Hi,

Unfortunatly, these kind of features are more rarely found for C++,
since C++ is almost impossible to parse (while its easily possible to
write a complete parser for Java in one afternoon, the same endeavor
will take you at least half a year for C++ :-( And even then its
incomplete.)

However, there are approximate solutions for emacs, that can basically
index the code and provide for quick search: etags. Never used it
myself (I am an old-school bare GNU-emacs user), but many people can
not work without it.

There is a very simple autocomplete function that just looks in the
current file for matching words (usually bound to M-/ (in emacs-speak,
otherwise known as Alt-/)). But as I said, this only looks into the
current file. It works out of the box and doesn't require etags to be
set up.

These features should be covered by etags.

I am not sure about this one.

Having said that, I always wanted to write some useful tool that does
all this for C++; implementation would be running as server that gets
the source directories and can be asked by editors via a socket
connection - thus its trivial to write interfaces to
emacs/vi/whatever. However, the half-year of writing a decent parser
always turned me off.
Anyone who wants to participate ?

You might want to look as well at kdevelop http://www.kdevelop.org/ as
well. AFAIK, they try to provide similar features. Have never tried
it, though.
Give feedback to the list once you decided .. would be interesting.
