Summary

Minor mode for interactive automatic highlighting

Commentary

With the hi-lock commands text matching interactively entered
 regexp's can be highlighted.  For example, `M-x highlight-regexp
 RET clearly RET RET' will highlight all occurrences of `clearly'
 using a yellow background face.  New occurrences of `clearly' will
 be highlighted as they are typed.  `M-x unhighlight-regexp RET'
 will remove the highlighting.  Any existing face can be used for
 highlighting and a set of appropriate faces is provided.  The
 regexps can be written into the current buffer in a form that will
 be recognized the next time the corresponding file is read (when
 file patterns is turned on).

 Applications:

   In program source code highlight a variable to quickly see all
   places it is modified or referenced:
   M-x highlight-regexp RET ground_contact_switches_closed RET RET

   In a shell or other buffer that is showing lots of program
   output, highlight the parts of the output you're interested in:
   M-x highlight-regexp RET Total execution time [0-9]+ RET hi-blue-b RET

   In buffers displaying tables, highlight the lines you're interested in:
   M-x highlight-lines-matching-regexp RET January 2000 RET hi-black-b RET

   When writing text, highlight personal cliches.  This can be
   amusing.
   M-x highlight-phrase RET as can be seen RET RET

 Setup:

   Put the following code in your init file.  This turns on
   hi-lock mode and adds a "Regexp Highlighting" entry
   to the edit menu.

   (global-hi-lock-mode 1)

   To enable the use of patterns found in files (presumably placed
   there by hi-lock) include the following in your init file:

   (setq hi-lock-file-patterns-policy 'ask)

   If you get tired of being asked each time a file is loaded replace
   `ask' with a function that returns t if patterns should be read.

   You might also want to bind the hi-lock commands to more
   finger-friendly sequences:

   (keymap-set hi-lock-map "C-z C-h" 'highlight-lines-matching-regexp)
   (keymap-set hi-lock-map "C-z i" 'hi-lock-find-patterns)
   (keymap-set hi-lock-map "C-z h" 'highlight-regexp)
   (keymap-set hi-lock-map "C-z p" 'highlight-phrase)
   (keymap-set hi-lock-map "C-z r" 'unhighlight-regexp)
   (keymap-set hi-lock-map "C-z b" 'hi-lock-write-interactive-patterns))

   See the documentation for hi-lock-mode `C-h f hi-lock-mode' for
   additional instructions.

Sample file patterns:

Hi-lock: (("^;;; .*" (0 (quote hi-black-hb) t)))
Hi-lock: ( ("make-variable-buffer-\\(local\\)" (0 font-lock-keyword-face)(1 'italic append)))))
Hi-lock: end
