  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/raxod502/straight.el][straight.el]].  Over the years, I've taken inspiration from
  14 configurations of many different people.  Some of the configurations
  15 that I can remember 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 =straight.el=.  I also used Borg for a
  32 few months, but decided to try =straight.el= which allows direct use
  33 of the various package archives.

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

 102 ** Emacs initialization
 103
 104 I'd like to do a couple of measurements of Emacs' startup time. First,
 105 let's see how long Emacs takes to start up, before even loading
 106 =init.el=, i.e. =user-init-file=:
 107
 108 #+begin_src emacs-lisp
 109 (defvar a/before-user-init-time (current-time)
 110   "Value of `current-time' when Emacs begins loading `user-init-file'.")
 111 (message "Loading Emacs...done (%.3fs)"
 112          (float-time (time-subtract a/before-user-init-time
 113                                     before-init-time)))
 114 #+end_src
 115
 116 Also, temporarily increase ~gc-cons-threshhold~ and
 117 ~gc-cons-percentage~ during startup to reduce garbage collection
 118 frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
 119 startup time as well.
 120
 121 #+begin_src emacs-lisp
 122 (defvar a/gc-cons-threshold gc-cons-threshold)
 123 (defvar a/gc-cons-percentage gc-cons-percentage)
 124 (defvar a/file-name-handler-alist file-name-handler-alist)
 125 (setq gc-cons-threshold (* 400 1024 1024)  ; 400 MiB
 126       gc-cons-percentage 0.6
 127       file-name-handler-alist nil
 128       ;; sidesteps a bug when profiling with esup
 129       esup-child-profile-require-level 0)
 130 #+end_src
 131
 132 Of course, we'd like to set them back to their defaults once we're
 133 done initializing.
 134
 135 #+begin_src emacs-lisp
 136 (add-hook
 137  'after-init-hook
 138  (lambda ()
 139    (setq gc-cons-threshold a/gc-cons-threshold
 140          gc-cons-percentage a/gc-cons-percentage
 141          file-name-handler-alist a/file-name-handler-alist)))
 142 #+end_src
 143
 144 Increase the number of lines kept in message logs (the =*Messages*=
 145 buffer).
 146
 147 #+begin_src emacs-lisp
 148 (setq message-log-max 20000)
 149 #+end_src
 150
 151 Optionally, we could suppress some byte compiler warnings like below,
 152 but for now I've decided to keep them enabled. See documentation for
 153 ~byte-compile-warnings~ for more details.
 154
 155 #+begin_src emacs-lisp
 156 ;; (setq byte-compile-warnings
 157 ;;       '(not free-vars unresolved noruntime lexical make-local))

 162 #+begin_src emacs-lisp

 165 #+end_src
 166
 167 ** Package management
 168
 169 *** No =package.el=
 170
 171 I can do all my package management things with =straight.el=, and
 172 don't need Emacs' built-in =package.el=.  Emacs 27 lets us disable
 173 =package.el= in the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
 174
 175 #+begin_src emacs-lisp :tangle early-init.el
 176 (setq package-enable-at-startup nil)
 177 #+end_src
 178
 179 But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
 180 right now), and even when released it'll be long before most distros
 181 ship in their repos, I'll still put the old workaround with the
 182 commented call to ~package-initialize~ here anyway.
 183
 184 #+begin_src emacs-lisp :tangle no
 185 (setq package-enable-at-startup nil)
 186 ;; (package-initialize)
 187 #+end_src
 188
 189 Update: the above is not necessary, since =straight.el= automatically
 190 does that (and more).  See =straight-package-neutering-mode=.
 191
 192 *** =straight.el=
 193
 194 #+begin_quote
 195 Next-generation, purely functional package manager for the Emacs
 196 hacker.
 197 #+end_quote
 198
 199 =straight.el= allows me to have a fully reproducible Emacs setup.

 202 (setq straight-repository-branch "develop")
 203
 204 (defvar bootstrap-version)
 205 (let ((bootstrap-file
 206        (expand-file-name "straight/repos/straight.el/bootstrap.el" user-emacs-directory))
 207       (bootstrap-version 5))
 208   (unless (file-exists-p bootstrap-file)
 209     (with-current-buffer

 216
 217 (setq straight-use-package-by-default t)
 218 #+end_src
 219
 220 Since we enable =straight.el='s =straight-use-package-by-default=
 221 integration, we will define a =use-feature= for plain ole
 222 =use-package= without any of the =straight.el= stuff.
 223
 224 #+begin_src emacs-lisp
 225 (defmacro use-feature (name &rest args)
 226   "Like `use-package', but with `straight-use-package-by-default' disabled."
 227   (declare (indent defun))

 231 #+end_src

 237 #+end_quote
 238
 239 [[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
 240 packages (in our case especially the latter) in a neatly organized way
 241 and without compromising on performance.

 256 *** Epkg
 257
 258 #+begin_quote
 259 Browse the Emacsmirror package database
 260 #+end_quote
 261
 262 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
 263 database, low-level functions for querying the database, and a
 264 =package.el=-like user interface for browsing the available packages.
 265
 266 #+begin_src emacs-lisp
 267 (require 'bind-key)
 268 (use-package epkg

 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

 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-feature custom
 310   :no-require t
 311   :config
 312   (setq custom-file (no-littering-expand-etc-file-name "custom.el"))

 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

 342 #+end_src

 344 ** COMMENT Only one custom theme at a time

 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

 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.
