This is my Emacs configuration.  It's also a literate =org-mode= file.  Yeah, I'm a cool guy.

It's highly likely that the WTFPL is completely incompatible with the GPL, for what should be fairly obvious reasons.  To that, I say:

** Original init.el

This file replaces itself with the actual configuration when it's first run.  For easy installation, /this/ is the =init.el= file in git -- and you probably want to keep it that way.  To keep git from trying to update =init.el= when it's re-tangled, type this in the repo:

#+begin_src sh :tangle no
git update-index --assume-unchanged init.el
#+end_src

If, for some reason, you want to change this original file to be re-tracked, run this command:

#+begin_src sh :tangle no
git update-index --no-assume-unchanged init.el
#+end_src

Otherwise, here's the actual, original =init.el= that tangles this Org file and gets us going.

#+begin_src emacs-lisp :tangle no
  (require 'org)
  (find-file (concat user-emacs-directory "config.org"))
  (org-babel-tangle)
  (load-file (concat user-emacs-directory "early-init.el"))
  (load-file (concat user-emacs-directory "init.el"))
  (byte-compile-file (concat user-emacs-directory "init.el"))
#+end_src

*** TODO What I should do instead

Honestly, I should just change this "Original init.el" thing to a Makefile I can tangle in =config.org=, and track -- since it won't be overwritten or need any special =git= invocations to stop tracking it, I can edit it as I think about what would work best.  I could also maybe give it more of a "cross-platform" vibe by installing, say, =straight.el= in the Makefile on Windows.  One day ...

** Tangling

After our first tangle, each time we edit =config.org= we want to go ahead and re-tangle our config.  To that end, I've written ~acdw/tangle-init~, which automatically tangles =config.org=.

#+begin_src emacs-lisp
  (defun acdw/tangle-init ()
    "If the current buffer is `config.org', tangle it, then compile
  and load the resulting files."
    (when (equal (buffer-file-name)
                 (expand-file-name
                  (concat user-emacs-directory "config.org")))
      ;; Tangle and load init.el and early-init.el
      (require 'async)
      (async-start
       (lambda ()
         (let ((prog-mode-hook nil))
           (require 'org)
           (org-babel-tangle-file
            (expand-file-name
             (concat user-emacs-directory "config.org")))))
       (lambda (response)
         (acdw/load-init)
         (message "Tangled and loaded: %s" response)))))
#+end_src

Since I want to tangle every time I save =config.org=, I've added ~acdw/tangle-init~ to a hook.

#+begin_src emacs-lisp
  (add-hook 'after-save-hook #'acdw/tangle-init)
#+end_src

Finally, I want an easier way to load the generated init files than the old =M-x load-file RET ~/.config/emacs/init.el RET=.  So I've written ~acdw/load-init~ -- which also gets called at the end of the async part of ~acdw/tangle-init~.

#+begin_src emacs-lisp
  (defun acdw/load-init ()
    (interactive)
    (load-file (expand-file-name
                (concat user-emacs-directory "early-init.el")))
    (load-file (expand-file-name
                (concat user-emacs-directory "init.el"))))
#+end_src

** Miscellaneous bootstrappy stuff

*** Add directories to =load-path=

I also put lispy stuff in the =lisp/= subdirectory of my Emacs config, and under my SyncThing directory (for easy syncing ;P).

#+begin_src emacs-lisp
  (dolist (dir `(,(concat user-emacs-directory
                          (convert-standard-filename "lisp/"))
                 ,(expand-file-name "~/Sync/elisp/")))
    (add-to-list 'load-path dir))

#+end_src

*** TODO Require my secrets

While this is like, the /dumbest/ way to do this, it's what I'm doing right now.  I'm going to slap a TODO on here because I really should make it better -- like, =auth-sources= hooked into KeePassXC somehow... ?  Maybe follow [[https://www.billdietrich.me/Authentication.html?expandall=1#KeePassXCandSecretService][Bill Dietrich's setup]].

#+begin_src emacs-lisp
  (require 'acdw-secrets)
#+end_src

* Early initiation

Starting with version 27.1, Emacs loads =early-init.el= /before/ =init.el=, setting up early stuff like package management, etc.  Since I use an alternative package manager, I have to bootstrap it here.

Of course, I also want to set some really early-on settings here too, like =load-prefer-newer= -- why not?

#+begin_src emacs-lisp :tangle early-init.el :comments no
;; early-init.el -*- lexical-binding: t; no-byte-compile: t -*-
  (setq load-prefer-newer t)
#+end_src

** Increase the garbage collector

Let's try to speed startup times by increasing the garbage collector's threshold while running init.  Note the hook afterwards that restores it to a reasonable default.

#+begin_src emacs-lisp :tangle early-init.el
  (setq gc-cons-threshold (* 100 100 1000))

  (add-hook 'after-init-hook
            (lambda ()
              (setq gc-cons-threshold (* 100 100 100))
              (message "gc-cons-threshold restored to %S"
                       gc-cons-threshold)))
#+end_src

** Add more paths to the =exec-path=

When using Windows (at work), I need to use the PortableGit installation I've downloaded, since I don't have Admin privileges.

#+begin_src emacs-lisp :tangle early-init.el
  (when (eq system-type 'windows-nt)
    (dolist (path '("c:/Users/aduckworth/Downloads/emacs/bin"
                    "C:/Users/aduckworth/Downloads/PortableGit/bin"
                    "C:/Users/aduckworth/Downloads/PortableGit/usr/bin"))
      (add-to-list 'exec-path path)))
#+end_src

Elsewhere, I want to add a few more paths to the =exec-path= as well, since I store scripts in a couple of places at ~.

#+begin_src emacs-lisp :tangle early-init.el
  (dolist (path `(,(expand-file-name "bin"
                                     user-emacs-directory)
                  ,(expand-file-name "~/bin")
                  ,(expand-file-name "~/.local/bin")
                  ,(expand-file-name "~/Scripts")))
    (add-to-list 'exec-path path))
#+end_src

** Bootstrap [[https://github.com/raxod502/straight.el][straight.el]]

So far, this is the best package manager I've used.  It allows for /truly/ declarative package management (if I don't specify a package here, it doesn't get loaded), easy installation from pretty much any source (as long as it's got a git repo), /and/ it hooks into =use-package=!

The one annoying thing is that this bootstrap code doesn't work on Windows for some reason.  I'm too lazy to really try and figure out why, so when I need to bootstrap on Windows (pretty rare, TBH), I just [[https://github.com/raxod502/straight.el/archive/master.zip][download the master-branch zip file]] and extract it to =~/.emacs.d/straight/repos/=.

#+NAME: straight-bootstrap
#+begin_src emacs-lisp :tangle no
  (defvar bootstrap-version)
  (let ((bootstrap-file
         (expand-file-name "straight/repos/straight.el/bootstrap.el"
                           user-emacs-directory))
        (bootstrap-version 5))
    (unless (file-exists-p bootstrap-file)
      (with-current-buffer
          (url-retrieve-synchronously
           "https://raw.githubusercontent.com/raxod502/straight.el/develop/install.el"
           'silent 'inhibit-cookies)
        (goto-char (point-max))
        (eval-print-last-sexp)))
    (load bootstrap-file nil 'nomessage))
#+end_src

** ... but first: override the definition of straight.el to use the =develop= branch

For the KeePassXC bits later, I need the =develop= branch of straight, so I can pass a =:build= keyword.  I can do this, but I have to override the recipe for =straight.el= itself.  I do that here.  For more information, see [[https://github.com/raxod502/straight.el#overriding-recipes][the README]].

#+begin_src emacs-lisp :tangle early-init.el :noweb yes
  (setq straight-repository-branch "develop")

  <<straight-bootstrap>>
#+end_src

** Use [[https://jwiegley.github.io/use-package/][use-package]]

Like I said, =straight.el= hooks into =use-package= easily.  These two lines get the latter to use the former by default.

#+begin_src emacs-lisp :tangle early-init.el
  (setq straight-use-package-by-default t)
  (straight-use-package 'use-package)
#+end_src

** Keep =~/.emacs.d= tidy with [[https://github.com/emacscollective/no-littering][no-littering]]

I'll be honest -- I don't really notice this package.  But I think that's the point.  It keeps Emacs (and packages) from throwing files all over the place, so I have a clean =ls -l=.  Since I want to run this code as early as possible, I use the =straight-use-package= form instead of =use-package=.

#+begin_src emacs-lisp
  (straight-use-package 'no-littering)
  (require 'no-littering)
#+end_src

** Additional =use-package= keywords

*** [[https://github.com/a13/use-package-custom-update][:custom-update]]

The =:custom-update= keyword lets me do this:

#+begin_src emacs-lisp :tangle no
  (use-package package
    :custom-update
    (package-list '(1 2 3)))
#+end_src

instead of this:

#+begin_src emacs-lisp :tangle no
  (use-package package
    :config
    (add-to-list 'package-list '(1 2 3)))
#+end_src

It's not ... perfect, but it's kind of nice.

#+begin_src emacs-lisp
  (use-package use-package-custom-update
    :straight (use-package-custom-update
               :host github
               :repo "a13/use-package-custom-update"))
#+end_src

** Setup [[https://github.com/jwiegley/emacs-async][async]]

I thought this was included in Emacs at first, but it's not -- so we need to install and require it.

#+begin_src emacs-lisp :tangle early-init.el
  (straight-use-package 'async)
  (require 'async)
#+end_src

* Macros

** Customizing variables

I like =use-package= a lot, but I don't like using those shims you see in a lot of other Emacs configs where they use ~(use-package emacs)~ forms and stuff like that -- it just feels dirty.  Plus, =straight= gets confused about those packages sometimes.  So, since I'm actually /configuring/ Emacs in this Org file, which is nicely organized anyway, I can just set settings the old-school way.

Except.  Using =setq= is actually /not/ recommended any more, because =customize-set-variable= is more expressive and can include side-effects.  However, not all settings are customizable, /and/ =customize-set-variable= is like, way longer to type.  So I've decided to write a little macro (my first!) to copy =use-package='s =:custom= keyword, except ... /outside/ =use-package=.  I've called it =cuss=, because I have a terrible sense of humor.

#+begin_src emacs-lisp
  (defmacro cuss (var val)
    "Basically `use-package''s `:custom', but without using either."
    `(progn
       (funcall (or (get ',var 'custom-set) #'set-default)
                ',var ,val)))
#+end_src

* Theme: [[https://protesilaos.com/modus-themes/][Modus]]

Protesilaos Stavrou's /excellent/ theme pair.  At some point I'll probably write my own that's really minimal and does some funky stuff with faces, but until then, these really are the best I've used.

The big ~dolist~ form is from [[https://protesilaos.com/modus-themes/#h:a897b302-8e10-4a26-beab-3caaee1e1193][his documentation]]; it basically allows me to configure both themes before loading them.  I've tweaked his code a little to use =use-package=.

#+begin_src emacs-lisp
  (defmacro modus-themes-format-sexp (sexp &rest objects)
    `(eval (read (format ,(format "%S" sexp) ,@objects))))

  (dolist (theme '("operandi" "vivendi"))

** Theme changer

I also want to switch themes between night and day.

#+begin_src emacs-lisp
  (use-package theme-changer
    :custom
    (calendar-latitude 30.39)
    (calendar-longitude -91.83)
    :config
    (change-theme 'modus-operandi 'modus-vivendi))
#+end_src

* Simplify GUI

** Frame defaults

I want no toolbar, menubar, or scrollbars (ideally I'd have a vertical scrollbar if necessary, but apparently that's too much to ask the Emacs devs); and fringes and window dividers 2 pixels wide.

#+begin_src emacs-lisp
  (cuss default-frame-alist
        '((tool-bar-lines . 0)
          (menu-bar-lines . 0)
          (vertical-scroll-bars . nil)
          (horizontal-scroll-bars . nil)
          (right-divider-width . 2)
          (bottom-divider-width . 2)
          (left-fringe-width . 2)
          (right-fringe-width . 2)))
#+end_src

** Minibuffer window/frame defaults

Of course, on the minibuffer, I want to make sure there's no scrollbar -- even if I change my mind on =vertical-scroll-bars=, above.

#+begin_src emacs-lisp
  (cuss minibuffer-frame-alist
        '((width . 80)
          (height . 2)
          (vertical-scrollbars . nil)))

  (set-window-scroll-bars (minibuffer-window) nil nil)
#+end_src

** Remove unneeded GUI elements

The [[*Frame defaults][Frame Defaults]] section sets up the frame to be free of visual clutter, but /this/ section allows us to toggle that clutter's visibility easily, with one call to each of these functions.

#+begin_src emacs-lisp
  (menu-bar-mode -1)
  (tool-bar-mode -1)
  (scroll-bar-mode -1)
  (horizontal-scroll-bar-mode -1)
#+end_src

** Silky scrolling

from [[https://pizza.eli.li/wiki/emacs-config/][elioat]]

#+begin_src emacs-lisp
  (cuss scroll-margin 0)
  (cuss scroll-conservatively 10000)
  (cuss scroll-preserve-screen-position t)
  (cuss auto-window-vscroll nil)
#+end_src

** Tabs

I'm kind of getting into Emacs tabs -- but I like not showing the =tab-bar= when there's only one.

#+begin_src emacs-lisp
  (cuss tab-bar-show 1)

  (cuss tab-bar-tab-name-function 'tab-bar-tab-name-current-with-count)
#+end_src

** Word wrap and operate visually

=global-visual-line-mode= is one of those which, in my opinion, should be a default.  There's only one place I don't want to wrap words, and that's in =dired=, which I can set individually in its config.

#+begin_src emacs-lisp
  (global-visual-line-mode 1)
#+end_src

** Modeline

*** [[https://github.com/Malabarba/smart-mode-line][smart-mode-line]]

#+begin_src emacs-lisp
  (use-package smart-mode-line
    :custom
    (sml/no-confirm-load-theme t)
    :config
    (sml/setup))
#+end_src

*** [[https://github.com/Malabarba/rich-minority][rich-minority]]

=smart-mode-line= comes with =rich-minority= for taking care of minor modes in the modeline, so I'm not going to /also/ use =diminish= or anything.  However, =rich-minority= has kind of a hinky way of adding modes to the whitelist, so I had to write my own function to do so.

This confuration means that, by default, no minor modes are shown; if you want  a minor mode to be shown (like =word-count-mode= for me), call ~(rm/whitelist-add "REGEXP")~.

#+begin_src emacs-lisp
  (defun rm/whitelist-add (regexp)
    "Add a REGEXP to the whitelist for `rich-minority'."
    (if (listp 'rm--whitelist-regexps)
        (add-to-list 'rm--whitelist-regexps regexp)
      (setq rm--whitelist-regexps `(,regexp)))
    (setq rm-whitelist
          (mapconcat 'identity rm--whitelist-regexps "\\|")))

  (use-package rich-minority
    :config
    (rm/whitelist-add "^$"))
#+end_src

** Minibuffer

*** Keep cursor from going into the prompt

from [[http://ergoemacs.org/emacs/emacs_stop_cursor_enter_prompt.html][Ergo Emacs]].

#+begin_src emacs-lisp
  (cuss minibuffer-prompt-properties
        '(read-only t cursor-intangible t face minibuffer-prompt))
#+end_src

** Show =^L= as a line

I like using the form-feed character to separate pages, it turns out.  'Tis nice.  This package turns that character into a nice long line.

#+begin_src emacs-lisp
  (use-package form-feed
    :hook
    ((text-mode prog-mode) . form-feed-mode))
#+end_src

** Cursor

I want my cursor to be a bar in focused windows, but a hollow box in non-focused windows.

#+begin_src emacs-lisp
  (cuss cursor-type 'bar)
  (cuss cursor-in-non-selected-windows 'hollow)
#+end_src

* Typesetting

** Fonts
This is the best way I've come up with to specify a number of different fonts that apply depending on what's applied.  To be honest, I didn't really come up with the =font-candidate= function, though -- I got it from the [[https://www.emacswiki.org/emacs/SetFonts#toc11]["Testing if fonts are available?"]] section of the SetFonts page on EmacsWiki.

See [[https://emacs.stackexchange.com/questions/12351/when-to-call-find-font-if-launching-emacs-in-daemon-mode][this StackExchange question and answer]] for more information on why I have these font settings applied in a hook.

#+begin_src emacs-lisp
  (require 'cl)
  (defun font-candidate (&rest fonts)
    (loop for font in fonts
          when (find-font (font-spec :name font))
          return font))

  (defun acdw/setup-fonts ()
    "Setup fonts.  This has to happen after the frame is set up for
    the first time, so add it to `focus-in-hook'.  It removes
    itself."
    (interactive)
    (set-face-attribute 'default nil
                        :font
                        (font-candidate
                         "Libertinus Mono-11"
                         "Linux Libertine Mono O-11"
                         "Go Mono-11"
                         "Consolas-11"))

    (set-face-attribute 'fixed-pitch nil
                        :font
                        (font-candidate
                         "Libertinus Mono-11"
                         "Linux Libertine Mono O-11"
                         "Go Mono-11"
                         "Consolas-11"))

    (set-face-attribute 'variable-pitch nil
                        :font
                        (font-candidate
                         "Libertinus Serif-13"
                         "Linux Libertine O-12"
                         "Georgia-11"))

    (remove-hook 'focus-in-hook #'acdw/setup-fonts))

  (add-hook 'focus-in-hook #'acdw/setup-fonts)
#+end_src

** [[https://github.com/rolandwalker/unicode-fonts][unicode-fonts]]

This does something similar to the above code, but for the entirety of the Unicode field (I think).

#+begin_src emacs-lisp
  (use-package unicode-fonts
    :config
    (unicode-fonts-setup))
#+end_src

** Variable pitch faces

One reason I like the Modus themes so much is that they have /excellent/ support for variable-pitch faces, and mixing them with fixed-pitch faces in, say, Org Mode.  That means I can enable =variable-pitch-mode= in all my =text-mode=-derived buffers.

#+begin_src emacs-lisp
  (add-hook 'text-mode-hook #'variable-pitch-mode)
#+end_src

** Padding

This has been taken from [[https://lepisma.xyz/2017/10/28/ricing-org-mode/]["Ricing Org Mode"]] -- of course, I want the typographic niceties everywhere.

#+begin_src emacs-lisp
  (cuss line-spacing 0.1)
#+end_src

* Ease of use

** Startup

I want a minimal screen when I start Emacs.  Based on the beauty of configs like [[https://github.com/rougier/elegant-emacs][Nicolas Rougier's]] [[https://github.com/rougier/emacs-splash][splash screen]] [[https://github.com/rougier/nano-emacs][experiments]], I might try my hand at some kind of splash screen or dashboard -- but until then, a simple "Hi there!" will suffice 😎

#+begin_src emacs-lisp
  (cuss inhibit-startup-buffer-menu t)
  (cuss inhibit-startup-screen t)
  (cuss initial-buffer-choice t)
  (cuss initial-scratch-message ";; Hi there!\n")
#+end_src

** Completing-read niceties

=completing-read= is Emacs's selection-narrowing-slash-completion framework thing.  There's a bunch of packages for it, including =ido=, =icomplete=, =ivy=, and =helm=.  I use raxod52's =selectrum= and others, which /extend/ without /clobbering/ existing Emacs functionality.  Plus they seem to run faster, at least on Windows.

*** [[https://github.com/raxod502/selectrum][selectrum]]

=selectrum= is the basic /sorting and selecting items from a list/ functionality.  It's a drop-in replacement for =ido= or the really basic tab-completion Emacs has for, say, =find-file=.

#+begin_src emacs-lisp
  (use-package selectrum
    :config
    (selectrum-mode 1))
#+end_src

*** [[https://github.com/raxod502/prescient.el][prescient]]

=prescient= helps =selectrum= be more intelligent about sorting the candidates in a list -- it's in charge of the /filtering and sorting/ bit of =completing-read= and friends.  It has an algorithm that works well enough for me, though I keep hearing about [[https://github.com/oantolin/orderless][orderless]], enough to maybe try it as well sometime.

#+begin_src emacs-lisp
  (use-package prescient
    :config
    (prescient-persist-mode 1))

  (use-package selectrum-prescient
    :after (selectrum prescient)
    :config
    (selectrum-prescient-mode 1))
#+end_src

*** [[https://github.com/minad/cconsult][consult]]

=consult= is the newest package I have with this setup, and it kind of brings the =selectrum= experience up to par with =ivy='s -- it provides functions that list, say, recently used files /alongside/ buffers, allow you to search lines and go to them, etc.  It seems pretty nice so far.

By the way, the [[https://www.reddit.com/r/emacs/comments/k3c0u7][Reddit announcement thread for consult]] has a great comment by the author detailing [[https://www.reddit.com/r/emacs/comments/k3c0u7/consult_counselswiper_alternative_for/ge460z3/][the differences between different completing-read implementations]] that actually is what convinced me to try =consult=.

#+begin_src emacs-lisp
  (use-package consult
    :after (selectrum)
    :straight (consult
               :host github
               :repo "minad/consult")
    :bind (("C-x b" . consult-buffer)
           ("C-x 4 b" . consult-buffer-other-window)
           ("C-x 5 b" . consult-buffer-other-frame)
           ("M-g o" . consult-outline)
           ("M-g l" . consult-line)
           ("M-y" . consult-yank-pop)
           ("<help> a" . consult-apropos))
    :init
    (fset 'multi-occur #'consult-multi-occur)
    (consult-annotate-mode)
    :config
    (setf (alist-get 'execute-extended-command consult-annotate-alist)
          #'consult-annotate-command-full))
#+end_src

*** Ignore case

I don't like holding the Shift key if I can help it.

#+BEGIN_SRC emacs-lisp
  (cuss completion-ignore-case t)
  (cuss read-buffer-completion-ignore-case t)
  (cuss read-file-name-completion-ignore-case t)
#+END_SRC

** [[https://github.com/raxod502/ctrlf][ctrlf]]

The biggest reason I use this over the default functionality of =C-s= is that =ctrlf-forward-*= wraps the search around by default.

#+begin_src emacs-lisp
  (use-package ctrlf
    :custom
    (ctrlf-show-match-count-at-eol nil)
    :bind
    ("C-s" . ctrlf-forward-regexp)
    ("C-r" . ctrlf-backward-regexp)
    ("C-M-s" . ctrlf-forward-literal)
    ("C-M-r" . ctrlf-backward-literal)
    :config
    (ctrlf-mode 1))
#+end_src

** [[https://github.com/justbur/emacs-which-key][which-key]]

This package is really helpful for discovering functionality.  When I get more adept in my Emacs-fu, I might remove this.

#+begin_src emacs-lisp
  (use-package which-key
    :custom
    (which-key-popup-type 'minibuffer)
    (which-key-separator " ")
    (which-key-prefix-prefix "+")
    :config
    (which-key-mode))
#+end_src

** Miscellaneous settings

Maybe a better title for this section is *Other settings* -- or maybe I should put them somewhere else entirely.

*** Set =view-mode= when in a read-only file

=view-mode= gives easy-to-use keybindings, like Space for page-down, etc., which are nice to have when you can't edit the file anyway.

#+begin_src emacs-lisp
  (cuss view-read-only t)
#+end_src

*** Don't use dialog boxen

#+begin_src emacs-lisp
  (cuss use-dialog-box nil)
#+end_src

*** Enable all functions

By default, Emacs disables some commands, because NeWbIeS wOuLd GeT cOnFuSeD or some ish.  I just want to use the dang editor!

#+begin_src emacs-lisp
  (cuss disabled-command-function nil)
#+end_src

*** Shorter confirmations

Instead of making me type /yes/ or /no/, just let me hit the /y/ or /n/ key.

#+begin_src emacs-lisp
  (fset 'yes-or-no-p #'y-or-n-p)
#+end_src

*** Uniquify buffer names

This names buffers with the same basename (e.g., =~/.config/emacs/config.org= and =~/.emacs.d/config.org=) in a better way than the default (=config.org<1>=, etc).

#+begin_src emacs-lisp
  (require 'uniquify)
  (cuss uniquify-buffer-name-style 'forward)
#+end_src

*** Show buffer boundaries

These little L-shaped graphics at the top and bottom of buffers don't do anything, but I like 'em.

#+begin_src emacs-lisp
  (cuss indicate-buffer-boundaries
        '((top . right)
          (bottom . right)
          (t . nil)))
#+end_src

*** Hippie expand

At some point, will probably replace with [[https://company-mode.github.io/][company]].

#+begin_src emacs-lisp
  (global-set-key (kbd "M-/") 'hippie-expand)
#+end_src

*** "[[https://git.sr.ht/~technomancy/better-defaults/tree/master/better-defaults.el][better defaults]]"

Most of these come from technomancy's repo, linked above, just copy-pasted into here.

#+begin_src emacs-lisp
  (cuss save-interprogram-paste-before-kill t)
  (cuss apropos-do-all t)
  (cuss mouse-yank-at-point t)
  (cuss require-final-newline t)
  (cuss visible-bell (not (string= (system-name) "larry")))
  (cuss ediff-window-setup-function #'ediff-setup-windows-plain)
#+end_src

**** Zap-up-to-char, not zap-to-char

Similarly to =ibuffer=, this is a Better default™.

#+begin_src emacs-lisp
  (autoload 'zap-up-to-char "misc"
    "Kill up to, but not including, ARGth occurrence of CHAR." t)

  (global-set-key (kbd "M-z") 'zap-up-to-char)
#+end_src

**** iBuffer

A Better Default™ for =C-x C-b=.  I don't really use this, but everyone says it's worth it, so it's there.

#+begin_src emacs-lisp
  (global-set-key (kbd "C-x C-b") 'ibuffer)
#+end_src

*** So-long-mode

I figure, why not go ahead and make Emacs deal with really long lines better?  Can't hurt, right?

#+begin_src emacs-lisp
  (if (boundp 'global-so-long-mode)
      (global-so-long-mode))
#+end_src

*** Change =just-one-space= to =cycle-space=

I keep forgetting to actually /use/ this keybind (I think it's =M-SPC=?), but cycling spacing seems /way/ more useful than the default =just-one-space= function.

#+begin_src emacs-lisp
  (defun acdw/cycle-spacing-1 ()
    (interactive)
    (cycle-spacing -1))

  (bind-key [remap just-one-space] #'acdw/cycle-spacing-1)
#+end_src

* Persistence

Honestly, persistence across sessions was one of the best things about my well-tuned Vim setup.  Here's where I try to repeat that with Emacs.

** Auto-saves with [[https://github.com/bbatsov/super-save][super-save]]

The default =auto-save= functionality isn't ... /enough/ for me.  I want to /actually/ save the files, and I don't care about =#file#= stuff.  So ... I use this package.

#+begin_src emacs-lisp
  (use-package super-save
    :custom
    (auto-save-default nil)
    (super-save-exclue '(".gpg"))
    :config
    (super-save-mode 1))
#+end_src

** Backup files

To be honest, I probably don't need backup files at all.  At some point, I will probably delete this.

#+begin_src emacs-lisp
  (cuss backup-directory-alist
        `((".*" . ,(no-littering-expand-var-file-name "backup/"))))

  (cuss backup-by-copying 1)
  (cuss delete-old-versions -1)
  (cuss version-control t)
  (cuss vc-make-backup-files t)
#+end_src

** Recent files

Since I apparently /only/ edit my =config.org=, this is also probably not necessary -- I'd be better off just adding a ~(find-file (concat (user-emacs-directory "config.org")))~ at the end 😎

But until then, it's really nice to have a =recentf= list.

#+begin_src emacs-lisp
  (require 'recentf)

  (add-to-list 'recentf-exclude
               '(no-littering-var-directory
                 no-littering-etc-directory))

  (cuss recentf-max-menu-items 100)
  (cuss recentf-max-saved-items 100)

  (recentf-mode 1)
#+end_src

*** Easily navigate recent files

Now I'm going through this, I might not need this function any more.  I'll have to see how =consult= goes.

#+begin_src emacs-lisp
  (defun recentf-find-file ()
    "Find a recent file using `completing-read'."
    (interactive)
    (let ((file (completing-read "Recent file: " recentf-list nil t)))
      (when file
        (find-file file))))

  (bind-key "C-x C-r" #'recentf-find-file)
#+end_src

** Save places in visited files

#+begin_src emacs-lisp
  (require 'saveplace)

  (cuss save-place-file (no-littering-expand-var-file-name "places"))

  (cuss save-place-forget-unreadable-files
        (not (eq system-type 'windows-nt)))

  (save-place-mode 1)
#+end_src

** Save history

#+begin_src emacs-lisp
  (require 'savehist)

  (cuss savehist-additional-variables
        '(kill-ring
          search-ring
          regexp-search-ring))

  (cuss savehist-save-minibuffer-history t)

  (cuss history-length t)

  (cuss history-delete-duplicates t)

  (savehist-mode 1)
#+end_src

** Undo: [[https://gitlab.com/ideasman42/emacs-undo-fu-session][undo-fu-session]]

The other Killer Feature of Neovim when I used it was the perisistent undo.  I /think/ this works the same.  Honestly, undo is giving me a little grief recently; I need to look into it.

Note to self: if I /do/ switch away from =undo-fu=, look at [[https://github.com/emacsorphanage/undohist][undohist]].

#+begin_src emacs-lisp
  (use-package undo-fu-session
    :after (no-littering undo-fu)
    :custom
    (undo-fu-session-incompatible-files
     '("COMMIT_EDITMSG\\'"
       "/git-rebase-todo\\'"))
    (undo-fu-session-directory
     (no-littering-expand-var-file-name "undos/"))
    :config
    (global-undo-fu-session-mode 1))
#+end_src

* General editing

** File encoding

I just want to use UTF-8 everywhere, and end all files with UNIX line endings (=^J=, or =LF=).  Hell, even Windows Notepad correctly reads UNIX files nowadays (though of course you can't configure it to /save/ the files in UNIX-mode).  However, since Emacs is ~40 years old, it has a billion different ways to set encodings.  This is my best attempt at setting everything up how I want it.

I'm going to be honest -- most of this is a stab in the dark.

#+begin_src emacs-lisp
  (set-language-environment 'utf-8)
  (set-terminal-coding-system 'utf-8)
  (cuss locale-coding-system 'utf-8)
  (set-default-coding-systems 'utf-8)
  (set-selection-coding-system 'utf-8)
  (prefer-coding-system 'utf-8)

  ;; from https://www.emacswiki.org/emacs/EndOfLineTips

  (defun acdw/no-junk-please-were-unixish ()
    "Convert line endings to UNIX, dammit."
    (let ((coding-str (symbol-name buffer-file-coding-system)))
      (when (string-match "-\\(?:dos\\|mac\\)$" coding-str)
        (set-buffer-file-coding-system 'unix))))

  (add-hook 'find-file-hooks #'acdw/no-junk-please-were-unixish)
#+end_src

** [[https://gitlab.com/ideasman42/emacs-undo-fu][undo-fu]]

I've heard that Emacs' undo is weird, so here I am, trying to make it .... /less/ weird.  I keep forgetting I've installed this though, so I might uninstall it at some point.

#+begin_src emacs-lisp
  (use-package undo-fu

    ("C-/" . undo-fu-only-undo)
    ("C-?" . undo-fu-only-redo))

** Find/replace: [[https://github.com/benma/visual-regexp.el][visual-regexp]]

Another replacement for a Killer Feature in Neovim -- the ease of regexp find/replace was so wonderful, because I could easily see /what/ I'd be changing with a =%s= command, as well as /how/ it'd change.  This works... pretty similarly.  It could be a little better.

#+begin_src emacs-lisp
  (use-package visual-regexp
    :bind
    ("C-c r" . 'vr/replace)
    ("C-c q" . 'vr/query-replace))
#+end_src

** Visual editing

*** [[https://github.com/k-talo/volatile-highlights.el][volatile-highlights]]

Highlights text changed by certain operations.

#+begin_src emacs-lisp
  (use-package volatile-highlights
    :config
    (volatile-highlights-mode 1))
#+end_src

*** [[https://github.com/magnars/expand-region.el][expand-region]]

I don't use this a /ton/, but not because it's not useful -- I just forget it's there sometimes.

Basically, it allows you to do like a Kakoune-style incremental widening of the selection by semantic units.

 #+begin_src emacs-lisp
   (use-package expand-region
     :bind
     ("C-=" . er/expand-region)
     ("C-+" . er/contract-region))
 #+end_src

** Clean up white space on save

I'm not sure if I'll /keep/ this forever, because in combination with =super-save= I lose the final "thinking spaces" when I shift contexts to another window.

#+begin_src emacs-lisp
  (add-hook 'before-save-hook #'whitespace-cleanup)
  (add-hook 'before-save-hook #'delete-trailing-whitespace)
#+end_src

** Automatically revert a file to what it is on disk

Revert a buffer to reflect what's on disk if it's changed outside of Emacs.

* Writing

Configurations related to writing prose or verse.

** Word count: [[https://github.com/bnbeckwith/wc-mode][wc-mode]]

#+begin_src emacs-lisp

** [[https://github.com/joostkremers/visual-fill-column][visual-fill-column-mode]]

Center the text part of the frame within a =fill-column=-sized area in the frame as a whole.

#+begin_src emacs-lisp
  (use-package visual-fill-column
    :custom
    (split-window-preferred-function
     'visual-fill-column-split-window-sensibly)

#+end_src

*** Fix mouse bindings

In =visual-fill-column-mode=, mouse bindings on the margins don't work.  In fact, they don't work when /not/ in =visual-fill-column-mode=.  Let's bind those bindings.

#+begin_src emacs-lisp
  (dolist (vec '([left-margin wheel-down]
                 [right-margin wheel-down]))
    (bind-key vec 'scroll-down-command))

  (dolist (vec '([left-margin wheel-up]
                 [right-margin wheel-up]))
    (bind-key vec 'scroll-up-command))
#+end_src

=mouse-4= and =mouse-5= are also =wheel-up= and =wheel-down=, but they're reversed on *larry*, which uses "natural scrolling."  I don't know, I like it.

#+begin_src emacs-lisp
  (dolist (vec '([left-margin mouse-4]
                 [right-margin mouse-4]))
    (if (string= system-name "larry")
        (bind-key vec 'scroll-down-command)
      (bind-key vec 'scroll-up-command)))

  (dolist (vec '([left-margin mouse-5]
                 [right-margin mouse-5]))
    (if (string= system-name "larry")
        (bind-key vec 'scroll-up-command)
      (bind-key vec 'scroll-down-command)))
#+end_src

* Coding

The Other Thing Emacs is Good For.

** Formatting

*** Indenting: [[https://github.com/Malabarba/aggressive-indent-mode][aggressive-indent-mode]]

This automagically indents code on every change, as opposed to =electric-indent-mode=, which only does when I like, hit =RET= or whatever.  As such, I can turn =electric-indent-mode= off.

#+begin_src emacs-lisp
  (use-package aggressive-indent
    :init
    (electric-indent-mode -1)
    :config
    (global-aggressive-indent-mode 1))
#+end_src

*** [[https://github.com/jcsalomon/smarttabs][Smart tabs]]

I really want to like, use tabs all the time.  But I thought the =smart-tabs= package author made some good points about using tabs for semantic indentation, and spaces for the rest.  So.

#+begin_src emacs-lisp
  (use-package smart-tabs-mode
    :custom
    (whitespace-style
     '(face trailing tabs spaces lines newline
            empty indentation space-before-tab
            space-mark tab-mark newline-mark))
    :config
    (smart-tabs-insinuate 'c 'c++ 'javascript 'java 'ruby))
#+end_src

** Display

*** Prettify symbols mode

By default, I think =prettify-symbols-mode= only changes =lambda= to =λ=.  I should, at some point, add some prettified symbols.

#+begin_src emacs-lisp
  (add-hook 'prog-mode-hook #'prettify-symbols-mode)
#+end_src

*** Parentheses and frens

**** =show-paren-style=

A =mixed= =show-paren-style= means that, when both parentheses are visible, it just highlights them.  If one is /not/, though, it highlights the entire block.

#+begin_src emacs-lisp
  (cuss show-paren-style 'mixed)
  (show-paren-mode 1)
#+end_src

**** [[https://github.com/Fuco1/smartparens][smartparens]]

Automagically close pairs and stuff.  See also [[https://www.emacswiki.org/emacs/ParEdit][ParEdit]] -- maybe test that one?

#+begin_src emacs-lisp

#+end_src

*** Line numbers

I only want line numbers in =prog-mode=-derived modes.  In addition, apparently =linum-mode= works better in TUI, but is slower that =display-line-numbers=.  So I want to do some logic to see what to use.

#+begin_src emacs-lisp
  (defun acdw/enable-line-numbers ()
    "Enable line numbers, either through `display-line-numbers-mode'
  or through `linum-mode'."
    (if (and (fboundp 'display-line-numbers-mode)
             (display-graphic-p))
        (progn
          (display-line-numbers-mode 1)

** KeePassXC integration

I use KeePassXC, and I'd /like/ to use KeePassXC to get passwords and stuff at home.  So I'm trying this library out, since the secret-tool integration isn't built into the KeePassXC on Void.  If this doesn't work, looks like I'll have to become a packager 😜

* Appendix A: Scripts

** ~emacsdc~

Here's a wrapper script that'll start =emacs --daemon= if there isn't one, and then launche =emacsclient= on the arguments.  I'd recommend installing with ~ln -s emacsdc ~/.local/bin/~ or something.  Then you can set it as your ~$EDITOR~!

#+begin_src sh :shebang "#!/bin/sh" :tangle bin/emacsdc
  if ! emacsclient -nc "$@" 2>/dev/null; then
      emacs --daemon

** TODO export org to ODT on Windows

Windows doesn't have =zip= natively (though it /does/ have =curl= -- go figure!), so the ODT export for Org-mode won't work.  There /is/ a [[https://stackoverflow.com/questions/8625306/org-mode-zip-needed-how-to-over-come][StackOverflow discussion]] that mentions =p7zip= and a possible batch file, but I couldn't get that to work with a little testing.  It might need more work.

Something that /did/ work was downloading =zip.exe= from [[http://infozip.sourceforge.net/][Info-ZIP]], and placing it somewhere in =exec-path= -- though of course, /then/ you need =unzip.exe=, apparently in the same folder.  Git Portable ships with =unzip.exe=, for example, but even though it's in =exec-path=, org-export threw an error unless =zip= and =unzip= were in the /same/ folder.

So I might either (a) have to set up computers in this way when I use new ones, or (b) include both =zip.exe= and =unzip.exe= in /this/ Git repo, or ... something else.  A true quandry.

** TODO Fix slowdown on =C-x 8 RET=

I think it has something to do with the package =consult=, because it was /slow/, but not *this slow* before installing it.  Since it's slow anyway, I'm thinking I should figure out how to turn off =selectrum= when selecting a Unicode character anyway.  Maybe advice?

** TODO Figure out Org-mode TODOs

I need some standard once, and also some specific ones for this section.
