Hello
Lately I use vc-annotate quite often with RCS.
I would find it very useful if from the vc-annotate buffer I
could jump directly to a specific line of the file.
Example I execute vc-annotate in the workfile version and I
obtain
2011-03-22 1.11: \input{aned10-header-beamer}
2011-03-22 1.5 : %\input{aned10-header-article}
So putting to cursor to the second line I would like to jump
to the line in the corresponding file (which happens to be
line number two of the file.)
Anybody know about such a function?

Something like that (warning: barely tested)
(defun vc-annotate-goto-line ()
(interactive)
(unless (eq major-mode 'vc-annotate-mode)
(error "vc-annotate-goto-line must be used on a VC-Annotate buffer"))
(let* ((name (buffer-name))
(base (and (string-match "Annotate \\(.*\\) (rev" name)
(match-string 1 name)))
(line (save-restriction
(widen)
(line-number-at-pos))))
(with-current-buffer (get-buffer base)
(pop-to-buffer (current-buffer))
(save-restriction
(widen)
(goto-char (point-min))
(forward-line (1- line))
(recenter)))))

Right from a practical point this is what I am looking for,
thanks a lot. It does not jump precisely to the line, but as
close as 4 lines.
Look at this example
VC-annote buffer
2010-03-06 1.7 : \end{itemize}
2010-03-06 1.7 : \end{frame}
2011-03-01 1.10:
2010-03-06 1.7 : \begin{frame}
2010-03-02 1.1 :
2011-03-01 1.10: \only<article>{ Si intentamos conseguir que el} Error Global de
2011-03-01 1.10: Discretización sea del mismo orden que el Error Local de
2011-03-01 1.10: Truncamiento, \only<article>{está claro que} necesitamos que
2011-03-01 1.10: $|x_{0}-a|=O(h^{2})$ y $|x_{1}-x(t_{1})|=O(h^{2})$ en cuyo caso
Cursor is on 1.10 \only<article>{ Si intentamos conseguir que el}
Your functions jumps to line starting with
\end{itemize}
As I said the difference of these for lines are not
important I was just wondering ...
Thanks again.

I don't know. Perhaps you're using visual-line-mode or somesuch?

No, edebug also did not give anything useful. In any case I
suggest to include your function in further releases of vc.

Are you able to reproduce the effect with a file which I can annotate
(one on the Emacs sources, for example)? I'm curious about the
problem, because moving to the right line is straightforward enough
that there shouldn't be any discrepancy.

Please send a "wishlist" bug report so the issue is not forgotten.

I did some more testing and it might be that part of the
problem is hidden deep in my init file. So I have to dig
this out myself.
However I tried emacs -no-init and then the function worked
better. By better I mean it worked fine even in files with a
lot of checkins but only in the branch where the version
number started with 1.X, for version whose version number
started with 2. your function behaved in the way I
described.
I have only access to emacs 22.1 at the moment.
What about taking simple.el?
I think this file should the
same for emacs 22 and 23?
Thanks
Uwe
