#+TITLE: DOOM Emacs Configuration
This configuration of Emacs is highly opinionated.
* Basics
I don't actually know what this does ... :thinking:
#+BEGIN_SRC emacs-lisp
(add-to-list 'default-frame-alist '(inhibit-double-buffering . t))
#+END_SRC
My identity. Used in a handful of places in Emacs to prepopulate authorship and such.
#+BEGIN_SRC emacs-lisp
(setq user-full-name "Colin Powell"
user-mail-address "colin@unbl.ink")
#+END_SRC
** TODO Figure out what `inhibit-double-buffering` does in Emacs
* 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.
I love [[https://blog.golang.org/go-fonts][Go Mono]]. But sometimes Emacs is sensitive
to fonts and performance suffers, so we have Fira Mono to fall back on.
#+BEGIN_SRC emacs-lisp
(setq doom-font (font-spec :family "FuraCode Nerd Font Mono" :size 12)
doom-big-font (font-spec :family "FuraCode Nerd Font Mono" :size 17)
doom-variable-pitch-font (font-spec :family "Liberation Serif" :size 16)
doom-serif-font (font-spec :family "Liberation Serif" :size 16)
doom-theme 'doom-one)
#+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
;; Applies to current frame
(set-frame-parameter nil 'internal-border-width 30) ; applies to the current frame
;; If we create new frames (via emacsclient) this will do the trick
(add-to-list 'default-frame-alist '(internal-border-width . 30))
;; Dash highlighting
(after! dash (dash-enable-font-lock))
#+END_SRC
** Dash
I need to figure out what this does, hence the task below.
#+BEGIN_SRC emacs-lisp
;; Dash highlighting
(after! dash (dash-enable-font-lock))
#+END_SRC
*** TODO Figure out what dash highlighting is all about
** Fringe
