LISP MAKE-PATHNAME:非法:DIRECTORY论点

标签: lisp common-lisp clisp pathname

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

并跟着它读了我, 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错误或如何解决它以使项目运行?

答案 0 :(得分:4)

snp-loader.lisp 中,您需要致电directory-namestring而不是pathname-directory

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

但是,在为expectations-on-token定义方法时,稍后会出现另一个问题。在 c-snp-with-vars.lisp 中,文档字符串格式错误,从而触发错误。加入两个字符串:

(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。
