1 #+title: =aminb='s Literate Emacs Configuration
4 #+property: header-args :tangle yes
11 This org file is my literate configuration for GNU Emacs, and is
12 tangled 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
14 many different people. Some of the configurations that I can remember
15 off the top of my head are:
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
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]]
28 I'd like to have a fully reproducible Emacs setup (part of the reason
29 why I store my configuration in this repository) but unfortunately out
30 of the box, that's not achievable with =package.el=, not currently
31 anyway. So, I've opted to use Borg. For what it's worth, I briefly
32 experimented with [[https://github.com/raxod502/straight.el][straight.el]], but found that it added about 2 seconds
33 to my init time; which is unacceptable for me: I use Emacs as my
34 window manager (via EXWM) and coming from bspwm, I'm too used to
35 having fast startup times.
39 To use this config for your Emacs, first you need to clone this repo,
40 then bootstrap Borg, tell Borg to retrieve package submodules, and
41 byte-compiled the packages. Something along these lines should work:
43 #+begin_src sh :tangle no
44 git clone https://github.com/aminb/dotfiles ~/.emacs.d

106 ** Naming conventions
108 The conventions below were inspired by [[https://github.com/hlissner/doom-emacs][Doom]]'s conventions, found
109 [[https://github.com/hlissner/doom-emacs/blob/5dacbb7cb1c6ac246a9ccd15e6c4290def67757c/core/core.el#L3-L17][here]]. Naturally, I use my initials, =ab=, instead of =doom=.

133 ** Emacs initialization
135 I'd like to do a couple of measurements of Emacs' startup time. First,
136 let's see how long Emacs takes to start up, before even loading
137 =init.el=, i.e. =user-init-file=:
139 #+begin_src emacs-lisp
140 (defvar ab--before-user-init-time (current-time)
141 "Value of `current-time' when Emacs begins loading `user-init-file'.")
142 (message "Loading Emacs...done (%.3fs)"
143 (float-time (time-subtract ab--before-user-init-time
147 Also, temporarily increase ~gc-cons-threshhold~ and
148 ~gc-cons-percentage~ during startup to reduce garbage collection
149 frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
150 startup time as well.
152 #+begin_src emacs-lisp
153 (defvar ab--gc-cons-threshold gc-cons-threshold)
154 (defvar ab--gc-cons-percentage gc-cons-percentage)
155 (defvar ab--file-name-handler-alist file-name-handler-alist)
156 (setq gc-cons-threshold (* 400 1024 1024) ; 400 MiB
157 gc-cons-percentage 0.6
158 file-name-handler-alist nil
159 ;; sidesteps a bug when profiling with esup
160 esup-child-profile-require-level 0)
163 Of course, we'd like to set them back to their defaults once we're
166 #+begin_src emacs-lisp
170 (setq gc-cons-threshold ab--gc-cons-threshold
171 gc-cons-percentage ab--gc-cons-percentage
172 file-name-handler-alist ab--file-name-handler-alist)))
175 Increase the number of lines kept in message logs (the =*Messages*=
178 #+begin_src emacs-lisp
179 (setq message-log-max 20000)
182 Optionally, we could suppress some byte compiler warnings like below,
183 but for now I've decided to keep them enabled. See documentation for
184 ~byte-compile-warnings~ for more details.
186 #+begin_src emacs-lisp
187 ;; (setq byte-compile-warnings
188 ;; '(not free-vars unresolved noruntime lexical make-local))
191 ** Package management
195 I can do all my package management things with Borg, and don't need
196 Emacs' built-in =package.el=. Emacs 27 lets us disable =package.el= in
197 the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
199 #+begin_src emacs-lisp :tangle early-init.el
200 (setq package-enable-at-startup nil)
203 But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
204 right now), and even when released it'll be long before most distros
205 ship in their repos, I'll still put the old workaround with the
206 commented call to ~package-initialize~ here anyway.
208 #+begin_src emacs-lisp
209 (setq package-enable-at-startup nil)
210 ;; (package-initialize)
216 Assimilate Emacs packages as Git submodules
219 [[https://github.com/emacscollective/borg][Borg]] is at the heart of package management of my Emacs setup. In
220 short, it creates a git submodule in =lib/= for each package, which
221 can then be managed with the help of Magit or other tools.
223 #+begin_src emacs-lisp
224 (setq user-init-file (or load-file-name buffer-file-name)
225 user-emacs-directory (file-name-directory user-init-file))
226 (add-to-list 'load-path
227 (expand-file-name "lib/borg" user-emacs-directory))
235 A use-package declaration for simplifying your .emacs
238 [[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
239 packages (in our case especially the latter) in a neatly organized way
240 and without compromising on performance.
242 #+begin_src emacs-lisp
243 (require 'use-package)

249 (setq use-package-verbose nil

256 Browse the Emacsmirror package database
259 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
260 database, low-level functions for querying the database, and a
261 =package.el=-like user interface for browsing the available packages.
263 #+begin_src emacs-lisp
268 ** No littering in =~/.emacs.d=
271 Help keeping ~/.emacs.d clean
274 By default, even for Emacs' built-in packages, the configuration files
275 and persistent data are all over the place. Use =no-littering= to help

286 `((".*" ,(no-littering-expand-var-file-name "auto-save/") t))))
289 ** Custom file (=custom.el=)
291 I'm not planning on using the custom file much, but even so, I
292 definitely don't want it mixing with =init.el=. So, here; let's give
293 it it's own file. While at it, treat themes as safe.
295 #+begin_src emacs-lisp
299 (setq custom-file (no-littering-expand-etc-file-name "custom.el"))
300 (when (file-exists-p custom-file)
302 (setf custom-safe-themes t))
305 ** Better =$PATH= handling
307 Let's use [[https://github.com/purcell/exec-path-from-shell][exec-path-from-shell]] to make Emacs use the =$PATH= as set up
310 #+begin_src emacs-lisp
311 (use-package exec-path-from-shell

322 ** Only one custom theme at a time

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

508 need the default hint.

511 (setq initial-scratch-message nil)
514 Also, let's use Text mode as the major mode, in case I want to
515 customize it (=*scratch*='s default major mode, Fundamental mode,
516 can't really be customized).
