R scratch buffer

R scratch buffer

[Benoit G.]

Dear all,

I am trying to make a second scratch buffer which enable automatically the R-mode.
I copy-paste-modified a code I found on the www but this don't seems to work (the buffer is created but in fundmental mode).

Can you help me solving this issue?

Here is a part of my .emacs file :

   (save-excursion
      (set-buffer (get-buffer-create "*scratch-R*"))
      (R-mode)
      (make-local-variable 'kill-buffer-query-functions)
      (add-hook 'kill-buffer-query-functions 'kill-scratch-R-buffer))

    (defun kill-scratch-R-buffer ()
      ;; The next line is just in case someone calls this manually
      (set-buffer (get-buffer-create "*scratch-R*"))
      ;; Kill the current (*scratch-R*) buffer
      (remove-hook 'kill-buffer-query-functions 'kill-scratch-R-buffer)
      (kill-buffer (current-buffer))
      ;; Make a brand new *scratch-R* buffer
      (set-buffer (get-buffer-create "*scratch-R*"))
      (R-mode)
      (make-local-variable 'kill-buffer-query-functions)
      (add-hook 'kill-buffer-query-functions 'kill-scratch-R-buffer)
      ;; Since we killed it, don't let caller do that.
      nil)

I'd rather do something like this:

    (defun r-scratch ()
      "Create and/or switch to the *R-scratch* buffer."
      (interactive)
      (switch-to-buffer (get-buffer-create "*R-scratch*"))
      (R-mode)
      (add-hook 'kill-buffer-query-functions 'kill-scratch-R-buffer))


    (defun kill-scratch-R-buffer ()
       "If the current buffer is the *R-scratch* buffer, then  kill it
     and recreate a virgin *R-scratch* buffer."
       (when (eq (get-buffer "*R-scratch*") (current-buffer))
         (kill-buffer (current-buffer))
         (r-scratch))
      nil)

Thank you for answering.

I still have a problem with this function.
Indeed, while calling r-scratch in my .emacs, this error occurs :
"Symbol's function definition is void: R-mode"

That's what you asked for.   I don't have a R-mode either here, but you
know what you're doing.

Thank you again for this fast answer.

The problem is that calling M-x R-mode under emacs usually works.
But while calling R-mode with .emacs, it don't work anymore. And my R-scratch buffer is still in fundamental mode.

If I find any answer, I will post it.

Perhaps M-x R-mode RET asks for parameters?  Type C-h f R-mode RET and
see what's its usage.

C-h f R-mode returns :

"
R-mode is an interactive compiled Lisp function in `ess-r-d.el'.
(R-mode &optional PROC-NAME)
Major mode for editing R source.  See `ess-mode' for more help.
"

and ess-mode returns (first lines) :

"
R-mode is an interactive compiled Lisp function in `ess-r-d.el'.
(R-mode &optional PROC-NAME)
Major mode for editing R source.  See `ess-mode' for more help.
"

I don't think it needed any required argument but I may be wrong...

Indeed, (R-mode) should work.

M-x toggle-debug-on-error RET
and try again.

The problem seems to be solved.
I added (require 'ess-site) in the .emacs file and the code you
published in the second message and the R-scratch buffer is
automatically created in R-mode while opening emacs. I guess this
solve the problem.

Thank you for helping !
