2333  @subsection Other Font Lock Variables  the value of @code{font-lock-keywords-case-fold-search} which says
2334    whether search-based fontification should be case-insensitive.
   This section describes additional variables that a major mode  
 can set by means of @code{font-lock-defaults}.  
   
 @defvar font-lock-keywords-only  
 Non-@code{nil} means Font Lock should not fontify comments or strings  
 syntactically; it should only fontify based on  
 @code{font-lock-keywords}.  
 @end defvar  
   
 @ignore  
 Other variables include those for buffer-specialized fontification functions,  
 `font-lock-fontify-buffer-function', `font-lock-unfontify-buffer-function',  
 `font-lock-fontify-region-function', `font-lock-unfontify-region-function',  
 `font-lock-inhibit-thing-lock' and `font-lock-maximum-size'.

2340    
2341  @defvar font-lock-syntax-table  You can use @code{font-lock-add-keywords} to add additional
2342  This variable specifies the syntax table to use for fontification of  search-based fontification rules to a major mode, and
2343  comments and strings.  @code{font-lock-remove-keywords} to removes rules.
2344  @end defvar  
2345    @defun font-lock-add-keywords mode keywords &optional append
2346    This function adds highlighting @var{keywords} for @var{mode}.  The
2347    argument @var{keywords} should be a list with the same format as the
2348    variable @code{font-lock-keywords}.  @var{mode} should be a symbol,
2349    the major mode command name, such as @code{c-mode}.  When Font Lock
2350    mode is turned on in @var{mode}, it adds @var{keywords} to
2351    @code{font-lock-keywords}.  @var{mode} can also be @code{nil}; the
2352    highlighting @var{keywords} are immediately added to
2353    @code{font-lock-keywords} in the current buffer in that case.
2354    
2355    By default, @var{keywords} are added at the beginning of
2356    @code{font-lock-keywords}.  If the optional argument @var{append} is
2357    @code{set}, they are used to replace the value of
2358    @code{font-lock-keywords}.  If @var{append} is any other
2359    non-@code{nil} value, they are added at the end of
2360    @code{font-lock-keywords}.
2361    
2362  @defvar font-lock-beginning-of-syntax-function  For example:
 If this variable is non-@code{nil}, it should be a function to move  
 point back to a position that is syntactically at ``top level'' and  
 outside of strings or comments.  Font Lock uses this when necessary  
 to get the right results for syntactic fontification.  
2363    
2364  This function is called with no arguments.  It should leave point at the  @smallexample
2365  beginning of any enclosing syntactic block.  Typical values are  (font-lock-add-keywords 'c-mode
2366  @code{beginning-of-line} (i.e., the start of the line is known to be   '(("\\<\\(FIXME\\):" 1 font-lock-warning-face prepend)
2367  outside a syntactic block), or @code{beginning-of-defun} for programming     ("\\<\\(and\\|or\\|not\\)\\>" . font-lock-keyword-face)))
2368  modes or @code{backward-paragraph} for textual modes (i.e., the  @end smallexample
 mode-dependent function is known to move outside a syntactic block).  
2369    
2370  If the value is @code{nil}, the beginning of the buffer is used as a  adds two fontification patterns for C mode: one to fontify the word

2372  be slow.  @samp{and}, @samp{or} and @samp{not} as keywords.
2373  @end defvar  
2374    Some modes have specialized support for additional patterns.  See the
2375    variables @code{c-font-lock-extra-types},
2376    @code{c++-font-lock-extra-types}, @code{objc-font-lock-extra-types}
2377    and @code{java-font-lock-extra-types}, for example.
2378    @end defun
2379    
2380    @defun font-lock-remove-keywords mode keywords
2381    This function removes highlighting @var{keywords} for @var{mode}.  As
2382    in @code{font-lock-add-keywords}, @var{mode} should be a major mode
2383    command name or @code{nil}.  If @code{nil}, the highlighting
2384    @var{keywords} are immediately removed in the current buffer.
2385    @end defun
2386    
2387    @strong{Warning:} Only use a non-@code{nil} @var{mode} argument when
2388    you use @code{font-lock-add-keywords} or
2389    @code{font-lock-remove-keywords} in your @file{.emacs} file.  When you
2390    use these functions from a Lisp program (such as a minor mode), we
2391    recommend that you use @code{nil} for @var{mode} (and place the call
2392    on a hook) to avoid subtle problems due to the details of the
2393    implementation.

2609    @defvar font-lock-beginning-of-syntax-function
2610    If this variable is non-@code{nil}, it should be a function to move
2611    point back to a position that is syntactically at ``top level'' and
2612    outside of strings or comments.  Font Lock uses this when necessary
2613    to get the right results for syntactic fontification.
2614    
2615    This function is called with no arguments.  It should leave point at
2616    the beginning of any enclosing syntactic block.  Typical values are
2617    @code{beginning-of-line} (used when the start of the line is known to
2618    be outside a syntactic block), or @code{beginning-of-defun} for
2619    programming modes, or @code{backward-paragraph} for textual modes.
2620    
2621    If the value is @code{nil}, the beginning of the buffer is used as a
2622    position outside of a syntactic block.  This cannot be wrong, but it
2623    can be slow.
2624    
2625    Specify this variable using @var{syntax-begin} in
2626    @code{font-lock-defaults}.
2627    @end defvar
2628    
2629    @defvar font-lock-syntactic-face-function
2630    A function to determine which face to use for a given syntactic
2631    element (a string or a comment).  The function is called with one
2632    argument, the parse state at point returned by
2633    @code{parse-partial-sexp}, and should return a face.  The default
2634    value returns @code{font-lock-comment-face} for comments and
2635    @code{font-lock-string-face} for strings.
2636    
2637    This can be used to highlighting different kinds of strings or
2638    comments differently.  It is also sometimes abused together with
2639    @code{font-lock-syntactic-keywords} to highlight elements that span
2640    multiple lines, but this is too obscure to document in this manual.
2641    
2642    Specify this variable using @var{other-vars} in
2643    @code{font-lock-defaults}.
