Escaping spaces when calling (buffer-file-name) in emacs

So, I had a question about getting word count to work properly in emacs LaTeX mode (auctex, actually, but never mind.) That was answered fine. Then I found I had trouble when the (buffer-file-name) included spaces. This made it mess up. This problem was got around too. Now the problem is that the solution breaks when there AREN'T any spaces.

So currently I have two emacs commands:

(defun latex-word-count ()
  (interactive)
  (shell-command (c开发者_高级运维oncat "/usr/local/bin/texcount.pl "
                         "-inc "
                     (shell-quote-argument (concat "'" (buffer-file-name) "'")))))

this works when there is a space in the containing folder.

(defun latex-word-c-nospace ()
  (interactive)
  (shell-command (concat "/usr/local/bin/texcount.pl "
             "-inc "
             (shell-quote-argument (buffer-file-name)))))

This works when there is no space in the containing folder name. (OK so the indenting is a little screwey, but whatever)

My question: is there some way to have the same function work in both cases? This answer suggests the problem is with texcount rather than emacs. Is there a way to do this without messing about with texcount.pl? Or is my best bet to poke texcount.pl in the way Chris Johnsen suggested on SU?

Your second routine should work whether there are spaces in the file name or not. For example, I created this little command:

(defun ls-l ()
  (interactive)
  (shell-command (concat "ls -l "
                         (shell-quote-argument
                          (buffer-file-name)))))

It works when I invoke it while editing a file called foo.txt and when editing a file called foo bar.txt.

You always have the option of having emacs determine if the file name has a space:

(defun latex-word-count ()
  (interactive)
  (let* ((has-space (string-match " " buffer-file-name))
         (quoted-name (shell-quote-argument
                       (if has-space
                           (concat "'" buffer-file-name "'")
                         buffer-file-name))))
    (shell-command (concat "/usr/local/bin/texcount.pl "
                           "-inc "
                           quoted-name))))

I'm the developer of TeXcount and came across this posting just a little while ago.

As is pointed out, the problem is with TeXcount, so the best solution is to fix TeXcount rather than hack some other solution. I have an update available on the TeXcount web page in which I hope the problem is solved: http://folk.uio.no/einarro/TeXcount/download.html

NB: This is the temporary version of the new web pages, and may move later on if I decide to new address for TeXcount.

The problem came about because, in order to allow wildcards in file names under Windows, I had used <@files> to get all the files, and this didn't like the spaces. In Linux, you could just use @files without the glob (<...>), but I'd like TeXcount to work in Windows too, so a better solution was to escape the spaces before passing them to the glob.

Hope this helps, and if it doesn't please contact me and I'll see if I can help...I'm not a regular here, so I might not notice questions if posted as replies.
