  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))

 192 #+begin_src emacs-lisp

 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
 237 ;; (require 'borg-nix-shell)
 238 ;; (setq borg-build-shell-command 'borg-nix-shell-build-command)

 240 (with-eval-after-load 'bind-key
 241   (bind-keys
 242    :package borg
 243    ("C-c B A" . borg-activate)
 244    ("C-c B a" . borg-assimilate)
 245    ("C-c B b" . borg-build)
 246    ("C-c B c" . borg-clone)))
 247 #+end_src
 248
 249 *** =use-package=
 250
 251 #+begin_quote
 252 A use-package declaration for simplifying your .emacs
 253 #+end_quote
 254
 255 [[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
 256 packages (in our case especially the latter) in a neatly organized way
 257 and without compromising on performance.
 258
 259 #+begin_src emacs-lisp
 260 (require 'use-package)
 261 (if nil  ; set to t when need to debug init
 262     (setq use-package-verbose t
 263           use-package-expand-minimally nil
 264           use-package-compute-statistics t
 265           debug-on-error t)
 266   (setq use-package-verbose nil
 267         use-package-expand-minimally t))
 268 #+end_src
 269
 270 *** Epkg
 271
 272 #+begin_quote
 273 Browse the Emacsmirror package database
 274 #+end_quote
 275
 276 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
 277 database, low-level functions for querying the database, and a
 278 =package.el=-like user interface for browsing the available packages.
 279
 280 #+begin_src emacs-lisp
 281 (use-package epkg
 282   :defer t
 283   :bind
 284   (("C-c B d" . epkg-describe-package)
 285    ("C-c B p" . epkg-list-packages)
 286    ("C-c B r" . borg-remove)
 287    ("C-c B u" . epkg-update)))
 288 #+end_src
 289
 290 ** No littering in =~/.emacs.d=
 291
 292 #+begin_quote
 293 Help keeping ~/.emacs.d clean
 294 #+end_quote
 295
 296 By default, even for Emacs' built-in packages, the configuration files
 297 and persistent data are all over the place. Use =no-littering= to help
 298 contain the mess.
 299
 300 #+begin_src emacs-lisp
 301 (use-package no-littering
 302   :demand t
 303   :config
 304   (savehist-mode 1)
 305   (add-to-list 'savehist-additional-variables 'kill-ring)

 307   (setq auto-save-file-name-transforms
 308         `((".*" ,(no-littering-expand-var-file-name "auto-save/") t))))
 309 #+end_src
 310
 311 ** Custom file (=custom.el=)
 312
 313 I'm not planning on using the custom file much, but even so, I
 314 definitely don't want it mixing with =init.el=. So, here; let's give
 315 it it's own file. While at it, treat themes as safe.
 316
 317 #+begin_src emacs-lisp
 318 (use-package custom
 319   :no-require t
 320   :config
 321   (setq custom-file (no-littering-expand-etc-file-name "custom.el"))
 322   (when (file-exists-p custom-file)
 323     (load custom-file))
 324   (setf custom-safe-themes t))
 325 #+end_src
 326

 330 (load (no-littering-expand-etc-file-name "secrets"))
 331 #+end_src
 332
 333 ** Better =$PATH= handling
 334
 335 Let's use [[https://github.com/purcell/exec-path-from-shell][exec-path-from-shell]] to make Emacs use the =$PATH= as set up
 336 in my shell.
 337
 338 #+begin_src emacs-lisp
 339 (use-package exec-path-from-shell
 340   :defer 1
 341   :init
 342   (setq exec-path-from-shell-check-startup-files nil)
 343   :config
 344   (exec-path-from-shell-initialize)
 345   ;; while we're at it, let's fix access to our running ssh-agent
 346   (exec-path-from-shell-copy-env "SSH_AGENT_PID")
 347   (exec-path-from-shell-copy-env "SSH_AUTH_SOCK"))
 348 #+end_src
 349
 350 ** Only one custom theme at a time
 351
 352 #+begin_src emacs-lisp
 353 (defadvice load-theme (before clear-previous-themes activate)
 354   "Clear existing theme settings instead of layering them"
 355   (mapc #'disable-theme custom-enabled-themes))
 356 #+end_src
 357
 358 ** Server
 359
 360 Start server if not already running. Alternatively, can be done by
 361 issuing =emacs --daemon= in the terminal, which can be automated with
 362 a systemd service or using =brew services start emacs= on macOS. I use
 363 Emacs as my window manager (via EXWM), so I always start Emacs on
 364 login; so starting the server from inside Emacs is good enough for me.
 365
 366 See [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Emacs-Server.html#Emacs-Server][Using Emacs as a Server]].

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

 516 Save what I copy into clipboard from other applications into Emacs'
 517 kill-ring, which would allow me to still be able to easily access it
 518 in case I kill (cut or copy) something else inside Emacs before
 519 yanking (pasting) what I'd originally intended to.

 541 *** Startup screen and =*scratch*=
 542
 543 Firstly, let Emacs know that I'd like to have =*scratch*= as my
 544 startup buffer.
 545
 546 #+begin_src emacs-lisp
 547 (setq initial-buffer-choice t)
 548 #+end_src

 550 Now let's customize the =*scratch*= buffer a bit. First off, I don't
 551 need the default hint.

 553 #+begin_src emacs-lisp
 554 (setq initial-scratch-message nil)
 555 #+end_src
 556
 557 Also, let's use Text mode as the major mode, in case I want to
 558 customize it (=*scratch*='s default major mode, Fundamental mode,
 559 can't really be customized).
 560
 561 #+begin_src emacs-lisp
