syntax highlighting on the fly

[lee]

Hi,

is something available with emacs to do to syntax highlighting on the
fly?

"On the fly" means: You have a mode with syntax highlighting which does
most of the highlighting.  Now you work on a file (source code for some
program) in a buffer with your mode enabled, and you decide that for
this particular file, you want "foobar" to be highlighted.

You´d have to somehow tell emacs to do this, for example by adding a
comment like


// highlight: foobar


to your file.  You could also do it like


#define foobar 25


(since you´re using #define anyway) and have all occurances of "foobar"
highlighted.

It´s probably possible to write something for this, and I wouldn´t even
know where to start.  Perhaps it´s already built in and I only don´t
know about it?
