Configure Packaging

• package.el
• straight.el
• use-package

This is the package manager configuration for CCE: The Complete Computing Environment

I use MELPA and GNU ELPA to get my Emacs packages, as much as I can. It seems like a lot of folks are heading towards using straight.el or using another thing which pulls in packages directly from the sources, but I use these for now, unless I can't.

use-package

I want to use use-package for most packages which I currently install using this hand-built function, which I plan to only use for … installing use-package.

(setq cce/did-refresh-packages nil)
(defun install-pkg (pkg)
  (unless (package-installed-p pkg)
    (unless cce/did-refresh-packages
      (package-refresh-contents)
      (setq cce/did-refresh-packages t))
    (package-install pkg)))

(install-pkg 'use-package)
(require 'use-package)
(setq use-package-always-ensure t
      use-package-compute-statistics t)
