vc-checkin (RCS) always. Problem with vc-checkin

[Uwe Brauer]

Hello


I asked this some days ago in Emacs.help. However the answer given did
not work of me, so I hope somebody in this list might now the answer.



http://www.emacswiki.org/emacs/VersionControlAlways

(defun ensure-in-vc-or-check-in ()
  "Automatically checkin file ,v can be in the same directory or in the
subdirectory RCS. The idea is  to call that function only for files
not for buffers. See the function ensure-in-vc-or-check-in-modes  
which could be use in an apropriate HOOK."
  (interactive)
  (when (buffer-file-name)   
	(if (or (and (file-exists-p (format "%s,v" (buffer-file-name))))
(and (file-exists-p (format "RCS/%s,v" (file-name-nondirectory buffer-file-name)))))
  (let ((p (point)))
		(progn
			(vc-checkin (buffer-file-name) nil "")
			(vc-toggle-read-only) 
			(message "Checked in"))
		    (goto-char p))
	  (progn
		  (message "You need to check this in! ")))))


The point is the code works for a old version of VC, however for GNU
emacs 25
(vc-checkin (buffer-file-name) nil "")

does not work any more.

The docstring for the old function said:
(vc-checkin FILE &optional REV COMMENT INITIAL-CONTENTS)
file for the new function:
(vc-checkin FILES BACKEND &optional COMMENT INITIAL-CONTENTS)
so I thought

(vc-checkin (buffer-file-name) 'RCS nil "")
or
(vc-checkin (buffer-file-name) 'RCS  "")

Should work, however it does not. The following error is given
 vc-delistify seems the culprit, but I am stack.


Thanks

vc-checkin expects a list as the first argument.

This was suggested to me
	    (vc-call-backend  'RCS  'checkin (list (buffer-file-name)) "") 
and did not work,

While 
	    (vc-checkin (list (buffer-file-name)) 'RCS " ")

works now, I swear it did not last week with GNU Emacs 24, now I am
using the actual git version

Thanks

Hello

The following code can be found in

http://www.emacswiki.org/emacs/VersionControlAlways

(defun ensure-in-vc-or-check-in ()
  "Automatically checkin file ,v can be in the same directory or in the
subdirectory RCS. The idea is  to call that function only for files
not for buffers. See the function ensure-in-vc-or-check-in-modes  
which could be use in an apropriate HOOK."
  (interactive)
  (when (buffer-file-name)   
	(if (or (and (file-exists-p (format "%s,v" (buffer-file-name))))
			(and (file-exists-p (format "RCS/%s,v" (file-name-nondirectory buffer-file-name)))))
  (let ((p (point)))
		(progn
			(vc-checkin (buffer-file-name) nil "")
			(vc-toggle-read-only) 
			(message "Checked in"))
		    (goto-char p))
	  (progn
		  (message "You need to check this in! ")))))

I modified the original code
by adding (format "RCS/%s,v" (file-name-nondirectory buffer-file-name)



The point is the code works for a old version of VC, however for GNU
emacs 25
(vc-checkin (buffer-file-name) nil "")

does not work any more.

The docstring for the old function said:
(vc-checkin FILE &optional REV COMMENT INITIAL-CONTENTS)
file for the new function:
(vc-checkin FILES BACKEND &optional COMMENT INITIAL-CONTENTS)
so I thought

(vc-checkin (buffer-file-name) 'RCS nil "")
or
(vc-checkin (buffer-file-name) 'RCS  "")

Should work, it does not. The following error is given
 vc-delistify seems the culprit, but I am stack.

  Ok that the form I know. backend is required.

  In fact it does not work. vc-checkin launches a very
  complicated process of interaction opening the log buffer to
  setup the check in message. In fact if you do not want this
  process to run interactively vc-checkin is maybe not the
  right method. You might replace your code by :

  (vc-call-backend 'RCS 'checkin (list (buffer-file-name)) "")

  Sure it won't accomplish certain tasks around check in
  performed by vc-checkin but if yuou only want to check in
  ....

Not sure whether my message went through. I don't see it that is why I
resend it.

Hm it does not work work me.
In a file which is under version control I
used eval-last-sexp for
(vc-call-backend 'RCS 'checkin (list (buffer-file-name)) "")

and I obtained: the following error message

ci: missing message for -m option


Did you try this command out?

Uwe

   Hm it does not work work me.
   In a file which is under version control I
   used eval-last-sexp for
   (vc-call-backend 'RCS 'checkin (list (buffer-file-name)) "")

   and I obtained: the following error message

   ci: missing message for -m option

In lisp/vc/vc.el, the generic ‘checkin’ signature is documented
as (reproduced here):

 checkin (files rev comment)

 Commit changes in FILES to this backend.  REV is a historical artifact
 and should be ignored.  COMMENT is used as a check-in comment.
 The implementation should pass the value of vc-checkin-switches to
 the backend command.

(If you don't have Emacs Lisp installed as part of the Emacs
installation, stop reading, obtain that, then return here.)
Thus, the above invocation receives the parms:

 FILES -- (list (buffer-file-name))
 REV   -- ""

and COMMENT is unspecified.  Another approach, a bit higher in
abstraction, would be to use ‘vc-rcs-checkin’ directly.  Its
docstring in my old (2014-01-01) copy is not so useful, but the
*Help* buffer produced by ‘C-h f vc-rcs-checkin RET’ shows the
same signature described above; you can probably figure it out.
