;;; pkg/base.el --- summary -*- lexical-binding: t; -*-

;; Author: Maciej Szlosarczyk
;; Maintainer: Maciej Szlosarczyk
;; Version: 0.1-snapshot

;;; Commentary:

;; pkg/base defines basic packages and environment.

;;; Code:
(require 'icejam-keys-mode)

;;;;;;;; Other optimizations ;;;;;;;;;;;;;;;;;
;;;;;;;; Stolen from Doom Emacs. ;;;;;;;;;;;;;

;; Update emacs less often
(setopt idle-update-delay 1.0)

;; Disable bidirectional text rendering for a modest performance boost. I've set
;; this to `nil' in the past, but the `bidi-display-reordering's docs say that
;; is an undefined state and suggest this to be just as good:
(setq-default bidi-display-reordering 'left-to-right
              bidi-paragraph-direction 'left-to-right)

;; Reduce rendering/line scan work for Emacs by not rendering cursors or regions
;; in non-focused windows.
(setq-default cursor-in-non-selected-windows nil)
(setopt highlight-nonselected-windows nil)

;; More performant rapid scrolling over unfontified regions. May cause brief
;; spells of inaccurate syntax highlighting right after scrolling, which should
;; quickly self-correct.
