  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

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

 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 amin--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 amin--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 amin--gc-cons-threshold gc-cons-threshold)
 155 (defvar amin--gc-cons-percentage gc-cons-percentage)
 156 (defvar amin--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    (setq gc-cons-threshold amin--gc-cons-threshold
 172          gc-cons-percentage amin--gc-cons-percentage
 173          file-name-handler-alist amin--file-name-handler-alist)))
 174 #+end_src
 175
 176 Increase the number of lines kept in message logs (the =*Messages*=
 177 buffer).
 178
 179 #+begin_src emacs-lisp
 180 (setq message-log-max 20000)
 181 #+end_src
 182
 183 Optionally, we could suppress some byte compiler warnings like below,
 184 but for now I've decided to keep them enabled. See documentation for
 185 ~byte-compile-warnings~ for more details.
 186
 187 #+begin_src emacs-lisp
 188 ;; (setq byte-compile-warnings
 189 ;;       '(not free-vars unresolved noruntime lexical make-local))
 190 #+end_src
 191
 192 ** whoami
 193
 194 #+begin_src emacs-lisp
 195 (setq user-full-name "Amin Bandali"
 196       user-mail-address "amin@aminb.org")
 197 #+end_src
 198
 199 ** Package management
 200
 201 *** No =package.el=
 202
 203 I can do all my package management things with Borg, and don't need
 204 Emacs' built-in =package.el=. Emacs 27 lets us disable =package.el= in
 205 the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
 206
 207 #+begin_src emacs-lisp :tangle early-init.el
 208 (setq package-enable-at-startup nil)
 209 #+end_src
 210
 211 But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
 212 right now), and even when released it'll be long before most distros
 213 ship in their repos, I'll still put the old workaround with the
 214 commented call to ~package-initialize~ here anyway.
 215
 216 #+begin_src emacs-lisp
 217 (setq package-enable-at-startup nil)
 218 ;; (package-initialize)
 219 #+end_src
 220
 221 *** Borg
 222
 223 #+begin_quote
 224 Assimilate Emacs packages as Git submodules
 225 #+end_quote
 226
 227 [[https://github.com/emacscollective/borg][Borg]] is at the heart of package management of my Emacs setup. In
 228 short, it creates a git submodule in =lib/= for each package, which
 229 can then be managed with the help of Magit or other tools.
 230
 231 #+begin_src emacs-lisp
 232 (setq user-init-file (or load-file-name buffer-file-name)
 233       user-emacs-directory (file-name-directory user-init-file))
 234 (add-to-list 'load-path
 235              (expand-file-name "lib/borg" user-emacs-directory))
 236 (require 'borg)
 237 (borg-initialize)
 238
 239 ;; (require 'borg-nix-shell)
 240 ;; (setq borg-build-shell-command 'borg-nix-shell-build-command)
 241
 242 (with-eval-after-load 'bind-key
 243   (bind-keys
 244    :package borg
 245    ("C-c b A" . borg-activate)
 246    ("C-c b a" . borg-assimilate)
 247    ("C-c b b" . borg-build)
 248    ("C-c b c" . borg-clone)
 249    ("C-c b r" . borg-remove)))
 250 #+end_src
 251
 252 *** =use-package=
 253
 254 #+begin_quote
 255 A use-package declaration for simplifying your .emacs
 256 #+end_quote
 257
 258 [[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
 259 packages (in our case especially the latter) in a neatly organized way
 260 and without compromising on performance.
 261
 262 #+begin_src emacs-lisp
 263 (require 'use-package)
 264 (if nil  ; set to t when need to debug init
 265     (setq use-package-verbose t
 266           use-package-expand-minimally nil
 267           use-package-compute-statistics t
 268           debug-on-error t)
 269   (setq use-package-verbose nil
 270         use-package-expand-minimally t))
 271 #+end_src
 272
 273 *** Epkg
 274
 275 #+begin_quote
 276 Browse the Emacsmirror package database
 277 #+end_quote
 278
 279 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
 280 database, low-level functions for querying the database, and a
 281 =package.el=-like user interface for browsing the available packages.
 282
 283 #+begin_src emacs-lisp
 284 (use-package epkg
 285   :defer t
 286   :bind
 287   (("C-c b d" . epkg-describe-package)
 288    ("C-c b p" . epkg-list-packages)
 289    ("C-c b u" . epkg-update)))
 290 #+end_src
 291
 292 ** No littering in =~/.emacs.d=
 293
 294 #+begin_quote
 295 Help keeping ~/.emacs.d clean
 296 #+end_quote
 297
 298 By default, even for Emacs' built-in packages, the configuration files
 299 and persistent data are all over the place. Use =no-littering= to help
 300 contain the mess.
 301
 302 #+begin_src emacs-lisp
 303 (use-package no-littering
 304   :demand t
 305   :config
 306   (savehist-mode 1)
 307   (add-to-list 'savehist-additional-variables 'kill-ring)
 308   (save-place-mode 1)
 309   (setq auto-save-file-name-transforms
 310         `((".*" ,(no-littering-expand-var-file-name "auto-save/") t))))
 311 #+end_src
 312
 313 ** Custom file (=custom.el=)
 314
 315 I'm not planning on using the custom file much, but even so, I
 316 definitely don't want it mixing with =init.el=. So, here; let's give
 317 it it's own file. While at it, treat themes as safe.
 318
 319 #+begin_src emacs-lisp
 320 (use-package custom
 321   :no-require t
 322   :config
 323   (setq custom-file (no-littering-expand-etc-file-name "custom.el"))
 324   (when (file-exists-p custom-file)
 325     (load custom-file))
 326   (setf custom-safe-themes t))
 327 #+end_src
 328
 329 ** Secrets file
 330
 331 Load the secrets file if it exists, otherwise show a warning.
 332
 333 #+begin_src emacs-lisp

 335     (load (no-littering-expand-etc-file-name "secrets")))
 336 #+end_src
 337
 338 ** Better =$PATH= handling
 339
 340 Let's use [[https://github.com/purcell/exec-path-from-shell][exec-path-from-shell]] to make Emacs use the =$PATH= as set up
 341 in my shell.
 342
 343 #+begin_src emacs-lisp
 344 (use-package exec-path-from-shell
 345   :defer 1
 346   :init
 347   (setq exec-path-from-shell-check-startup-files nil)
 348   :config

 350   ;; while we're at it, let's fix access to our running ssh-agent
 351   (exec-path-from-shell-copy-env "SSH_AGENT_PID")
 352   (exec-path-from-shell-copy-env "SSH_AUTH_SOCK"))
 353 #+end_src
 354
 355 ** COMMENT Only one custom theme at a time
 356
 357 #+begin_src emacs-lisp
 358 (defadvice load-theme (before clear-previous-themes activate)
 359   "Clear existing theme settings instead of layering them"

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

 502 using the Xfce panel anymore. Also, I don't need to see the load
 503 average on a regular basis, so disable that.

 505 Note: using =i3status= on sway at the moment, so disabling this.

 539

 542 in case I kill (cut or copy) something else inside Emacs before

 565 *** Startup screen and =*scratch*=
 566
 567 Firstly, let Emacs know that I'd like to have =*scratch*= as my
 568 startup buffer.
 569
 570 #+begin_src emacs-lisp
 571 (setq initial-buffer-choice t)
 572 #+end_src
 573
 574 Now let's customize the =*scratch*= buffer a bit. First off, I don't
 575 need the default hint.
 576
 577 #+begin_src emacs-lisp
 578 (setq initial-scratch-message nil)
 579 #+end_src
 580
 581 Also, let's use Text mode as the major mode, in case I want to
 582 customize it (=*scratch*='s default major mode, Fundamental mode,
 583 can't really be customized).
 584
 585 #+begin_src emacs-lisp
 586 (setq initial-major-mode 'text-mode)
 587 #+end_src
 588
 589 Inhibit the buffer list when more than 2 files are loaded.
 590
 591 #+begin_src emacs-lisp
 592 (setq inhibit-startup-buffer-menu t)
 593 #+end_src
 594
 595 I don't really need to see the startup screen or echo area message
 596 either.

 617 *** Backups
