Subject: what-page and first line of page?
Date: Mon, 14 Sep 2009 12:42:53 +0200 [thread overview]
Message-ID: <87tyz5ajte.fsf@x2.delysid.org> (raw)
Hi.
I am editiing a long document where original page numbers are important.
When I use `what-page' to see to which physical page the position
of point currently corresponds, I notice that it does not
work on the first line which starts with ^L. I.e.:
line 1 or page 1
\fline 2 of page 1
line 1 of page 2
To make `what-page' return the correct page number I either
always have to immediately follow ^L with a newline, or
remove `beginning-of-line' in the definition of `what-page':
(defun what-page ()
"Print page and line number of point."
(interactive)
(save-restriction
(widen)
(save-excursion
;(beginning-of-line)
(let ((count 1)
(opoint (point)))
(goto-char 1)
(while (re-search-forward page-delimiter opoint t)
(setq count (1+ count)))
(message "Page %d, line %d"
count
(1+ (count-lines (point) opoint)))))))
I am arguing this is a bug. Does anyone know why
the `beginning-of-line' is actually in there?
