[emacs-wiki-discuss] patch to make muse-latex2png work under XEmacs 21.4.17

[Neilen Marais]

Hi

Since no-one to my earlier mail about muse-latex2png and XEmacs 21.4.17,
I was forced to learn some elisp. Sometimes remaining silent is the best
way to teach, and for that I thank you ;P

Anyhow, the problem was that the function file-expand-wildcards is not
available in XEmacs 21.4.17. Looking at the code in question, it seems
like the return value of file-expand-wildcards isn't actually used, so
it can be safely removed without affecting behaviour.

Here is a patch to remove the call to file-expand-wildcards:

--- orig/lisp/muse-latex2png.el

-          (copy-file file (concat pubdir (file-name-nondirectory file)) t)
-          (delete-file file)
-          (concat "./latex/" (file-name-nondirectory file))))
+       (copy-file file (concat pubdir (file-name-nondirectory file)) t)
+       (delete-file file)
+       (concat "./latex/" (file-name-nondirectory file)))
     (message "The latex folder does not exist!")))
 
 (defun muse-publish-latex-tag (beg end attrs)

Thanks
