[cfe-dev] clang indexing server for emacs?

[Eran Ifrah]

Actually I am working on something similar.
I started integrating clang code-completion in the IDE that I have
developed and grown quite mature (open source, cross platform
www.codelite.org)

However, currently it is used *inside* the IDE and not as an external
service. But 'extracting' it should be an easy task.

The current state of the 'completion' is that is capable of providing
a completion list by executing clang from the command line. I am at a
point right now where I am implementing the cache based on the
pre-compiled header:
When a file is opened inside the editor, I am extracting all the
include statements from the file and forming a 'pre-compiled' header
which is being compiled in the background.
This file is then used with clang with the '-include-pch' switch to
boost the completion speed.

It looks promising (talking speed wise), but still a bit slower than
the current code completion - but I think its worth the effort.

Developing a custom protocol is an easy task (I already got all the
infrastructure required for this (Windows Named pipe/Domain Sockets
etc)
The only thing I am not sure that I can get from the 'clang' atm
(*without* linking against libclang) is the location of the match

If I had the location, of the match, I could also parse any doxy
comment on top of that method and return it along with the match (this
is how the current code completion works)

Any ideas whether this is feasible? or must I link against libclang?
