Hi,
I need multiline font lock in a major mode that i'm writing. I read in
the elisp manual (and have actually checked it) that using regexps
matching multiple lines in font-lock-keywords is a bad idea. I've also
read the node dedicated to multiline font-lock in the manual, but it's
not clear to me how it works. Could you please point me to an example of
that mechanism being used?
Thanks!
jao

As explained in the manual, there are different mechanisms available,
and which one to use depends on the particular situation.
You can either use syntax-tables to turn your multiline thingy into
a pseudo-comment or pseudo-string (and then use
font-lock-syntactic-face-function to highlight it in a different way).
Or you can use the font-lock-multiline text-property (not to be confused
with the variable) on the multiline elements once you've found them.
Or you can use font-lock-extend-region-functions and use your own ad-hoc
code to make sure that your regexps always get to look at complete
multiline elements.
