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
37 To use this config for your Emacs, first you need to clone this repo,
38 then tangle =init.org= into =init.el=, and optionally byte-compile
39 =init.el=.
40
41 First, clone the repository and =cd= into it:
42
43 #+begin_src sh :tangle no
44 git clone https://git.sr.ht/~bandali/dotfiles ~/.emacs.d
45 cd ~/.emacs.d
46 #+end_src
47
48 Then, decide if you would like to use a byte-compiled init file, and
49 set the following variable accordingly:
50
51 #+begin_src emacs-lisp
52 (defvar a/byte-compiled-init t
53 "If non-nil, byte-(re)compile init.el on successful tangles.")
54 #+end_src
55
56 Now, first tangle =init.org=, and only if you chose to have a
57 byte-compiled init, build init as well:
58
59 #+begin_src sh :tangle no
60 make tangle-init
61 make build-init
62 #+end_src
63
64 If you'd like to use a byte-compiled init, it's important that it be
65 recompiled whenever =init.el= is generated from an updated =init.org=.
66 Not only does my setup automatically and asynchronously tangle
67 =init.org= to =init.el= every time you edit and save =init.org= in GNU
68 Emacs, it will also invoke =make build-init= if you set
69 =a/byte-compiled-init= to =t= above, so you wouldn't have to worry
70 about manually tangling and compiling your init file whenever you
71 change it. The output of the last byte-compilation in the current
72 session is kept in a =*compilation*= buffer, which will automatically
73 be displayed if compilation fails.

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

142 ** Emacs initialization
143
144 I'd like to do a couple of measurements of Emacs' startup time. First,
145 let's see how long Emacs takes to start up, before even loading
146 =init.el=, i.e. =user-init-file=:
147
148 #+begin_src emacs-lisp
149 (defvar a/before-user-init-time (current-time)
150 "Value of `current-time' when Emacs begins loading `user-init-file'.")
151 (message "Loading Emacs...done (%.3fs)"
152 (float-time (time-subtract a/before-user-init-time
153 before-init-time)))
154 #+end_src
155
156 Also, temporarily increase ~gc-cons-threshhold~ and
157 ~gc-cons-percentage~ during startup to reduce garbage collection
158 frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
159 startup time as well.
160
161 #+begin_src emacs-lisp
162 (defvar a/gc-cons-threshold gc-cons-threshold)
163 (defvar a/gc-cons-percentage gc-cons-percentage)
164 (defvar a/file-name-handler-alist file-name-handler-alist)
165 (setq gc-cons-threshold (* 400 1024 1024) ; 400 MiB
166 gc-cons-percentage 0.6
167 file-name-handler-alist nil
168 ;; sidesteps a bug when profiling with esup
169 esup-child-profile-require-level 0)
170 #+end_src
171
172 Of course, we'd like to set them back to their defaults once we're
173 done initializing.
174
175 #+begin_src emacs-lisp
176 (add-hook
177 'after-init-hook
178 (lambda ()
179 (setq gc-cons-threshold a/gc-cons-threshold
180 gc-cons-percentage a/gc-cons-percentage
181 file-name-handler-alist a/file-name-handler-alist)))
182 #+end_src
183
184 Increase the number of lines kept in message logs (the =*Messages*=
185 buffer).
186
187 #+begin_src emacs-lisp
188 (setq message-log-max 20000)
189 #+end_src
190
191 Optionally, we could suppress some byte compiler warnings like below,
192 but for now I've decided to keep them enabled. See documentation for
193 ~byte-compile-warnings~ for more details.
194
195 #+begin_src emacs-lisp
196 ;; (setq byte-compile-warnings
197 ;; '(not free-vars unresolved noruntime lexical make-local))

206
207 ** Package management
208
209 *** No =package.el=
210
211 I can do all my package management things with =straight.el=, and
212 don't need Emacs' built-in =package.el=. Emacs 27 lets us disable
213 =package.el= in the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
214
215 #+begin_src emacs-lisp :tangle early-init.el
216 (setq package-enable-at-startup nil)
217 #+end_src
218
219 But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
220 right now), and even when released it'll be long before most distros
221 ship in their repos, I'll still put the old workaround with the
222 commented call to ~package-initialize~ here anyway.
223
224 #+begin_src emacs-lisp :tangle no
225 (setq package-enable-at-startup nil)
226 ;; (package-initialize)
227 #+end_src
228
229 Update: the above is not necessary, since =straight.el= automatically
230 does that (and more). See =straight-package-neutering-mode=.
231
232 *** =straight.el=

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

360 I'm not planning on using the custom file much, but even so, I

411 Start server if not already running. Alternatively, can be done by
412 issuing =emacs --daemon= in the terminal, which can be automated with
413 a systemd service or using =brew services start emacs= on macOS. I use
414 Emacs as my window manager (via EXWM), so I always start Emacs on
415 login; so starting the server from inside Emacs is good enough for me.

571 *** Kill-ring
572
573 Save what I copy into clipboard from other applications into Emacs'
574 kill-ring, which would allow me to still be able to easily access it
575 in case I kill (cut or copy) something else inside Emacs before
576 yanking (pasting) what I'd originally intended to.

598 *** Startup screen and =*scratch*=
599
600 Firstly, let Emacs know that I'd like to have =*scratch*= as my
601 startup buffer.
602
603 #+begin_src emacs-lisp
604 (setq initial-buffer-choice t)
605 #+end_src
606
607 Now let's customize the =*scratch*= buffer a bit. First off, I don't
608 need the default hint.
609
610 #+begin_src emacs-lisp
611 (setq initial-scratch-message nil)
612 #+end_src
613
614 Also, let's use Text mode as the major mode, in case I want to
615 customize it (=*scratch*='s default major mode, Fundamental mode,
616 can't really be customized).
617
618 #+begin_src emacs-lisp
619 (setq initial-major-mode 'text-mode)
620 #+end_src
621
622 Inhibit the buffer list when more than 2 files are loaded.
623
624 #+begin_src emacs-lisp
625 (setq inhibit-startup-buffer-menu t)
626 #+end_src
627
628 I don't really need to see the startup screen or echo area message
629 either.

632 (advice-add #'display-startup-echo-area-message :override #'ignore)

637 *** More useful frame titles

648 #+end_src
649
650 *** Backups
651
652 Emacs' default backup settings aren't that great. Let's use more

829 In short, my favourite way of life.

831 First, we have to resort to a [[https://github.com/raxod502/straight.el#installing-org-with-straightel][hack]] to be able to use the correct
