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/emacscollective/borg][Borg]]. Over the years, I've taken inspiration from configurations of
14many different people. Some of the configurations that I can remember
15off 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 Borg. For what it's worth, I briefly
32experimented with [[https://github.com/raxod502/straight.el][straight.el]], but found that it added about 2 seconds
33to my init time; which is unacceptable for me: I use Emacs as my
34window manager (via EXWM) and coming from bspwm, I'm too used to
35having fast startup times.
36
37** Installation
38
39To use this config for your Emacs, first you need to clone this repo,
40then bootstrap Borg, tell Borg to retrieve package submodules, and
41byte-compiled the packages. Something along these lines should work:
42
43#+begin_src sh :tangle no
44git clone https://github.com/aminb/dotfiles ~/.emacs.d
45cd ~/.emacs.d
46make bootstrap-borg
47make bootstrap
48make build

118** Emacs initialization
119
120I'd like to do a couple of measurements of Emacs' startup time. First,
121let's see how long Emacs takes to start up, before even loading
122=init.el=, i.e. =user-init-file=:
123
124#+begin_src emacs-lisp
125(defvar a/before-user-init-time (current-time)
126 "Value of `current-time' when Emacs begins loading `user-init-file'.")
127(message "Loading Emacs...done (%.3fs)"
128 (float-time (time-subtract a/before-user-init-time
129 before-init-time)))
130#+end_src
131
132Also, temporarily increase ~gc-cons-threshhold~ and
133~gc-cons-percentage~ during startup to reduce garbage collection
134frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
135startup time as well.
136
137#+begin_src emacs-lisp
138(defvar a/gc-cons-threshold gc-cons-threshold)
139(defvar a/gc-cons-percentage gc-cons-percentage)
140(defvar a/file-name-handler-alist file-name-handler-alist)
141(setq gc-cons-threshold (* 400 1024 1024) ; 400 MiB
142 gc-cons-percentage 0.6
143 file-name-handler-alist nil
144 ;; sidesteps a bug when profiling with esup
145 esup-child-profile-require-level 0)
146#+end_src
147
148Of course, we'd like to set them back to their defaults once we're
149done initializing.
150
151#+begin_src emacs-lisp
152(add-hook
153 'after-init-hook
154 (lambda ()
155 (setq gc-cons-threshold a/gc-cons-threshold
156 gc-cons-percentage a/gc-cons-percentage
157 file-name-handler-alist a/file-name-handler-alist)))
158#+end_src

160Increase the number of lines kept in message logs (the =*Messages*=
161buffer).
162
163#+begin_src emacs-lisp
164(setq message-log-max 20000)
165#+end_src
166
167Optionally, we could suppress some byte compiler warnings like below,
168but for now I've decided to keep them enabled. See documentation for
169~byte-compile-warnings~ for more details.

183** Package management
184
185*** No =package.el=
186
187I can do all my package management things with =straight.el=, and
188don't need Emacs' built-in =package.el=. Emacs 27 lets us disable
189=package.el= in the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
190
191#+begin_src emacs-lisp :tangle early-init.el
192(setq package-enable-at-startup nil)
193#+end_src
194
195But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
196right now), and even when released it'll be long before most distros
197ship in their repos, I'll still put the old workaround with the
198commented call to ~package-initialize~ here anyway.
199
200#+begin_src emacs-lisp :tangle no
201(setq package-enable-at-startup nil)
202;; (package-initialize)
203#+end_src
204
205Update: the above is not necessary, since =straight.el= automatically
206does that (and more). See =straight-package-neutering-mode=.
207

255[[https://github.com/emacscollective/borg][Borg]] is at the heart of package management of my Emacs setup. In

587*** Startup screen and =*scratch*=
588
589Firstly, let Emacs know that I'd like to have =*scratch*= as my
590startup buffer.
591
592#+begin_src emacs-lisp
593(setq initial-buffer-choice t)
594#+end_src
595
596Now let's customize the =*scratch*= buffer a bit. First off, I don't
597need the default hint.
598
599#+begin_src emacs-lisp
600(setq initial-scratch-message nil)
601#+end_src
602
603Also, let's use Text mode as the major mode, in case I want to
604customize it (=*scratch*='s default major mode, Fundamental mode,
605can't really be customized).
606
607#+begin_src emacs-lisp
608(setq initial-major-mode 'text-mode)
609#+end_src
610
611Inhibit the buffer list when more than 2 files are loaded.
612
613#+begin_src emacs-lisp
614(setq inhibit-startup-buffer-menu t)
615#+end_src
616
617I don't really need to see the startup screen or echo area message
618either.
