  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.

 133 ** Emacs initialization
 134
 135 I'd like to do a couple of measurements of Emacs' startup time. First,
 136 let's see how long Emacs takes to start up, before even loading
 137 =init.el=, i.e. =user-init-file=:
 138
 139 #+begin_src emacs-lisp
 140 (defvar ab--before-user-init-time (current-time)
 141   "Value of `current-time' when Emacs begins loading `user-init-file'.")
 142 (message "Loading Emacs...done (%.3fs)"
 143          (float-time (time-subtract ab--before-user-init-time
 144                                     before-init-time)))
 145 #+end_src
 146
 147 Also, temporarily increase ~gc-cons-threshhold~ and
 148 ~gc-cons-percentage~ during startup to reduce garbage collection
 149 frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
 150 startup time as well.
 151
 152 #+begin_src emacs-lisp
 153 (defvar ab--gc-cons-threshold gc-cons-threshold)
 154 (defvar ab--gc-cons-percentage gc-cons-percentage)
 155 (defvar ab--file-name-handler-alist file-name-handler-alist)
 156 (setq gc-cons-threshold (* 400 1024 1024)  ; 400 MiB
 157       gc-cons-percentage 0.6
 158       file-name-handler-alist nil
 159       ;; sidesteps a bug when profiling with esup
 160       esup-child-profile-require-level 0)
 161 #+end_src
 162
 163 Of course, we'd like to set them back to their defaults once we're
 164 done initializing.
 165
 166 #+begin_src emacs-lisp
 167 (add-hook
 168  'after-init-hook
 169  (lambda ()
 170    (setq gc-cons-threshold ab--gc-cons-threshold
 171          gc-cons-percentage ab--gc-cons-percentage
 172          file-name-handler-alist ab--file-name-handler-alist)))
 173 #+end_src
 174
 175 Increase the number of lines kept in message logs (the =*Messages*=
 176 buffer).
 177
 178 #+begin_src emacs-lisp
 179 (setq message-log-max 20000)
 180 #+end_src
 181
 182 Optionally, we could suppress some byte compiler warnings like below,
 183 but for now I've decided to keep them enabled. See documentation for
 184 ~byte-compile-warnings~ for more details.
 185
 186 #+begin_src emacs-lisp
 187 ;; (setq byte-compile-warnings
 188 ;;       '(not free-vars unresolved noruntime lexical make-local))
 189 #+end_src
 190
 191 ** Package management
 192
 193 *** No =package.el=
 194
 195 I can do all my package management things with Borg, and don't need
 196 Emacs' built-in =package.el=. Emacs 27 lets us disable =package.el= in
 197 the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
 198
 199 #+begin_src emacs-lisp :tangle early-init.el
 200 (setq package-enable-at-startup nil)
 201 #+end_src
 202
 203 But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
 204 right now), and even when released it'll be long before most distros
 205 ship in their repos, I'll still put the old workaround with the
 206 commented call to ~package-initialize~ here anyway.
 207
 208 #+begin_src emacs-lisp
 209 (setq package-enable-at-startup nil)
 210 ;; (package-initialize)
 211 #+end_src
 212
 213 *** Borg
 214
 215 #+begin_quote
 216 Assimilate Emacs packages as Git submodules
 217 #+end_quote
 218
 219 [[https://github.com/emacscollective/borg][Borg]] is at the heart of package management of my Emacs setup. In
 220 short, it creates a git submodule in =lib/= for each package, which
 221 can then be managed with the help of Magit or other tools.
 222
 223 #+begin_src emacs-lisp
 224 (setq user-init-file (or load-file-name buffer-file-name)
 225       user-emacs-directory (file-name-directory user-init-file))
 226 (add-to-list 'load-path
 227              (expand-file-name "lib/borg" user-emacs-directory))
 228 (require 'borg)
 229 (borg-initialize)
 230 #+end_src
 231
 232 *** =use-package=
 233
 234 #+begin_quote
 235 A use-package declaration for simplifying your .emacs
 236 #+end_quote
 237
 238 [[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
 239 packages (in our case especially the latter) in a neatly organized way
 240 and without compromising on performance.
 241
 242 #+begin_src emacs-lisp
 243 (require 'use-package)
 244 (if nil                             ; set to t when need to debug init
 245     (setq use-package-verbose t
 246           use-package-expand-minimally nil
 247           use-package-compute-statistics t
 248           debug-on-error t)
 249   (setq use-package-verbose nil
 250         use-package-expand-minimally t))
 251 #+end_src
 252
 253 *** Epkg
 254
 255 #+begin_quote
 256 Browse the Emacsmirror package database
 257 #+end_quote
 258
 259 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
 260 database, low-level functions for querying the database, and a
 261 =package.el=-like user interface for browsing the available packages.
 262
 263 #+begin_src emacs-lisp
 264 (use-package epkg
 265   :defer t)
 266 #+end_src
 267
 268 ** No littering in =~/.emacs.d=
 269
 270 #+begin_quote
 271 Help keeping ~/.emacs.d clean
 272 #+end_quote
 273
 274 By default, even for Emacs' built-in packages, the configuration files
 275 and persistent data are all over the place. Use =no-littering= to help
 276 contain the mess.
 277
 278 #+begin_src emacs-lisp
 279 (use-package no-littering
 280   :demand t
 281   :config
 282   (savehist-mode 1)
 283   (add-to-list 'savehist-additional-variables 'kill-ring)
 284   (save-place-mode 1)
 285   (setq auto-save-file-name-transforms
 286         `((".*" ,(no-littering-expand-var-file-name "auto-save/") t))))
 287 #+end_src
 288
 289 ** Custom file (=custom.el=)
 290
 291 I'm not planning on using the custom file much, but even so, I
 292 definitely don't want it mixing with =init.el=. So, here; let's give
 293 it it's own file. While at it, treat themes as safe.
 294
 295 #+begin_src emacs-lisp
 296 (use-package custom
 297   :no-require t
 298   :config
 299   (setq custom-file (no-littering-expand-etc-file-name "custom.el"))
 300   (when (file-exists-p custom-file)
 301     (load custom-file))
 302   (setf custom-safe-themes t))
 303 #+end_src
 304
 305 ** Better =$PATH= handling
 306
 307 Let's use [[https://github.com/purcell/exec-path-from-shell][exec-path-from-shell]] to make Emacs use the =$PATH= as set up
 308 in my shell.
 309
 310 #+begin_src emacs-lisp
 311 (use-package exec-path-from-shell
 312   :defer 1
 313   :init
 314   (setq exec-path-from-shell-check-startup-files nil)
 315   :config
 316   (exec-path-from-shell-initialize)
 317   ;; while we're at it, let's fix access to our running ssh-agent
 318   (exec-path-from-shell-copy-env "SSH_AGENT_PID")
 319   (exec-path-from-shell-copy-env "SSH_AUTH_SOCK"))
 320 #+end_src
 321
 322 ** Only one custom theme at a time
 323
 324 #+begin_src emacs-lisp
 325 (defadvice load-theme (before clear-previous-themes activate)
 326   "Clear existing theme settings instead of layering them"
 327   (mapc #'disable-theme custom-enabled-themes))
 328 #+end_src
 329
 330 ** Server
 331
 332 Start server if not already running. Alternatively, can be done by
 333 issuing =emacs --daemon= in the terminal, which can be automated with
 334 a systemd service or using =brew services start emacs= on macOS. I use
 335 Emacs as my window manager (via EXWM), so I always start Emacs on
 336 login; so starting the server from inside Emacs is good enough for me.
 337
 338 See [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Emacs-Server.html#Emacs-Server][Using Emacs as a Server]].
 339

 342   :config (or (server-running-p) (server-mode)))
 343 #+end_src

 430 ** Defaults
 431
 432 *** Time and battery in mode-line
 433
 434 Enable displaying time and battery in the mode-line, since I'm not
 435 using the Xfce panel anymore. Also, I don't need to see the load
 436 average on a regular basis, so disable that.

 452 *** Smaller fringe
 453
 454 Might want to set the fringe to a smaller value, especially if using
 455 EXWM. I'm fine with the default for now.

 459 (fringe-mode nil)
 460 #+end_src

 462 *** Disable disabled commands
 463
 464 Emacs disables some commands by default that could persumably be
 465 confusing for novice users. Let's disable that.
 466
 467 #+begin_src emacs-lisp
 468 (setq disabled-command-function nil)
 469 #+end_src
 470
 471 *** Kill-ring
 472
 473 Save what I copy into clipboard from other applications into Emacs'
 474 kill-ring, which would allow me to still be able to easily access it
 475 in case I kill (cut or copy) something else inside Emacs before
 476 yanking (pasting) what I'd originally intended to.

 489 *** Lazy-person-friendly yes/no prompts
 490
 491 Lazy people would prefer to type fewer keystrokes, especially for yes
 492 or no questions. I'm lazy.

 539 Show either the file name or the buffer name (in case the buffer isn't
 540 visiting a file). Borrowed from Emacs Prelude.

 561 ** Packages
 562
 563 The packages in this section are absolutely essential to my everyday
 564 workflow, and they play key roles in how I do my computing. They
 565 immensely enhance the Emacs experience for me; both using Emacs, and
 566 customizing it.
