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

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

197 #+end_src
198
199 ** Package management
200
201 *** No =package.el=
202
203 I can do all my package management things with Borg, and don't need
204 Emacs' built-in =package.el=. Emacs 27 lets us disable =package.el= in
205 the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
206
207 #+begin_src emacs-lisp :tangle early-init.el
208 (setq package-enable-at-startup nil)
209 #+end_src
210
211 But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
212 right now), and even when released it'll be long before most distros
213 ship in their repos, I'll still put the old workaround with the
214 commented call to ~package-initialize~ here anyway.
215
216 #+begin_src emacs-lisp
217 (setq package-enable-at-startup nil)
218 ;; (package-initialize)
219 #+end_src

221 *** Borg

223 #+begin_quote
224 Assimilate Emacs packages as Git submodules
225 #+end_quote
226
227 [[https://github.com/emacscollective/borg][Borg]] is at the heart of package management of my Emacs setup. In
228 short, it creates a git submodule in =lib/= for each package, which
229 can then be managed with the help of Magit or other tools.
230
231 #+begin_src emacs-lisp

256 #+end_quote
257
258 [[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
259 packages (in our case especially the latter) in a neatly organized way
260 and without compromising on performance.
261
262 #+begin_src emacs-lisp
263 (require 'use-package)
264 (if nil ; set to t when need to debug init
265 (setq use-package-verbose t

272
273 *** Epkg
274
275 #+begin_quote

277 #+end_quote
278
279 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
280 database, low-level functions for querying the database, and a
281 =package.el=-like user interface for browsing the available packages.
282
283 #+begin_src emacs-lisp
284 (use-package epkg
285 :defer t
286 :bind
287 (("C-c b d" . epkg-describe-package)

293
294 #+begin_quote
295 Help keeping ~/.emacs.d clean
296 #+end_quote
297
298 By default, even for Emacs' built-in packages, the configuration files
299 and persistent data are all over the place. Use =no-littering= to help
300 contain the mess.
301
302 #+begin_src emacs-lisp
303 (use-package no-littering
304 :demand t
305 :config

311 #+end_src
312
313 ** Custom file (=custom.el=)
314
315 I'm not planning on using the custom file much, but even so, I
316 definitely don't want it mixing with =init.el=. So, here; let's give
317 it it's own file. While at it, treat themes as safe.
318
319 #+begin_src emacs-lisp
320 (use-package custom
321 :no-require t
322 :config
323 (setq custom-file (no-littering-expand-etc-file-name "custom.el"))
324 (when (file-exists-p custom-file)
325 (load custom-file))
326 (setf custom-safe-themes t))
327 #+end_src
328
329 ** Secrets file

331 Load the secrets file if it exists, otherwise show a warning.
332

336 #+end_src
337
338 ** Better =$PATH= handling
339
340 Let's use [[https://github.com/purcell/exec-path-from-shell][exec-path-from-shell]] to make Emacs use the =$PATH= as set up
341 in my shell.
342
343 #+begin_src emacs-lisp

363 ** Server
364
365 Start server if not already running. Alternatively, can be done by
366 issuing =emacs --daemon= in the terminal, which can be automated with
367 a systemd service or using =brew services start emacs= on macOS. I use
368 Emacs as my window manager (via EXWM), so I always start Emacs on
369 login; so starting the server from inside Emacs is good enough for me.
370

502 using the Xfce panel anymore. Also, I don't need to see the load
503 average on a regular basis, so disable that.

574 Now let's customize the =*scratch*= buffer a bit. First off, I don't
575 need the default hint.
576
577 #+begin_src emacs-lisp
578 (setq initial-scratch-message nil)
579 #+end_src
580
581 Also, let's use Text mode as the major mode, in case I want to
582 customize it (=*scratch*='s default major mode, Fundamental mode,
583 can't really be customized).
584
585 #+begin_src emacs-lisp
586 (setq initial-major-mode 'text-mode)
587 #+end_src
588
589 Inhibit the buffer list when more than 2 files are loaded.

592 (setq inhibit-startup-buffer-menu t)
593 #+end_src
594

596 either.

2240 Manually install bbdb (=lisp/bbdb= copied from an ELPA-based setup),
2241 because installing it from source on Emacs 27 using the following
2242 submodule configuration for some reason doesn’t work and results in
2243 very strange errors when using any of the functions.
