;; This file is part of GNU Emacs.
;; it provides a visual mark for characters, for example, at the end
;; of line (?\xB6), at SPACEs (?\xB7) and at TABs (?\xBB).
;;
-;; The `whitespace-style' and `whitespace-chars' variables are used to
-;; select which way should be used to visualize blanks.
+;; The `whitespace-style-mark' and `whitespace-style-color' variables
+;; are used to select which way should be used to visualize blanks.
;;
;; Note that when whitespace is turned on, whitespace saves the
;; font-lock state, that is, if font-lock is on or off. And
;;
;; There are also the following useful commands:
;;
+;; `whitespace-report'
+;; Report some blank problems in buffer.
+;;
+;; `whitespace-report-region'
+;; Report some blank problems in a region.
+;;
;; `whitespace-cleanup'
;; Cleanup some blank problems in all buffer or at region.
;;
;; `whitespace-cleanup-region'
;; Cleanup some blank problems at region.
;;
-;; `whitespace-buffer'
-;; Turn on `whitespace-mode' forcing some settings.
-;;
;; The problems, which are cleaned up, are:
;;
;; 1. empty lines at beginning of buffer.
;; 2. empty lines at end of buffer.
-;; If `whitespace-chars' includes the value `empty', remove all
-;; empty lines at beginning and/or end of buffer.
+;; If `whitespace-style-color' includes the value `empty', remove
+;; all empty lines at beginning and/or end of buffer.
;;
;; 3. 8 or more SPACEs at beginning of line.
-;; If `whitespace-chars' includes the value `indentation', replace
-;; 8 or more SPACEs at beginning of line by TABs.
+;; If `whitespace-style-color' includes the value `indentation':
+;; replace 8 or more SPACEs at beginning of line by TABs, if
+;; `indent-tabs-mode' is non-nil; otherwise, replace TABs by
+;; SPACEs.
+;; If `whitespace-style-color' includes the value
+;; `indentation::tab', replace 8 or more SPACEs at beginning of line
+;; by TABs.
+;; If `whitespace-style-color' includes the value
+;; `indentation::space', replace TABs by SPACEs.
;;
;; 4. SPACEs before TAB.
-;; If `whitespace-chars' includes the value `space-before-tab',
-;; replace SPACEs by TABs.
+;; If `whitespace-style-color' includes the value
+;; `space-before-tab': replace SPACEs by TABs, if
+;; `indent-tabs-mode' is non-nil; otherwise, replace TABs by
+;; SPACEs.
+;; If `whitespace-style-color' includes the value
+;; `space-before-tab::tab', replace SPACEs by TABs.
+;; If `whitespace-style-color' includes the value
+;; `space-before-tab::space', replace TABs by SPACEs.
;;
;; 5. SPACEs or TABs at end of line.
-;; If `whitespace-chars' includes the value `trailing', remove all
-;; SPACEs or TABs at end of line."
+;; If `whitespace-style-color' includes the value `trailing',
+;; remove all SPACEs or TABs at end of line.
;;
;; 6. 8 or more SPACEs after TAB.
-;; If `whitespace-chars' includes the value `space-after-tab',
-;; replace SPACEs by TABs.
+;; If `whitespace-style-color' includes the value
+;; `space-after-tab': replace SPACEs by TABs, if `indent-tabs-mode'
+;; is non-nil; otherwise, replace TABs by SPACEs.
+;; If `whitespace-style-color' includes the value
+;; `space-after-tab::tab', replace SPACEs by TABs.
+;; If `whitespace-style-color' includes the value
+;; `space-after-tab::space', replace TABs by SPACEs.
;;
;;
;; Hooks
;; Below it's shown a brief description of whitespace options, please,
;; see the options declaration in the code for a long documentation.
;;
-;; `whitespace-style' Specify the visualization style.
+;; `whitespace-style-mark' Specify which kind of blank is
+;; visualized via display table.
;;
-;; `whitespace-chars' Specify which kind of blank is
-;; visualized.
+;; `whitespace-style-color' Specify which kind of blank is
+;; visualized via faces.
;;
;; `whitespace-space' Face used to visualize SPACE.
;;
;; `whitespace-mode' is automagically
;; turned on.
;;
+;; `whitespace-action' Specify which action is taken when a
+;; buffer is visited, killed or written.
+;;
;;
;; Acknowledgements
;; ----------------
;;
+;; Thanks to Stephen Deasey <sdeasey@gmail.com> for the
+;; `indent-tabs-mode' usage suggestion.
+;;
+;; Thanks to Eric Cooper <ecc@cmu.edu> for the suggestion to have hook
+;; actions when buffer is written or killed as the original whitespace
+;; package had.
+;;
;; Thanks to nschum (EmacsWiki) for the idea about highlight "long"
;; lines tail. See EightyColumnRule (EmacsWiki).
