;;; Commentary:

;; This file contains code that must be executed early during Emacs'
;; startup for proper initialization, as described here:

;; Disable GC during init
(put 'gc-cons-percentage 'original-value-before-init gc-cons-percentage)
(put 'gc-cons-percentage 'value-during-init 0.6)
(defun restore-gc-cons-percentage-after-init ()

;; Color de fondo similar al theme para evitar que se vea blanco al iniciar
;; (add-to-list 'default-frame-alist '(background-color . "#282a36"))

;; Permitir solo la búsqueda de archivos a cargar en la config en case sensitive.
(setq auto-mode-case-fold nil)

;; Personalizaciones (Tedrían que ir en init-base, pero por optimización, las pongo acá)
(push '(menu-bar-lines . 0) default-frame-alist)   ; Quitar menús.
(push '(tool-bar-lines . 0) default-frame-alist)   ; Quitar toolbar.

;; Iniciar emacs maximizado
;; (add-to-list 'initial-frame-alist '(fullscreen . maximized)) ; frame inicial
;; (add-to-list 'default-frame-alist '(fullscreen . maximized)) ; Cada frame
(add-hook 'window-setup-hook 'toggle-frame-maximized t) ; Hacerlo mediante window-setup-hook (se maximiza al terminar de cargar la ventana)
(push '(ns-transparent-titlebar . t) default-frame-alist)

;; Resizing the Emacs frame can be a terribly expensive part of changing the
;; font. By inhibiting this, we easily halve startup times with fonts that are
;; larger than the system default.
