[Ebib-users] Multiline fields in Index Entry

[Massimo L. <lau...@gm...>]

Hi guy,

I have an issue with ebib.  I set up the Index Display Fields
to show
Year; Author; Title.

Sometimes these fields are multiline (notice that i've no full control
of all .bib files).
This results in some entries to span several lines in the index buffer.

This produces two bugs:
- (minor) only one line of the entry is highlighted
- (major)
when I move up/down or using whatever keys trigger ebib-prev/next-entry,
the prev/next entry is correctly shown in the Entry buffer, but the
cursor only moves one line up/down.
Since there are entries spanning more than one line, this completely
disconnect position in the database with the
cursor position in the  index buffer.


The following is a dirty hack workaround which print only the first
line of a multiline field in the index entries.

(defun ebib-display-entry (entry-key)
  "Displays ENTRY-KEY in the index buffer at POINT."
  (set-buffer ebib-index-buffer)
  (insert (format "%-30s %s\n"
		  entry-key
		  (if ebib-index-display-fields
		      (let ((cur-entry-hash (ebib-retrieve-entry entry-key ebib-cur-db)))
			(mapconcat #'(lambda (field)
				       (or
					(to-raw (let (
                                  (str (gethash field cur-entry-hash))
                                  )
                              (if (multiline-p str)
                                  (first-line str)
                                str
                                ))
                            )
					""))
				   ebib-index-display-fields
				   "; "))
		    ""))))

The correct solution maybe using something different that
(forward-line -1/+1) in ebib-prev/next-entry:
something like searching backward/forward for the first line beginning
with the new displayed entry.
Another less robust solution is to search  backward/forward for a line
beginning with a character, because all lines
of fields displayed in the index buffer are indented.


Thank you
