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:
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 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.
36
37 ** Installation
38
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:
42
43 #+begin_src sh :tangle no
44 git clone https://github.com/aminb/dotfiles ~/.emacs.d
45 cd ~/.emacs.d
46 make bootstrap-borg
47 make bootstrap
48 make build

118 ** Emacs initialization
119
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=:
123
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
129 before-init-time)))
130 #+end_src
131
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.
136
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)
146 #+end_src
147
148 Of course, we'd like to set them back to their defaults once we're
149 done initializing.
150
151 #+begin_src emacs-lisp
152 (add-hook
153 'after-init-hook
154 (lambda ()
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)))
158 #+end_src
159
160 Increase the number of lines kept in message logs (the =*Messages*=
161 buffer).
162
163 #+begin_src emacs-lisp
164 (setq message-log-max 20000)
165 #+end_src
166
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.

181 #+end_src
182
183 ** Package management
184
185 *** No =package.el=
186
187 I can do all my package management things with =straight.el=, and
188 don't need Emacs' built-in =package.el=. Emacs 27 lets us disable
189 =package.el= in the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
190
191 #+begin_src emacs-lisp :tangle early-init.el
192 (setq package-enable-at-startup nil)
193 #+end_src
194
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.
199
200 #+begin_src emacs-lisp :tangle no
201 (setq package-enable-at-startup nil)
202 ;; (package-initialize)
203 #+end_src
204
205 Update: the above is not necessary, since =straight.el= automatically
206 does that (and more). See =straight-package-neutering-mode=.
207
208 *** =straight.el=
209
210 #+begin_quote
211 Next-generation, purely functional package manager for the Emacs
212 hacker.
213 #+end_quote

253 #+end_quote
254
255 [[https://github.com/emacscollective/borg][Borg]] is at the heart of package management of my Emacs setup. In
256 short, it creates a git submodule in =lib/= for each package, which
257 can then be managed with the help of Magit or other tools.

585 *** Startup screen and =*scratch*=
586
587 Firstly, let Emacs know that I'd like to have =*scratch*= as my
588 startup buffer.
589
590 #+begin_src emacs-lisp
591 (setq initial-buffer-choice t)
592 #+end_src
593
594 Now let's customize the =*scratch*= buffer a bit. First off, I don't
595 need the default hint.
596
597 #+begin_src emacs-lisp
598 (setq initial-scratch-message nil)
599 #+end_src
600
601 Also, let's use Text mode as the major mode, in case I want to
602 customize it (=*scratch*='s default major mode, Fundamental mode,
603 can't really be customized).
604
605 #+begin_src emacs-lisp
606 (setq initial-major-mode 'text-mode)
607 #+end_src
608
609 Inhibit the buffer list when more than 2 files are loaded.
610
611 #+begin_src emacs-lisp
612 (setq inhibit-startup-buffer-menu t)
613 #+end_src
614
615 I don't really need to see the startup screen or echo area message
616 either.

624 *** More useful frame titles

781 First, we have to resort to a [[https://github.com/raxod502/straight.el#installing-org-with-straightel][hack]] to be able to use the correct
