The auto-install code below will download
package.el and the
url package (if you need
it), will edit your
.emacs to initialize the
package manager on future invocations of Emacs, and will finally
initialize the package manager in your currently running Emacs.
There are two sets of instructions, depending on what version of
Emacs you are using.
If you are using Emacs 22, you already have the
url package, and you can eval this code:
(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))))If you don't know what "eval" means, it means that you should copy this into your
*scratch*buffer, move your cursor just after the final closing paren, and type C-j.
If you are running Emacs 21, you will need the external
wget utility. Eval this 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))))
If you have Emacs 21 but do not have
wget, then you
are on your own for now, sorry.
Once you have installed the package manager, type
M-x package-list-packages. Type
the package menu buffer to update the list of packages available
from the server. If you want a particular package, type
i next to its name to mark it for installation, and
x to download and install it.
Note that for some packages,
you to have an external
