  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
  65 file.

 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))
 158 #+end_src

 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=

 232
 233 Since we enable =straight.el='s =straight-use-package-by-default=
 234 integration, we will define a =use-feature= for plain ole
 235 =use-package= without any of the =straight.el= stuff.
 236
 237 #+begin_src emacs-lisp
 238 (defmacro use-feature (name &rest args)

 252 [[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring

 275 Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
 276 database, low-level functions for querying the database, and a
 277 =package.el=-like user interface for browsing the available packages.

 300 By default, even for Emacs' built-in packages, the configuration files
 301 and persistent data are all over the place. Use =no-littering= to help
 302 contain the mess.

 313 #+end_src
 314
 315 ** Custom file (=custom.el=)
 316
 317 I'm not planning on using the custom file much, but even so, I
 318 definitely don't want it mixing with =init.el=. So, here; let's give
 319 it it's own file. While at it, treat themes as safe.
 320

 340 ** Better =$PATH= handling
 341
 342 Let's use [[https://github.com/purcell/exec-path-from-shell][exec-path-from-shell]] to make Emacs use the =$PATH= as set up
 343 in my shell.

 364
 365 ** Server
 366
 367 Start server if not already running. Alternatively, can be done by
 368 issuing =emacs --daemon= in the terminal, which can be automated with
 369 a systemd service or using =brew services start emacs= on macOS. I use
 370 Emacs as my window manager (via EXWM), so I always start Emacs on
 371 login; so starting the server from inside Emacs is good enough for me.

 554 *** Startup screen and =*scratch*=
 555
 556 Firstly, let Emacs know that I'd like to have =*scratch*= as my
 557 startup buffer.
 558
 559 #+begin_src emacs-lisp
 560 (setq initial-buffer-choice t)
 561 #+end_src
 562
 563 Now let's customize the =*scratch*= buffer a bit. First off, I don't
 564 need the default hint.
 565
 566 #+begin_src emacs-lisp
 567 (setq initial-scratch-message nil)
 568 #+end_src
 569
 570 Also, let's use Text mode as the major mode, in case I want to
 571 customize it (=*scratch*='s default major mode, Fundamental mode,
 572 can't really be customized).
 573
 574 #+begin_src emacs-lisp
 575 (setq initial-major-mode 'text-mode)
 576 #+end_src
 577
 578 Inhibit the buffer list when more than 2 files are loaded.
 579
 580 #+begin_src emacs-lisp
 581 (setq inhibit-startup-buffer-menu t)
 582 #+end_src
 583
 584 I don't really need to see the startup screen or echo area message
 585 either.
