LISP MAKE

LISP MAKE-PATHNAME：非法：DIRECTORY论点(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

并按照它读给我，通过使用CLISP解释器我将目录更改为该文件夹，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什么是错的，或者我如何修复它以使项目运行？

I download Semantic Network Processor project: http://digital.cs.usu.edu/~vkulyukin/vkweb/software/snp/snp.html

and following it's read me, By using CLISP interpreter I change the directory to the folder, and do the following:

[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

can anybody tells me what's wrong or how I can fix it in order to make the project run?

最满意答案

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

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

但是，在为expectations-on-token定义方法时，后来会出现另一个问题。 在c-snp-with-vars.lisp中 ，docstring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。

编辑。 我联系了原作者; 最新版本的代码现在托管在GitHub上， 网址为https://github.com/VKEDCO/AI/tree/master/NL/SNP 。

In snp-loader.lisp, instead of directory-namestring, you need to call pathname-directory:

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

But then another problem occurs later, when defining a method for expectations-on-token. In c-snp-with-vars.lisp, the docstring is malformed, which triggers an error. Join both strings:

(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)))

Reload the snp-loader.lisp file, and retry (snp-load-everything). It should load properly.

Edit. I contacted the original author; the latest version of the code is now hosted on GitHub at https://github.com/VKEDCO/AI/tree/master/NL/SNP.
