24 | ;;; Commentary: | |
25 | ||
26 | ;; To enter Delphi mode when you find a Delphi source file, one must override | |
27 | ;; the auto-mode-alist to associate Delphi with .pas (and .dpr and .dpk) | |
28 | ;; files. Emacs, by default, will otherwise enter Pascal mode. E.g. | |
29 | ;; | |
30 | ;; (autoload 'delphi-mode "delphi") | |
31 | ;; (setq auto-mode-alist | |
32 | ;; (cons '("\\.\\(pas\\|dpr\\|dpk\\)$" . delphi-mode) auto-mode-alist)) | |
33 | ||
95c1652d RB |
34 | ;; To get keyword, comment, and string literal coloring, be sure that font-lock |
35 | ;; is running. One can manually do M-x font-lock-mode in a Delphi buffer, or | |
36 | ;; one can put in .emacs: | |
37 | ;; | |
38 | ;; (add-hook 'delphi-mode-hook 'turn-on-font-lock) | |
39 | ||
40 | ;; If font-lock is not loaded by default, you might have to do: | |
a1506d29 | 41 | ;; |
95c1652d RB |
42 | ;; (autoload 'font-lock-mode "font-lock") |
43 | ;; (autoload 'turn-on-font-lock "font-lock") | |
44 | ;; (setq font-lock-support-mode 'lazy-lock-mode) | |
45 | ;; | |
46 | ;; Lazy lock is very necessary for faster screen updates. | |
47 | ||
48 | ;; For good performance, be sure to byte-compile delphi.el, e.g. | |
49 | ;; | |
50 | ;; M-x byte-compile-file <give the path to delphi.el when prompted> | |
51 | ||
52 | ;; This will generate delphi.elc, which will be loaded instead of delphi.el | |
53 | ;; when delphi-mode is autoloaded. | |
54 | ||
70492703 KH |
55 | ;; When you have entered Delphi mode, you may get more info by pressing |
56 | ;; C-h m. | |
57 | ||
95c1652d RB |
58 | ;; This delphi mode implementation is fairly tolerant of syntax errors, relying |
59 | ;; as much as possible on the indentation of the previous statement. This also | |
60 | ;; makes it faster and simpler, since there is less searching for properly | |
61 | ;; constructed beginnings. | |
