  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
  49 #+end_src

  79 that =init.el= is an auto-generated file, not supposed to be edited),
  80 and provides some convenient key bindings for browsing through the

 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.
 170
 171 #+begin_src emacs-lisp
 172 ;; (setq byte-compile-warnings
 173 ;;       '(not free-vars unresolved noruntime lexical make-local))
 174 #+end_src

 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

 223       (bootstrap-version 5))

 234 #+end_src
 235
 236 Since we enable =straight.el='s =straight-use-package-by-default=
 237 integration, we will define a =use-feature= for plain ole
 238 =use-package= without any of the =straight.el= stuff.
 239

 252 Assimilate Emacs packages as Git submodules
 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.

 519 ** Defaults
 520
 521 *** Time and battery in mode-line
 522
 523 Enable displaying time and battery in the mode-line, since I'm not
 524 using the Xfce panel anymore. Also, I don't need to see the load
 525 average on a regular basis, so disable that.
 526
 527 Note: using =i3status= on sway at the moment, so disabling this.

 544 EXWM. I'm fine with the default for now.

 551 *** Disable disabled commands
 552
 553 Emacs disables some commands by default that could persumably be
 554 confusing for novice users. Let's disable that.

 557 (setq disabled-command-function nil)
 558 #+end_src
 559
 560 *** Kill-ring
 561
 562 Save what I copy into clipboard from other applications into Emacs'
 563 kill-ring, which would allow me to still be able to easily access it
 564 in case I kill (cut or copy) something else inside Emacs before
 565 yanking (pasting) what I'd originally intended to.

 578 *** Lazy-person-friendly yes/no prompts
 579
 580 Lazy people would prefer to type fewer keystrokes, especially for yes
 581 or no questions. I'm lazy.

 587 *** Startup screen and =*scratch*=
 588
 589 Firstly, let Emacs know that I'd like to have =*scratch*= as my
 590 startup buffer.
 591
 592 #+begin_src emacs-lisp
 593 (setq initial-buffer-choice t)
 594 #+end_src
 595
 596 Now let's customize the =*scratch*= buffer a bit. First off, I don't
 597 need the default hint.
 598
 599 #+begin_src emacs-lisp
 600 (setq initial-scratch-message nil)
 601 #+end_src
 602
 603 Also, let's use Text mode as the major mode, in case I want to
 604 customize it (=*scratch*='s default major mode, Fundamental mode,
 605 can't really be customized).
 606
 607 #+begin_src emacs-lisp
 608 (setq initial-major-mode 'text-mode)
 609 #+end_src
 610
 611 Inhibit the buffer list when more than 2 files are loaded.
 612
 613 #+begin_src emacs-lisp
 614 (setq inhibit-startup-buffer-menu t)
 615 #+end_src
 616
 617 I don't really need to see the startup screen or echo area message
 618 either.
 619

 621 (advice-add #'display-startup-echo-area-message :override #'ignore)

 624 #+end_src
 625
 626 *** More useful frame titles
 627
 628 Show either the file name or the buffer name (in case the buffer isn't
 629 visiting a file). Borrowed from Emacs Prelude.
 630
 631 #+begin_src emacs-lisp
 632 (setq frame-title-format

 636                  "%b"))))
 637 #+end_src
 638
 639 *** Backups
 640
 641 Emacs' default backup settings aren't that great. Let's use more
 642 sensible options. See documentation for the ~make-backup-file~
 643 variable.
