emacs packages

For a specific package

Where to place the el file

After placing it, say myplugin.el to your ~/.emacs.d/ directory, add the following in your .emacs file:

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

Also, in many cases you would need the following instead of the second line:

(require 'myplugin)

for normal emacs packages 

add to init.el

(when (>= emacs-major-version 24)
  (require 'package)
  (add-to-list
   'package-archives
   '("melpa" . "http://melpa.org/packages/")
   t)

  (package-initialise))


In emacs type: MetaX list-packages.
