Size of startup files

Size of startup files

[Bob Newell]

Aloha,

This is just a 'curiosity' question as I wonder if I am off
the deep end even for an Emacs user, which would be really
saying something.

I just took a quick look and found that my startup files
(called from .emacs and so on) amount to about 5,000 lines of
elisp.  Of course I comment extensively but at least half of
this or more is actual code.

This has built up over a period of many years.  It may serve
to validate something someone said, more or less that 90% of
Emacs users customize their setup a lot, and the other 10%
customize their setup REALLY a lot.

Mine is 8735 lines but like you much of it commented explanation. I
think org-mode and auctex must account for most of the code.

Best wishes,

My configuration weighs 3358 LOC.  The number *excludes* comments, for I
have none.  I tangle the it from a 51,712-LOC Org notebook that contains
all Emacs configuration and notes I have, along with other notes.

Without comments (I use org to generate my .el init files), I have a
little over 4000 lines of elisp code built up over the past 4 decades.

Thanks for the interesting replies.  Perhaps unsurprisingly,
it demonstrates again just how "personal" emacs is and how it
becomes more and more so over time.

However, I think the extent of it would stagger the
uninitiated, and this raises a practical point.  When
attracting newcomers to emacs, they need to hear that you
don't have to eat the elephant whole, and that with time and
experience they will find their own best ways.

My init file never reached that size: I think around the time it was
inching its way toward 2k lines, I decided I should change Emacs
instead.

So in a sense, my init file is now somewhere around 2M lines :-(

On the contrary, that's good for all of us!

But on the whole, it is not a sane situation. What we should
have is a set of libraries that have very basic and
self-explicatory names, then it would be so easy to find out
if some functionality is already available - and if not, where
to add it ...

For example, I'd like to have a math library for thing like
the blow Elisp, which I have in my own Elisp at the moment ...

(defalias '**   #'expt)
(defalias 'ceil #'ceiling)

(defun // (nom denom)
  (/ nom denom 1.0) )

;; (/  8 256) ; 0 *oups*
;; (// 8 256) ; 0.03125

(defun mean-value (vs)
  (let*((sum  (apply #'+ vs))
        (mean (/ sum (length vs) 1.0)) )
    mean) )

(defun percent (nom &optional denom str)
  (or denom (setq denom 1))
  (let ((perc (/ nom denom 0.01)))
    (if str
        (format "%.1f%%" perc)
      perc)))

;; (percent 0.25)           ; 25.0
;; (percent 50 75)          ; 66.66 ...
;; (percent (// 1 2) nil t) ; 50.0%
;; (percent 1019 22 t)      ; 4631.8%

And if we had such a library, maybe someone would improve this
by makin the string branch output with the correct number of
significant digits!

It's just an example, but it's a good one as it makes sense.

It should be like this:

* Everyone does their own customization (obviously)

* Everyone does their own original/creative projects (or ditto
  just-for-fun elisping)

* But everyone should not do this basic stuff over and over,
  instead it should be found in libraries - incomplete and
  poor as they may be day one, in time they will be improved
  to become a huge asset.

I attempt to cleanup the init file very frequently... every quarter may
be. And the total number of lines is <1k. Not many comments in my file.

For example,

1. I removed code to install eglot, now that it is available as a
   builtin feature.

2. Earlier I wrote a function to toggle themes. Now it is builtin.

And after use-package's inclusion, the file size will further reduce.

Good point.

I guess one way to look at it is that, given my numbers (a little over
4000 lines of customization but using Emacs since mid 80s), I have added
100 lines of customization approximately per year.  Not that much... ;-)

(shameless-plug

In the Elisp book I wrote last year I included a fairly simple code to
count SLOC, excluding blank lines and comment-only lines.  Why not try
this on your init file?

--8<---------------cut here---------------start------------->8---
; -*- lexical-binding: t; -*-

(defun count-sloc--count-lines-if (predicate begin end)
  "Count lines satisfying PREDICATE from BEGIN to END.
PREDICATE should accept no arguments."
  (save-excursion
    (save-restriction
      (narrow-to-region begin end)
      (goto-char begin)
      (let ((count 0))
	(while (not (eobp))
	  (when (funcall predicate)
	    (setq count (1+ count)))
	  (forward-line))
	count))))

(defun count-sloc--act-on-region-or-buffer (func message)
  "Perform FUNC on region or buffer and print MESSAGE.
FUNC should accept two arguments, the beginning and end of the
range it operates on.  If MESSAGE contains
a placeholder (e.g. \"%s\"), the return value of FUNC is
substituted for it."
  (let (begin end)
    (if (use-region-p)
	(setq begin (region-beginning) end (region-end))
      (setq begin (point-min) end (point-max)))
    (message message (funcall func begin end))))

(defun count-sloc--comment-or-blank-line-p ()
  "Return t if the point is at a comment line.
Assume that the point is at the beginning of line."
  (unless (nth 3 (syntax-ppss))
    (save-excursion
      (let ((orig-line-number (line-number-at-pos)))
	(forward-comment 1000)
	(or (not (eq orig-line-number (line-number-at-pos)))
	    (eobp))))))

(defun count-sloc--negate (fun)
  "Return a function returning the logical opposite of FUN."
  (lambda (&rest args)
    (not (apply fun args))))

(defun count-sloc ()
  "Count non-blank lines in the region or buffer."
  (interactive)
  (count-sloc--act-on-region-or-buffer
   (apply-partially #'count-sloc--count-lines-if
		    (count-sloc--negate
		     #'count-sloc--comment-or-blank-line-p))
   "Non-blank lines: %s"))
--8<---------------cut here---------------end--------------->8---

My init.el is 1591 lines long (excluding comment/blank lines) and 2317
lines including them.  (But it includes a few other files.)  Also, my
init.el is /very/ messy (I will make it better Some Day™.)

)

Best,

Re: Size of startup files

[Jean Louis]

If the init file loads other libraries, then those libraries shall
also be included in counting of startup line sizes.

If we speak of loaded libraries, then instead of asking for line
sizes, it is better to ask people which libraries they constantly use.

I have separated customized variables in ~/.emacs.d/custom.el and it's
size is 653 lines. I do not program it neither change that file, it is
managed by {M-x customize}

I use for example:

(require 'dired-x)
(require 'facemenu)
(require 'enriched)
(require 'gold-price)
(require 'persistent-scratch nil t)
(require 'rcd-password)
(require 'rcd-db-basics)
(require 'rcd-cf)
(require 'windmove)
(require 'rcd-vc)
(load "image-stamp")
(load "rcd-dict")
(load "units")

plus Hyperbole and some additional library. I must have that for
personal work.

I have just tried: M-x toggle-theme and I get error:

toggle-theme: Theme ‘light-blue’ does not have any known variants

This may be because 

 '(custom-enabled-themes '(light-blue))

So toggle-theme should have better working.

But they are part of the source - why not? So this is 5 lines

  /****************/
  /* add one to i */
  /****************/

  i++;

just as this

  int i = 0; printf('%d %d', i, i++);

is 1 line.

So all you have to do to count you Elisp SLOC, all files, is

  $ wc -l ~/.emacs.d/emacs-init/**/*.el | awk 'END { print $1 }'

9314

You misunderstand the mechanism by which toggle-theme works.  A theme
may declare a family:

  (deftheme tsdh-light
    "A light Emacs theme.
  Used and created by Tassilo Horn."
    :background-mode 'light
    :kind 'color-scheme
    :family 'tsdh)

When a theme of this family is enabled, M-x toggle-theme will either
prompt the user or toggle the theme to some other member of the family
automatically (the latter works if there are only two themes to switch
between).

This is nice, no need for modus-themes-toggle in modus-themes.

There was an attempt to deprecate that command in favour of
toggle-theme, but Prot decided against it:
