  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.

 126
 127 ** Emacs initialization
 128
 129 I'd like to do a couple of measurements of Emacs' startup time. First,
 130 let's see how long Emacs takes to start up, before even loading
 131 =init.el=, i.e. =user-init-file=:
 132
 133 #+begin_src emacs-lisp
 134 (defvar amin--before-user-init-time (current-time)
 135   "Value of `current-time' when Emacs begins loading `user-init-file'.")
 136 (message "Loading Emacs...done (%.3fs)"
 137          (float-time (time-subtract amin--before-user-init-time
 138                                     before-init-time)))
 139 #+end_src
 140
 141 Also, temporarily increase ~gc-cons-threshhold~ and
 142 ~gc-cons-percentage~ during startup to reduce garbage collection
 143 frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
 144 startup time as well.
 145
 146 #+begin_src emacs-lisp
 147 (defvar amin--gc-cons-threshold gc-cons-threshold)
 148 (defvar amin--gc-cons-percentage gc-cons-percentage)
 149 (defvar amin--file-name-handler-alist file-name-handler-alist)
 150 (setq gc-cons-threshold (* 400 1024 1024)  ; 400 MiB
 151       gc-cons-percentage 0.6
 152       file-name-handler-alist nil
 153       ;; sidesteps a bug when profiling with esup
 154       esup-child-profile-require-level 0)
 155 #+end_src
 156
 157 Of course, we'd like to set them back to their defaults once we're
 158 done initializing.
 159
 160 #+begin_src emacs-lisp
 161 (add-hook
 162  'after-init-hook
 163  (lambda ()
 164    (setq gc-cons-threshold amin--gc-cons-threshold
 165          gc-cons-percentage amin--gc-cons-percentage
 166          file-name-handler-alist amin--file-name-handler-alist)))
 167 #+end_src
 168
 169 Increase the number of lines kept in message logs (the =*Messages*=
 170 buffer).
 171
 172 #+begin_src emacs-lisp
 173 (setq message-log-max 20000)
 174 #+end_src
 175
 176 Optionally, we could suppress some byte compiler warnings like below,
 177 but for now I've decided to keep them enabled. See documentation for
 178 ~byte-compile-warnings~ for more details.
 179
 180 #+begin_src emacs-lisp
 181 ;; (setq byte-compile-warnings
 182 ;;       '(not free-vars unresolved noruntime lexical make-local))
 183 #+end_src
 184
 185 ** whoami
 186
 187 #+begin_src emacs-lisp

 189       user-mail-address "amin@aminb.org")
 190 #+end_src
 191
 192 ** Package management
 193
 194 *** No =package.el=
 195
 196 I can do all my package management things with Borg, and don't need
 197 Emacs' built-in =package.el=. Emacs 27 lets us disable =package.el= in
 198 the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
 199
 200 #+begin_src emacs-lisp :tangle early-init.el
 201 (setq package-enable-at-startup nil)
 202 #+end_src
 203
 204 But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
 205 right now), and even when released it'll be long before most distros
 206 ship in their repos, I'll still put the old workaround with the
 207 commented call to ~package-initialize~ here anyway.
 208
 209 #+begin_src emacs-lisp
 210 (setq package-enable-at-startup nil)
 211 ;; (package-initialize)
 212 #+end_src
 213
 214 *** Borg
 215
 216 #+begin_quote
 217 Assimilate Emacs packages as Git submodules
 218 #+end_quote
 219
 220 [[https://github.com/emacscollective/borg][Borg]] is at the heart of package management of my Emacs setup. In
 221 short, it creates a git submodule in =lib/= for each package, which
 222 can then be managed with the help of Magit or other tools.
 223
 224 #+begin_src emacs-lisp
 225 (setq user-init-file (or load-file-name buffer-file-name)
 226       user-emacs-directory (file-name-directory user-init-file))
 227 (add-to-list 'load-path
 228              (expand-file-name "lib/borg" user-emacs-directory))
 229 (require 'borg)
 230 (borg-initialize)
 231
 232 ;; (require 'borg-nix-shell)

 242    ("C-c b r" . borg-remove)))
 243 #+end_src
 244
 245 *** =use-package=
 246
 247 #+begin_quote
 248 A use-package declaration for simplifying your .emacs
 249 #+end_quote
 250
 251 [[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
 252 packages (in our case especially the latter) in a neatly organized way
 253 and without compromising on performance.
 254
 255 #+begin_src emacs-lisp
 256 (require 'use-package)
 257 (if nil  ; set to t when need to debug init
 258     (setq use-package-verbose t
 259           use-package-expand-minimally nil
 260           use-package-compute-statistics t
 261           debug-on-error t)
 262   (setq use-package-verbose nil
 263         use-package-expand-minimally t))
 264 #+end_src
 265
 266 *** Epkg
 267
 268 #+begin_quote
 269 Browse the Emacsmirror package database
 270 #+end_quote
 271
 272 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
 273 database, low-level functions for querying the database, and a
 274 =package.el=-like user interface for browsing the available packages.
 275
 276 #+begin_src emacs-lisp
 277 (use-package epkg
 278   :defer t
 279   :bind
 280   (("C-c b d" . epkg-describe-package)
 281    ("C-c b p" . epkg-list-packages)
 282    ("C-c b u" . epkg-update)))
 283 #+end_src
 284
 285 ** No littering in =~/.emacs.d=
 286
 287 #+begin_quote
 288 Help keeping ~/.emacs.d clean
 289 #+end_quote
 290
 291 By default, even for Emacs' built-in packages, the configuration files
 292 and persistent data are all over the place. Use =no-littering= to help
 293 contain the mess.
 294
 295 #+begin_src emacs-lisp
 296 (use-package no-littering
 297   :demand t
 298   :config
 299   (savehist-mode 1)
 300   (add-to-list 'savehist-additional-variables 'kill-ring)
 301   (save-place-mode 1)
 302   (setq auto-save-file-name-transforms
 303         `((".*" ,(no-littering-expand-var-file-name "auto-save/") t))))
 304 #+end_src
 305
 306 ** Custom file (=custom.el=)
 307
 308 I'm not planning on using the custom file much, but even so, I
 309 definitely don't want it mixing with =init.el=. So, here; let's give
 310 it it's own file. While at it, treat themes as safe.
 311
 312 #+begin_src emacs-lisp
 313 (use-package custom
 314   :no-require t
 315   :config
 316   (setq custom-file (no-littering-expand-etc-file-name "custom.el"))
 317   (when (file-exists-p custom-file)
 318     (load custom-file))
 319   (setf custom-safe-themes t))
 320 #+end_src
 321
 322 ** Secrets file
 323
 324 Load the secrets file if it exists, otherwise show a warning.
 325
 326 #+begin_src emacs-lisp
 327 (with-demoted-errors
 328     (load (no-littering-expand-etc-file-name "secrets")))
 329 #+end_src
 330
 331 ** Better =$PATH= handling
 332
 333 Let's use [[https://github.com/purcell/exec-path-from-shell][exec-path-from-shell]] to make Emacs use the =$PATH= as set up
 334 in my shell.
 335
 336 #+begin_src emacs-lisp
 337 (use-package exec-path-from-shell
 338   :defer 1
 339   :init
 340   (setq exec-path-from-shell-check-startup-files nil)
 341   :config

 343   ;; while we're at it, let's fix access to our running ssh-agent
 344   (exec-path-from-shell-copy-env "SSH_AGENT_PID")
 345   (exec-path-from-shell-copy-env "SSH_AUTH_SOCK"))
 346 #+end_src
 347
 348 ** Only one custom theme at a time
 349
 350 #+begin_src emacs-lisp
 351 ;; only one custom theme at a time
 352 ;;
 353 ;; (defadvice load-theme (before clear-previous-themes activate)

 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]].

 562 *** Startup screen and =*scratch*=
 563
 564 Firstly, let Emacs know that I'd like to have =*scratch*= as my
 565 startup buffer.
 566
 567 #+begin_src emacs-lisp
 568 (setq initial-buffer-choice t)

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

 574 #+begin_src emacs-lisp
 575 (setq initial-scratch-message nil)
 576 #+end_src
 577
 578 Also, let's use Text mode as the major mode, in case I want to
 579 customize it (=*scratch*='s default major mode, Fundamental mode,
 580 can't really be customized).
 581
 582 #+begin_src emacs-lisp
 583 (setq initial-major-mode 'text-mode)

 593 either.
