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

132 ** Emacs initialization
133
134 I'd like to do a couple of measurements of Emacs' startup time. First,
135 let's see how long Emacs takes to start up, before even loading
136 =init.el=, i.e. =user-init-file=:
137
138 #+begin_src emacs-lisp
139 (defvar amin--before-user-init-time (current-time)
140 "Value of `current-time' when Emacs begins loading `user-init-file'.")
141 (message "Loading Emacs...done (%.3fs)"
142 (float-time (time-subtract amin--before-user-init-time
143 before-init-time)))
144 #+end_src
145
146 Also, temporarily increase ~gc-cons-threshhold~ and
147 ~gc-cons-percentage~ during startup to reduce garbage collection
148 frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
149 startup time as well.
150
151 #+begin_src emacs-lisp
152 (defvar amin--gc-cons-threshold gc-cons-threshold)
153 (defvar amin--gc-cons-percentage gc-cons-percentage)
154 (defvar amin--file-name-handler-alist file-name-handler-alist)
155 (setq gc-cons-threshold (* 400 1024 1024) ; 400 MiB
156 gc-cons-percentage 0.6
157 file-name-handler-alist nil
158 ;; sidesteps a bug when profiling with esup
159 esup-child-profile-require-level 0)
160 #+end_src
161
162 Of course, we'd like to set them back to their defaults once we're
163 done initializing.
164
165 #+begin_src emacs-lisp
166 (add-hook
167 'after-init-hook
168 (lambda ()
169 (setq gc-cons-threshold amin--gc-cons-threshold
170 gc-cons-percentage amin--gc-cons-percentage
171 file-name-handler-alist amin--file-name-handler-alist)))
172 #+end_src
173
174 Increase the number of lines kept in message logs (the =*Messages*=
175 buffer).
176
177 #+begin_src emacs-lisp
178 (setq message-log-max 20000)
179 #+end_src
180
181 Optionally, we could suppress some byte compiler warnings like below,
182 but for now I've decided to keep them enabled. See documentation for
183 ~byte-compile-warnings~ for more details.
184
185 #+begin_src emacs-lisp
186 ;; (setq byte-compile-warnings
187 ;; '(not free-vars unresolved noruntime lexical make-local))
188 #+end_src
189
190 ** whoami
191

193 (setq user-full-name "Amin Bandali"
194 user-mail-address "amin@aminb.org")
195 #+end_src
196
197 ** Package management
198
199 *** No =package.el=
200
201 I can do all my package management things with Borg, and don't need
202 Emacs' built-in =package.el=. Emacs 27 lets us disable =package.el= in
203 the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
204
205 #+begin_src emacs-lisp :tangle early-init.el
206 (setq package-enable-at-startup nil)
207 #+end_src
208
209 But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
210 right now), and even when released it'll be long before most distros
211 ship in their repos, I'll still put the old workaround with the
212 commented call to ~package-initialize~ here anyway.
213
214 #+begin_src emacs-lisp
215 (setq package-enable-at-startup nil)
216 ;; (package-initialize)
217 #+end_src
218
219 *** Borg
220
221 #+begin_quote
222 Assimilate Emacs packages as Git submodules
223 #+end_quote
224
225 [[https://github.com/emacscollective/borg][Borg]] is at the heart of package management of my Emacs setup. In
226 short, it creates a git submodule in =lib/= for each package, which
227 can then be managed with the help of Magit or other tools.
228
229 #+begin_src emacs-lisp
230 (setq user-init-file (or load-file-name buffer-file-name)
231 user-emacs-directory (file-name-directory user-init-file))
232 (add-to-list 'load-path
233 (expand-file-name "lib/borg" user-emacs-directory))
234 (require 'borg)
235 (borg-initialize)
236 #+end_src
237
238 *** =use-package=
239
240 #+begin_quote
241 A use-package declaration for simplifying your .emacs
242 #+end_quote
243
244 [[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
245 packages (in our case especially the latter) in a neatly organized way
246 and without compromising on performance.
247
248 #+begin_src emacs-lisp
249 (require 'use-package)
250 (if nil ; set to t when need to debug init
251 (setq use-package-verbose t
252 use-package-expand-minimally nil
253 use-package-compute-statistics t
254 debug-on-error t)
255 (setq use-package-verbose nil
256 use-package-expand-minimally t))
257 #+end_src
258
259 *** Epkg
260
261 #+begin_quote
262 Browse the Emacsmirror package database
263 #+end_quote
264
265 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
266 database, low-level functions for querying the database, and a
267 =package.el=-like user interface for browsing the available packages.
268
269 #+begin_src emacs-lisp
270 (use-package epkg
271 :defer t)
272 #+end_src
273
274 ** No littering in =~/.emacs.d=
275
276 #+begin_quote
277 Help keeping ~/.emacs.d clean
278 #+end_quote
279
280 By default, even for Emacs' built-in packages, the configuration files
281 and persistent data are all over the place. Use =no-littering= to help
282 contain the mess.
283
284 #+begin_src emacs-lisp
285 (use-package no-littering
286 :demand t
287 :config
288 (savehist-mode 1)
289 (add-to-list 'savehist-additional-variables 'kill-ring)
290 (save-place-mode 1)
291 (setq auto-save-file-name-transforms
292 `((".*" ,(no-littering-expand-var-file-name "auto-save/") t))))
293 #+end_src
294
295 ** Custom file (=custom.el=)
296
297 I'm not planning on using the custom file much, but even so, I
298 definitely don't want it mixing with =init.el=. So, here; let's give
299 it it's own file. While at it, treat themes as safe.
300
301 #+begin_src emacs-lisp
302 (use-package custom
303 :no-require t
304 :config
305 (setq custom-file (no-littering-expand-etc-file-name "custom.el"))
306 (when (file-exists-p custom-file)
307 (load custom-file))
308 (setf custom-safe-themes t))
309 #+end_src
310
311 ** Better =$PATH= handling
312
313 Let's use [[https://github.com/purcell/exec-path-from-shell][exec-path-from-shell]] to make Emacs use the =$PATH= as set up
314 in my shell.
315
316 #+begin_src emacs-lisp
317 (use-package exec-path-from-shell
318 :defer 1
319 :init
320 (setq exec-path-from-shell-check-startup-files nil)
321 :config
322 (exec-path-from-shell-initialize)
323 ;; while we're at it, let's fix access to our running ssh-agent
324 (exec-path-from-shell-copy-env "SSH_AGENT_PID")
325 (exec-path-from-shell-copy-env "SSH_AUTH_SOCK"))
326 #+end_src
327
328 ** Only one custom theme at a time
329
330 #+begin_src emacs-lisp
331 (defadvice load-theme (before clear-previous-themes activate)
332 "Clear existing theme settings instead of layering them"
333 (mapc #'disable-theme custom-enabled-themes))
334 #+end_src
335
336 ** Server
337
338 Start server if not already running. Alternatively, can be done by
339 issuing =emacs --daemon= in the terminal, which can be automated with
340 a systemd service or using =brew services start emacs= on macOS. I use
341 Emacs as my window manager (via EXWM), so I always start Emacs on
342 login; so starting the server from inside Emacs is good enough for me.
343
344 See [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Emacs-Server.html#Emacs-Server][Using Emacs as a Server]].
345
346 #+begin_src emacs-lisp
347 (use-package server

349 #+end_src

437
438 *** Time and battery in mode-line
439
440 Enable displaying time and battery in the mode-line, since I'm not
441 using the Xfce panel anymore. Also, I don't need to see the load
442 average on a regular basis, so disable that.
443
444 Note: using =i3status= on sway at the moment, so disabling this.

462 Might want to set the fringe to a smaller value, especially if using
463 EXWM. I'm fine with the default for now.
464
465 #+begin_src emacs-lisp
466 ;; (fringe-mode '(3 . 1))
467 (fringe-mode nil)
468 #+end_src
469
470 *** Disable disabled commands
471
472 Emacs disables some commands by default that could persumably be
473 confusing for novice users. Let's disable that.
474
475 #+begin_src emacs-lisp
476 (setq disabled-command-function nil)
477 #+end_src
478
479 *** Kill-ring
480
481 Save what I copy into clipboard from other applications into Emacs'
482 kill-ring, which would allow me to still be able to easily access it
483 in case I kill (cut or copy) something else inside Emacs before
484 yanking (pasting) what I'd originally intended to.
485

495 #+end_src
496
497 *** Lazy-person-friendly yes/no prompts
498
499 Lazy people would prefer to type fewer keystrokes, especially for yes
500 or no questions. I'm lazy.
501
502 #+begin_src emacs-lisp
503 (defalias 'yes-or-no-p #'y-or-n-p)
504 #+end_src
505
506 *** Startup screen and =*scratch*=
507
508 Firstly, let Emacs know that I'd like to have =*scratch*= as my
509 startup buffer.
510
511 #+begin_src emacs-lisp
512 (setq initial-buffer-choice t)
513 #+end_src
514
515 Now let's customize the =*scratch*= buffer a bit. First off, I don't
516 need the default hint.
517
518 #+begin_src emacs-lisp
519 (setq initial-scratch-message nil)
520 #+end_src
521
522 Also, let's use Text mode as the major mode, in case I want to
523 customize it (=*scratch*='s default major mode, Fundamental mode,
524 can't really be customized).
525
526 #+begin_src emacs-lisp
527 (setq initial-major-mode 'text-mode)
528 #+end_src
529
530 Inhibit the buffer list when more than 2 files are loaded.
531
532 #+begin_src emacs-lisp
533 (setq inhibit-startup-buffer-menu t)
534 #+end_src
535
536 I don't really need to see the startup screen or echo area message
537 either.
538
539 #+begin_src emacs-lisp
540 (advice-add #'display-startup-echo-area-message :override #'ignore)
541 (setq inhibit-startup-screen t
542 inhibit-startup-echo-area-message user-login-name)
543 #+end_src
544
545 *** More useful frame titles
546
547 Show either the file name or the buffer name (in case the buffer isn't
548 visiting a file). Borrowed from Emacs Prelude.
549
550 #+begin_src emacs-lisp
551 (setq frame-title-format
552 '("" invocation-name " - "
553 (:eval (if (buffer-file-name)
554 (abbreviate-file-name (buffer-file-name))
555 "%b"))))
556 #+end_src
557
558 *** Backups
559
560 Emacs' default backup settings aren't that great. Let's use more
561 sensible options. See documentation for the ~make-backup-file~
562 variable.
563
564 #+begin_src emacs-lisp
565 (setq backup-by-copying t
566 version-control t)
567 #+end_src
568
569 *** Auto revert
570
571 Enable automatic reloading of changed buffers and files.
572
573 #+begin_src emacs-lisp
