;;; Commentary:
;; Configuration file for ELPA. This configuration adds the following
;; archives:
;; - melpa: For all the latest packages.
;; - org: For the latest version of org-mode.
;; - oni: For my personal package configuration.
;; This configuration also sets up the proper variables for uploading
;; packages to my personal repository.
;;; Code:
(require 'gnutls)
(require 'package)
(require 'package-x)
;;;; If I let Emacs decide when to run ‘package-initialize’ it seems to do it
;;;; before adding my archives to the ‘package-archives’ variable. By disabling
;;;; the automatic call at startup and telling it to run it only on
;;;; ‘after-init-hook’ it’ll take my added package archives into account and I
;;;; can once again properly see what new packages have been added when I
;;;; refresh the package list.
;;;###autoload
(setq package-enable-at-startup nil)
;;; Disable any package archives to make sure that I can't install any packages
;;; through ELPA. I use Guix and should install packages through there.
