slow bibtex menu access

slow bibtex menu access

[Sebastian Luque]

Clicking on any item in my bibtex menu while editing *.bib files is taking
outrageously long times on my system:

GNU Emacs 21.3.1 (i386-pc-linux-gnu, X toolkit, Xaw3d scroll bars) of
2005-02-03 on trouble, modified by Debian

I've tried setting bibtex-maintain-sorted-entries to t and nil, but it
doesn't make a difference. It seems to be related to the size of the file,
as when I edit a blank or a few-entries long *.bib there's no problem. My
main reference file is 23,761 lines and that's when the menu is pretty
much unuseable. Does somebody know how to get around this?

Thanks,

What do you want to do when "clicking on any item in my bibtex

bibtex.el has been rewritten extensively. You might want to try the
CVS version. (However, this requires CVS emacs.)

Anything, really, and now I've realized that it doesn't really affect the
bibtex menu, but any menu. Simply clicking on the menu bar hangs all of
Emacs for 30-60 s. Last night I realized the time increases according to
the line the cursor is on (no problems in the first few hundred lines).
Looks like a memory issue.

Excuse my ignorance, what is CVS Emacs? I've heard the term before, but
that's about it. OTOH, is that bibtex.el planned for the next regular
Emacs release? if so, does anybody know when that will happen?

Thank you,

Sorry, I meant "...*only* affect the bibtex menu, but any menu." here

That's strange. I never have had any such problem. (My largest bib
file has ~6000 lines.)

...still strange. I've never noticed anything like that.

Take a look at

It'll be part of the next release, but I don't know when it will
appear.

The one I'm working on has ~23,000 lines, but I don't know if that would
make a difference in your system too. I'll do some tests with different
sized *.bib and see what happens.

I've a >16000 line bib-file here, no problem whatsoever (GNU Emacs
21.3.1)

Have you tried with "emacs -q"?
My crystal ball is pretty fuzzy but it mumbled something about you maybe
adding an index menu (imenu) to the menu bar and setting imenu-auto-rescan.

Not bad! With emacs -q normal bibtex menu-bar functionality was restored.
I do have the index menu enabled, but only for lisp mode buffers; from my
~/.emacs:

(add-hook 'emacs-lisp-mode-hook (quote (turn-on-eldoc-mode imenu-add-menubar-index
 checkdoc-minor-mode)))

(add-hook 'lisp-mode-hook 'imenu-add-menubar-index)


and imenu-auto-rescan is nil. I tried disabling the hooks above anyway
hoping for magic, but clicking the menu-bar while on a large bibtex buffer
is still getting slower with incresing (line-number-at-pos)

Great idea anyway!

If emacs -q gets rid of the problem, the easiest way to proceed is to
find out which part of your .emacs is to blame. You should comment out
the whole file, then uncomment a few pieces at a time and test again,
trying to spot the point where the problem comes back.

Thank you, I'd forgotten that (haven't done it in a long time). So I found
the problem, and it was table.el. I had (require 'table) and (require
'emacs-wiki-table) (the latter requires table.el) in a few places. I have
no idea where and how table.el is causing the problem, but would it be
possible to turn it off (I guess a hook might do it) while in bibtex?
Tables are not needed in bibtex anyway.

Thanks for your help,

Setting debug-on-quit and hitting C-g while the menu is being built
indicates that the time is actually spent in table--find-row-column.

Looking some more at the table.el code, it seems there is a minor
logic-thinko bug in it.  Can you try the patch below (it's against the
Emacs-CVS version of table.el, so you may have to apply the patch by hand).

Tak, is my reasoning correct that `table--probe-cell' should return non-nil
iff we're inside a table?
