;;; terminal.el --- My cobbled together terminal -*- lexical-binding: t -*-
;; Author: William Carroll <wpcarro@gmail.com>
;;; Commentary:
;; My attempts at creating a sane Emacs terminal. Most of this work was created
;; before I discovered and fully adopted EXWM. Prior to this, the appeal of
;; having terminals inside of Emacs was appealing. So appealing in fact that I
;; was willing to work with inferior alternatives to non-Emacs terminals
;; (e.g. `ansi-term') instead of GUI alternatives like `alacritty` because the
;; productivity gains of having a terminal inside of Emacs might outweigh the
;; shortcomings of that particular terminal.
;;
;; All of this changed, however, after discovering EXWM, since I can embed X11
;; GUI windows inside of Emacs. Therefore, most of this module is maintained
;; for historical purposes.
;;
;; Benefits of `ansi-term':
;; - Color scheme remains consistent between Emacs and terminal.
;; - Same applies to my fonts.
;;
;; Downsides of `ansi-term':
;; - Paging feels sluggish with programs like `cat` and `less`.
;; - KBDs don't provide 100% coverage of what I expect from a terminal since
;; they were created to cooperate with Emacs.
