This configuration of Emacs is highly opinionated.

Basics

I don't actually know what this does … :thinking:

(add-to-list 'default-frame-alist '(inhibit-double-buffering . t))

My identity. Used in a handful of places in Emacs to prepopulate authorship and such.

(setq user-full-name "Colin Powell"
      user-mail-address "colin@unbl.ink")

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 Go Mono. But sometimes Emacs is sensitive to fonts and performance suffers, so we have Fira Mono to fall back on.

(setq doom-font (font-spec :family "FuraCode Nerd Font Mono" :size 12))
(setq doom-big-font (font-spec :family "FuraCode Nerd Font Mono" :size 17))
(setq doom-theme 'kaolin-aurora)

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.

;; Applies to current frame
(set-frame-parameter nil 'internal-border-width 20) ; 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 . 20))
;; Dash highlighting
(after! dash (dash-enable-font-lock))

Dash

I need to figure out what this doesr, hence the task below.

;; Dash highlighting
(after! dash (dash-enable-font-lock))

Weather

Wttrin is a pretty funny way to check weather. I like that you can copy and paste fun a ASCII representations of the day's weather. It's not terribly accurate though.

(setq wttrin-default-cities '("Castine, ME" "San Francisco" "Thessaloniki"))

Eglot

Eglot versus LSP? Until 27 lands stable, Eglot wins. I can actually read all it's source.

Music

Right now, just make sure I can connect to my local Mopidy server via MPDel.
