  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 tangle-init
  48 make bootstrap
  49 make build

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

 134 ** Emacs initialization
 135
 136 I'd like to do a couple of measurements of Emacs' startup time. First,
 137 let's see how long Emacs takes to start up, before even loading
 138 =init.el=, i.e. =user-init-file=:
 139
 140 #+begin_src emacs-lisp
 141 (defvar ab--before-user-init-time (current-time)
 142   "Value of `current-time' when Emacs begins loading `user-init-file'.")
 143 (message "Loading Emacs...done (%.3fs)"
 144          (float-time (time-subtract ab--before-user-init-time
 145                                     before-init-time)))
 146 #+end_src
 147
 148 Also, temporarily increase ~gc-cons-threshhold~ and
 149 ~gc-cons-percentage~ during startup to reduce garbage collection
 150 frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
 151 startup time as well.
 152
 153 #+begin_src emacs-lisp
 154 (defvar ab--gc-cons-threshold gc-cons-threshold)
 155 (defvar ab--gc-cons-percentage gc-cons-percentage)
 156 (defvar ab--file-name-handler-alist file-name-handler-alist)
 157 (setq gc-cons-threshold (* 400 1024 1024)  ; 400 MiB
 158       gc-cons-percentage 0.6
 159       file-name-handler-alist nil
 160       ;; sidesteps a bug when profiling with esup
 161       esup-child-profile-require-level 0)
 162 #+end_src
 163
 164 Of course, we'd like to set them back to their defaults once we're
 165 done initializing.
 166
 167 #+begin_src emacs-lisp
 168 (add-hook
 169  'after-init-hook
 170  (lambda ()
 171    (let ((elapsed (float-time (time-subtract (current-time)
 172                                              ab--before-user-init-time))))
 173      (message "Loading %s...done (%.3fs) [after-init]"
 174               user-init-file elapsed))
 175    (setq gc-cons-threshold ab--gc-cons-threshold
 176          gc-cons-percentage ab--gc-cons-percentage
 177          file-name-handler-alist ab--file-name-handler-alist)))
 178 #+end_src
 179
 180 Increase the number of lines kept in message logs (the =*Messages*=
 181 buffer).
 182
 183 #+begin_src emacs-lisp
 184 (setq message-log-max 20000)
 185 #+end_src
 186
 187 Optionally, we could suppress some byte compiler warnings like below,
 188 but for now I've decided to keep them enabled. See documentation for
 189 ~byte-compile-warnings~ for more details.
 190
 191 #+begin_src emacs-lisp
 192 ;; (setq byte-compile-warnings
 193 ;;       '(not free-vars unresolved noruntime lexical make-local))
 194 #+end_src
 195
 196 ** Package management
 197
 198 *** No =package.el=
 199
 200 I can do all my package management things with Borg, and don't need
 201 Emacs' built-in =package.el=. Emacs 27 lets us disable =package.el= in
 202 the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
 203
 204 #+begin_src emacs-lisp :tangle early-init.el
 205 (setq package-enable-at-startup nil)
 206 #+end_src
 207
 208 But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
 209 right now), and even when released it'll be long before most distros
 210 ship in their repos, I'll still put the old workaround with the
 211 commented call to ~package-initialize~ here anyway.
 212
 213 #+begin_src emacs-lisp
 214 (setq package-enable-at-startup nil)
 215 ;; (package-initialize)
 216 #+end_src
 217
 218 *** Borg
 219
 220 #+begin_quote
 221 Assimilate Emacs packages as Git submodules
 222 #+end_quote
 223
 224 [[https://github.com/emacscollective/borg][Borg]] is at the heart of package management of my Emacs setup. In
 225 short, it creates a git submodule in =lib/= for each package, which
 226 can then be managed with the help of Magit or other tools.
 227
 228 #+begin_src emacs-lisp
 229 (setq user-init-file (or load-file-name buffer-file-name)
 230       user-emacs-directory (file-name-directory user-init-file))
 231 (add-to-list 'load-path
 232              (expand-file-name "lib/borg" user-emacs-directory))
 233 (require 'borg)
 234 (borg-initialize)
 235 #+end_src
 236
 237 *** =use-package=
 238
 239 #+begin_quote
 240 A use-package declaration for simplifying your .emacs
 241 #+end_quote
 242
 243 [[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
 244 packages (in our case especially the latter) in a neatly organized way
 245 and without compromising on performance.
 246
 247 #+begin_src emacs-lisp
 248 (require 'use-package)
 249 (if nil                             ; set to t when need to debug init
 250     (setq use-package-verbose t
 251           use-package-expand-minimally nil
 252           use-package-compute-statistics t
 253           debug-on-error t)
 254   (setq use-package-verbose nil
 255         use-package-expand-minimally t))
 256 #+end_src
 257
 258 *** Epkg
 259
 260 #+begin_quote
 261 Browse the Emacsmirror package database
 262 #+end_quote
 263
 264 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
 265 database, low-level functions for querying the database, and a
 266 =package.el=-like user interface for browsing the available packages.
 267
 268 #+begin_src emacs-lisp
 269 (use-package epkg
 270   :defer t)
 271 #+end_src
 272
 273 ** No littering in =~/.emacs.d=
 274
 275 #+begin_quote
 276 Help keeping ~/.emacs.d clean
 277 #+end_quote
 278
 279 By default, even for Emacs' built-in packages, the configuration files
 280 and persistent data are all over the place. Use =no-littering= to help
 281 contain the mess.
 282
 283 #+begin_src emacs-lisp
 284 (use-package no-littering
 285   :demand t
 286   :config
 287   (savehist-mode 1)
 288   (add-to-list 'savehist-additional-variables 'kill-ring)
 289   (save-place-mode 1)
 290   (setq auto-save-file-name-transforms
 291         `((".*" ,(no-littering-expand-var-file-name "auto-save/") t))))
 292 #+end_src
 293
 294 ** Custom file (=custom.el=)
 295
 296 I'm not planning on using the custom file much, but even so, I
 297 definitely don't want it mixing with =init.el=. So, here; let's give
 298 it it's own file. While at it, treat themes as safe.
 299
 300 #+begin_src emacs-lisp
 301 (use-package custom
 302   :no-require t
 303   :config
 304   (setq custom-file (no-littering-expand-etc-file-name "custom.el"))
 305   (when (file-exists-p custom-file)
 306     (load custom-file))
 307   (setf custom-safe-themes t))
 308 #+end_src
 309
 310 ** Better =$PATH= handling
 311
 312 Let's use [[https://github.com/purcell/exec-path-from-shell][exec-path-from-shell]] to make Emacs use the =$PATH= as set up
 313 in my shell.
 314
 315 #+begin_src emacs-lisp
 316 (use-package exec-path-from-shell
 317   :defer 1
 318   :init
 319   (setq exec-path-from-shell-check-startup-files nil)
 320   :config
 321   (exec-path-from-shell-initialize)
 322   ;; while we're at it, let's fix access to our running ssh-agent
 323   (exec-path-from-shell-copy-env "SSH_AGENT_PID")
 324   (exec-path-from-shell-copy-env "SSH_AUTH_SOCK"))
 325 #+end_src
 326
 327 ** Server
 328
 329 Start server if not already running. Alternatively, can be done by
 330 issuing =emacs --daemon= in the terminal, which can be automated with
 331 a systemd service or using =brew services start emacs= on macOS. I use
 332 Emacs as my window manager (via EXWM), so I always start Emacs on
 333 login; so starting the server from inside Emacs is good enough for me.
 334
 335 See [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Emacs-Server.html#Emacs-Server][Using Emacs as a Server]].
 336
 337 #+begin_src emacs-lisp

 347 ** Defaults
 348
 349 *** Smaller fringe
 350
 351 Might want to set the fringe to a smaller value, especially if using
 352 EXWM. I'm fine with the default for now.
 353
 354 #+begin_src emacs-lisp
 355 ;; (fringe-mode '(3 . 1))
 356 (fringe-mode nil)
 357 #+end_src
 358
 359 *** Disable disabled commands
 360
 361 Emacs disables some commands by default that could persumably be
 362 confusing for novice users. Let's disable that.
 363
 364 #+begin_src emacs-lisp
 365 (setq disabled-command-function nil)
 366 #+end_src
 367
 368 *** Kill-ring
 369
 370 Save what I copy into clipboard from other applications into Emacs'
 371 kill-ring, which would allow me to still be able to easily access it
 372 in case I kill (cut or copy) something else inside Emacs before
 373 yanking (pasting) what I'd originally intended to.
 374
 375 #+begin_src emacs-lisp
 376 (setq save-interprogram-paste-before-kill t)
 377 #+end_src
 378
 379 *** Minibuffer
 380
 381 #+begin_src emacs-lisp
 382 (setq enable-recursive-minibuffers t
 383       resize-mini-windows t)
 384 #+end_src
 385
 386 *** Lazy-person-friendly yes/no prompts
 387
 388 Lazy people would prefer to type fewer keystrokes, especially for yes
 389 or no questions. I'm lazy.
 390
 391 #+begin_src emacs-lisp
 392 (defalias 'yes-or-no-p #'y-or-n-p)
 393 #+end_src
 394
 395 *** Startup screen and =*scratch*=
 396
 397 Firstly, let Emacs know that I'd like to have =*scratch*= as my
 398 startup buffer.
 399
 400 #+begin_src emacs-lisp
 401 (setq initial-buffer-choice t)
 402 #+end_src
 403
 404 Now let's customize the =*scratch*= buffer a bit. First off, I don't
 405 need the default hint.
 406
 407 #+begin_src emacs-lisp
 408 (setq initial-scratch-message nil)
 409 #+end_src
 410
 411 Also, let's use Text mode as the major mode, in case I want to
 412 customize it (=*scratch*='s default major mode, Fundamental mode,
 413 can't really be customized).
 414
 415 #+begin_src emacs-lisp
 416 (setq initial-major-mode 'text-mode)
 417 #+end_src
 418
 419 Inhibit the buffer list when more than 2 files are loaded.
 420
 421 #+begin_src emacs-lisp
 422 (setq inhibit-startup-buffer-menu t)
 423 #+end_src
 424
 425 I don't really need to see the startup screen or echo area message
 426 either.
 427
 428 #+begin_src emacs-lisp
 429 (advice-add #'display-startup-echo-area-message :override #'ignore)
 430 (setq inhibit-startup-screen t
 431       inhibit-startup-echo-area-message user-login-name)
 432 #+end_src
 433
 434 *** More useful frame titles
 435
 436 Show either the file name or the buffer name (in case the buffer isn't
 437 visiting a file). Borrowed from Emacs Prelude.
 438
 439 #+begin_src emacs-lisp
 440 (setq frame-title-format
 441       '("" invocation-name " - "
 442         (:eval (if (buffer-file-name)
 443                    (abbreviate-file-name (buffer-file-name))
 444                  "%b"))))
 445 #+end_src
 446
 447 *** Backups
 448
 449 Emacs' default backup settings aren't that great. Let's use more
 450 sensible options. See documentation for the ~make-backup-file~
 451 variable.
 452
 453 #+begin_src emacs-lisp
 454 (setq backup-by-copying t
 455       version-control t)
 456 #+end_src
 457
 458 ** Packages
 459
 460 The packages in this section are absolutely essential to my everyday
 461 workflow, and they play key roles in how I do my computing. They
 462 immensely enhance the Emacs experience for me; both using Emacs, and
 463 customizing it.
