php-ts-mode

A Tree-sitter based major mode for editing PHP codes.

Note

This package is based on Emacs 29's built-in treesit and c-ts-common features.
php-ts-mode has been tested with v0.21.1 of tree-sitter-php.

How to install

If you haven't installed Tree-sitter yet, please read How to Get Started with Tree-Sitter - Mastering Emacs. At this point, Tree-sitter may be too early for those who cannot compile and install it themselves. You will end up recompiling it with every future update of tree-sitter-php.

Package can be installed by running the following command.

M-x package-vc-install [RET] https://github.com/emacs-php/php-ts-mode

Configuration

Example configuration that you can put in your .emacs file

;; Enable variables highlighting
(customize-set-variable 'treesit-font-lock-level 4)

(add-hook 'php-ts-mode-hook (lambda ()
			      ;; Use spaces for indent
			      (setq-local indent-tabs-mode nil)))

Grammer installation

If you don't already have php-ts-mode installed, please evaluate the Lisp code below.

(add-to-list 'treesit-language-source-alist
             '(php "https://github.com/tree-sitter/tree-sitter-php" "master" "php/src"))

Running M-x treesit-install-language-grammar [RET] php will compile and install the latest tree-sitter-php.
