24 ;;; Commentary:
25 ;;; Description:
26 ;;;
27 ;;; This file defines the hm--html-mode, a mode for editing html
28 ;;; files. It is the main file of the package hm--html-menus.
29 ;;; Previous releases had used the file html-mode.el from Marc
30 ;;; Andreessen. In that times the mode was called html-mode. I've
31 ;;; changed the name of the mode to distinquish it from other
32 ;;; html modes. But feel free to set a
33 ;;; (defalias 'hm--html-mode 'html-mode)
34 ;;; to get back the old name of the mode.
35 ;;;
36 ;;; In the earlier releases of the package the main file was
37 ;;; hm--html-menu.el. This has been changed to hm--html-mode.el.
38 ;;;
39 ;;; Installation:
40 ;;;
41 ;;; Put this file and all the other files of the package
42 ;;; in one of your load path directories and the
43 ;;; following lines in your .emacs:
44 ;;;
45 ;;; (autoload 'hm--html-mode "hm--html-mode" "HTML major mode." t)
46 ;;;
47 ;;; (or (assoc "\\.html$" auto-mode-alist)
48 ;;; (setq auto-mode-alist (cons '("\\.html$" . hm--html-mode)
49 ;;; auto-mode-alist)))
50 ;;; If there is already another html-mode (like psgml in the XEmacs
51 ;;; 19.14, then you must put the following instead of the last form
52 ;;; in your .emacs:
53 ;;; (setq auto-mode-alist (cons '("\\.html$" . hm--html-mode)
54 ;;; auto-mode-alist))
55 ;;;
56 ;;; Look at the file hm--html-configuration for further installation
57 ;;; points.
