  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))
 188 #+end_src
 189
 190 ** whoami
 191
 192 #+begin_src emacs-lisp
 193 (setq user-full-name "Amin Bandali"
 194       user-mail-address "amin@aminb.org")
 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))
 234 (require 'borg)
 235 (borg-initialize)
 236 #+end_src
 237
 238 *** =use-package=
 239
 240 #+begin_quote
 241 A use-package declaration for simplifying your .emacs
 242 #+end_quote
 243
 244 [[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
 245 packages (in our case especially the latter) in a neatly organized way
 246 and without compromising on performance.
 247
 248 #+begin_src emacs-lisp
 249 (require 'use-package)
 250 (if nil  ; set to t when need to debug init
 251     (setq use-package-verbose t
 252           use-package-expand-minimally nil
 253           use-package-compute-statistics t
 254           debug-on-error t)
 255   (setq use-package-verbose nil
 256         use-package-expand-minimally t))
 257 #+end_src
 258
 259 *** Epkg
 260
 261 #+begin_quote
 262 Browse the Emacsmirror package database
 263 #+end_quote
 264
 265 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
 266 database, low-level functions for querying the database, and a
 267 =package.el=-like user interface for browsing the available packages.
 268
 269 #+begin_src emacs-lisp
 270 (use-package epkg
 271   :defer t)
 272 #+end_src
 273
 274 ** No littering in =~/.emacs.d=
 275
 276 #+begin_quote
 277 Help keeping ~/.emacs.d clean
 278 #+end_quote
 279
 280 By default, even for Emacs' built-in packages, the configuration files
 281 and persistent data are all over the place. Use =no-littering= to help
 282 contain the mess.
 283
 284 #+begin_src emacs-lisp
 285 (use-package no-littering
 286   :demand t
 287   :config
 288   (savehist-mode 1)
 289   (add-to-list 'savehist-additional-variables 'kill-ring)
 290   (save-place-mode 1)
 291   (setq auto-save-file-name-transforms
 292         `((".*" ,(no-littering-expand-var-file-name "auto-save/") t))))
 293 #+end_src
 294
 295 ** Custom file (=custom.el=)
 296
 297 I'm not planning on using the custom file much, but even so, I
 298 definitely don't want it mixing with =init.el=. So, here; let's give
 299 it it's own file. While at it, treat themes as safe.
 300
 301 #+begin_src emacs-lisp
 302 (use-package custom
 303   :no-require t
 304   :config
 305   (setq custom-file (no-littering-expand-etc-file-name "custom.el"))
 306   (when (file-exists-p custom-file)
 307     (load custom-file))
 308   (setf custom-safe-themes t))
 309 #+end_src
 310
 311 ** Better =$PATH= handling
 312
 313 Let's use [[https://github.com/purcell/exec-path-from-shell][exec-path-from-shell]] to make Emacs use the =$PATH= as set up
 314 in my shell.
 315
 316 #+begin_src emacs-lisp
 317 (use-package exec-path-from-shell
 318   :defer 1
 319   :init
 320   (setq exec-path-from-shell-check-startup-files nil)
 321   :config
 322   (exec-path-from-shell-initialize)
 323   ;; while we're at it, let's fix access to our running ssh-agent
 324   (exec-path-from-shell-copy-env "SSH_AGENT_PID")
 325   (exec-path-from-shell-copy-env "SSH_AUTH_SOCK"))
 326 #+end_src
 327
 328 ** Only one custom theme at a time
 329
 330 #+begin_src emacs-lisp
 331 (defadvice load-theme (before clear-previous-themes activate)
 332   "Clear existing theme settings instead of layering them"
 333   (mapc #'disable-theme custom-enabled-themes))
 334 #+end_src
 335
 336 ** Server
 337
 338 Start server if not already running. Alternatively, can be done by
 339 issuing =emacs --daemon= in the terminal, which can be automated with
 340 a systemd service or using =brew services start emacs= on macOS. I use
 341 Emacs as my window manager (via EXWM), so I always start Emacs on
 342 login; so starting the server from inside Emacs is good enough for me.
 343
 344 See [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Emacs-Server.html#Emacs-Server][Using Emacs as a Server]].
 345

 348   :config (or (server-running-p) (server-mode)))
 349 #+end_src

 437
 438 *** Time and battery in mode-line
 439
 440 Enable displaying time and battery in the mode-line, since I'm not
 441 using the Xfce panel anymore. Also, I don't need to see the load
 442 average on a regular basis, so disable that.
 443
 444 Note: using =i3status= on sway at the moment, so disabling this.

 479 *** Kill-ring
 480
 481 Save what I copy into clipboard from other applications into Emacs'
 482 kill-ring, which would allow me to still be able to easily access it
 483 in case I kill (cut or copy) something else inside Emacs before
 484 yanking (pasting) what I'd originally intended to.

 515 Now let's customize the =*scratch*= buffer a bit. First off, I don't
 516 need the default hint.
 517
 518 #+begin_src emacs-lisp
 519 (setq initial-scratch-message nil)
 520 #+end_src
 521
 522 Also, let's use Text mode as the major mode, in case I want to
 523 customize it (=*scratch*='s default major mode, Fundamental mode,
 524 can't really be customized).
 525
 526 #+begin_src emacs-lisp
 527 (setq initial-major-mode 'text-mode)
 528 #+end_src
 529
 530 Inhibit the buffer list when more than 2 files are loaded.
 531
 532 #+begin_src emacs-lisp
 533 (setq inhibit-startup-buffer-menu t)
 534 #+end_src
 535
 536 I don't really need to see the startup screen or echo area message
 537 either.
 538
 539 #+begin_src emacs-lisp
 540 (advice-add #'display-startup-echo-area-message :override #'ignore)

 545 *** More useful frame titles
 546
 547 Show either the file name or the buffer name (in case the buffer isn't
 548 visiting a file). Borrowed from Emacs Prelude.
 549

 558 *** Backups
 559
 560 Emacs' default backup settings aren't that great. Let's use more

 562 variable.

 592 immensely enhance the Emacs experience for me; both using Emacs, and
 593 customizing it.
