[cl-ppcre-devel] Problem with pathnames

[Juan Jose Garcia-Ripoll]

I reported a related problem some time ago

   http://lists.common-lisp.net/pipermail/cl-ppcre-devel/2011-January/000706.html

However, instead of the values I supplied now cl-unicode is using :unspecific for the :type of a pathname.

(defun dump-derived-tests ()

  "Parses the Unicode data file \"DerivedCoreProperties.txt\" \(which

is not used in read.lisp) and uses it to create a file

\"derived-properties\" which will be used by CL-UNICODE-TEST."

  (with-output-to-source-file (out (make-pathname :name "derived-properties"

                                                  :type :unspecific

                                                  :directory '(:relative :up "test"))

                                   :no-header-p t)

This is not supported by ECL, which uses NIL to represent an unfilled value (absent therefore). From the Hyperspec

http://www.lispworks.com/documentation/HyperSpec/Body/19_bbbc.htm

A conforming program must never unconditionally use a :unspecific as the value of a pathname component because such a value is not guaranteed to be permissible in all implementations.

Probably what you want to solve is the merge-pathnames above the code (in the macro), which might instead read

  `(let* ((directory (make-pathname :name nil :type nil :version nil :defaults *this-file*))

          (pathname (merge-pathnames ,relative-path directory))

Cheers,

Juanjo

Hi Juanjo,

Thanks for the heads-up. Can you send a diff against the BKNR
repository? I'll review and apply it.

Thanks,
Edi.

I am sorry, I live behind a firewall and unblocking SVN is quite a hassle. Is it ok with the patch attached? It is against cl-unicode-0.1.1

That should do, thanks. I'll take care of it in the next days.

I was going to apply your patch this morning, but I just realized this
had already been done eight months ago... :)

Hmm, then why didn't this propagate to quicklisp's release? I bet they try to keep on the edge of various libraries and eight months is a long time.
