  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

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

 132 ** Emacs initialization
 133
 134 I'd like to do a couple of measurements of Emacs' startup time. First,
 135 let'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
 146 Also, temporarily increase ~gc-cons-threshhold~ and
 147 ~gc-cons-percentage~ during startup to reduce garbage collection
 148 frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
 149 startup 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
 162 Of course, we'd like to set them back to their defaults once we're
 163 done 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
 174 Increase the number of lines kept in message logs (the =*Messages*=
 175 buffer).
 176
 177 #+begin_src emacs-lisp
 178 (setq message-log-max 20000)
 179 #+end_src
 180
 181 Optionally, we could suppress some byte compiler warnings like below,
 182 but 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
 186 ;; (setq byte-compile-warnings
 187 ;;       '(not free-vars unresolved noruntime lexical make-local))

 192 #+begin_src emacs-lisp

 194       user-mail-address "amin@bandali.me")
 195 #+end_src
 196
 197 ** Package management
 198
 199 *** No =package.el=
 200
 201 I can do all my package management things with Borg, and don't need
 202 Emacs' built-in =package.el=. Emacs 27 lets us disable =package.el= in
 203 the =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
 209 But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
 210 right now), and even when released it'll be long before most distros
 211 ship in their repos, I'll still put the old workaround with the
 212 commented call to ~package-initialize~ here anyway.
 213
 214 #+begin_src emacs-lisp
 215 (setq package-enable-at-startup nil)
 216 ;; (package-initialize)
 217 #+end_src
 218
 219 *** Borg
 220
 221 #+begin_quote
 222 Assimilate Emacs packages as Git submodules
 223 #+end_quote
 224
 225 [[https://github.com/emacscollective/borg][Borg]] is at the heart of package management of my Emacs setup. In
 226 short, it creates a git submodule in =lib/= for each package, which
 227 can then be managed with the help of Magit or other tools.
 228
 229 #+begin_src emacs-lisp
 230 (setq user-init-file (or load-file-name buffer-file-name)
 231       user-emacs-directory (file-name-directory user-init-file))
 232 (add-to-list 'load-path
 233              (expand-file-name "lib/borg" user-emacs-directory))

 251 *** =use-package=
 252
 253 #+begin_quote
 254 A use-package declaration for simplifying your .emacs
 255 #+end_quote
 256
 257 [[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
 258 packages (in our case especially the latter) in a neatly organized way
 259 and without compromising on performance.
 260
 261 #+begin_src emacs-lisp
 262 (require 'use-package)
 263 (if nil  ; set to t when need to debug init
 264     (setq use-package-verbose t

 270 #+end_src
 271
 272 *** Epkg
 273
 274 #+begin_quote
 275 Browse the Emacsmirror package database
 276 #+end_quote
 277
 278 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
 279 database, low-level functions for querying the database, and a
 280 =package.el=-like user interface for browsing the available packages.
 281
 282 #+begin_src emacs-lisp
 283 (use-package epkg
 284   :defer t
 285   :bind
 286   (("C-c b d" . epkg-describe-package)
 287    ("C-c b p" . epkg-list-packages)

 291 ** No littering in =~/.emacs.d=
 292
 293 #+begin_quote
 294 Help keeping ~/.emacs.d clean
 295 #+end_quote
 296
 297 By default, even for Emacs' built-in packages, the configuration files
 298 and persistent data are all over the place. Use =no-littering= to help
 299 contain the mess.
 300
 301 #+begin_src emacs-lisp
 302 (use-package no-littering
 303   :demand t
 304   :config
 305   (savehist-mode 1)

 310 #+end_src
 311
 312 ** Custom file (=custom.el=)
 313
 314 I'm not planning on using the custom file much, but even so, I
 315 definitely don't want it mixing with =init.el=. So, here; let's give
 316 it it's own file. While at it, treat themes as safe.
 317
 318 #+begin_src emacs-lisp
 319 (use-package custom
 320   :no-require t
 321   :config
 322   (setq custom-file (no-littering-expand-etc-file-name "custom.el"))

 325   (setf custom-safe-themes t))
 326 #+end_src

 336
 337 ** Better =$PATH= handling
 338
 339 Let's use [[https://github.com/purcell/exec-path-from-shell][exec-path-from-shell]] to make Emacs use the =$PATH= as set up
 340 in my shell.
 341

 361
 362 ** Server
 363
 364 Start server if not already running. Alternatively, can be done by
 365 issuing =emacs --daemon= in the terminal, which can be automated with
 366 a systemd service or using =brew services start emacs= on macOS. I use
 367 Emacs as my window manager (via EXWM), so I always start Emacs on
 368 login; so starting the server from inside Emacs is good enough for me.

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

 510 *** Disable disabled commands
 511
 512 Emacs disables some commands by default that could persumably be
 513 confusing for novice users. Let's disable that.
 514
 515 #+begin_src emacs-lisp
 516 (setq disabled-command-function nil)
 517 #+end_src
 518
 519 *** Kill-ring
 520
 521 Save what I copy into clipboard from other applications into Emacs'
 522 kill-ring, which would allow me to still be able to easily access it
 523 in case I kill (cut or copy) something else inside Emacs before
 524 yanking (pasting) what I'd originally intended to.
 525
 526 #+begin_src emacs-lisp

 534       resize-mini-windows t)
 535 #+end_src
 536
 537 *** Lazy-person-friendly yes/no prompts
 538
 539 Lazy people would prefer to type fewer keystrokes, especially for yes
 540 or no questions. I'm lazy.
 541
 542 #+begin_src emacs-lisp
 543 (defalias 'yes-or-no-p #'y-or-n-p)
 544 #+end_src
 545
 546 *** Startup screen and =*scratch*=
 547
 548 Firstly, let Emacs know that I'd like to have =*scratch*= as my
 549 startup buffer.
 550
 551 #+begin_src emacs-lisp
 552 (setq initial-buffer-choice t)
 553 #+end_src
 554
 555 Now let's customize the =*scratch*= buffer a bit. First off, I don't
 556 need the default hint.
 557
 558 #+begin_src emacs-lisp
 559 (setq initial-scratch-message nil)
 560 #+end_src
 561
 562 Also, let's use Text mode as the major mode, in case I want to
 563 customize it (=*scratch*='s default major mode, Fundamental mode,
 564 can't really be customized).
 565
 566 #+begin_src emacs-lisp
 567 (setq initial-major-mode 'text-mode)
 568 #+end_src
 569
 570 Inhibit the buffer list when more than 2 files are loaded.
 571
 572 #+begin_src emacs-lisp
 573 (setq inhibit-startup-buffer-menu t)
 574 #+end_src
 575
 576 I don't really need to see the startup screen or echo area message
 577 either.
 578
 579 #+begin_src emacs-lisp
 580 (advice-add #'display-startup-echo-area-message :override #'ignore)
 581 (setq inhibit-startup-screen t
 582       inhibit-startup-echo-area-message user-login-name)
 583 #+end_src
 584
 585 *** More useful frame titles
 586
 587 Show either the file name or the buffer name (in case the buffer isn't
 588 visiting a file). Borrowed from Emacs Prelude.
 589
 590 #+begin_src emacs-lisp
 591 (setq frame-title-format
 592       '("" invocation-name " - "
 593         (:eval (if (buffer-file-name)
 594                    (abbreviate-file-name (buffer-file-name))
 595                  "%b"))))
 596 #+end_src
 597
 598 *** Backups
 599
 600 Emacs' default backup settings aren't that great. Let's use more
 601 sensible options. See documentation for the ~make-backup-file~
 602 variable.
 603
 604 #+begin_src emacs-lisp
 605 (setq backup-by-copying t
 606       version-control t
 607       delete-old-versions t)
 608 #+end_src
 609
 610 *** Auto revert
 611
 612 Enable automatic reloading of changed buffers and files.
 613
 614 #+begin_src emacs-lisp
 615 (global-auto-revert-mode 1)

 642         "Close the compilation window if successful."
 643         ;; if M-x compile exits with 0

 651 *** Search for non-ASCII characters
 652
 653 I’d like non-ASCII characters such as ‘’“”«»‹›áⓐ𝒶 to be selected when
 654 I search for their ASCII counterpart.  Shoutout to [[http://endlessparentheses.com/new-in-emacs-25-1-easily-search-non-ascii-characters.html][endlessparentheses]]
 655 for this.

 675 ** Packages
 676
 677 The packages in this section are absolutely essential to my everyday
 678 workflow, and they play key roles in how I do my computing. They
 679 immensely enhance the Emacs experience for me; both using Emacs, and
 680 customizing it.

2327 Manually install bbdb (=lisp/bbdb= copied from an ELPA-based setup),
2328 because installing it from source on Emacs 27 using the following
2329 submodule configuration for some reason doesn’t work and results in
2330 very strange errors when using any of the functions.
