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

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

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

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))

244 ("C-c B a" . borg-assimilate)
245 ("C-c B b" . borg-build)
246 ("C-c B c" . borg-clone)))
247 #+end_src
248
249 *** =use-package=
250
251 #+begin_quote
252 A use-package declaration for simplifying your .emacs
253 #+end_quote
254
255 [[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
256 packages (in our case especially the latter) in a neatly organized way
257 and without compromising on performance.
258
259 #+begin_src emacs-lisp
260 (require 'use-package)
261 (if nil ; set to t when need to debug init
262 (setq use-package-verbose t
263 use-package-expand-minimally nil
264 use-package-compute-statistics t

266 (setq use-package-verbose nil
267 use-package-expand-minimally t))
268 #+end_src
269
270 *** Epkg
271
272 #+begin_quote
273 Browse the Emacsmirror package database
274 #+end_quote
275
276 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
277 database, low-level functions for querying the database, and a
278 =package.el=-like user interface for browsing the available packages.
279
280 #+begin_src emacs-lisp
281 (use-package epkg
282 :defer t
283 :bind
284 (("C-c B d" . epkg-describe-package)
285 ("C-c B p" . epkg-list-packages)
286 ("C-c B r" . borg-remove)
287 ("C-c B u" . epkg-update)))
288 #+end_src
289
290 ** No littering in =~/.emacs.d=
291
292 #+begin_quote
293 Help keeping ~/.emacs.d clean
294 #+end_quote
295
296 By default, even for Emacs' built-in packages, the configuration files
297 and persistent data are all over the place. Use =no-littering= to help
298 contain the mess.
299
300 #+begin_src emacs-lisp
301 (use-package no-littering
302 :demand t
303 :config
304 (savehist-mode 1)
305 (add-to-list 'savehist-additional-variables 'kill-ring)
306 (save-place-mode 1)
307 (setq auto-save-file-name-transforms
308 `((".*" ,(no-littering-expand-var-file-name "auto-save/") t))))
309 #+end_src
310
311 ** Custom file (=custom.el=)
312
313 I'm not planning on using the custom file much, but even so, I
314 definitely don't want it mixing with =init.el=. So, here; let's give
315 it it's own file. While at it, treat themes as safe.
316
317 #+begin_src emacs-lisp
318 (use-package custom
319 :no-require t
320 :config
321 (setq custom-file (no-littering-expand-etc-file-name "custom.el"))
322 (when (file-exists-p custom-file)
323 (load custom-file))
324 (setf custom-safe-themes t))
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
335 :init
336 (setq exec-path-from-shell-check-startup-files nil)
337 :config
338 (exec-path-from-shell-initialize)
339 ;; while we're at it, let's fix access to our running ssh-agent
340 (exec-path-from-shell-copy-env "SSH_AGENT_PID")
341 (exec-path-from-shell-copy-env "SSH_AUTH_SOCK"))
342 #+end_src
343
344 ** Only one custom theme at a time
345
346 #+begin_src emacs-lisp
347 (defadvice load-theme (before clear-previous-themes activate)
348 "Clear existing theme settings instead of layering them"
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

470
471 Enable displaying time and battery in the mode-line, since I'm not
472 using the Xfce panel anymore. Also, I don't need to see the load
473 average on a regular basis, so disable that.
474

495 ;; (fringe-mode '(3 . 1))
496 (fringe-mode nil)
497 #+end_src

499 *** Disable disabled commands
500
501 Emacs disables some commands by default that could persumably be
502 confusing for novice users. Let's disable that.
503
504 #+begin_src emacs-lisp
505 (setq disabled-command-function nil)
506 #+end_src
507
508 *** Kill-ring
509
510 Save what I copy into clipboard from other applications into Emacs'
511 kill-ring, which would allow me to still be able to easily access it
512 in case I kill (cut or copy) something else inside Emacs before
513 yanking (pasting) what I'd originally intended to.

524 #+end_src
525
526 *** Lazy-person-friendly yes/no prompts
527
528 Lazy people would prefer to type fewer keystrokes, especially for yes
529 or no questions. I'm lazy.

535 *** Startup screen and =*scratch*=
536
537 Firstly, let Emacs know that I'd like to have =*scratch*= as my
538 startup buffer.
539
540 #+begin_src emacs-lisp
541 (setq initial-buffer-choice t)
542 #+end_src
543
544 Now let's customize the =*scratch*= buffer a bit. First off, I don't
545 need the default hint.
546
547 #+begin_src emacs-lisp
548 (setq initial-scratch-message nil)
549 #+end_src
550
551 Also, let's use Text mode as the major mode, in case I want to
552 customize it (=*scratch*='s default major mode, Fundamental mode,
553 can't really be customized).
554
555 #+begin_src emacs-lisp
556 (setq initial-major-mode 'text-mode)
557 #+end_src
558
559 Inhibit the buffer list when more than 2 files are loaded.
560
561 #+begin_src emacs-lisp
562 (setq inhibit-startup-buffer-menu t)
563 #+end_src
564
565 I don't really need to see the startup screen or echo area message
566 either.
567
