Installation via package.el

package.el is the built-in package manager in Emacs.

Alchemist.el is available on the two major package.el community maintained repos - MELPA Stable and MELPA.

You can install Alchemist with the following command:

M-x package-install [RET] alchemist [RET]

or by adding this bit of Emacs Lisp code to your Emacs initialization file (.emacs or init.el):

(unless (package-installed-p 'alchemist)
  (package-install 'alchemist))

If the installation doesn't work try refreshing the package list:

M-x package-refresh-contents [RET]

Keep in mind that MELPA packages are built automatically from the master branch, meaning bugs might creep in there from time to time. Never-the-less, installing from MELPA is the recommended way of obtaining Alchemist, as the master branch is normally quite stable and "stable" (tagged) builds are released somewhat infrequently.

With the most recent builds of Emacs, you can pin Alchemist to always use MELPA Stable by adding this to your Emacs initialization:

(add-to-list 'package-pinned-packages '(alchemist . "melpa-stable") t)

Via el-get

el-get is another popular package manager for Emacs. If you're an el-get user just do M-x el-get-install [RET] alchemist [RET].


You can install Alchemist manually by placing Alchemist on your load-path and require ing it. Many people favour the folder ~/.emacs.d/vendor.

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