Extra parameter for define-obsolete-function-alias

Hi:

Recent changes in define-obsolete-function-alias requires an extra parameter to indicate the obsoletion time.

Provide a release tarball

Hello,

Could you provide a release tarball, please?

Just add a tag, for example: 1.0. Then make a git push --tags.

Thanks,
Oleg.

Problem: not showing all processes

My emacs takes over 30 seconds to load. However, when I run benchmark-init, I only see a few processes and these do not take more than 1 second overall. What is happening?

Hey! Just wanted to leave a comment that this finally got me to track down the two big cost centers (during startup) for my Emacs setup -- solarized/color and flycheck. Thanks a bunch! Now I can use terminal Emacs for interactive git rebase without being constantly annoyed.

Make compatible with literate init files

I use an Org-mode init file, so everything gets tangled into main.el first. So when I run benchmark-init-el, I get a single big entry:

  ~/log/config/org/main.el                                          load       2358    5093

Is there a way to get more granular benchmarking here without replaying the generated main.el file?

Error: Wrong number of arguments

Trying to install this package using straight. If I just eval a use-package call for it, e.g.

(use-package benchmark-init
  :demand)

I get (wrong-number-of-arguments (3 . 4) 2). Here's the backtrace:

I'm on Emacs 28.0.90.

Should the README file be updated to load benchmark-init-modes.el?

In order to make everything work, I had to put
(let ((benchmark-init.el "/path/to/el-get/benchmark-init/benchmark-init-modes.el"))
(when (file-exists-p benchmark-init.el)
(load benchmark-init.el)))
in my .emacs instead of the lines described in the README file.

Debugger entered--Lisp error: (void-function benchmark-init/show-durations-tabulated)

I'm trying to follow the instructions for setting up benchmark-init, but I can't tabulate the benchmark results.

Download

$ cd ~/Desktop/src/
$ git clone [email protected]:dholm/benchmark-init-el.git

Configuration

https://github.com/mcandre/dotfiles/blob/benchmark/.emacs

I relaunched Emacs. Twice.

Then I tried to run (benchmark-init/show-durations-tabulated), Emacs complains that it can't find this function. Tab completion shows several functions for M-: (benchmark-init/..., but show-durations-tabulated is not one of them.

Hmm, does benchmark-init play well with use-package, especially delayed package loading?

Makefile missing, benchmark-init-loaddefs.el not created

I installed benchmark-init thanks to ELPA and, AFAICS, it has been put in ~/.emacs.d/elpa/benchmark-init-20150905.238:

$ ls -1  ~/.emacs.d/elpa/benchmark-init-20150905.238
benchmark-init-autoloads.el
benchmark-init.el
benchmark-init.elc
benchmark-init-modes.el
benchmark-init-modes.elc
benchmark-init-pkg.el

But, the Makefile is missing. If I add it manually:

$ make
make: nothing to do for « all ».

but no benchmark-init-loaddefs.el file produced.

Error: (error "Lisp nesting exceeds `max-lisp-eval-depth'")

Improvement to package loading instructions

This is just a comment on improving the suggested method of loading the code when installed via el-get or the package manager. Currently the README suggests

(let ((benchmark-init.el "/path/to/el-get/benchmark-init/benchmark-init.el"))
  (when (file-exists-p benchmark-init.el)
    (load benchmark-init.el)))

however the load function has options to not report an error if the file exists. Also by default it will start by trying to add extensions .elc and .el to the file name. I suggest you shorten the code to

(let ((benchmark-init-el "/path/to/el-get/benchmark-init/benchmark-init.el")
  (load benchmark-init-el 'no-error nil 'no-suffix))

or even to a single load statement

(load "/path/to/el-get/benchmark-init/benchmark-init.el"
  'no-error nil 'no-suffix)

M-x emacs-init-time is 1.6s, but benchmark-init/root is 899ms

The emacs internal data of initial time is logger than benchmark.I guess something cause it.
I have used the
;; time the loading of the .emacs ;; keep this on top of your .emacs (defvar *emacs-load-start* (current-time)) (defun anarcat/time-to-ms (time) (+ (* (+ (* (car time) (expt 2 16)) (car (cdr time))) 1000000) (car (cdr (cdr time))))) (defun anarcat/display-timing () (message ".emacs loaded in %fms" (/ (- (anarcat/time-to-ms (current-time)) (anarcat/time-to-ms *emacs-load-start*)) 1000000.0))) (add-hook 'after-init-hook 'anarcat/display-timing t)

which from http://www.emacswiki.org/emacs/OptimizingEmacsStartup
The result is very close to emacs-init-time and more precise.
Could benchmark-init be colser to emacs-init-time， and tell us what happend between the 1600ms-899ms?

Sort by total ms

Can I sort the items in benchmark-init/show-durations-tabulated by total ms rather than ms?
