  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
  49 #+end_src

  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
  81 file.

 118 ** Emacs initialization
 119
 120 I'd like to do a couple of measurements of Emacs' startup time. First,
 121 let's see how long Emacs takes to start up, before even loading
 122 =init.el=, i.e. =user-init-file=:
 123
 124 #+begin_src emacs-lisp
 125 (defvar a/before-user-init-time (current-time)
 126   "Value of `current-time' when Emacs begins loading `user-init-file'.")
 127 (message "Loading Emacs...done (%.3fs)"
 128          (float-time (time-subtract a/before-user-init-time
 129                                     before-init-time)))
 130 #+end_src
 131
 132 Also, temporarily increase ~gc-cons-threshhold~ and
 133 ~gc-cons-percentage~ during startup to reduce garbage collection
 134 frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
 135 startup time as well.
 136
 137 #+begin_src emacs-lisp
 138 (defvar a/gc-cons-threshold gc-cons-threshold)
 139 (defvar a/gc-cons-percentage gc-cons-percentage)
 140 (defvar a/file-name-handler-alist file-name-handler-alist)
 141 (setq gc-cons-threshold (* 400 1024 1024)  ; 400 MiB
 142       gc-cons-percentage 0.6
 143       file-name-handler-alist nil
 144       ;; sidesteps a bug when profiling with esup
 145       esup-child-profile-require-level 0)
 146 #+end_src
 147
 148 Of course, we'd like to set them back to their defaults once we're
 149 done initializing.
 150
 151 #+begin_src emacs-lisp
 152 (add-hook
 153  'after-init-hook
 154  (lambda ()
 155    (setq gc-cons-threshold a/gc-cons-threshold
 156          gc-cons-percentage a/gc-cons-percentage
 157          file-name-handler-alist a/file-name-handler-alist)))
 158 #+end_src
 159
 160 Increase the number of lines kept in message logs (the =*Messages*=
 161 buffer).
 162
 163 #+begin_src emacs-lisp
 164 (setq message-log-max 20000)
 165 #+end_src
 166
 167 Optionally, we could suppress some byte compiler warnings like below,
 168 but for now I've decided to keep them enabled. See documentation for
 169 ~byte-compile-warnings~ for more details.
 170
 171 #+begin_src emacs-lisp
 172 ;; (setq byte-compile-warnings
 173 ;;       '(not free-vars unresolved noruntime lexical make-local))
 174 #+end_src
 175

 181 #+end_src
 182
 183 ** Package management
 184
 185 *** No =package.el=
 186
 187 I can do all my package management things with Borg, and don't need
 188 Emacs' built-in =package.el=. Emacs 27 lets us disable =package.el= in
 189 the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
 190
 191 #+begin_src emacs-lisp :tangle early-init.el
 192 (setq package-enable-at-startup nil)
 193 #+end_src
 194
 195 But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
 196 right now), and even when released it'll be long before most distros
 197 ship in their repos, I'll still put the old workaround with the
 198 commented call to ~package-initialize~ here anyway.
 199
 200 #+begin_src emacs-lisp
 201 (setq package-enable-at-startup nil)
 202 ;; (package-initialize)
 203 #+end_src
 204
 205 *** Borg
 206
 207 #+begin_quote
 208 Assimilate Emacs packages as Git submodules
 209 #+end_quote
 210
 211 [[https://github.com/emacscollective/borg][Borg]] is at the heart of package management of my Emacs setup. In
 212 short, it creates a git submodule in =lib/= for each package, which
 213 can then be managed with the help of Magit or other tools.
 214
 215 #+begin_src emacs-lisp
 216 (setq user-init-file (or load-file-name buffer-file-name)
 217       user-emacs-directory (file-name-directory user-init-file))

 237
 238 #+begin_quote
 239 A use-package declaration for simplifying your .emacs
 240 #+end_quote
 241
 242 [[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
 243 packages (in our case especially the latter) in a neatly organized way
 244 and without compromising on performance.
 245
 246 #+begin_src emacs-lisp
 247 (require 'use-package)
 248 (if nil  ; set to t when need to debug init
 249     (setq use-package-verbose t

 256
 257 *** Epkg
 258
 259 #+begin_quote
 260 Browse the Emacsmirror package database
 261 #+end_quote
 262
 263 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
 264 database, low-level functions for querying the database, and a
 265 =package.el=-like user interface for browsing the available packages.
 266
 267 #+begin_src emacs-lisp
 268 (use-package epkg
 269   :defer t
 270   :bind
 271   (("C-c b d" . epkg-describe-package)
 272    ("C-c b p" . epkg-list-packages)
 273    ("C-c b u" . epkg-update))
 274   :config
 275   (eval-when-compile (defvar ivy-initial-inputs-alist))
 276   (with-eval-after-load 'ivy

 279 #+end_src

 281 ** No littering in =~/.emacs.d=
 282
 283 #+begin_quote
 284 Help keeping ~/.emacs.d clean
 285 #+end_quote
 286
 287 By default, even for Emacs' built-in packages, the configuration files
 288 and persistent data are all over the place. Use =no-littering= to help
 289 contain the mess.
 290
 291 #+begin_src emacs-lisp
 292 (use-package no-littering
 293   :demand t
 294   :config

 300 #+end_src
 301
 302 ** Custom file (=custom.el=)
 303
 304 I'm not planning on using the custom file much, but even so, I
 305 definitely don't want it mixing with =init.el=. So, here; let's give
 306 it it's own file. While at it, treat themes as safe.
 307
 308 #+begin_src emacs-lisp
 309 (use-package custom
 310   :no-require t
 311   :config
 312   (setq custom-file (no-littering-expand-etc-file-name "custom.el"))
 313   (when (file-exists-p custom-file)
 314     (load custom-file))
 315   (setf custom-safe-themes t))
 316 #+end_src
 317
 318 ** Secrets file

 323 (with-demoted-errors
 324     (load (no-littering-expand-etc-file-name "secrets")))
 325 #+end_src
 326
 327 ** Better =$PATH= handling
 328
 329 Let's use [[https://github.com/purcell/exec-path-from-shell][exec-path-from-shell]] to make Emacs use the =$PATH= as set up
 330 in my shell.
 331
 332 #+begin_src emacs-lisp
 333 (use-package exec-path-from-shell
 334   :defer 1

 339   ;; while we're at it, let's fix access to our running ssh-agent
 340   (exec-path-from-shell-copy-env "SSH_AGENT_PID")
 341   (exec-path-from-shell-copy-env "SSH_AUTH_SOCK"))
 342 #+end_src
 343
 344 ** COMMENT Only one custom theme at a time
 345
 346 #+begin_src emacs-lisp
 347 (defadvice load-theme (before clear-previous-themes activate)
 348   "Clear existing theme settings instead of layering them"
 349   (mapc #'disable-theme custom-enabled-themes))
 350 #+end_src
 351
 352 ** Server
 353
 354 Start server if not already running. Alternatively, can be done by
 355 issuing =emacs --daemon= in the terminal, which can be automated with
 356 a systemd service or using =brew services start emacs= on macOS. I use
 357 Emacs as my window manager (via EXWM), so I always start Emacs on
 358 login; so starting the server from inside Emacs is good enough for me.
 359

 475 *** Time and battery in mode-line
 476
 477 Enable displaying time and battery in the mode-line, since I'm not
 478 using the Xfce panel anymore. Also, I don't need to see the load
 479 average on a regular basis, so disable that.
 480

 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
 549
 550 Now let's customize the =*scratch*= buffer a bit. First off, I don't
 551 need the default hint.
 552
 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
 562 (setq initial-major-mode 'text-mode)
 563 #+end_src
 564
 565 Inhibit the buffer list when more than 2 files are loaded.
 566
 567 #+begin_src emacs-lisp
 568 (setq inhibit-startup-buffer-menu t)
 569 #+end_src
 570
 571 I don't really need to see the startup screen or echo area message
 572 either.
 573
 574 #+begin_src emacs-lisp
 575 (advice-add #'display-startup-echo-area-message :override #'ignore)
