Hey,
This is probably a rather stupid question.
Either way, I use the texcount.pl script to count words in LaTeX document.
The output is something like this:
FILE: hist_pol_oko.tex
Words in text: 3811
Words in headers: 43
Words in float captions: 0
Number of headers: 7
Number of floats: 0
Number of math inlines: 0
Number of math displayed: 0
I have added the following to my .emacs file
(add-to-list 'TeX-command-list
(list "Count Words" "texcount.pl %s.tex"
'TeX-run-command nil t)
)
First, when I have Count Words from within AUCTeX the status line displays
"Count Words: Done". Instead, I would like it to display the number of
words. In the example above it would be "3811 words".
Second, would also be nice, if Emacs would be able to do a calculation.
I.e. "3811 words and 10.88 normal page(s)". The second figure would be
calculated by dividing 3811 with 350.
Third, I would be nice if I could define a alias for the "Count Words"
command. I.e. "Wordcount" and "Count Words" would run the same script. I
was only able to find
(defalias 'perl-mode 'cperl-mode)
in the "Learning GNU Emacs", and as far as I can tell it would not work
with this kind of command.
I am sorry for asking so many questions, but I am really unfamiliar with
Lisp.
Thanks a bunch,
Rasmus

emacs lisp has a function to call a unix command line and receive its
output. For a example, see: the xGetDimention at
Elisp Lesson: Writing image-linkify Function
http://xahlee.org/emacs/elisp_image_tag.html
So, you can call your perl and gets its output. Then, it's easy to
extract word count from there. To extract, you'll need to:
1. create a temp buffer.
2. insert the output there. (so that you have a buffer to work with,
much more easier than processing a big string)
3. use search-forward-regex or get the word count, put it to a
variable.
4. kill the temp buffer.
5. Now you can print your count, or do more computation.
Heres a sample of opening a temp buffer
; a elisp idiom for processing a file without user interaction
(save-current-buffer
(set-buffer (get-buffer-create " myTemp"))
(insert-file-contents filePath nil nil nil t)
; process it ...
)

「Third, I would be nice if I could define a alias for the "Count
Words" command. I.e. "Wordcount" and "Count Words" would run the same
script.」
emacs's symbols normally don't spaces. You might try with "\ " or
quote the whole thing. Possibly there's a workaround so you can have
command names with spaces, but best just not to do it.
