;;; init.el --- Emacs configuration file -*- lexical-binding: t; -*-
;; Author: Jessie Hildebrandt <jessieh.net>
;; Homepage: https://gitlab.com/jessieh/dot-emacs
;; Package-Requires: ((emacs "29.1"))
;; This file is not part of GNU Emacs.
;;; Commentary:
;; jessieh's (Mostly) Portable Emacs Config
;;
;; This configuration file was designed to work with Emacs 29.1, and will not
;; work with earlier versions. You should probably have native-comp enabled.
;;
;; This file will automatically generate an early-init.el file upon first run,
;; or if early-init.el is missing.
;;
;; All configuration efforts here are organized around the use of wrapped
;; `use-package' macros. The keyword order for any config entry should be:
;; - if/when/unless
;; - demand
;; - after
;; - requires
;; - defines/functions
;; - init/config
;; - custom/custom-faces
;; - commands
;; - mode/interpreter/hook
;; - bind/bind*/bind-keymap/bind-keymap*
;;
;; Custom functions and variables should generally be prefixed with "user/".
;; This prefix is purposely nonidiomatic so as to avoid collisions with any
;; package prefixes, inbuilt or otherwise.
