11 This org file is my literate configuration for GNU Emacs, and is
12 tangled to [[./init.el][init.el]]. Packages are installed and managed using
13 [[https://github.com/emacscollective/borg][Borg]]. Over the years, I've taken inspiration from configurations of
14 many different people. Some of the configurations that I can remember
15 off the top of my head are:
16
17 - [[https://github.com/dieggsy/dotfiles][dieggsy/dotfiles]]: literate Emacs and dotfiles configuration, uses
18 straight.el for managing packages
19 - [[https://github.com/dakra/dmacs][dakra/dmacs]]: literate Emacs configuration, using Borg for managing
20 packages
21 - [[http://pages.sachachua.com/.emacs.d/Sacha.html][Sacha Chua's literate Emacs configuration]]
22 - [[https://github.com/dakrone/eos][dakrone/eos]]
23 - Ryan Rix's [[http://doc.rix.si/cce/cce.html][Complete Computing Environment]] ([[http://doc.rix.si/projects/fsem.html][about cce]])
24 - [[https://github.com/jwiegley/dot-emacs][jwiegley/dot-emacs]]: nix-based configuration
25 - [[https://github.com/wasamasa/dotemacs][wasamasa/dotemacs]]
26 - [[https://github.com/hlissner/doom-emacs][Doom Emacs]]
27
28 I'd like to have a fully reproducible Emacs setup (part of the reason
29 why I store my configuration in this repository) but unfortunately out
30 of the box, that's not achievable with =package.el=, not currently
31 anyway. So, I've opted to use Borg. For what it's worth, I briefly
32 experimented with [[https://github.com/raxod502/straight.el][straight.el]], but found that it added about 2 seconds
33 to my init time; which is unacceptable for me: I use Emacs as my
34 window manager (via EXWM) and coming from bspwm, I'm too used to
35 having fast startup times.
36
37 ** Installation
38
39 To use this config for your Emacs, first you need to clone this repo,
40 then bootstrap Borg, tell Borg to retrieve package submodules, and
41 byte-compiled the packages. Something along these lines should work:
42
43 #+begin_src sh :tangle no
44 git clone https://github.com/aminb/dotfiles ~/.emacs.d
45 cd ~/.emacs.d
46 make bootstrap-borg
47 make bootstrap
48 make build

79 that =init.el= is an auto-generated file, not supposed to be edited),
80 and provides some convenient key bindings for browsing through the

117
118 ** Emacs initialization
119
120 I'd like to do a couple of measurements of Emacs' startup time. First,
121 let's see how long Emacs takes to start up, before even loading
122 =init.el=, i.e. =user-init-file=:
123
124 #+begin_src emacs-lisp
125 (defvar a/before-user-init-time (current-time)
126 "Value of `current-time' when Emacs begins loading `user-init-file'.")
127 (message "Loading Emacs...done (%.3fs)"
128 (float-time (time-subtract a/before-user-init-time
129 before-init-time)))
130 #+end_src
131
132 Also, temporarily increase ~gc-cons-threshhold~ and
133 ~gc-cons-percentage~ during startup to reduce garbage collection
134 frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
135 startup time as well.
136
137 #+begin_src emacs-lisp
138 (defvar a/gc-cons-threshold gc-cons-threshold)
139 (defvar a/gc-cons-percentage gc-cons-percentage)
140 (defvar a/file-name-handler-alist file-name-handler-alist)
141 (setq gc-cons-threshold (* 400 1024 1024) ; 400 MiB
142 gc-cons-percentage 0.6
143 file-name-handler-alist nil
144 ;; sidesteps a bug when profiling with esup
145 esup-child-profile-require-level 0)
146 #+end_src
147
148 Of course, we'd like to set them back to their defaults once we're
149 done initializing.
150
151 #+begin_src emacs-lisp
152 (add-hook
153 'after-init-hook
154 (lambda ()
155 (setq gc-cons-threshold a/gc-cons-threshold
156 gc-cons-percentage a/gc-cons-percentage
157 file-name-handler-alist a/file-name-handler-alist)))
158 #+end_src
159
160 Increase the number of lines kept in message logs (the =*Messages*=
161 buffer).
162
163 #+begin_src emacs-lisp
164 (setq message-log-max 20000)
165 #+end_src
166
167 Optionally, we could suppress some byte compiler warnings like below,
168 but for now I've decided to keep them enabled. See documentation for
169 ~byte-compile-warnings~ for more details.
170
171 #+begin_src emacs-lisp

182
183 ** Package management
184
185 *** No =package.el=
186
187 I can do all my package management things with Borg, and don't need
188 Emacs' built-in =package.el=. Emacs 27 lets us disable =package.el= in
189 the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
190
191 #+begin_src emacs-lisp :tangle early-init.el
192 (setq package-enable-at-startup nil)
193 #+end_src
194
195 But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
196 right now), and even when released it'll be long before most distros
197 ship in their repos, I'll still put the old workaround with the
198 commented call to ~package-initialize~ here anyway.
199
200 #+begin_src emacs-lisp
201 (setq package-enable-at-startup nil)

209 #+end_quote
210
211 [[https://github.com/emacscollective/borg][Borg]] is at the heart of package management of my Emacs setup. In
212 short, it creates a git submodule in =lib/= for each package, which
213 can then be managed with the help of Magit or other tools.
214

240 #+end_quote
241
242 [[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
243 packages (in our case especially the latter) in a neatly organized way
244 and without compromising on performance.
245

257 *** Epkg
258
259 #+begin_quote

261 #+end_quote
262
263 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
264 database, low-level functions for querying the database, and a
265 =package.el=-like user interface for browsing the available packages.
266
267 #+begin_src emacs-lisp
268 (use-package epkg

282
283 #+begin_quote

285 #+end_quote
286
287 By default, even for Emacs' built-in packages, the configuration files
288 and persistent data are all over the place. Use =no-littering= to help
289 contain the mess.
290
291 #+begin_src emacs-lisp
292 (use-package no-littering
293 :demand t
294 :config

300 #+end_src
301
302 ** Custom file (=custom.el=)
303
304 I'm not planning on using the custom file much, but even so, I
305 definitely don't want it mixing with =init.el=. So, here; let's give
306 it it's own file. While at it, treat themes as safe.
307
308 #+begin_src emacs-lisp
309 (use-package custom
310 :no-require t
311 :config
312 (setq custom-file (no-littering-expand-etc-file-name "custom.el"))

314 (load custom-file))
315 (setf custom-safe-themes t))
316 #+end_src
317
318 ** Secrets file

320 Load the secrets file if it exists, otherwise show a warning.

325 #+end_src
326
327 ** Better =$PATH= handling
328
329 Let's use [[https://github.com/purcell/exec-path-from-shell][exec-path-from-shell]] to make Emacs use the =$PATH= as set up
330 in my shell.
331
332 #+begin_src emacs-lisp
333 (use-package exec-path-from-shell
334 :defer 1

342 #+end_src

349 (mapc #'disable-theme custom-enabled-themes))
350 #+end_src
351
352 ** Server
353
354 Start server if not already running. Alternatively, can be done by
355 issuing =emacs --daemon= in the terminal, which can be automated with
356 a systemd service or using =brew services start emacs= on macOS. I use
357 Emacs as my window manager (via EXWM), so I always start Emacs on
358 login; so starting the server from inside Emacs is good enough for me.
359
360 See [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Emacs-Server.html#Emacs-Server][Using Emacs as a Server]].

474
475 *** Time and battery in mode-line
476
477 Enable displaying time and battery in the mode-line, since I'm not
478 using the Xfce panel anymore. Also, I don't need to see the load
479 average on a regular basis, so disable that.
480
481 Note: using =i3status= on sway at the moment, so disabling this.

505 *** Disable disabled commands
506
507 Emacs disables some commands by default that could persumably be
508 confusing for novice users. Let's disable that.
509
510 #+begin_src emacs-lisp
511 (setq disabled-command-function nil)
512 #+end_src
513
514 *** Kill-ring
515
516 Save what I copy into clipboard from other applications into Emacs'
517 kill-ring, which would allow me to still be able to easily access it
518 in case I kill (cut or copy) something else inside Emacs before
519 yanking (pasting) what I'd originally intended to.

532 *** Lazy-person-friendly yes/no prompts
533
534 Lazy people would prefer to type fewer keystrokes, especially for yes
535 or no questions. I'm lazy.

541 *** Startup screen and =*scratch*=
542
543 Firstly, let Emacs know that I'd like to have =*scratch*= as my
544 startup buffer.
545
546 #+begin_src emacs-lisp
547 (setq initial-buffer-choice t)
548 #+end_src
549
550 Now let's customize the =*scratch*= buffer a bit. First off, I don't
551 need the default hint.
552
553 #+begin_src emacs-lisp
554 (setq initial-scratch-message nil)
555 #+end_src
556
557 Also, let's use Text mode as the major mode, in case I want to
558 customize it (=*scratch*='s default major mode, Fundamental mode,
559 can't really be customized).
560
561 #+begin_src emacs-lisp
562 (setq initial-major-mode 'text-mode)
563 #+end_src
564
565 Inhibit the buffer list when more than 2 files are loaded.
566
567 #+begin_src emacs-lisp
568 (setq inhibit-startup-buffer-menu t)
569 #+end_src
570
571 I don't really need to see the startup screen or echo area message
572 either.
