  41 ;; This package provides a simple Emacs major mode for editing Vera code.
  42 ;; It includes the following features:
  43
  44 ;;   - Syntax highlighting
  45 ;;   - Indentation
  46 ;;   - Word/keyword completion
  47 ;;   - Block commenting
  48 ;;   - Works under GNU Emacs and XEmacs

  56 ;; Installation
  57
  58 ;; Prerequisites:  GNU Emacs 20.X/21.X, XEmacs 20.X/21.X
  59
  60 ;; Put `vera-mode.el' into the `site-lisp' directory of your Emacs installation
  61 ;; or into an arbitrary directory that is added to the load path by the
  62 ;; following line in your Emacs start-up file (`.emacs'):
  63
  64 ;;   (setq load-path (cons (expand-file-name "<directory-name>") load-path))
  65
  66 ;; If you already have the compiled `vera-mode.elc' file, put it in the same
  67 ;; directory.  Otherwise, byte-compile the source file:
  68 ;;   Emacs:  M-x byte-compile-file  ->  vera-mode.el
  69 ;;   Unix:   emacs -batch -q -no-site-file -f batch-byte-compile vera-mode.el
  70
  71 ;; Add the following lines to the `site-start.el' file in the `site-lisp'
  72 ;; directory of your Emacs installation or to your Emacs start-up file
  73 ;; (`.emacs'):
  74
  75 ;;   (autoload 'vera-mode "vera-mode" "Vera Mode" t)
  76 ;;   (setq auto-mode-alist (cons '("\\.vr[hi]?\\'" . vera-mode) auto-mode-alist))

 260 Usage:
 261 ------
 262
 263   INDENTATION:  Typing `TAB' at the beginning of a line indents the line.
 264     The amount of indentation is specified by option `vera-basic-offset'.
 265     Indentation can be done for an entire region \(`M-C-\\') or buffer (menu).
 266     `TAB' always indents the line if option `vera-intelligent-tab' is nil.
 267
 268   WORD/COMMAND COMPLETION:  Typing `TAB' after a (not completed) word looks
 269     for a word in the buffer or a Vera keyword that starts alike, inserts it
 270     and adjusts case.  Re-typing `TAB' toggles through alternative word
 271     completions.
 272
 273     Typing `TAB' after a non-word character inserts a tabulator stop (if not
 274     at the beginning of a line).  `M-TAB' always inserts a tabulator stop.
 275
 276   COMMENTS:  `C-c C-c' comments out a region if not commented out, and
 277     uncomments a region if already commented out.
 278
 279   HIGHLIGHTING (fontification):  Vera keywords, predefined types and
 280     constants, function names, declaration names, directives, as well as
 281     comments and strings are highlighted using different colors.
 282
 283   VERA VERSION:  OpenVera 1.4 and Vera version 6.2.8.
