Emacs/The Emacs Lisp Package Archive

The Emacs Lisp Package Archive, ELPA, makes it easy to download and install packages for emacs. The official site of ELPA is at http://tromey.com/elpa/. Getting started with ELPA Installing the package manager 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))))
