  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 ** whoami
 192
 193 #+begin_src emacs-lisp
 194 (setq user-full-name "Amin Bandali"
 195       user-mail-address "amin@aminb.org")
 196 #+end_src
 197
 198 ** Package management
 199
 200 *** No =package.el=
 201
 202 I can do all my package management things with Borg, and don't need
 203 Emacs' built-in =package.el=. Emacs 27 lets us disable =package.el= in
 204 the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
 205
 206 #+begin_src emacs-lisp :tangle early-init.el
 207 (setq package-enable-at-startup nil)
 208 #+end_src
 209
 210 But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
 211 right now), and even when released it'll be long before most distros
 212 ship in their repos, I'll still put the old workaround with the
 213 commented call to ~package-initialize~ here anyway.
 214
 215 #+begin_src emacs-lisp
 216 (setq package-enable-at-startup nil)
 217 ;; (package-initialize)
 218 #+end_src
 219
 220 *** Borg
 221
 222 #+begin_quote
 223 Assimilate Emacs packages as Git submodules
 224 #+end_quote
 225
 226 [[https://github.com/emacscollective/borg][Borg]] is at the heart of package management of my Emacs setup. In
 227 short, it creates a git submodule in =lib/= for each package, which
 228 can then be managed with the help of Magit or other tools.
 229
 230 #+begin_src emacs-lisp
 231 (setq user-init-file (or load-file-name buffer-file-name)
 232       user-emacs-directory (file-name-directory user-init-file))
 233 (add-to-list 'load-path
 234              (expand-file-name "lib/borg" user-emacs-directory))
 235 (require 'borg)
 236 (borg-initialize)
 237 #+end_src
 238
 239 *** =use-package=
 240
 241 #+begin_quote
 242 A use-package declaration for simplifying your .emacs
 243 #+end_quote
 244
 245 [[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
 246 packages (in our case especially the latter) in a neatly organized way
 247 and without compromising on performance.
 248
 249 #+begin_src emacs-lisp
 250 (require 'use-package)
 251 (if nil  ; set to t when need to debug init
 252     (setq use-package-verbose t
 253           use-package-expand-minimally nil
 254           use-package-compute-statistics t
 255           debug-on-error t)
 256   (setq use-package-verbose nil
 257         use-package-expand-minimally t))
 258 #+end_src
 259
 260 *** Epkg
 261
 262 #+begin_quote
 263 Browse the Emacsmirror package database
 264 #+end_quote
 265
 266 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
 267 database, low-level functions for querying the database, and a
 268 =package.el=-like user interface for browsing the available packages.
 269
 270 #+begin_src emacs-lisp
 271 (use-package epkg
 272   :defer t)
 273 #+end_src
 274
 275 ** No littering in =~/.emacs.d=
 276
 277 #+begin_quote
 278 Help keeping ~/.emacs.d clean
 279 #+end_quote
 280
 281 By default, even for Emacs' built-in packages, the configuration files
 282 and persistent data are all over the place. Use =no-littering= to help
 283 contain the mess.
 284
 285 #+begin_src emacs-lisp
 286 (use-package no-littering
 287   :demand t
 288   :config
 289   (savehist-mode 1)
 290   (add-to-list 'savehist-additional-variables 'kill-ring)
 291   (save-place-mode 1)
 292   (setq auto-save-file-name-transforms
 293         `((".*" ,(no-littering-expand-var-file-name "auto-save/") t))))
 294 #+end_src
 295
 296 ** Custom file (=custom.el=)
 297
 298 I'm not planning on using the custom file much, but even so, I
 299 definitely don't want it mixing with =init.el=. So, here; let's give
 300 it it's own file. While at it, treat themes as safe.
 301
 302 #+begin_src emacs-lisp
 303 (use-package custom
 304   :no-require t
 305   :config
 306   (setq custom-file (no-littering-expand-etc-file-name "custom.el"))
 307   (when (file-exists-p custom-file)
 308     (load custom-file))
 309   (setf custom-safe-themes t))
 310 #+end_src
 311
 312 ** Better =$PATH= handling
 313
 314 Let's use [[https://github.com/purcell/exec-path-from-shell][exec-path-from-shell]] to make Emacs use the =$PATH= as set up
 315 in my shell.
 316
 317 #+begin_src emacs-lisp
 318 (use-package exec-path-from-shell
 319   :defer 1
 320   :init
 321   (setq exec-path-from-shell-check-startup-files nil)
 322   :config
 323   (exec-path-from-shell-initialize)
 324   ;; while we're at it, let's fix access to our running ssh-agent
 325   (exec-path-from-shell-copy-env "SSH_AGENT_PID")
 326   (exec-path-from-shell-copy-env "SSH_AUTH_SOCK"))
 327 #+end_src
 328
 329 ** Only one custom theme at a time
 330
 331 #+begin_src emacs-lisp
 332 (defadvice load-theme (before clear-previous-themes activate)
 333   "Clear existing theme settings instead of layering them"
 334   (mapc #'disable-theme custom-enabled-themes))
 335 #+end_src
 336
 337 ** Server
 338
 339 Start server if not already running. Alternatively, can be done by
 340 issuing =emacs --daemon= in the terminal, which can be automated with
 341 a systemd service or using =brew services start emacs= on macOS. I use
 342 Emacs as my window manager (via EXWM), so I always start Emacs on
 343 login; so starting the server from inside Emacs is good enough for me.
 344
 345 See [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Emacs-Server.html#Emacs-Server][Using Emacs as a Server]].

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

 461 Might want to set the fringe to a smaller value, especially if using
 462 EXWM. I'm fine with the default for now.

 469 *** Disable disabled commands
 470

 472 confusing for novice users. Let's disable that.

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

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

 544 *** More useful frame titles

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

 557 *** Backups

 587 ** Packages

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