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/raxod502/straight.el][straight.el]]. Over the years, I've taken inspiration from
14 configurations of many different people. Some of the configurations
15 that I can remember off 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
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 =straight.el=. I also used Borg for a
32 few months, but decided to try =straight.el= which allows direct use
33 of the various package archives.

62 Enable =view-mode=, which both makes the file read-only (as a reminder
63 that =init.el= is an auto-generated file, not supposed to be edited),
64 and provides some convenient key bindings for browsing through the

102 ** Emacs initialization
103
104 I'd like to do a couple of measurements of Emacs' startup time. First,
105 let's see how long Emacs takes to start up, before even loading
106 =init.el=, i.e. =user-init-file=:
107
108 #+begin_src emacs-lisp
109 (defvar a/before-user-init-time (current-time)
110 "Value of `current-time' when Emacs begins loading `user-init-file'.")
111 (message "Loading Emacs...done (%.3fs)"
112 (float-time (time-subtract a/before-user-init-time
113 before-init-time)))
114 #+end_src
115
116 Also, temporarily increase ~gc-cons-threshhold~ and
117 ~gc-cons-percentage~ during startup to reduce garbage collection
118 frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
119 startup time as well.
120
121 #+begin_src emacs-lisp
122 (defvar a/gc-cons-threshold gc-cons-threshold)
123 (defvar a/gc-cons-percentage gc-cons-percentage)
124 (defvar a/file-name-handler-alist file-name-handler-alist)
125 (setq gc-cons-threshold (* 400 1024 1024) ; 400 MiB
126 gc-cons-percentage 0.6
127 file-name-handler-alist nil
128 ;; sidesteps a bug when profiling with esup
129 esup-child-profile-require-level 0)
130 #+end_src
131
132 Of course, we'd like to set them back to their defaults once we're
133 done initializing.
134
135 #+begin_src emacs-lisp
136 (add-hook
137 'after-init-hook
138 (lambda ()
139 (setq gc-cons-threshold a/gc-cons-threshold
140 gc-cons-percentage a/gc-cons-percentage
141 file-name-handler-alist a/file-name-handler-alist)))
142 #+end_src
143
144 Increase the number of lines kept in message logs (the =*Messages*=
145 buffer).
146
147 #+begin_src emacs-lisp
148 (setq message-log-max 20000)
149 #+end_src
150
151 Optionally, we could suppress some byte compiler warnings like below,
152 but for now I've decided to keep them enabled. See documentation for
153 ~byte-compile-warnings~ for more details.
154
155 #+begin_src emacs-lisp

167 ** Package management
168
169 *** No =package.el=
170
171 I can do all my package management things with =straight.el=, and
172 don't need Emacs' built-in =package.el=. Emacs 27 lets us disable
173 =package.el= in the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
174
175 #+begin_src emacs-lisp :tangle early-init.el
176 (setq package-enable-at-startup nil)
177 #+end_src
178
179 But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
180 right now), and even when released it'll be long before most distros
181 ship in their repos, I'll still put the old workaround with the
182 commented call to ~package-initialize~ here anyway.
183
184 #+begin_src emacs-lisp :tangle no
185 (setq package-enable-at-startup nil)
186 ;; (package-initialize)
187 #+end_src
188
189 Update: the above is not necessary, since =straight.el= automatically
190 does that (and more). See =straight-package-neutering-mode=.
191
192 *** =straight.el=

233 Since we enable =straight.el='s =straight-use-package-by-default=
234 integration, we will define a =use-feature= for plain ole
235 =use-package= without any of the =straight.el= stuff.

252 [[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring

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

300 By default, even for Emacs' built-in packages, the configuration files

302 contain the mess.

315 ** Custom file (=custom.el=)
316
317 I'm not planning on using the custom file much, but even so, I
318 definitely don't want it mixing with =init.el=. So, here; let's give
319 it it's own file. While at it, treat themes as safe.
320

365 ** Server
366
367 Start server if not already running. Alternatively, can be done by
368 issuing =emacs --daemon= in the terminal, which can be automated with
369 a systemd service or using =brew services start emacs= on macOS. I use
370 Emacs as my window manager (via EXWM), so I always start Emacs on
371 login; so starting the server from inside Emacs is good enough for me.

527 *** Kill-ring
528
529 Save what I copy into clipboard from other applications into Emacs'

570 Also, let's use Text mode as the major mode, in case I want to
