Hello
When collaborating with someone I find it useful to use vc
(rcs) and change the login accordingly when I checkin a new
version. The following code does it, but maybe there are
more sophisticated versions possible.
Uwe Brauer
(defvar vc-rcs-ask-for-login nil
"*Variable which allows to change the login Id by a y-or-n question.")
(defun vc-rcs-checkin (file rev comment)
"RCS-specific version of `vc-backend-checkin'. If the variable
vc-rcs-ask-for-login is set to t, function asks for user login.
Useful for collaboration to distinguish different checkins."
;;(interactive "p")
(let ((switches (vc-switches 'RCS 'checkin)))
(let ((old-version (vc-workfile-version file)) new-version
(default-branch (vc-file-getprop file
'vc-rcs-default-branch)))
;; Force branch creation if an appropriate
;; default branch has been set.
(and (not rev)
default-branch
(string-match (concat "^" (regexp-quote old-version) "\\.")
default-branch)
(setq rev default-branch)
(setq switches (cons "-f" switches)))
(if (and (not rev) old-version)
(setq rev (vc-branch-part old-version)))
(apply 'vc-do-command nil 0 "ci" (vc-name file)
;; if available, use the secure check-in option
(and (vc-rcs-release-p "5.6.4") "-j")
(concat (if vc-keep-workfiles "-u" "-r") rev)
(if vc-rcs-ask-for-login
(if (y-or-n-p (format "Do you want to change
the login "))
(concat "-w" (read-string "Enter New
login: "))
(concat "-m" comment)))
(concat "-m" comment)
switches)
(vc-file-setprop file 'vc-workfile-version nil)
;; determine the new workfile version
(set-buffer "*vc*")
(goto-char (point-min))
(when (or (re-search-forward
"new revision: \\([0-9.]+\\);" nil t)
(re-search-forward
"reverting to previous revision \\([0-9.]+\\)"
nil t))
(setq new-version (match-string 1))
(vc-file-setprop file 'vc-workfile-version new-version))
;; if we got to a different branch, adjust the default
;; branch accordingly
(cond
((and old-version new-version
(not (string= (vc-branch-part old-version)
(vc-branch-part
new-version))))
(vc-rcs-set-default-branch file
(if
(vc-trunk-p new-version) nil
(vc-branch-part new-version)))
;; If this is an old RCS release, we might have
;; to remove a remaining lock.
(if (not (vc-rcs-release-p "5.6.2"))
;; exit status of 1 is also accepted.
;; It means that the lock was removed before.
(vc-do-command nil 1 "rcs" (vc-name file)
(concat "-u"
old-version))))))))
