Simple drupal-mode.el

This is a simple major mode for editing PHP files according to Drupal's coding standard. It extends php-mode and provides basic indentation. However, the (advanced) Drupal mode maintained by arnested is much better.

Save the following code to the file ~/.emacs.d/drupal-mode.el

;;; drupal-mode.el --- major mode for Drupal coding

;;;###autoload
(define-derived-mode drupal-mode php-mode "Drupal"
  "Major mode for Drupal coding.\n\n\\{drupal-mode-map}"
  (setq c-basic-offset 2)
  (setq indent-tabs-mode nil)
  (setq fill-column 78)
  (setq show-trailing-whitespace t)
  (add-hook 'before-save-hook 'delete-trailing-whitespace)
  (c-set-offset 'case-label '+)
  (c-set-offset 'arglist-close 0)
  (c-set-offset 'arglist-intro '+) ; for FAPI arrays and DBTNG
  (c-set-offset 'arglist-cont-nonempty 'c-lineup-math) ; for DBTNG fields and values
  (run-mode-hooks 'drupal-mode-hook)
)
(provide 'drupal-mode)

Then, in your ~/.emacs setup file associations. This example opens Drupal-specific file extensions with drupal-mode and *.php and *.inc files as php-mode. You can always explicitly switch to Drupal mode with M-x drupal-mode

(add-to-list 'auto-mode-alist '("\\.\\(module\\|test\\|install\\|theme\\)$" . drupal-mode))
(add-to-list 'auto-mode-alist '("\\.\\(php\\|inc\\)$" . php-mode))
(add-to-list 'auto-mode-alist '("\\.info" . conf-windows-mode))
