Hi,
I need some help with an emacs mode for cmake:
www.cmake.org. The mode file we have is here:
http://www.cmake.org/CMakeDocs/cmake-mode.el
The file has the following problem:
; TODO: If anyone knows how to match function names occurring before an
; open-paren and highlight them without also highlighting the
; open-paren, please contact cmake@cmake.org or kitware@kitware.com
; and tell us how to do it. We would rather not have to include the
; entire list of CMake commands in this mode file, which is a pain to
; maintain. Thanks.
Any ideas?
Thanks.
-Bill

There's several things here. First, there's no reason you have to go
through the *scratch* nonsense. Just put the big commented-out
`regexp-opt' call into the `defvar':
(defconst cmake-font-lock-defaults
(list (cons (regexp-opt '("foo" "bar") 'words)
'font-lock-function-name-face))
"Highlighting expressions for CMAKE mode.")
You then don't have to have the 3k output in the file, just the code in
the comment.
I also note that there's a syntax error that makes the doc string actually
be a part of the (list) form. If you want to not force the load of
regexp-opt, you can use `eval-when-compile'; see regexp-opt.el for info.
Moreover, later you do
(setq font-lock-defaults '(cmake-font-lock-defaults))
...which suggests to me that the variable should in fact be called
`cmake-font-lock-keywords' or so, not `...-defaults'.
Now, if you'd really rather get rid of the list altogether, as the comment
suggests, then you can use this as an element of the keywords list:
("\\(\\w+\\)(" 1 font-lock-function-name-face)
The trick is that the 1 says to highlight the first captured expression,
rather than the whole match, and the group doesn't contain the `('.
Moreover, this mode (aside from the indenting) looks to be extremely
simple; you might be able to get away with making it a derived major mode
(from Fundamental mode, probably; see `define-derived-mode') or even a
generic mode (see `define-generic-mode'). Might make it less trouble to
keep up with.
Hope it helps,
Davis

Yeah, I've found `define-generic-mode' to be very helpful for my own
language modes: it makes font-locking and basic mode definition details
almost trivial, and usually doesn't get in the way of adding additional
functionality.
I think it really deserves more attention than it seems to get
(is d-g-m more or less compatible between Emacs 21 and 22?).
[Now if only there was a similarly easy way to define an indentation
engine... :-]
