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

71 Enable =view-mode=, which both makes the file read-only (as a reminder
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.

127 ** Emacs initialization
128
129 I'd like to do a couple of measurements of Emacs' startup time. First,
130 let's see how long Emacs takes to start up, before even loading
131 =init.el=, i.e. =user-init-file=:
132
133 #+begin_src emacs-lisp
134 (defvar amin--before-user-init-time (current-time)
135 "Value of `current-time' when Emacs begins loading `user-init-file'.")
136 (message "Loading Emacs...done (%.3fs)"
137 (float-time (time-subtract amin--before-user-init-time
138 before-init-time)))
139 #+end_src
140
141 Also, temporarily increase ~gc-cons-threshhold~ and
142 ~gc-cons-percentage~ during startup to reduce garbage collection
143 frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
144 startup time as well.
145
146 #+begin_src emacs-lisp
147 (defvar amin--gc-cons-threshold gc-cons-threshold)
148 (defvar amin--gc-cons-percentage gc-cons-percentage)
149 (defvar amin--file-name-handler-alist file-name-handler-alist)
150 (setq gc-cons-threshold (* 400 1024 1024) ; 400 MiB
151 gc-cons-percentage 0.6
152 file-name-handler-alist nil
153 ;; sidesteps a bug when profiling with esup
154 esup-child-profile-require-level 0)
155 #+end_src
156
157 Of course, we'd like to set them back to their defaults once we're
158 done initializing.
159
160 #+begin_src emacs-lisp
161 (add-hook
162 'after-init-hook
163 (lambda ()
164 (setq gc-cons-threshold amin--gc-cons-threshold
165 gc-cons-percentage amin--gc-cons-percentage
166 file-name-handler-alist amin--file-name-handler-alist)))
167 #+end_src
168
169 Increase the number of lines kept in message logs (the =*Messages*=
170 buffer).
171
172 #+begin_src emacs-lisp
173 (setq message-log-max 20000)
174 #+end_src
175
176 Optionally, we could suppress some byte compiler warnings like below,
177 but for now I've decided to keep them enabled. See documentation for
178 ~byte-compile-warnings~ for more details.
179
180 #+begin_src emacs-lisp
181 ;; (setq byte-compile-warnings
182 ;; '(not free-vars unresolved noruntime lexical make-local))

190 #+end_src
191
192 ** Package management
193
194 *** No =package.el=
195
196 I can do all my package management things with Borg, and don't need
197 Emacs' built-in =package.el=. Emacs 27 lets us disable =package.el= in
198 the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
199
200 #+begin_src emacs-lisp :tangle early-init.el
201 (setq package-enable-at-startup nil)
202 #+end_src
203
204 But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
205 right now), and even when released it'll be long before most distros
206 ship in their repos, I'll still put the old workaround with the
207 commented call to ~package-initialize~ here anyway.
208
209 #+begin_src emacs-lisp
210 (setq package-enable-at-startup nil)
211 ;; (package-initialize)
212 #+end_src

216 #+begin_quote
217 Assimilate Emacs packages as Git submodules
218 #+end_quote
219
220 [[https://github.com/emacscollective/borg][Borg]] is at the heart of package management of my Emacs setup. In
221 short, it creates a git submodule in =lib/= for each package, which
222 can then be managed with the help of Magit or other tools.
223
224 #+begin_src emacs-lisp

249 #+end_quote
250
251 [[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
252 packages (in our case especially the latter) in a neatly organized way
253 and without compromising on performance.
254
255 #+begin_src emacs-lisp
256 (require 'use-package)
257 (if nil ; set to t when need to debug init
258 (setq use-package-verbose t

265
266 *** Epkg
267
268 #+begin_quote

270 #+end_quote
271
272 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
273 database, low-level functions for querying the database, and a
274 =package.el=-like user interface for browsing the available packages.
275
276 #+begin_src emacs-lisp
277 (use-package epkg
278 :defer t

286
287 #+begin_quote

289 #+end_quote
290
291 By default, even for Emacs' built-in packages, the configuration files
292 and persistent data are all over the place. Use =no-littering= to help
293 contain the mess.
294
295 #+begin_src emacs-lisp
296 (use-package no-littering

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

318 (load custom-file))
319 (setf custom-safe-themes t))
320 #+end_src

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

331 ** Better =$PATH= handling
332
333 Let's use [[https://github.com/purcell/exec-path-from-shell][exec-path-from-shell]] to make Emacs use the =$PATH= as set up
334 in my shell.
335
336 #+begin_src emacs-lisp

354 #+end_src
355
356 ** Server
357
358 Start server if not already running. Alternatively, can be done by
359 issuing =emacs --daemon= in the terminal, which can be automated with
360 a systemd service or using =brew services start emacs= on macOS. I use
361 Emacs as my window manager (via EXWM), so I always start Emacs on
362 login; so starting the server from inside Emacs is good enough for me.
363
364 See [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Emacs-Server.html#Emacs-Server][Using Emacs as a Server]].

2186 ** bbdb
2187
2188 Manually install bbdb (=lisp/bbdb= copied from an ELPA-based setup),
2189 because installing it from source on Emacs 27 using the following
2190 submodule configuration for some reason doesn’t work and results in
2191 very strange errors when using any of the functions.

2205 I tried using =borg-elpa= instead of doing it like this, but it added
2206 2 seconds to my startup time, which is unacceptable to me.
