hack-mode is an Emacs major mode for editing Hack code.
hack-mode includes extensive, precise syntax highlighting:
- Comment highlighting (additionally highlighting special comments
like
strict,HH_FIXME) - Keyword highlighting (case insensitive where appropriate)
- String (
'foo',"foo",<<<FOOand<<<'FOO') highlighting, including interpolation - XHP support
It also provides indentation, integration with hackfmt and
parenthesis match highlighting.
Install from MELPA, or load this package into your elisp load-path.
After installation, hack-mode will automatically run on .hack,
.hck and .hhi files.
It will also run on .php files, but php-mode will take precedence
if installed. If you want hack-mode to take precedence, use the
following:
(add-to-list 'auto-mode-alist '("\\.php\\'" . hack-mode))hack-mode provides hack-format-buffer to run hackfmt on the
whole file. If you'd like this automatically run on save, add it to
your hooks:
(add-hook 'hack-mode-hook #'hack-enable-format-on-save)We recommend using hack-mode with the following minor-modes:
(add-hook 'hack-mode-hook #'lsp)
(add-hook 'hack-mode-hook #'flycheck-mode)
(add-hook 'hack-mode-hook #'company-mode)hack-mode is licensed under the GNU General Public License v3.0.
