;;; early-init.el --- Pre-init: GC ceiling and frame chrome -*- lexical-binding: t; -*-
|
|
;;; Commentary:
|
|
;; Runs before package.el initialises and first frame is drawn, the only place these take effect:
|
|
;; 1. Raising the GC ceiling, so the whole startup (package load + init.el)
|
|
;; runs without garbage-collection pauses.
|
|
;; 2. Removing the menu/tool/scroll bars via `default-frame-alist', so they
|
|
;; are never drawn — toggling the minor modes in init.el instead draws
|
|
;; them and then removes them, a visible flicker on launch.
|
|
;;
|
|
;; Nothing here may depend on a package: none are loaded yet.
|
|
;;; Code:
|
|
|
|
(startup-redirect-eln-cache (expand-file-name "var/eln-cache/" user-emacs-directory))
|
|
(setq package-user-dir (expand-file-name "var/elpa/" user-emacs-directory))
