  30 ;; Introduction:
  31 ;;
  32 ;; Whenever a file that Emacs is editing has been changed by another
  33 ;; program the user normally has to execute the command `revert-buffer'
  34 ;; to load the new content of the file into Emacs.
  35 ;;
  36 ;; This package contains two minor modes: Global Auto-Revert Mode and
  37 ;; Auto-Revert Mode.  Both modes automatically revert buffers
  38 ;; whenever the corresponding files have been changed on disk and the
  39 ;; buffer contains no unsaved changes.
  40 ;;
  41 ;; Auto-Revert Mode can be activated for individual buffers.  Global
  42 ;; Auto-Revert Mode applies to all file buffers. (If the user option
  43 ;; `global-auto-revert-non-file-buffers' is non-nil, it also applies
  44 ;; to some non-file buffers.  This option is disabled by default.)
  45 ;; Since checking a remote file is too slow, these modes do not check
  46 ;; or revert remote files.
  47 ;;
  48 ;; Both modes operate by checking the time stamp of all files at
  49 ;; intervals of `auto-revert-interval'.  The default is every five
  50 ;; seconds.  The check is aborted whenever the user actually uses
  51 ;; Emacs.  You should never even notice that this package is active
  52 ;; (except that your buffers will be reverted, of course).
  53 ;;
  54 ;; After reverting a file buffer, Auto Revert Mode normally puts point
  55 ;; at the same position that a regular manual revert would.  However,
  56 ;; there is one exception to this rule.  If point is at the end of the
  57 ;; buffer before reverting, it stays at the end.  Similarly if point
  58 ;; is displayed at the end of a file buffer in any window, it will stay
  59 ;; at the end of the buffer in that window, even if the window is not
  60 ;; selected.  This way, you can use Auto Revert Mode to `tail' a file.
  61 ;; Just put point at the end of the buffer and it will stay there.
  62 ;; These rules apply to file buffers. For non-file buffers, the
  63 ;; behavior may be mode dependent.
  64 ;;
  65 ;; While you can use Auto Revert Mode to tail a file, this package
  66 ;; contains a third minor mode, Auto Revert Tail Mode, which does so
  67 ;; more efficiently, as long as you are sure that the file will only
  68 ;; change by growing at the end.  It only appends the new output,
  69 ;; instead of reverting the entire buffer.  It does so even if the
  70 ;; buffer contains unsaved changes.  (Because they will not be lost.)
  71
  72 ;; Usage:
  73 ;;
  74 ;; Go to the appropriate buffer and press either of:
  75 ;;   M-x auto-revert-mode RET
  76 ;;   M-x auto-revert-tail-mode RET
  77 ;;
  78 ;; To activate Global Auto-Revert Mode, press:
  79 ;;   M-x global-auto-revert-mode RET
  80 ;;
  81 ;; To activate Global Auto-Revert Mode every time Emacs is started
  82 ;; customise the option `global-auto-revert-mode' or the following
  83 ;; line could be added to your ~/.emacs:
  84 ;;   (global-auto-revert-mode 1)
  85 ;;
  86 ;; The function `turn-on-auto-revert-mode' could be added to any major
  87 ;; mode hook to activate Auto-Revert Mode for all buffers in that
  88 ;; mode.  For example, the following line will activate Auto-Revert
  89 ;; Mode in all C mode buffers:
  90 ;;
  91 ;; (add-hook 'c-mode-hook 'turn-on-auto-revert-mode)
