11This org file is my literate configuration for GNU Emacs, and is
3b98e899
AB
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

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.

37** Installation
38
4ae2cd62
AB
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
4b4e432d 43#+begin_src sh :tangle no
4ae2cd62
AB
44git clone https://github.com/aminb/dotfiles ~/.emacs.d
45cd ~/.emacs.d
46make bootstrap-borg

132** Emacs initialization
133
134I'd like to do a couple of measurements of Emacs' startup time. First,
135let's see how long Emacs takes to start up, before even loading
136=init.el=, i.e. =user-init-file=:
137
138#+begin_src emacs-lisp
850dd012 139(defvar amin--before-user-init-time (current-time)
180cab37
AB
140 "Value of `current-time' when Emacs begins loading `user-init-file'.")
141(message "Loading Emacs...done (%.3fs)"
850dd012 142 (float-time (time-subtract amin--before-user-init-time
180cab37
AB
143 before-init-time)))
144#+end_src
145
146Also, temporarily increase ~gc-cons-threshhold~ and
147~gc-cons-percentage~ during startup to reduce garbage collection
148frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
149startup time as well.
150
151#+begin_src emacs-lisp
850dd012
AB
152(defvar amin--gc-cons-threshold gc-cons-threshold)
153(defvar amin--gc-cons-percentage gc-cons-percentage)
154(defvar amin--file-name-handler-alist file-name-handler-alist)

158 ;; sidesteps a bug when profiling with esup

162Of course, we'd like to set them back to their defaults once we're
163done initializing.

181Optionally, we could suppress some byte compiler warnings like below,
182but for now I've decided to keep them enabled. See documentation for
183~byte-compile-warnings~ for more details.

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

223#+end_quote
224
225[[https://github.com/emacscollective/borg][Borg]] is at the heart of package management of my Emacs setup. In
226short, it creates a git submodule in =lib/= for each package, which
227can then be managed with the help of Magit or other tools.

352** Server
353
354Start server if not already running. Alternatively, can be done by
355issuing =emacs --daemon= in the terminal, which can be automated with
356a systemd service or using =brew services start emacs= on macOS. I use
357Emacs as my window manager (via EXWM), so I always start Emacs on
358login; so starting the server from inside Emacs is good enough for me.

536
537Firstly, let Emacs know that I'd like to have =*scratch*= as my
538startup buffer.
539
540#+begin_src emacs-lisp
541(setq initial-buffer-choice t)

544Now let's customize the =*scratch*= buffer a bit. First off, I don't

548(setq initial-scratch-message nil)
549#+end_src
550
551Also, let's use Text mode as the major mode, in case I want to
552customize it (=*scratch*='s default major mode, Fundamental mode,
553can't really be customized).
554
555#+begin_src emacs-lisp

559Inhibit the buffer list when more than 2 files are loaded.
