Getting started with ELPA
[edit | edit source]Installing the package manager
[edit | edit source]In Emacs 22 and above, the necessary modules are already present to install the package manager from a small bootstrap script. Simply copy and paste the following code in to a *scratch*
buffer and execute it with C-j
if you're in lisp interaction mode, C-x C-e
otherwise.
(let ((buffer (url-retrieve-synchronously
"http://tromey.com/elpa/package-install.el")))
(save-excursion
(set-buffer buffer)
(goto-char (point-min))
(re-search-forward "^$" nil 'move)
(eval-region (point) (point-max))
(kill-buffer (current-buffer))))
The package manager should install itself.
If you are using Emacs 21, you will need to have the wget utility available. Execute the following code:
(let ((buffer (get-buffer-create (generate-new-buffer-name " *Download*"))))
(save-excursion
(set-buffer buffer)
(shell-command "wget -q -O- http://tromey.com/elpa/package-install.el"
(current-buffer))
(eval-region (point-min) (point-max))
(kill-buffer (current-buffer))))
