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/raxod502/straight.el][straight.el]]. Over the years, I've taken inspiration from
14 configurations of many different people. Some of the configurations
15 that I can remember 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 =straight.el=. I also used Borg for a
32 few months, but decided to try =straight.el= which allows direct use
33 of the various package archives.
34
35 ** Installation
36 :PROPERTIES:
37 :CUSTOM_ID: installation
38 :END:
39
40 To use this config for your Emacs, first you need to clone this repo,
41 then tangle =init.org= into =init.el=, and optionally byte-compile
42 =init.el=.
43
44 First, clone the repository and =cd= into it:
45
46 #+begin_src sh :tangle no
47 git clone https://git.sr.ht/~bandali/dotfiles ~/.emacs.d
48 cd ~/.emacs.d
49 #+end_src
50
51 Then, decide if you would like to use a byte-compiled init file, and
52 set the [[#byte-compiled-init][a/byte-compiled-init]] variable accordingly.
53
54 Now, first tangle =init.org=, and only if you chose to have a
55 byte-compiled init, build init as well:
56
57 #+begin_src sh :tangle no
58 make tangle-init
59 make build-init
60 #+end_src
61
62 If you'd like to use a byte-compiled init, it's important that it be
63 recompiled whenever =init.el= is generated from an updated =init.org=.
64 Not only does my setup automatically and asynchronously tangle
65 =init.org= to =init.el= every time you edit and save =init.org= in GNU
66 Emacs, it will also invoke =make build-init= if you set
67 =a/byte-compiled-init= to =t= above, so you wouldn't have to worry
68 about manually tangling and compiling your init file whenever you
69 change it. The output of the last byte-compilation in the current
70 session is kept in a =*compilation*= buffer, which will automatically
71 be displayed if compilation fails.

100 Enable =view-mode=, which both makes the file read-only (as a reminder
101 that =init.el= is an auto-generated file, not supposed to be edited),
102 and provides some convenient key bindings for browsing through the
103 file.

144
145 If you would like a byte-compiled init file, set the following
146 variable to ~t~, otherwise set it to ~nil~.
147
148 #+begin_src emacs-lisp
149 (defvar a/byte-compiled-init t
150 "If non-nil, byte-(re)compile init.el on successful tangles.")
151 #+end_src
152

154
155 ** Emacs initialization
156
157 I'd like to do a couple of measurements of Emacs' startup time. First,
158 let's see how long Emacs takes to start up, before even loading
159 =init.el=, i.e. =user-init-file=:
160
161 #+begin_src emacs-lisp
162 (defvar a/before-user-init-time (current-time)
163 "Value of `current-time' when Emacs begins loading `user-init-file'.")
164 (message "Loading Emacs...done (%.3fs)"
165 (float-time (time-subtract a/before-user-init-time
166 before-init-time)))
167 #+end_src
168
169 Also, temporarily increase ~gc-cons-threshhold~ and
170 ~gc-cons-percentage~ during startup to reduce garbage collection
171 frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
172 startup time as well.
173
174 #+begin_src emacs-lisp
175 (defvar a/gc-cons-threshold gc-cons-threshold)
176 (defvar a/gc-cons-percentage gc-cons-percentage)
177 (defvar a/file-name-handler-alist file-name-handler-alist)
178 (setq gc-cons-threshold (* 400 1024 1024) ; 400 MiB
179 gc-cons-percentage 0.6
180 file-name-handler-alist nil
181 ;; sidesteps a bug when profiling with esup
182 esup-child-profile-require-level 0)
183 #+end_src
184
185 Of course, we'd like to set them back to their defaults once we're
186 done initializing.
187
188 #+begin_src emacs-lisp
189 (add-hook
190 'after-init-hook
191 (lambda ()
192 (setq gc-cons-threshold a/gc-cons-threshold
193 gc-cons-percentage a/gc-cons-percentage
194 file-name-handler-alist a/file-name-handler-alist)))
195 #+end_src
196
197 Increase the number of lines kept in message logs (the =*Messages*=
198 buffer).
199
200 #+begin_src emacs-lisp
201 (setq message-log-max 20000)
202 #+end_src
203
204 Optionally, we could suppress some byte compiler warnings like below,
205 but for now I've decided to keep them enabled. See documentation for
206 ~byte-compile-warnings~ for more details.
207
208 #+begin_src emacs-lisp
209 ;; (setq byte-compile-warnings
210 ;; '(not free-vars unresolved noruntime lexical make-local))
211 #+end_src
212
213 ** whoami
214
215 #+begin_src emacs-lisp
216 (setq user-full-name "Amin Bandali"
217 user-mail-address "amin@bndl.org")
218 #+end_src
219
220 ** Package management
221
222 *** No =package.el=
223
224 I can do all my package management things with =straight.el=, and
225 don't need Emacs' built-in =package.el=. Emacs 27 lets us disable
226 =package.el= in the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
227
228 #+begin_src emacs-lisp :tangle early-init.el
229 (setq package-enable-at-startup nil)
230 #+end_src
231
232 But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
233 right now), and even when released it'll be long before most distros
234 ship in their repos, I'll still put the old workaround with the
235 commented call to ~package-initialize~ here anyway.
236
237 #+begin_src emacs-lisp :tangle no
238 (setq package-enable-at-startup nil)
239 ;; (package-initialize)
240 #+end_src
241
242 Update: the above is not necessary, since =straight.el= automatically
243 does that (and more). See =straight-package-neutering-mode=.
244
245 *** =straight.el=

247 #+begin_quote

250 #+end_quote

282 ;; We have lift off!
283
284 (setq straight-use-package-by-default t)
285 #+end_src
286
287 Since we enable =straight.el='s =straight-use-package-by-default=
288 integration, we will define a =use-feature= for plain ole
289 =use-package= without any of the =straight.el= stuff.
290
291 #+begin_src emacs-lisp
292 (defmacro use-feature (name &rest args)

300 Also, here's a useful function for reloading the init file (useful
301 after running =straight-check-all=:
302
303 #+begin_src emacs-lisp
304 (defun a/reload-init ()
305 "Reload init.el."
306 (interactive)
307 (straight-transaction

346 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package

586 *** Time and battery in mode-line
587
588 Enable displaying time and battery in the mode-line, since I'm not
589 using the Xfce panel anymore. Also, I don't need to see the load
590 average on a regular basis, so disable that.
591
592 Note: using =i3status= on sway at the moment, so disabling this.

616 *** Disable disabled commands
617
618 Emacs disables some commands by default that could persumably be
619 confusing for novice users. Let's disable that.
620

622 (setq disabled-command-function nil)
623 #+end_src
624
625 *** Kill-ring
626
627 Save what I copy into clipboard from other applications into Emacs'
628 kill-ring, which would allow me to still be able to easily access it
629 in case I kill (cut or copy) something else inside Emacs before
630 yanking (pasting) what I'd originally intended to.

643 *** Lazy-person-friendly yes/no prompts

646 or no questions. I'm lazy.

651
652 *** Startup screen and =*scratch*=
653
654 Firstly, let Emacs know that I'd like to have =*scratch*= as my
655 startup buffer.
656
657 #+begin_src emacs-lisp
658 (setq initial-buffer-choice t)
659 #+end_src
660
661 Now let's customize the =*scratch*= buffer a bit. First off, I don't
662 need the default hint.
663
664 #+begin_src emacs-lisp
665 (setq initial-scratch-message nil)
666 #+end_src
667
668 Also, let's use Text mode as the major mode, in case I want to
669 customize it (=*scratch*='s default major mode, Fundamental mode,
670 can't really be customized).
671
672 #+begin_src emacs-lisp
673 (setq initial-major-mode 'text-mode)
674 #+end_src
675
676 Inhibit the buffer list when more than 2 files are loaded.
677
678 #+begin_src emacs-lisp
679 (setq inhibit-startup-buffer-menu t)
680 #+end_src
681
682 I don't really need to see the startup screen or echo area message
683 either.

690
691 *** More useful frame titles
692
693 Show either the file name or the buffer name (in case the buffer isn't
694 visiting a file). Borrowed from Emacs Prelude.
695

702 #+end_src
703
704 *** Backups
705
706 Emacs' default backup settings aren't that great. Let's use more
707 sensible options. See documentation for the ~make-backup-file~
708 variable.
