C type fontification help

[Kin Cho]

Hi,

I need help fontifying "FOO(a)" as type and "bar" as variable below:

struct foo {
    FOO(a) bar;
};

I tried adding "FOO([^)]+)" to c-font-lock-extra-types but it
doens't help because c-font-lock-extra-types doens't expect word
delimiters.

Also I'd like to fontify "foobar" below as a variable.

void (*foobar)(char *);

The fontification is important to me because I'm using them to
extract semantic information from header files.

Thanks.

You might want to try something like

  (add-hook 'c-mode-hook
    (lambda ()
      (set (make-local-variable 'font-lock-syntactic-keywords)
           '(("FOO([^)]+)" (0 '(2))))))

To first change the syntax-class of the open and close paren to "word".
That's pretty ugly but it should work (probably with some fiddling).

I have given up on relying on font-lock for parsing.

I'm experimenting with xemacs.org's semantic now and it looks
good so far -- although it still wouldn't associate "FOO(a)" as
the type of "bar", but at least "bar" is parsed as a variable.

Thanks.
