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

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

 144
 145 If you would like a byte-compiled init file, set the following
 146 variable to ~t~, otherwise set it to ~nil~.
 147
 148 #+begin_src emacs-lisp
 149 (defvar a/byte-compiled-init t
 150   "If non-nil, byte-(re)compile init.el on successful tangles.")

 154
 155 ** Emacs initialization
 156
 157 I'd like to do a couple of measurements of Emacs' startup time. First,
 158 let's see how long Emacs takes to start up, before even loading
 159 =init.el=, i.e. =user-init-file=:
 160
 161 #+begin_src emacs-lisp
 162 (defvar a/before-user-init-time (current-time)
 163   "Value of `current-time' when Emacs begins loading `user-init-file'.")
 164 (message "Loading Emacs...done (%.3fs)"
 165          (float-time (time-subtract a/before-user-init-time
 166                                     before-init-time)))
 167 #+end_src
 168
 169 Also, temporarily increase ~gc-cons-threshhold~ and
 170 ~gc-cons-percentage~ during startup to reduce garbage collection
 171 frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
 172 startup time as well.
 173
 174 #+begin_src emacs-lisp
 175 (defvar a/gc-cons-threshold gc-cons-threshold)
 176 (defvar a/gc-cons-percentage gc-cons-percentage)
 177 (defvar a/file-name-handler-alist file-name-handler-alist)
 178 (setq gc-cons-threshold (* 400 1024 1024)  ; 400 MiB
 179       gc-cons-percentage 0.6
 180       file-name-handler-alist nil
 181       ;; sidesteps a bug when profiling with esup
 182       esup-child-profile-require-level 0)
 183 #+end_src
 184
 185 Of course, we'd like to set them back to their defaults once we're
 186 done initializing.
 187
 188 #+begin_src emacs-lisp
 189 (add-hook
 190  'after-init-hook
 191  (lambda ()
 192    (setq gc-cons-threshold a/gc-cons-threshold
 193          gc-cons-percentage a/gc-cons-percentage
 194          file-name-handler-alist a/file-name-handler-alist)))
 195 #+end_src
 196
 197 Increase the number of lines kept in message logs (the =*Messages*=
 198 buffer).
 199
 200 #+begin_src emacs-lisp
 201 (setq message-log-max 20000)
 202 #+end_src
 203
 204 Optionally, we could suppress some byte compiler warnings like below,
 205 but for now I've decided to keep them enabled. See documentation for
 206 ~byte-compile-warnings~ for more details.
 207
 208 #+begin_src emacs-lisp
 209 ;; (setq byte-compile-warnings
 210 ;;       '(not free-vars unresolved noruntime lexical make-local))

 215 #+begin_src emacs-lisp

 218 #+end_src
 219
 220 ** Package management
 221
 222 *** No =package.el=
 223
 224 I can do all my package management things with =straight.el=, and
 225 don't need Emacs' built-in =package.el=.  Emacs 27 lets us disable
 226 =package.el= in the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
 227
 228 #+begin_src emacs-lisp :tangle early-init.el
 229 (setq package-enable-at-startup nil)
 230 #+end_src
 231
 232 But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
 233 right now), and even when released it'll be long before most distros
 234 ship in their repos, I'll still put the old workaround with the
 235 commented call to ~package-initialize~ here anyway.
 236
 237 #+begin_src emacs-lisp :tangle no
 238 (setq package-enable-at-startup nil)
 239 ;; (package-initialize)
 240 #+end_src
 241
 242 Update: the above is not necessary, since =straight.el= automatically
 243 does that (and more).  See =straight-package-neutering-mode=.
 244
 245 *** =straight.el=

 284 (setq straight-use-package-by-default t)

 286
 287 Since we enable =straight.el='s =straight-use-package-by-default=

 289 =use-package= without any of the =straight.el= stuff.
 290

 346 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package

 584 ** Defaults
 585
 586 *** Time and battery in mode-line
 587
 588 Enable displaying time and battery in the mode-line, since I'm not
 589 using the Xfce panel anymore. Also, I don't need to see the load
 590 average on a regular basis, so disable that.
 591
 592 Note: using =i3status= on sway at the moment, so disabling this.

 603   (display-battery-mode))
 604 #+end_src
 605
 606 *** Smaller fringe
 607
 608 Might want to set the fringe to a smaller value, especially if using
 609 EXWM. I'm fine with the default for now.
 610
 611 #+begin_src emacs-lisp
 612 ;; (fringe-mode '(3 . 1))
 613 (fringe-mode nil)
 614 #+end_src
 615
 616 *** Disable disabled commands
 617
 618 Emacs disables some commands by default that could persumably be
 619 confusing for novice users. Let's disable that.
 620
 621 #+begin_src emacs-lisp
 622 (setq disabled-command-function nil)
 623 #+end_src
 624
 625 *** Kill-ring
 626
 627 Save what I copy into clipboard from other applications into Emacs'
 628 kill-ring, which would allow me to still be able to easily access it
 629 in case I kill (cut or copy) something else inside Emacs before
 630 yanking (pasting) what I'd originally intended to.
 631
 632 #+begin_src emacs-lisp
 633 (setq save-interprogram-paste-before-kill t)
 634 #+end_src
 635
 636 *** Minibuffer
 637
 638 #+begin_src emacs-lisp
 639 (setq enable-recursive-minibuffers t
 640       resize-mini-windows t)
 641 #+end_src
 642
 643 *** Lazy-person-friendly yes/no prompts
 644
 645 Lazy people would prefer to type fewer keystrokes, especially for yes
 646 or no questions. I'm lazy.
 647
 648 #+begin_src emacs-lisp
 649 (defalias 'yes-or-no-p #'y-or-n-p)
 650 #+end_src
 651
 652 *** Startup screen and =*scratch*=
 653
 654 Firstly, let Emacs know that I'd like to have =*scratch*= as my
 655 startup buffer.
 656
 657 #+begin_src emacs-lisp
 658 (setq initial-buffer-choice t)
 659 #+end_src
 660
 661 Now let's customize the =*scratch*= buffer a bit. First off, I don't
 662 need the default hint.
 663
 664 #+begin_src emacs-lisp
 665 (setq initial-scratch-message nil)
 666 #+end_src
 667
 668 Also, let's use Text mode as the major mode, in case I want to
 669 customize it (=*scratch*='s default major mode, Fundamental mode,
 670 can't really be customized).
 671
 672 #+begin_src emacs-lisp
 673 (setq initial-major-mode 'text-mode)
 674 #+end_src
 675
 676 Inhibit the buffer list when more than 2 files are loaded.
 677
 678 #+begin_src emacs-lisp
 679 (setq inhibit-startup-buffer-menu t)
 680 #+end_src
 681
 682 I don't really need to see the startup screen or echo area message
 683 either.
 684
 685 #+begin_src emacs-lisp
 686 (advice-add #'display-startup-echo-area-message :override #'ignore)
 687 (setq inhibit-startup-screen t
 688       inhibit-startup-echo-area-message user-login-name)
 689 #+end_src
 690
 691 *** More useful frame titles
 692
 693 Show either the file name or the buffer name (in case the buffer isn't
 694 visiting a file). Borrowed from Emacs Prelude.
 695
 696 #+begin_src emacs-lisp
 697 (setq frame-title-format
 698       '("" invocation-name " - "
 699         (:eval (if (buffer-file-name)
 700                    (abbreviate-file-name (buffer-file-name))
 701                  "%b"))))
 702 #+end_src
 703
 704 *** Backups
 705
 706 Emacs' default backup settings aren't that great. Let's use more
 707 sensible options. See documentation for the ~make-backup-file~
 708 variable.
 709
 710 #+begin_src emacs-lisp
 711 (setq backup-by-copying t
 712       version-control t
 713       delete-old-versions t)
 714 #+end_src

 717
 718 Enable automatic reloading of changed buffers and files.
 719
 720 #+begin_src emacs-lisp
 721 (global-auto-revert-mode 1)
 722 (setq auto-revert-verbose nil
