+
+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/emacscollective/borg][Borg]]. 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 Borg. For what it's worth, I briefly
+experimented with [[https://github.com/raxod502/straight.el][straight.el]], but found that it added about 2 seconds
+to my init time; which is unacceptable for me: I use Emacs as my
+window manager (via EXWM) and coming from bspwm, I'm too used to
+having fast startup times.
+
+** Installation
+
+To use this config for your Emacs, first you need to clone this repo,
+then bootstrap Borg, tell Borg to retrieve package submodules, and
+byte-compiled the packages. Something along these lines should work:
+
+#+begin_src sh :tangle no
+git clone https://github.com/aminb/dotfiles ~/.emacs.d
+cd ~/.emacs.d
+make bootstrap-borg
+make bootstrap
+make build
+#+end_src

+that =init.el= is an auto-generated file, not supposed to be edited),
+and provides some convenient key bindings for browsing through the

+
+** 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 amin--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 amin--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 amin--gc-cons-threshold gc-cons-threshold)
+(defvar amin--gc-cons-percentage gc-cons-percentage)
+(defvar amin--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 ()
+   (setq gc-cons-threshold amin--gc-cons-threshold
+         gc-cons-percentage amin--gc-cons-percentage
+         file-name-handler-alist amin--file-name-handler-alist)))
+#+end_src
+
+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
+;; (setq byte-compile-warnings
+;;       '(not free-vars unresolved noruntime lexical make-local))
+#+end_src

+** whoami
+
+#+begin_src emacs-lisp
+(setq user-full-name "Amin Bandali"
+      user-mail-address "amin@aminb.org")
+#+end_src
+
+** Package management
+
+*** No =package.el=
+
+I can do all my package management things with Borg, 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
+(setq package-enable-at-startup nil)
+;; (package-initialize)
+#+end_src
+
+*** Borg
+
+#+begin_quote
+Assimilate Emacs packages as Git submodules
+#+end_quote
+
+[[https://github.com/emacscollective/borg][Borg]] is at the heart of package management of my Emacs setup. In
+short, it creates a git submodule in =lib/= for each package, which
+can then be managed with the help of Magit or other tools.
+
+#+begin_src emacs-lisp
+(setq user-init-file (or load-file-name buffer-file-name)
+      user-emacs-directory (file-name-directory user-init-file))
+(add-to-list 'load-path
+             (expand-file-name "lib/borg" user-emacs-directory))
+(require 'borg)
+(borg-initialize)

+;; (require 'borg-nix-shell)

+   ("C-c b b" . borg-build)
+   ("C-c b c" . borg-clone)
+   ("C-c b r" . borg-remove)))
+#+end_src
+
+*** =use-package=
+
+#+begin_quote
+A use-package declaration for simplifying your .emacs
+#+end_quote
+
+[[https://github.com/jwiegley/use-package][use-package]] is an awesome utility for managing and configuring
+packages (in our case especially the latter) in a neatly organized way
+and without compromising on performance.
+
+#+begin_src emacs-lisp
+(require 'use-package)
+(if nil  ; set to t when need to debug init
+    (setq use-package-verbose t
+          use-package-expand-minimally nil

+          debug-on-error t)
+  (setq use-package-verbose nil
+        use-package-expand-minimally t))
+#+end_src
+
+*** Epkg
+
+#+begin_quote
+Browse the Emacsmirror package database
+#+end_quote
+
+Epkg provides access to a local copy of the [[https://emacsmirror.net][Emacsmirror]] package
+database, low-level functions for querying the database, and a
+=package.el=-like user interface for browsing the available packages.
+
+#+begin_src emacs-lisp
+(use-package epkg
+  :defer t
+  :bind
+  (("C-c b d" . epkg-describe-package)
+   ("C-c b p" . epkg-list-packages)
+   ("C-c b u" . epkg-update)))
+#+end_src
+
+** No littering in =~/.emacs.d=
+
+#+begin_quote
+Help keeping ~/.emacs.d clean
+#+end_quote
+
+By default, even for Emacs' built-in packages, the configuration files
+and persistent data are all over the place. Use =no-littering= to help
+contain the mess.
+
+#+begin_src emacs-lisp
+(use-package no-littering
+  :demand t
+  :config
+  (savehist-mode 1)
+  (add-to-list 'savehist-additional-variables 'kill-ring)
+  (save-place-mode 1)
+  (setq auto-save-file-name-transforms
+        `((".*" ,(no-littering-expand-var-file-name "auto-save/") t))))
+#+end_src
+
+** Custom file (=custom.el=)
+
+I'm not planning on using the custom file much, but even so, I
+definitely don't want it mixing with =init.el=. So, here; let's give
+it it's own file. While at it, treat themes as safe.
+
+#+begin_src emacs-lisp
+(use-package custom
+  :no-require t
+  :config
+  (setq custom-file (no-littering-expand-etc-file-name "custom.el"))
+  (when (file-exists-p custom-file)
+    (load custom-file))
+  (setf custom-safe-themes t))
+#+end_src
+
+** Secrets file
+
+Load the secrets file if it exists, otherwise show a warning.
+
+#+begin_src emacs-lisp
+(with-demoted-errors
+    (load (no-littering-expand-etc-file-name "secrets")))
+#+end_src
+
+** Better =$PATH= handling
+
+Let's use [[https://github.com/purcell/exec-path-from-shell][exec-path-from-shell]] to make Emacs use the =$PATH= as set up
+in my shell.
+
+#+begin_src emacs-lisp
+(use-package exec-path-from-shell
+  :defer 1
+  :init
+  (setq exec-path-from-shell-check-startup-files nil)
+  :config
+  (exec-path-from-shell-initialize)
+  ;; while we're at it, let's fix access to our running ssh-agent
+  (exec-path-from-shell-copy-env "SSH_AGENT_PID")
+  (exec-path-from-shell-copy-env "SSH_AUTH_SOCK"))
+#+end_src
+
+** Only one custom theme at a time
+
+#+begin_src emacs-lisp
+;; only one custom theme at a time
+;;
+;; (defadvice load-theme (before clear-previous-themes activate)
+;;   "Clear existing theme settings instead of layering them"
+;;   (mapc #'disable-theme custom-enabled-themes))
+#+end_src
+
+** Server
+
+Start server if not already running. Alternatively, can be done by
+issuing =emacs --daemon= in the terminal, which can be automated with
+a systemd service or using =brew services start emacs= on macOS. I use
+Emacs as my window manager (via EXWM), so I always start Emacs on
+login; so starting the server from inside Emacs is good enough for me.
+
+See [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Emacs-Server.html#Emacs-Server][Using Emacs as a Server]].
+
+#+begin_src emacs-lisp
+(use-package server
+  :defer 1
+  :config (or (server-running-p) (server-mode)))
+#+end_src
+
+** Unicode support
+
+Font stack with better unicode support, around =Ubuntu Mono= and
+=Hack=.
+
+#+begin_src emacs-lisp

+
+*** Time and battery in mode-line
+
+Enable displaying time and battery in the mode-line, since I'm not
+using the Xfce panel anymore. Also, I don't need to see the load
+average on a regular basis, so disable that.
+
+Note: using =i3status= on sway at the moment, so disabling this.

+#+end_src

+
+Might want to set the fringe to a smaller value, especially if using
+EXWM. I'm fine with the default for now.
+
+#+begin_src emacs-lisp
+;; (fringe-mode '(3 . 1))

+
+Emacs disables some commands by default that could persumably be
+confusing for novice users. Let's disable that.
+
+#+begin_src emacs-lisp
+(setq disabled-command-function nil)
+#+end_src
+
+*** Kill-ring
+
+Save what I copy into clipboard from other applications into Emacs'
+kill-ring, which would allow me to still be able to easily access it
+in case I kill (cut or copy) something else inside Emacs before
+yanking (pasting) what I'd originally intended to.
+
+#+begin_src emacs-lisp
+(setq save-interprogram-paste-before-kill t)
+#+end_src
+
+*** Minibuffer
+
+#+begin_src emacs-lisp
+(setq enable-recursive-minibuffers t
+      resize-mini-windows t)
+#+end_src
+
+*** Lazy-person-friendly yes/no prompts
+
+Lazy people would prefer to type fewer keystrokes, especially for yes
+or no questions. I'm lazy.
+
+#+begin_src emacs-lisp
+(defalias 'yes-or-no-p #'y-or-n-p)
+#+end_src
+
+*** Startup screen and =*scratch*=
+
+Firstly, let Emacs know that I'd like to have =*scratch*= as my
+startup buffer.
+
+#+begin_src emacs-lisp
+(setq initial-buffer-choice t)
+#+end_src
+
+Now let's customize the =*scratch*= buffer a bit. First off, I don't
+need the default hint.
+
+#+begin_src emacs-lisp
+(setq initial-scratch-message nil)
+#+end_src
+
+Also, let's use Text mode as the major mode, in case I want to
+customize it (=*scratch*='s default major mode, Fundamental mode,
+can't really be customized).
+
+#+begin_src emacs-lisp
+(setq initial-major-mode 'text-mode)
+#+end_src
+
+Inhibit the buffer list when more than 2 files are loaded.
+
+#+begin_src emacs-lisp

+I don't really need to see the startup screen or echo area message
+either.

+(advice-add #'display-startup-echo-area-message :override #'ignore)
+(setq inhibit-startup-screen t
+      inhibit-startup-echo-area-message user-login-name)
+#+end_src
+
+*** More useful frame titles
+
+Show either the file name or the buffer name (in case the buffer isn't
+visiting a file). Borrowed from Emacs Prelude.
+
+#+begin_src emacs-lisp
+(setq frame-title-format
+      '("" invocation-name " - "

+                 "%b"))))
+#+end_src
+
+*** Backups
+
+Emacs' default backup settings aren't that great. Let's use more
+sensible options. See documentation for the ~make-backup-file~
+variable.
+
+#+begin_src emacs-lisp
+(setq backup-by-copying t
+      version-control t
