snp-loader.lisp ...
;; Loaded file snp-loader.lisp
T

[4]> (in-package "USER")

<PACKAGE COMMON-LISP-USER>

[5]> (snp-load-everything)

**- MAKE-PATHNAME: Illegal :DIRECTORY argument "D:\snp-stable\"**

The following restarts are available:
ABORT          :R1      Abort main loop

任何人都可以告诉我哪里出了问题或者我该如何解决它才能完成项目 运行?

snp-loader.lisp中,而不是directory-namestring,你需要调用pathname-directory:

(defparameter parm-snp-load-dir 
  (pathname-directory *load-truename*))

但随后在为 expectations-on-token 定义方法时出现了另一个问题。在 c-snp-with-vars.lisp 中,docstring 格式错误,从而触发错误。连接两个字符串:

(defmethod expectations-on-token ((this-snp c-snp-with-vars) (tok t))
  "Overloaded expectations-on-token to process variables and tests.
Get all expectations waiting for the token tok."
  `(,@(find-static-expectations this-snp tok)
       ,@(find-dynamic-expectations this-snp tok)))

重新加载 snp-loader.lisp 文件,然后重试 (snp-load-everything)。它应该正确加载。
