11This org file is my literate configuration for GNU Emacs, and is
12tangled 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
14configurations of many different people. Some of the configurations
15that 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
28I'd like to have a fully reproducible Emacs setup (part of the reason
29why I store my configuration in this repository) but unfortunately out
30of the box, that's not achievable with =package.el=, not currently
31anyway. So, I've opted to use =straight.el=. I also used Borg for a
32few months, but decided to try =straight.el= which allows direct use
33of the various package archives.
34
35** Installation
36:PROPERTIES:
37:CUSTOM_ID: installation
38:END:
39
40To use this config for your Emacs, first you need to clone this repo,
41then tangle =init.org= into =init.el=, and optionally byte-compile
42=init.el=.
43
44First, clone the repository and =cd= into it:
45
46#+begin_src sh :tangle no
47git clone https://git.sr.ht/~bandali/dotfiles ~/.emacs.d
48cd ~/.emacs.d
49#+end_src
50
51Then, decide if you would like to use a byte-compiled init file, and
52set the [[#byte-compiled-init][a/byte-compiled-init]] variable accordingly.
53
54Now, first tangle =init.org=, and only if you chose to have a
55byte-compiled init, build init as well:
56
57#+begin_src sh :tangle no
58make tangle-init
59make build-init
60#+end_src
61
62If you'd like to use a byte-compiled init, it's important that it be
63recompiled whenever =init.el= is generated from an updated =init.org=.
64Not only does my setup automatically and asynchronously tangle
65=init.org= to =init.el= every time you edit and save =init.org= in GNU
66Emacs, 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
68about manually tangling and compiling your init file whenever you
69change it. The output of the last byte-compilation in the current
70session is kept in a =*compilation*= buffer, which will automatically
71be displayed if compilation fails.

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

144
145If you would like a byte-compiled init file, set the following
146variable 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.")

154
155** Emacs initialization
156
157I'd like to do a couple of measurements of Emacs' startup time. First,
158let'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
169Also, temporarily increase ~gc-cons-threshhold~ and
170~gc-cons-percentage~ during startup to reduce garbage collection
171frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
172startup 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
185Of course, we'd like to set them back to their defaults once we're
186done 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
197Increase the number of lines kept in message logs (the =*Messages*=
198buffer).
199
200#+begin_src emacs-lisp
201(setq message-log-max 20000)
202#+end_src
203
204Optionally, we could suppress some byte compiler warnings like below,
205but 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

214

217 user-mail-address "amin@bndl.org")
218#+end_src
219
220** Package management
221
222*** No =package.el=
223
224I can do all my package management things with =straight.el=, and
225don'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
232But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
233right now), and even when released it'll be long before most distros
234ship in their repos, I'll still put the old workaround with the
235commented 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
242Update: the above is not necessary, since =straight.el= automatically
243does that (and more). See =straight-package-neutering-mode=.
244
245*** =straight.el=

283
284(setq straight-use-package-by-default t)
285#+end_src
286
287Since we enable =straight.el='s =straight-use-package-by-default=
288integration, we will define a =use-feature= for plain ole
289=use-package= without any of the =straight.el= stuff.
290

586*** Time and battery in mode-line
587
588Enable displaying time and battery in the mode-line, since I'm not
589using the Xfce panel anymore. Also, I don't need to see the load
590average on a regular basis, so disable that.

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

652*** Startup screen and =*scratch*=
653
654Firstly, let Emacs know that I'd like to have =*scratch*= as my
655startup buffer.
656
657#+begin_src emacs-lisp
658(setq initial-buffer-choice t)
659#+end_src
660
661Now let's customize the =*scratch*= buffer a bit. First off, I don't
662need the default hint.

664#+begin_src emacs-lisp
665(setq initial-scratch-message nil)
666#+end_src
667
668Also, let's use Text mode as the major mode, in case I want to
669customize it (=*scratch*='s default major mode, Fundamental mode,
670can't really be customized).
671
672#+begin_src emacs-lisp
673(setq initial-major-mode 'text-mode)
674#+end_src
675
676Inhibit the buffer list when more than 2 files are loaded.

680#+end_src

704*** Backups
705
706Emacs' default backup settings aren't that great. Let's use more
