  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.
  34
  35 ** Installation
  36
  37 To use this config for your Emacs, first you need to clone this repo,
  38 then tangle =init.org= into =init.el=, and optionally byte-compile
  39 =init.el=.
  40
  41 First, clone the repository and =cd= into it:
  42
  43 #+begin_src sh :tangle no
  44 git clone https://git.sr.ht/~bandali/dotfiles ~/.emacs.d
  45 cd ~/.emacs.d
  46 #+end_src
  47
  48 Then, decide if you would like to use a byte-compiled init file, and
  49 set the following variable accordingly:
  50
  51 #+begin_src emacs-lisp
  52 (defvar a/byte-compiled-init t
  53   "If non-nil, byte-(re)compile init.el on successful tangles.")
  54 #+end_src
  55
  56 Now, first tangle =init.org=, and only if you chose to have a
  57 byte-compiled init, build init as well:
  58
  59 #+begin_src sh :tangle no
  60 make tangle-init
  61 make build-init
  62 #+end_src
  63
  64 If you'd like to use a byte-compiled init, it's important that it be
  65 recompiled whenever =init.el= is generated from an updated =init.org=.
  66 Not only does my setup automatically and asynchronously tangle
  67 =init.org= to =init.el= every time you edit and save =init.org= in GNU
  68 Emacs, it will also invoke =make build-init= if you set
  69 =a/byte-compiled-init= to =t= above, so you wouldn't have to worry
  70 about manually tangling and compiling your init file whenever you
  71 change it.  The output of the last byte-compilation in the current
  72 session is kept in a =*compilation*= buffer, which will automatically
  73 be displayed if compilation fails.

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

 142 ** Emacs initialization
 143
 144 I'd like to do a couple of measurements of Emacs' startup time. First,
 145 let's see how long Emacs takes to start up, before even loading
 146 =init.el=, i.e. =user-init-file=:
 147
 148 #+begin_src emacs-lisp
 149 (defvar a/before-user-init-time (current-time)
 150   "Value of `current-time' when Emacs begins loading `user-init-file'.")
 151 (message "Loading Emacs...done (%.3fs)"
 152          (float-time (time-subtract a/before-user-init-time
 153                                     before-init-time)))
 154 #+end_src
 155
 156 Also, temporarily increase ~gc-cons-threshhold~ and
 157 ~gc-cons-percentage~ during startup to reduce garbage collection
 158 frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
 159 startup time as well.
 160
 161 #+begin_src emacs-lisp
 162 (defvar a/gc-cons-threshold gc-cons-threshold)
 163 (defvar a/gc-cons-percentage gc-cons-percentage)
 164 (defvar a/file-name-handler-alist file-name-handler-alist)
 165 (setq gc-cons-threshold (* 400 1024 1024)  ; 400 MiB
 166       gc-cons-percentage 0.6
 167       file-name-handler-alist nil
 168       ;; sidesteps a bug when profiling with esup
 169       esup-child-profile-require-level 0)
 170 #+end_src
 171
 172 Of course, we'd like to set them back to their defaults once we're
 173 done initializing.
 174
 175 #+begin_src emacs-lisp
 176 (add-hook
 177  'after-init-hook
 178  (lambda ()
 179    (setq gc-cons-threshold a/gc-cons-threshold
 180          gc-cons-percentage a/gc-cons-percentage
 181          file-name-handler-alist a/file-name-handler-alist)))
 182 #+end_src
 183
 184 Increase the number of lines kept in message logs (the =*Messages*=
 185 buffer).
 186
 187 #+begin_src emacs-lisp
 188 (setq message-log-max 20000)
 189 #+end_src
 190
 191 Optionally, we could suppress some byte compiler warnings like below,
 192 but for now I've decided to keep them enabled. See documentation for
 193 ~byte-compile-warnings~ for more details.
 194
 195 #+begin_src emacs-lisp
 196 ;; (setq byte-compile-warnings
 197 ;;       '(not free-vars unresolved noruntime lexical make-local))
 198 #+end_src
 199
 200 ** whoami
 201
 202 #+begin_src emacs-lisp

 204       user-mail-address "amin@aminb.org")
 205 #+end_src
 206
 207 ** Package management
 208
 209 *** No =package.el=
 210
 211 I can do all my package management things with =straight.el=, and
 212 don't need Emacs' built-in =package.el=.  Emacs 27 lets us disable
 213 =package.el= in the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
 214
 215 #+begin_src emacs-lisp :tangle early-init.el
 216 (setq package-enable-at-startup nil)
 217 #+end_src
 218
 219 But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
 220 right now), and even when released it'll be long before most distros
 221 ship in their repos, I'll still put the old workaround with the
 222 commented call to ~package-initialize~ here anyway.
 223
 224 #+begin_src emacs-lisp :tangle no
 225 (setq package-enable-at-startup nil)
 226 ;; (package-initialize)
 227 #+end_src
 228
 229 Update: the above is not necessary, since =straight.el= automatically
 230 does that (and more).  See =straight-package-neutering-mode=.
 231
 232 *** =straight.el=

 274 Since we enable =straight.el='s =straight-use-package-by-default=
 275 integration, we will define a =use-feature= for plain ole
 276 =use-package= without any of the =straight.el= stuff.
 277

 358 ** Custom file (=custom.el=)
 359
 360 I'm not planning on using the custom file much, but even so, I
 361 definitely don't want it mixing with =init.el=. So, here; let's give
 362 it it's own file. While at it, treat themes as safe.

 409 ** Server
 410
 411 Start server if not already running. Alternatively, can be done by
 412 issuing =emacs --daemon= in the terminal, which can be automated with
 413 a systemd service or using =brew services start emacs= on macOS. I use
 414 Emacs as my window manager (via EXWM), so I always start Emacs on
 415 login; so starting the server from inside Emacs is good enough for me.

 532 *** Time and battery in mode-line
 533
 534 Enable displaying time and battery in the mode-line, since I'm not
 535 using the Xfce panel anymore. Also, I don't need to see the load
 536 average on a regular basis, so disable that.
 537
 538 Note: using =i3status= on sway at the moment, so disabling this.

 552 *** Smaller fringe
 553
 554 Might want to set the fringe to a smaller value, especially if using
 555 EXWM. I'm fine with the default for now.

 558 ;; (fringe-mode '(3 . 1))
 559 (fringe-mode nil)
 560 #+end_src
 561
 562 *** Disable disabled commands
 563
 564 Emacs disables some commands by default that could persumably be
 565 confusing for novice users. Let's disable that.
 566
 567 #+begin_src emacs-lisp
 568 (setq disabled-command-function nil)
 569 #+end_src
 570
 571 *** Kill-ring
 572
 573 Save what I copy into clipboard from other applications into Emacs'
 574 kill-ring, which would allow me to still be able to easily access it
 575 in case I kill (cut or copy) something else inside Emacs before
 576 yanking (pasting) what I'd originally intended to.

 586       resize-mini-windows t)

 588
 589 *** Lazy-person-friendly yes/no prompts
 590
 591 Lazy people would prefer to type fewer keystrokes, especially for yes
 592 or no questions. I'm lazy.
 593

 595 (defalias 'yes-or-no-p #'y-or-n-p)
 596 #+end_src
 597
 598 *** Startup screen and =*scratch*=
 599
 600 Firstly, let Emacs know that I'd like to have =*scratch*= as my
 601 startup buffer.
 602
 603 #+begin_src emacs-lisp
 604 (setq initial-buffer-choice t)
 605 #+end_src
 606
 607 Now let's customize the =*scratch*= buffer a bit. First off, I don't
 608 need the default hint.
 609
 610 #+begin_src emacs-lisp
 611 (setq initial-scratch-message nil)
 612 #+end_src
 613
 614 Also, let's use Text mode as the major mode, in case I want to
 615 customize it (=*scratch*='s default major mode, Fundamental mode,
 616 can't really be customized).
 617
 618 #+begin_src emacs-lisp
 619 (setq initial-major-mode 'text-mode)
 620 #+end_src
 621
 622 Inhibit the buffer list when more than 2 files are loaded.
 623
 624 #+begin_src emacs-lisp
 625 (setq inhibit-startup-buffer-menu t)
 626 #+end_src
 627
 628 I don't really need to see the startup screen or echo area message
 629 either.
 630
 631 #+begin_src emacs-lisp
 632 (advice-add #'display-startup-echo-area-message :override #'ignore)

 635 #+end_src
 636
 637 *** More useful frame titles
 638
 639 Show either the file name or the buffer name (in case the buffer isn't
 640 visiting a file). Borrowed from Emacs Prelude.
 641
 642 #+begin_src emacs-lisp
 643 (setq frame-title-format
 644       '("" invocation-name " - "

 647                  "%b"))))
 648 #+end_src
 649
 650 *** Backups
 651
 652 Emacs' default backup settings aren't that great. Let's use more
 653 sensible options. See documentation for the ~make-backup-file~
 654 variable.
 655
 656 #+begin_src emacs-lisp

 831 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
