Syntax highlighting and automatic indentation for the Zig programming language in Emacs. Requires Emacs 24.3 or later.

Simply install the zig-mode package via NonGNU ELPA or MELPA.

Alternatively, you can git clone the zig-mode repository somewhere (e.g. under your ~/.emacs.d/). zig-mode depends on reformatter for formatting buffers with zig fmt.

reformatter can be installed from MELPA or installed manually in a similar fashion to zig-mode. For this method, clone the reformatter git repository and add the path to the repository to your load-path.

Then add the following to your .emacs file:

(unless (version< emacs-version "24")
  (add-to-list 'load-path "~/path/to/your/zig-mode/")
  (autoload 'zig-mode "zig-mode" nil t)
  (add-to-list 'auto-mode-alist '("\\.zig\\'" . zig-mode)))

To run all unit tests with emacs, run:

./run_tests.sh

Note that Emacs 24.3 or later is required. If you need to specify which Emacs binary to use, you can do that by setting the EMACS environment variable, e.g.:

EMACS=/usr/bin/emacs24 ./run_tests.sh

zig-mode used to enable coloration of the compilation buffer using ANSI color codes, but this affected all compilation buffers, not just zig compilation output. If you want to restore this behavior, you can add the following snippet to your init.el or .emacs file:

(if (>= emacs-major-version 28)
    (add-hook 'compilation-filter-hook 'ansi-color-compilation-filter)
  (progn
    (defun colorize-compilation-buffer ()
      (let ((inhibit-read-only t))
        (ansi-color-apply-on-region compilation-filter-start (point))))
    (add-hook 'compilation-filter-hook 'colorize-compilation-buffer)))
