+#+TITLE: Emacs config
+#+AUTHOR: Case Duckworth
+#+BABEL: :cache yes
+#+PROPERTY: header-args :tangle init.el
+#+BANKRUPTCY_COUNT: 1
+
+* Preamble
+
+I wanted to write my Emacs configuration in [[https://orgmode.org][Org mode]] for a while, but never could quite figure out how.  Finally, I found [[https://github.com/larstvei/dot-emacs][Lars Tveito]]'s config, which does exactly what I want: =init.el= is small and simple, and replaced after the first run, and =init.org= is automatically tangled.  So I'm very excited.
+
+* Bootstrap
+
+/Check out Lars's config for the reasoning behind this./
+
+When this configuration is loaded for the first time, this ~init.el~ is loaded:
+
+#+BEGIN_SRC emacs-lisp :tangle no
+  ;; This file replaces itself with the actual configuration when first run.  To keep only this version in git, run this command:
+  ;; git update-index --assume-unchanged init.el
+  ;;
+  ;; If it needs to be changed, start tracking it again thusly:
+  ;; git update-index --no-assume-unchanged init.el
+
+  (require 'org)
+  (find-file (concat user-emacs-directory "init.org"))
+  (org-babel-tangle)
+  (load-file (concat user-emacs-directory "init.el"))
+  (byte-compile-file (concat user-emacs-directory "init.el"))
+#+END_SRC
+
+** Tangling
+After the first run, the above ~init.el~ will be replaced by the tangled stuff here.  However, when /this/ file is edited, we'll need to re-tangle everything.  However, nobody has time to do that manually with =C-c C-v t=, /every time/!  Luckily, Emacs is highly programmable.
+
+#+NAME: tangle-on-save
+#+BEGIN_SRC emacs-lisp :tangle no
+  (defun acdw/tangle-init ()
+    "If the current buffer is `init.org', the code blocks are tangled,
+    and the tangled file is compiled and loaded."
+    (when (equal (buffer-file-name)
+                 (expand-file-name (concat user-emacs-directory "init.org")))
+      ;; Avoid running hooks when tangling.
+      (let ((prog-mode-hook nil))
+        (org-babel-tangle)
+        (load-file (concat user-emacs-directory "early-init.el"))
+        (load-file (concat user-emacs-directory "init.el")))))
+
+  (add-hook 'after-save-hook #'acdw/tangle-init)
+#+END_SRC
+
+* Early initiation
+Emacs 27.1+ uses ~early-init.el~, which is evaluated before things like ~package.el~ and other stuff.  So I have a few settings in there.
+
+** Preamble
+Of course, first thing is the modeline.  After that, I set ~load-prefer-newer~ because, well, it /should/.
+#+BEGIN_SRC emacs-lisp :tangle early-init.el
+  ;;; early-init.el -*- lexical-binding: t; no-byte-compile: t -*-
+
+(setq load-prefer-newer t)
+#+END_SRC
+
+** Computers
+I have to set these constants before bootstrapping the package manager, since ~straight.el~ depends on Git, and at work, those are in a weird place.
+
+#+BEGIN_SRC emacs-lisp :tangle early-init.el
+  (defconst *acdw/at-work* (eq system-type 'windows-nt))
+  (defconst *acdw/at-larry* (string= (system-name) "larry"))
+  (defconst *acdw/at-bax* (string= (system-name) "bax"))
+  (defconst *acdw/at-home* (or *acdw/at-larry* *acdw/at-bax*))
+#+END_SRC
+
+** Package management
+ I've started using straight.el, which is great.  It grabs packages from git, and apparently will let me fork and edit them, which I'll probably get around to ... eventually.
+
+*** At work, Git's in a weird place
+#+BEGIN_SRC emacs-lisp :tangle early-init.el

+I don't know why, but for some reason the bootstrapping doesn't work on Windows.  I have to download the repo directly from github and put it in the right place (=~/.emacs.d/straight/repos/straight.el/=).

+* Macros
+** cuss
+I like ~use-package~,  but I don't like doing the weird "pseudo-package" stuff a lot of people do in their emacs configs.  Partially because I have to set ~:straight nil~ on a lot of built-in packages, but also because I think being /that/ obsessive over one interface through the whole config is ... I don't know, short-sighted?
+
+Either way, I /do/ like the ~:custom~ interface that ~use-package~ has, so I've re-implemented it in my own macro.  This way I don't have to worry about whether to ~setq~ or ~custom-set-variable~ or whatever.  Just ~cuss~!
+#+BEGIN_SRC emacs-lisp
+  (defmacro cuss (var val)
+    "Basically `use-package''s `:custom', but without either."
