rust-mode: A major Emacs mode for editing Rust source code

rust-mode makes editing Rust code with Emacs enjoyable.

Manual Installation

To install manually, check out this repository and add this to your .emacs file:

(add-to-list 'load-path "/path/to/rust-mode/")
(autoload 'rust-mode "rust-mode" nil t)
(add-to-list 'auto-mode-alist '("\\.rs\\'" . rust-mode))

This associates rust-mode with .rs files. To enable it explicitly, do M-x rust-mode.

package.el installation via MELPA

It can be more convenient to use Emacs's package manager to handle installation for you if you use many elisp libraries. If you have package.el but haven't added MELPA, the community package source, yet, add this to ~/.emacs.d/init.el:

(require 'package)
(add-to-list 'package-archives
             '("melpa" . "") t)

Then do this to load the package listing:

If you use a version of Emacs prior to 24 that doesn't include package.el, you can get it from here.

If you have an older ELPA package.el installed from, you should upgrade in order to support installation from multiple sources. The ELPA archive is deprecated and no longer accepting new packages, so the version there (1.7.1) is very outdated.

Install rust-mode

One you have package.el, you can install rust-mode or any other modes by choosing them from a list:

Now, to install packages, move your cursor to them and press i. This will mark the packages for installation. When you're done with marking, press x, and ELPA will install the packages for you (under ~/.emacs.d/elpa/).

Tests via ERT

The file rust-mode-tests.el contains tests that can be run via ERT. You can use to run them in batch mode, if you set the environment variable EMACS to a program that runs emacs.

To test it under emacs 23, which does not ship with ERT, download ert.el from and put it in a place where emacs can find it. (ERT has shipped with emacs since emacs 24.)
