#+TITLE: DOOM Emacs Configuration
This configuration of Emacs is highly opinionated.
* Basics
My identity. Used in a handful of places in Emacs to pre-populate authorship and such.

* User interface
** Fonts and themes
I change my default theme almost as often as the weather. I tend to revert back
to Doom One most of the time, but I like the Kaolin themes, as well as Nimbus
for it's retro charm. Nimbus just doesn't look great when I'm tired though.
#+BEGIN_SRC emacs-lisp
(setq doom-theme 'farmhouse-dark

#+END_SRC
** Borders
Barring the unfortunate end of X11 development and my eventual transition to
Wayland and sway, you can pry i3wm from my cold, dead hands. One problem, however
is that when you're trying your best to rice up i3, Emacs needs a padded
border.
#+BEGIN_SRC emacs-lisp

I use notmuch to read and write email from within Emacs.
Here, we'll plan to use w3m to parse HTML email. You do have to make sure w3m is
