;; Copyright (C) 2010, 2012 David Engster

;; You should have received a copy of the GNU General Public License
;; along with this program. If not, see <http://www.gnu.org/licenses/>.
;;; Commentary:
;; This is to easily profile your Emacs init file (or any other
;; script-like Emacs Lisp file, for that matter).
;; It will go over all sexp's (balanced expressions) in the file and
;; run them through `benchmark-run'. It will then show the file with
;; overlays applied in a way that let you easily find out which sexp's
;; take the most time. Since time is relative, it's not the absolute
;; value that counts but the percentage of the total running time.
;;
;; * All other sexp's with a percentage greater than
;; `profile-dotemacs-low-percentage' will be preceded by a
;; highlighted line, showing the results from `benchmark-run'.
;; Also, the more 'reddish' the background of the sexp, the more
;; time it needs.
;; * All other sexp's will be grayed out to indicate that their
;; running time is miniscule. You can still see the benchmark
;; results in the minibuffer by hovering over the sexp with the
;; mouse.
;; You can only benchmark full sexp's, so if you wrapped large parts
;; of your init file in some conditional clause, you'll have to remove
;; that for getting finer granularity.
;;; Usage:
;; Start emacs as follows:
;;
;; emacs -Q -l <PATH>/profile-dotemacs.el -f profile-dotemacs
;;
;; with <PATH> being the path to where this file resides.
;;; Caveats (thanks to Raffaele Ricciardi for reporting those):
;; - The usual `--debug-init' for debugging your init file won't work
;; with profile-dotemacs, so you'll have to call
;; `toggle-debug-on-error', either on the commandline or at the
;; beginning of your init file.
;; - `load-file-name' is nil when the init file is being loaded
;; by the profiler. This might matter if you perform the
;; bulk of initializations in a different file.
;; - Starting external shells like IELM or eshell in your init file
;; might mess with overlay creation, so this must not be done.
;;; Download:
;; You can always get the latest version from
;; http://randomsample.de/profile-dotemacs.el
