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

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

142** Emacs initialization
143
144I'd like to do a couple of measurements of Emacs' startup time. First,
145let'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
156Also, temporarily increase ~gc-cons-threshhold~ and
157~gc-cons-percentage~ during startup to reduce garbage collection
158frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
159startup 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
172Of course, we'd like to set them back to their defaults once we're
173done 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
184Increase the number of lines kept in message logs (the =*Messages*=
185buffer).
186
187#+begin_src emacs-lisp
188(setq message-log-max 20000)
189#+end_src
190
191Optionally, we could suppress some byte compiler warnings like below,
192but for now I've decided to keep them enabled. See documentation for
193~byte-compile-warnings~ for more details.
194

207** Package management
208
209*** No =package.el=
210
211I can do all my package management things with =straight.el=, and
212don'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
219But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
220right now), and even when released it'll be long before most distros
221ship in their repos, I'll still put the old workaround with the
222commented 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
229Update: the above is not necessary, since =straight.el= automatically
230does that (and more). See =straight-package-neutering-mode=.

414Emacs as my window manager (via EXWM), so I always start Emacs on

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

624#+begin_src emacs-lisp
625(setq inhibit-startup-buffer-menu t)
626#+end_src
627
628I don't really need to see the startup screen or echo area message
629either.
