;;
;; A comprehensive configuration example:
;;
;; (require 'doom-themes)
;;
;; ;; Global settings (defaults)
;; (setq doom-themes-enable-bold t ; if nil, bold is universally disabled
;; doom-themes-enable-italic t) ; if nil, italics is universally disabled
;;

;; ;; theme may have their own settings.
;; (load-theme 'doom-one t)
;;
;; ;; Enable flashing mode-line on errors
;; (doom-themes-visual-bell-config)
;;
;; ;; Enable custom neotree theme
;; (doom-themes-neotree-config) ; all-the-icons fonts must be installed!
