Hi, all

I have been working on implementing a tool-set of code assistance called 
GCCSense, which enables code-completion for C/C++ in editors or a terminal.

http://cx4a.org/software/gccsense/

GCCSense depends on its own GCC which has special options for code 
assistance such like -code-completion-at:

     $ cat
     #include <string>
     int main()
     {
         std::string s;
         s.
     }
     $ # Print completion candidates at line 5 and column 7 of a.cc
     $ g++-code-assist -fsyntax-only -code-completion-at=a.cc:5:7 a.c

Now, I have the following problems:

* Hard to build that GCC for users
* Hard to maintain that GCC for me

Plugin might be a solution for them. Finally, however, I found that 
there is no proper plugin entrances for code assistance. As you may 
understand if you read an attached patch, GCCSense needs to handle 
quickly a special token for code-completion after particular tokens such 
as "." and "->" in parser phase.

Is there any good solution for this ?
Or could you implement such plugin entrances for code assistance ?

Thanks.
