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))

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)

254 A use-package declaration for simplifying your .emacs
255 #+end_quote
256
257 [[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
258 packages (in our case especially the latter) in a neatly organized way
259 and without compromising on performance.
260

262 (require 'use-package)
263 (if nil ; set to t when need to debug init
264 (setq use-package-verbose t

271
272 *** Epkg
273
274 #+begin_quote
275 Browse the Emacsmirror package database
276 #+end_quote
277
278 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
279 database, low-level functions for querying the database, and a
280 =package.el=-like user interface for browsing the available packages.
281
282 #+begin_src emacs-lisp
283 (use-package epkg
284 :defer t
285 :bind
286 (("C-c b d" . epkg-describe-package)

289 #+end_src

291 ** No littering in =~/.emacs.d=
292
293 #+begin_quote
294 Help keeping ~/.emacs.d clean
295 #+end_quote
296
297 By default, even for Emacs' built-in packages, the configuration files
298 and persistent data are all over the place. Use =no-littering= to help
299 contain the mess.
300
301 #+begin_src emacs-lisp
302 (use-package no-littering
303 :demand t
304 :config

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

330 #+begin_src emacs-lisp

334 ** Better =$PATH= handling
335
336 Let's use [[https://github.com/purcell/exec-path-from-shell][exec-path-from-shell]] to make Emacs use the =$PATH= as set up
337 in my shell.
338
339 #+begin_src emacs-lisp
340 (use-package exec-path-from-shell

359 ** Server
360
361 Start server if not already running. Alternatively, can be done by
362 issuing =emacs --daemon= in the terminal, which can be automated with
363 a systemd service or using =brew services start emacs= on macOS. I use
364 Emacs as my window manager (via EXWM), so I always start Emacs on
365 login; so starting the server from inside Emacs is good enough for me.
366

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

516 *** Kill-ring
517
518 Save what I copy into clipboard from other applications into Emacs'
519 kill-ring, which would allow me to still be able to easily access it
520 in case I kill (cut or copy) something else inside Emacs before

558
559 Also, let's use Text mode as the major mode, in case I want to
560 customize it (=*scratch*='s default major mode, Fundamental mode,
561 can't really be customized).
562
563 #+begin_src emacs-lisp
564 (setq initial-major-mode 'text-mode)

566
567 Inhibit the buffer list when more than 2 files are loaded.
