I'm adding keyword highlighting to a new major mode I'm writing. I'm
having trouble getting one type to work. I'd like to set any line that
begins with "vms " to font-lock-constant face. I thought something
like this should work:
("^VMS.*$" . font-lock-constant-face)
But the lines don't highlight at all. If I do:
("^VMS" . font-lock-constant-face)
the "VMS" is colored but the rest of the line isn't. If I do this:
("^VMS...." . font-lock-constant-face)
the "VMS" and four characters after are colored. This suggests the
caret and the period are working as expected. Is the engine matching
un-greedily? Any help would be appriciated.
Thanks,
Dan

Well, you're doing the right thing by playing around with it. You would
do well to read up on regular expressions. (But then so would I. B) )
I'm thinking you want something like "VMS .*$"

I have just tested,
("\\(^VMS.*$\\)" 1 font-lock-warning-face prepend)
is working fine (all the line becomes red). may be it is the parantheses
that you lack in yours.
