  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://git.sr.ht/~bandali/dotfiles ~/.emacs.d
  45 cd ~/.emacs.d
  46 make bootstrap-borg
  47 make bootstrap
  48 #+end_src

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

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

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

 238 *** =use-package=
 239
 240 #+begin_quote
 241 A use-package declaration for simplifying your .emacs
 242 #+end_quote
 243
 244 [[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
 245 packages (in our case especially the latter) in a neatly organized way
 246 and without compromising on performance.
 247

 249 (require 'use-package)

 261 *** Epkg
 262
 263 #+begin_quote
 264 Browse the Emacsmirror package database
 265 #+end_quote
 266
 267 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
 268 database, low-level functions for querying the database, and a
 269 =package.el=-like user interface for browsing the available packages.
 270
 271 #+begin_src emacs-lisp
 272 (use-package epkg
 273   :bind
 274   (("C-c b d" . epkg-describe-package)

 284 ** No littering in =~/.emacs.d=
 285
 286 #+begin_quote

 288 #+end_quote
 289
 290 By default, even for Emacs' built-in packages, the configuration files
 291 and persistent data are all over the place. Use =no-littering= to help
 292 contain the mess.
 293
 294 #+begin_src emacs-lisp
 295 (use-package no-littering

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

 319 #+end_src
 320
 321 ** Secrets file

 328 #+end_src
 329
 330 ** Better =$PATH= handling
 331
 332 Let's use [[https://github.com/purcell/exec-path-from-shell][exec-path-from-shell]] to make Emacs use the =$PATH= as set up
 333 in my shell.
 334

 345 #+end_src

 347 ** COMMENT Only one custom theme at a time
 348
 349 #+begin_src emacs-lisp
 350 (defadvice load-theme (before clear-previous-themes activate)

 353 #+end_src
 354
 355 ** Server
 356
 357 Start server if not already running. Alternatively, can be done by
 358 issuing =emacs --daemon= in the terminal, which can be automated with
 359 a systemd service or using =brew services start emacs= on macOS. I use
 360 Emacs as my window manager (via EXWM), so I always start Emacs on
 361 login; so starting the server from inside Emacs is good enough for me.
 362

 544 *** Startup screen and =*scratch*=
 545
 546 Firstly, let Emacs know that I'd like to have =*scratch*= as my
 547 startup buffer.
 548
 549 #+begin_src emacs-lisp
 550 (setq initial-buffer-choice t)
 551 #+end_src
 552
 553 Now let's customize the =*scratch*= buffer a bit. First off, I don't
 554 need the default hint.
 555
 556 #+begin_src emacs-lisp
 557 (setq initial-scratch-message nil)
 558 #+end_src
 559
 560 Also, let's use Text mode as the major mode, in case I want to
 561 customize it (=*scratch*='s default major mode, Fundamental mode,
 562 can't really be customized).
 563
 564 #+begin_src emacs-lisp
 565 (setq initial-major-mode 'text-mode)
 566 #+end_src
 567
 568 Inhibit the buffer list when more than 2 files are loaded.
 569
 570 #+begin_src emacs-lisp
 571 (setq inhibit-startup-buffer-menu t)
 572 #+end_src
 573
 574 I don't really need to see the startup screen or echo area message
 575 either.
