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

133 ** Emacs initialization
134
135 I'd like to do a couple of measurements of Emacs' startup time. First,
136 let's see how long Emacs takes to start up, before even loading
137 =init.el=, i.e. =user-init-file=:
138
139 #+begin_src emacs-lisp
140 (defvar ab--before-user-init-time (current-time)
141 "Value of `current-time' when Emacs begins loading `user-init-file'.")
142 (message "Loading Emacs...done (%.3fs)"
143 (float-time (time-subtract ab--before-user-init-time
144 before-init-time)))
145 #+end_src
146
147 Also, temporarily increase ~gc-cons-threshhold~ and
148 ~gc-cons-percentage~ during startup to reduce garbage collection
149 frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
150 startup time as well.
151
152 #+begin_src emacs-lisp
153 (defvar ab--gc-cons-threshold gc-cons-threshold)
154 (defvar ab--gc-cons-percentage gc-cons-percentage)
155 (defvar ab--file-name-handler-alist file-name-handler-alist)
156 (setq gc-cons-threshold (* 400 1024 1024) ; 400 MiB
157 gc-cons-percentage 0.6
158 file-name-handler-alist nil
159 ;; sidesteps a bug when profiling with esup
160 esup-child-profile-require-level 0)
161 #+end_src
162
163 Of course, we'd like to set them back to their defaults once we're
164 done initializing.
165
166 #+begin_src emacs-lisp
167 (add-hook
168 'after-init-hook
169 (lambda ()
170 (setq gc-cons-threshold ab--gc-cons-threshold
171 gc-cons-percentage ab--gc-cons-percentage
172 file-name-handler-alist ab--file-name-handler-alist)))
173 #+end_src
174
175 Increase the number of lines kept in message logs (the =*Messages*=
176 buffer).
177
178 #+begin_src emacs-lisp
179 (setq message-log-max 20000)
180 #+end_src
181
182 Optionally, we could suppress some byte compiler warnings like below,
183 but for now I've decided to keep them enabled. See documentation for
184 ~byte-compile-warnings~ for more details.
185
186 #+begin_src emacs-lisp
187 ;; (setq byte-compile-warnings
188 ;; '(not free-vars unresolved noruntime lexical make-local))
189 #+end_src
190
191 ** whoami
192

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

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

463 Might want to set the fringe to a smaller value, especially if using
464 EXWM. I'm fine with the default for now.
465
466 #+begin_src emacs-lisp
467 ;; (fringe-mode '(3 . 1))
468 (fringe-mode nil)
469 #+end_src
470
471 *** Disable disabled commands
472
473 Emacs disables some commands by default that could persumably be
474 confusing for novice users. Let's disable that.
475
476 #+begin_src emacs-lisp
477 (setq disabled-command-function nil)
478 #+end_src
479
480 *** Kill-ring
481
482 Save what I copy into clipboard from other applications into Emacs'
483 kill-ring, which would allow me to still be able to easily access it
484 in case I kill (cut or copy) something else inside Emacs before
485 yanking (pasting) what I'd originally intended to.
486

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