Use-Package

ID: org_gcr_2018-04-11T09-44-43-05-00_mara:55083825-349A-44D0-8026-2E652BE228A9

Configure use-package.

Sysop is likely to use this infrequently.

Start EMACS with this command:

emacs --debug-init --no-init-file --no-splash --background-color white --foreground-color black --vertical-scroll-bars --eval '(switch-to-buffer "*Messages*")' --name O2B-TEST --title O2B-TEST --load ~/src/help/.org-mode-package-management.emacs.el

(load-file "~/src/help/.org-mode-fundamentals.emacs.el")

Code requiring package-management can only follow this block.

Before ELPA, I used SVN to manage software packages for EMACS. After ELPA, I used ELPA-packages. Now this system uses MELPA and GNU. MELPA packages always have their issues fixed very quickly. GNU packages rarely have issues.

Initialize Package.

(package-initialize)
(add-to-list 'package-archives
             '("melpa" . "http://melpa.org/packages/") t)
(add-to-list 'package-archives
             '("gnu" . "http://elpa.gnu.org/packages/") t)

Use-Package is the most configurable and performant way to manage ELPA packages. Startup speed matters but not right now so don't use :defer.

Add the Use-Package distribution the load path.

(add-to-list 'load-path"~/src/use-package")

Load Use-Package and it's partner Diminish. Every package loaded before this point uses require. Every package loaded after this point uses use-package.

(eval-when-compile
  (require 'use-package))
(use-package diminish)

El-Get

ID: org_gcr_2018-04-11T09-44-43-05-00_mara:925A5891-AB13-4972-9C95-3B49B7D47885

EL-Get handles things that don't easily fit anywhere else.

Initialize EL-Get.

(add-to-list 'load-path "~/.emacs.d/el-get/el-get")

(unless (require 'el-get nil 'noerror)
  (with-current-buffer
      (url-retrieve-synchronously
       "https://raw.githubusercontent.com/dimitri/el-get/master/el-get-install.el")
    (goto-char (point-max))
    (eval-print-last-sexp)))
(setq help/el-get-packages nil)

Make it really easy to remind yourself and others what EMACS really stands for (in this case it is fun).

It is not good to flame people on the Internet. It is good to know what it is all about, and here is a way to see some examples of the absurdity of it all.

You might not always remember your shopping list, but we will remember it for you… though not necessarily for wholesale.

Do you remember when those great AT&T adds were on television and it changed your life and bought you a kitten? You will.

Ask el-get to make sure that those desired packages are installed.
