11This org file is my literate configuration for GNU Emacs, and is
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
25- [[https://github.com/wasamasa/dotemacs][wasamasa/dotemacs]]
26- [[https://github.com/hlissner/doom-emacs][Doom Emacs]]
27
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.
36
37** Installation
38
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
43#+begin_src sh :tangle no
44git clone https://github.com/aminb/dotfiles ~/.emacs.d
45cd ~/.emacs.d
46make bootstrap-borg
47make bootstrap
48make build

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
139(defvar amin--before-user-init-time (current-time)
140 "Value of `current-time' when Emacs begins loading `user-init-file'.")
141(message "Loading Emacs...done (%.3fs)"
142 (float-time (time-subtract amin--before-user-init-time
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
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)
155(setq gc-cons-threshold (* 400 1024 1024) ; 400 MiB
156 gc-cons-percentage 0.6
157 file-name-handler-alist nil
158 ;; sidesteps a bug when profiling with esup
159 esup-child-profile-require-level 0)
160#+end_src
161
162Of course, we'd like to set them back to their defaults once we're
163done initializing.
164
165#+begin_src emacs-lisp
166(add-hook
167 'after-init-hook
168 (lambda ()
169 (setq gc-cons-threshold amin--gc-cons-threshold
170 gc-cons-percentage amin--gc-cons-percentage
171 file-name-handler-alist amin--file-name-handler-alist)))
172#+end_src
173
174Increase the number of lines kept in message logs (the =*Messages*=
175buffer).
176
177#+begin_src emacs-lisp
178(setq message-log-max 20000)
179#+end_src
180
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.
184
185#+begin_src emacs-lisp

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.
213
214#+begin_src emacs-lisp
215(setq package-enable-at-startup nil)
216;; (package-initialize)

221#+begin_quote

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.
228

253#+end_quote
254
255[[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
256packages (in our case especially the latter) in a neatly organized way
257and without compromising on performance.

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

291
292#+begin_quote

294#+end_quote
295
296By default, even for Emacs' built-in packages, the configuration files
297and persistent data are all over the place. Use =no-littering= to help
298contain the mess.
299
300#+begin_src emacs-lisp

309#+end_src
310
311** Custom file (=custom.el=)
312
313I'm not planning on using the custom file much, but even so, I
314definitely don't want it mixing with =init.el=. So, here; let's give
315it it's own file. While at it, treat themes as safe.
316
317#+begin_src emacs-lisp
318(use-package custom

325#+end_src
326
327** Better =$PATH= handling
328
329Let's use [[https://github.com/purcell/exec-path-from-shell][exec-path-from-shell]] to make Emacs use the =$PATH= as set up
330in my shell.
331
332#+begin_src emacs-lisp

350#+end_src
351
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.

493*** Kill-ring
494
495Save what I copy into clipboard from other applications into Emacs'

536Also, let's use Text mode as the major mode, in case I want to
537customize it (=*scratch*='s default major mode, Fundamental mode,
538can't really be customized).
539
540#+begin_src emacs-lisp

544Inhibit the buffer list when more than 2 files are loaded.
