;;; acdw-fonts.el -- font setup -*- lexical-binding: t; coding: utf-8-unix -*-
;; Author: Case Duckworth <(rot13-string "npqj@npqj.arg")>
;; Created: Sometime during Covid-19, 2020
;; Keywords: configuration
;; URL: https://tildegit.org/acdw/emacs
;; This file is NOT part of GNU Emacs.
;; Everyone is permitted to do whatever with this software, without
;; limitation. This software comes without any warranty whatsoever,
;; but with two pieces of advice:
;; - Don't hurt yourself.
;; - Make good choices.
;;; Commentary:
;; This code is based heavily on (and in fact, until I am able to tweak it,
;; will be a copy of) Oliver Taylor's code, available here:
;; https://github.com/olivertaylor/olivertaylor.github.io
;; /blob/master/notes/20210324_emacs-optical-font-adjustment.org

"Font size, an integer, to be used for the `default' and `fixed-pitch' faces.
This value is multiplied by 10, so 12 becomes 120, in order to
comply with Emacs's `set-face-attribute' requirements.")
(defvar acdw-fonts/variable-size 12
"Font size, an integer, to be used for the `variable-pitch' face.
This value will be used to determine a relative (float) size
based on the default size. So if your default size is 12 and
your variable size is 14, the computed relative size will be
1.16.")
