+
+This org file is my literate configuration for GNU Emacs, and is
+tangled to [[./init.el][init.el]]. Packages are installed and managed using
+[[https://github.com/raxod502/straight.el][straight.el]]. Over the years, I've taken inspiration from
+configurations of many different people. Some of the configurations
+that I can remember off the top of my head are:
+
+- [[https://github.com/dieggsy/dotfiles][dieggsy/dotfiles]]: literate Emacs and dotfiles configuration, uses
+ straight.el for managing packages
+- [[https://github.com/dakra/dmacs][dakra/dmacs]]: literate Emacs configuration, using Borg for managing
+ packages
+- [[http://pages.sachachua.com/.emacs.d/Sacha.html][Sacha Chua's literate Emacs configuration]]
+- [[https://github.com/dakrone/eos][dakrone/eos]]
+- Ryan Rix's [[http://doc.rix.si/cce/cce.html][Complete Computing Environment]] ([[http://doc.rix.si/projects/fsem.html][about cce]])
+- [[https://github.com/jwiegley/dot-emacs][jwiegley/dot-emacs]]: nix-based configuration
+- [[https://github.com/wasamasa/dotemacs][wasamasa/dotemacs]]
+- [[https://github.com/hlissner/doom-emacs][Doom Emacs]]
+
+I'd like to have a fully reproducible Emacs setup (part of the reason
+why I store my configuration in this repository) but unfortunately out
+of the box, that's not achievable with =package.el=, not currently
+anyway. So, I've opted to use =straight.el=. I also used Borg for a
+few months, but decided to try =straight.el= which allows direct use
+of the various package archives.
+
+** Installation
+:PROPERTIES:
+:CUSTOM_ID: installation
+:END:
+
+To use this config for your Emacs, first you need to clone this repo,
+then tangle =init.org= into =init.el=, and optionally byte-compile
+=init.el=.
+
+First, clone the repository and =cd= into it:
+
+#+begin_src sh :tangle no
+git clone https://git.sr.ht/~bandali/dotfiles ~/.emacs.d
+cd ~/.emacs.d
+#+end_src
+
+Then, decide if you would like to use a byte-compiled init file, and
+set the [[#byte-compiled-init][a/byte-compiled-init]] variable accordingly.
+
+Now, first tangle =init.org=, and only if you chose to have a
+byte-compiled init, build init as well:
+
+#+begin_src sh :tangle no
+make tangle-init
+make build-init
+#+end_src
+
+If you'd like to use a byte-compiled init, it's important that it be
+recompiled whenever =init.el= is generated from an updated =init.org=.
+Not only does my setup automatically and asynchronously tangle
+=init.org= to =init.el= every time you edit and save =init.org= in GNU
+Emacs, it will also invoke =make build-init= if you set
+=a/byte-compiled-init= to =t= above, so you wouldn't have to worry
+about manually tangling and compiling your init file whenever you
+change it. The output of the last byte-compilation in the current
+session is kept in a =*compilation*= buffer, which will automatically
+be displayed if compilation fails.

+that =init.el= is an auto-generated file, not supposed to be edited),

+** Byte-compiled init preference
+:PROPERTIES:
+:CUSTOM_ID: byte-compiled-init
+:END:
+
+If you would like a byte-compiled init file, set the following
+variable to ~t~, otherwise set it to ~nil~.
+
+#+begin_src emacs-lisp
+(defvar a/byte-compiled-init t
+ "If non-nil, byte-(re)compile init.el on successful tangles.")
+#+end_src
+
+You can click on [[#installation][Installation]] to jump back up there if you like :)
+
+** Emacs initialization
+
+I'd like to do a couple of measurements of Emacs' startup time. First,
+let's see how long Emacs takes to start up, before even loading
+=init.el=, i.e. =user-init-file=:
+
+#+begin_src emacs-lisp
+(defvar a/before-user-init-time (current-time)
+ "Value of `current-time' when Emacs begins loading `user-init-file'.")
+(message "Loading Emacs...done (%.3fs)"
+ (float-time (time-subtract a/before-user-init-time
+ before-init-time)))
+#+end_src
+
+Also, temporarily increase ~gc-cons-threshhold~ and
+~gc-cons-percentage~ during startup to reduce garbage collection
+frequency. Clearing the ~file-name-handler-alist~ seems to help reduce
+startup time as well.
+
+#+begin_src emacs-lisp
+(defvar a/gc-cons-threshold gc-cons-threshold)
+(defvar a/gc-cons-percentage gc-cons-percentage)
+(defvar a/file-name-handler-alist file-name-handler-alist)
+(setq gc-cons-threshold (* 400 1024 1024) ; 400 MiB
+ gc-cons-percentage 0.6
+ file-name-handler-alist nil
+ ;; sidesteps a bug when profiling with esup
+ esup-child-profile-require-level 0)
+#+end_src
+
+Of course, we'd like to set them back to their defaults once we're
+done initializing.
+
+#+begin_src emacs-lisp
+(add-hook
+ 'after-init-hook
+ (lambda ()

+Increase the number of lines kept in message logs (the =*Messages*=
+buffer).
+
+#+begin_src emacs-lisp
+(setq message-log-max 20000)
+#+end_src
+
+Optionally, we could suppress some byte compiler warnings like below,
+but for now I've decided to keep them enabled. See documentation for
+~byte-compile-warnings~ for more details.
+
+#+begin_src emacs-lisp

+#+end_src
+
+** Package management
+
+*** No =package.el=
+
+I can do all my package management things with =straight.el=, and
+don't need Emacs' built-in =package.el=. Emacs 27 lets us disable
+=package.el= in the =early-init-file= (see [[https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=24acb31c04b4048b85311d794e600ecd7ce60d3b][here]]).
+
+#+begin_src emacs-lisp :tangle early-init.el
+(setq package-enable-at-startup nil)
+#+end_src
+
+But since Emacs 27 isn't out yet (Emacs 26 is just around the corner
+right now), and even when released it'll be long before most distros
+ship in their repos, I'll still put the old workaround with the
+commented call to ~package-initialize~ here anyway.
+
+#+begin_src emacs-lisp :tangle no
+(setq package-enable-at-startup nil)
+;; (package-initialize)
+#+end_src
+
+Update: the above is not necessary, since =straight.el= automatically
+does that (and more). See =straight-package-neutering-mode=.
+
