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

79that =init.el= is an auto-generated file, not supposed to be edited),

134** Emacs initialization
135
136I'd like to do a couple of measurements of Emacs' startup time. First,
137let's see how long Emacs takes to start up, before even loading
138=init.el=, i.e. =user-init-file=:
139
140#+begin_src emacs-lisp
141(defvar amin--before-user-init-time (current-time)
142 "Value of `current-time' when Emacs begins loading `user-init-file'.")
143(message "Loading Emacs...done (%.3fs)"
144 (float-time (time-subtract amin--before-user-init-time
145 before-init-time)))
146#+end_src
147
148Also, temporarily increase ~gc-cons-threshhold~ and
149~gc-cons-percentage~ during startup to reduce garbage collection
150frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
151startup time as well.
152
153#+begin_src emacs-lisp
154(defvar amin--gc-cons-threshold gc-cons-threshold)
155(defvar amin--gc-cons-percentage gc-cons-percentage)
156(defvar amin--file-name-handler-alist file-name-handler-alist)
157(setq gc-cons-threshold (* 400 1024 1024) ; 400 MiB
158 gc-cons-percentage 0.6
159 file-name-handler-alist nil
160 ;; sidesteps a bug when profiling with esup
161 esup-child-profile-require-level 0)
162#+end_src
163
164Of course, we'd like to set them back to their defaults once we're
165done initializing.
166
167#+begin_src emacs-lisp
168(add-hook
169 'after-init-hook
170 (lambda ()
171 (setq gc-cons-threshold amin--gc-cons-threshold
172 gc-cons-percentage amin--gc-cons-percentage
173 file-name-handler-alist amin--file-name-handler-alist)))
174#+end_src
175
176Increase the number of lines kept in message logs (the =*Messages*=
177buffer).
178
179#+begin_src emacs-lisp
180(setq message-log-max 20000)
181#+end_src
182
183Optionally, we could suppress some byte compiler warnings like below,
184but for now I've decided to keep them enabled. See documentation for
185~byte-compile-warnings~ for more details.
186
187#+begin_src emacs-lisp

198
199** Package management
200
201*** No =package.el=
202
203I can do all my package management things with Borg, and don't need
204Emacs' built-in =package.el=. Emacs 27 lets us disable =package.el= in
205the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
206
207#+begin_src emacs-lisp :tangle early-init.el
208(setq package-enable-at-startup nil)
209#+end_src
210
211But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
212right now), and even when released it'll be long before most distros
213ship in their repos, I'll still put the old workaround with the
214commented call to ~package-initialize~ here anyway.
215
216#+begin_src emacs-lisp
217(setq package-enable-at-startup nil)
218;; (package-initialize)

225#+end_quote
226
227[[https://github.com/emacscollective/borg][Borg]] is at the heart of package management of my Emacs setup. In
228short, it creates a git submodule in =lib/= for each package, which
229can then be managed with the help of Magit or other tools.

257
258[[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
259packages (in our case especially the latter) in a neatly organized way
260and without compromising on performance.

279Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
280database, low-level functions for querying the database, and a
281=package.el=-like user interface for browsing the available packages.

298By default, even for Emacs' built-in packages, the configuration files
299and persistent data are all over the place. Use =no-littering= to help
300contain the mess.

315I'm not planning on using the custom file much, but even so, I
316definitely don't want it mixing with =init.el=. So, here; let's give
317it it's own file. While at it, treat themes as safe.

368Emacs as my window manager (via EXWM), so I always start Emacs on
369login; so starting the server from inside Emacs is good enough for me.

556*** Lazy-person-friendly yes/no prompts
557
558Lazy people would prefer to type fewer keystrokes, especially for yes
559or no questions. I'm lazy.

565*** Startup screen and =*scratch*=
566
567Firstly, let Emacs know that I'd like to have =*scratch*= as my
568startup buffer.
569
570#+begin_src emacs-lisp
571(setq initial-buffer-choice t)
572#+end_src
573
574Now let's customize the =*scratch*= buffer a bit. First off, I don't
575need the default hint.
576
577#+begin_src emacs-lisp
578(setq initial-scratch-message nil)
579#+end_src
580
581Also, let's use Text mode as the major mode, in case I want to
582customize it (=*scratch*='s default major mode, Fundamental mode,
583can't really be customized).
584
585#+begin_src emacs-lisp
586(setq initial-major-mode 'text-mode)
587#+end_src
588
589Inhibit the buffer list when more than 2 files are loaded.
590
591#+begin_src emacs-lisp
592(setq inhibit-startup-buffer-menu t)
593#+end_src
594
595I don't really need to see the startup screen or echo area message
596either.

604*** More useful frame titles

2234Manually install bbdb (=lisp/bbdb= copied from an ELPA-based setup),
2235because installing it from source on Emacs 27 using the following
2236submodule configuration for some reason doesn’t work and results in
2237very strange errors when using any of the functions.
