C-c C-c for a file extension

[Rares Vernica]

Hi,

How can I define a C-c C-c command for a certain file extension.

For example, I have the gnuplot (.plt) file and I would like to run 
"gnuplot %f" (where %f is the file name) when I press C-c C-c on that file.

Thanks a lot,
Ray

Usuallly a file extension is associated with a major mode (via
auto-mode-alist).  What does `C-h v major-mode' tell you when visiting
such a file?

Hmmm, when I visit a .plt file it's in Fundamental mode.  You could
define your own Gnuplot mode (with a local keymap that binds `C-c C-c'
to an Emacs command that runs gnuplot on the visited file) and associate
it with the .plt extension (e.g. with define-generic-mode), but it'd be
a lot easier to use `M-x compile' in conjunction with this:

(defun set-gnuplot-compile-command ()
   (set (make-local-variable 'compile-command)
        (format "gnuplot %s" (file-name-nondirectory buffer-file-name))))

(add-hook 'find-file-hook 'set-gnuplot-compile-command)
(add-hook 'find-file-not-found-hooks 'set-gnuplot-compile-command)

The answer would be slightly different if your gnuplot files have a
major mode (do they?), but for now, you can just do

M-: (local-set-key "\C-c\C-c" 'compile)

And then C-c C-c will run the compile command.  The first time you call
compile, it will start with "make -k" but you can change that to
gnuplot <filename>

If you're really lazy, you could do something like this:

(defun compile-gnuplot (filename)
  "Runs gnuplot on FILENAME taking (buffer-file-name) as default."
  (interactive (let ((name (buffer-file-name)))
                 (list (read-string (format "Filename (default %s) "
name)
                                  nil
                                  name))))
  (compile (format "gnuplot %s" filename)))

Then, in your buffer,
M-: (local-set-key "\C-c\C-c" 'compile-gnuplot)

I'm new to emacs lisp so comments on code also requested.  Ideally, the
function should also ask to save the buffer if it is modified.  But I
don't know elisp that well.

Hope this helps.

A long time ago, someone in the Lisp industry told me it was poor form
quote people; it suggests that they lack value.

gnuplot comes with a gnuplot mode in gnuplot.el (and gnuplot-gui.el).

gnuplot.el has `C-c C-b' for `gnuplot-send-buffer-to-gnuplot'.  It
would be better if they'd bind `gnuplot-send-buffer-to-gnuplot' or
`gnuplot-send-file-to-gnuplot' instead of
`gnuplot-gui-set-options-and-insert' to `C-c C-c'.

Bye, Reiner.

I installed gnuplot-module and everything works great.

Thanks a lot,
