|
||||
|
||||
;;; 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.
