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 ;;;
|
|
26
|
56 ;;; But you can also use the hm--html-minor-mode as an addition to
|
|
|
57 ;;; the psgml html modes. For that you've to put the following line in
|
|
|
58 ;;; your .emacs:
|
|
|
59 ;;; (add-hook 'html-mode-hook 'hm--html-minor-mode)
|
|
|
60 ;;;
|
|
|
61 ;;; Note: This works only in an XEmacs version greater than 19.14 and
|
|
|
62 ;;; also not in the XEmacs 20.0.
|
|
|
63 ;;;
|
|
2
|
64 ;;; Look at the file hm--html-configuration for further installation
|
|
|
65 ;;; points.
