is it possible to customise what headline level which-function displays?

is it possible to customise what headline level which-function displays?

[Eric S Fraga]

Hello all,

I have started using which-function (now that I have a monitor big
enough for my emacs mode-line... ;-).  I was pleasantly surprised to see
that org supports which-function out of the box, although I shouldn't by
now be surprised at anything that org does.

Anyway, a quick question: which-function for org files seems to only
keep track of second level headings (or first level in some cases).  My
documents often have three levels and I would like to have the third
level, or even a hierarchical representation (e.g. "first -> second ->
third") shown.  I have not been able to figure out how which-function picks up the
information it displays.  Is there any way to customise org to display
different information?

Thanks,
eric

`which-function' uses `imenu--index-alist' so you can
change the value of `org-imenu-depth' from 2 to 3 to get
what you want (not tested.)

HTH,

This seems to work, in that it does look deeper in the
hierarchy.  Thanks.  Makes which-function much more useful for me.

However, in playing around, I have found what seems to be a bug, at
least for the which-function functionality (not sure about imenu as I
don't use that directly).  If you have a hierarchy that looks like this:

#+begin_src org
  ,* A
  ,** A.1
  ,* B
  We have some text here and point is |here.
#+end_src

then which-function thinks we are in A.1 when point is where
indicated.  This is the case with the default value of org-imenu-depth.

Not a big issue but I thought I'd point it out in case it matters for
imenu usage.  It could be a which-function issue in any case.

Thanks again,
eric

Surely an issue with Emacs, as I can't reproduce the problem here
with latest Emacs.
