Subject: vbb-mode for GNU Emacs
Date: 5 Sep 2002 04:44:30 -0700 [thread overview]
Message-ID: <2f83b0dc.0209050344.53b5fb21@posting.google.com> (raw)
Hello,
there is a minor-mode for X-Emacs called vvb-mode which shows a
vertikal bar in a certain column (eg column 72).
Sadly it works only with X-Emacs.
1. Is there a similar package for GNU Emacs?
2. Does anyone know of version of vbb-mode.el for GNU Emacs?
3. Has anyone an idea how to get this part of code working with GNU
emacs?
;; show the bar
(let ((column (current-column))
(case-fold-search nil)
)
(if (>= column vvb-column)
(if vvb-visible-p
nil
(let ((start (window-start))
(end (window-end))
(cnt 0)
)
(save-excursion
(goto-char start)
(while (<= (point) end)
(move-to-column vvb-column)
(if (<= vvb-column (current-column))
(let (b e)
(setq b (point))
(if vvb-right-on-eol-p
(progn (end-of-line)
(setq e (point)))
(setq e (1+ b)))
(set-extent-properties (make-extent b e)
(list 'face vvb-face
'vvb t))
(setq cnt (1+ cnt))))
(or (search-forward "\n" nil t)
(setq end -1))))
(if (> cnt 0)
(setq vvb-visible-p t))
))
;;else - clean up previous act if any
(vvb-hide))
)
)
;; attach it to the XEmacs system
(or (assoc 'vvb-mode minor-mode-alist)
(setq minor-mode-alist (cons '(vvb-mode " VBar")
minor-mode-alist)))
This is a code snippet from an early version of vvb-mode.el available
at
http://www.ee.ed.ac.uk/~ssp/Info/Email_and_News/Emacs/msg00036.html
The whole file is not very long, and the rest of it is pretty straight
forward.
If I load vbb-mode.el emacs does not complain, its just that the bar
does not
show up.
There are more recent versions of it, but i don't need the
functionality.
The more recent versions give me some errors with GNU Emacs.
