#+PROPERTY: header-args :results silent
#+PROPERTY: header-args:emacs-lisp :lexical t :tangle ~/.emacs.el
This is a literate init file holding my Emacs configuration. It is
initially loaded by a [[file:.emacs.d/init.el::;;; -*- lexical-binding: t; -*-][bootstrap file]] that lives at ~/.emacs.d/init.el;
after the initial bootstrapping it writes itself to ~/.emacs.el. Since
~/.emacs.el takes priority over ~/.emacs.d/init.el, after the initial
bootstrapping process the tangled ~/.emacs.el file will get loaded
without needing to load the bootstrap file first.
* Prelude
Enables lexical binding for everything in init.el:
#+BEGIN_SRC emacs-lisp
;;; -*- lexical-binding: t; -*-
#+END_SRC
** Garbage collection
Some GC tweaks [[https://github.com/hlissner/doom-emacs/blob/develop/docs/faq.org#how-does-doom-start-up-so-quickly]["borrowed" from Doom emacs]].
Turn off GC during init and restore it afterwards:
#+BEGIN_SRC emacs-lisp
(setq gc-cons-threshold most-positive-fixnum
gc-cons-percentage 0.6)
(add-hook 'emacs-startup-hook
(lambda ()
(setq gc-cons-threshold 100000000
gc-cons-percentage 0.1)))
#+END_SRC
Also suppress GC for 1 second after the minibuffer is active to avoid stuttering autocompletion and other GC hangups:
#+BEGIN_SRC emacs-lisp
(defun defer-garbage-collection ()
(setq gc-cons-threshold most-positive-fixnum))
(defun restore-garbage-collection ()
(run-at-time
1 nil (lambda () (setq gc-cons-threshold 100000000))))

`exec-path-from-shell` uses Bash to set MANPATH, PATH, and exec-path from those defined in the user's shell config. This won't work on Windows.

* Autocompletion
There seems to be [[https://github.com/company-mode/company-mode/issues/68][some contention]] about whether autocomplete or company are better autocomplete packages. I'm going with company for now because the maintainer seems nicer...

** Buffer switch hooks
I want to be able to run code whenever I switch to a buffer running certain modes. The code to run is stored in a alist mapping mode names to lists of code to run (stored as a raw data structure to be eval'ed):
#+BEGIN_SRC emacs-lisp
(defvar buffer-mode-hooks '())
#+END_SRC
To add a new hook, push the code to run onto the correct list:
#+BEGIN_SRC emacs-lisp
(defun add-buffer-mode-hook (mode fn)
(if-let ((existing-entry (assoc mode buffer-mode-hooks)))
(push fn (cdr existing-entry))
(let ((new-entry `(,mode . (,fn))))
(push new-entry buffer-mode-hooks))))
#+END_SRC
Whenever the buffer changes, look up the major-mode to see if there is any code to run:
#+BEGIN_SRC emacs-lisp
(defun run-buffer-mode-hooks ()
(when-let ((entry (assoc major-mode buffer-mode-hooks)))
(dolist (fn (cdr entry))
(funcall fn))))
(add-hook 'buffer-list-update-hook #'run-buffer-mode-hooks)
#+END_SRC

#+END_SRC
** Miscellaneous
#+BEGIN_SRC emacs-lisp

#+END_SRC
* Dropbox
I put lots of stuff in Dropbox, but the actual folder location differs on my different computers. This function resolves to the Dropbox directory:
#+BEGIN_SRC emacs-lisp
(defun get-dropbox-directory ()

(expand-file-name "~/Dropbox (Personal)"))

#+END_SRC
Load up libraries from Dropbox, if there are any:
#+BEGIN_SRC emacs-lisp

#+END_SRC
* Init File
A function to reload my init file. It reloads the major mode after the init file is loaded to rebind keymappings.
#+BEGIN_SRC emacs-lisp

Mu4e uses shr to render HTML emails. Unfortunately the shr function
that sets faces in the rendered document has a bug: it appends the shr
faces to the existing face-list, rather than prepending the shr
face. This means that e.g. links don't actually get rendered correctly
if there is some non-link face already on the text. The fix:
