;;; Commentary:

;; This package prints name of function where your current point is
;; located in mode line.  It assumes that you work with the imenu
;; package and `imenu--index-alist' is up to date.

;; KNOWN BUGS
;; ----------
;; Really this package shows not "function where the current point is
;; located now", but "nearest function which defined above the current
;; point".  So if your current point is located after the end of
;; function FOO but before the beginning of function BAR, FOO will be
;; displayed in the mode line.
;; - If two windows display the same buffer, both windows
;;   show the same `which-func' information.

;; TODO LIST
;; ---------
;;     1. Dependence on imenu package should be removed.  Separate
;; function determination mechanism should be used to determine the end
;; of a function as well as the beginning of a function.
;;     2. This package should be realized with the help of overlay
;; properties instead of the `imenu--index-alist' variable.

;; THANKS TO
;; ---------
;; Per Abrahamsen   <abraham@iesd.auc.dk>
;;     Some ideas (inserting  in mode-line,  using of post-command  hook
;;     and toggling this  mode) have  been   borrowed from  his  package
;;     column.el
;; Peter Eisenhauer <pipe@fzi.de>
;;     Bug fixing in case nested indexes.
;; Terry Tateyama   <ttt@ursa0.cs.utah.edu>
;;     Suggestion to use find-file-hook for first imenu
;;     index building.
