36 ;;; Commentary:
37 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
39 ;; This package provides a simple Emacs major mode for editing Vera code.
40 ;; It includes the following features:
42 ;; - Syntax highlighting
43 ;; - Indentation
44 ;; - Word/keyword completion
45 ;; - Block commenting
46 ;; - Works under GNU Emacs and XEmacs
48 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
49 ;; Documentation
51 ;; See comment string of function `vera-mode' or type `C-h m' in Emacs.
53 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
54 ;; Installation
56 ;; Prerequisites: GNU Emacs 20.X/21.X, XEmacs 20.X/21.X
58 ;; Put `vera-mode.el' into the `site-lisp' directory of your Emacs installation
59 ;; or into an arbitrary directory that is added to the load path by the
60 ;; following line in your Emacs start-up file (`.emacs'):
62 ;; (setq load-path (cons (expand-file-name "<directory-name>") load-path))
64 ;; If you already have the compiled `vera-mode.elc' file, put it in the same
65 ;; directory. Otherwise, byte-compile the source file:
66 ;; Emacs: M-x byte-compile-file -> vera-mode.el
67 ;; Unix: emacs -batch -q -no-site-file -f batch-byte-compile vera-mode.el
69 ;; Add the following lines to the `site-start.el' file in the `site-lisp'
70 ;; directory of your Emacs installation or to your Emacs start-up file
71 ;; (`.emacs'):
73 ;; (autoload 'vera-mode "vera-mode" "Vera Mode" t)
74 ;; (setq auto-mode-alist (cons '("\\.vr[hi]?\\'" . vera-mode) auto-mode-alist))

256 Usage:
257 ------
259 INDENTATION: Typing `TAB' at the beginning of a line indents the line.
260 The amount of indentation is specified by option `vera-basic-offset'.
261 Indentation can be done for an entire region \(`M-C-\\') or buffer (menu).
262 `TAB' always indents the line if option `vera-intelligent-tab' is nil.
264 WORD/COMMAND COMPLETION: Typing `TAB' after a (not completed) word looks
265 for a word in the buffer or a Vera keyword that starts alike, inserts it
266 and adjusts case. Re-typing `TAB' toggles through alternative word
267 completions.
269 Typing `TAB' after a non-word character inserts a tabulator stop (if not
270 at the beginning of a line). `M-TAB' always inserts a tabulator stop.
272 COMMENTS: `C-c C-c' comments out a region if not commented out, and
273 uncomments a region if already commented out.
275 HIGHLIGHTING (fontification): Vera keywords, predefined types and
276 constants, function names, declaration names, directives, as well as
277 comments and strings are highlighted using different colors.
279 VERA VERSION: OpenVera 1.4 and Vera version 6.2.8.
282 Maintenance:
