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

115 :CUSTOM_ID: initial-setup
118 ** Emacs initialization
120 I'd like to do a couple of measurements of Emacs' startup time. First,
121 let's see how long Emacs takes to start up, before even loading
122 =init.el=, i.e. =user-init-file=:
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
132 Also, temporarily increase ~gc-cons-threshhold~ and
133 ~gc-cons-percentage~ during startup to reduce garbage collection
134 frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
135 startup time as well.
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)
148 Of course, we'd like to set them back to their defaults once we're
151 #+begin_src emacs-lisp
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)))
160 Increase the number of lines kept in message logs (the =*Messages*=
163 #+begin_src emacs-lisp
164 (setq message-log-max 20000)
167 Optionally, we could suppress some byte compiler warnings like below,
168 but for now I've decided to keep them enabled. See documentation for
169 ~byte-compile-warnings~ for more details.
171 #+begin_src emacs-lisp
172 ;; (setq byte-compile-warnings
173 ;; '(not free-vars unresolved noruntime lexical make-local))
178 #+begin_src emacs-lisp
179 (setq user-full-name "Amin Bandali"
180 user-mail-address "amin@aminb.org")
183 ** Package management
187 I can do all my package management things with Borg, and don't need
188 Emacs' built-in =package.el=. Emacs 27 lets us disable =package.el= in
189 the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
191 #+begin_src emacs-lisp :tangle early-init.el
192 (setq package-enable-at-startup nil)
195 But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
196 right now), and even when released it'll be long before most distros
197 ship in their repos, I'll still put the old workaround with the
198 commented call to ~package-initialize~ here anyway.
200 #+begin_src emacs-lisp
201 (setq package-enable-at-startup nil)
202 ;; (package-initialize)
208 Assimilate Emacs packages as Git submodules
211 [[https://github.com/emacscollective/borg][Borg]] is at the heart of package management of my Emacs setup. In
212 short, it creates a git submodule in =lib/= for each package, which
213 can then be managed with the help of Magit or other tools.
215 #+begin_src emacs-lisp
216 (setq user-init-file (or load-file-name buffer-file-name)
217 user-emacs-directory (file-name-directory user-init-file))

231 ("C-c b b" . borg-build)
232 ("C-c b c" . borg-clone)
233 ("C-c b r" . borg-remove)))
239 A use-package declaration for simplifying your .emacs
242 [[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
243 packages (in our case especially the latter) in a neatly organized way
244 and without compromising on performance.

253 (setq use-package-verbose nil
254 use-package-expand-minimally t))
260 Browse the Emacsmirror package database
263 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
264 database, low-level functions for querying the database, and a
265 =package.el=-like user interface for browsing the available packages.
267 #+begin_src emacs-lisp
271 (("C-c b d" . epkg-describe-package)

281 ** No littering in =~/.emacs.d=
284 Help keeping ~/.emacs.d clean
287 By default, even for Emacs' built-in packages, the configuration files
288 and persistent data are all over the place. Use =no-littering= to help

302 ** Custom file (=custom.el=)
304 I'm not planning on using the custom file much, but even so, I
305 definitely don't want it mixing with =init.el=. So, here; let's give
306 it it's own file. While at it, treat themes as safe.
308 #+begin_src emacs-lisp
312 (setq custom-file (no-littering-expand-etc-file-name "custom.el"))

320 Load the secrets file if it exists, otherwise show a warning.
322 #+begin_src emacs-lisp
324 (load (no-littering-expand-etc-file-name "secrets")))
327 ** Better =$PATH= handling
329 Let's use [[https://github.com/purcell/exec-path-from-shell][exec-path-from-shell]] to make Emacs use the =$PATH= as set up
332 #+begin_src emacs-lisp
333 (use-package exec-path-from-shell
336 (setq exec-path-from-shell-check-startup-files nil)

340 (exec-path-from-shell-copy-env "SSH_AGENT_PID")
341 (exec-path-from-shell-copy-env "SSH_AUTH_SOCK"))
344 ** COMMENT Only one custom theme at a time
346 #+begin_src emacs-lisp

348 "Clear existing theme settings instead of layering them"

354 Start server if not already running. Alternatively, can be done by
355 issuing =emacs --daemon= in the terminal, which can be automated with
356 a systemd service or using =brew services start emacs= on macOS. I use
357 Emacs as my window manager (via EXWM), so I always start Emacs on
358 login; so starting the server from inside Emacs is good enough for me.
360 See [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Emacs-Server.html#Emacs-Server][Using Emacs as a Server]].

422 buffers and/or modes.

475 *** Time and battery in mode-line
477 Enable displaying time and battery in the mode-line, since I'm not
478 using the Xfce panel anymore. Also, I don't need to see the load
479 average on a regular basis, so disable that.
481 Note: using =i3status= on sway at the moment, so disabling this.

508 confusing for novice users. Let's disable that.

516 Save what I copy into clipboard from other applications into Emacs'
517 kill-ring, which would allow me to still be able to easily access it

551 need the default hint.

557 Also, let's use Text mode as the major mode, in case I want to
558 customize it (=*scratch*='s default major mode, Fundamental mode,
559 can't really be customized).
